Abstract
A compound transmission assembly is provided including a splitter gear and headset/fourth gear, both mounted on the input shaft. The splitter gear is provided with a minimal diametral float with respect to the input shaft in order to minimize splitter gear tipping while allowing substantially balanced torque splitting between opposing countershafts. The headset/fourth gear is mounted to the input shaft via a pair of oppositely tapered roller bearing sets disposed about the input shaft in order to prevent headset/fourth gear tipping. In this manner, gear hopout is prevented during PTO operation, and substantially balanced torque splitting is accomplished.
