Problems solved by technology

[0005] In order to overcome the single-axle dynamic load capacity of 13 tons and greater dynamic load of the steering drive axle, the overall cast steel axle housing is not strong in impact bearing capacity, incapable of bearing overturning moment, inflexible in design and manufacture of deformation, and heavy in weight. To solve the problem, the present invention provides a welded rectangular cross-section steering drive axle housing with simple and beautiful overall appearance, high strength and rigidity, good toughness, strong impact resistance and light weight

Embodiment 1

[0037] like figure 1 As shown, a steering drive axle housing A includes an upper cover plate 1, a lower cover plate 2, four side plates 3, two steel rings 4, and two steering forks 5. The materials of the upper cover plate 1, the cover plate 2, the side plate 3 and the steel ring 4 are all steel plates. The middle part of the upper cover plate 1 and the lower cover plate 2 is a U-shaped structure facing opposite, the bottom is arc-shaped, and the two sides of the arc are transition slopes. Two steel rings 4 are welded in the middle of the arc, and the steel rings 4 have the effect of reinforcing ribs, which can strengthen the strength of the shell and improve the torsional rigidity. The outer diameter of the steel ring 4 fits with the arcs of the side plate 3 , the upper cover plate 1 and the lower cover plate 2 respectively. The side plate 3 is adapted to the shape of the upper cover plate 1, the lower cover plate 2 and the steel ring 4, the two ends of the side plate 3 are...

Embodiment 2

[0040] like figure 2 As shown, a steering drive axle housing B includes an upper cover plate 1, a lower cover plate 2, four side plates 3, two steel rings 4, and two steering forks 5. The materials of the upper cover plate 1, the cover plate 2, the side plate 3 and the steel ring 4 are all steel plates. The middle part of the upper cover plate 1 and the lower cover plate 2 is a U-shaped structure facing opposite, the bottom is flat, and the inclined surfaces on both sides of the bottom are in arc transition with the bottom plane and the straight line sections at both ends of the cover plate. Two steel rings 4 are welded in the middle of the U shape, and the steel rings 4 have the effect of reinforcing ribs, which can strengthen the strength of the shell and improve the torsional rigidity. The outer diameter of the steel ring 4 is attached to the arc of the side plate 3, the upper cover plate 1 and the lower cover plate 2 respectively. The side plate 3 is adapted to the shap...

Abstract

The invention relates to an axle case for a turning drive vehicle axle. The axle case comprises an axle case body and a turning fork which are connected in a manner of gas metal arc welding (GMAW) and is characterized in that: the axle case body is formed by welding an upper cover plate, a lower cover plate, lateral plates and steel rings; the central parts of the upper cover plate and the lower cover plate have U-shaped structures in opposite orientations; the bottoms of the U-shaped structures are in the shapes of an arc shape and a plane shape; the middle parts of the U-shaped structures are welded with two steel rings; the outer diameters of the steel rings are firmly combined with the lateral plates, the upper cover plate and the lower cover plate respectively; the lateral plates are adaptive to the shapes of the upper cover plate, the lower cover plate and the steel rings; lateral surfaces at both ends of each lateral plate are mutually vertical to the upper cover plate and the lower cover plate; and the cross section of the axle case body is rectangular. The axle case has the advantages of simple and artistic whole appearance, high strength, high rigidity, high toughness, high impact resistance and light weight.

Description

technical field [0001] The invention relates to a heavy-duty axle housing, in particular to a steering drive axle housing. [0002] Background technique [0003] At present, integral cast steel axle housings are generally used in domestic integral steering drive axles, which can fully meet the load-bearing requirements when used on steering drive axles with a single-axle dynamic load capacity of less than 10 tons. However, if the steering drive axle with a single-axle dynamic load capacity of 13 tons and greater dynamic load adopts an integral cast steel axle housing, because the whole is cast steel, its impact resistance is not strong. When in use, breakage accidents are prone to occur. Therefore, the steering drive axle with a single-axle dynamic load capacity of 13 tons or more generally does not use an integral cast steel axle housing. In addition, due to process and cost reasons, it is not easy to design and manufacture cast steel axle housing variants, which are onl...
