Abstract

A torsion damping assembly which is installed between the crankshaft of the engine and the input shaft of the change-speed transmission in a motor vehicle has two coaxial flywheels which are rotatable within the limits relative to each other against the opposition of two series-connected dampers. One of the dampers has an input element in the form of two coaxial discs which are affixed to one of the flywheels and bear against the radially outwardly extending arms of a flange-like torque transmitting output element constituting the input element of the other damper. The output element of the other damper is constituted by two discs which are disposed radially inwardly of the discs of the one damper, which directly or indirectly bear against the adjacent portion of the flange-like output element of the one damper, and which rotate with the other flywheel.
