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).
Claims4
A vehicle cross drive having a transverse axis, comprising:
- a ring gear (38);
- a pair of planetary gear assemblies (44,48,46,50) individually having a carrier (44,46) and a plurality of planetary gears (48,50) mounted to mesh radially within the ring gear (38);
- a pair of stationary annular support members (30,32) spaced along the transverse axis;
- and
- a pair of bearings (40,42) individually carried by the respective support member (30,32) radially within the ring gear (38) and rotatably supporting the ring gear (38), the support members (30,32) being of a construction sufficient for limiting transverse axial movement of the carriers (44,46).
