Embodiment Construction

[0017] see figure 1 , figure 2 and image 3 As shown, the present invention is composed of a flexible rim 1, an elastic spoke 2 and a rigid hub 3, the flexible rim 1 is fixed on the outside of the elastic spoke 2, and the rigid hub 3 is fixed on the inside of the elastic spoke 2;

[0018] The flexible rim 1 includes a steel ring 11, a polyurethane interlayer 12 and a rubber layer 13. The rubber layer 13 is fixed on the outside of the polyurethane interlayer 12, and the steel ring 11 is fixed on the inside of the polyurethane interlayer 12. The polyurethane interlayer 12 is nearly radially symmetrical to the center of the wheel. H-shaped structure, the upper and lower angles of the structure are 155° and 125° respectively, and the contact points connected to the steel ring 11 have an angle of 30° along the radial axis passing through the center of the wheel, and are evenly distributed on the steel ring at intervals of 40° above, forming a honeycomb-like hexagonal structure; ...

Abstract

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.

Description

technical field [0001] The invention relates to a wheel, in particular to an air-free off-road wheel. Background technique [0002] China is one of the countries with the most cars in the world. Tires are an important part of cars. The quality and performance of tires directly affect the safety and driving performance of cars. At present, rubber pneumatic tires are generally used for the wheels of road vehicles. With the my country's development and exploration of desert tidal flats, soft seabeds and starry sky surface has increased, as well as the research and development and upgrading of military vehicle mobile systems. The requirements for tires are also getting higher and higher. Most of the tires are rubber elastic tires, which are difficult to adapt to various conditions when walking. Complicated roads and poor load-carrying capacity. When driving on extremely complex non-road surfaces, it needs to be inflated and deflated regularly to improve its off-road maneuverabil...
