ABSTRACT:
A composite torsional vibration damper which can be utilized with advantage in the clutch disc of a friction clutch in the power train of a motor vehicle has a composite input member which can be driven by the output element of a combustion engine, an output member which is angularly movable with and relative to the input member about a common axis and can transmit torque to the input element of a variable-speed transmission, and first and second dampers which operate in series to oppose different angular movements of the input and output members relative to each other. The first damper is disposed radially inwardly of the second damper and its rigidity is less than that of the second damper. The energy storing elements of the first damper permit an angular movement of the input and output members relative to each other through an angle of at least 20.degree., and the second damper permits such angular movement through an angle of at least 15.degree.. The first damper can transmit a maximum torque of between about 4 N-m and 20 N-m, and the second damper has a torsional spring rate in the range of between about 5 and 40 N-m/.degree..
