摘　　要：针对汽车轮毂轴承单元的开发及性能试验需求,研制了汽车轮毂轴承单元力矩刚性试验机。介绍了试验机的主要技术参数及功能要求。试验机由机械主体、气动加载系统、电气测控系统组成,采用气动加载方式对轮毂单元进行加载,利用高精度位移传感器测量轮毂单元在加载过程中的变形量,由计算机计算得出轮毂轴承单元的力矩刚度值。In view of the development and performance test requirements of the automobile hub bearing unit, the torque rigidity tester is developed for automobile hub bearing unit. The main technical parameters and functional requirements of tester are introduced. The tester is composed of main mechanical unit, pneumatic load system and electrical measurement and control system, and the hub unit is pneumatically loaded. The high precision displacement sensor is used to measure the deformation of the hub unit during loading process, and the torque rigidity of hub bearing unit is calculated by computer.
