Abstract
A two speed planetary drive axle assembly comprises a differential carrier fixed over and extending within a drive axle housing. The carrier mounts a differential case connected by a pinion and ring gear to the engine driven propeller shaft. The case contains a differential mechanism connected between two drive axle shafts and constitutes a carrier for planet gears constantly meshed with an internal ring gear rigid with the differential case. The sun gear is in the form of a sleeve concentric with one of the drive axle shafts and selectively movable between two axially spaced operative positions within the axle housing. A fixed abutment is provided to limit axial movement of the sun gear in the direction of the differential mechanism to prevent the sun gear from contacting the differential mechanism. Additional abutment means limit movement of the sun gear in the other direction. The sun gear sleeve is thus positively stopped by the operating mechanism at each of the axially spaced operative positions.
