汽车传感器里程表
Car sensor odometer
在差速器或者半轴上面的传感器，来感觉转动的圈数，一般用霍尔，光电两个方式来检测信号，其目的利用里程表记数可有效的分析判断汽车的行驶速度和里程，因为半轴和车轮的角速度相等，已知轮胎的半径，直接通过里程参数来计算。在传动轴上设计两个轴承，大大减轻了运行中的力距，减少了摩擦力，增强了使用寿命；由原来的动态检测信号改为齿轮运转式检测信号；由原来直插式垂直变速箱改为倒角式接口变速箱。里程表传感器插头一般是在变速箱上，有的打开发动机盖可以看到，有的要在地沟操作。
The sensor on the differential or axle shaft can sense the number of turns. Generally, hall and photoelectric methods are used to detect the signal. The purpose is to use the odometer to count, which can effectively analyze and judge the vehicle's driving speed and mileage. Because the angular velocity of the axle shaft and the wheel is equal, the radius of the tire is known, and the mileage parameter is directly used to calculate. Two bearings are designed on the transmission shaft, which greatly reduces the force distance in operation, reduces the friction force, and enhances the service life; the original dynamic detection signal is changed to the gear running detection signal; the original in-line vertical transmission is changed into the chamfered interface gearbox. The odometer sensor plug is generally on the gearbox, some can be seen by opening the engine cover, and some should be operated in the trench.
