Abstract
A split axle drive mechanism for a part-time four-wheel drive vehicle comprises a fist axle shaft connected to one side gear of a differential, a first output member arranged to be connected to the first axle shaft, a second axle shaft axially slidably connected to the other side gear, a second output member arranged to be connected to the second axle shaft, a clutch mechanism disengageable for disconnecting the first axle shaft from the first output member when the vehicle is in a two-wheel drive mode and engageable for connecting the first axle shaft to the first output member when the vehicle is in a four-wheel drive mode, a connecting rod axially slidably disposed in the axle shafts and having one end operatively connected with the clutch mechanism and another end connected with the second axle shaft, a coupling mechanism for connecting the second axle shaft to the second output member in response to engagement of the clutch mechanism, and a shift mechanism arranged to axially translate a clutch sleeve of the clutch mechanism between disengaged and engaged positions. A pneumatic actuator is arranged to operate the shift mechanism, and the coupling mechanism is arranged to connect the second axle shaft to the second output member after engagement of the clutch mechanism under control of the pneumatic actuator.
