Abstract
The invention relates to an assembly drive or traction mechanism drive, which is designed as a belt drive, of an internal combustion engine, with one tensioning roller and/or one deflecting roller which encloses in each case one belt pulley. In the operating state of the belt pulley, a traction mechanism, which is designed as a V-ribbed belt, is guided on the running surface of the belt pulley. Here, the belt pulley of the deflecting roller has a smooth running surface against which the V-ribbed belt is supported with the profiled inner side.
Claims8
