    1402923 Full-face disc brakes H KLAUE 30 Oct 1972 [29 Sept 1972] 49966/72 Addition to 1255450 Heading F2E Each pair of non-rotatable but slidable brake shoes in the modified disc brake consists of two semi-circular members, e.g. 206 3 , 206 4 , the flank edges of which are vertical and abutting, and each of which members is provided with an outwardly-projecting shoulder, e.g. 208. The shoulders engage brackets 209, 210, which are removable for replacement of the brake shoes without dismantling the brake operating mechanism. The brake shoes are forced outwards against rotary members 201, 202, by thrust rings 218, 219, which in turn are forced outwards by actuating rings 211, 212, provided at their adjacent face with ramps, e.g. 212, and separated by balls, e.g. 213. The slight relative rotation of rings 211, 212 to operate the brake is effected by a fluid-pressure operated cam 224. In Fig. 7 (not shown) the brake shoes are forced outwards by a central annular hydraulically-operated piston-and-cylinder device. This embodiment is intended to be associated with the steering knuckle of a front wheel. Reference has been directed by the Comptroller to Specification 1,324,659.

    The invention relates to mechanical engineering, in particular to the automotive industry, and can be used in the design and manufacture of disc brakes, mainly for heavy vehicles. The disc brake is the closest to the invention according to the technical essence and the achieved result. It contains a rotating drum open on the outside, holders of friction linings located between its face surfaces, fixed in the circumferential and movable in axial directions, and the holders have external projections interacting with brake arm and with spacer 1. The purpose of the invention is to facilitate the replacement of wear parts and improve the perception of the braking torque. This is achieved by the fact that the protrusions of each of the holders are arranged in pairs next to each other, and each axial plane passing through a pair of protrusions makes an angle with the axial plane passing through the axis of the drive, the separating plane of the holders. In this case, the angles between the axial plane passing through a pair of protrusions and the axial separating plane are equal to 90 °. FIG. 1 shows a hydraulic disc brake; in fig. 2 is a cross section of disc brake. The brake drum consists of two identical halves 1 and 2, which along their inner perimeter are connected by bolts 3 to each other and to the flange of the hub 4. The brake drum has on its outside radial fins for cooling and are located on the other side of the brake drum half, made in the form of brake surfaces. The hub 4 rotates freely on the supports 5-6, mounted on a rotary axle 7. The semi-ring holders of the friction linings 8-11 with the friction linings 12-15 are supported for axial movement on the guide pins 16 and 17, for example of circular or oval cross section. After folding the guide pins 16 and 17 around the bolts 18, the fingers with the brake bracket 19 connected to the trunnion 4 and the holders of the brake pads 8-11 can be removed without disassembling the control drive. The tabs 20 of the lining holders preferably have the same angular displacement from both ends of the lining holders, therefore the lining holders rest on opposite sides in the same plane passing through the middle of both fingers 16 and 17 of the braking arm 19 and positioned vertically, thereby eliminating the need for additional connecting tools between friction lining holders.
    A hydraulic control actuator is located between the friction holders on the CLADOC and separated from them, having an annular cylinder 21 with lugs 22 with semicircular: points along which the actuator moves in axial direction and is fixed by fingers 16 and 17. The actuator has an annular piston 23, which, together with the annular cylinder 22, closes the annular chamber 24.
    The brake fluid required for the operation of the hydraulic drive is supplied to the annular chamber 24 through the hose 25 and the annular nozzle 26 with the hollow screw 27 through the drilled hole 28. The sealing of the annular chamber 24 provides a sealing ring 29 installed in the groove of the annular piston 23 and the sealing ring 30, placed in the groove of the annular cylinder 21.
    Two insulated rings 31 and 32 are held, for example, by circumferentially located screws 33 between the annular ring or annular piston and friction pad holders, as is. shown for an insulated ring 31. The braking force formed by the brake fluid in the annular chamber 24 drives the cylinder and the piston against the opposing force of the reverse spring 34 suspended between the insulating rings.
    Due to the wear of the friction linings, in order to maintain the established gap between the brake surfaces and the linings, adjustment is necessary, which is made automatically and continuously by the adjusting device. The adjustment device has a support between the insulated ring 31 and the annular cylinder 21.
    a plate 35 fixed by screws 33 to the annular piston 23, on which the pins 36 are riveted. These pins slid through the drilled holes 37 provided in the corresponding places of the annular cylinder 21, in which machines there is a groove 38 in which the spacer rings 39 are located. backlash caused by wear of the friction linings, the spacer rings 39 slide down when braking on the pins 36 and retain the holders of the friction linings 8-11 as they depart, while maintaining a constant distance between them and rotating parts.
