Abstract
A torsion damping assembly which is installed between the crankshaft of the engine and the input element of the change-speed transmission in a motor vehicle has two coaxial flywheels one of which is driven by the crankshaft and the other of which can transmit torque to the transmission in response to engagement of a friction clutch. The transmission of torque between the two flywheels takes place by way of a damper and a slip clutch which latter is effective only within a selected range of possible angular movements of the two flywheels relative to each other.
Claims6
An assembly for compensation of fluctuations of angular movements, comprising at least two flywheels rotatable relative to each other about a common axis, one of said flywheels being connectable with a combustion engine and another of said flywheels being connectable with an input element of a transmission;
- damper means for opposing rotation of said flywheels relative to each other, said damper means including energy storing means acting at least in a circumferential direction;
- and friction generating means disposed in a torque transmitting path between said flywheels and including at least two friction elements and at least one energy storing device arranged to bias said friction elements in the direction of said axis, said friction elements having ramps arranged to change the bias of said at least one energy storing device in response to rotation of said flywheels relative to each other.
