Abstract
An axle assembly includes braking components that generate heat during braking applications. The axle assembly includes a housing defining a housing cavity and a rotating component mounted for rotation relative to the housing. A heat dissipation member is mounted along an external surface of the housing. Fluid flow cooperates with the heat dissipation member to cool axle components. The axle assembly preferably includes wet disc brakes having a brake housing defining a brake cavity in fluid communication with the housing cavity. The heat dissipation member preferably includes internal passages in communication with the housing and brake cavities. A pumping mechanism generates fluid flow through the internal passages and through the brake and housing cavities to dissipate heat generated during braking.
