Abstract
A wheel housing for a vehicle, such as a truck. The wheel housing includes a rotatable hub and stationary axle housing disposed within the hub. A wet brake assembly is disposed between the axle housing and the hub. The wet brake assembly includes a disc stack, which includes a plurality of friction plates that are coupled for rotation with the hub and that are separated from each other by a plurality of separator plates that remain stationary with the axle housing. The disc stack is cooled by coolant or oil that flows through a closed circuit. During a braking event, pressure spikes in the coolant circuit are alleviated by the placement of a compressible accumulator in the outlet passageway of the coolant circuit.
