A torque-transmission system with a decoupler (1) between a shaft (2) and a belt pulley (3) of a starter generator is provided. The belt pulley can rotate relative to the shaft (2). For reducing rotary oscillations, the decoupler (1) includes a damping device arranged between the belt pulley (3) and the shaft (2) with at least one spring element (5). The decoupler (1) includes an automatic locking device (7) that is dependent on a direction of rotation and that produces, at a low rotational speed level, a coupling between the belt pulley (3) and the shaft (2), and this coupling automatically disconnects when a pre-determined rotational speed is reached.
A decoupler for a torque-transmission system between a shaft and a belt pulley of a starter generator in which belt pulley can rotate relative to the shaft, the decoupler comprising at least one spring element for reducing rotary oscillations as a damping device between the belt pulley and the shaft, and a rotational direction-dependent, automatic locking device that creates a coupling between the belt pulley and the shaft at a low rotational speed level, and automatically disconnects the coupling when a predetermined rotational speed is reached.
