The finally output of flexible axle of shifting gears connecting fork is connected to cab control mechanism by flexible axle of shifting gears；The upper end of outer gear-shifting rocker arm is equipped with
Splined hole is simultaneously connected with the horizontal gear level of gearbox.
Advantageous effect：
Since soft-axle fixation bracket is fixed on the side of gearbox and " Z " font rotating arm fixing bracket in the utility model
Be equipped with, it is easy for installation, make the height of gearbox operating mechanism reduce, former double rod manipulation on the basis of reduce about
Space, good hand touch have been vacateed in 110mm or so, the installation to be filled on special-purpose vehicle.
Gear selecting flexible axle connecting fork and flexible axle of shifting gears connecting fork are respectively equipped on soft-axle fixation bracket；So that gear selecting flexible axle and changing
Gear flexible axle can collect on a soft-axle fixation bracket, and manipulation is convenient.
Coordinate again on the rotating arm fixing bracket of " Z " font equipped with rotating arm, the wherein centre of rotating arm and " Z " font
Rotating arm is support bracket fastened to be flexibly connected below by rotation axis；Not only so that gear shift has spatial operation, but also block selecting is flexible.
When driver swings laterally control stick in driver's cabin（Gear selecting）, gear selecting flexible axle drive rotating arm it is flexible around rotation axis
It rotates, by connecting rod outer gear shift arm is driven to be moved along the left and right directions of gearbox, so as to drive the horizontal gear level of gearbox
It is flexible, complete gear selecting process；Gear selecting in place after, when driver is by forward/backward operation control stick（Gear shift）, flexible axle of shifting gears drive outer
Gear shift arm is rotated along splined hole, so as to which the horizontal gear level of gearbox be driven to rotate, completes gear selecting process.
The rational structure design of the utility model is not only easy for installation, saves space, but also whole operation process is smooth,
It is easy to operate, good hand touch.
