Abstract
An electric axle system includes a first shaft for connecting to an electric motor and being rotatable about a first axis; a second shaft for connecting to a gearbox, the second shaft being coaxial with the first shaft and being rotatable about the first axis; and a gearing drivingly connecting the first shaft to the second shaft and having an effective rotation axis vertically below the first axis.
Claims19
An electric axle system comprising:
- a first shaft for connecting to an electric motor and being rotatable about a first axis;
- a second shaft for connecting to a gearbox, the second shaft being coaxial with the first shaft and being rotatable about the first axis;
- and
- a gearing drivingly connecting the first shaft to the second shaft and having an effective rotation axis vertically below the first axis,
- the gearing includes gears rotatable about axes consisting of the first axis, a second axis and a third axis, the third axis and the second axis being vertically below the first axis,
- the first axis, the second axis and the third axis together form a triangle, a geometric center of the triangle defining the effective rotation axis.
