DRIVE SYSTEM FOR A VEHICLE |
摘要 |
A drive system for a vehicle comprises an internal combustion engine switchable between operating modes of different performance capability, and a torsional vibration damping arrangement that comprises a primary side preferably coupled to a crankshaft and a secondary side rotatable with respect to the primary side against the action of a damper element arrangement. The damper element arrangement has a stiffness which increases as the load torque to be transmitted increases, and the primary side and the secondary side are in a limiting relative rotational position with respect to one another during transmission of a maximum torque which can be delivered in an operating mode with lower performance capability at a maximum torque rotational speed, and the damper element arrangement provides a limiting stiffness in the limiting relative rotational position such that a natural frequency of the torsional vibration damping arrangement is below the maximum torque speed. |
