Abstract
The invention relates to a drive assembly comprising a constant velocity fixed joint 1 with an outer part 4 provided with a flange 7, and a damping element 3 in the form of a ring. The damping element 3 is arranged between the flange 7 and, respectively, the flange-like portion of a cover 19 closing the outer part 4 and the attaching part 20. The damping element 3 includes an aluminum material whose modulus of elasticity greatly deviates from that of the outer part 4, so that any structure-borne sound vibrations originating from the drive end, for example from a drive unit of a motor vehicle, cannot be transmitted from the attaching part 20 into the driveline which includes the constant velocity fixed joint 1. In this way, vehicle comfort is improved.
