Abstract
A sheave which can be connected to the output shaft of an internal combustion engine in a motor vehicle has a rotary input element, an output element which is coaxial with and rotatable relative to the input element and is provided with a rim for one or more endless belts or chains, one or more bearings between the input element and the output element, a damping unit which opposes rotation of the two elements relative to each other, and an inertial damper which is connected between the output shaft and the input element. The inertial damper has a ring-shaped mass which is at least partially surrounded by and is closely adjacent the rim. The rim, the inertial damper and the damping unit are interfitted in the axial direction of the sheave to contribute to compactness of the sheave.
