Abstract
A belt pulley arrangement for a belt drive to drive auxiliary units of a motor vehicle, having a belt pulley for introducing a torque that can be provided via a flexible drive means, an output shaft for driving an auxiliary unit, in particular a cooling water pump, and an electric machine for the transmission of torque between the belt pulley and the output shaft, wherein the electric machine has a rotor connected to the belt pulley and a stator connected to the output shaft. As a result of the power flow between the belt pulley and the output shaft, which can be influenced by the electric machine, it is not necessary to design the auxiliary unit that is attached via the output shaft for the least beneficial operating point, so that the auxiliary unit can be dimensioned smaller and a reduction in the installation space for motor vehicle components, in particular the installation space for auxiliary units of a motor vehicle that can be driven via the belt drive, is made possible.
