ABSTRACT:
An axle assembly including a differential gear set having a ring gear. The axle assembly includes a carrier assembly housing that contains the differential gear set and an arcuate fence disposed adjacent to the ring gear that connects to the carrier assembly housing. A moveable plate slidingly connects to the arcuate fence. The moveable plate has an open position, a closed position and a plurality of positions therebetween. The closed position is closer to the ring gear than the open position. The arcuate fence and/or the moveable plate may reduce churning of the lubrication to increase the cooling efficacy of the lubrication.
