Abstract
The utility model discloses a side front driving device for tractors, comprising a gear box and a front driving bridge. The gear box is installed with a gear box output shaft which is installed with a plurality of gear box output gears. The front driving bridge is provided with a central transmission and a differential gear. The back portion of the central transmission is connected with a transmission shaft, and the left side or the right side of the gear box is installed with a transfer case which is installed with a middle shaft parallel with the output shaft of the gear box and an output shaft of the transfer case. The middle shaft is installed with a middle gear jogged with a certain gear box output gear on the gear box output shaft. The output shaft of the transfer case is installed with a transfer case slipping gear jogged with the middle gear. The front end of the transfer case output shaft is connected with the transmission shaft, and the transfer case is installed with an operating framework for moving the transfer case slipping gear. For the transfer case and the transmission shaft is lifted from the bottom of the gear box to the left or the right side of the gear box, the interspaces from the ground of the tractor is increased, and the ideal agriculture requirement can be obtained.
Description
Technical field
The utility model relates to the layout of four-wheel drive tractor power drive shaft.
Background technology
Present four-wheel drive tractor, basically be to adopt mid-front driving device, high for the agriculture requirement ground Clearance, still passable, but,, had a strong impact on the trac. road clearance because the auxiliary gear box of middle front driving device, transmission shaft etc. all are arranged in bottom the trac. for higher just incompatible of agriculture requirement ground Clearance, will damage the crops of trac. bottom during work, the agronomy operation requirements that out of reach is desirable.
Summary of the invention
The technical problems to be solved in the utility model is for adapting to the requirement than the operation of crack, highland agronomy, solve little problem of middle front driving device ground Clearance, high trac. side front driving device of a kind of front driving device ground Clearance being provided.
For solving the problems of the technologies described above, the utility model comprises change speed gear box, front driving axle, and output shaft of gear-box is installed in change speed gear box, and a plurality of change speed gear box output gears are installed on the output shaft of gear-box; Front driving axle is provided with main gear, diff, the main gear rear portion is connected with transmission shaft, its constructional feature is in the left side of change speed gear box or right side auxiliary gear box to be installed, tween drive shaft parallel with output shaft of gear-box and auxiliary gear box output shaft are installed in the auxiliary gear box, be equipped with on the tween drive shaft with output shaft of gear-box on certain change speed gear box output gear ingear intermediate gear, be equipped with on the auxiliary gear box output shaft can with intermediate gear ingear auxiliary gear box shifting slide gear, the front end of auxiliary gear box output shaft is connected with transmission shaft, and the steering unit of stirring the auxiliary gear box shifting slide gear is installed on auxiliary gear box.
After adopting said structure, owing to auxiliary gear box and transmission shaft are risen to the left side or the right side of change speed gear box from original change speed gear box bottom, so just solved the two little problem of ground Clearance that causes in the change speed gear box bottom, thereby the ground Clearance of having improved trac. reaches desirable agriculture requirement.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, this trac. side front driving device comprises change speed gear box 5, and output shaft of gear-box 4 is installed in change speed gear box 5, and the rear end of output shaft of gear-box 4 is connected to the diff 7 on the back axle 9, thereby drive rear drive sprocket 8, a plurality of change speed gear box output gears 6 are installed on the output shaft of gear-box 4.Front driving axle 1 is provided with main gear, diff, front driving axle 1 connects front driving wheel 2 by left and right sides constant-velocity universal joint 15, the main gear rear portion is connected with transmission shaft 3 by universal-joint, sidepiece at change speed gear box 5 is equipped with auxiliary gear box 12, this auxiliary gear box 12 is installed in the left side or the right side of change speed gear box 5 by the sealing of bakelite pad, tween drive shaft 11 and the auxiliary gear box output shaft 14 parallel with output shaft of gear-box 4 are installed in the auxiliary gear box 12, be equipped with on the tween drive shaft 11 with output shaft of gear-box 4 on certain change speed gear box output gear 6 ingear intermediate gear 10, change speed gear box output gear 6 is a constant mesh gear with intermediate gear 10, be equipped with on the auxiliary gear box output shaft 14 can with intermediate gear 10 ingear auxiliary gear box shifting slide gears 13, auxiliary gear box output shaft 14 is a castellated shaft, auxiliary gear box shifting slide gear 13 is installed on the splined shaft section of auxiliary gear box output shaft 14, the front end of auxiliary gear box output shaft 14 is connected with transmission shaft 3 by universal-joint, the steering unit (not shown) of stirring auxiliary gear box shifting slide gear 13 is installed on auxiliary gear box 12, with of engagement and the disengagement of realization shifting slide gear 13 with intermediate gear 10, thus the connection and the cut-out of realization front driving axle 1 power.Present embodiment shows the configuration state of change speed gear box longitudinal axis transmission, adopts the change speed gear box of transverse axis transmission, as long as increase by one group of finishing bevel gear cuter between output shaft of gear-box 4 and tween drive shaft 11.
The principle of work of this device is as follows: from the power of driving engine, reach each fixing on output shaft of gear-box gear 6 through change speed gear box 5, output shaft of gear-box 4, thereby driven the rotation of each gear, intermediate gear 10 since with change speed gear box output gear 6 constant-meshes, thereby drive intermediate gear 10 and rotate.Auxiliary gear box shifting slide gear 13 is owing to be installed on the splined shaft section of auxiliary gear box output shaft 14, can before and after slide, auxiliary gear box shifting slide gear 13 is stirred auxiliary gear box shifting slide gear 13 with intermediate gear 10 engagements or separate under the manipulation of steering unit.During separation, power impassabitity transmission shaft 3 outputs to front driving axle 1, and front driving wheel 2 does not have power, can only make track adjusting wheel; During engagement, power reaches front driving axle 1 by auxiliary gear box shifting slide gear 13, auxiliary gear box output shaft 14, universal-joint, transmission shaft 3, front driving axle 1 reaches front driving wheel 2 by main gear, differential system, and front driving wheel 2 becomes drive wheel, forms four wheel drive with rear drive sprocket 8.
