Abstract
A torque-transmission system with a decoupler () between a shaft () and a belt pulley () of a starter generator is provided. The belt pulley can rotate relative to the shaft (). For reducing rotary oscillations, the decoupler () includes a damping device arranged between the belt pulley () and the shaft () with at least one spring element (). The decoupler () includes an automatic locking device () that is dependent on a direction of rotation and that produces, at a low rotational speed level, a coupling between the belt pulley () and the shaft (), and this coupling automatically disconnects when a pre-determined rotational speed is reached.
