Abstract
A temperature controlled axle cooling system and method is disclosed. Axle hydraulic circuits cool oil circulating through vehicle axles, and sensors monitor axle temperatures. Pumps are activated to circulate the oil through the axle circuits based on the axle temperatures. Each axle circuit can be a separate closed-loop hydraulic system, not sharing fluid with any other vehicle or axle hydraulic systems. All axle cooling system pumps can be activated when any axle temperature exceeds a high threshold. All pumps can be deactivated when all axle temperatures are below a low threshold. Each pump can be activated and deactivated based only on that axle's temperature. The axle cooling system pumps can be driven by motors powered by the main vehicle hydraulic system flow. A valve can be controlled based on axle temperature to allow main vehicle hydraulic system flow. Multiple pumps can be driven by a single motor.
