Clutch cover assembly having a diaphragm spring and a secondary biasing spring working in tandem

摘要

A clutch cover assembly (1) has release load characteristics which have been smoothed out or flattened by using a secondary conical spring (8) in combination with a diaphragm spring (7). To reduce the overall number of parts in the assembly 1, the pressure plate (6) includes axially extending pins (10) which extend through holes formed in the diaphragm spring (7). The pins (10) are also engaged with a portion of the conical spring (8).
