Abstract

A torque transmitting assembly which can be installed between the engine and the change-speed transmission of a motor vehicle has a first flywheel which is driven by the crankshaft of the engine and a second flywheel which is movable axially of the first flywheel and can drive the transmission through the medium of a friction clutch. A damper is installed between the two flywheels to transmit torque while permitting some angular movement of the flywheel relative to each other. At least one antifriction bearing is installed between the two flywheels with some freedom of axial movement between its races. The races are stressed axially relative to each other in one direction in the engaged condition and in the opposite direction in response to a change in the condition of the clutch. The second flywheel is permanently biased toward or away from the first flywheel, depending upon the type of the clutch, and the disengagement of the clutch results in axial movement of the second flywheel relative to the first flywheel with attendant reduction of friction between the two flywheels in the engaged condition of the clutch.
