Abstract

An adjusting device for disk brakes for compensating a play caused by wear comprises a support (6) received in a brake caliper (2) for displacenent transversely of the brake disk (1), an adjusting spindle (7, 8) being arranged for rotation and axial displacement in the support (6), said adjusting spindle comprising, on one end, a brake lining carrier (9) equipped with a brake lining (10), and said adjusting spindle being connected rotationally fast and axially displaceable to a shaft (17) which is engaged by a lever (15) via a clamping roller overrunning clutch (21) for transmission of an adjusting moment whereby an axially pre-tensioned coiled compression spring (22) is arranged crosswise to the turning direction of the lever (15) and is supported at one end on the lever (15) and at a second end on a stationary element (23).

Claims

1. An adjusting device for disk brakes for compensating a play caused by wear, said adjusting device comprising a support (6) received for displacement transversely of a brake disk (1), an adjusting spindle (7, 8) being arranged for rotation and axial displacement in the support (6), said adjusting spindle comprising, on one end, a brake lining carrier (9) equipped with a brake lining (10), and said adjusting spindle being connected rotationally fast and axially displaceable to a shaft (17) which is engaged by a lever (15) via a clamping roller overrunning clutch (21), for transmission of an adjusting moment, characterized in that an axially pre-tensioned coiled compression spring (22) is arranged crosswise to a turning direction of the lever (15) and is supported at one end on the lever (15) and at a second end on a stationary element (23).

2. An adjusting device of claim 1 wherein a conical coiled compression spring (22) is arranged coaxially to the shaft (17) and is supported at one end on the stationary element (23) and at the second end on the lever (15).

3. An adjusting device of claim 2 wherein a larger diameter end of the conical coiled compression spring (22) is supported on the stationary element (23).

4. An adjusting device of claim 2 wherein the stationary element (23) comprises a friction surface (24) for the end of the conical coiled compression spring (22) in contact therewith.

5. An adjusting device of claim 1 wherein the coiled compression spring (22) is connected rotationally fast to the lever (15) or to the stationary element (23).
