[0037] In actual application, the tire high acceleration test injection temperature measuring device is arranged on one side of the loading head 02 of the test bench on which the tested tire 01 is installed. During the test of the tested tire 01, the temperature measuring drive device 3 drives the mounting frame 1 to move and approach the tested tire 01, thereby moving the injection mechanism 2 to the tested tire 01 to the position to be tested, and the injection drive mechanism 22 drives the temperature measuring needle 21 to move and penetrate the temperature measuring needle 21 from the surface of the tested tire 01 into its interior. The temperature measuring needle 21 collects the temperature at the tested tire 01 position to be tested, which is convenient for tire performance testing to meet the requirements of high acceleration tire testing.
