The invention relates to a disc brake for a vehicle, particularly for a utility vehicle, comprising: - a brake caliper (1) which is designed to span across a brake disc (2) and in which an application device (8) is arranged; - a single-piece rotary lever (9) which comprises an eccentric element (16); and - at least one brake plunger (6) which is designed as a power screw arrangement (4) having a rotational axis (D) and with which, when said rotary lever (9) is actuated, at least one brake pad (3) can be pressed against the brake disc (2), - said rotary lever (9) being arranged in the brake caliper (1) such that it can pivot relative thereto, and being supported directly or by means of one or more elements connected therebetween, on said brake caliper (1), in at least one support region. The invention is designed such that - the rotary lever (9), which can pivot relative to the brake plunger (6), comprises at least one convexly-formed section (21) on the side thereof that lies opposite the support point on the brake caliper (1), and this section lies against a matching concave end face (23) in the axial extension of the rotational axis (D) of said power screw arrangement (4).

The invention relates to a disk brake for a vehicle, in particular for a utility vehicle, comprising a) a brake caliper (1), which extends over a brake disk (2), b) a brake application device (8) arranged in the brake caliper (1) for pressing brake linings (3) against the brake disk (2), c) at least one brake piston (4), which can be moved axially by means of the brake application device (8), d) an adjustment device (5), which is positioned in the brake caliper (1) and which is operatively connected, by means of a gearing (24), to the brake piston (4) in order to axially adjust the brake piston in order to compensate a clearance change resulting from wear, e) wherein the gearing (24) has an input gear (25), which is retained on the adjustment device (5) for conjoint rotation, and an output gear (26), which is retained on the brake piston (4) for conjoint rotation. The disk brake is designed in such a way that the output gear (26) connected to the brake piston (4) for conjoint rotation and the input gear (25) of the adjustment device (5), which input gear corresponds thereto, are arranged in a driver device (27), which is held in an axially movable but rotationally fixed manner.

The invention relates to an adjuster unit (100) for a vehicle disc brake (1), in particular an air disc brake (1) of a commercial vehicle, comprising an adjustment spindle (101) adapted to be operatively coupled with one of the brake pads (9) such that by rotation in a first direction, the adjustment spindle (101) moves the brake pad (9) towards the disc (11), and by rotation in a second direction opposite of the first direction, the adjustment spindle (101) moves the brake pad away from the disc (11); an actuator ring assembly (107) that is rotatable about the adjustment spindle (101); and a wrap spring (109) that is helically wound around the adjustment spindle (101). In particular, it is suggested that the wrap spring (109), being part of the adjuster unit, is positioned on the adjuster unit, in particular on the adjustment spindle, to engage a stop (117) upon rotation of the adjustment spindle (101) in the second direction, causing the diameter of the wrap spring (109) to increase.
摘要:
Die Erfindung betrifft eine Bremse bzw. Bremszange, die an den Enden ihrer zwei Zangenarme jeweils Bremsbacken aufweist. An dem Ende der Zangenarme gegenüber den Bremsbacken ist zwischen den Zangenarmen eine Krafterzeugungseinrichtung angeordnet und zwischen den Enden der Zangenarme eine Verbindung, z.B. etwa mittig, um die die Zangenarme schwenkbar sind. Die Krafterzeugungseinrichtung weist in einem Gehäuse zwei Spindeln (1, 2) auf, entlang einer gemeinsamen linearen Achse verschieblich an einer Spindelführung geführt sind. Die Spindeln bilden mit ihren Spindelmuttern (15, 16) einen Verschleißnachsteller für Verschleiß an den Bremsbelägen und der Bremsscheibe, wobei die Spindeln (1, 2) und Spindelmuttern (15, 16) bevorzugt symmetrisch zueinander bzw. zu einem Bremszylinderkolben (17) angeordnet sind, der die Spindelmuttern voneinander weg belastet.
