Abstract
Described herein is a pulley assembly for a start-stop belt drive, comprising a hub having an axis and designed to be connected to a crankshaft of an internal-combustion engine, a pulley, which is designed to co-operate with a belt of a belt drive and is connected in a rotatable way on the hub, and a seismic mass, which is connected to the hub so as to rotate with respect to the hub so as to define a damping device for damping torsional vibrations. The pulley assembly comprises a band clutch co-operating selectively between the hub and the pulley and comprising a coil element and electromagnetic actuation means for governing clutching and de-clutching of the coil element.
