In addition, the integral casting axle housing also has problems such as high machining difficulty and poor precision control in subsequent machining. Therefore, how to reduce the manufacturing cost of the axle housing and improve the production efficiency has become a technical problem to be solved in the field. SUMMARY

[0003] The utility model aims at providing a sectional engineering vehicle axle housing structure, which divides the axle housing into three parts, manufactures them respectively and then assembles them, so as to reduce the manufacturing cost and improve the production efficiency.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] A sectional engineering vehicle axle housing structure, comprising a bridge package and left and right axle shafts symmetrically arranged at the left and right ends of the bridge package, the left and right ends of the bridge package are open, and each is provided with an inwardly recessed connecting groove for matching connection with the connecting part of the left and right axle shafts.

[0006] Preferably, the connecting part is a stepped boss, the outer surface of the boss is attached to the inner surface of the connecting groove, and the stepped inner end surface of the boss is attached to the outer end surface of the bridge package.

[0007] Preferably, the end surface where the connecting part is attached to the bridge package is respectively provided with a second annular groove and a first annular groove, the second annular groove and the first annular groove form a welding interface to ensure that the bridge package tightly matches the left and right axle shafts when welded.

[0008] Compared with the prior art, the utility model has the beneficial effects that: by dividing the axle housing into three parts, the bridge package is made by casting process, and the axle shaft is made by turning process, which reduces the consumption of casting materials and the production cost; the axle shaft is made by turning process, which has high machining precision and efficiency, and avoids the complex process of integral casting, thereby shortening the production cycle; the sectional structure makes the maintenance and replacement of the axle housing more convenient, only the damaged part needs to be replaced, and the whole axle housing does not need to be replaced, thereby reducing the maintenance cost; the axle shaft made by turning process has high precision, and has good matching with the welding interface of the bridge package, so that the overall strength and stability of the axle housing after welding are higher.
