Abstract

A belt pulley arrangement with a belt pulley that is fastenable to rotate on a shaft, a torsion spring arranged within the belt pulley for enabling a transmission of torque between the belt pulley and shaft. The torsion spring acts with one end against the shaft and with an other end against the belt pulley. A looped flat spiral spring is arranged radially between the belt pulley and the torsion spring and acting as a free-running clutch. The torsion spring is arranged on one of its axial ends in a first sleeve that is connected so that it can rotate with a radial inner lateral surface of the belt pulley. The looped flat spiral spring is arranged radially between the first sleeve and the torsion spring, and contacts, in its extended state, at least in some sections on the inner lateral surfaces of the first sleeve and belt pulley.
