A vehicle driveline system for a vehicle is provided. The system comprises a differential having a differential housing connectable to an engine via a pinion, and two output shafts being connectable with respective wheel axles, and an electrical motor being selectively connected to the differential housing. The differential housing extends into a hollow shaft having a radial protrusion provided with engagement means, such as splines, for connecting with a shifting sleeve, wherein said shifting sleeve is configured to be actuated for connecting the electrical motor to said differential housing.

A method for controlling the safe operation of a rear axle of a set of combined axles powered by a motor vehicle, particularly for a vehicle designed to carry loads and which have 6×4, 8×4 or 10×4 type traction configurations, or tridem models formed by three drive axles. The method includes a set of steps and activities that ensure proper and safe operation of systems and mechanisms for uncoupling and raising a rear axle of a vehicle, and more specifically checking a status of certain operating parameters of the rear axle and of the vehicle itself in order to permit or prevent uncoupling and coupling, as well as raising and lowering of the rear axle of the vehicle.

A vehicle, system, and method for dynamic adjustment of a lead of an axle of a vehicle having a combustion engine for all-wheel drive of a front axle and a rear axle is provided. The system includes an electric motor and a summing gear configured to sum a drive power of the combustion engine and the electric motor. The summing gear has at least two gear elements. The at least two gear elements are magnetically coupled.

A work vehicle includes a power transmission unit having a differential device for transmitting power to left and right axles and a power transmission mechanism for transmitting power to the differential device, and a transmission shaft for transmitting power to the power transmission unit. The power transmission mechanism includes a first gear mechanism to which power from the transmission shaft is transmitted and a second gear mechanism for transmitting power from the first gear mechanism to the differential device.

A transfer case with an actuator for operating a two-speed transmission (i.e., range mechanism) and a clutch (i.e., mode mechanism). The actuator employs a motor-driven cam structure that coordinates the movement of a first fork, which is associated with the range mechanism, and a second fork that is associated with the mode mechanism. A resilient coupling is employed to provide compliance between the motor and the cam structure in the event that tooth-on-tooth contact inhibits the range mechanism from changing from a high-range mode and a low range mode or tooth-on-tooth contact inhibits the mode mechanism from changing between a two-wheel drive mode and a four-wheel drive mode. A sensor target and sensor are employed to identify the rotational positioning of the cam structure placement, which is indicative of the modes in which the transmission and the clutch are operating.

Methods and system are provided for locking a half shaft to a wheel hub to engage four wheel drive are disclosed. In one example, a wheel hub is locked to a half shaft via a radially expanding engagement mechanism. The radially expanding engagement mechanism is without grease and without springs.

A transfer includes: an input shaft; a motor; first and second output shafts; first and second planetary gear devices; an input switching unit; a transmission switching unit; and a distribution switching unit. Further, connection states of the input shaft, the first and the second planetary gear devices, the first and the second output shafts can be switched to a plurality of modes including first, second, and third modes by the input switching unit, the transmission switching unit, and the distribution switching unit.

An integrated pinion/bearing/coupling (PBC) assembly for use with a hypoid gearset in power transfer assemblies of motor vehicles having mounting features and venting features, The integrated PBC assembly includes a hollow pinion unit made of steel and including a pinion shaft segment and a pinion gear segment, and a coupling unit having a hub segment made of aluminum. A brazing sleeve is used to braze the aluminum hub segment of the coupling unit to the steel pinion shaft segment of the pinion unit.
