    This invention relates to mechanical engineering. Vt can be used in disc brakes for automotive vehicles.
    The aim of the invention is to improve performance by preventing the elastic deformation of the floating bracket.
    FIG. 1-4 shows a self-adjusting disc brake.
    The disk brake (Figures 1 and 2) comprises a movable floating bracket 1 movably mounted on a fixed support 2 by means of at least one axial protrusion, for example, two columns 3 and 4, running parallel to the axis of rotation of the rotating disk 5. Axial columns 3 and 4, the brackets 1 located in the holes 6 and connected with it by the pins 7, pass through the holes 8 formed in the fixed support 2 and can move relative to the holes 8 and, consequently, relative to the fixed support 2. The first friction element 9 is located in hole 10, made in a stationary support 2. Hole 10 provides for mounting and sliding of the friction element 9. The second friction element 11 is mounted on the bracket 1 by means of two screws 12, connecting the friction element 11 with the bracket 1. In addition, the bracket 1 is equipped with a brake actuator 13 containing a hydraulic drive, as well as a mechanical drive (figure 2). The hydraulic actuator is equipped with a piston 14 of the hydraulic actuator movably mounted in the bore 15 formed in the brake actuator 13. The tightness between the piston 14 and the bore 15 is achieved by sealing 16, in addition, the piston 1 is protected by a piston cap 17. The piston 14 and the wall 18 of the base of the hole 15 define a chamber connected to a pressure source (not shown), for example, to a car master cylinder.
    A mechanical drive is provided by a lever 19 connected to a cable or similar device (not shown) and to an axis 20, in which a recess 21 is provided, receiving an elongated lead 22. An axle 20 and an elongated lead 22 are located in a blind hole 23 formed in the brake actuator 13 , and on the open area of the hole 23 is provided a threaded plug 24 (in the present embodiment). In the holes 23 there is also a pusher 25, at the end of which on the side of the axis 20 there is a recess 26, which interacts with the driver 22. The pusher 25, the hole 23 and the wall
     18 limit the intermediate chamber 27 in which the automatic adjustment device 28 is placed. The device 28 comprises a screw 29 with a running thread, on
    which has a nut 30, having at its end opposite the wall 18, a cone section 31, which interacts with a cone section 32 on the push rod 25. The screw 29 comprises a cylindrical section
    0 33 in which an annular recess is formed containing a seal 34. The seal 34 and the cylindrical portion 33 can be moved relative to the hollow annular
    5, a piston 35 mounted in a bore 36 in a wall 18. A seal 37 is installed in a bore 36 in order to ensure tightness with the possible movement of a piston 35 relative to the bore 37.
    0 The continuation of the cylindrical section 33 in the direction of the piston 14 is the threaded section 38, which provides the connection of the screw 29 with the driving piston 14. At the level of the conical section 31, the nut 30 has
    5, a rolling friction surface 39 facing the wall 18. The surface 39 is arranged to interact with the axial thrust ball bearing 40 located opposite the annular
    0 of the element 41 forming the second rolling surface. The element 41 can be moved in the opening 23 of the brake actuator 13. The annular element 41 is pressed against the end 42 of the pusher 25 by means of a return spring 43, which in turn rests on an annular part 44 integrated with the brake actuator 13. With the stop of the annular element 41 at the end 42 and the abutment of the tapered portion 31 to the tapered portion of the drain 32 between the ball bearing 40 and the annular element 41, a gap remains in order to limit the working gap of the brake. On the outer surface of the end of the nut 30, closest to the wall 18, there is a set of 5 grooves 45, in which there are protrusions 46.
    0 In its outer diameter, the sleeve 47 is guided by the hole section 23, whereby the sleeve 47 can move or rotate relative to the brake actuator 13. An annular rim 48, 5 mounted on the locking piston 35, is placed between the wall 18 and the front surface 49 of the sleeve 47 in an inoperative state When the bezel 48 rests on the wall 18, there is a gap between the sleeve 47 and the ring part 44. At the end of the locking piston 35 facing the chamber 50, there is an expanded portion or annular rim 51 integral with the piston 35. Between the rim 51 and the wall 18 there is a locking spring 52. in turn abutted against the wall 18.
    The brake actuator 13 includes a manual device 53 for zeroing the self-adjusting device. The device 53 contains a control rod 54, at the end 55 of which there is a gear 56, which interacts with a gear 57, located at the adjacent end of the nut 30. At the other end the control rod 54 has a control head that allows it to rotate using, for example, screwdrivers. The control head has a juice on which the return spring 59 rests. In turn, it rests on the pusher 25. Access to the rod 54 is provided by a threaded plug 59 screwed into the brake actuator 13. Since the rod 54 is movable with the pusher 25, it is provided a significant axial clearance between the rod 54 and the side walls of the hole 60, intended to access the rod 54 and install the plug 59.
    The two tapered surfaces 31 and 32 can be replaced by any other coupling. The working clearance of the brake can be placed at the level of communication between the screw 29 and the drive piston 14, when the ball bearing 40 is mounted without clearance between its rolling surfaces, and the end 42 of the pusher 25 may be missing.
    FIG. 3 and 4, a second embodiment of the invention is shown, the difference of which is the arrangement of the return to zero device 53, which in this embodiment interacts not with the nut 30, as in the first embodiment, but with the sleeve 47, on which the second gear 57 and which rotation of the nut 30 through the notches 45 and the protrusions 46. Remaining with the part of the brake actuator 13 is similar to the first embodiment.
    Due to seals 34 and 37, the intermediate chamber 27 is not affected by the hydraulic braking pressure that can be created in the chamber 50, and the hydraulic braking pressure also does not affect the zeroing device 53.
    The display of the nullification device 53 is as follows.
    After removing the plug 59 with a screwdriver, a force is applied to the rod 54 against the action of the return spring 58 so that the gear 56 of the rod 54 interacts with the clip 57 on the nut 30 for the first embodiment or on the sleeve 47 for the second variant. The rotation of the screwdriver and, therefore, the rod 54 causes the nut 30 to rotate directly in the first embodiment of the structure and through the sleeve 47 in the second embodiment, which ensures relative movement between the screw 29 and the nut 30,
    allowing you to bring to zero the device 28 automatic adjustment and. therefore, return the piston 14 to its original position.
    The return spring 58 of the rod 54 provides the disengagement of the gears 56 and 57 and makes it possible to eliminate their influence on the normal operation of the automatic regulation. To prevent contamination from the outside provided
