Abstract

Automobile tyre lateral runout is one of the important indexes to measure the quality of the tyre, it will affect the safety of the automobile in moving. This paper introduces a sensor for automobile tyre lateral runout measurement. The variation of the automobile tyre lateral runout causes the change of guide rod probe displacement and deforms of the cantilever beam which connects with the guide bar. The deformation of the cantilever beam leads to the change of the resistance value of strain gauge which is pasted on the cantilever beam. Through measuring circuit, the resistance value of the strain gauge is converted into output voltage that has a certain relationship with automobile tyre lateral runout. Then, the voltage signal is transformed by A/D convertor and send to SCM to process and display the value of runout. Meanwhile, SCM output control signal to control the actuator and adjust the equipment running status in real time so as to ensure the tyre lateral runout is within the allowed range.
