ABSTRACT:
An apparatus which can transmit torque between the crankshaft or the camshaft of a combustion engine and the input shaft of a variable-speed transmission in the power train of a motor vehicle employs a damper having a rotary input member normally receiving torque from the engine, an output member rotatable with and relative to the input member and normally transmitting torque to the transmission, and a set of arcuate coil springs which yieldably oppose angular movements of the input and output members relative to each other with a first force which increases in response to increasing angular movements of the input and output members relative to each other and with a second force which is generated by centrifugal force and increases in response to increasing RPM of the engine. At least one additional spring is provided to oppose angular movements of the input and output members relative to each other (particularly when the vehicle is coasting) with a third force which increases in response to increasing angular movement of the input and output members relative to each other but is at least substantially independent of the centrifugal force.
