Abstract
An electrified vehicle assembly includes, among other things, an outer shaft that is rotatable about an axis. The outer shaft rotatably couples a motor of an electrified vehicle to a transmission component of the electrified vehicle. A shaft insert provides a conduit for a fluid and that blocks the fluid from flowing radially between the shaft insert and the outer shaft relative to the axis. The shaft insert includes a polymer-based material, a composite material, or both.
Claims13
An electrified vehicle assembly, comprising:
- an outer shaft that is rotatable about an axis, the outer shaft rotatably couples a motor of an electrified vehicle with a transmission component of the electrified vehicle;
- and
- a shaft insert that provides a conduit for a fluid and that blocks the fluid from flowing radially between the shaft insert and the outer shaft relative to the axis, the shaft insert includes a polymer-based material, a composite material, or both,
- wherein the shaft insert extends axially from a first end portion to an opposite, second end portion, wherein the first and second end portions are radially enlarged relative to other portions of the shaft insert to provide an annular channel between the shaft insert and the outer shaft, the annular channel axially between the first and second end portions.
An electrified vehicle shaft providing method, comprising:
- positioning a shaft insert within an outer shaft, the shaft insert having a fluid conduit and configured to block fluid from communicating radially between the shaft insert and the outer shaft, wherein the shaft insert includes a polymer-based material, a composite material, or both;
- and
- rotatably coupling together a motor of an electrified vehicle to a transmission component of an electrified vehicle using the outer shaft,
- wherein the shaft insert extends axially from a first end portion to an opposite, second end portion, wherein the first and second end portions are radially enlarged relative to other portions of the shaft insert to provide an annular channel between the shaft insert and the outer shaft, the annular channel axially between the first and second end portions.
An electrified vehicle assembly, comprising:
- an outer shaft that is rotatable about an axis, the outer shaft rotatably couples a motor of an electrified vehicle with a transmission component of the electrified vehicle;
- and
- a shaft insert that provides a conduit for a fluid, the conduit extending from a first axial end of the conduit to an opposite, second axial end of the conduit, the conduit configured to block fluid that has not passed through at least a portion of the conduit from flowing radially between the shaft insert and the outer shaft relative to the axis, the shaft insert includes a polymer-based material, a composite material, or both,
- wherein the shaft insert extends axially from a first end portion to an opposite, second end portion, wherein the first and second end portions are radially enlarged relative to other portions of the shaft insert to provide an annular channel between the shaft insert and the outer shaft, the annular channel axially between the first and second end portions.
