    摘要: A drive arrangement for a motor vehicle, having an internal combustion engine with a crankshaft which can be connected, via an interposed clutch, to a gearbox input shaft of a change-speed gearbox, and having an electric machine—for example an electric motor or a starter-generator—which is provided in the drive arrangement and which has a stator and a rotor. The electric machine, in order to step down its rotational speed, is operatively connected to the crankshaft and/or the gearbox input shaft via a step-down gear mechanism. The step-down gear mechanism is designed as an epicyclic gear mechanism, which has a sun gear, an internal gear and a number of planet gears. The epicyclic gear mechanism can be switched or clutch-operated via two clutches.

    摘要: A parking lock for a vehicle having an electrical drive train including an electric machine with a rotor, a stator having a plurality of stator windings, and power electronics for controlling the electric machine, and a transmission prevents the vehicle from rolling away inadvertently. The parking lock has a mechanical component which is mechanically operatively connected to the rotor when the parking lock is operated to stop rotation of this rotor. The mechanical component has a ratchet wheel and a toothed catch. Furthermore, the parking lock has an electrical component designed such that it produces a short-circuit in the stator windings, at least temporarily, when it is intended to operate the parking lock. When the parking lock is operated, the electrical component is thus activated in a specific time interval before operation of the mechanical component. The short-circuit in the stator windings produces a severe braking torque, which brakes the rotor. The time interval between activation of the electrical component and the activation of the mechanical component allows the rotor to be braked before the mechanical component is activated. In this way, the high torque peaks which occur when the rotor is being stopped are reduced by the electrical component, so that a mechanical component of relatively small size may be used.
