Abstract

The invention relates to a drive wheel (1) of an auxiliary unit belt drive of an internal combustion engine, having a running casing (2) which is operatively connected to a traction mechanism, having a hub (3) which is rotationally fixedly connected to the drive axle of an auxiliary unit, and having a damping device (4), which is arranged so as to act between the running casing (2) and the hub (3), for reducing rotary oscillations, with the damping device (4) comprising a spring store (5) which is arranged so as to act between the running casing (2) and the hub (3). In order that the running casing can be produced more economically, the invention provides that the running casing (2) is composed of a running part (6), a driver part (7) and a spring receptacle (8), with the running part (6) being rotationally fixedly and permanently connected to the driver part (7), and wherein the driver part (7) can be or is connected in a form-fitting manner to the spring receptacle (8).
