The technical field to which the invention relates.

The present invention relates to brake mechanisms used, for example, on the axles of commercial vehicles or trailers, namely, the automatic brake rattles, which prevent excess movement of the mechanism. brake used for braking.

The level of technology

During operation of the brake linings of the brake mechanism, such as a drum brake with pneumatic actuator used on the axles of commercial vehicles, as wear of the friction linings of the brake clearance between the brake pads and their respective friction surfaces (e.g., the inner surface of the brake drum increases. Such an increase of the gap requires increasing the range of movement of the brake actuator that moves the friction from their original positions to the place where the pads come into contact with a friction surface.

In recent times it has become common to include an automatic brake rattle in the mechanical path between the brake actuator and the brake pads to prevent excessive backlash when moving pads as brake lining wear. These rattles are usually located on part of the deceleration is tion of the Cam shaft, which is on the outside of the brake mechanism (usually secured by splines to the Cam shaft); associated with the plunger of the brake actuator so that when the plunger of the brake actuator is extended or retracted, the brake ratchet is rotated around the longitudinal axis of the brake Cam shaft. Thus, by extending or lowering of the pusher brake brake ratchet causes the brake Cam shaft to rotate around its longitudinal axis, which in turn rotates the Cam brake actuator, attached to the end of the brake Cam shaft located in the drum brake mechanism. When turning the Cam brake pads or pressed, entering into engagement with the inner friction surface of the brake drum or depart radially inward, away from the friction surface. Since the brake Cam shaft is used to rotate the Cam, which presses the brake pads radially outward of the brake Cam shaft also known as the brake camshaft.

Automatic slack Adjuster is usually designed to transfer forces from the brake to the brake Cam shaft in the direction of movement of the brake mechanism, without moving the ratchet relative brake Cam is on the shaft. After terminating the application of force to the brake actuator, if the distance between the brake pad and the friction surface of the brake drum is more correct, the brake ratchet may be rotated relative to the brake Cam shaft at an angular distance sufficient to prevent all or part of such unwanted backlash, i.e. decreasing the distance that the brake pad moves away from the friction surface of the brake drum, so that the gap between the plate and the drum was maintained at the required minimum distance.

In many automatic brake ratchets for the implementation of rotational adjustment movement is a one-way clutch and the worm shaft located in the ratchet rotates a worm gear coupled with a brake Cam shaft. When retracting the plunger of the brake actuator worm shaft is rotated around its longitudinal axis, causing the worm shaft and a worm gear to move relative to each other in the circumferential direction around the circumference of the worm gear. Such relative movement of the worm shaft and the transmission creates a corresponding relative movement between the casing brake Adjuster and the brake Cam shaft. As a result, when the plunger is Almaznogo actuator returns to its original position, brake Cam shaft to its original position will not be refunded. Instead, brake Cam shaft only rotates through a small angle to a new position. Brake Cam, thus, stops in the appropriate new source position in which the brake pads are closer to the friction surface of the brake drum. Since the rotation of the slack Adjuster relative to the brake Cam shaft leads to decrease the clearance between the brake linings in the new home position, automatic brake ratchet compensates for wear of the brake linings.

A one-way clutch used in such an automatic brake rattle is usually one of the following devices: spring overrunning clutch mounted on the inner diameter of the ratchet, and spring is moved in the direction of unwinding (an example is the model AA1 company Haldex Commercial Vehicle Systems, Kansas city, Missouri or model SB7 firm Swedish Brake Technology, Landscrona, Sweden); spring overrunning clutch mounted on the outer diameter, the spring is moved in the direction of the curl (an example is the model of the brake ratchet ASA-5®offered by the company Bendix Spicer Foundation Brake LLC, Elyria, Ohio), or saw-tooth gear coupling mounted t is thus, that sawtooth teeth engages with a corresponding toothed surface in the same direction and repel each other, clawing across in the other direction. The latter construction is preferred, since it is hard to transfer instead of friction used in the devices of the spring-overrunning type. In the automatic brake ratchets with saw-tooth gear couplings saw-tooth gear couplings are usually located coaxially with the worm shaft of the ratchet (for example, as it offers a firm Madras Engineering Industries of India), or coaxial screw ratchet (an example is the design used in the model S-ABA company Haldex Commercial Vehicle Systems, Kansas city, Missouri).

The lack of a rattle spring overrunning clutches, in particular with spring overrunning clutches for the inside diameter, is the use of frictional engagement, which may lead to arbitrary periodic slippage before engagement. In the end, to ensure reliable adjustments they require the use of expensive lubricants (i.e. expensive high-performance special lubricants). The previously mentioned saw-tooth gear couplings are usually more complicated and expensive to produce.

In view of the foregoing, the purpose of this is to Soberania is to offer improved brake ratchet, in which the one-way clutch built inside the mounting device of the ratchet so that it can reduce cost and simplify its manufacture.

Disclosure of inventions

To achieve these and other objectives and solve problems existing in the current prior art, the present invention proposes a construction in which the sawtooth gear clutch built inside support device or mounting device, automatic slack Adjuster, which is built into the side cover of the casing of the automatic slack Adjuster. In fact, the reference gear device is divided into two parts with pinched against axial displacement, which allows the use of construction gear couplings with radial engagement. This innovative arrangement also allows finer adjustment of the backlash due to the use of a larger number of teeth on the mounting plate, thereby providing a more precise, accurate and consistent movement of the brake Cam shaft for angular movement of the brake ratchet. This design also allows us to simplify its manufacture, since the production of saw-tooth gear couplings can be ideally added to the existing rolling production, that reduces the cost of manufacture, since the teeth are located on the inner diameter of the element mounting device in the position in which they can be bored with a lower cost. In addition, the teeth of gear couplings previous structures were located on the surface of the wheel, which had to be cut by milling or similar treatments. This version significantly improves the transmission of torque to overcome the friction between the worm gear and the casing rattles, which is the main factor affecting the performance of the ratchet. This further reduces the costs due to the use of lubricants, which are less costly compared to the previously used lubricants with a low coefficient of friction.

In a preferred variant implementation of the present invention the reference gear is divided into two parts with pinched against axial movement, thereby allowing coupling with radial engagement.

The improvements of the present invention will become more clear in comparison with examples of brake rattles from the prior art. For example, in U.S. patent No. 4,621,714 serves brake ratchet with a swivel coupling and opposing teeth, in which the clutch is engaged with what obami on an adjustment element, and due to the shape of the teeth, it can be rotated only counterclockwise. However, the performance of the engagement gear couplings is external, the screw ratchet, and not inside the main gear on the anchor finger, as in the present invention.

In U.S. patent No. 7,198,138 offers worm gear with built-in drum ratchet for the implementation of the one-way clutch. The present invention can further optimize production and to make more fine adjustments by embedding the coupling part of the anchor finger, and not in a worm gear.

In U.S. patent No. 3,444,758 serves brake ratchet, in which the worm gear and the teeth of the worm gear has an asymmetrical profile. Such profiles do not allow significant braking effort rasklinivat worm gear and the worm gear from each other. The gearing is on the outside of the gear, and not internal, as in the present invention.

In U.S. patent No. 3,901,357 an automatic brake ratchet adjustment which can also be operated manually from the outer side due to the location of the springs. The present invention does not provide for access to the clutch for manual adjustments.

In U.S. patent No. 4,561,523 an automatic brake is knowing rattle, which includes rescriptus cuff and an adjusting shaft, which allows the brake ratchet to maintain the brake gap by increasing or decreasing the distance between the drum and lining. Unlike the present invention, the clutch is part of the mechanism of the screw ratchet.

In U.S. patent No. 4,718,522 an automatic brake ratchet one-way clutch in the form of spring overrunning clutch on the worm shaft. In the present invention the spring overrunning clutch is not used.

In U.S. patent No. US 2007/0012529 offered the part of gears in which the gears are made from ceramic material to improve iznosostoikosti characteristics, however, not disclosed none of adjusting structures of the present invention.

Other objectives, advantages and new features of the present invention will become apparent from the following detailed description of the invention together with the attached drawings.

In figures 5a-5d is shown in cross-section and detail views of part of the site one-way clutch automatic slack Adjuster of figure 1.

The implementation of the invention

Figure 1 shows a view in oblique projection gathered automatic slack Adjuster with a casing 1, a lever 2, the brake actuator, in which is inserted the end of the plunger of the brake actuator (not shown), as well as supporting shoulder 3, which is fastened on the axle of the vehicle by 4 feet, forming a fixed anchor point. Automatic brake ratchet includes a slotted hole 5, in which are inserted into corresponding slots of the brake Cam shaft (for ease of reference, not shown). Pictured automatic brake ratchet includes part 6 of the casing, which contains the worm shaft 7 and the adjusting device 8, shown in figure 4. The worm shaft 7 is engaged with a corresponding worm gear 9 (also referred to as worm), on the inner circumference of which are slots the CTE is participation 5. The adjusting device 8 and the worm shaft 7 together perform the function of an adjusting drive (also known from the prior art as self-drive), so that during the rotation of the worm shaft 7 rotates the worm gear 9 in the casing 1.

The node 10 one-way clutch according to the invention in this embodiment is shown in figure 2 separately from the casing 1. In figures 3 and 4 shows the image of a disassembled unit 10 one-way clutch, which includes a support shoulder 3, the annular seal 11 that is designed to prevent external contamination and leakage of grease from the automatic slack Adjuster, side plate 12, the gear 13 and a bracket, preferably in the form of a support ring 14, which is inserted and held pawl 15 one-way clutches, as well as their corresponding deflection of the spring 16. In this embodiment, three dogs 15 are located at equal intervals around the circumference of the support ring 14, however, the specialist in the art will understand that the number and spacing of the dogs can be different, if it will not impair the operation of one-way clutches. Preferably the dogs has two teeth so that they were linked to better gear and reinforced durable the feature structure.

Additional details of this variant implementation structures one-way clutch shown in figure 5. On figa shows the vertical projection of the node 10 one-way clutch, which is visible to the side plate 12 and the foot 4 of the support shoulder. On fig.5b shows a view in cross section along the line a-a, which is visible to the combination of the Assembly consisting of the support shoulder 3, the annular seal 11, side plates 12, the gear 13, the support ring 14, and the pawl 15 and the deflecting spring 16 located in the support ring 14. The support ring 14 and the support shoulder 3 in this embodiment are connected by welding along their mating circumference 18. After Assembly in this way the support ring 14 is held stationary at the supporting shoulder 3, and the gear 13 and the side plate 12 are clamped between the support ring and the shoulder. Meanwhile, the gear 13 can rotate freely on the support ring 14 as shown in figures 5c and 5d, the dog 15 is deflected relative to the unidirectional teeth 19 on the inner circumference of the gear 13, deflecting the springs 16 so that the gear can rotate freely in one direction but cannot rotate in the other direction.

After the Assembly 10 one-way clutch in the casing 1 gear 13 is engaged with the adjusting screw 17, which is located in the casing 1 transversely of prodol the second axis of the worm shaft 7. The adjusting screw 17 communicates with a corresponding screw thread on the adjusting device 8 so that when the plunger of the brake actuator acts on the automatic brake ratchet to rotate the brake Cam shaft and then returns to its original position, the pawl 15 one-way clutches allow the gear to rotate relative to the support shoulder in one direction, but is fixed with a gear 13 on the supporting ring 14 and the support arm 3 to prevent rotation of the pinion in the other direction. Thus, when pressing on the brake and turning the casing 1 relative to the supporting shoulder 3, the gear 13 can be rotated together with the casing 1, thereby not allowing the gear to rotate the adjusting screw 17 and the adjusting device 8 (the Executive, the spring inside the adjusting device 8 generates sufficient resistance from friction, prevents rotation of the device and the adjusting screw 17, thereby causing the pinion gear 13 to rotate on the supporting ring 14, as the housing 1 is rotated relative to the supporting shoulder 3).

In turn, when you release the brake pawl 15 is fixed with a gear 13 on the supporting ring 14 so that the gear does not move relative to the supporting shoulder 3. As a result, after returning automatically the brake ratchet to its original position (i.e. after the move, in which the casing 1 is rotated relative to the supporting shoulder 3), the adjusting screw 17 is rotated as it moves along the circumference of the fixed gear 13. When turning the adjusting screw 17, in turn, is turning the adjusting device 8, thereby removing excess backlash in brake mechanism, thereby reducing the number of movements necessary to the casing 1 for rotation of the brake Cam shaft and engagement of the brake mechanism. The advantage of the present invention is that the position of the dogs 15 and the internal gear teeth 13 allow the use of teeth with a very small step, this characteristic allows for fine adjustment. Preferably the number of teeth used in this design is 60.

SUBSTANCE: disk brake comprises disk-stabilising elements, which are installed between every brake disk and hub or part joined to hub, without fixation and are arranged and installed with the possibility of deviation in axial direction in process of braking and creation of force that provides for axial return of brake disks in case of brakes release. Disk-stabilising element may have rectangular shape mainly, with two long sides and two short sides, by means of which short sides are installed in gaps between teeth or splines in brake disk. Disk-stabilising element may have two free lower ends, which are engaged with top of two adjacent splines or teeth of braking disk, and one upper bent end, which is engaged with base between two adjacent splines or teeth of braking disk. Disk-stabilising element may include helical spring, which is installed in braking disk gap, therefore both ends of helical spring pass radially from helical spring in opposite directions and end with brackets. Disk-stabilising element may be made of metal sheet having shape of "П"-shaped double-sided contour element with two branches, which are joined by base.

EFFECT: improved technical characteristics of disk brake, elimination of noise and jamming and exclusion of disk incline, by means of its stabilisation with the help of disk-stabilising elements.
