The conjuncted back axle change speed gear box of farm vehicle

Technical field

The utility model is the conjuncted back axle change speed gear box of a kind of farm vehicle.

Background technology

The employed change speed gear box of the conjuncted back axle of farm vehicle is generally the form of gear engage a gear at present, dumb, easy out of supply the losing rank of this engage a gear form gear shift.And the drive path of change speed gear box is unreasonable mostly, each gear is fully used, thereby causes the intensity of each gear unbalanced.

Summary of the invention

The purpose of this utility model is to design the conjuncted back axle change speed gear box of a kind of farm vehicle rational in infrastructure, and further makes it have the gear shift light and flexible, is difficult for out of supply losing rank and the rational performance of drive path.

The utility model has one to four and output shaft, its technical scheme at first is: the fourth gear ring gear is arranged on four, its respectively can with second gear driving gear, the third speed drive gear engagement on the fourth gear driving gear on one, three, at least one in second gear driving gear, the third speed drive gear is connected with three by the tooth hub sleeve.This structure of the present utility model is fully utilized the fourth gear ring gear, thereby has simplified the structure of change speed gear box dramatically, to reach purpose rational in infrastructure.

On the basis of said structure, the deceleration dual gear can be installed on four, its big gear wheel can with one-level deceleration driving gear engagement on one, miniature gears can with the double reduction ring gear engagement on three, thereby make structure of the present utility model more compact.

For make the utility model make the gear shift light and flexible, be difficult for out of supply lose rank and drive path reasonable, its operative gear can adopt following structure: the one-level deceleration driving gear is arranged on one, two reverse gearwheels are arranged on two, three shaft gears, third speed drive gear, second gear driving gear, double reduction ring gear are arranged on three, have on four with output shaft on the differential gear constant-mesh pass gear, fourth gear ring gear, deceleration dual gear, one grade of ring gear, four reverse gearwheels eventually; Big gear wheel constant-mesh in one-level deceleration driving gear and the deceleration dual gear, the miniature gears of deceleration dual gear and double reduction ring gear constant-mesh; Two shaft gears respectively with three shaft gears, four reverse gearwheel constant-meshes, four reverse gearwheels can by the tooth hub sleeve with spool be connected; Three shaft gears and one grade of ring gear constant-mesh, one grade of ring gear can be connected with its axle by the tooth hub sleeve; Second gear driving gear and fourth gear ring gear constant-mesh, and can be connected with its axle by the tooth hub sleeve; The third gear ring gear can be connected with its axle by the tooth hub sleeve.

And, wherein can establish five grades of driving gears on one and be connected with one, five grades of ring gear constant-meshes on it and four by the tooth hub sleeve.
