ABSTRACT:
A transversely compact and serviceable vehicle cross drive for a track-type tractor or the like includes a ring gear (38), a pair of planetary gear assemblies (44,48,46,50) mounted to mesh radially within the ring gear (38), a pair of annular support members (30,32), and a pair of bearings (40,42) individually carried by the respective support member (30,32) and rotatably supporting the ring gear. Advantageously the support members (30,32) limit transverse axial movement of the planetary gear assemblies (44,48, 46,50).
