Friction clutch adjuster, acting via axial bearing - has disc spring, tensioned between clutch plates, and clutch side axial bearing disc, with constant force adjusting range

摘要

A differential friction clutch has a clutch plate adjusting device (18), consisting of two rings (20,21), rotation of one ring (21) w.r.t. the other (20) causing it to move axially, acting via an axial bearing (25) on the clutch plates (29). A disc spring (50) is tensioned between the clutch plates and a clutch-side disc (26) of the axial bearing. The disc spring characteristic curve has a decreasing gradient, with the clutch plate adjusting range occurring in a second essentially constant force range. ADVANTAGE - The spring ensures both effective clutch disengagement and easy clutch adjustment.
