| 摘要 |
The invention concerns a parking brake for motor vehicles, vehicle trailers or similar objects with a releasable silent ratchet (41) for conveying the displacement force of the hand brake lever (40) to at least one control cable (1) which leads to a wheel brake, where the silent ratchet (41) exhibits a slide (3), a longitudinally movable toothed (6) clamping element (7), and a pulling element (2) with opposing teeth (8). An adjusting device (42) which operates with spring force and inclined planes (12, 13) effects the engagement of the teeth (6, 8) when the hand brake lever (40) is pulled. At least on one side, the pull rod (2) exhibits teeth which operate together with a clamping element (7) and on the opposing side (9) an even wall, with which it is guided along the facing inner surface (10) of the slide (3). The clamping element (7) is guided along the slide (3) and capable of longitudinal and lateral movement, whereas the silent ratchet (41) exhibits a release device (43) which separates the clamping element (7) from the pulling element (2). |
