Abstract
A brake mechanism for braking an axle shaft rotatably supported within an axle housing. A pair of arcuate brake pads are pivotally pinned within the axle housing such that each of the arcuate brake pads can pivot from an brake position engaging the axle shaft and a free position allowing the axle shaft to rotate freely. The arcuate brake pads are spring biased to the free position allowing axle rotation. A simply pulley system is arranged within the axle housing to allow remote actuation of the arcuate brake pads forcing the brake pads into the brake position to frictionally engage the axle shaft thereby providing a braking force. The axle shaft may be splined to engage a corresponding reverse spline profile formed on the inner surface of the arcuate brake pads to provide a positive braking force to lock the shaft preventing rotation. The brake arrangement is preferably employed to brake an input shaft in a differential assembly or in any drive shaft of a transfer case.
