Belt drive for combustion engine in motor car, has belts partly looping in partial region, where one of belts is partially embraced through driven pulley and technically connected with another auxiliary unit

摘要

The drive (10a) has a driving pulley (11a) and a driven pulley (12a) connected to an auxiliary unit. Belts (13a, 14a) are arranged in a common belt plane. One of belts partly loops the driving pulley and the driven pulley for driving the auxiliary unit. The belts are partly loops in a partial region (15a), and one of belts is partially embraced through the driven pulley and technically connected with another auxiliary unit. An inner side of one belt comprises pointing grooves that engage with a corresponding profile of the pulleys in a travel direction.
