Abstract
A torque transmitting mechanism which operates between the crankshaft of the engine and the input shaft of the change-speed transmission in a motor vehicle has a first flywheel which is driven by the crankshaft, a second flywheel which can drive the input shaft through the medium of a friction clutch, and three series-connected dampers between the two flywheels. At least one of the dampers is a slip clutch, and the torque which can be transmitted by such slip clutch is variable. The dampers are designed to compensate for all fluctuations of torque which is transmitted between the crankshaft to the input shaft. The first damper can constitute a slip clutch the input element of which receives torque from the crankshaft, the second damper can constitute a slip clutch the input element of which is the output element of the first damper and the output element of which is the input element of an elastic damper operating between the second slip clutch and the second flywheel.
