Ramp device for a friction clutch adjusting device, specially for automotive vehicles

摘要

The clearance take-up mechanism consists of a series ofinclined surfaces (15) spaced circumferentially and designed to co-operate with the clutch pressure plate. It also has thrust members to receive the axial effort of the diaphragm, and teeth (18) to drive it, meshing with an endless screw. The inclined surfaces are situated on one face, alternating with thrust zones (14). The teeth project at right angles to the ring's axis and are located on the outer edge of one of the thrust zones. Alternatively, the teeth can be situated on an extended and folded portion of the ring's rim.
