A disconnect apparatus including a first clutch member and a second clutch member in selective engagement with the first clutch member. The disconnect apparatus also includes a cam mechanism and a sensor assembly. The cam mechanism includes an axially movable first cam member and an axially fixed second cam member. Wherein the sensor assembly generates a pulse pattern which is utilized to determine a position of the first cam member, and thereby a state of the disconnect apparatus.

A vehicle drivetrain for a vehicle including a transmission configured to move the vehicle with a surface engaging traction member and a final drive assembly configured to drive the surface engaging traction member. The final drive assembly includes a drive assembly coupler. A transmission coupler is operatively connected to the transmission and disposed between the transmission and the drive assembly coupler. The transmission coupler includes a first position engaged with the drive assembly coupler and a second position disengaged from the drive assembly coupler. An actuator is operatively connected to the transmission coupler and is configured to move the transmission coupler between the first position and the second position. The actuator, in one embodiment, includes a worm drive having a worm gear configured to move the transmission coupler along a longitudinal direction of the transmission. The worm gear rotates about an axis inclined with the longitudinal direction.

A vehicle drive unit that provides improved power transfer to a differential input member of a differential assembly. The vehicle drive unit is configured with an interlock system that is configured to inhibit the supply of electrical power from a source of electrical power if certain predetermined conditions are not met.

A transfer case for use in a four-wheel drive vehicle and having a clutch assembly disposed on a front output and a pass-through rear output arrangement. The front output is a front output shall. The rear output is established by directly interconnecting a transmission output shaft to an end segment of a rear propshaft. A transfer assembly is driven by the transmission output shaft and can be selectively coupled to the front output shaft via the clutch assembly.

A clutch actuator unit that includes an abrasion compensation device and removes an adhesive force between a clutch disc and a flywheel by using a diaphragm spring to press the clutch disc against the flywheel and by using a fork to push a first side of the diaphragm spring may include an outer member including a groove and a female screw portion, a push rod pushing against a first side of the fork, an inner member including a male screw portion screwed into the female screw portion, including a rotation center portion of a rear end portion thereof in which a support portion is formed, and including a first gear portion, a fixed guide member guiding the outer member, a pushing member including a second gear portion meshed with the first gear portion, an actuator employing an actuator rod to push or pull the pushing member, and a controller controlling the actuator.

An actuation mechanism for a clutch, includes: an actuation element designed to be applied with an actuating force and to be shifted in an actuation direction by same; a transfer element designed to carry out a shift in the actuation direction; and a compensation mechanism designed to apply a reinforcing clamping force for the frictionally engaged transfer of the actuating force between the transfer element and the actuation element, when an actuating force is applied to the actuation element. The compensation mechanism has a friction element and a counter surface which are designed to bring about the reinforcing clamping force via a frictional connection when applying the actuating force. The friction element and the counter surface are designed to generate the reinforcing clamping force via a supporting force resulting from a deflection of the actuating force. The reinforcing clamping force has at least the value of the supporting force.
