Title: Disc brake friction pad support and biasing assembly.
IPC: F16D65/095
Filed: 1984-08-30
Abstract: The vehicle disc brake comprises a rotor having opposite friction surfaces secured for rotation with a vehicle wheel. A caliper is slidably mounted to a support, the caliper having a leg depending adjacent one friction surface of the rotor. A force transmitting plate is adjacent the other friction surface of the rotor. - A reaction abutment is provided between the actuator and caliper. A friction pad is disposed between the force transmitting plate and rotor. A second friction pad is disposed between the depending caliper leg and rotor. A radial outer portion of the first friction pad is supported on the caliper. The friction pad is biassed axially into contact with the force transmitting plate to prevent vibration of the friction pad. (2/8) EPAB- EP-143170 B A vehicle disc brake comprising a rotor (30) having oppositely disposed friction surfaces (31,32) secured for rotation with a vehicle wheel, a caliper (12) slidably mounted to a support, said caliper (12) having a leg (40) depending adjacent one friction surface (31) of said rotor, actuating means (43) adjacent the other friction surface (32) of said rotor, reaction abutment means between said actuating means (43) and said caliper (12), a first friction pad (34) disposed between said actuating means (43) and said rotor, a second friction pad (37) disposed between said depending caliper leg (40) and said rotor, means supporting a radially outer tab (35) of said first friction pad (34) on said caliper (12), a fastener (91,92) having a shank (98,99) terminating in a head and biasing means (85) for axially biasing said first friction pad (34), characterised in that said fastener is secured to a threaded bore (94,95) in a force transmitting plate (47) interposed between said actuating means (43) and said first friction pad (34), said fastener shank projecting from said bore (94,95) through an aperture in said friction pad (34), said aperture being greater in diameter than said fastener shank, and said biasing (85) acting between said fastener head and said first friction pad (34) to bias said first friction pad (34) toward said force transmitting plate (43) while permitting lateral movement of said first friction pad (34) relative to said force transmitting plate (43).

(9pp) USAB- US4527668 A The disc brake comprises a rotor having oppositely disposed friction surfaces secured for rotation with a vehicle wheel. A caliper is slidably mounted to a support and has a leg depending adjacent one friction surface of the rotor. An actuator includes a force transmitting plate adjacent the other friction surface of the rotor. A friction pad is disposed between the plate and the rotor. - A second friction pad is disposed between the leg and the rotor, A radially outer tab of the friction pad is supported on the caliper, A fastener is secured to a threaded bore in the plate. The fastener has a shank projecting from the bore through an aperture in the radially outer tab of the pad and terminating in a head. A spring lies between the fastener head and the pad biasing the pad towards the plate while permitting lateral movement of the pad relative to the plate.
