Description

Elastic support tire

Technical Field

The utility model relates to an elastic support tire that uses on the wheel of rickshaw, bicycle, electric motor car, motorcycle and car belongs to automobile-used tire technical field.

Background

Tires are ground-rolling annular elastic rubber products mounted on various vehicles, and are usually mounted on metal rims (commonly called rims) for supporting the vehicle body, buffering external impacts, achieving contact with the road surface and ensuring the driving performance of the vehicle. The conventional tire comprises an inner tube and an outer tube, and the inflation of the inner tube mainly plays a role in shock absorption; the outer tire mainly protects the inner tire to prevent the inner tire from being worn or punctured by hard objects. The pneumatic tire has the characteristics of good damping effect, portability, flexibility and the like, and is widely applied to various vehicles. However, the inflatable tires have the hidden troubles of tire puncture, tire burst and the like, so that the safe running of the vehicle is influenced, and even the passengers and drivers of the vehicle can be injured. In order to avoid the phenomenon of tire burst, some vehicles adopt solid tires, namely, the tires are injection molded by adopting solid rubber or plastic, polyurethane and other materials, although the tires can eliminate potential safety hazards such as tire puncture and tire burst, the tires have poor damping effect and large resistance, and the riding comfort of the vehicles is greatly reduced. In addition, the solid tire has disadvantages such as easy internal heat generation and incapability of adjusting the internal pressure of the tire, and thus has a narrow application range. In order to solve the above problems, there have been designed elastically supporting tires, and fig. 1 and 2 show two typical elastically supporting tires, which are mainly composed of a tire bead and a plurality of elastic supporting bodies, the plurality of elastic supporting bodies are uniformly arranged around the axis of the tire bead, one end of each elastic supporting body is fixedly connected with the inner side of the tire bead, and the other end of each elastic supporting body is pressed against the rim of the wheel. Although the tire solves the problems of tire puncture, tire burst, shock absorption and heating, cavities (some tires are embedded with auxiliary shock absorption blocks with smaller elastic modulus) exist between adjacent elastic support bodies, the supporting force of the tire is uneven in the circumferential direction of the tire ring, the deformation of the tire ring in the circumferential direction can also be periodically changed in the traveling process of the wheel, the position deformation of the elastic support bodies is smaller, the position deformation of the non-elastic support bodies is larger, the wheel jolts, and the riding comfort of the vehicle is reduced. Particularly, when the wheel rolls obliquely (such as when the bicycle turns) or encounters an uneven road surface, and the side part of the tire bears a main load, the bumping phenomenon is particularly obvious, and the tire can not firmly grip the ground, so that the direction of the vehicle is unstable, and the driving safety of the vehicle cannot be ensured.
