Abstract
The utility model discloses a zero-offset driving axle of a loader, which is composed of a driving axle shell assembly 1, a main gear flange 8, a main gearbox assembly 2, a left and a right brakes 3, 3', a left and a right braking drums 4, 4', a left and a right wheel-edge speed reduction devices 5, 5', a left and a right half axles 6, 6' and a left and a right end covers 7, 7'. An axial line of a driving gear 2a, the axial line of the main gearbox assembly 2 and the axial line of a cross axis 16 of a planet gear are on the same axial line. The center of the main gear flange 8 is arranged in the right center of the driving axle shell assembly 1. Because the utility model enables the zero offset distance of the axial line of the driving gear and the axial line of the main gearbox assembly to be achieved and the equal length of both ends of the driving axle shell is kept, the main gear flange is arranged in the right center of the driving axle assembly. Thus a loader can have the advantages of steady driving, low noise and high driving efficiency, and the left and the right half axles of the driving axle assembly can be mutually interchanged. Thus fabrication, assembly and maintenance are more convenient, and the utility model can be particularly adapted to the requirements of low speed and big twist pitch of the loader.
Description
Technical field
The utility model relates to the improvement of loader drive axle, and specifically a kind of loader zero offset drive axle is applicable to 0.5-3.0 tonne loader.
Technical background
Loader belongs to engineering machinery, and along with the needs of rapid economy development and national basis construction and city-building, loader is extensively promoted the use of, and brings into play the effect of wanting emphatically.At present, its main gearbox assembly of the employed drive axle of loader all has certain offset, be the axis of the axis of driving gear and main gearbox assembly and planetary gear " ten " word axle axis to a lateral deviation from, can not overlap on an axis, have certain distance.The existence of this offset makes the axis of driving gear and the axis of drive axle assembly also have certain offset, thereby when power transmission shaft connected with the drive axle assembly, power transmission shaft can not be parallel with loader car body axis, must deflection.Make thus the junction transmission not steadily, noise is high, transmission efficiency is low, can not satisfy loader low speed large torque, stable drive, requirement that noise is low.At present, some manufacturing firm is for solving the problem of power transmission shaft deflection, employing is designed to not isometric scheme with driving axle housing and solves, thereby make the driving gear axis be positioned at the drive axle center, this scheme makes left and right half not isometric, therefore left and right half can not be exchanged, and gives and manufactures, assembles and keep in repair and all bring many inconveniences.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, stable drive, noise is low, transmission efficiency is high and can adapt to loader low-speed big characteristics, be convenient to manufacture and assemble the loader zero offset drive axle of maintenance.
For reaching above purpose, the technical scheme that the utility model adopted is: this loader zero offset drive axle, by the driving axle housing assembly, flange of cardinal tooth, main gearbox assembly, a left side, right brake, a left side, right brake drum, a left side, right hub reduction device, a left side, a right axle shaft and a left side, right end cap constitutes, a left side, right axle shaft passes the left side of driving axle housing assembly respectively, a right-hand member and a left side, right hub reduction device is connected, flange of cardinal tooth is fixed on the axle head position of driving gear of main gearbox assembly, the axis that it is characterized in that driving gear, the axis of the axis of main gearbox assembly and planetary gear " ten " word axle on an axis, the center that is centered close to the driving axle housing assembly of flange of cardinal tooth, during use power transmission shaft is connected with flange of cardinal tooth, its operating principle is: the main frame dynamic torque passes to flange of cardinal tooth by power transmission shaft, after the main gearbox assembly deceleration, change direction of rotation and drive driven gear and differential casing rotation, differential casing drives planetary gear " ten " word axle and planetary gear is given axle shaft gear with transmission of power, axle shaft gear is by a left side, right axle shaft is passed to a left side respectively with power, right hub reduction device (adopting NGW planetary reduction gear drive mechanism), after slowing down, pass to wheel hub, thereby wheel rolling is advanced.The utility model is also implemented by following measure: described main gearbox assembly, constitute by final drive casing, driving gear, driven gear, main, driven gear is arc tooth conical gear, the axis of driving gear and the central lines of final drive casing, driving gear supports by two taper roll bearings in the main pinion bearing and the cylinder roller bearing in the final drive casing, and be assembled into one with final drive casing, driven gear by by the tooth bolts assemblies on differential casing; Flange of cardinal tooth is linked and packed on the axle head position of driving gear by spline, and is fastened as one by main teeth nut packing ring and main teeth nut; Differential casing is connected with the final drive casing assembling by the taper roll bearing at two ends, planetary gear " ten " word axle is housed in differential casing, " ten " word direction that follows star gear " ten " word axle is assembled planetary gear respectively, two axle shaft gears are loaded on respectively in the hole at differential casing two ends, and mesh with planetary gear; Insert respectively in the splined hole of axle shaft gear of and arranged on left and right sides the inner of left and right half.By adjusting the adjustment nut of and arranged on left and right sides, make the taper roll bearing at differential carrier two ends obtain reasonable pretightning force, make two taper roll bearings in the main pinion bearing obtain rational pretightning force by adding, subtract main pinion rim sheet and ball bearing washer.
The beneficial effects of the utility model are: compare with the loader drive axle of present use, because it is main, driven gear has adopted arc tooth conical gear, make the axis of driving gear and the axis of main gearbox assembly realize the zero offset distance, and kept the driving axle housing two ends isometric, making the axis of driving gear and the axis of driving axle housing is the zero offset distance, thereby make the protruding image position of main tooth in the center of drive axle assembly, the power transmission shaft that is connected also is positioned at the center of drive axle assembly, power transmission shaft is parallel with the loader car body, solve power transmission shaft and connected the deflection problem, make the loader stable drive, noise is low, the transmission efficiency height, and make a left side in the drive axle assembly, right axle shaft is isometric, interchangeable, make its manufacturing, assembling, keep in repair conveniently, can adapt to the requirement of loader low speed large torque especially.
