ABSTRACT:
A control system for a differential gear lock mechanism including a power transmission having at least two forward drives and a backward drive and a manually operated speed change lever associated with said power transmission.
The control system comprises a differential gear, an air tank containing compressed air therein, a conduit for connecting said air tank with said differential gear, a valve disposed in said conduit for selectively supplying compressed air to said differential gear when actuated, and a solenoid-controlled valve disposed in said conduit for interrupting air supply to said differential gear when actuated wherein said solenoid-controlled valve is adapted to be actuated when said speed change lever is shifted to a higher drive.
