  • Axle assembly with axle housing assembly having air scoops for cooling
    Patent number: 8715127
    Abstract: An axle assembly having a heat sink coupled to an axle housing assembly for ejecting heat from the axle assembly. The heat sink includes an air channel having a body coupled to the carrier housing assembly such that heat is conducted from the carrier housing assembly to the body of the air channel and an air passage formed in the body and having an open leading end and an open trailing end, the leading end being positioned relative to the carrier housing assembly to permit air flowing over the axle assembly when the axle assembly is in use to be received into the air passage such that heat is conducted from the body to the air flowing through the air passage, and the trailing end being positioned relative to the carrier housing assembly to permit air received in the air passage to be expelled through the trailing end.

  • Vehicle driveline component having heat sink for increased heat rejection capabilities
    Patent number: 8585526
    Abstract: An axle assembly that includes an axle housing assembly, a differential disposed in the axle housing assembly, an input pinion, a pair of axle shafts and a heat sink. The input pinion is coupled to the axle housing assembly and is configured to transmit a rotary input to the differential. The axle shafts are coupled to the differential and housed in the axle housing assembly. The heat sink is coupled to the axle housing assembly and is formed of a material having a thermal conductivity that is greater than that of the axle housing assembly. The heat sink does not consist entirely of a chrome plating, a zinc plating or a cadmium plating.
