  • Patent number: 11845329
    Abstract: An electric axle assembly includes a drive housing and a drive assembly. The drive assembly is housed in the drive housing and engages with wheels of a vehicle for rotating the wheels to move the vehicle along a ground surface. The drive assembly includes a drive input, one or more gearsets, and axle shafts. The one or more gearsets transfer motive force from the drive input to the axle shafts.
    Type: Grant
    Filed: August 2, 2022
    Date of Patent: December 19, 2023
    Assignee: Allison Transmission, Inc.

  • Patent number: 11820217
    Abstract: An axle assembly for frame rail vehicles is described herein. The axle assembly also includes a drive unit housing that includes an interior cavity enclosing first and second electric machines, a common gear reduction, a differential gear set, and a speed change mechanism with the first and second axle shafts partially disposed within the interior cavity and extending out of the drive unit housing. The drive unit housing includes a central cavity, a lower cavity, a first machine cavity, and a second machine cavity. The central cavity includes the common gear reduction and the axis of rotation of the first and second axle shafts. The lower cavity accumulates a volume of gearbox fluid with the speed change mechanism at least partially immersed in the lower cavity. The first machine cavity includes the first electric machine and the second machine cavity includes the second electric machine.

  • Patent number: 11820216
    Abstract: An axle assembly for frame rail vehicles is described herein. The axle assembly includes a first axle shaft and a second axle shaft orientated along a first axis of rotation. A first electric machine is orientated along a second axis of rotation and a second electric machine is spaced from the first electric machine and orientated along a third axis of rotation. A differential gear set is disposed about the first axis of rotation and is coupled to and driven by a common gear reduction to transfer rotational torque from the first and second electric machines to the first and second axle shafts. A speed change mechanism is coupled between the common gear reduction and the differential gear set to change the rotational torque transferred to the first and second axle shafts.
