    摘要： A differential carrier assembly having a differential, a differential carrier, and a differential bearing support. The differential carrier has a bearing support mount that may extend from a mounting flange of the differential carrier. The differential bearing support is mounted to the bearing support mount and receives a bearing assembly that rotatably supports the differential.

    摘要： The present invention relates to a driveline arrangement comprising a first driveline comprising a first electric machine and a first transmission arrangement, the first driveline being configured to propel a first pair of wheels at a speed range between zero speed and a maximum speed limit of the working machine, a second driveline comprising a second electric machine and a second transmission arrangement, the second driveline being configured to propel a second pair of wheels at a speed range between zero speed and a predetermined threshold speed limit of the working machine, wherein the predetermined threshold speed limit is lower than the maximum speed limit, and a control unit connected to the first and second drivelines, the control unit comprising control circuitry configured to control the second driveline to assume a disengaged state in which the second driveline is disconnected from propelling the second pair of wheels when a speed of the working machine exceeds the predetermined threshold speed limit.

    摘要： A torque distributor system (5) for distributing the torque coming from a power generator (1) of a vehicle to a plurality of axles (2a, 2b, 2c, 2d) of the vehicle, comprising a casing (6) adapted to define a space (7) configured to house a transmission (8), the casing (6) defining a plurality of openings (9, 10, 11, 12, 13, 14) configured to house respective power take-offs (15, 16, 17, 18, 19, 20) connected to each other by the transmission (8), a first power take-off (15) of the power take-offs (15, 16, 17 , 18, 19, 20) being connectable to the power generator (1) and at least one second (19) of the power take-offs (15, 16, 17, 18, 19, 20) being connectable to one or more of the axles (2a, 2b, 2c, 2d), the remaining power take-offs being isolated from the external environment by means of covers (21a, 21b, 21c, 21d) carried by the casing (6).

    摘要： An axle assembly (10) comprises a first axle shaft (26) orientated along a first axis of rotation (30), a second axle shaft (28) orientated along the first axis of rotation (30) with the first and second axle shafts (26, 28) extending in opposite directions, a first electric machine (14) orientated along a second axis of rotation (32) substantially parallel with the first axis of rotation (30). and a second electric machine (16) spaced from said the electric machine (14) and orientated along a third axis of rotation (34) substantially parallel with the first axis of rotation (30). Furthermore, a common gear reduction (40) is provided, which is rotatable about a fourth axis of rotation (104) and driven by the first and second electric machines (14, 16), and a speed change mechanism (44) is coupled to the common gear reduction (40) to change the rotational torque transferred to the first and second axle shafts (26, 28).
