Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawing.
It is a kind of based on splined shaft transmission mountainous region crawler tractor levelling mechanism specifically include that leveling rack (1), leveling
Device (2) and walked frame (3)；
It is characterized by:
The leveling rack (1) includes upper layer rack (11), bearing block 1(12), bearing block 2(14) and oil cylinder seat (13),
Bearing block 1(11), bearing block 2(14) and oil cylinder seat (13) be welded on upper layer rack (11)；
The levelling device (2) includes hydraulic cylinder (25), driving lever (23), follower lever (27), bearing bar 1(22), load-bearing
Bar 2(28), pull rod (24), splined shaft 1(21) and splined shaft 2(26), the both ends of hydraulic cylinder (25) respectively with oil cylinder seat (13), main
Lever (23) articulated connection, the other end of driving lever (23) are connect with one end of splined shaft 1(21) by spline, driving lever (23)
It is hinged between follower lever (27) pull rod (24), one end of the other end and splined shaft 2(26) of follower lever (27) passes through spline
