    (54) MEXAHHSNf BRAKE REPAIRS FOR BRAKING
    I
    This invention relates to automotive brake systems.
    The closest to the inventive procedure known is the mechanism for adjusting the gap for the brake system, the content is fixed against rotation and the spacer, a threaded sleeve installed with the possibility of axial rotation, a housing part fixed against rotation, a ring with a friction surface and a spring, a bottom The sliding friction surface JQ of the ring to the friction surface, made on one naz teazan (s, details, the specified parts of the fur frame are set coaxially with each other and are connected between themselves by means of Hopping j5 and non-locking brakes 1.
    A disadvantage of the known mechanism lies in the complexity of the construction and axial axial size.
    The purpose of the invention is to simplify the design and reduce the axial size of the mechanism.
    This goal is achieved by the fact that the ring is installed on the threaded bushing, which in turn is placed on the threaded sleeve.
    flogged and connected to the last threaded connection.

    In addition, the threaded sleeve can be made with a friction surface in contact with the friction surface of the ring, can be made with a support surface pressed by an Additional spring to the bearing surface on the body part, with an additional spring located between the flanges of the thread sleeve and body part; an additional spring can be installed in the beaker separating it from the flange of the threaded sleeve, and the ring and the housing are interconnected by a non-self-braking thread, the thread connecting the threaded sleeve with a spacer is self-braking; The main body can be made in the form of a spring washer placed between the flange of the threaded hub and the cup; Moryi friction surfaces are conical; the friction surface of the ring may be formed on the inner part of it and can be performed on the outer part of it and contact with the friction surface, vito; ;; Noah - body 3 of the 7th part, and the thread connecting the ring with the threaded sleeve is made non-braking. FIG. Figure 1 shows the clearance adjustment mechanism incorporated in a piston hydraulic drive; in fig. 2 - clearance adjustment mechanism; in fig. 3 - the same, end view; in fig. 4 shows another embodiment of the mechanism; in fig. 5 - the same, end view; in fig. 6 - the third embodiment of the mechanism. According to the first embodiment (Fig. 1), the mechanism is mounted in a piston hydraulic drive consisting of a piston 1 and 2 and equipped with an auxiliary one. a drive including a cam 3 mounted in the piston 2 and connected through the pusher 4 to the spacer 5. The spacer 5 is connected to the clearance adjusting mechanism 6 and has an externally threaded thread 7 that mates an internal thread 8 of the threaded sleeve 9. Mechanism 6 has a housing part 10, which is pressed into the blind bore 11 of the piston 1. The adjustment mechanism 6, shown separately in FIG. 2 and 3, has a ring 12 with a MULTI-EXTERNAL external thread 13, which mates with a thread 14 inside the JO part. Threads 13 and 14 have a reverse direction with respect to screw connection 15 formed by threads 7 and 8 .. Ring 12 has a conical friction surface 16 in contact with a conical friction surface 17 on the flange 18 of the sleeve 9. On ring 12 there is a second conical surface 19 .The surfaces 1b and 17 are pressed against each other by a daibae 20. The supporting surface 21 on the flange 18 of the sleeve 9 contacts the supporting surface 22 of the ring 23 fixed in the component 10. An additional spring 24 is installed between the flange 25 and glass 26. The spring 24 has greater rigidity than the washer 20. Spacer 5 is sealed in piston 2 by ring 27 and fixed against rotation by plate 28. Connection 15 is self-braking, and connection 29 formed by threads 13 and 14 is self-braking. Compound 29 has an axial clearance,; determining the amount of normal brake travel. If there is wear on the brake pads, the stroke of pistons 1 and 2 exceeds the gap in joint 29. The pressure action between pistons 1 and 2 pushes the strut 5 to the right with the piston 2. As soon as the pistons 1 and 2 are consumed, the strut 5 pushes sleeve 9 to the right , overcoming the action of the spring 24. When the gap in the connection 29 is selected. The tulka 9 presses the ring 12 to the right of the extrusion part 10, causing it to rotate the joint 29, while the torque developing on the surfaces 16 and 17 is greater than the torque developed from the side of the flange 18 on the sleeve 9 by the force of the spring 24. the ring 12 rotates the sleeve 9 by adjusting the connection 15. When the pressure is relieved, the spring 24 pushes the sleeve 9 to the left until surfaces 21 and 22 are not aligned. The movement of sleeve 9 relative to part 10 tends to separate the surfaces 16 and 17. so what's the torque with their art the pitch becomes smaller than the moment that develops in the sleeve 9 under the action of the spring 24. The washer 20 pushes the ring 12 to the left, while the connection 29 rotates the ring 12 in the opposite direction, the spring 24 prevents the sleeve 9 from rotating, and the surfaces 16 and 17 slip relative to each other . As shown in FIG. . 4 and 5, connection 29 is between the ring 12 and the sleeve 9, the friction conical surface 16 is made on the outer side of the ring 12, and the friction conical surface 17 is made on the body part 10. The mechanism shown in FIG. 4 and 5 is similar to the operation of the mechanism shown in FIG. 1-3. According to FIG. 6, an adjustment mechanism 6 is mounted in a drum brake and is part of an assembly 30 operating between the upper ends of the pads. Node 30 has a spacer 5 with a thread 7, t forms a thread with a thread 8 in the sleeve 9, self-braking a connection 15. The housing part 10 is rigidly connected to the part. 31 of the node 30. The sleeve 9 has a thread 13, forming with the G4 thread a ring 12 non-braking connection 29. The direction of the threads of the connections 15 and 29 is the same. The ring 12 has a friction surface 16, and the part 10 has a friction surface 17. A return spring (not shown) presses the thrust washer 32 to the sleeve 9, which prevents the sleeve 9 from rotating by vibration. The spring washer 20 is located between the ring 12 and the ring 33. When the brake is applied, the strut 5 moves to the left relative to part 31 under the influence of the spring 24, the gap in the connection 29 is selected, the ring 12 rotates on the hub 9. When the brake is released, the strut 5 and part 31 move towards each other, the sleeve 9 rotates on the strut 5 and adjusts the clearance. Formula from. 1. The clearance adjustment mechanism for the brake system, comprising a spacer fixed from E-spacing, a threaded bushing mounted for axial rotation, a housing part fixed against rotation, a ring with a friction surface and a spring pressing the friction surface of the ring against the friction surface made at one of the specified parts, the specified parts of the mechanism are aligned with each other and are interconnected by means of self-braking and non-braking threads, differing So that, in order to simplify the design and reduce the axial size of the mechanism, said ring is mounted on a threaded bushing, which in turn is placed on a spacer and is associated with the last threaded connection.
