Bear the weight of the automobile, relieve the impact that the automobile received when going, guarantee the ride comfort, traction, braking nature and the trafficability characteristic of automobile. The good adhesion between the tire and the road surface is the basis of all the performances.
The off-road vehicle tire needs to deal with different road conditions and different climatic conditions, and the conventional off-road vehicle tire has high-speed maneuvering capability on a common road but has lower adhesive capability on a soft, muddy, ponding, wet and slippery and other low-adhesion road. Tires with high adhesion capacity lack high speed maneuverability, and the running requirements can be met only by replacing the tires when road conditions and weather conditions change.
Camels are called desert boats, and are the main riding tools in desert and semi-desert areas, especially desert areas, and have been widely used for desert exploration and other works. The camel has large, light and fast pace and strong endurance, and is suitable for being used as an important transportation means in desert due to the special structure of the hoof. When the humped camel rides in a short distance, the speed of the humped camel can reach 10-15 kilometers per hour, and when the humped camel rides in a long distance, the humped camel can travel 30-35 kilometers per day. Is inspired by the structural performance of the toe end of the camel, carries out pattern design and improves the passing capacity of the tire on soft ground.
The wood frog lives in the wet environment of tropical rain forest, the survival activity is mainly on the tree, and the wood frog can be attached to the surface of an object for a long time. The special sucker is grown on the toe tip of the foot end of the tree frog, can be adhered to a wet and slippery substrate in the crawling process, and has the characteristics of high adhesion and high friction force. Therefore, the design of the pattern of the water accumulation road surface tread is carried out by inspiring by the adhesion performance of the tree frog toe end, so as to improve the friction adhesion performance and the drainage performance of the tire and realize the stable running of the vehicle on the water accumulation road surface.
The bionics theory is a principle which is obtained from biological learning and has guiding significance to scientific technology. The camel toes and the tree frogs sole have good drainage and adhesion due to the structural characteristics, and the camel toes and the tree frogs sole are introduced into the all-region bionic wheel of the cross-country vehicle, so that the camel toes and the tree frogs sole have important significance for solving the all-region traffic problem of tires.
