Abstract: In one example, a hybrid drive unit comprises an electric motor, an axle differential for connection with a further motor, a first axle half shaft and a second axle half shaft connected to the axle differential, a first clutching device and a second clutching device. The electric motor is selectively drivingly engagable with the first axle half shaft via the first clutching device and with the second axle half shaft via the second clutching device.

Abstract: Methods and systems are provided for a vehicle park lock. In one example, the park lock may be configured with a first portion having a first set of teeth and a second portion having a second set of teeth configured to engage with the first set of teeth. The first portion may be coupled to a rotating part of the vehicle while the second portion may be coupled to a stationary part of the vehicle. The second portion may include actuating devices to actuate the sliding of the second set of teeth, the actuating devices including a motion source, elastic elements, and one or more ramps.

Abstract: A park-lock device having a gearwheel connected to a rotating member; a tilting lever with a locking tooth engagable with the gearwheel to prevent rotation thereof, the tilting lever is tiltable about a first axis of rotation between a disengagement and engagement position; and a spring that applies torque on the cam. The cam is mounted about a second axis of rotation parallel to the first axis of rotation and has a first lateral surface portion that cooperates with a first cam follower of the tilting lever. The tilting lever has a second cam follower and the cam has a second lateral surface portion that cooperates with the second cam follower. In a first rotational direction the cam causes the tilting lever to tilt from the disengagement to the engagement position. In a second direction the cam causes the tilting lever to tilt from the engagement to the disengagement position.

Abstract: An actuation unit has a primary motor and a transmission mechanism for transmitting motion generated by the primary motor to a control member. The transmission mechanism includes a first transmission member connected to a drive shaft of the primary motor, a second transmission member drivingly connected to the control member, and a coupling member shiftable between an engagement position and a disengagement position. The transmission mechanism further includes a first elastic member interposed between the first transmission member and the second transmission member to cause rotation of the second transmission member relative to the first transmission member when the coupling member is in the disengagement position, a second elastic member for elastically urging the coupling member towards the engagement position, and an auxiliary actuation device for shifting the coupling member from the engagement position to the disengagement position.

Abstract: The friction clutch comprises: a driving part comprising at least one first friction element; a driven part comprising a hub and at least one second friction element drivingly connected for rotation with the hub; at least one spring configured to press the friction elements of the driving part and of the driven part against each other by applying an elastic force on these friction elements; and an actuation unit arranged to bring about opening of the friction clutch by applying directly or indirectly on the at least one spring an actuating force directed in the opposite direction to the elastic force so as to move the friction elements away from each other. The actuation unit comprises a thrust bearing, at least one force transmission member and a hollow actuating member arranged to apply the actuating force on the at least one spring via the thrust bearing and the at least one force transmission member. The hollow actuating member is arranged on the opposite side of the hub to the at least one spring.

Abstract: The park-lock device comprises: a gearwheel intended to be connected for rotation with a rotating member of the transmission; a tilting lever provided with a locking tooth arranged to engage the gearwheel to prevent rotation of the gearwheel, the tilting lever being tiltably mounted about a first axis of rotation (x1) between a disengagement position and an engagement position; and a control unit for controlling the tilting movement of the tilting lever about the first axis of rotation (x1) between the disengagement position and the engagement position. The control unit comprises a cam which is rotatably mounted about a second axis of rotation (x2) parallel to the first axis of rotation (x1) and has a first lateral surface portion configured to cooperate with a first cam follower carried by the tilting lever.
