A clutch for a Rear Drive Unit (RDU) selectively couples one of the half-shafts to an intermediate shaft. The clutch is actuated with a ball-ramp mechanism having a plate that rotates in response to rotation of a motor. In order to provide precise control of clutch torque capacity, a high gear reduction is desirable. Gear reduction is provided by a planetary gear set located co-axially with the clutched half-shaft. In addition to providing a relatively high gear ratio, this is more likely to fit into the available space without interfering with other components.

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 variable grille apparatus can adjust a flow rate of air flowing through a grille and upgrade an opening/closing operation when adjusting the flow rate of the air, thereby improving merchantability. In addition, by diversifying the opening/closing operation of the grille such as sequentially operating or simultaneously operating the opening/closing operation of the grille, it is possible to upgrade the opening/closing operation of the grille, diversify the exterior design, and secure the flow rate of air through the optimization of the structural arrangement.

A transfer for a four-wheel drive vehicle includes an input shaft, an output shaft, a high-low switching mechanism, an output member, a clutch, a locking sleeve, a screw mechanism, a transmitting mechanism, a drum cam, and a switching mechanism. The switching mechanism is configured to selectively switch between an H4L position and an L4L position in conjunction with rotational motion of the electric motor. The H4L position is a position in which a high-low sleeve provided in the high-low switching mechanism is in a position in which a high-speed gear is established in the high-low switching mechanism. The L4L position is a position in which the high-low sleeve provided in the high-low switching mechanism is in a position in which a low-speed gear is established in the high-low switching mechanism.

A shifter system assembly for a steering column constructed in accordance to one example of the present disclosure includes a shifter mechanism and a brake transmission shift interface (BTSI). The shifter mechanism receives a shift lever and selectively moves between a Park position and an out of Park position. The BTSI assembly comprises a BTSI pin assembly and a solenoid coil. The BTSI pin assembly includes a blocking pin, a solenoid pin and a coupler. The solenoid pin is separate and distinct from the blocking pin. The coupler couples the blocking pin and the solenoid pin. The BTSI pin assembly moves between an extended position and a retracted position. In the extended position the blocking pin inhibits movement of the shifter mechanism out of the Park position. In the retracted position, the blocking pin allows movement of the shifter mechanism to the out of Park position.

A drum cam is connected to a first annular member in a ball cam provided on a rear wheel-side output shaft. Furthermore, linear motion of a second annular member in the ball cam provided on the rear wheel-side output shaft is transmitted to a front wheel-driving clutch via a first transmission mechanism.

An extendable steering column includes a first jacket, a second jacket, an energy absorption strap, an indexing feature and a spring. The first jacket extends along an axis and the second jacket is disposed radially inward from the first jacket with the first and second jackets being in telescopic relationship to one-another. The locking shoe is in radial contact with the second jacket. The strap is fixed to the second jacket and disposed radially between the first and second jackets. The indexing feature facilitates a locked state and an unlocked state, and is carried between and defined by the strap and the locking shoe for telescopic adjustment of the steering column. The spring is disposed radially between the shoe and strap, and is constructed and arranged to bias the locking shoe radially away from the strap and toward the unlocked state.

An actuator device having a motor driven cam, a follower coupled to an output member and driven by the cam, and a controller for controlling operation of the motor. The cam has a first cam surface, a second cam surface and a lift portion between the first and second cam surfaces. The controller is configured to identify a predetermined point on the lift portion as the follower is moved relative to the cam along the lift portion toward the second cam surface. The controller identifies the predetermined point based on a rate of change in the position of the output member along an output member axis as a function of the rotational position of the cam about a cam axis. The controller controls operation of the motor based on the predetermined point to position the follower on the second cam surface.

A parking lock mechanism having a motor, an actuation shaft, an engagement cam, a release cam, a cam biasing member, a pawl member and a lock gear. The engagement cam has a first side, a second side and a perforation there through. An outer edge of the engagement cam has a contact portion and an engagement portion. The release cam has a first side, a second side and a perforation there through. An outer edge of the release cam has a release member and an engagement portion. The cam biasing member has a first end, a coil portion and a second end. The pawl member has a pivot perforation, an engagement end, a locking protuberance and a sensor protuberance. The pawl member is disposed adjacent the engagement cam and the release cam. The lock gear has a plurality of inner splines and outer teeth.
