The invention relates to a brake bottom plate integrated axle housing assembly which comprises an axle housing and a brake bottom plate, a machining outer circle is arranged on the axle housing. The machining outer circle is annular limiting protrusions located at the two ends of the axle housing, a machining inner hole is formed in the brake bottom plate, the machining inner hole is located in the center of the brake bottom plate and can be matched with the machining outer circle, the machining outer circle sleeves the machining inner hole, and the two sides of the brake bottom plate and theaxle housing are connected into a whole through a welding process. A bearing limiting boss and a bearing inner hole are arranged on the brake bottom plate, a bearing is arranged close to the bearing limiting boss, a cam shaft support is inserted into the bearing inner hole, a cam shaft is arranged on the cam shaft support, and the cam shaft is inserted into a hole in the middle of the bearing. A supporting pin hole is further formed in the brake bottom plate, and a supporting pin is inserted into the supporting pin hole; the brake bottom plate and the axle housing are directly welded, parts such as fixing flange plates and connecting bolts are omitted, the structure is optimized, weight reduction of the axle is facilitated, and cost is saved.

    本发明涉及一种制动底板一体式桥壳总成,包括桥壳和制动底板,所述桥壳上设置有加工外圆,加工外圆是位于桥壳两端的限位环状凸起,所述制动底板上设置有加工内孔,加工内孔位于制动底板的中心位置并且能够与加工外圆相互配合,加工内孔套入加工外圆,制动底板的两侧与桥壳通过焊接工艺连接成一体;制动底板上设置有轴承限位凸台和轴承内孔,紧靠轴承限位凸台设置有轴承,所述轴承内孔中插入凸轮轴支架,凸轮轴支架上设置有凸轮轴,凸轮轴插入轴承中间的孔;制动底板上还设置有支销孔,支销孔中插入支销;制动底板和桥壳直接焊接,节省固定法兰盘及连接螺栓等零部件,结构优化,有利于车桥降重以及节约成本。
