Abstract
The utility model discloses a transmission case on a light truck, which comprises a main transmission case and an auxiliary transmission case, wherein the auxiliary transmission case is connected with the front end of the main transmission case. The auxiliary transmission case connected between the main transmission case and the engine is used as a link for power transmission, so that when the light truck runs on an uneven road, the impact force on the gear generated by the engine torque force can not directly act on the gears in the main transmission case, but is born by the auxiliary transmission case gears with simpler structure and lower cost, thereby indirectly protecting the safe and reliable use of the main transmission case and greatly reducing the maintenance cost of the light truck in later stage; and meanwhile, the auxiliary transmission case is easy and flexible to operate in the process of gear shift and speed change, thereby ensuring the smooth completion of the speed change process. The structure of the utility model is especially suitable for various light trucks with large impact force and high load capacity.
Description
Technical field
The utility model relates to a kind of automobile-used gearbox, and particularly a kind of serviceability is good, simple to operate is used for gearbox on the light truck.
Background technique
Along with social development and progress, agricultural light truck enters in our life more and more.According to market survey, wearing and tearing often appears in existing light truck or the parts that damage mainly concentrate on gearbox, gearbox is under steam because rotating speed is very fast, on the road that jolts, the impact force that gear in the gearbox is subjected to is bigger, and gear wear is serious, even causes whole gearbox to damage, scrap, increase the user cost of light truck greatly, had a strong impact on the working life of light truck.For avoiding the generation of this situation, the user mode of improving gearbox just becomes problem to be solved in the utility model.
Summary of the invention
In view of above-mentioned deficiency of the prior art, the utility model aims to provide a kind of gearbox on the light truck of being used for that can effectively prevent gearbox excessive wear, easy to use, reliable performance.
The utility model is achieved through the following technical solutions:
A kind of gearbox that is used on the light truck comprises main-gear box, also comprises an auxiliary transmission, and auxiliary transmission is connected the front end of main-gear box.
Described auxiliary transmission comprises casing, lever, is positioned at the driving mechanism of casing, lever is positioned at the casing top, lever is used to adjust the coupled condition of driving mechanism, and the input end of driving mechanism is connected with the input shaft of on-board engine and main-gear box respectively with output terminal.
Described driving mechanism comprises change gear, driving gear, the duplicate gear that has internal tooth and is positioned at a main shaft and a countershaft on the center line, driving gear is fixed on the inner end of main shaft, the center of driving gear is provided with through hole, change gear is connected the countershaft inner end by spline, change gear is relative with driving gear, lever can be stirred change gear and move on countershaft, and duplicate gear is positioned at the below of main shaft and countershaft, and duplicate gear can be connected with change gear with driving gear respectively.
Described driving gear and main shaft are structure as a whole.
The gearbox that is used on the light truck described in the utility model; utilization is connected auxiliary transmission between main-gear box and the motor as a powerdriven link; the impact force that the road surface when walking engine torsion that jolts produces gear make light truck on can not act directly on gear in the main-gear box; and it is simple relatively by structure; lower-cost auxiliary transmission gear is born; indirect protection the safety of main-gear box; the reliable use; the later maintenance cost of light truck is reduced greatly; simultaneously; the shift of auxiliary transmission; the throw-over process operation is simple; use flexibly, guaranteed finishing smoothly of speed-change process.Its structure is particularly suitable for using on the various light trucks big in impact force, that carrying capacity is more.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of gearbox that is used on the light truck described in the utility model comprises main-gear box and auxiliary transmission, and auxiliary transmission is connected the front end of main-gear box, and auxiliary transmission is used to protect main-gear box, prevents the main-gear box excessive wear.
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
Described auxiliary transmission comprises casing 3, lever 4 and is positioned at the driving mechanism of casing 3.Lever 4 is positioned at casing 3 tops, and lever 4 is used to adjust the coupled condition of driving mechanism, changes the transmission speed ratio of driving mechanism.Driving mechanism comprises change gear 7, driving gear 5, the duplicate gear 6 that has internal tooth and is positioned at a main shaft 1 and a countershaft 2 on the center line, and the outer end of main shaft 1 is connected with on-board engine, and the outer end of countershaft 2 is connected on the input shaft of main-gear box.Driving gear 5 is fixed on the end of main shaft 1 inboard, driving gear 5 and main shaft 1 are structure as a whole, center at driving gear 5 also is provided with pit, the driving gear 5 of integrative-structure can increase stability of transmission, and the pit that is positioned at driving gear 5 centers provides connection space can be connected with driving gear 5 for change gear 7 time.Change gear 7 is connected countershaft 2 inner ends by spline, and change gear 7 is relative with driving gear 5, and lever 4 can be stirred change gear 7 and move back and forth on the spline of countershaft 2.Duplicate gear 6 is positioned at the below of main shaft 1 and countershaft 2, and the big I of the modulus of two gears is set as required on the duplicate gear 6, and to change the size of transmission speed ratio, two gears on the duplicate gear 6 are connected with change gear 7 with driving gear 5 respectively.
In the installation process, auxiliary transmission is connected between main-gear box and the on-board engine, reduces the direct impact of the engine torsion that the main-gear box internal gear is subjected to when running up.The rotating power of motor at first is delivered on the driving gear 5 by the main shaft on the auxiliary transmission 1, when the needs tick-over, driving gear 5 will rotatablely move by duplicate gear 6 and be delivered on the change gear 7 that is connected on the countershaft 2, change gear 7 drives countershaft 2 rotations by spline again, thereby the input shaft that drives main-gear box rotates.When the needs high speed rotating, promote lever 4, driving change gear 7 moves to the left, because change gear 7 is provided with internal tooth, driving gear 5 is provided with the pit that matches with change gear 7, so change gear 7 can move to driving gear 5 one sides easily, and is meshed with driving gear 5, finish the transmission process that driving gear 5 directly drives change gear 7, improved the rotating speed of countershaft 2 outputs.And the duplicate gear 6 that originally is connected with change gear 7 can be thrown off with change gear 7 this moment, an idle running in the casing 3 that is rotated in along with driving gear 5.
