Abstract
An axle drive mechanism for an automotive vehicle whose transmission is connected to a continuously coupled axle. The mechanism has a drive shaft forming part of another axle, a drive wheel rotatably mounted on the drive shaft and operatively connected with the transmission and the selectively connected axle, a clutch between the wheel and the shaft actuatable for rotatably coupling the wheel and the shaft to selectively engage the other axle, and a parking brake for the axles. The parking brake comprises a housing, a first brake between the wheel and the housing, and a second brake between the shaft and the housing. A common actuator is provided for both brakes, thereby immobilizing both of the axles independently of the operation of the clutch.
