ABSTRACT:
A power transmission unit for automotive vehicles includes a change-speed mechanism, a final drive gearing and a differential gear unit assembled within a casing, the change-speed mechanism having an input shaft drivingly connected to an engine by a friction clutch assembly, and the final drive gearing connected to an output shaft of the change-speed mechanism to drive the differential gear unit. The input shaft is in the form of a torsion bar to reduce torsional rigidity of the drive power train, and a friction member is provided to restrain twisting vibration of the input shaft.
