The invention relates to the technical field of hub bearings, in particular to a high-load lightweight hub bearing. Comprising a driving shaft, a hub bearing, a half shaft bolt, a first locking glue layer and a second locking glue layer. A first connecting shaft at the end of the driving shaft is provided with a first connecting hole; the hub bearing is provided with a second connecting hole, and the hub bearing is detachably connected to the first connecting shaft; the half shaft bolt comprises an end cover and a second connecting shaft detachably connected to the first connecting hole. The end cover abuts against the hub bearing and is used for keeping the driving shaft and the hub bearing relatively fixed; the first locking glue layer is arranged between the half shaft bolt and the driving shaft; and the second locking glue layer is positioned between the hub bearing and the driving shaft. The light-weight connecting structure of the driving shaft assembly and the hub bearing is light in weight, and oil consumption can be reduced; during maintenance, the suspension control arm does not need to be disassembled, the disassembly and assembly torque is small, and the maintenance efficiency is high; the structure is firm, the connection failure risk is avoided, and the vehicle starting abnormal sound is eliminated.

    本申请涉及轮毂轴承技术领域,特别涉及一种高载荷轻量化轮毂轴承。包括驱动轴、轮毂轴承、半轴螺栓、第一锁固胶层和第二锁固胶层。驱动轴端部的第一连接轴具有第一连接孔;轮毂轴承具有第二连接孔,轮毂轴承可拆卸连接于第一连接轴;半轴螺栓包括端盖和可拆卸连接于第一连接孔的第二连接轴;端盖抵接轮毂轴承,用于使驱动轴和轮毂轴承保持相对固定;第一锁固胶层设置于半轴螺栓和驱动轴之间;第二锁固胶层位于轮毂轴承和驱动轴之间。本发明的轻量化驱动轴总成与轮毂轴承连接结构的重量轻,可降低油耗;维修时不需拆解悬架控制臂,拆装力矩小,维修效率高;结构牢固,无连接失效风险,且消除了车辆起步异响。
