摘要
车轮摆差测量技术是测量技术中重要的一门学科。现代汽车工业对传动部件—车轮的摆动要求愈来愈高,车轮的摆差大小也是汽车平稳行驶的保证。
本设计将车轮侧向和径向的摆差作为一个整体来检测,把车毂边缘作为车轮在侧向和径向摆差测量的位置，利用光栅位移传感器来检测车轮侧向和径向的摆差。它包括三个部分：首先是车轮摆差试验机的传动机构，其次是被检测车轮的定位和夹紧机构，再则是车轮的检测机构（检测侧向和径向的摆差）。通过车轮摆差试验机，可以精确的检测车轮在径向和侧向摆差的程度和大小，从而验证所生产的产品是否符合实际的使用要求，是否能够达到用时最短和最低成本的检测。同时它可以用于各种轻型轿车、卡车等无内胎车轮在径向、侧向摆差进行精确的检测。本文详细的分析了车轮摆差试验机的结构设计和工作原理。

ABSTRACT
Run-out tolerance measurement of thewheel on thevolume of technologyand technologyis an important measurement of a subject.Transmission components of the modern automobile industrythe swingwheel rising ever higher,the size of thewheels is bad the car before traveling to ensure a smooth.
The design of thewheel before the lateral and radial deviation to detect as awhole,the edge of the car as thewheel hub in place of lateral and radial deviation of the position measurement using grating displacement sensor to detect and track lateralwheel the pendulum to the poor.
It includes three parts: first,poor testing machine before thewheels of the transmission mechanism,followed bydetection of the positioning and clamping thewheel body,is again testing organizationswheels(detection of lateral and radial deviation of the pendulum).Poor through the testing machine before thewheels can accuratelydetect thewheels of the radial and lateral deviation of the pendulum and the size of the production in order toverifywhether a product complieswith the actual use requirements,whetherwe can achievewhen the shortest and lowest cost of test.At the same time,it can be used in avarietyof light cars and trucks in the radial tubelesswheels,side-facing aspects of homodyne detection of the detection accuracy.In this paper,a detailed analysis of the difference testing machine before thewheels of the structure andworking principle.
