DIAPHRAGM SPRING CLUTCHES

摘要

In a diaphragm spring clutch cover assembly one of the annular fulcra for the diaphragm spring is cushioned in order to supplement or replace the cushioning normally incorporated between the friction facings of the driven plate. The cushioning in the fulcrum includes a wavy ring some of whose undulations are of greater height than the others to give a progressive engagement of the clutch.
