the motor 7 can rotate in the forward and reverse directions, when the tire needs to be braked, the motor 7 and the turbine driving device 5 rotate in opposite directions, and the power for stopping the operation of the turbine driving device 5 is started to achieve the braking purpose;
when the tire needs to be reversed and the automobile 9 carrying the tire needs to be reversed, the driving power can be provided by the motor 7 rotating in the reverse direction, and the compressor 53 can not perform effective centrifugal compression temporarily due to the reverse operation of the turbine driving device 5, so that the driving power for the backward operation is not provided any more in a short time.
