[0032] See also Figures 1 to 6 This embodiment provides an integrally molded, integral bridge housing comprising a housing 20, a rear cover 12, a flange ring 13, and four filler plates 30. The housing 20 is made of a rectangular steel tube, closed at both ends. Each closed end of the housing 20 is provided with a shaft head. Specifically, the rectangular steel tube has a rectangular cross-section. The center of the housing 20 is cylindrical, with convex sides. A through-hole 21 is defined in the center of the housing 20. The ends of the mounting opening 21 are connected to the rear cover 12 and the flange ring 13, respectively. Specifically, the mounting opening 21 is cylindrical, with its centerline collinear with the centerline of the housing 20. Two transition openings 22 are formed on each side wall of the housing 20. The two transition openings 22 on the same side wall of the housing 20 are located on either side of the mounting opening 21 and communicate with the corresponding mounting opening 21. The filler plates 30 are welded into the corresponding transition openings 22. The filler plates 30 seal the transition openings 22. During production, the housing 20 is constructed from a rectangular steel tube. A notch is cut along the length of the central and two side walls of the housing 20. A dedicated mold is then used to support the housing 20 from the notch outward, forming a mounting opening 21. Transition openings 22 are formed at either end of the notch. Filler plates 30 are placed within the transition openings 22. The flange ring 13 and rear cover 12 are installed at the two ends of the mounting opening 21, respectively. Finally, all joints are welded. The transition opening 22 is approximately triangular in shape.

[0033] In this embodiment, the shell 20 is formed by a whole rectangular steel tube. Compared with the existing bridge shell production, there is no need to prepare the upper shell 10 and the lower shell 11 separately, which is more convenient. In addition, because the shell 20 is formed by a whole rectangular steel tube, there is no need to weld additional rectangular steel tubes at both ends of the shell 20, the total length of the weld is reduced, and the welding workload is reduced.

[0034] In one embodiment, a plurality of through-holes 23 are formed on the side wall of the housing 20 near each filler plate 30; a connecting rod 40 is provided in each mounting hole 23; the connecting rod 40 can be retained in the mounting hole 23; a first stopper 41 is connected to one end of the connecting rod 40 located in the housing 20; the first stopper 41 abuts against the surface of the filler plate 30 facing the inner cavity of the housing 20. Specifically, four connecting rods 40 are arranged on the outer periphery of each filler plate 30, and two connecting rods 40 form a group, with the two groups of connecting rods 40 located on either side of the transition opening 22. Specifically, there are many ways to retain the connecting rod in the mounting hole 23. For example, the end of the connecting rod facing the inside of the housing 20 is smaller, while the end of the connecting rod located outside the housing 20 is larger. The smaller end of the connecting rod is inserted into the mounting hole 23 and then threadedly connected to the first stopper 41, while the larger end of the connecting rod is interference fit with the mounting hole 23.

[0035] In this embodiment, during production, after the mounting opening 21 and transition opening 22 are formed using a dedicated mold, the connecting rod 40 must first be placed and retained within the mounting hole 23. At this point, the first stopper 41 at the end of the connecting rod 40 is partially within the transition opening 22. The filler plate 30 can then be placed onto the first stopper 41 within the transition opening 22. The four stoppers support the filler plate 30, and welding is then performed to the gap between the outer periphery of the filler plate 30 and the transition opening 22. The four first stoppers 41 support the filler plate 30, ensuring that the filler plate 30 remains flush with the outer wall of the housing 20 during welding. Furthermore, the first stopper can be made thinner, forming a thin sheet to avoid interference with the interior of the housing 20.

[0036] In one embodiment, the integrally molded axle housing further includes a plurality of second blocks 42. These second blocks 42 abut against the outer wall of the housing 20 and are provided with adjustment holes 421. The mounting hole 23 has a rectangular cross-section, and the connecting rod 40 also has a rectangular cross-section. The connecting rod 40 slides along the centerline of the mounting hole 23. The connecting rod 40 is fixedly connected to the first block 41. A stud is connected to the end of the connecting rod 40 away from the first block 41, and the adjustment hole 421 is threadedly engaged with the corresponding stud.

[0037] In this embodiment, the connecting post is inserted into the housing 20 through the mounting opening 21. One end of the connecting stud on the connecting post passes through the mounting hole 23 and is positioned outside the housing 20. The connecting post is then threadedly connected to the stud using the adjustment hole 421 on the second stopper 42, thereby retaining the connecting post within the mounting hole 23. As the second stopper 42 rotates, the position of the first stopper 41 can be adjusted. This ensures that when the filler plate 30 is placed onto the first stopper 41 within the transition opening 22, the outer wall of the filler plate 30 remains flush with the outer wall of the housing 20, resulting in a better appearance. Furthermore, the connecting rod 40 slides into the mounting hole 23, allowing the end of the first stopper 41 to accurately extend into the transition opening 22 without requiring adjustment.

[0038] In one embodiment, a rubber stopper 43 is connected to the second stopper 42; after rotating, the rubber stopper 43 can abut against the outer wall of the filling plate 30. The rubber stopper 43 and the first stopper 41 respectively secure the filling plate 30 from two sides. The rubber stopper 43 has a certain degree of elasticity.

[0039] In this embodiment, the second stop block 42 rotates to adjust the position of the first stop block 41 so that the outer wall of the filling plate 30 placed on the first stop block 41 is flush with the outer wall of the shell 20. Then, the second stop block 42 is slightly rotated by a certain angle so that the rubber stop block 43 is against the outer wall of the filling plate 30, so that the first stop block 41 and the rubber stop block 43 fix the filling plate 30, thereby preventing the filling plate 30 from shaking during the welding process and affecting the welding quality.

[0040] In one embodiment, an abutting protrusion 431 is formed on a surface of the rubber stopper 43 at one end away from the second stopper 42 and facing the filling plate 30 . The abutting protrusion 431 can abut against the filling plate 30 .

[0041] In this embodiment, during the rotation of the second stopper 42, the filling plate 30 placed on the first stopper 41 moves outward. At this time, most of the rubber stopper 43 does not abut against the filling plate 30, thereby not increasing the friction force, so that the second stopper 42 can still rotate, and the abutting protrusion 431 on the rubber stopper 43 abuts against the filling plate 30. Subsequently, when the outer wall of the filling plate 30 is flush with the outer wall of the shell 20, the abutting protrusion 431 and the first stopper 41 fix the filling plate 30.

[0042] In one embodiment, a clearance groove 432 is defined on the side of the rubber stopper 43 facing the filler plate 30. This clearance groove 432 prevents the rubber stopper 43 from contacting the outer walls of the housing 20 and the filler plate 30 during rotation, further increasing frictional resistance. Furthermore, a rubber gasket may be positioned between the second stopper 42 and the housing 20 to seal the mounting hole 23.

However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
