    汽车轮毂单元是连接汽车悬挂机构和车轮的传动部分!
     
    轿车的轮毂轴承过去最多的是成对使用单列圆锥滚子或球轴承。随着技术的发展,轿车已经广泛的使用轿车轮毂单元。轮毂轴承单元的使用范围和使用量日益增长,目前已经广泛发展使用到了第三代。
     
    第一代是由双列角接触轴承组成。
     
    第二代是外圈带法兰盘的双列角接触轴承单元,可简朴的将轴承套到轮轴上用螺母固定。使得汽车的维修变得轻易。车轮毂及刹车盘直接安装在法兰盘上。
     
    第三代轮毂轴承单元是采用了轴承单元和防抱刹系统相配合的一种结构。轮毂单元设计成有内法兰和外法兰,内法兰用螺栓固定在驱动轴上,外法兰将整个装置安装于车身。
     
    轮毂单元逐步取代轮毂轴承的主要有点:装车时无需调游隙,组装工艺更趋合理,轻小型化,可靠性高,维修方便,整体成本降低等。
     
    本公司主要开发第二、三代轮毂轴承单元,已经开发600多个型号。

     

     
    Development of hub units on automobiles
     
    Automobile hub units is the transmission part connecting the suspension system and the wheels.
     
    The most popular hub bearing used on a Vehicle used to be single row taper roller or ball bearing which are used in pairs. As technology develops, the passenger automobiles have been using sedan hub units. The range and volume of usage have been increasing rapidly. Now it has been generally developed to the third generation. 
     
    The first generation is made of dual row angle contact bearings. 
     
    The second generation is dual row angle contact bearing units with outer flange. The bearing can be simply attached to the wheel axle and fixed with bolts. This made the repairing of cars much easier. The hub of a vehicle and brake pad can be installed on the flange. 
     
    The third generation hub bearing units apply the structure combined by bearing unit and ABS system. Hub unit is designed into inner flange and outer flange, the inner flange is fixed to the drive axle with bolts, while the outer flange connects this whole device to the car. 
     
    The advantages of hub units taking the place of hub bearings are, no need to adjust the  Clearance when being installed, the assembling mechanics  gets more reasonable, it gets lighter while the reliability goes higher, convenient to maintain, the overall cost goes down, etc.
