Abstract
A belt pulley decoupler includes a belt pulley, a hub to be fixed on the shaft, and a series connection made up of a decoupler spring and a wrap-around band arranged in the drive torque flow between the belt pulley and the hub. The wrap-around band extends about direction of the axis of rotation of the belt pulley decoupler and is arranged radially between the belt pulley and the decoupler spring. Under transmission of the drive torque, both ends of the wrap-around band widen radially, with one end of the wrap-around band being braced against the inner surface of a first sleeve that is rotationally fixed in the belt pulley, and another end being braced against the inner surface of a second sleeve that is rotatable within the belt pulley.
