TECHNICAL FIELD

[0001] The present invention belongs to the technical field of tires, and in particular to a non-pneumatic tire.BACKGROUND TECHNOLOGY

[0002] At present, tires are divided into pneumatic tires and non-pneumatic tires. Pneumatic tires are hermetically sealed by rubber and are supported by steel wires and cords, but when they are pricked by sharp objects, they will have the danger of puncture, which will make the vehicle unable to run normally. The birth of non-pneumatic tire successfully solved the problem that vehicles can't run due to puncture. The non-pneumatic tire use structure and materials to realize the function of bearing and cushioning. Compared with traditional pneumatic tires, non-pneumatic tires have characteristics such as flat free, puncture resistance, economy, and wear resistance. The invention patent with the publication number of CN1278880C discloses a non-pneumatic tire, which is used to solve the shortcoming of pneumatic tires being easy to leak and burst. The invention patent is characterized in that one or a plurality of groups of interconnected plate-like elastic supports (referred to as wheel blades for short) are mounted along the circumferential direction of the wheel to bear the load of the wheel. A device embodying the patent includes four components, the first is a rim as a mounting and bearing base, the second is one or a plurality of groups of wheel blades made of elastic materials, and the third is a wrapping piece or outer tire and liner that wraps the wheel blades to prevent them from being eroded by sand and other things, as well as bolts and nuts for assembling and pretensioning the device. The patented device features simple structure, reliable operation, stable operation and long service life, and is widely used in vehicles and machinery that require high safety, stationarity and reliability of tires. However, the above-mentioned patent has the following shortcomings: the plate-like elastic support used in the non-pneumatic tire is fixedly connected with the hub only by bolts and nuts, which easily causes the loosening of the plate-like elastic support because there is no good locking mechanism; secondly, the non-pneumatic tire do not have a good cushion mechanism, which makes it difficult to support and shock absorb the whole tire, resulting in poor durability of the tire. Therefore, improvement is needed. CN111301062A discloses a non-inflatable wheel based on a negative poisson ratio structure. The non-inflatable wheel comprises a hub, a negative poisson ratio supporting body and an outer tire surface, wherein the negative poisson ratio supporting body is installed on the outer side of the hub in a surrounding mode, an outer tread is installed on the outer side of the negative poisson ratio supporting body, in a surrounding mode, the hub is a flat-bottom rim, spokes and mounting holes are the same as those of a conventional hub, the negative poisson ratio supporting body has the elastic deformation capacity, the outer tread is made of low-rolling-resistance rubber, and the tread is provided with patterns for increasing friction force.CONTENT OF THE INVENTION
