A belt pulley decoupler is provided which is to be arranged on a crankshaft of an internal combustion engine and has a hub provided for coupling to the crankshaft, and a connecting flange of which a distal face is in abutment with the hub in order to transmit torque from the hub to a belt pulley. The connecting flange having a geometry to facilitate a form fit for torque transmission both on the distal face and also on a proximal face which is intended to come into contact with a torsional vibration damper.

Belt pulley decoupler with axial toothing on both sides and auxiliary unit drive

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.
