The invention relates to mechanical engineering and can be used, for example, the different modes of transport, as well as devices for unstressed enable the driven shaft in order to convert torque.

Known centrifugal clutch, under the constructive execution of one of the most approaching to the claimed technical solution containing the driving and driven coupling (see, for example, as the USSR № 804934 IPC7F 16 D 43/18, published 18.02.81 year).

Leading this coupling centrifugal clutch (hereinafter in the description of the "clutch") made in the form of rigidly mounted on the shaft a disk movable in radial directions of the plungers, ending with massive rollers on axes. Slave coupling is made in the form of a drum, which is placed an elastic annular holder and located between it and the elastic drum chamber filled with a working medium under static pressure and vulcanized to the drum and the holder.

During the rotation of the leading coupling within a housing having the shape of a circle, it torque does not occur. Perepiska working environment of one of the pair of elastic chambers to another, it is possible to smoothly change the shape of the clip from circular to ellipsoidal. When this occurs unstressed enable slave coupling and transmitting torque according to the t load centrifugal forces obkatyvalisj inside the cage rollers.

The disadvantages of this coupling is the following. Torque on the driven coupling half is only due to centrifugal force of the rollers, so at low revs leading coupling value is transmitted to the driven coupling half time low and at high speeds the centrifugal load from the massive rollers on the axle and yoke grow, which can lead to the destruction of the axes. Further, the yoke has a low stabilization in the cylindrical housing driven half-coupling, and the process by-passing the working medium from one of the pair of chambers to another is a difficult problem.

Also known centrifugal clutch, under the constructive implementation of the most approaching to the claimed technical solution, in which the leading coupling is made in the form of freely planted on litovany shaft tied in pairs by rods, at least two pairs to balance the clutch disks with deaf tangential grooves, which are monolithic blade, ending in a massive cylindrical bars, disks with blades and in neutral, and in the working position inside the rings, arranged in a cylinder filled with a lubricating fluid, with the possibility of radial displacement along the guide rails and mounting shifted in diametrically opposite directions relative to each other (see, for example,, RF patent№ 2019752, 15.09.94, IPC7F 16 D 43/18) - the nearest equivalent.

This centrifugal clutch works as follows. Within the threshold of idle leading coupling ring can not move in a given direction under the action of centrifugal forces, because they are weak. However, the slave coupling already occurs until a slight torque due to the action shifted on the installation ring hydrodynamic impulses. With the increasing speed above idle, the eccentricity of the rings increases, respectively, increases the action gidroimpulsov and centrifugal forces. Torque on the slave coupling smoothly and unstressed increases and becomes maximum as soon as the ring will be pressed against the cylindrical body. When this torque on the slave coupling is changed automatically depending on the load. By reducing the number of revolutions of the leading coupling to blank everything happens in reverse order.

The disadvantages of the known couplings of the following.

1. The blade, ending in a massive cylindrical bars under the influence of centrifugal forces from the huge effort put pressure on the line on the inner surface of the rings, causing them for a short time formed roughness and burrs, and this leads to fragility of the coupling.

2. Manufacturing drives deaf tangential slots Ethnology the but.

3. Low efficiency centrifugal clutch. This is due to the fact that in the passive zone on the semicircle, the opposite is active during the rotation of the leading coupling continuous process of increasing myelopathic volumes filled with lubricating fluid. This will signify useless work in the so-called effect of "rasklapanje" vessels filled with liquid. Imagine a glass cylinder filled with water, and there is a piston in contact with water. If you abruptly pull the piston, the cylinder will burst.

4. There is no clear inclusion slave coupling from the threshold value of idle leading coupling.

Known mechanical, three-way, four-speed transmission with four forward and one gear to reverse. Synchronizers are used at all speeds forward (see, for example, Guidance on repair, operation and maintenance of automotive vehicles", publishing house "Wheel", Moscow, 2002) - the nearest equivalent.

Four-speed transmission consists of primary, secondary and intermediate shafts, respectively, and gear. On the secondary shaft between the gears are synchronizers. To enable one of the transmission needs to shift one of the synchronizers in the desired position. If this is m first frictional contact between the necessary gear and synchronizer, then the conical teeth of the synchronizer are tapered gear teeth and is a hard link.

The disadvantages of the known gear box changes gear the following.

1. The main disadvantage is the presence of synchronizers in a box changes gear (transmission).

2. The presence of synchronizers increases the dimensions of the transmission axis.

3. Due to the large number of parts are frequent breakage of the CPR.

The technical result is to increase the efficiency of the functioning of the ISU, its control systems, gear box changes gear (transmission) for the Converter and how to convert them torque.

In the application complied with the principle of unity of invention, since the proposed ISU system control, transmission to Converter and method for converting their torque have the same purpose, serve one purpose, achieve the same technical result, and interconnected to form a single inventive concept, as described by the claims. When is that the concept of legal protection based on the continuity and interconnectedness of the proposed facilities, and the allowable variance of execution of certain essential features or their aggregates determine, including non-traditional nature of the wording of some of the signs. For example, design features of the proposed GUI is reflected not only by the characteristics of its constituent nodes and their structural relationships, but with the help of functional or structural analogues characterizing the device, for example, filling the internal cavity of the ISU lubricating fluid, which is an essential structural component is an analogue for the practical implementation of technical solutions.

This technical result is achieved by the fact that in the GUI that contains the master and slave nodes of the Converter, where the master node of the Converter is implemented in the form of freely planted on litovany the drive shaft with the slots in which the blades are, for example, ended cylindrical bars. The slave node of the Converter is implemented in the form of a cylindrical body with the driven shaft and mounted in rings, inside of which are disks with blades of the master node of the inverter. The slots in the disk host Converter is a through and tangentially, and each blade can be drawn from t is nkiye elastic plates. In the cylindrical housing of the slave node of the inverter each ring mounted for oscillation on a guide, which is bonded with the axis embedded in the bed of the thrust bearing, the body which, for example, by mounting dovetail entered into rigid engagement with the cylindrical housing, one end cap which may be made in concert with the driven shaft.

This technical result is also achieved by design features perform the essential features of the claimed GIP, which:

- on the master node of the Converter outside of discs placed on the shaft of a solid plate of the same diameter, limiting the blades from falling out of the disks and is made of a material, for example bronze, with a lower coefficient of friction is calgene about the material of the blades.

- on the master node of the inverter solid plates, disks with blades, ring, and sleeve are assembled in a package and sealed permeating these elements are rods, beams outside the solid plates under reamer, in line with their planes.

- on the master node of the inverter maximum disk size with solid plates made with overlapping end surfaces of the rings.

- on the slave node of the Converter, each of the rings on the semicircle, facing the guide, made with through-holes.

- on the slave node of the Converter, each of the rings are pinned with the ability to swing the thrust bearing on the shoulder, equal to its diameter.

- an internal cavity for 85-90% of its volume filled with lubricating fluid, such as engine oil LUKOIL (synthetic) SAE SW-40 API SJ/CF.

- provided its execution with the possibility of equipping one of the systems control movement of the rings of the Central eccentric position to control switching on the slave node of the inverter from a given number of revolutions of a driving node of the Converter, for example electromagnetic, hydraulic or pneumatic, hand or foot, and remote system management the Oia.

This technical result is also achieved by using the system management GUI, made in the form of device for generating the control of an electrical signal in the range of a discrete set of frequencies of rotation of the master node of the inverter, which is connected with the actuating mechanism to enable the slave node of the Converter.

In the system management GUI, vklyucheno device for generating the control of an electrical signal related to the scale and arrow tachometer containing unit control signal and is made, for example, by contact or contactless schemes with the ability to influence the number of revolutions of a driving node of the inverter, drive shaft which is directly and rigidly connected to the flywheel of the engine, and a device connected with an actuating mechanism to enable the slave node of the Converter.

The device unit in the control system of the ISU may be made in the form of modifications, in which:

- on the scale of the tachometer installed a rotating ring, mainly in the form of limb, site enable with miniature contacts, with contact closure when the movement of the tachometer needle connected to the input of the amplifier, the output of which is connected with the thyristor key connected to the coils of the electromagnets, and the device connected to ispolnitellnym mechanism enabling the slave node of the Converter.

- limb installed the switch with the possibility of closure of its contacts when the movement of the tachometer needle through the impact attached to the arrow a miniature permanent magnet reed switch with the possibility of closure of its contacts when the movement of the tachometer needle through the impact attached to the arrow a miniature permanent magnet, and the device is connected with the actuating mechanism to enable the slave node of the Converter.

with the limb stiffening miniature U - shaped hour, on one of the branches which is a miniature radiation source, for example a semiconductor laser, and the other branch hours are foetoprotein with the possibility of transfer of radiation that is connected to the node enable with miniature contacts, with contact closure at the intersection of the arrow tachometer flux reed switch with the possibility of closure of its contacts when the movement of the tachometer needle through the impact attached to the arrow a miniature permanent magnet, and the device is connected with the actuating mechanism to enable the slave node of the Converter.

The actuator control system of the ISU, which is connected with the actuating mechanism to enable the slave node of the Converter, into a cylindrical cor the USA slave node of the Converter, in the longitudinal grooves, installed the bracket with tapered protrusions opposite the middle of the ring, who in this place set the pins with round head, massive ends of the slats are made in the form of cores of the electromagnets and placed in an electric coil located on the surface of the end caps, sealed with the driven shaft. The solenoid actuator can be located in the plane of the end cap can be installed in any place, and their cores are thus coupled to the ends of the slats by means of rods, such as a rocker arm or actuator may be in the form of diametrically located plate connected with the ends of the slats facing out through the seal in the end cap of the transducer and mounted on the splined section of the driven shaft planet carrier, a ring recess which entered fork rocker, with the possibility to perform oscillatory movements from the effects of the solenoid, hydraulic or pneumatic cylinder, manually or by pedal.

This technical result is also achieved by using the box changes gear for the ISU containing primary, secondary, and intermediate shafts, an auxiliary axis and the short axis, shrunk in the wall of the housing, intermediate gear, so that they can move on VSP the service axis. In the body of the secondary shaft entered the drive shaft with its end part. On the primary shaft has two rigidly mounted thereon gears, the first of which is constantly meshed with the first gear rigidly mounted on the intermediate shaft and the second mounted for engagement with the intermediate gear. On the secondary shaft has three gears, the first of them, is rigidly mounted on a shaft mounted for engagement with the intermediate gear. Second, freely mounted on the shaft, constantly meshed with the second gear rigidly mounted on the intermediate shaft and mounted for engagement with the intermediate gear. The third gear of the output shaft is rigidly fixed on her and constantly meshed with the gear located on the short axis. The intermediate gear is connected with the host planet carrier, the opening of which is inserted the worm shaft can move drove through the screw joint with the worm shaft. The worm shaft is connected to the disk, with the possibility of it moving through the friction lining disk connected with the steering motor. In the box changes gear may be on the end portion of the primary shaft set needle bearing.

This technical result is achieved also for the use of hydraulic - inertial way to convert torque, comprising bringing into rotation of the drive shaft, which lead through disks are located in their grooves blades, the rotation of the N1- dynamic, mutable, megapath volume of the working fluid, where 3≤N1≤1000, holding the coincidence of the axes of symmetry N; ring and drive shaft, where 1≤N2≤100. While the number of disks, limiting ring, which moves the blades forming the N1megapath volumes, choose equal to 2N2.

Minimum V1and maximum V2values megapath volume change within 1,02≤(V1+0,9V2)/V2≤1,75. Further, the offset rings create an imbalance of the center of mass of the blades, moving the center to a distance of L1, the value of which is chosen in the range of 0.12≤1,1L1/L2≤0,95, where L2- internal diameter of the ring is chosen depending on the maximum value of ϕ - the angle between the directions of movement of the blades and the radius conducted at the point of intersection of this direction with the inner circumference of the ring. The ratio between the minimum value ϕ1and the maximum value of ϕ2this angle is chosen in the range from 1.1≤(ϕ1+1,2ϕ2)/ϕ2≤1,9.

Thereby form the total led the torque Rfrom its hydraulic PGand inertial PAndcomponents in the form ofwhere a is an experimental constant of proportionality between the value of PGthe hydraulic component of the torque and the maximum value (V2-V1) changes megapath volume of the working fluid, V3- the amount of working fluid discharged from the volume V; for damping cavitation,the rotational speed of the driven shaft. In experimental coefficient of proportionality between RAndand a total imbalance masses D, shoulder length L1determined by the amount of movement of the center of mass when the maximum deviation of the ring from its position in the idling mode, and. As a result, the leading P1torque is converted into slave R2torque values which link the ratio of 1≤(P1+P2)/P1≤6,1.

The selection of the damping amount of the Bonds of the working fluid produced by passing through the through hole of the ring, on the side, protivovospalitelnoe with respect to the axis of swing. For optimization purposes the maximum value of V3megapath volume of working fluid adjust using the experimental ratioα 1selected depending on the type of working fluid and the maximum number of N1megapath volumes in the range of 0.05≤α1≤1,3. The value of L1move the center of mass is chosen taking into account the experimental ratio α2selected depending on the angle ϕ between the direction of movement of the blades and the radius translated at the point of intersection of this direction with the inner circumference of the ring within 0,68≤α2≤1,4. The maximum angle ϕ2chosen, taking into account the experimental ratio α3selectable depending on the number of blades and the inner diameter of the ring within 0,54≤α3≤1,7.

Maximum hydraulic slave component torque adjusting to optimize using the experimental ratio And selectable in the range of 0.08 Nm sec≤≤0,21 Nm s (N - Newton), and the maximum value of the inertial component of the slave torque adjust using the experimental ratio In selected within 12 H sec kg-1≤≤14 102H s kg-1.

In more detail the essential structural features of the declared objects and functional interaction of their basic structural elements can be characterized as follows. In accordance with the invention in the ISU containing master and slave nodes of the inverter, the master node of the Converter is implemented in the form of freely planted on litovany shaft 1 drives 2 and 3, 4 and 5 (see Fig. 1, 2, 3) through the tangential grooves in which are placed the blade 6, recruited from rectangular plates. The slave node of the Converter is implemented in the form of a cylindrical body 7 with end caps 8 and 9, where in the lid 8 from the side of the driving shaft 1 there will condense the aspects of the ring 10. In the housing 7, each of the rings 11 and 12 mounted for oscillation along the guide 13. For this purpose, each of the rings 11, 12 are fastened to the axle 14 embedded in the bed of the thrust bearing 15, the body through which mounting dovetail is in rigid engagement with the cylindrical casing 7, one of the end caps 9 which is made in concert with the driven shaft 16.

Between the disks, Chicoana shaft 1, is a cylindrical sleeve 17 with the slots in the disks 2 and 3, 4 and 5, and has at the ends of the ring groove 18 for the message of lubricant outside of the blades 6. Outside of the disks 2, 3, 4 and 5, of the same diameter and also seated on the shaft 1 and has a solid plate 19 (figure 4), which limit the blade 6 from falling out of the disks 2, 3, 4 and 5 and may be made of another, such as bronze, material for the best slip on them blades 6. The disks 2, 3, 4, and 5 with 6 blades, solid plate 19, the ring 11 and the sleeve 17 are assembled in a package and sealed permeating these elements are rods 20, flared outside the solid plate 19 under the reamer, in line with their planes. The disks 2, 3, 4 and 5 with solid plates 19 overlap the end faces of the rings 11,12 so that in the Central and in the maximum eccentric position of the rings 11,12 blades 6 were completely in the grooves of the disks 2, 3, 4, and 5.

A cylindrical housing 7 slave node p is OBRAZOVATEL outside and inside ribbed for good heat transfer. Each of the rings 11 and 12 on the semicircle, facing the guide 13 has a through hole 21. Rings 11 and 12 can swing in the thrust bearings 15 on the shoulder, equal to their diameters (with the axis of rolling 01a in figure 2). The inner cavity of the ISU for 85-90 % of its volume filled with lubricating fluid, such as engine oil, which is the working fluid, and, consequently, the variation of the structural element of the Converter.

The ISU can be equipped with one of the systems control movement of the rings 11,12 Central in the eccentric position, i.e. a management system enabling the slave node of the Converter depending on a given number of revolutions of a driving node of the Converter, for example by electromagnetic, hydraulic or pneumatic, manual or pedal and remote control system. The control system consists of a device for generating a control signal (electric, acoustic, and others) in discrete predetermined rotational speed range of the master node of the inverter, and an actuating mechanism for enabling the slave node of the Converter.

The device for generating the control signal (hereinafter in the description of the "unit") may be performed, for example, contact and contactless schemes and tied somehow to the scale and arrow tachometer,and is equal to the number of revolutions of a driving node of the Converter, drive shaft 1 which is directly and rigidly connected to the flywheel of the engine. The device knob can also be made in the form prescribed in the scale of the tachometer slewing ring with a miniature contact during the passage through it of the tachometer needle is closed, sending a signal to the amplifier, it is a powerful control pulse is fed to the thyristor key, opening or blocking the flow of current to the coil 22. The device knob can also be installed on the limb of the reed switch. The arrow tachometer while glued miniature permanent magnet. With the passage of the tachometer needle over the reed switch, the magnet acts on the contacts and closes them. The signal is then fed to the amplifier and the electronic "key"that opens the flow of current to the coil 22, powered via the slip ring 23 with the plate 24.

The unit can be performed by the contactless scheme. On one of the branches of the U - shaped stand firmly attached to the limb, there is a miniature light source, for example a semiconductor laser, and on the other branch of the rack - foetoprotein. At the intersection of the arrow tachometer light beam magnitude photoshoprecovery changing. This enables the amplifier and the electronic "key"that opens the flow of current to the coil 22. Upon further movement of the tachometer needle beam Cvetanova will fall on foetoprotein and the unit returns to its original state. Due to the fact that it is widely known in the art, the circuit of the generator, amplifier and electronic "key" not shown.

The actuator can be performed as follows. Within the cylindrical body 7 slave node GUI installed strap 25 (figure 5, 6) with a conical protrusions 26 in the middle of the rings 11 and 12, which in this place there are pins 27, round head, heavy ends 28 of the slats 25 are placed in an electric coil 22 and are the cores of the electromagnets. Coil 22 is located in the plane of the end cap 9. The electromagnets can be installed on the plane of the end cover 9 in any place, their cores at that articulate with the ends 28 of the slats 25 through the rod, such as a rocker.

The actuator can also be carried out in the form of a plate 29 (7) with holes connected with the planet carrier 30 mounted on the splined section of the driven shaft 16. The ends 28 of the slats 25 are passed through the seal, for example, in the form of seals 31 (Fig) in the end cap 9 and are fastened to the plate 29. When moving carrier 30 with a fork 32 of the strap 25 is shifted longitudinally and tapered protrusions 26 of the slip rings 11, 12 in diametrically opposite directions.

Figure 9 shows box changes gear for the ISU. It contains 16 primary, secondary 33 and intermediate 34 is Aly, the secondary axis 35 and the short axis 36, shrunk in the wall of the housing 37, the intermediate gear 38, can be moved on a secondary axis 35. In the body of the secondary shaft 33 entered primary shaft 16 with its end part 39, on which is mounted a needle bearing 40. On the primary shaft 16 has two rigidly mounted thereon gears 41 and 42, the first 41 of which are constantly meshed with the first gear 43 fixed on the intermediate shaft 34, and the second 42 is mounted for engagement with the intermediate gear 38. On the secondary shaft 33 has three gears 44, 45 and 46, the first 44 of them rigidly mounted on the shaft 33, mounted for engagement with the intermediate gear 38. The second 45 of them, freely mounted on the shaft 33, constantly meshed with the second gear 47, rigidly mounted on the intermediate shaft 34, and mounted for engagement with the intermediate gear 38. The third gear 46 of the secondary shaft 33 is constantly meshed with the gear 48, located on the short axis 36. The intermediate gear 38 is connected with the host planet carrier 49, the bore of which is inserted the worm shaft 50, with the ability to move the carrier 49 by means of a threaded joint with the worm shaft. The worm shaft 50 connected to the disk 51, with the possibility of it moving through Ricci is nnow gasket 52 of the disk 53, connected with the control motor 54.

The ISU and the box changes gear Assembly depicted in figure 10, which shows the numbers: primary shaft of the master node of the inverter 1, the housing of the slave node of the inverter 7, the front end cover of the slave node of the inverter 8, the rear end cover of the slave node of the inverter 9, the driven shaft of the slave node of the inverter 16, the massive end of the strap 28, the plate of the actuator 29, drove 30, the plug 32, the secondary shaft of the change gear 33, the casing of the gear box changes gear 37, the motor 54, the rib slave node of the inverter 55, protective (fixing) the casing 56, the liquid pipe cylinder 57, the hydraulic cylinder 58, the piston rod of the hydraulic cylinder 59, the wire of the motor minus 60, wire motor with a plus sign 61.

Driven shaft 16 of the slave node of the Converter is shrinked in the end cap 9 of the transducer and serves as the primary shaft gear box changes gear. The ISU is enclosed in a protective casing 56, which is connected with the gear change transmission. The hydraulic cylinder 58 is attached to the casing 56 and serves to move the fork 32. The wire 60 minus motor 54 is attached to the housing wall 37 of the box changes gear. The wire 61 with a plus sign is connected with the positive battery cable to the engine.

The ISU operates as about the time. To the value of the number of revolutions of a driving node of the inverter, set by the setting device, rings 11,12 occupy in the housing 7 slave node of the inverter Central position, since the oil volume inside them is uniformly distributed state. In this case, the blade 6 is not transmitted to the rings 11, 12 and rigidly associated housing 7 with the driven shaft 16 of the torque. When the knob of the control signal, the actuator (knob and the actuator can be selected from the proposed description) shifts the strap 25 longitudinally and the tapered protrusions 26 of the slip rings 11, 12 in diametrically opposite directions. In this case, the slave node of the Converter occurs smoothly and unstressed, but rapidly increasing torque from the first hydrodynamic pulses, and then with increasing speed of the master node of the Converter and from the inertial forces of the blades 6.

Dropping the number of revolutions of a driving node of the Converter to stall action of centrifugal forces of the blades 6 on the rings 11, 12 is weakened and they are under the influence of the oil volume, which aims to take a uniformly distributed state, return to the center position. The pins 27 of the rings 11, 12 are pressed on the tapered sections 26 of the strips 25 and they returned to the original position.

If we consider what abotu one module, and it can be described as tied rods 20 a package of two solid plates 19 of the two disks 2, 3 and sleeve 17, it can be noted that, when the ring 11 is in the maximum eccentric position, the blade 6 is do reciprocating motion in the shoulder 0d (figure 2) from the main axis of the transducer. While on the semicircle of the sun (passive area) increases megapath volumes, and on the semicircle St (active area) - reduce them. Oil, squeezed from the active zone of s through the through holes 21 are freely absorbed in meglomania volumes, forming a ring 11 running belt, facilitating intensive cooling fin inside and outside of the cylindrical body 7 slave node of the inverter. On the master node of the inverter load is reduced and, hence, increases the efficiency of the Converter.

The blade 6 when the eccentric position of the ring 11 make a reciprocating motion in the tangential grooves of the disks 2 and 3 on the shoulder 0d length L1(2) from the main axis of the transducer and always fully recessed in grooves, which also increases the efficiency and reliability of the module. The blade 6 is made in the form of a package of thin plates, not monolithic, it is unloaded pressure on the inner surface of the ring 11, which increases the durability of the Converter.

The slave node preobrazovatelnaja to include a wide range of frequencies of rotation of the master node of the Converter, as well as the push of a button is to turn off the unit, for example when warming up the engine.

Box changes gear operates as follows. Idle speed and engine warm-up is provided by the off-system control slave node of the Converter, in this case, the intermediate gear 38 may be located in any position on the axis 35, then the gear 38 moves in one of the desired positions, for example for driving on smooth, without biases the road it engages with the gears 42 and 44, in this case, the transfer torque directly from the GUI on the primary shaft 16 of the gear box changes gear.

To propel the vehicle along the serpentine idler gear 38 is in mesh with gears 44 and 45, in this case, redaktirovaniya with a specified rate of forward movement. For driving back the intermediate gear 38 is introduced into engagement with the gears 45 and 48. When the direction of rotation of the gear 45 with the reduction coincides with the direction of rotation of the shaft 16, through passive gear 48 changing the direction of rotation of the gear 46, and accordingly, the output shaft 33 to the opposite. Control gear 38 carried by the planet carrier 49, through which the screw joint screw shaft 50 can move in the desired position. The worm is hydrated shaft 50 through the disks 51 and 53 with friction pads 52 is driven by motor 54.
