In general, agricultural machinery mainly includes tow tractor and working cell, and a kind of common structural union is
It is connected by hitch structure with working cell at the rear portion of tow tractor, this hitch structure is usually Hooks coupling universal coupling knot
Structure, and this universal joint structure usually has certain length, is connected to meeting when between gearbox rear portion and working cell
There are a biggish clearance space, the reductions that will lead to transmission stability in this space between gearbox and working cell
With the migration of equipment center of gravity, result in the need for additional apparatus assembly to make up these defects, if can by this clearance space it
Between spacing reduce, then drawbacks described above can be made up in root.
Summary of the invention
The technical issues of the utility model is solved is to provide a kind of gearbox designs of crawler tractor, solve existing
There is the defects of technology.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of gearbox designs of crawler tractor, including gear box, the gear box rear portion are provided with ten thousand
To shaft coupling mounting structure, and output shaft of gear-box is set in gear box two sides symmetric position, meanwhile, the two of gearbox
Side rear portion two sides are extended with supporting plate structure, supporting plate structure described in two sides and gear box rear belt Hooks coupling universal coupling mounting structure
Section collectively constitute a cross section be U-shaped fork structure, and the U-shaped fork structure on the outside of be provided with power output shaft,
Coaxial sleeve is equipped with driving wheel and driving wheel on the power output shaft, and the driving wheel is driven with the output shaft of gear-box
Connection, and the driving wheel be then connected with the crawler belt of crawler tractor go forward side by side action edge export.
In the present invention, in order to improve transmission stability and utmostly save cost, the supporting plate structure is used
Semicircle or four/three-arc supporting plate structure.
In the present invention, the material of the supporting plate structure is consistent with gear box material, and and gear box
It is integrally formed.
In the present invention, outer flange and ribs are provided on the outside of the supporting plate structure.
In the present invention, the driving wheel is set on the inside of power output shaft, with the output shaft of gear-box it
Between realized by the engagement of gearbox or transmission gear group power output connect.
The utility model has the advantages that the utility model discloses a kind of gearbox designs of crawler tractor, this crawler tractor
Gearbox designs pitch structure by the way that a U-shaped is arranged in gearbox tail portion, and universal by installing on the inside of this U-shaped fork structure
Axis device shortens the effect in gap between tow tractor and working cell to realize, can be effectively dilatory to traction by equipment center of gravity
Machine side is mobile, and improves the stability of equipment operation, while easy for installation, easily operated, and performance is stablized, and can effectively reduce volume
Outer counter weight construction and the use for increasing steady structure reduce equipment production cost and equipment operation energy consumption.
Detailed description of the invention
