Abstract
A belt pulley decoupler for the drive torque transmission between a belt of a starter-generator belt drive and the starter generator is provided. A hub is fastened on a generator shaft of the starter generator. A decoupler spring is configured to transmit drive torque of the belt from the belt pulley to the hub when the starter generator is powered. A rotary stop has a stop part on the belt pulley and a stop part on the hub. The rotary stop is configured to transmit drive torque of the generator shaft from the hub to the belt pulley when the starter generator is driving the belt. The decoupler spring is loaded in both torque directions and participates in the transmission of the drive torque from the hub to the belt pulley when the starter generator is driving the belt.
