ABSTRACT:
A two-stage clutch damper assembly for use in an automotive vehicle adapted to dissipate the irregular impulses of a vehicle diesel engine when the transmission is in neutral, the clutch is engaged and the engine is at idle rpm. The assembly includes a clutch plate, a spring retainer plate secured to the clutch plate, and a main hub in operative engagement with the transmission input shaft and having an integral hub flange with spring notches opened to allow an additional rotational travel of the clutch and spring retainer plates relative to the hub. An intermediate hub has a radial flange between the clutch plate and main hub and an inner hub is concentric in said intermediate hub and spring-biased away from said main hub. The inner hub is splined onto the transmission input shaft, and the inner and intermediate hubs have interengaging helical teeth so that rotary motion of said intermediate hub results in axial movement of said inner hub.
