Abstract
Apparatus for transmitting torque from the output shaft of the engine to the input shaft of the variable-speed transmission in a motor vehicle has a primary flywheel which is connectable to the output shaft, a secondary flywheel which is connectable to the input shaft by engaging a friction clutch, and one or more dampers which oppose rotation of the flywheels relative to each other. The flywheels define an annular chamber for the damper or dampers, and such chamber surrounds two closely adjacent portions of the flywheels which define a radially extending clearance for the flow of cooling air. The radially inner portion of the chamber is separated from the clearance by an annular seal which is located at most midway between the radially innermost and radially outermost portions of an annular friction surface on the secondary flywheel. Such friction surface is adjacent one friction lining of a clutch plate forming part of the friction clutch and being connectable to the input shaft of the transmission. An antifriction bearing is installed between the flywheels radially inwardly of the clearance.
