Wear compensation for car clutch - uses ratchet effect on declutching pedal with cable tensioning spring returning pedal towards clearance stop

摘要

The wear-compensating device is used on an automobile clutch which is operated by a declutching pedal (10) with a fixed fulcrum (13). It may function by taking up the slack in a clutch-actuating cable (C) whilst maintaining its tension. A tensioned coil spring (18) maintains the cable tension and also returns the pedal onto a clearance stop (21). A second lever (14) is mounted on the pedal fulcrum, its free end locating e.g. a rotatable gear segment (15) to which the cable is anchored. Relative rotation of the gear segment and the pedal is prevented by providing complementary teeth (11) on the latter. The segment and the pedal separate when the pedal meets the stop and the spring extends between the segment and a pedal lug (20). The cable may traverse a cam-shaped head (30) of the pedal.
