A drive force control device, which controls a drive force distribution device that distributes a drive force to right and left rear wheels at variable distribution ratios, computes a steering angle-based turning radius determined in accordance with a steering angle, computes a limit turning radius, which is a minimum value of the turning radius with which the vehicle is turnable while keeping a stable travel state, in accordance with a vehicle speed, sets the larger one of the steering angle-based turning radius and the limit turning radius as a target turning radius, computes target rotational speeds for the right and left rear wheels on the basis of the target turning radius and the vehicle speed, and adjusts the ratios of distribution of the drive force to the right and left rear wheels such that actual rotational speeds of the right and left rear wheels approximate the target rotational speeds.

A clutch assembly includes a first clutch assembly having first clutch plates rotatably fixed to a first shaft and first carrier plates rotatably fixed to a clutch basket. The clutch assembly further includes a second clutch assembly having second clutch plates rotatably fixed to a second shaft and second carrier plates rotatably fixed to the clutch basket. The first and second clutch assemblies rotate about a common central axis and are actuated by a common actuator.

An all-wheel drive vehicle drivetrain can include an input member, first and second output members, a planetary differential, a first clutch, and a second clutch. The differential can include an internal gear, a carrier, a sun gear, and a differential gear set. The internal gear can be coupled to the input member to receive input torque about an axis. The carrier can be coupled to the first output for common rotation about the axis. The differential gear set can receive input torque from the internal gear and output differential torque to the carrier and the sun gear. The first clutch can be operable to selectively couple and decouple the sun gear with the second output member for common rotation. The second clutch can be operable to selectively transmit torque between the carrier and the second output member.

A vehicle includes a differential gear that transmits rotation of a propeller shaft to an axle. A differential lock switches the differential gear between a locked state and an unlocked state. A clutch is provided in a power transmission path between a prime mover and wheels of the vehicle. A controller controls an engaging force of the clutch during a moving start of the vehicle in accordance with which of the locked state and the unlocked state is selected by the differential gear.

A differential for an e-axle that includes an oil collector for enhancing oil distribution to the differential. Unlike conventional differentials, a differential in accordance with the present disclosure is not submerged in fluid. Rather, the oil collector collects fluid sprayed by other transmission components (e.g., a ring gear) and directs the fluid to the differential.

The present invention provides an improved inter-axle differential assembly to limit axle tire slip by limiting the excessive inter-axle differentiation between front and rear axles in a tandem axle set. The present invention provides an inter-axle differential assembly comprising a differential case including a cylindrical housing, an annular axial end surface connected to the cylindrical housing, an end cover plate wherein the annular axial end surface and the end cover plate include openings for receiving coaxial input and output shafts, a hollow chamber defined by the cylindrical housing, the annular axial end surface, and the end cover plate which houses differential gear assembly, and an unitary gear set extending continuously in the radial direction from the cylindrical housing.

A differential system provides an axle disconnect function, a synchronizer function, and it has the ability to transmit large amounts of torque and has a limited slip differential function in a compact and cost effective module.

A family of axle assemblies that employ a modular concept to maximize part commonality amongst the several axle assemblies. The axle assemblies have a housing assembly that employs a main housing that is formed from a casting that is common to all of the axle assemblies.
