LOW LOSS LUBRICATION SYSTEM

摘要

A low loss vehicle differential axle lubrication system has a differential housing having axle gearing, where a lubricant is void of anti-foaming agents, but may have foaming agents. The lubricant may be churned/aerated to form foam, turbulence, and bubbles. System members make mechanically interacting contact while immersed in the lubricant. Mechanically interacting contact is either mechanically meshing or loaded contact. The lubricant presents a lower magnitude drag force on each member. The system may have a beater, a gas pressure jet or nozzle, and/or a surface characteristic that generate the foam, turbulence, and bubbles. These elements contribute to better heat transfer, less wear on parts, and smoother operation of a differential with less loss of efficiency resulting from reducing oil drag. Consequently, the differential housing may be sealed without a circulating pump or external heat exchanger, thereby avoiding the addition of oil throughout the system's life.
