ABSTRACT:
A multiple stage damper for the driven member of a vehicle clutch which eliminates objectionable vibration during both engine idle and while the vehicle is in motion. The damper comprises inner and outer hubs with springs therebetween and additional damper springs between the outer hub and the clutch and spring retainer plates to provide two or more damping stages. A two stage damper results when the springs connecting the inner and outer hubs work simultaneously, while a three stage damper results when a first spring or springs are actuated prior to a second spring or springs providing a sequential damping action.
