A coupling comprises a pair of clutch end members, a clutch center member disposed between the clutch end members, and an actuator coupled to one of the end members. Each end member includes concentric V-grooves disposed on a respective face thereof. The center member is axially movable between the end members, and includes a pair of opposing surfaces. One of the opposing surfaces includes concentric V-grooves configured to mesh with the V-grooves of one of the end members. Another of the opposing surfaces includes concentric V-grooves configured to mesh with the V-grooves of another of the end members. The actuator is configured to simultaneously couple the end members to the center member by urging the V-grooves of both of the end members into engagement with the V-grooves of the center member.

An electric powertrain includes a first electric motor that has an uninterrupted connection with a drive shaft of a vehicle. The electric powertrain further includes a second electric motor that has an interruptible connection with the drive shaft. In one form, this interruptible connection includes a clutch. The electric powertrain further includes a first gear train in the form of a first planetary gear and a second gear train in the form of a second planetary gear. The clutch in one variation includes a positive clutch in the form of a dog clutch. The dog clutch has a clutch suspension configured to deflect a clutch collar when gearing is misaligned during shifting.

A clutch unit for a powertrain of a motor vehicle is disclosed, comprising a torque input component acting as a drive element and a torque output component acting as an output element, which can be connected to transmit a torque to the torque input component through a clutch which can be switched through friction elements, the clutch having two partial clutches by which the torque input component and the torque output component can be connected so as to transmit a torque, in which one of the two partial clutches is configured as a positive-fit clutch and the other of the two partial clutches is configured as a friction clutch. In addition, the disclosure relates to a hybrid module with a first drive machine the output shaft of which can be connected through such a clutch unit to an output shaft of a second drive machine or a transmission input shaft.

An adjusting device (1) for a motor vehicle interior component includes a housing (3) in which a rotational element (2) is provided in a rotatable manner about a rotation axis (100). A first locking element (21) is rotationally fixed to the rotational element (2), and a second locking element (22) is provided on the housing (3). The locking elements are reversibly movable relative to each other from a locked situation, in which the locking elements (21, 22) interact with each other in a positively and/or non-positively engaged manner, into an adjustment situation, in which said positive and/or non-positive engagement is released. The adjusting device has an adapter plate (23) which is provided in a rotatable manner relative to the rotational element (2) and the housing (3) and at least temporarily drives a locking element (21, 22).

A clutch control device is provided for a four-wheel drive vehicle for transmitting drive force to the rear wheels. The clutch control device includes a dog clutch and a friction clutch, and a controller that controls the engagement and disengagement of the dog clutch and the friction clutch. In this clutch control device, the four-wheel drive hybrid vehicle includes a disconnected, two-wheel drive mode and a connected, four-wheel drive mode. When a driver's foot is lifted off an accelerator in a low-speed region when the connected, four-wheel drive mode is selected, the 4WD control unit maintains the connected, four-wheel drive mode while the brakes are not depressed, and shifts the mode to the disconnected, two-wheel drive mode when the brakes are depressed.
