摘要： Methods and systems are provided for operating a vehicle that includes a torque vectoring electric machine. In one example, torque output of a torque vectoring electric machine is adjusted to reduce driveline torque disturbances when the torque vectoring electric machine is activated. The torque output is adjusted in response to a speed difference between a wheel speed and a speed of the torque vectoring electric machine.

摘要： A differential drive system includes an electric motor for generating an electric motor torque and an input planetary gear-set operatively connected to the electric motor to receive the electric motor torque. The input planetary gear-set has first, second, and third members. The first member receives the electric motor torque, the second member provides a first input torque in a first rotational direction in response to the electric motor torque, and the third member provides a second input torque in a second rotational direction, opposite the first direction, in response to the electric motor torque. The system also includes a first output gear-set operatively connected to the input planetary gear-set, and providing a first output torque in response to the first input torque. The system additionally includes a second output gear-set operatively connected to the input planetary gear-set and providing a second output torque in response to the second input torque.

摘要： A differential device for a 4-wheel-drive vehicle wherein a portion of a drive power source drive force transmitted to left and right main drive wheels is transmitted to left and right auxiliary drive wheels through a propeller shaft which is disconnectable from a power transmitting path between the main drive wheels and drive power source, the differential device distributes the drive force from the propeller shaft to the auxiliary drive wheels, and selectively connects and disconnects the propeller and an output shaft to and from each other, the output shaft. The differential device includes a side oil seal between the output shaft and a casing, a side bearing adjacent to the seal in an output shaft axial direction such that the output shaft is rotatably supported by the casing via the bearing, and an oil slinger axially adjacent to the bearing so the slinger is rotated with the output shaft.

摘要： An output transfer group is disclosed for use with a mobile machine. The output transfer group may have a housing, an input yoke extending from the housing and configured to receive an input torque, a first output yoke extending from the housing and configured to provide a first output torque, and a second output yoke extending from the housing and configured to provide a second output torque. The output transfer group may also have a gear train disposed within the housing and connecting the input yoke to the first and second output yokes. The gear train may create a torque reduction between the input yoke and the first and second output yokes, and includes a lockable differential located downstream of the torque reduction.

摘要： A vehicle differential inversion assembly for splitting the torque of the vehicle power source two ways to opposite sides of the vehicle, to a set of wheels; a left wheel and a right wheel. The wheels are supported by respective independent left and right suspensions allowing vertical travel of each wheel. The assembly features a differential module for splitting the torque two ways. The differential module is disposed between the left wheel and the right wheel and has a left side output and a right side output. The outputs spin at opposed directions. A left output axle couples with the left side output and extends to the left of the differential module. A right output axle couples with the right side output and extends to the right of the differential module. A left wheel axle is cross-coupled with the right output axle by a right inversion joint disposed at a distance to the right of the differential module. The left wheel axle extends toward and turns the left wheel. A right wheel axle is cross-coupled with the left output axle by a left inversion joint disposed at a distance to the left of the differential module. The right wheel axle extends toward and turns the right wheel. The right inversion joint and the left inversion joint provide for angular articulation of the left wheel axle and the right wheel axle, respectively, thereby allowing the vertical travel of each wheel.
