Abstract
A vehicle driveline component with a differential mechanism and a lubrication device for lubricating the differential mechanism. The differential mechanism has a differential input member, which is rotatable about a differential axis, and a pair of differential outputs that are driven by the differential input member. The lubrication device includes at least one discharge port that is disposed in a volume within the differential input member and along the differential axis between the differential outputs.
Claims17
A vehicle driveline component comprising:
- a differential input member that defines a cavity, the differential input member being rotatable about a differential axis;
- a pin that extends into the cavity;
- a pair of side gears that are received in the cavity and which are rotatable about the differential axis;
- a differential pinion received in the cavity and being meshingly engaged to the side gears;
- and
- a lubricant reservoir that is received in the cavity and mounted to the pin, the lubricant reservoir defining an internal reservoir and a plurality of reservoir outlet ports that fluidly couple the internal reservoir to the cavity.
