ABSTRACT:
A torque transmitting mechanism has an elastomeric drive mechanism in series with a friction drive mechanism. The elastomeric drive mechanism permits angular excursion between the frictional drive input and the drive mechanism output. To provide this relative motion, an elastomeric belt circumscribes a plurality of cam members which are formed on respective gear members. The gear members are rotatably mounted on the friction drive mechanism and mesh with a gear spline formed in the output member of the drive mechanism. When the torque transmission level is increased, the gears rotate so that the cam members also rotate resulting in an increase in the length of the elastomeric belt thereby increasing the tension therein while permitting the angular excursion between the input and output and simultaneously damping transient torsional vibration.
