TRANSMISSION AND VEHICLE WITH TRANSMISSION
The disclosure relates to a transmission comprising an input shaft, a first output shaft, a second output shaft, a first planetary gear set, and a second planetary gear set which is connected to the first planetary gear set. Each of the planetary gear sets comprises multiple elements. The input shaft, the two output shafts, the planetary gear sets, as well as the elements thereof are arranged and designed such that—a torque introduced via the input shaft is converted and is distributed to the two output shafts in a defined ratio, and the development of a sum torque is prevented. At least one element of the first planetary gear set is rotationally fixed to another element of the second planetary gear set. Another element of the second planetary gear set is secured to a rotationally fixed component.

AXLE ASSEMBLY
An axle assembly with a housing, an annular gear, a bearing, a differential, and a pair of output shafts. The housing has an annular hub. The annular gear is received in the housing. The bearing, which is a four-point angular contact bearing, supports the gear for rotation about an axis relative to the housing and has an inner bearing race, which is mounted on the annular hub, and an outer bearing race that is fixedly coupled to the annular gear. The differential is received in the housing and includes an input member, which is coupled to the annular gear for rotation therewith, and a pair of output members that are rotatable relative to the input member about the output axis. Each of the output shafts is coupled to an associated one of the output members for rotation therewith. One of the output shafts extends through the annular hub.

LEFT-RIGHT WHEEL DRIVING DEVICE
A left-right wheel driving device (10) includes: a casing (15) including a reservoir (18) that stores oil; a suction port (19) that is disposed on the reservoir (18) and that sucks the oil from the reservoir (18); and two gears (34) that are each having helical teeth, that are supported so as to be rotatable about a rotating shaft (13) at least in one direction (D), that are provided on a power transmission path that transmits power to left and right wheels of a vehicle, and that are spaced apart from each other. The suction port (19) is positioned between the two gears (34). Each of the gears (34) is offset from the suction port in an axial direction of the rotating shaft (13), being in a state of being partially immersed in the oil stored in the reservoir (18). The helical teeth of each of the gears (34) extend in the one direction (D) and in a direction that departs from the suction port (19).
ELECTRIC DRIVE UNIT
The present document relates to an electric drive unit, comprising: a stator configured to produce a stator magnetic field, at least a first rotor including first rotor windings, the first rotor windings for instance including multi-phase windings, and at least a first inverter electrically connected with the first rotor windings and configured to produce an electric current in the first rotor windings for producing a first rotor magnetic field. The stator magnetic field is configured to interact with the first rotor magnetic field to exert a torque on the first rotor. The present document further relates to a method of operating the electric drive unit.
METHOD FOR CONTROLLING A DRIVING DYNAMICS FUNCTION OF A WORKING MACHINE
A method for controlling a driving dynamics function of a working machine with at least two vehicle axles. A current actual wheel rotational speed of at least one wheel is detected and sent to a control unit for comparison with an acceptable wheel rotational speed of the same wheel and wheel slip is calculated from that comparison. The control unit emits a control signal to lock at least one differential gear system if the wheel slip has an unacceptable value. For the differential gear system (4, 5, 6, 7, 8) concerned, an unlocking control signal is periodically emitted and the wheel rotational speeds are compared afresh. A control signal to lock the differential gear system concerned is emitted again if the value of the wheel slip is still unacceptable, and a trajectory is detected with reference to detection elements, along which the value of the wheel slip of the at least one wheel has been unacceptable.
VEHICLE DRIVE APPARATUS
A transmission mechanism is provided with an output gear drivingly coupled to at least one of a pair of output members and placed coaxially with the pair of output members. A direction in which a rotating electrical machine and an inverter device are arranged side by side in an axial view is defined as a first direction. A direction perpendicular to both an axial direction and the first direction is defined as a second direction. A first output member that is one of the pair of output members is placed between the rotating electrical machine and the inverter device in the first direction, at a position in the second direction where both the rotating electrical machine and the inverter device are placed. The output gear is placed in such a manner as to overlap each of the rotating electrical machine and the inverter device in the axial view.
VEHICLE DRIVE APPARATUS
A vehicle drive apparatus includes: a rotary electric machine disposed on a first axis; a differential gear mechanism disposed on a second axis; an output member disposed on the second axis; an inverter device; and a case. The case is a single-piece case internally including: a first housing chamber housing the rotary electric machine; and a second housing chamber housing the inverter device and divided from the first housing chamber with a partition. At least a specified portion of the output member is housed in the first housing chamber. A location of the specified portion in an axial direction overlaps with the rotary electric machine. The partition is provided between the specified portion and the inverter device.
