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.

Brake application mechanism for a disc brake

An operating mechanism (17) for a sliding caliper disc brake including a caliper housing (1) a thrust element (9) slidably mounted in the housing for reciprocating movement toward and away from a disc brake (2), two thrust spindles (10, 11) in screw threaded engagement in the thrust element (9) each having on their ends caliper feet (12, 13) engaging against a brakehead on which brake linings (3) are mounted, a brake shaft (8) rotatably mounted in the housing (1) so that rotation of the brake shaft about an axis of rotation (B) in an actuating direction moves the thrust element (9) toward the brake disc and rotation in the opposite direction retracts the thrust element, a force-dependent freewheeling clutch drive (18) coupled on one side to the brake shaft (8) and on the other side to the thrust spindles (10, 11), a recess (16) in the brake shaft (8), and an operating mechanism (17) for coupling the clutch drive (18) to the thrust spindles (10, 11) having an operating shaft (25) extending through the recess (16) and through the driven operating ring (21) of the clutch drive, the operating ring having an internal profile interengaging with an external profile on shaft (25) with limited relative rotational movement therebetween provided by gap (S) which determines the brake clearance in the non-actuated position. Bevel gears (26, 27) on operating shaft (25) engaging with double gears (29, 30) on actuating shafts (31, 32) for operating the thrust spindles (10, 11) during use for maintaining proper brake clearance.
