F16D 13/75
PCT/DE2014/200147SCHAEFFLER TECHNOLOGIES GMBH & CO. KGAHNERT, Gerd
A ramp body for a ramp system (42) of an adjusting device (29) is provided for adjusting a wear-induced faulty spacing of a pressure plate (9, 10) from a counter-plate (8) of a friction clutch (2, 3), having a base (98) which runs substantially in the circumferential direction, and a ramp (54) which protrudes from the base, wherein the ramp has a ramp surface (100) for sliding on a counter-ramp (50), wherein the ramp surface has an irregular course in the circumferential direction, which irregular course differs from a linear course with a constant gradient. As a result of the irregular course of the gradient of the ramp surface in the circumferential direction, the gear ratio of the ramp system of the adjusting device can be adapted by way of a ramp body of this type to force ratios which change over the wear region, as a result of which it becomes possible to maintain an adjusting function of an adjusting device in a great wear region of a friction clutch, without compromising the functionality of the friction clutch.
