Abstract:
1. A dry double clutch comprising a damper flywheel coupled to an engine and a set double clutch coupled to the damper flywheel to transmit power of the engine to a transmission, wherein the damper flywheel comprises: a connector which is coupled to a drive plate of the damper flywheel so as to be spline-coupled to a connection plate of the set double clutch; a cover which is resiliently coupled rotatably relative to the connector along a circumferential direction thereof to compensate for backlash between the connection plate and the connector; and a first resilient member which is mounted on the connector to resiliently press the cover in the circumferential direction of the connector, and wherein a first clutch disc of the set double clutch has an assembly structure comprised of: a stopper ring which is supported on inner surfaces of the first clutch disc and a first hub toward the transmission to enclose a boundary portion between the first clutch disc and the first hub; a retainer ring which is supported on outer surfaces of the first clutch disc and the first hub toward the engine to be coupled to the stopper ring facing the retainer ring with the first clutch disc being interposed therebetween, thereby enclosing the boundary portion; and a resilient washer which is interposed between the inner surfaces of the first hub and a first drive plate and the stopper ring to resiliently support the first hub.
