Abstract
The utility model discloses a forklift driving axle housing axle housing welded structure of improvement, including taking turns limit back shaft, axle housing and sector plate. The inner outer end with the axle housing of wheel limit back shaft through the welding of first welding seam together, the inner of sector plate be a lantern ring, this lantern ring cup joints in combination department of round limit back shaft with the axle housing, between the outer wall of side of the sector plate lantern ring and wheel limit back shaft through the welding of second welding seam together, pass through the third welding seam and weld and be in the same place between the outer wall of another side of the sector plate lantern ring and axle housing. Because the utility model discloses because weld the back through first welding seam will taking turns limit back shaft and hub, treat welding seam cooling back, fix the sector plate on first welding seam again, second welding seam and the third welding seam on sector plate both sides weld simultaneously, and the deformation cancel each other out on messenger both sides further reduces the deflection of this sector plate for the sector plate is difficult to take place the thermal deformation, has to weld advantage firm, long service life.
Description
Technical field
The utility model relates to a kind of engineering truck, particularly relates to a kind of driving axle of forklift shell welding structure of improvement.
Background technology
As shown in Figure 1 and Figure 2, traditional wheel limit pivot shaft 1 ', axle housing 2 ' and quadrant 3 ' are fixed by the first weld seam 4 ', the second weld seam 5 ', by the bolt on quadrant 3 ', hub and wheel limit pivot shaft 1 ' are fixed in frame, wherein the second weld seam 5 ' will take turns limit pivot shaft 1 ', axle housing 2 ' and quadrant 3 ' three be fixed, produce very large thermal stress therebetween, quadrant 3 ' is caused to produce comparatively large deformation, may make the bolt on this quadrant 3 ' cannot be relative with frame upper screwed hole, make quadrant 3 ' to be arranged in frame smoothly; Not only be simultaneously subject to taking turns the moment of flexure of limit pivot shaft 1 ' due to the second weld seam 5 ' but also be subject to the combined action of moment of torsion of quadrant 3 ', weld seam easily ftractures, and service life is low.
Summary of the invention
The purpose of this utility model is the driving axle of forklift shell welding structure providing a kind of firm welding, long service life.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of driving axle of forklift shell welding structure of improvement, comprises wheel limit pivot shaft, axle housing and quadrant; Described wheel limit pivot shaft is inner passes through the first weld seam weld together with the outer end of axle housing, the inner of quadrant is a collar, this collar is socketed in the junction of wheel limit pivot shaft and axle housing and is positioned on the first weld seam, by the second weld seam weld together between a side of the quadrant collar and the outer wall of wheel limit pivot shaft, the quadrant collar between another side and outer wall of axle housing by the 3rd weld seam weld together.
The groove that between described pivot shaft the inner, wheel limit and the outer end of axle housing, Formation cross-section is triangular in shape, the first weld seam is filled up in this groove, makes the torus that the first weld seam Formation cross-section is triangular in shape.
After adopting such scheme, because the utility model is after wheel limit pivot shaft and hub being welded by the first weld seam, after weld seam cooling, then welded seam position is carried out " postwelding processing "; Then, welding of quadrant and axle housing is carried out, namely, be fixed on by quadrant on the first weld seam, simultaneously second weld seam on quadrant both sides and the 3rd weld seam weld simultaneously, and the distortion on both sides is cancelled out each other, the deflection of further this quadrant of reduction, makes quadrant that thermal deformation be less likely to occur.In addition, quadrant symmetric design of the present utility model, favourable welding, welding quality easily ensures, has that welding process is simple, firm welding, welding effect are good, cost is low, the advantage of long service life.In addition, bearing seat locking groove of the present utility model adopts casting, does not need machinework, saves material, saves overhours.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.

Fig. 1 is the front elevation commonly using driving axle of forklift shell welding structure;
Fig. 2 is that Fig. 1 is along K direction view;
Fig. 3 is axonometric drawing of the present utility model;
Fig. 4 is cutaway view of the present utility model;
Fig. 5 is that Fig. 4 is along A direction view.
Detailed description of the invention
As shown in Figure 3-Figure 5, the utility model is a kind of driving axle of forklift shell welding structure of improvement, comprises wheel limit pivot shaft 1, axle housing 2 and quadrant 3.
The inner outer end with axle housing 2 of described wheel limit pivot shaft 1 mutually against, groove 12, first weld seam 4 that Formation cross-section is triangular in shape is between filled up in this groove 12, makes the torus that the first weld seam 4 Formation cross-section is triangular in shape.Described wheel limit pivot shaft 1 outer end that is inner and axle housing 2 is welded 4 by the first weld seam and is connected together.
The inner of described quadrant 3 is a collar 31, this collar 31 is socketed in the junction of wheel limit pivot shaft 1 and axle housing 2 and is positioned on the first weld seam 4, first weld seam 4 is wrapped up, between a side of quadrant 3 collar 31 and the outer wall of wheel limit pivot shaft 1, weld 5 by the second weld seam be connected together, by the 3rd weld seam 6 weld together between another side and the outer wall of axle housing 2 of quadrant 3 collar 31.
Emphasis of the present utility model is just: the both sides of the quadrant collar are all welded.
The above, be only the utility model preferred embodiment, can there be various shape in the cross section of weld seam, therefore the scope of the utility model enforcement can not be limited with this, namely the equivalence change done according to the utility model claim and description with modify, all should still belong in scope that the utility model patent contains.
Claims (2)
1. a driving axle of forklift shell welding structure for improvement, is characterized in that: comprise wheel limit pivot shaft, axle housing and quadrant; Described wheel limit pivot shaft is inner passes through the first weld seam weld together with the outer end of axle housing, the inner of quadrant is a collar, this collar is socketed in the junction of wheel limit pivot shaft and axle housing and is positioned on the first weld seam, by the second weld seam weld together between a side of the quadrant collar and the outer wall of wheel limit pivot shaft, the quadrant collar between another side and outer wall of axle housing by the 3rd weld seam weld together.
2. the driving axle of forklift shell welding structure of improvement according to claim 1, it is characterized in that: the groove that between described pivot shaft the inner, wheel limit and the outer end of axle housing, Formation cross-section is triangular in shape, first weld seam is filled up in this groove, makes the torus that the first weld seam Formation cross-section is triangular in shape.
