The invention relates to the technical field of automobile parts, discloses a suspension type mileage sensor, and solves the problems that a mechanical input interface is canceled and an original contact type speed sensor on a vehicle is replaced by an induction type speed sensor due to rapid development of an automobile technology in the current market, but a vehicle speed sensor cannot meet userequirements of a vehicle with a navigation function. The suspension type mileage sensor comprises a sensor shell, a signal processing circuit board, a grating coded disc, an electric connector, a rotating shaft, a mounting disc, an encoder and a driving angular contact type bearing. The rotating shaft is rotatably connected to the interior of the sensor shell, and the grating coded disc is connected with the signal processing circuit board. The encoder, the grating coded disc and the signal processing circuit board are fixedly installed in the sensor shell, the mounting disc is arranged at the bottom of the sensor shell, and the top of the mounting disc is fixedly connected with the bottom of the sensor shell. According to the invention, the sensor has anavigation vehicle mileage sensingfunction, and the problem that the suspension type mileage sensor is disengaged under the condition of high-speed rotation is avoided.
本发明涉及汽车零部件技术领域,且公开了一种悬挂式里程传感器,解决了目前市场上的汽车技术的迅猛发展,机械式输入接口已被取消,车辆上原有的接触式速度传感器已被感应式速度传感器取代,但是车用速度传感器不能满足具有导航功能车辆的使用要求的问题,其包括传感器外壳、信号处理电路板、光栅码盘、电连接器、转动轴、安装盘、编码器和带动角接触式轴承,传感器外壳的内部转动连接有转动轴,传感器外壳的内部固定安装有编码器、光栅码盘和信号处理电路板,传感器外壳的底部设有安装盘,安装盘的顶部与传感器外壳的底部固定连接,本发明,具有实现导航车辆里程传感,避免一种悬挂式里程传感器在高速旋转的情况下出现脱离的问题出现。
