The invention provides a micro-light truck hollow front axle with shock absorber holes and a manufacturing method thereof, and belongs to the technical field of automobile parts, and the micro-light truck hollow front axle comprises a hollow axle body, shock absorber rings, steering limiting blocks and fist end plugs. The hollow shaft body comprises a middle cross beam, bent necks and fists, the bent necks are arranged at the two ends of the middle cross beam, the fists are arranged at the ends of the bent necks, rectangular holes are formed in the fists, the rectangular holes are sealed and welded through the fist ends, main pin holes used for installing main pins are formed in the fists, and lock pin holes are formed in the main pin holes inwards in the axial direction. A limiting block groove is formed in the rear side of the fist head, and a steering limiting block is embedded and welded into the limiting block groove. A damper hole is formed in the end of the bent neck, blind holes are formed in the front side and the rear side of the end of the bent neck, and damper rings are welded to the front side and the rear side of each blind hole. The shock absorber holes are machined in the solid structure, the strength requirement for mounting the shock absorber pin shaft is met, and the situation that water enters the inner cavity of the hollow front shaft when the shock absorber pin shaft is assembled, and consequently the service life is shortened is avoided.

    本发明提供了一种带减震器孔的微轻型货车空心前轴及其制造方法,属于汽车零部件技术领域,包括空心轴体、减震器环、转向限位块、拳头端部封堵。空心轴体包括中部横梁、弯脖和拳头,中部横梁的两端均设置有弯脖,弯脖的端部设置有拳头,拳头内部设置有矩形孔,矩形孔通过拳头端部封堵焊实,拳头上设置有用于安装主销的主销孔,主销孔沿轴向向里设置有锁销孔,拳头的后侧设置有限位块凹槽,限位块凹槽内部嵌入并焊接有转向限位块。弯脖的端部设置有减震器孔,弯脖的端部前后两侧设置有盲孔,盲孔的前后两侧焊接有减震器环。本发明在实体结构上加工减震器孔,满足安装减震器销轴的强度要求,避免装配减震器销轴时空心前轴的内腔进水而降低使用寿命。
