ABSTRACT:
A tracked vehicle transmission provides reduced length between an engine output shaft and a transversely oriented main shaft which drives the vehicle tracks. The transmission includes a torque converter having an output shaft which extends across the main shaft. The primary side of the torque converter drives a steering unit and a power take-off shaft which includes a flow brake. The torque converter output shaft drives the main shaft through a gear train on the side of the main shaft opposite the converter. The gear train includes bevel gears which engage a pair of reversing clutches which drive planetary speed change gear sets. A pair of speed change gear sets may be positioned adjacent each of the reversing clutches or a single speed change gear set may be provided depending upon space requirements and installation conditions. The steering unit is mounted to the upper transmission casing as a single subassembly and is positioned above the main shaft in an area partially enclosed by the torque converter and the reversing clutches.
