FINAL SPROCKET DRIVE FOR TRACK-TYPE VEHICLES

摘要

A track-type vehicle comprises a track roller frame mounted on either side thereof and an endless track assembly mounted on each of the frames. Each frame further carries a final drive thereon, including at least one planetary gear set and a sprocket drivingly engaged with a respective track assembly. The power input to the final drive preferably comprises a hydrostatic motor for selectively driving a carrier of the planetary gear set which is attached to the sprocket for simultaneous rotation therewith.
