摘要： A vehicle driveline component temperature control assembly utilizes compressed air or another fluid to cause air flow across an external portion of the driveline component. The airflow facilitates heat transfer or heat dissipation from within the driveline component to assist in maintaining the temperature of the component within an acceptable range. A supply of compressed air or other fluid communicates with at least one discharge device supported on an external housing of the driveline component. The discharge device includes at least one manifold having at least one opening through which the compressed air is delivered to create an airflow across the external surface of the housing. In one example, each discharge device comprises multiple, generally C-shaped manifolds that are secured in place and supported on the external surface of the housing. The inventive arrangement is particularly useful for off-highway vehicle driveline components such as axle and wet disc brake assemblies.

摘要： A system for controlling the temperature of a vehicle driveline component assembly includes using forced air to cool lubricant within the assembly. As heat builds up during braking applications, for example, a controller determines when additional cooling may be needed. An air source is activated to induce air flow through at least one flow passage supported relative to the housing so that the air flowing through the passage can absorb heat from the lubricant. In one example, the air flow passage is supported within the component housing. In another example, the air flow passage is associated with a heat exchanger supported external to the component housing in a strategic location on the vehicle or the housing, for example. A pump responsible for causing the air flow preferably also causes lubricant flow in a desired manner to facilitate heat dissipation.
