ABSTRACT:
A device to be connected between the engine and power train of a construction vehicle or the like for damping the fluctuations of the engine output torque. The damper comprises a drive plate and a retaining plate coaxially connected to each other for simultaneous rotation, and a driven plate coaxially mounted between the drive and retaining plates for angular displacement within limits. Mounted between the retaining plate and the driven plate are a friction plate and a disc spring, with the friction plate being biased by the disc spring into frictional contact with the driven plate. The friction plate has a conical contact surface which, under the bias of the disc spring, makes frictional contact with the driven plate under even pressure. Two other friction plates lie between the drive and driven plates and make frictional contact with the driven plate and with an intermediate plate in positive engagement with the driven plate. A plurality of springs act between the drive and retaining plates and the driven plate for absorbing torque fluctuations when a slip occurs therebetween.
