Shift fork actuated position sensor

摘要

A shift fork assembly for a tractor transmission is disclosed wherein the shift fork assembly is mounted directly to the transmission cover to be removable therewith. The shift fork assembly includes shift forks mounted directly to the shift rails for movement therewith, the shift rail detent mechanism, the shift fork position adjustment mechanism and shift fork position sensors, and is removable from the transmission housing as a unit to facilitate the servicing thereof at a location remote from the transmission housing. The transmission cover onto which the shift fork assembly is mounted is also provided with a secondary cover to permit access to the shift fork position adjustment mechanism to allow positional adjustment of the shift forks relative to both the corresponding shift rail and the corresponding shift collar engageable by the shift forks. The shift fork position sensors are mounted on the secondary cover to be actuated directly by the shift forks and to be removable from the transmission housing as a unit for convenient servicing thereof.
