Off-road vehicle wheel free of inflation

The invention discloses an off-road vehicle wheel free of inflation. The off-road vehicle wheel free of inflation is composed of a flexible rim, elastic spokes and a rigid hub. The off-road vehicle wheel free of inflation is normally installed on an off-road vehicle. When the off-road vehicle runs, the off-road vehicle wheel free of inflation bears the action of a complicated road surface, and the flexible rim and the elastic spokes generate elastic deformation under the action of external force. When the external force is eliminated, the flexible rim and the elastic spokes recover. In this way, the external force is effectively buffered, shock of the vehicle is reduced, and the bearing capacity of the vehicle is improved. Through a polyurethane interlayer of a hexagonal structure similar to a honeycomb, the firmness of the wheel is improved, a load is evenly distributed, and therefore the environmental adaptability and the safety are improved. A rubber layer is provided with rubber wheel thorns, and therefore the traction performance and the adhesion performance of the vehicle are improved. The off-road vehicle wheel free of inflation is simple in structure, convenient to replace, high in applicability and suitable for various complicated road surfaces, air leakage and burst are avoided, the shock of the vehicle can be effectively reduced, the bearing capacity and the buffering capacity of a vehicle body are improved, the environment adaptability and the safety are improved, and the traction performance and the adhesion performance of the vehicle are improved.
