Background

A vehicle tire is a ground-rolling annular elastic rubber article mounted on various vehicles or machines. Generally mounted on a metal rim, and is capable of supporting a vehicle body, buffering external impact, achieving contact with a road surface and ensuring the driving performance of a vehicle. Tires are often used under complex and severe conditions, which are subjected to various deformations, loads, forces and high and low temperature effects during running, and therefore must have high load-bearing, traction and cushioning properties. At the same time, high wear resistance and flexibility resistance, as well as low rolling resistance and heat resistance are also required. The structure of the tires in all countries around the world is developed towards tubeless, flat (the ratio of the height to the width of the tire section is small) and light weight. Most of the current vehicle tires are bias tires and radial tires. The rubber used in tire production today accounts for half of the amount of rubber consumed worldwide, which is seen in the ability of tires to consume rubber. At present, the low-carbon work is vigorously developed in the vehicle tire industry by improving and transforming traditional chemical equipment, popularizing efficient energy-saving technology and devices and the like. By popularizing the low-carbon development, the whole industry is promoted to be upgraded, and tire products are transformed to the directions of high performance, green, safety and the like. High performance tires produce a large amount of carbon dioxide during production, but the emission of such gas during running is greatly reduced, and the importance and urgency of development of high performance wheels are seen.

Disclosure of Invention

The invention relates to a solid tyre made of tread rubber supported by a steel ring, and an elastic hinge structure consisting of a hinge and a spring is connected with a hub to form an integrated elastic hinge wheel.

The invention relates to the working principle of elastic hinge vehicle tyre

The solid tyre is made by supporting tread rubber by a steel ring, and then a plurality of spring hinge hinges which are distributed in a star shape according to the design requirement (the star distribution is to balance when the wheel rotates, the figure is designed according to 5) are fixedly installed with a wheel hub through a shaft pin to form an elastic hinge structure, the structure enables the wheel tyre to generate good bearing performance, traction performance and strong buffering elastic force, the spring hinge structure ensures that the solid tyre with the steel ring and the wheel hub do eccentric movement on the same plane when the solid tyre with the steel ring and the wheel hub do eccentric movement on the same plane under the matching of a spring, and the elastic hinge structure also ensures that the front wheel and the rear wheel do not generate lateral deviation when the vehicle turns left and right. Two annular soft rubber screws are clamped and fixed at two ends of each shaft pin of the spring hinge through the wheel edge clamping steel ring on two sides of the elastic hinge vehicle tire, namely the solid tire and the wheel hub, the two annular soft rubber screws on the two sides can play the roles of sealing, water proofing and dust proofing, the screws are fastened at two ends of each shaft pin of the spring hinge, the wheel edge clamping steel rings on the two sides and the wheel edge of the sealing, dust proofing and soft rubber are well installed and fixed, and the solid tire steel ring and the wheel hub are clamped and fixed together. The invention uses soft rubber as the sealing dustproof soft rubber wheel edge, because the soft rubber can ensure that the solid tyre can not generate large resistance when moving and pulling with the wheel hub when impacting on the road surface, thereby influencing the buffer performance of the elastic hinge wheel tyre.
