     This invention relates to mechanical engineering and can be used in automobile disc brakes.
    The purpose of the invention is to improve performance by increasing maintainability and increasing the stiffness of the bracket.
    FIG. 1 shows a disc brake, side view; figure 2 is the same, top view; on fig.Z - section A - A in figure 1; 4 is the same embodiment; figure 5 - section B - B in figure 2; figure 6 - section b - b in figure 2; from Fig.7 - disc brake, side view; on Fig the same, top view; in Fig.9 section G - G in Fig.7.
    The disk brake (Figures 1 to 3) contains a fixed support 1 attached to the stationary part of the vehicle (not shown) consisting of a plate located in the area of the rotating brake disk pack 2 attached to the vehicle’s wheel (not shown) with the possibility of sharing with it rotates. The rotating disk pack 2 consists of two brake discs 3 and 4 connected respectively to the sliding hub 5 and to the stationary hub b, to which the hub 5 is connected with the possibility of joint rotation by means of a keyed joint 7. On the fixed support 1 by means of a fixed support in the form of two spaced apart from each other around the circumference, the axial rods 8 and 9 are slidably mounted movable bracket 10 covering the package. Rods 8 and 9 are parallel to the axis of rotation of the package 2 and are located in the holes 11 and 12 of the projections 13 and 14 of the bracket 10. The bracket 10 consists (2) of two crossbars 15 and 16 placed on both sides in the axial direction of the package 2 and connected between each other by means of two levers 17 and 18 located axially at a distance from one another circumferentially around the periphery of the package 2 with the formation between TpasapcaNiM 15 and 16 and the levers 17 and 18 of the radial window 19, in which they are installed with the possibility of sliding along the levers 17 and 18 friction elements 20 -23. placed on each side of the disks 3 and 4. The bracket 10 also contains a third lever 24 axially located on the outside of the window 19 and mounted rotatably around an axis. for example, bolt 25 on traverse 16 and rigidly fixed on traverse 15 by means of a rigid backlash-free connection 26. These means are made in the form of a radial surface located on the third lever 24 located on the opposite end of the bolt 25 of the third lever 24 2, interacting axially with a radial surface 27. A recess made at the cross-bar 15 by means of an eccentric assembly placed concentrically with the axis of rotation (bolt 25) The lever 24 also has a tangential surface 28, which interacts with the tangential p & 29 surface of the crosspiece 15 in the radial direction with the possibility of fixing by means of a threaded connection, namely a screw 30.
    5 An eccentric assembly mounted concentrically on the bolt 25. is made as mounted on the bolt 25 with a cylindrical surface 31 of the sleeve 32 with an eccentric bore 33, stationary
    0 connected to the bolt 25 in the direction of rotation by means of a key 34. installed in the canopy on the surface 31 and in the hole 33. With its outer cylindrical surface 35, the sleeve 32 is located 5 in the hole 36 of the third lever 24 on its
    end of 37. Bolt 25 enters surface 31 in
    holes 38, made in two ears 39.
    fixed to the traverse 16.
    In the specified version on the traverse 16
    0 is installed. A dual actuator 40. each part of which has an opening 41c with a piston 42 mounted therein with the possibility of sliding with the formation of a chamber 43. connected to a pressure source. For example a brake master cylinder (not shown).
    The third lever 24 may be provided with a flat spring 44. fixedly mounted on it by means of bent legs
    0 45 and having petals 46. squeezing friction elements 20 to 23 radially inward to ensure a snug fit to the levers 17 and 18. At the same time, tightening the screw 30 ensures
    5 preload on the flat spring 44 and. therefore, on friction elements 20 - 23.
    In the second embodiment (Fig.7-9), the movable bracket 10 consists of two traverse bars 15 and 16.
    0 connected to each other by means of levers 17 and 18. The latter are threaded rods attached by means of threaded elements 47 on one side to the traverse 15. and on the other to
    5 traverse 16. each of which passes through the holes 11 and 12 in parts 48 and 49 of the caliper 1. located above the periphery of the disks 3 and 4. Friction elements 20 - 23 are inserted between the parts 48 and 49 with the possibility of sliding over them (as shown in FIG. 7). The third lever 24 extends from the outer side of the window 19 and rigidly connects the two crossbars 15 and 16. The end of the lever 24 comprises a coupling device in the form of a protrusion 51 placed in the recess 52 Traverse 15. On the protrusion 51 and in the recess 52 radial 26 and 27 and tangential 28 and 29 surfaces interacting with one another. The second end 37 of the lever 24 comprises an eccentric assembly and a flat spring 44, similar to those described above.
    To eliminate the backlash, another system can be used (without an eccentric) applied to the first version of the brake (Fig. 1-3).
    The inner end 37 of the third lever 24 in this embodiment is mounted directly on the bolt 25, possibly using an intermediate coaxial sleeve (not shown), and the outer end 50 of the third lever is made with an inner bearing surface 53 located at an angle of less than 90 (for example, 80 °) to the axis of the package 2 and interacting, possibly by means of a wedge (not shown), with a corresponding inclined surface 54 of the crosspiece 15 of the bracket. At the same time, the indicated surfaces are brought into contact with one another by a screw 30, the excessive tightening of which ensures the creation of an axial preload acting on the bracket.
    As an option, it is possible to make the actuator 40 single separately from the crosspiece 16. The third lever 24 can be hinged on the crosspiece 15 and closed on the crosspiece 16.
    Levers 17 and 18 may be provided with corrugated covers 55 and 56 to protect the sliding surfaces.
    The brake in accordance with the first embodiment (FIGS. 1-6) is assembled as follows. First, mount the bracket 10 (without the third lever) on the caliper 1, and then freak-. Elements 20 - 32, radial installation is provided with a window-19. First install the friction element 20 between the actuator 40 and the primary disk 3, and then through the window 19 install the friction elements 21 and 22 between the disks 3 and 4. Lastly insert the friction element 23 between the disk 4 and the cross member 38. Then set the cross member between the lugs 39 16, the end 37 of the lever 24. A bolt 25 is passed through the apertures 38, so that the key 34 exactly fits into the groove of the bolt 25. Then put the nut (not shown) without tightening it. Assembled lever 24 throws on the traverse 25 so.
    so that its tangential surface 28 lies against the surface 29 of the crosspiece 15. By turning the head of the bolt 25, the sleeve 32 is rotated, which, due to eccentricity, makes contact of the radial surfaces 26 and 27, after which a small additional torque is applied to the eccentric to securely adhere the radial surfaces 26 and 27 After that, install the screw 30, which clamps the end 50 of the lever 24 in the required position relative to the crossbar 25. Then tighten the nut of the bolt 25 and fix it against rotation, fix it to 37 ec lever 24 in this position, providing a rigid connection between the third arm and the crosspiece 16.
    If it is necessary to remove the friction elements 20 - 23, it is only necessary to loosen the bolt 25, unscrew the screw 30 and, turning the lever 24 around the cylindrical part 31 of the sleeve 32, fold it back, providing access to the friction elements 20-23.
    The brake according to the second variant (FIGS. 5-9) is assembled as follows.
    First, the bracket 10 without the lever 24 is mounted on the fixed caliper 1. To do this, by means of the threaded elements 47, the arms 17 and 18 with the covers 55 are fixed in the crosspiece 15. Then the levers 17 and 16 are inserted into the holes 12 of the caliper 1, two other covers 56 and put on levers 17 and 18 traverse 16 with a power drive 40. Fasten the nuts on the threaded ends of the levers 17 and 18, then install the friction elements 20 - 23, insert them in the radial direction to the stop in parts 48 and 49 of the caliper 1 and set assembled in the form described above lever 24 with eccentric oic sleeve 32. The rotating it by a bolt 25, end 50 bias the lever 24 in the direction of arrow D (Figure 9), and a protrusion 51 opposite the recess 52 in the yoke 38.
    After this, the end 50 is lowered along arrow E (Fig. 9) and, turning the sleeve 32 in the opposite direction, displaces the end 50 of the lever 24 in the direction opposite to the arrow D, and inserts it into the recess 52, ensuring the contact of the radial 26 and 27 and tangential 28 and 29 of the surfaces of the end 50 and the lever 24 and the crossbar 15. An additional rotation of the bolt 25 and the preliminary loading of the spring 44 ensure reliable adhesion of the lever 24 to the crossbar 15 and then check the threaded connection. Remove the lever 24 in reverse order.
