Abstract
A vibration damping apparatus which is installed in the power train between the engine and the variable-speed transmission of a motor vehicle has two coaxial flywheels which are rotatable relative to each other against the opposition of one or more elastic dampers and a slip clutch. The slip clutch is connected in series with the damper or dampers by an axially stressed diaphragm spring.
