Abstract: A seal for an axle shaft assembly which may be found in an automotive transmission or drive axle, is provided. The seal may accommodate significant axle deflection, while retaining a fluid-tight seal between multiple sealing surfaces. The seal may include dynamic flanges configured to seal against surfaces which are angled or orthogonal with respect to one another. The seal may also include one or more holes extending from an outer surface to an inner surface of the seal, such that a body of the seal forms a conduit which allows fluid, such as lubricating fluid, to flow through the seal.

Abstract: A powertrain system includes a housing that defines a reservoir. A shaft is rotatably disposed in the housing, and the shaft defines a bore. A cap is positioned to seal the reservoir. The cap defines an opening configured to supply lubricant to the shaft. The opening in the cap is positioned proximal the shaft to spray the lubricant into the bore. In one form, the cap has a nozzle, and the nozzle defines the opening configured to supply the lubricant to the shaft. The shaft is configured to rotate about a rotational axis, and the bore extends along the rotational axis of the shaft. The nozzle is aligned with the rotational axis of the shaft to spray the lubricant into the bore in order to lubricate bearings and other parts of the system.

Abstract: A lightweight towing cross member assembly 10 is disclosed. The cross member assembly 10 includes relatively lightweight front and rear cross members 12, 14, and reinforcement plates 16, 18 which offer added support to the assembly 10. The heavy-gauge, load-bearing plates 16, 18 are localized in the areas of high stress (i.e., the center of the assembly 10), and provide the assembly 10 with the load-bearing ability and towing performance of prior towing cross member assemblies, which are manufactured solely from heavy-gauge materials.
