The return spring (21) includes a fixed portion (22), which is on a base end side fixed to an ear portion (7B) of a back plate (7) of the friction pad (6). Then, an abutment portion (25), which is on a distal end side of the return spring (21), is elastically brought into abutment on an abutment plate portion (13D) of a pad spring (13), which is on the mounting member (2) side at a position on an outer side in a disc radial direction relative to the fixed portion (22).

A disc brake for heavy vehicles. The disc brake may include first and second brake pads, a caliper, and at least one support. The caliper may have a radial opening and a pad strap. The support may support a rear face of at least one of the brake pads and may have a guide formation that may be configured to engage the pad strap and restrict rotation of the brake pad about a radial axis.

A disc brake whose carrier (11) includes two opposite arms (14F, 14B) each including a C-shaped axial housing (16F, 16B) accommodating a brake pad (12) including two opposite lateral lugs (26F, 26B), each lug (26) accepting a pad spring (40F, 40B) including at least one lower, sliding, branch (42F, 42B) and in which a lamellar element (22F, 22B) is interposed between the lug (26F, 26B) and the C-shaped housing (16F, 16B), this element (22F, 22B) including a lower first sliding flange (24F, 22B) accepting the sliding branch (42F, 22B) of the pad spring (40F, 40B) and an upper second flange (25F, 25B) for bearing vertically in the housing (16), at least one tangential preload spring (60B) for tangentially preloading the pad (12) interposed between an arm (14B) and the pad (12) and constantly urging the pad (12B) in a direction (DF) that is horizontal overall from the back forward.
摘要:
A caliper disc brake of a vehicle, in particular of a commercial vehicle, with a brake disc having an axis of rotation, a brake caliper (20), a brake anchor plate (22), a force transmission element, such as, for example, a lining support (26) and/or a pressure plate, which is guided and supported in a shall of the brake caliper or of the brake anchor plate, a holding-down spring (32) for holding down the force transmission element, and a holding-down device (36) which is held and supported on the caliper by a holding device, pretensions the holding-down spring radially against the force transmission device and pretensions the holding-down spring tangentially in the direction of rotation against the force transmission device during forwards travel, wherein the holding device has a centre line lying parallel to the axis of rotation. The tangential pre-tensioning is at least partially attributed to the fact that the dimension of the holding-down device, as measured in the tangential direction from the centre line, are larger at least in sections on the disc exit side than on the disc entry side.

A brake pad retaining device is provided for holding a brake pad within a brake caliper of an air disc brake system. The device may be formed as a spring which provides at least four retention forces at longitudinal ends of the brake pad in order to suppress brake pad kick motion and vibration, while applying a biasing force that pre-loads a caliper to its mounting pins. The device may include a mounting section that is coupled to a brake carrier, a first projection and a second projection. The first projection extends from one region of the mounting section to a region near a longitudinal end of the brake pad to thereby exert a radially inward force against the brake pad. The second projection extends from another region of the mounting section to an inner surface of the brake caliper to thereby exert a biasing force against the brake caliper.

An urging spring (15) urges a friction pad toward the exit side of the rotational direction of a disk when a vehicle equipped with the disk brake runs forward. The urging spring is disposed between a lug portion (11A) of the friction pad and a torque receiving surface (5) of a carrier (2). The distal end of the urging spring is configured to abut against the disk to perform wear detection. The urging spring includes a mounting portion (15A), a first extending portion (15B), a boundary region (15E), a bent portion (15C), and a second extending portion (15D). The boundary region is reduced in width to lower stiffness. The bent portion is increased in width and provided with reinforcing portions, thereby enhancing the stiffness. Thus, the natural frequencies of the second extending portion in the rotational direction K and the vertical direction J come close to each other.

The invention relates to a cable-actuated disc brake for a bicycle. The cable-actuated disc brake has a lever with dual, opposing piston assemblies that limit the movement of brake pads in relation to a brake disc of the bicycle. The lever includes symmetrical lever arms respectively engaged with symmetrical piston assemblies that are axially spaced, coaxially aligned and rotate about a pivot axis to selectively engage brake pads with a brake disc of the bicycle.
