An application mechanism for a disc brake, particularly a sliding-caliper disc brake. The mechanism comprises an application shaft oriented parallel to the plane of the brake rotor, which shaft is supported, on its side directed toward the rotor (2), against a thrust piece (9) which is movable against the rotor (2). The shaft is supported on its side directed away from the rotor against a support element (14) with respect to which the thrust piece (9) is movable. The support means on the side directed toward the brake rotor are such that the application shaft (8) is de-coupled from the thrust piece (9) with respect to rotation around a first axis (P2) oriented parallel to the longitudinal axis of the shaft (8), but the shaft is coupled with the thrust piece (9) with respect to translational movement of the first axis (P2) toward and away from the brake rotor plane. Further, the support means of the application shaft on the side directed away form the brake rotor are such that the application shaft (8) is coupled to the support element with respect to rotation of the application shaft around a second axis (P1) oriented parallel to the longitudinal axis of the application shaft, which second axis is different from the first axis (P2). The support element is such that the application shaft (8) is de-coupled from the support element (14) with respect to movement of the second axis (P1) parallel to the brake rotor plane, and the thrust piece (9) is mounted for movement, only perpendicularly to the brake rotor plane.

Mechanism for disc brake

A brake application mechanism for a disc brake, particularly a sliding-caliper disc brake having an application shaft which extends parallel to the plane of the brake disc, wherein on the side of the shaft (8) which faces the brake disc (2) the shaft is supported against a thrust piece (9) which is movable against the brake disc (2), support being via a circularly arcuate first contour (17) which is rotatably mounted in a suitable bearing seat (18), and on the side of the shaft which faces away from the brake disc, the shaft is supported against an element with respect to which the thrust piece (9) is movable, support being via a second contour (21) which is eccentric with respect to the first contour. The second contour has at least two circular arcs (I, II) with their centers (P1, P2) and radii (R1, R2) chosen so that when the application shaft is rotated the magnitude of any movement of the thrust piece (9) relative to the application shaft (8) in a direction parallel to the plane of the brake disc is minimized.
