ABSTRACT:
Apparatus for transmitting torque in the power train of a motor vehicle has a first flywheel which is connected to the crankshaft of the engine and a second flywheel which is coaxial with and can rotate relative to the first flywheel and is connectable with the input shaft of the variable-speed transmission by a friction clutch. A composite damping device between the flywheels has an outer damper which is first to respond when the flywheels leave their starting angular positions relative to each other, and an inner damper which is in series with the outer damper and has an output element rigid with the second flywheel. The output element of the first damper is a coupling member having two discs which flank the output element of the second damper and one of which is centered by the peripheral surface of an annular part on the output element of the second damper. The outer damper has coil springs which are interposed between the first flywheel and the discs of the coupling member, and the inner damper has coil springs which are interposed between the discs and the output element.
