Device for tensioning power transmission belt in continuous variable traction drive with variator for driving auxiliary units of motor vehicle, has roller entwined by power transmission belt, where roller is formed as belt pulley

摘要

The device has a roller (2,13) entwined by a power transmission belt (1,15), where the roller is formed as a belt pulley (2,13) and another roller (3,12) entwined by the power transmission belt, where the latter roller is formed as another belt pulley. A variator is arranged on a mounting plate (8). The variator has a tension roller (6,14). An independent claim is included for a method for tensioning a belt drive.
