FRICTION CLUTCH DRIVEN PLATE

摘要

A friction clutch driven plate comprises a hub with a small integral flange and an outer flange portion coupled to the hub through a lost motion connection associated with interengaging teeth. In addition to main torsional damping springing associated with springs in windows in the outer flange portion and side plates of a friction facing carrier, auxiliary circumferentially acting springing acts between the hub and the outer flange portion. The auxiliary springing comprises two springs, one to each side of the hub flange. The springs are circumferentially extending spring arms engaged in the hub and outer flange portion and together are much weaker than the main springs taken together and provide damping to prevent idle rattle while the main springs provide friction damping during transmission of torque through the driven plate.
