The main axle body structure comprises an axle body, a cavity formed in the middle of the axle body in a punching and extruding mode and axle pipes on the two sides of the cavity, a front cover and a rear cover are welded to the front end and the rear end of the cavity respectively, through holes and mounting holes are formed in the surface of the front cover, and the through holes are used as the circle centers of the mounting holes. The rear cover is arranged on the periphery of the through hole in an array mode, and the surface of the rear cover is in a protruding shape. The method has the beneficial effects that the traditional multi-section type axle welding process is simplified to the greatest extent, and the defect of poor bearing capacity at the splicing part is reduced. The axle body structure maximally has the integral forming structure principle, the bearing capacity is greatly improved, when a vehicle body bears impact force caused by running, bumpy road conditions and downward pressure, the higher impact resistance is achieved, and especially under the condition that the load is large, the joint of the axle body is prone to deformation, so that internal transmission assemblies are damaged, and the service life of the axle body is prolonged. Therefore, the problem that a traditional welding axle is short in service life is solved.

    本发明公开了一种车桥的主桥体结构,包括桥体,所述桥体的中部由冲挤压而成型为空腔,以及空腔两侧的桥管,所述空腔的前后端分别焊接有前盖与后盖,所述前盖的表面设置有通孔与安装孔,数组安装孔以通孔为圆心,分别阵列排布在通孔的周边,所述后盖的表面为凸起形。有益效果:最大简化传统多段式焊接车桥工艺,减少拼接处承载力差的缺点。本桥体结构最大化具备一体成型结构原理,大大增加了承载力的效果,进而在车身承载行驶时,路况颠簸时,向下的压力而带来的冲击力时,具有更大的抗冲击性,尤其是载重较大的情况下,桥体连接处易发生形变,而导致内部传动组件的损坏,甚至桥体断裂,从而解决了传统焊接车桥使用寿命短的问题。
