    1516519 Wear adjusting in disc brakes WABCO WESTINGHOUSE GmbH 28 Oct 1975 [28 Feb 1975] 44247/75 Heading F2E The length of a device interposed between the annular piston or cylinder and a brake ring of a disc brake is increased as the piston or cylinder stroke increases to compensate for wear. As shown, a floating fluid-pressure actuator located between two brake rings (Fig. 1, not shown) comprises a cylinder 16 and linked pistons 17 and 27. The latter is integral with a ring 33 whose end face consists of a series of oblique surfaces 36 (Fig. 3) co-operating with complementary surfaces 35 on a ring 34; springs 38 tend to relatively rotate the rings. Ring 34 abuts a thrust member 37 slidable relative to piston 27 but frictionally coupled thereto by spring 40. In operation piston 27, rings 33, 34 and member 37 initially move together along with a locking ring 42 engaged in an annular groove 43 in member 37. Excessive piston movement causes the locking ring to abut stops 46 and unseat from groove 43. The ring then frictionally restrains return movement of member 37 when the piston retracts, so that rings 33, 34 tend to separate and thus relatively rotate and increase their combined effective length. Locking ring 42 has a notched periphery 41, 41a and member 27 has complementary longitudinal grooves 45 which allow resetting of the member after rotating it relative to the groove.

    (54) DISK BRAKE
    The invention relates to vehicle braking systems. Disc brakes are known that are equipped with an automatic freewheel 1. In these brakes, brake pad wear is compensated by threading, which leads to an increase in the volume of the cavity between the force elements associated with the brake pads. Also known disc brake co. holding two annular elements moving progressively relative to each other under the action of pressure in the cavity between them. to the brake pads and equipped with an automatic freewheel adjuster 2. In this brake, it is impossible to ensure the disconnection of the pads from the brake discs with the brake inoperative. The proposed disc brake differs from the known ones in that the automatic regulator is made in the form of sequentially installed on the .Chimming ring, acting when moving the brake pads, and two adjusting rings, one of which is installed with the possibility of translational movement and turning in one direction. An annular element is also provided with a clamping device fixing it against rotation in the other direction, and the other is rigidly connected to the annular element along the end, and One to another ends of the adjusting ribs are sawn-shaped, wedged protrusions between which one or several springs are mounted, and on the other annular element are mounted with limited movement together with the pressure ring a clamping ring that frictionly acts on the latter in the opposite direction from the brake pads direction when moving the ring element. In addition, annular grooves are made on the inner surface of the pressure ring, the width of which is thicker than the thickness of the clamping ring and at least one axial groove, and on the outer surface of the clamping ring the protrusion responding to the specified axial groove. Such constructive performance of a brake provides improvement of its operational qualities. FIG. 1 shows a disc brake with a common annular piston and with a schematically depicted automatic regulator; in fig. 2 - the same, with separate
    annular pistons and a detailed depiction of an automatic regulator; in fig. 3 is an AA section of FIG. 2; in fig. 4- fixation knot for fixing ring against rotation; in fig. 5-section bb on fit. 2; in fig. 6-push and latch | MNO rings.
    On the axis. / Brakes installed on bearings 2 sleeve 3, which is fixed. 4 brake discs 5.
    The bracket 6 is mounted in the direction of rotation stationary and with the possibility of axial movement of the brake rings 7-8 with brake pads 9 and ilO.
    The brake drive (ICM. Fig. 1) consists of two annular elements: a cylinder 11 and a Porschn 12 installed in it, in which an automatic freewheel adjuster is placed. A cavity 13, in which a spring 14 can be installed, is connected by a pipe 16 with a brake valve 16 placed in the cabin of the car, and the cavity 17 is connected by a pipe. / 5 with handbrake valve J9.
    The brake actuator (see Fig. 2) may also contain an annular // cylinder, alone, in it. The Alternating pistons, / 2 and 30, connected by a sealed jumper 21, are movably installed. The cavity 22 is connected with a brake valve in the cab, the car hit, and the cavity with a 17-valve manual brake.
    The automatic freewheel adjuster includes a pressure ring 23, which acts when moving on the brake pads, and two adjustment rings 24 and 25. The adjustment ring 24 is connected to the ring face 20 at the end of the wedge and 1 is fixed with the possibility of translational movement and rotation in one .the direction relative to the piston 20 and provided (see FIG. 4) with a clamping device 26 securing it against rotation in the other direction. The end faces of the adjustment rings i24 and S6 facing one another are made of saw-tooth matching protrusions (see Fig. 3), between which one or several springs 27 are installed. The piston 20 is loaded relative to the cylinder 11 by a spring 28.
    The pressure ring 23 and the piston 20 - by means of the spring 29 are located in the friction link (see - Fig. 5).
    A clamping ring 30 and stops 31 are installed on the annular cylinder Ы, limiting the axial movement of the latter together with the pressure ring 23 during normal braking. On the inner surface of the pressure ring 23 are annular grooves 32 and 33, the width of which is greater than the thickness of the clamping
    rings 30, and axial grooves 34. On the outer surface of the clamping ring 30, protrusions 35 are made (FIG. 6).
    To receive a special tool 36 Serves groove 37 of the adjusting ring 25.
    Brake (see fit. 1) works as follows.
    When ib is applied, the braking action
    the valve 16 in the cabin of the car in the cavity 13 creates pressure, which on one side presses the annular piston 12 with the brake ring 8 and the brake pad 10 K rotating brake disk.
    5 and, on the other hand, an annular cylinder // and with a brake ring. M and a brake disc 9 - to a rotating brake disc 4. When the manual brake valve is actuated, the air is released
    from the cavity 17, with the cylinder // and the piston 12 moving apart by the spring 14.
    The brake (see Fig. 2) operates similarly when pressure is applied from the brake valve to cavity 22 and the pressure is released.
    with the help of the brake valve from the cavity 17.
    When moving to the left ring
    piston 20, i.e. when the brake is activated,
    last through adjustment rings 24
    and: 25 acts on the pressure ring 23, moving it towards the brake pad, and with it the clamping ring 30. If the piston 20 exceeds a certain stroke due to brake pad wear, then the stops 31 limit the movement of the clamping ring (and so on). moving the ring 23 to the left, the ring 30 slides over it without moving. After braking, the pressure ring 23 with the piston
    20 and the clamping ring 30 are moved to the right until the latter stops against the cylinder //. From this moment, the clamping ring 30, being in frictional engagement with the pressure ring 23, holds it moving relative to the cylinder ill, and the piston 20 is pressed back by the spring 28 to its original position and releases the adjusting ring 2-5, which under the action of the springs 27 turns and again
    Adjusts the saw-tooth protrusions to the adjusting ring 24. Thus, 1Ko. is compensated for the increase in the stroke of the annular piston 20 as a result of the wear of the brake pads.
    Spring 29 does not allow when the brake is released, the springs 27 are pressed through the adjusting ring 25 push ring 23 to the brake ring.
    | When installing new pads, the pressure ring 23 should be moved as far as possible in the direction of the annular piston 20, for which it is necessary to exclude the clamping action of the ring 30 first. (This release is made.h stops
    31 and then turning the clamping
    rings 30 until the protrusions 5 coincide with the slots 34.: The annular grooves 32 and 33 are located in the same place of the pressure ring 23 where the ring 30 is located on the new and worn pads, respectively. These grooves facilitate the above-described rotation of the clamping ring 30. Then a special tool is manually inserted into the groove 37 of the adjusting ring 35 and after removing the clamping device 26, the ring 25 rotates against the force of the springs 27, and locks in that position again. Thereafter, the clamping ring 30 is set to the operating position corresponding to the new brake pads.
