  • Publication number: 20250343462
    Abstract: An electric drive unit with an electric motor, an input pinion, which is driven by an output shaft of the electric motor about a first axis, a pair of first gears, each of which is meshed with the input pinion and rotatable about a respective second axis, a second gear, which is meshed with the first gears and rotatable about a third axis, a third gear, which is driven by the second gear about the third axis, a fourth gear, which is meshed with the third gear and rotatable about a fourth axis, and a differential having a differential input, which is rotatably coupled to the third gear, and a pair of differential outputs that are driven by the differential input and rotatable about the fourth axis. The first, second, third and fourth axes are parallel to one another. The third axis is offset from the first and second axes.

  • Patent number: 8136997
    Abstract: A driveline assembly may include a driveline component housing, a pinion shaft located within the housing, a first bearing assembly, a second bearing assembly, a spacer assembly, and a load adjustment member. The spacer assembly may be located axially between the first and second bearing assemblies and may include first and second members. The first member may be axially fixed on the pinion shaft and may include an axial end defining a first generally conical surface. The second member may include a first axial end engaged with the second bearing assembly and a second axial end defining a second generally conical surface abutting the first generally conical surface. The load adjustment member may be axially displaceable relative to the pinion shaft to advance the second member axially along the first generally conical surface of the first member and adjust a preload on the second bearing assembly.
