In work, common is all the medium transmitted using balata belt as power.By function and purposes point agricultural, industry and specific use
Equal tractors；By structure type minute wheel formula, crawler type, boat tractor and self propelled chassis etc..So-called transfer case will exactly start
The device that the power of machine is allocated can output power to rear axle, or be output to front/rear axis simultaneously.From this angle
As can be seen that transfer case is actually an accessory on 4-wheel driven car.With the development of 4 wheel driven technology, transfer case is also carried out always
Change, and gradually formed the transfer case of different style, matched on the 4-wheel driven car of different demands, their basic principle and
Function is also all different.Gear box of tractor is disclosed in Chinese utility model patent specification CN202100695U
Operating mechanism includes: shift handle, handle bracket, flexible axle of shifting gears, block selecting flexible axle, flexible shaft bracket, block selecting plate, gear-shifting rocker arm, choosing
Keep off cross bar, T-shaped shaft universal-joint；Shift handle is fixedly connected with T-shaped shaft universal-joint, and T-shaped shaft universal-joint is mounted in handle bracket
On, shift handle can control relative to handle bracket, swing；Flexible axle of shifting gears, block selecting flexible axle both ends screwed pipe fix respectively
On handle bracket and flexible shaft bracket, it is connected with shift handle, block selecting plate, gear-shifting rocker arm by typed ball bearing pair；Block selecting plate is mounted on
On flexible shaft bracket, block selecting cross bar is installed on block selecting plate, block selecting cross bar can to the left, move right.Three can be realized using mechanism
Six gear selections can be achieved in group block selecting position and every group of two drive ranges altogether, meet more gear gearbox shift demands.It changes
Block handle, handle bracket are connect with the flexible shaft bracket being arranged on gearbox body, plate of shifting gears by flexible axle, rationally distributed, are used
It is convenient.Commonly a kind of transfer case handle structure mainly has transfer box assembly, rocker arm, pull rod, manipulation in Tractor Products at present
The composition such as handle.But the device has the disadvantage that (1) this structure is relatively easy, is directly connected with rocker arm with pull rod, when manipulation to
Upper lifting control crank, during pull rod movement, pull rod has a pivot angle, changes Impact direction, easily leads to clamping stagnation
Cause manipulation laborious.(2) due to being pull-type manipulation, lever is smaller, thus when manipulation driver need it is portable under push away, hand can be straight
It practices midwifery raw pause and transition in rhythm or melody sense, feel is bad.Therefore, research can optimize promotion handling comfort to pull-type operating mechanism
Technical solution meaning it is necessary.
Utility model content
For the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a kind of dialling for tractor
Lever formula transfer case operating mechanism.It has the characteristics that structure be simple and convenient to operate with it is safe and reliable.Manipulation can be made lighter
Just, more comfortable, to reduce pilot control fatigue strength.
In order to solve the above technical problems, the utility model provides a kind of fork shift rod-type transfer case manipulation for tractor
Mechanism.It includes transfer box assembly, rocker arm, pull rod, manipulation force transfering device, control crank, and transfer box assembly and steering force pass
Delivery device is located on tractor, and rocker arm is located on transfer box assembly, and rocker arm is connected with pull rod, and pull rod is scalability pull rod,
It is set on pull rod nut (preferably locking nut), pull rod is connected with manipulation force transfering device, manipulates and sets behaviour on force transfering device
Vertical handle, manipulation force transfering device includes connecting fork, bracket and control stick, and connecting fork one end is located on bracket, the other end and drawing
Bar is connected, and bracket is preferably u-bracket, and branch is erected on tractor, and control stick lower end is connected with connecting fork, under control stick
End is located on bracket, and control stick upper end sets control crank.
The control stick and connecting fork are located on bracket preferably by pin shaft.
Compared with prior art, the utility model generate beneficial effect be: due to the above structure, in use,
Manipulation force transfering device can change the direction of transfer of steering force, increase lever ratio, reduce steering force, keep manipulation lighter, behaviour
It is vertical more comfortable, to reduce pilot control fatigue.When being assembled, rod length can be adjusted as needed to change manipulation
The angle of handle, it is light comfortable to have reached manipulation, improves the reliability of operation.There is structure to be simple and convenient to operate and work for it
The features such as safe and reliable.
