A powertrain for a vehicle includes an internal combustion engine and a transfer case. The transfer case includes a primary output shaft, an electric motor, and a planetary gear set. The primary output shaft receives engine torque from the internal combustion engine. The electric motor includes a rotor and a stator. The planetary gear set includes a sun gear rotatably fixed to the rotor, a ring gear, planet gears arranged radially between and engaging the sun gear and the ring gear, and a planet carrier coupled to the planet gears and rotatably fixed to the primary output shaft. The ring gear is selectively groundable for selectively transferring torque between the electric motor and the primary output shaft.

A vehicle is provided according to the disclosure. This vehicle comprises a gearbox, a longitudinal differential, a central tube module, at least one axle with an axle differential, wherein the axles are mounted on the central module and the longitudinal differential transmits the driving torque provided by the gearbox to the at least one axle, and a primary axle differential integrated into the powertrain between the longitudinal differential and the axle.

A differential with an overrunning clutch (ORC) assembly 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 (ORC) assembly selectively engages the roller cage assembly during an ORC condition to selectively couple torque between a ring gear and the first and second side hubs.

A vehicle includes a tandem axle system having an inter-axle differential and clutching assembly, a forward or first axle assembly, and a rear or second axle assembly. The inter-axle differential and clutching assembly includes a differential mechanism having first and second side gears and a clutch mechanism having a clutch member and an actuator assembly. At least one of the first axle assembly and the second axle assembly is in selective driving engagement with the inter-axle differential and clutching assembly.

A differential device includes a ring gear receiving a rotational driving force from a drive gear, a differential case rotating integrally with the ring gear around a predetermined axis, and a differential mechanism installed within a barrel part of the differential case. The ring gear includes a gear portion meshing with the drive gear, and a rim portion that is formed integrally with an inner periphery of the gear portion and is fitted, in a non-welded state, onto a maximum diameter outer peripheral portion of the barrel part or a predetermined outer peripheral portion having a smaller diameter than the maximum diameter outer peripheral portion. The rim portion has a to-be-fixed portion welded to the barrel part at a position spaced in an axial direction from a fitting part via which the rim portion and the barrel part are fitted, the position being further radially inward than the fitting part.

A vehicle driveline component having a differential input, which is rotatable about a differential axis, a differential gearset that is driven by the differential input, first and second differential outputs, which are rotatable about the differential axis, a first disconnect clutch and a second disconnect clutch. The differential gearset has a first gearset output and a second gearset output that are rotatable about the differential axis. The first disconnect clutch selectively couples the first differential output to the first gearset output, while the second disconnect clutch selectively couples the second differential output to the second gearset output.

A control device for a differential limiting device is provided. The differential limiting device limits at least one of a difference between rotational speeds of right and left wheels of a vehicle and a difference between rotational speeds of front and rear wheels of the vehicle. The control device includes an electronic control unit configured to obtain crosswind information on a crosswind to which the vehicle is to be subjected in a predetermined region located ahead in a direction of travel of the vehicle, and to perform control to generate a differential limiting force based on the crosswind information.

A method of controlling a drive axle system. The drive axle system may include first and second drive axle assemblies. A drive axle assembly may be disconnected by operating a wheel end disconnect to discontinue transmission of torque between a wheel assembly and a differential and by discontinuing the transmission of torque to the differential.

A vehicle having a longitudinal engine and permanent rear axle drive is proposed, which vehicle has an internal combustion engine and an electric machine, a transfer gearbox distributing drive torques as required to two drive axles, the transfer gearbox having three shafts, a main shaft serving as a drive shaft of the rear axle, a secondary shaft serving as a drive shaft for the front axle, and an intermediate shaft applying a torque, a shifting unit being installed between the reduction gear-box and the power summation gearbox.

The present disclosure is directed to an active transfer case equipped with a multi-plate clutch assembly, a clutch actuation mechanism configured to selectively engage the clutch assembly, a power-operated clutch actuator configured to control actuation of the clutch actuation mechanism, a power-operated actuator brake associated with the power-operated clutch actuator, and a control system configured to control actuation of the clutch actuator and the actuator brake while employing a preemptive check of the functionality of the actuator brake.
