| 摘要 |
The invention relates to an adjusting device (1) for compensating for the wear of a brake lining or multiple brake linings and/or a brake disc of a pneumatically actuatable disc brake for a vehicle. The adjusting device (1) has a mechanical actuator (3), and the mechanical actuator (3) converts a rotational movement of a brake lever (5) into a rotational movement of a shaft (10). The shaft (10) rotates at least one threaded spindle (19) which acts on one of the brake linings. The invention is characterized in that the adjusting device (1) can carry out an advancing movement and a return movement of the threaded spindle (19), and the advancing movement and the return movement of the threaded spindle (26) can be terminated by switching one or more couplings (29, 30, 32). |
