Provided is a deformable wheel. Spokes can extend or contract in the radial direction, and a cam in a hub controls a hydraulic loop of the spokes. When the spokes rotate to be close to the vertical line of the surface of a vehicle frame by a certain angle, the hydraulic loop of the spokes is closed by the cam, and the spokes can bear weights; when the spokes rotate away from the vertical line of the surface of the vehicle frame by a certain angle, the hydraulic loop of the spokes is opened by the cam. The shape of the wheel changes along with the change of the shape of pavement, and therefore the wheel can cross over various barriers. Due to the fact that the angle of the cam can be adjusted, the height of the axis can be adjusted, and a vehicle body can be kept stable on an inclined pavement or a curve. Due to the fact that the pressure of liquid in the hub can be adjusted, proper pre-pressure can be adjusted and applied to a flexible pavement, and a vehicle with the wheels can run quickly and accurately on various rugged pavements.
