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

Drive wheel of an auxiliary unit belt drive of an internal combustion engine

The decoupler for a drive wheel arrangement for an auxiliary unit of an internal combustion engine has a belt pulley connected to a flexible drive element and a shaft. A damping device is arranged between the shaft and the belt pulley and includes a spring. The belt pulley is connected to a damper cage, which is connected via at least one spring to a damper cage which is positioned such that it can rotate on the shaft.

Decoupler arrangement

A torsional vibration damping apparatus, especially a web damper for mounting on a crankshaft of a piston engine, particularly an internal combustion engine for suppression of natural torsion frequencies from crankshafts can now be economically produced. The apparatus comprises a housing fastened to the engine crankshaft to which at least one rotary mass is coupled with spring elements disposed between the housing and the rotary mass allowing the apparatus to be pre-assembled. Advantageously, multiple parts of the torsional vibration damping apparatus, such as the housing can now be fabricated from more economic sheet metal in place of more costly cast parts.
