A drivetrain component provides an electronically controlled, overrunning drivetrain disconnect, such as a differential with different operating modes. The drivetrain component includes a coupling member and a rotatable member rotating about the central axis. A first locking structure selectively mechanically couples the coupling member to the rotatable member, and a second locking structure selectively mechanically couples the coupling member to the rotatable member. The first locking structure engages a locking abutment of the rotatable member, and the second locking structure engages a locking abutment of the rotatable member.

A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.

A roller spring member for an overrunning clutch is provided. A first bridge connecting portion couples a bridge to a first spring central location of a first leaf spring. A second bridge connecting portion couples the bridge to a second spring central location of a second leaf. The roller spring member further includes at least one of, each of the first bridge connecting portion and the second bridge connecting portion including an undercut radius section, each of the first leaf spring and the second leaf spring being tapering from an associated one of the first spring central location of the first leaf spring and the second leaf spring central location of the second leaf spring to a first end and a second end, and each of the first leaf spring and the second leaf spring including a straight portion proximate the central locations.

A differential gear with an input side that can be rotated about an axis of rotation, which has a rotary drive contour for the rotary drive engagement with a drive wheel and at least one pinion gear that can be rotated about a pinion axle, and an output side that can be rotated about the axis of rotation, which has a first axle wheel and a second axle wheel which are in rotary drive engagement with the at least one pinion gear, wherein the input side has a rotary drive section on which the rotary drive contour is provided, and a support section on which the at least one pinion gear is arranged. The rotary drive section and the support section can optionally be brought into a rotary drive connection with one another by means of a shiftable pawl freewheel.

A differential with an always actuated overrunning clutch (ORC) is provided. The differential includes a first plain bearing end cap with an interior surface that forms a plain bearing interface with an outer surface of a first side hub. The first plain bearing end cap further has a first outer surface portion that engages a first end portion of a roller cage assembly. A second plain bearing end cap with an interior surface that forms a plain bearing interface with an outer surface of the second side hub is also included. The second plain bearing end cap further has a first outer surface portion that engages a second end portion of the roller cage assembly. The always actuated ORC engages the roller cage assembly during an ORC condition to couple torque between a ring gear and the first and second side hubs.
