摘　　要：国内现有EPS系统多采用转矩、转角传感器分别安装的办法解决两类信号的获取,造成成本的上升和精度不足。文中设计了转矩转角一体化传感器,选择了齿轮的材料及加工方法,并设计了齿轮侧隙消除机构,消除了齿轮换向时的回差。该传感器实现了集转矩测量、绝对转角测量以及转动方向判定于一体。The present domestic EPS system adopts the method of installing the torque and the angular sensor respectively to acquire two types of signals, which results in rising costs and a lack of precision. This paper designed a torque and angle integration sensor, which used the gear materials and its processing methods with the gear backlash elimination mechanism, eliminated the re- turn difference when the gear reversed. The sensor integrates the torque measurement, the absolute angle measurement and the judg- ment of the direction of rotation.
