The invention provides a three-section type drive axle housing. The three-section type drive axle housing comprises an axle housing middle section and a set of integrated shaft heads. The integrated shaft heads are arranged at the two ends of the axle housing middle section, and the axle housing middle section and the integrated shaft heads are connected through flanges. A pin hole structure for mounting a brake, a structural part for mounting a bearing hub and a structural part for mounting a cam shaft are arranged on the integrated shaft head; the pin hole structure for mounting the brake, the structural member for mounting the bearing hub and the structural member for mounting the cam shaft are integrally formed with the integrated shaft head; the axle housing middle section and the connecting flange of the integrated shaft head are each provided with a cam shaft receding groove and a brake shoe pin dismounting groove. According to the integrated design of the integrated shaft head, the whole axle assembling efficiency is improved, and the product weight is saved; the axle housing middle section is in flange bolt connection with the integrated shaft heads at the two ends, the problem that the welding efficiency is low due to the fact that the welding seam section of the axle housing middle section and the shaft heads of the large-tonnage mine car axle is large is solved, production efficiency is improved, and product cost is reduced.
本发明提供了一种三段式驱动桥桥壳,包括桥壳中段和一组一体式轴头;一体式轴头设置在桥壳中段的两端,桥壳中段和一体式轴头之间通过法兰连接;一体式轴头上设置有安装制动器的销孔结构、安装轴承轮毂的结构件和安装凸轮轴的结构件;安装制动器的销孔结构、安装轴承轮毂的结构件和安装凸轮轴的结构件均与一体式轴头一体成型;桥壳中段和一体式轴头的连接法兰上均设置有凸轮轴避让槽和制动蹄销拆卸槽。本发明一体式轴头的集成设计提高了整桥装配效率,节约了产品重量;桥壳中段与两端一体式轴头为法兰螺栓连接,规避了大吨位矿车桥桥壳中段与轴头焊缝截面大导致的焊接效率低的问题,提高生产效率降低产品成本。
