Patent ID: 8739932

Claim:
A hydraulic filtering, cooling and lubrication system for use with a vehicle including an engine, a pump coupled to the engine and a plurality of axles, the system comprising: a manifold in fluid communication with the pump and an axle, the manifold located downstream of the pump and upstream of the axle, a filter coupled to the manifold, a filter differential bypass in communication with the filter, wherein the filter differential bypass is located within the manifold and is configured to open and provide oil directly to the axle during a cold start of the engine, if the filter is plugged, or any consistent period of time when the pressure across the filter exceeds a predetermined pressure, a plurality of control valves downstream of the filter, the plurality of control valves located within the manifold, wherein the filter differential bypass is configured to route oil away from the plurality of control valves during a cold start of the engine, if the filter is plugged, or any consistent period of time when the pressure across the filter exceeds a predetermined pressure, the manifold in fluid communication with a heat exchanger of the vehicle, the manifold including a heat exchanger supply passage for supplying oil to the heat exchanger, the manifold including a heat exchanger return passage for returning oil from the heat exchanger, the manifold including an axle supply passage for supplying oil to the axle, the oil configured to lubricate and cool the axle or wet disc brakes of the axle, the manifold including an axle return passage for returning oil from the axle, at least one of the plurality of control valves configured to circulate returning oil through the manifold, and wherein the manifold is a closed oil circuit separated from any other manifold or axle.
