Referring to Fig. 6, when the inflatable piston 9921 is in this position, the tire pressure of the inflated tire 93 is not enough due to the gas flow passage in the sealed cavity 9922.

Then the traveling wheel is rotated forward, and the rotating speed of screw mandrel 994 is higher than the rotating speed of threaded sleeve 993 under the effect of differential mechanism 995, and threaded sleeve 993 also produces rightward translation relative to screw mandrel 994, and the structure of translation is to drive inflatable piston 9921 moves right and makes the gas in the sealed cavity 9922 be compressed in the air-filled tire 93, so that the running wheels are supported by the air-filled tire 93 to walk. When the inflatable piston 9921 moves to the right and abuts against the cylinder 991, the torque of the screw mandrel 994 will increase, making the force limiter 9942 slip, thereby automatically realizing the rotation. In the same way, when the pneumatic tire 99 is deflated to be supported by the roller 991, the running wheel can be reversed, and the result of the reverse is that the screw rod drives the inflation piston 9921 to move to the left, so that the gas in the pneumatic tire 93 flows into into the sealed chamber 9922, so that the pneumatic tire 93 can collapse and be supported by the roller 991.

When it is not necessary to inflate and deflate, the clutch gear 9953 is pulled out from between the first friction plate 99421 and the second friction plate 99422.
