Forced air cooling system for vehicle driveline components

摘要

A vehicle driveline component temperature control assembly utilizes compressed air (40) or another fluid to cause air flow across an external portion of the driveline component (22). 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 (50) having at least one opening (52) 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.
