Abstract

A torsion damping assembly for the clutch plate of a friction clutch has an input component with two discs one of which carries the friction linings and which are rotatable within limits relative to a hub which transmits torque to a transmission and has external teeth in loose mesh with the internal teeth of the flange of a main torsion damping stage. The flange is disposed between the two discs and has windows for strong coil springs which further extend into registering windows of the discs. A further damping stage has two spaced-apart plates which are affixed to the flange in the space between such flange and one of the discs and are disposed at the opposite sides of a second flange which is non-rotatably secured to the hub. The second flange has windows for relatively weak coil springs which further extend into registering windows of the two plates.
