The scope of the invention

The present invention relates to power transmissions. In particular, the invention relates to a transmission with continuously variable speed change.

The existing level of technology

To provide an infinitely variable transmission developed various traction roller transmission in which the power is transmitted through the traction rollers are held in the housing between the input and output torque drives. In such transmissions traction rollers are mounted on supporting structures, which upon rotation causes the grip of the traction rollers with torque drives in circles with varying diameters depending on the desired gear ratio.

However, the success of these traditional solutions limited. For example, in U.S. patent No. 5236403 name Schievelbusch disclosed transmission for a vehicle with variable adjustable gear ratio. Schievelbusch discloses the use of two iris-diaphragm plates, one on each side of the traction rollers to tilt the axis of rotation of each roller. However, the use of iris-diaphragm plates can be very difficult due to the large number of parts that are required to adjust the iris-diaphragm plates during shift transmission. The other is associated with the given transmissie the difficulty is that, it contains guide ring configured so that it is mostly stationary with respect to each of the rollers. Since the guide ring stationary, shift the axis of rotation of each of the traction rollers problematic. Another limitation of this design is that it requires the use of two axes, one on each side of the rollers, to provide a gap in the middle between the two axes. This clearance is necessary, since the rollers are shifted by the rotational motion, not moving linear motion. The use of two axes is undesirable and require complicated mounting system to prevent bending axes at random impulse transmission, which often happens when using the transmission in the vehicle. Another limitation of this design is that it does not provide an automatic transmission.

There is therefore a need for a transmission with continuously variable speed change with more simple way switching, single axis, and a support ring having an almost uniform outer surface. Additionally, there is a need for automatic transmission with traction rollers, which are configured for automatic switching. Next, practical commercial availability is of transmissi with traction rollers requires increased reliability, ease of switching, operation and design of the transmission.

For example, the present invention can be used in mechanisms such as drill presses, turbines and equipment for food processing, as well as in such vehicles as cars, motorcycles and bicycles.

A detailed description of the preferred execution

Further detailed description is directed to certain specific embodiments of the invention. However, the invention can be implemented in many different ways, as defined in the claims. In this description reference is made to the drawings, in which identical parts are marked with the same numbers. Moreover, embodiments of the invention may contain several new features, none of which individually is not responsible for desirable properties, or which are necessary to implement in practice inventions described here.

The present invention provides the transmission with a continuously variable speed change, which can be used socetanii with any type of mechanism, in need of transmission. For example, transmission can be used in (i) a motor vehicle such as car, motorcycle or boat, (ii) non-motorized vehicle, such as a Bicycle, tricycle, scooter, equipment for physical exercise, or (iii) industrial equipment such as drill press, power generating equipment or textile factory.

Figures 1 and 2 reveals the transmission 100 with stepless speed change. This transmission 100 is enclosed in the stub case 40, a closed sleeve cover 67. Inside the transmission 100 has three or more controllers 1A, 1B, 1C power, which have a spherical shape and are located at equal distances from each other circumferentially around the Central line or axis of rotation of the transmission 100. As more clearly seen from figure 2, the shafts 3A, 3b, 3C inserted in the center of the controllers 1A, 1B, 1C power to determine the axis of rotation for regulators 1A, 1B, 1C power. In figure 1 the axis of rotation of the power controller shown in the horizontal direction. The holders 2A-2E shaft attached perpendicularly to the shafts 3A, 3b, 3C at their ends. In one embodiment of each of the holders of the shaft has a hole for receiving one end of one of the shafts 3A, 3b, 3C. The shafts 3A, 3b, 3C also have rollers 4A-4E shafts located coax the material and slidable on the open ends of the shafts 3A, 3b, 3C outside holders 2a-2e shafts. As the axis of rotation of the controllers 1A, 1B, 1C power changes due to the tilt shafts 3A, 3b, 3C, each of the rollers 4A-4E shaft is held in a groove 6A-6E, carved into the stationary base 5A, 5B. In figures 1 and 3 stationary base 5A, 5B generally have the form of parallel disks with the axis of rotation passing through the center line of the transmission 100. The grooves 6A-6E are from the outer circumference of the stationary bases 5A, 5B in the direction of the Central line of the transmission 100. While the sides of the grooves 6A-6E are practically parallel, the bottom surface of the grooves 6A-6E forms a decreasing radius in passing toward the Central line of the transmission 100. As the transmission 100 is shifted to a lower or higher gear by changing the axes of rotation of the controllers 1A, 1B, 1C, each pair of rollers 4A-4E shafts, located on one of the shafts 3A, 3b, 3C, moving in the opposite direction along the corresponding groove 6A-6E.

In figures 1 and 3 the Central hole 7a, 7b in stationary bases 5A, 5B allows you to enter the hollow shaft 10 through both the stationary base 5A, 5B. In figure 4, in one embodiment of the invention, one or more of the holes 7a, 7b stationary bases may have feasibility form 14, which coincides with nationalcommittee 15 of the hollow shaft 10, to prevent rotation of the stationary bases 5A, 5B relative to the hollow shaft 10. If the hardness of the stationary bases 5A, 5B insufficient, can be used for additional construction to prevent any relative rotation or bending the stationary bases 5A, 5B. This kind of movement stationary bases 5A, 5B may cause the clamping rollers 4A-4E shafts during their movement along the slots 6A-6E.

As shown in figure 4 and 7, this additional structure may be in the form of spacers 8A, 8b, 8C, fixed between the stationary bases 5A, 5B. Spacers 8A, 8b, 8C add rigidity between the stationary bases 5A, and 5B, in one of the embodiments, are located close to the outer circumference of the stationary bases 5A, 5B. In one embodiment of the stationary base 5A, 5B connected to the spacers 8A, 8b, 8C by means of bolts or other fastening devices 45A-e inserted through holes 46a-e in stationary bases 5A, 5B.

Figures 1 and 3 stationary base 5A is rigidly attached to the sleeve 42 fixed base, which coaxially encloses the hollow shaft 10 and extends through the wall of the sleeve body 40. End of the coupling 42 of the stationary base, which passes through the wall of the sleeve body 40, is attached to the frame and preferably has the feasibility of the forms is to simplify the subsequent mounting of the rotary lever 43. As more clearly shown nafig, the rotary lever 43 is placed on a feasibility form the end of the clutch 42 of the stationary base and is held in place by the rotary nut 44. The rotary lever 43 to its second end rigidly attached to a solid stationary parts such as the frame (not shown). The bearing 48 fixed base supports the stub case 40 and allows the stub to the housing 40 to rotate relative to the clutch 42 of the stationary base.

Figures 1 and 2 shift is manually activated by an axial sliding of the rod 11, which is located in the hollow shaft 10. One or more pins 12 inserted through one or more vertical holes in the rod 11 and pass then through one or more longitudinal slits 16 (not shown) in the hollow shaft 10. The slots 16 in the hollow shaft 10 to provide axial movement of the connected pin 12 and the rod 11 in the hollow shaft 10. When the rod 11 is shifted along the axis of the hollow shaft 10, the ends of the vertical posts 12 are coaxial coupling 19 and go with it. The clutch 19 is rigidly attached at each end to almost a flat platform 13A, 13B forming the sole around the clutch 19.

As more clearly seen in figure 4, each of the flat platforms 13A, 136 in contact with several wheels 21A-e and pushes them. Wheels 21A-e enter the slots in the holders 2A-2E shaft and hold the season in place of the wheel axes 22A-22E. Wheel axis 22A-22E at their ends are supported by the holders 2A-2E shafts and provide rotational movement of the wheels 21A-e.

Figures 1 and 2 almost flat platform 13A, 13B become convex surface on its outer perimeter (at the greatest distance from the hollow shaft 10). This site allows you to eliminate the gap with the slope of the holders 2A-2E shafts and regulators 1A, 1B, 1C power when shifting the transmission 100. A cylindrical supporting element 18 is located in the base, is formed between the flat platforms 13A, 13B and the clutch 19, and thus moves together with flat platforms 13A, 13B and the clutch 19. Supporting element 18 rides on the contact bearings 17A, 17B, located at the intersection of the flat platforms 13A, 13B and couplings 19, allowing the support element 18 to rotate freely around the axis of the transmission 100. Thus, the bearings 17A, 17B, the support element 18 and the sleeve 19 are shifted along the axis with the flat platforms 13A, 13B when shifting the transmission 100.

Figure 3 and 4 rollers 30A-30e stationary base pairs attached to each arm 2A-2E of the shaft through the roller pin 31A-31E and held in place by roller clamps 32A-e. Roller pins 31A-31E allow the rollers 30A-30e stationary base to rotate freely around the roller pins 31A-31E. The rollers 30A-30e stationary base roll povorotom the radius of the stationary base 5A, 5B along a path almost parallel to the grooves 6A-6E. When the rollers 4A-4E shaft move back and forth within the slots 6A-6E, the rollers 30A-30e stationary base does not permit either the ends of the shafts 3A, 3b, 3C, or rollers 4A-4E shaft to come into contact with the bottom surface of the grooves 6A-6E, supporting the position of the shafts 3A, 3b, 3C and minimizing any functional loss.

Figure 4 shows the rollers 30A-30e stationary base, the roller pins 31A-31E and roller clamps 32A-e looking through the stationary base 5A for easy viewing. For clarity, that is, as figure 1 contains too many digital signs, rollers 30A-30e stationary base, the roller pins 31A-31E and roller clamps 32A-e not numbered in figure 1.

Figures 1 and 5 concave disk drive 34, located adjacent to the stationary base 5B, partially cover the stationary base 5B, but not in contact with him. The drive disk 34 is rigidly attached through its center to the screw 35. The screw 35 coaxial hollow shaft 10 and forms around him clutch connecting with the stationary base 5B, and turned to the drive element 69. The drive disk 34 is connected to the controllers 1A, 1B, 1C power for rotation along a circular bearing surface on the protrusion of the drive disk 34. Nut 37 is screwed on the screw 35 and is rigidly prigodjatsja on its circumference to support the claim of 60. One end of the nut 37 is additionally attached to the drive element 69. Also to the surface of the supporting disc 60 is firmly fixed many of the guides 61 from the drive disk 34. For each rail 61 there is one bearing guide 62, held in place bearing cage 63. The bearings 62 of the guide in contact with the guides 61 and the drive disk 34. Spring 65 attached at one end to the bearing cage 63 and at the other end to the drive disk 34, or the supporting disc 60 in an alternate implementation, to offset bearings 62 guides from the guides 61. The supporting disk 60 on the side opposite the guide rails 61, and at approximately the same circumference in contact with the bearing 66 of the sleeve cap. The bearing 66 of the sleeve cap is in contact with the stub cap 67 and the supporting disk 60, providing relative movement. The stub cap 67 is screwed or shrinked in the stub case 40 and is fixed with the aid of the inner ring 68. Chain sprocket or pulley 38 is rigidly attached to a rotating drive element 69 and is held in place on the outside by means of a conical bearing 70, fixed conical nut 71, and from the inside through the drive bearing 72 which is in contact with the driving element 69 and liners is offered by the lid 67.

When working the incoming rotation of the chain sprocket or pulley which is rigidly attached to the drive element 69, rotates the supporting disk 60 and many of the guides 61, causing the bearings 62 guide to roll along the guide rails 61 and press the drive disc 34 to the controllers 1A, 1B, 1C power. At the same time the nut 37, which has a smaller step than the guides 61, rotates, causing the connecting screw 35 and nut 37. Thus the screw can be made left-handed, and the reference disk to rotate clockwise. The screw can also be done right, and the reference disk to rotate in a counterclockwise direction. This property gives the drive disk 34 to rotate against the controllers 1A, 1B, 1C power. Regulators 1A, 1B, 1C power while rotating in contact with the stub case 40 and rotate it.

Upon termination of rotation of the support disk power regulators rotate the screw 35 or the nut 37, which is rigidly attached to the rotating drive element in the direction from the power regulators, thereby decoupling the transmission.

When the transmission 100 is moving by inertia, chain sprocket or pulley 38 stops spinning, but the stub case 40 and the controllers 1A, 1B, 1C continue to rotate. This leads to the fact that the drive disk 34 is rotated so that the screw 35 is screwed into the nut 37 as long as the drive dis is 34 is no longer in contact with regulators 1A, 1B, 1C.

In figures 1, 6 and 7, the coil spring 80, coaxial with the transmission 100, is located between the supporting disk 60 and the drive disk 34, and its ends are attached by pins or other fasteners as the supporting disc 60, and the drive disk 34. During the transmission 100 of the spiral spring 80 provides communication between the controllers 1A, 1B, 1C power and the drive disk 34. Supporting element 83 of the pawl includes a helical spring 80 so that its secondary coil is attached to the support element 83 of the pawl pin or standard fasteners (not shown). Since the supporting element 83 of the pawl is attached to the middle coil of the coil spring 80, it rotates at a speed equal to half the speed of the drive disk 34 when the supporting disk 60 is not rotating. This allows one or more locking dogs a, 81B, V, attached to a supporting element 83 dogs one or more pins a, b, V, coupled with the ratchet 82 to the disk drive, which is coaxial drive disk 34 and is rigidly attached thereto. One or more locking dogs a, 81B, 81 preferably are arranged asymmetrically around the ratchet 82 to the disk drive. When the clutch is prevented from pushing the compressed spiral spring 80 to the disk drive 34 in the direction of the controllers 1A, 1B, 1C power. Thus, in the absence of contact is and drive disc 34 with regulators 1A, 1B, 1C power transmission 100 is in the neutral position and increases the ease of switching. Transmission 100 can also be switched during operation.

When the action of the transmission 100 is resumed by turning the chain sprocket or pulley 38, one or more releasing dogs 85a, 85B, 85C, each of which is attached to one of the locking dogs a, 81B, V pin a, 88B, V dogs, comes in contact with the opposite ratchet 87 of the supporting disc. The ratchet 87 of the supporting disc coaxial supporting disc 60 and is rigidly attached thereto. The ratchet 87 of the supporting disc actuates the releasing dogs 85a, 85B, 85C, because releasing dogs 85a, 85B, 85C are connected with the supporting member 83 dogs through the catches e, 81B, W. Under the action of releasing the dogs 85a, 85B, 85C rotate at a speed equal to half the speed of the supporting disc 60 as the drive disk 34 is not rotating, and disconnect the catches e, 81B, V from the ratchet 82 to the disk drive, allowing the spiral spring 80 to rotate the drive disk in the direction of the controllers 1A, 1B, 1C power. One or more tensioning devices (not shown) dogs, one for each releasing dogs 85a, 85B, 85C, ensures that the catches e, 81B, W is pressed against the ratchet 82 to the disk drive, and that releases from the tanks 85a, 85B, 85C is pressed against the ratchet 87 of the supporting disc. Tensioner dogs are attached at one end to a supporting element 83 of the pawl and at the other end in contact with the releasing dogs 85a, 85B, 85C. Assembly hole 93 (not shown) in the sleeve cap 67, the supporting disk 60 and the drive disk 34 allows you to insert the Assembly pin (not shown) in the compressed helical spring 80 during Assembly of the transmission 100. Assembly pin prevents the loss of the spiral spring 80 to its compression and is removed after Assembly of the transmission 100.

In figure 1, 11, 12, and 15 automatic switching of the transmission 100 is performed through the cables 602, 604, 606 shaft, which is attached one end to a stationary component of the transmission 100, such as a hollow shaft 10 or the stationary base 5A. Then the cables 602, 604, 606 shafts pass around pulleys 630, 632, 634 shafts, which are arranged coaxially on the shafts 3A, 3b, 3C. Cables 602, 604, 606 shafts additionally pass around pulleys 636, 638, 640, 644, 646, 648 spacers that are attached to the extension 642 spacers, which may be rigidly attached to the spacers 8A, 8b, 8C. As more clearly shown at 11 and 12, the other ends of the cables 602, 604, 606 shafts are attached to many holes 620, 622, 624 in the non-rotating annular track 816 rolling bearing. Many load cables 532, 534, 536 attached one to the CMA to many holes 610, 612, 614 in a rotating annular track 806 rolling bearing. The annular bearing 808, located between the rotating annular track 806 rolling bearing and non-rotating annular track 816 rolling bearing, ensures their movement relative to each other.

On Fig shows the transmission 100 with padded rope for automatic switching.

As shown in figures 1, 9, 11 and 12, the load cables 532, 534, 536 are then passed around the pulley 654, 656, 658 sleeve housing, through the holes in the stub case 40 and hollow spokes 504, 506, 508 (best seen on Fig), where they are attached to the cargo 526, 528, 530. Cargo 526 528, 530 are attached to the holders 516, 518, 520 cargo and are supported by these holders of goods, which are attached to the wheel 514 or other rotating object at its opposite end. When the wheel 514 increases the speed, cargo 526, 528, 530 are drawn radially from the stub of the housing 40, pulling the rotating annular track 806 rolling bearing and non-rotating annular track 816 rolling bearing in the direction of the stub cap 67. Non-rotating annular track 816 rolling bearing pulls the cables 602, 604, 606 rollers, which pull the pulleys 630, 632, 634 shafts closer to the hollow shaft 10, which leads to the switching of the transmission 100 to a higher gear. When the wheel 54 is slowed down, one or more elastic elements 9 located inside the hollow shaft 10 and held in place by a cover 92 of the shaft, push the pulley 630, 632, 634 shaft farther from the hollow shaft 10, which leads to the switching of the transmission 100 to a lower gear.

Alternative or in combination with the elastic element 9 to the shafts 3A, 3b, 3C opposite pulleys 630, 632, 634 shafts can be attached with multiple elastic elements (not shown).

Figure 1 transmission 100 can also switch manually suppressing the automatic switching mechanism or replacing the automatic switching mechanism. Rotary switch 50 has an internal thread, screw-on external screw threads 52 of the switch, which is mounted on the hollow shaft 10. The switch 50 includes a cover 53 with a hole, which is placed on the rod 11, is inserted in the hollow shaft 10. The rod 11 is threaded in the place where it emerges from the hollow shaft 10, so that the rod 11 can start the nuts 54, 55. Nuts 54, 55 are placed on both sides of the cover 53. The lever switch 56 is rigidly attached to the switch 50 and provides a leverage point for the rod 11. The cable 51 of the switch attached to the arm 56 of the switch through the lever slot 57a, b, 57b. Several lever slots 57a, b, 57b are provided for varying the speed and ease of switching.

the and 1 and 10, the cable 51 of the switch goes to the handle 300 and coaxially wound on it. When the handle 300 is rotated in the first direction, the switch 50 is screwed or fastened in the axial direction of the hollow shaft 10 and pushes or pulls the rod 11 in the hollow shaft 10 or the hollow shaft 10. During the rotation of the handle 300 in the second direction, the spring 58 of the switch, which is located coaxially on the switch 50, returns the switch 50 to its original position. The ends of the springs 58 of the switch attached to the switch 50 and to a stationary component, such as a frame (not shown).

As more clearly seen in figure 10, the handle 300 is located on the Bicycle handlebar. (not shown) or other rigid component. The handle 300 includes rotating the handle 302, which consists of mounting 304 cable provided for attaching the rope 51 of the switch, and groove 306, allowing the rope 51 of the switch to gather around rotating the handle 302. It is also envisaged flange 308 so that the user does not interfere with the passage of the rope 51 of the switch. The teeth 310 of the ratchet handles are located on rotating the handle 302 in place of its connection with rotating clip 314. The teeth 310 of the ratchet handle interlock with the opposite set of teeth 312 of the ratchet clamp, when rotating the handle 302 is rotated in the first direction. Thus the teeth of the rotating ratchet arm look in the first direction, and the teeth of the ratchet in the of sausages clip look in the second direction. The teeth 312 of the ratchet clamp form a ring and are attached to the rotating clamp 314, which rotates together with a rotating handle 302, when the teeth 310 of the ratchet handle and the teeth 312 of the ratchet clamp coupled. The power required for rotating the clamp 314 may be adjusted by means of screw 316 or other fastening. When rotating the handle 302 is rotated in the second direction, the teeth 310 of the ratchet handle and the teeth 312 of the ratchet clamp reteplase. Thus, the rotation of the rotating arm in the first direction rotates the rotating clamp and rotating the handle in a second opposite direction does not rotate the rotating clamp. Figure 1 is a compression spring 5 switch increases when rotating the handle 302 is rotated in the second direction. Non-rotating clamp 318 and the non-rotating handle 320 to prevent excessive axial displacement of the handle 300.

On Fig and 14 reveals one perform powertrain 900. For simplicity, we discuss only the differences between 900 transmission from the transmission 100.

Rotating the stub case 40 replaces the fixed housing 901 and the housing 902, which are connected to one or more set screws 903, 904, 905. The set screws 903, 904, 905 can be removed, providing access for repair of the transmission 900. And the housing 901 and the housing 902 are located in the same plane as the flanges 906, 907, with many Bo is starting holes 908, 910, 912, 914 to insert the set screws 918, 920, 922, 924 hard for mounting transmission 900 to a stationary component, such as a frame (not shown).

Extension 930 spacers clamped between the stationary housing 901 and the housing 902 using the installation screws 903, 904, 905 and passes in the direction of the sleeves 8A, 8b, 8C and rigidly attached thereto. This extension 930 spacers prevents rotation of the stationary bases 5A, 5B. Stationary base 5A does not contain couplings 42 stationary base, as it was the transmission 100. Stationary base 5A, 5B hold the hollow shaft 10 in a fixed position. The hollow shaft 10 terminates at one end in a stationary base 5A and the other end of the screw 35. The output drive disk 942 added and held relative to the housing 901 pressurized bearing 944.
