Abstract
Systems are provided for a differential of an electric powertrain. In one example, a system includes a portal axle coupled to only one side of a differential, the portal axle comprising a first axle and a second axle coaxial with one another.
Claims16
A system, comprising:
- a portal axle coupled to only one side of a differential, the portal axle comprising a first axle and a second axle coaxial with one another;
- the first axle comprising a first axle output gear coupled to a first jumper shaft gear, and the second axle comprising a second axle output gear coupled to a second jumper shaft gear;
- and
- an offset gear train coupled to accessory devices, the jumper shaft outputting to the offset gear train.
1 more element
An assembly for an electric powertrain, comprising:
- an input differential coupled to a first shaft and a second shaft concentric about an input axis extending through geometric centers of the input differential, the first shaft, and the second shaft;
- a jumper shaft comprising gears coupled to gears of the first shaft and the second shaft, and gears coupled to output gears arranged on separate output shafts;
- and
- one or more accessories coupled to the separate output shafts.
1 more element
An electric powertrain system, comprising:
- a differential coupled an output of an electric motor;
- a first shaft extending through a side of the differential;
- a second shaft extending through the side of the differential and coaxial with the first shaft, wherein the first shaft and the second shaft are concentric about a central axis of the differential;
- and
- a jumper shaft coupled to output shafts via a first jumper shaft gear and a second jumper shaft gear.
