Abstract
A belt pulley decoupler for transmitting drive torque from the belt of an auxiliary unit belt drive to the shaft of one of the auxiliary units is provided, including: a belt pulley, a hub to be mounted on the shaft, a first sleeve, which is rotationally fixed in the pulley, a second sleeve, which is rotatable in the pulley, and a series circuit of a decoupler spring and a disposed in the drive torque flow between the belt pulley and the hub. The wrap-around band ends, which couple the two sleeves to one another non-rotatably while transmitting the drive torque, extend the wrap-around band radially. One of the two sleeves has a circumferentially extending slot and the wrap-around band end coupled to this sleeve is configured as a leg, which interlockingly engages in the slot non-rotatably in a direction of rotation of the drive torque.
