ABSTRACT:
A flywheel assembly has a first flywheel which is connectable to the output shaft of an internal combustion engine, and a coaxial second flywheel which is connectable with the input shaft of a variable-speed transmission in response to engagement of a friction clutch. The flywheels are rotatable relative to each other by deforming the coil springs of a first damper which substantially unassistedly offers a relatively small resistance to such rotation during an initial stage of angular movement of at least one flywheel in at least one direction from a neutral position relative to the other flywheel, and thereupon by deforming the coil springs of at least one second damper which offers a greater resistance to a further stage of angular movement of the at least one flywheel from the neutral position. The dampers compensate for fluctuations of torque which is transmitted between the engine and the transmission.
