The invention discloses a drive axle of a 18-ton forklift wheel loader. An axle housing and a supporting shaft are welded to serve as a bearing part; wheel edge assemblies are supported on the two sides; a main speed reducer assembly is installed in the middle of the axle housing; the two sides of a half shaft are connected with the wheel edge assemblies and the main speed reducer assembly; an inner bearing 32028 and an outer bearing 32224 are respectively arranged in inner holes of a wheel shell so as to enhance the bearing capacity; the wheel shell is supported on the supporting shaft through the two bearings; an axle housing lug with an axle housing lug reinforcing rib is arranged on the axle housing; the wall thickness of the axle housing lug reinforcing rib is 20 mm; the axle housinglug reinforcing rib extends to the edge of the matching surface of a frame and the lug so as to meet the requirement of a heavy-load working condition; and during gear shaping of an inner gear ring, reverse modification is conducted during machining according to collected heat treatment deformation trend data, and it is ensured that the gear part is corrected after heat treatment so as to improvethe precision. The drive axle solves the problems that in the prior art, the bearing capacity of a wheel edge supporting shaft is insufficient, axle housing lugs are prone to breakage under the heavyload working condition, and the cracking failure rate of the inner gear ring is high.

    本发明公开了一种18吨叉装机驱动桥,以桥壳和支撑轴焊接后作为承载部件,两边支撑轮边总成,桥壳中间安装主减速器总成,半轴两边连接轮边总成和主减速器总成;轮壳的内孔分别安装32028内轴承和32224外轴承,以增强承载能力,并通过该两个轴承支撑在支撑轴上;桥壳上设有带桥壳耳座加强筋的桥壳耳座,该桥壳耳座加强筋壁厚采用20mm,并将该桥壳耳座加强筋延伸至车架与耳座的配合面边缘,以满足重载工况要求;内齿圈在插齿时根据收集的热处理变形趋势数据,加工时进行反向修形,确保热处理后齿部得到校正以提高精度。本发明解决了现有技术中轮边支撑轴承载能力不足、重载工况时易造成桥壳耳座断裂和内齿圈开裂故障率高的问题。
