The invention discloses a brake disc and hub assembly for a disc drive axle and a positioning fitting method. The brake disc and hub assembly comprises a brake disc, a bearing, a hub and bolts, wherein the bearing is pressed into the hub in an interference manner, and the brake disc fits the hub and is fastened to the hub through the bolts; a wheel installation surface and a brake friction surfaceare arranged on the brake disc; and a fitting surface A and a fitting surface B are arranged between the brake disc and the hub. The brake disc can be independently disassembled, the hub and the bearing do not need to be disassembled, and the disassembly of the brake disc does not need specific tools. The positioning fitting method solves the problems that no systematic design method is availablefor the positioning fitting design of the brake disc for the drive axle, and the brake disc of the drive axle is difficult to replace.
本发明公开了一种用于盘式驱动桥的制动盘与轮毂总成及定位配合方法,总成包括制动盘、轴承、轮毂、螺栓;所述轴承过盈压入所述轮毂上,所述制动盘与轮毂配合并通过螺栓紧固;其中,所述制动盘上设有车轮安装面及制动摩擦面;所述制动盘与轮毂两者之间设置有配合面A和配合面B;制动盘可实现单独拆卸,无需拆卸轮毂及轴承,且制动盘的拆卸不需要特定工装;定位配合方法解决了用于驱动桥的制动盘定位配合设计无系统性的设计方法、驱动桥更换制动盘困难问题。
