A method of improving vehicle operation stability using the wheel of any one of claims 1-8, characterized by: when the wheel (2) is in a static or low-speed stage, the counterweight assembly (1) is positioned at a position of the slideway (31) close to the center of the wheel (2) due to the force of the torsion spring assembly (4) on the connecting rod (6), and the moment of inertia of the wheel (2) is small; when the rotating speed of the wheel (2) is gradually increased to a threshold value, the counterweight assembly (1) is far away from the center of the wheel (2) along the slideway (31) by virtue of the centrifugal force of the counterweight assembly, the moment of inertia is increased, and the angular momentum is increased; so that the vehicle has smaller moment of inertia when starting to a low-speed stage and has larger moment of inertia when starting to a high-speed stage; when the wheel (2) decelerates, the balance weight component (1) is reset from the position far away from the center of the wheel (2) to the position close to the center of the wheel (2) by means of the torsion force of the torsion spring component (4), and the whole moving process is automatically carried out.
10. The method for improving the running stability of a vehicle according to claim 9, wherein: the torsion of the torsion spring assembly (4) and the pressure of the stop balls (5) are adjusted to adapt to the wheels (2) of different speed stages.
11. The method for improving the running stability of a vehicle according to claim 9, wherein: the length of the connecting rod (6) and the configuration of the slideway (31) are adjusted to be suitable for wheels (2) with different outer diameters.
12. The method for improving the running stability of a vehicle according to claim 9, wherein: by adjusting the mass of the counterweight assembly (1) to change the increase in angular momentum of the wheel (2).
