Abstract
A belt pulley arrangement for a belt drive for driving auxiliary units of a motor vehicle, comprising a belt pulley for introducing a torque that can be supplied by a traction mechanism, an output shaft for driving an auxiliary unit, particularly a coolant pump, an electric machine for transmitting torque between the belt pulley and the output shaft, the electric machine including a rotor connected to the belt pulley and a stator connected to the output shaft, and being able to be electrically connected to an electric energy source for the purpose of accelerating the output shaft and/or to an electric energy sink in order to decelerate the output shaft, a first rotational speed measurement device for detecting the time curve of the rotational speed of the belt pulley and/or a second rotational speed measurement device for detecting the time curve of the rotational speed of the output shaft, and a control device connected to the electric energy source and/or electric energy sink so as to control an output shaft rotational speed time curve by temporarily electrically connecting the energy source and/or energy sink in reaction to the rotational speed time curve that has been detected.…
