In summary, the wheel assembly of the present application has the following advantages:

(1) The inner support body 2 endurance device is designed in the wheel system, so that the running capability and running stability of the whole vehicle in a tire burst or air-out state are ensured, the whole vehicle can still continue to run for a certain distance in the tire burst or air-out state, and the personal safety of passengers is ensured.

(2) Because the inner supporting body 1 is added, the weight of the wheel system can be obviously improved, so that the wheel system adopts a forged wheel design, the rim strength is higher, and the whole vehicle can be supported to run for a longer distance.

(3) Aiming at the puncture of the general small damage, the self-repairing tire scheme is adopted, so that the hole can be automatically repaired when the tire is punctured by a foreign matter within 5mm, the intervention of the endurance device of the inner support body 1 is not needed, and the running safety of the whole vehicle is ensured.

(4) Because the inner supporting body 1 continuation of the journey device is added in the wheel system, the fluid in the tire is disordered and cavity noise is easy to appear, the invention adds the mute sponge design on the tire sealant (namely the self-repairing layer), which can effectively reduce the cavity noise, reduce the noise at the ears of passengers and improve the comfort of the whole vehicle.

According to the development requirements of the heavy-load three-compartment vehicle/SUV/MPV platform: (1) When the whole vehicle is in a tire burst or air-out state, a driver can control the vehicle, and sharp shaking and deviation of the vehicle are reduced, so that the safety of passengers is ensured. (2) Because the wheel load of a heavy-duty vehicle is larger, in order to ensure that the whole vehicle runs for a certain distance at a certain speed, the wheels and the inner support body 1 are made of forged aluminum alloy materials; (3) Because the section height of the tire is small, the inner support body is not easy to assemble, and a convex structure is invented on the basis of the traditional rim structure, so that the convenience in assembling the inner support body and fastening a connecting bolt is ensured; (4) The noise at the ears of the passengers reaches the requirement of the C-ECAP platinum plate, so the tire adopts a silent sponge scheme.
