ABSTRACT:
An apparatus for reducing the transmission of vibrations from an engine to a transmission line having a divided flywheel with first and second flywheel elements is provided by the in which the two flywheels are connected to the engine and transmission line, and are respectively connected by a spring mounting and at least two frictional clutches positioned between the two flywheels. The second frictional clutch has frictional contact smaller than the maximum torque of the engine and relative movements between the flywheel elements are effectively damped when the forces acting between the flywheel elements in these relative movements are weaker than the maximum engine torque, but stronger than a predetermined threshold value.
