Description

technical field [0001] The invention relates to a device for detecting and communicating tire temperature information in a rotating state, in particular to a tire temperature detecting device in a rotating state arranged at the center of the outer surface of a rim, belonging to the field of tire manufacturing. Background technique [0002] Tire temperature affects the safety, handling stability, comfort and energy-saving economy of automobiles. Detecting tire temperature and analyzing it can provide guidance for tire structure design, rubber formula design, and reduction of automobile energy consumption, which is of great importance. Practical significance. Therefore, many tire manufacturers are trying to detect and analyze tire vulcanization temperature and driving temperature, so as to provide guidance data for improving manufacturing process, optimizing process parameters, tire structure and rubber compound formulation. [0003] When the technical department of the tire ...

AI Technical Summary

Problems solved by technology

However, when the tire mileage test uses the above-mentioned method to measure the tire temperature, the rotation of the tire will cause the pair of electrodes of the thermocouple to break, so that the temperature detection task cannot be completed, and the tire temperature in the rotating state cannot be obtained.
