Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Specific embodiment
4 speed power out-put device of a kind of tractor as shown in Figure 1, including gearbox 1, transmission input shaft 2 are mounted on
The middle part of gearbox 1, running gear transmission shaft 3 and power output driving shaft 4 are located at up and down the two of transmission input shaft 2
Side and parallel with transmission input shaft 2.Driving gear there are four being set on transmission input shaft 2,3 He of running gear transmission shaft
Power output driving shaft 4 be equipped with the one-to-one driven gear of the driving gear, running gear transmission shaft 3 and power are defeated
Four driven gears are designed on driving shaft 4 out, can be realized 4 fast power outputs, three axis are in symmetrical structure in gearbox,
Compact and reasonable.
In the present embodiment, four driving gears be successively IV grade driving gear 5 of the axial alignment on transmission input shaft,
III grade of 6, II grades of driving gear, 7, I grades of driving gear driving gear 8, II grade of driving gear 7, I grades of driving gears 8 and speed changes
Case input shaft 2 is linked together, the spline 9 that IV grade of driving gear, 5, III grades of driving gears 6 and the transmission input shaft 2 are equipped with
It is cooperatively connected, four master gears drive rotation by transmission input shaft.
Driven gear is IV grade driven gear of the axial alignment on running gear transmission shaft 3 and power output driving shaft 4
10, III grade of 11, II grades of driven gear, 12, I grades of driven gear driven gear 13.IV grade of driven gear, 10, I grades of driven gears 13 with
The external splines 15 that 14 outer peripheral surface of bushing is equipped with is cooperatively connected, and is designed in IV grade of driven gear, 10, I grades of 13 centre bores of driven gear
The internal spline cooperated with external splines 15.14 gap of bushing is socketed on axis body, when IV grade of driving gear and I grade 13 turns of driving gear
IV grade of driven gear 10 and I grade of driven gear 13 dally when dynamic.III grade of driven gear, 11, II grades of driven gears 12 are slide teeth
Wheel, described, the involute spline 16 that balladeur train and axis body are equipped with is cooperatively connected, the external splines 15 and axis on the bushing 14
