Abstract: The crankshaft of a piston engine is assembled with a vibration damper into a discrete module prior to mounting of such module in axial and/or radial bearings of the housing of the engine. The damper has an input element which rotates with the camshaft and a mass which is angularly movable relative to the input element against the resistance of coil springs. The input element can be provided with a sleeve which surrounds a snout at one axial end of the crankshaft. Alternatively, the damper can be installed in or on or can constitute a cheek of the crankshaft. The coil springs can operate in parallel with a friction generating device which also opposes rotation of the input element and the mass of the damper relative to each other.

Abstract: A clutch disc wherein two annular washer-like friction linings flank a two-part resilient cushion which moves the friction linings apart during disengagement of a friction clutch wherein the clutch disc is installed between an engine-driven flywheel and an axially movable pressure plate, and which stores energy during engagement of the clutch. A blocking or movement limiting device, which defines a fulcrum for the friction linings, is provided between the parts of the cushion and/or on the friction linings to prevent an axial movement of the friction linings toward each other beyond a selected minimum distance and to thus compensate for deformation of the flywheel and/or pressure plate as a result of heating attributable to slippage of the pressure plate and flywheel relative to the adjacent friction linings during engagement and disengagement of the clutch.
