ABSTRACT:
A track vehicle drive train, with a differential and outboard planetary gears driven by the differential has an outboard planetary housing containing the planetary gears. The planetary housing has a drive ring integral with it and extending circumferentially around it, upon which an externally undular sprocket is mounted directly. The housing is bell-shaped, and provides within it space to accommodate larger gears than housing known heretofore, which permits higher reduction in the outboard planetaries, which allows a lower reduction in the differential than has been possible heretofore with a standard sized sprocket.
