Drive wheel for driving unit e.g. generator of internal combustion engine of motor car, has torsional vibration damping device connected with sealing and positioning device, which positions driving disk in axial direction

摘要

The wheel (1) has a traction unit attachment region (5) comprising a driving disk (3). A shaft attachment region (8) and the traction unit attachment region are rotatable relative to each other against a damping effect of a torsional vibration damping device (10). The damping device is connected with a sealing and positioning device, which positions the disk in an axial direction. The sealing and positioning device comprises a sealing element (11) that is pre-stressed between a wall body (18) of the shaft attachment region and a radial inner projection (19) of the disk in the axial direction.
