The utility model is characterized in that the clutch and the speed changing shaft are arranged on the same plane; the speed changing shaft is provided with 4-gear and five-gear speed changing gear; the clutch driving shaft is provided with a reverse gear, a five-gear, two-gear, four-gear, one-gear, and three-gear driving gears. The utility model has the advantages of multiple speed changing gears, small speed changing ratio among the gears, compact structure, and reliable transmission.
Description
The utility model belongs to automotive field, particularly a kind of Agricultural automotive vehicle transmission system.
It is set to reverse gear, 1 grade, 2 grades and 3 grades existing Agricultural automotive vehicle transmission system, because the speed change gear is provided with few, 1 to 3 grade variable gear converter speed ratio up increases progressively by multiple, Agricultural automotive vehicle uses in the farmland need have several speed changes just can't realize that inconvenience has operated among a small circle.The agricultural three-wheeled motor vehicle of producing as Lanzhou Walking Traactory Factory of blue hunchbacked board is the third gear except that the variable gear that is provided with, between 1 grade of gear internal diameter and the transmission shaft bearing is housed, the gear displacement is easily caused in gear and axle gap in the course of the work, and engagement is unstable, and tooth damages in engagement easily.
The purpose of this utility model is the weak point at existing Agricultural automotive vehicle, has designed a kind ofly to satisfy many grades of speed changes, and has used firm Agricultural automotive vehicle change speed gear box.
The technical solution of the utility model is such.This change speed gear box comprises shifting fork bar combination, reverse gear variable gear, 1 grade of variable gear, 2 grades of variable gears, 3 grades of variable gears, variable shaft, shift fork, power output gear, clutch driving shaft, power take-off shaft and gearbox bodys.It is characterized in that clutch driving shaft; 3 grades, 4 grades, 5 grades variable shafts and reverse gear, 1 grade, 2 grades variable shafts are provided with at grade and are installed on the gearbox body.4 grades of variable gears and 5 grades of variable gears are housed on the variable shaft, reverse gear, 5 grades of driving gears, 2 grades of 4 grades of driving gears and 1 grade of 3 grades of driving gear are housed on the clutch driving shaft, between three driving gears spacer is housed.Power output gear, 3 grades of 4 grades of 5 grades of reducing gear and 1 grade of 2 grades of reducing gear of reverse gear are deceleration work formation by the internal key dress is solid on variable shaft.Can be connected with the reverse gearwheel axle by the key pin structure for the hydraulic oil pump assembly of power.On 3 grades, 4 grades, 5 grades variable shafts and the shift fork of different gears respectively is housed on the reverse gear, 1 grade, 2 grades variable shafts, the shifting fork bar combination forms supporting structure with the shift fork of different gears.The number of teeth of 1 grade of variable gear, 2 grades of variable gears, 3 grades and 4 grades of variable gears according to different speed change requests from low to high by the converter speed ratio design that increases progressively 60%; The number of teeth of 4 grades of variable gears and 5 grades of variable gears is by the converter speed ratio design that increases progressively 31%.
The utlity model has following advantage:
1. that the variable gear gear is set is many for the utility model, and the mutual converter speed ratio of different gear variable gears is less, makes it can satisfy multiple speed needs in actual use, has made things convenient for action need.
2. all do not have bearing installation between each grade of the utility model gear internal diameter and the transmission shaft, the gap is little in the course of the work for gear and axle, is not prone to gear displacement, the unstable phenomenon of engagement, has prolonged the working gear life-span, has increased reliability.
3. the utility model compact conformation, transmission uniqueness, saving horsepower, speed change and parts interchangeability are good, are the comparatively desirable short-distance transportation meanss in rural area or cities and towns, are particularly useful for using in the farmland.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
