In the 1960s, my country introduced 3-ton loader technology from abroad and began to develop and produce it. Due to its reliable quality, the 3-ton loader torque converter assembly has not made many changes in its structure and has been used to this day; but with the increasingly fierce competition in the domestic market, product structure optimization and cost reduction are becoming more and more important. The existing 3-ton loader torque converter requires an additional transition plate and connecting bolts when installing the steering oil pump. The disadvantage is that it increases the cost of raw materials while also increasing the assembly quality. Summary of the invention

[0003] The utility model aims to provide a 3-ton loader torque converter steering oil pump assembly structure which has a simple and compact structure, reliable quality, low manufacturing and maintenance costs, and high steering oil pump installation efficiency, thereby solving the problem in the prior art that a transition plate and bolts are required when installing a 3-ton loader torque converter steering oil pump, which affects assembly efficiency and cost.

[0004] To achieve the above purpose, the utility model 3-ton loader torque converter steering oil pump assembly structure includes a torque converter housing 1, a steering oil pump 5, and a torque converter power take-off shaft 6. A sealing paper gasket 2 is provided between the torque converter housing 1 and the steering oil pump 5; a steering oil pump mounting boss 1.1 and a steering oil pump positioning stop 1.2 that is positioned and matched with the positioning stop of the steering oil pump 5 are provided on the mounting end surface of the torque converter housing 1. The steering oil pump mounting boss 1.1 is olive-shaped, and a mounting threaded hole 1.3 is provided near each end of the olive; the spline shaft of the steering oil pump 5 is connected and matched with the internal spline of the torque converter power take-off shaft 6 supported on the torque converter housing 1, and the torque converter housing 1, the sealing paper gasket 2 and the steering oil pump 5 are locked by a locking bolt 3 and a spring washer 4 through the bolt hole of the steering oil pump 5 and the mounting threaded hole 1.3 on the torque converter housing 1, so that the steering oil pump 5 is assembled on the steering oil pump mounting boss 1.1.

[0005] The above-mentioned 3-ton loader torque converter steering oil pump assembly structure has the following technical features and beneficial effects by directly designing the steering oil pump installation structure on the 3-ton torque converter housing:

[0006] 1. Eliminate the original transition plate and connecting bolts, reducing installation costs;

[0007] 2. The structure is simple and reliable, the production and maintenance costs are low, the assembly is convenient, and the assembly efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS
