Abstract
A parking lock device for a vehicle includes a main actuator of an electromagnetic type and a blocking actuator of an electromagnetic type. The blocking actuator includes a blocking plunger configured on the one hand to cooperate, in at least one blocking position, with the main plunger and on the other hand to disengage from the main plunger in an unlocked position. An anti-rotation device is configured to prevent rotation of the main plunger on itself.
Claims20
A parking lock device for a vehicle, in particular for a motor vehicle driven by an electric motor, this parking lock device being able to cooperate with a parking lock wheel which is connected for conjoint rotation to a shaft of a drive train and which has an alternation of teeth and recesses, and this parking lock device comprising:
- a main actuator of an electromagnetic type, comprising a main plunger configured to be moved in a magnetic field generated by a coil of the main actuator, the main plunger being configured to be moved, along an axis of movement of this main plunger, between an open position, in which the main plunger leaves the wheel disengaged, and a closed position, in which the main plunger causes the wheel to be blocked,
- a blocking actuator of an electromagnetic type, comprising a blocking plunger configured to be moved in a magnetic field generated by a coil of the blocking actuator, the blocking plunger being configured on the one hand to cooperate, in at least one blocking position, with the main plunger or an optional lever actuated by the main plunger in order to block this main plunger or this optional lever in particular in the closed position, and on the other hand, in an unlocked position, to disengage from the main plunger or from this optional lever, this optional lever having a second finger configured to be moved into a recess in the wheel in order to block the wheel in the closed position of the main plunger, and, when the main plunger is in the open position, the lever leaves the wheel disengaged,
- an anti-rotation device configured to prevent rotation of the main plunger on itself.
