Damping plate assembly for vehicle clutch - has regulatory device providing stable hysteresis dependent on operating direction.

摘要

A damping plate assembly has an input rotations element, and a hub (1) attached to an output element, which is radial to a flange (2). An elastic element provides a flexible connection of the input rotation elements and the hub flange, and several friction elements are mounted between the input rotation element and the hub flange. A regulatory device provides for the use of only a chosen number of friction linings, and is dependent on whether the damping assembly operates in one phase of the input rotation relative to the flange in a positive direction, or in a phase constituting a negative direction. ADVANTAGE - Stable hysteresis torque characteristic according to positive or negative torsion phase.
