The special gearbox for the agricultural forklift can improve the practical functions of a transmission system, achieves the advantages of flexible and convenient shifting, safety and reliability of an industrial forklift gearbox, and can create important conditions for the economy and the energy preservation of the complete forklift because of very compact overall structure.
Description
Technical field:
The present invention relates generally to agricultural forklift operation field, relates in particular to the special-purpose gearbox of a kind of agricultural forklift (3T)
Background technique:
Current domestic agricultural forklift is generally continued to use the agricultural vehicle gearbox as variable ratio drive system, exists that to occupy the space big, and operating rate is unreasonable, and moment of torsion is little, and noise reaches defectives such as gearshift difficulty greatly, has had a strong impact on the market competitiveness.
Summary of the invention:
The object of the invention is exactly in order to remedy the defective of prior art, a kind of gearbox of agricultural forklift special use to be provided.It can not only promote the utility function of speed variator system, it is light flexibly to reach the gearshift that the industrial lift truck gearbox had, safe and reliable advantage, and because overall structure is very compact, it is nearly 20% to shorten length to compare the similar gear-box axle of industrial lift truck, for the economical and energy saving of car load has been created essential condition.
The present invention is achieved by the following technical solutions:
A kind of gearbox of agricultural forklift special use, include gearbox casing, be rotatablely equipped with input shaft, jack shaft, output shaft and reverse gear shaft in the described gearbox casing, it is characterized in that: fixed cover is equipped with driving gear on the described input shaft, fixed cover is equipped with the constant mesh gear with driving gear engagement on the described jack shaft, is set with the one grade of driving wheel that advances on the jack shaft on constant mesh gear right side successively, second gear driving wheel and idle pulley initiatively advance; Fixed cover is equipped with the passive idle pulley that meshes with the active idle pulley on the described reverse gear shaft, and described passive idle pulley both sides have down one grade of driving gear and the driving gear of falling the second gear to be fixedly set on the reverse gear shaft respectively; Forward gears synchronizer assembly and reverse gear synchronizer assembly fixedly are housed on the described output shaft, described forward gears synchronizer assembly both sides be set with advance one grade of driven wheel and advance the second gear driven wheel respectively with the one grade of driving wheel and the corresponding engagement of second gear driving wheel of advancing of advancing, described reverse gear synchronizer assembly both sides be set with down one grade of driven gear and the driven gear of falling the second gear respectively with one grade of driving gear and the corresponding engagement of the driving gear of falling the second gear.
Described gearbox is characterized in that: blocking respectively on the sliding sleeve of the sliding sleeve of described forward gears synchronizer and reverse gear synchronizer has shift fork, and shift fork is all stirred by the operating handle that is arranged on the casing.
The present invention directly is connected with engine clutch, and input shaft, jack shaft, reverse gear shaft, output shaft are installed in the gearbox casing, and motor drives driving shaft gear, and driving gear and constant mesh gear engagement driving are input to jack shaft with power.Through a pair of one grade of gear pair and the intermediate gear pair of advancing of advancing, the speed change that is meshed reaches the one grade of speed ratio that advances respectively: 7.70, and second gear speed ratio 3.14 advances; In addition through initiatively passive idle pulley engagement on idle pulley and the reverse gear shaft on the jack shaft,, reach the one grade of speed ratio 7.88 that falls back respectively with power input the fall back one grade of pair and the second gear pair that falls back; Second gear speed ratio 5.12 falls back.
The realization of shift speed change is after fixing by the involute splines of output shaft and synchromesh gear hub, to finish two jointly by synchromesh cone and shifter collar and advance second-speculation's function.Advance one grade, the second gear that advances falls back one grade, and needle bearing all is housed in the intermediate gear that falls back, and is free to realize dividing, move and use.Synchronizer gearshift light and flexible, safe and reliable.
The present invention adopts ingenious combination, and structure is very compact.Special-purpose gear-box axle is 250 millimeters to length overall, and width is 228 millimeters, highly is 204 millimeters.Compare with similar industrial lift truck gearbox, the special-purpose gearbox of this agricultural forklift takes up room and obviously reduces.Big intermeshing pressure angle, the transmission of displacement helical gear are all adopted in special-purpose gearbox design, and it is big to reach output torque, stable drive, the usefulness that noise is low.
Output shaft in the present invention adopts the design of disintegrating, and uses the thread connecting mode assembling.The tooth axle of jack shaft and reverse gear shaft cooperates employing thermal expansion press-loading process, and reliable in structure is reasonable, easy maintenance and reduction manufacture cost.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the mesh schematic representation between output shaft and reverse gear shaft cog.
