Abstract: A gear train assembly includes a planetary gear set partially submerged in an oil bath and having a plurality of planetary gears mounted on a rotatable carrier. A plurality of sheaths having a hydrodynamic profile are mounted on the carrier to reduce the churning and turbulence created by the planetary gears as they enter the oil bath.

Abstract: The disclosure relates, in one aspect, to a friction brake cooling system for a machine. The cooling system includes at least one pump connected to at least one reservoir containing cooling fluid. A controller is configured to divert a cooling fluid flow through a valve to a first friction brake system and to a second friction brake system based on the use of the systems. In another aspect, the disclosure relates to a method of cooling a first friction brake system and a second friction brake system including diverting a flow of brake cooling fluid to the systems based on the use of the systems.

Abstract: An axle assembly includes an electric drive motor oriented along an axis and disposed within a central axle housing. The electric drive motor includes a motor housing having an engagement face perpendicular to the axis. A spindle assembly includes an external connection to the central axle housing and an internal engagement face that is perpendicular to the axis. A sealing member is in sealing contact with the engagement face of the motor housing and the internal engagement face of the spindle assembly.

Abstract: The present invention provides a wheel assembly for a work machine, the wheel assembly includes a hub defined about a central axis. The hub includes an inboard end, an outboard end and a rim-mounting flange. The rim-mounting flange includes an inboard surface, and outboard surface and an outer edge defined there between. The outer edge includes a groove extending toward the hub. A plurality of bores are disposed about the rim-mounting flange, each of the bores defines a bore diameter. A stud, having a shoulder defining a shoulder diameter is positioned in each of the bores. A retainer is positioned in the groove and holds each stud in its respective bore.
