Tread and belt ply combined type non-pneumatic tire

Abstract

The invention relates to a tread and belt ply combined type non-pneumatic tire, which comprises a rim, a tread component and a supporting body, wherein the supporting body is distributed on the outer peripheral wall surface of the rim in a surrounding manner and comprises a plurality of rows of blocky pieces each of which has a hollow structure made of plastics, intervals are kept between two adjacent rows of blocky pieces in the plurality of rows of blocky pieces, intervals are also kept between two adjacent blocky pieces in each row of blocky pieces, the tread is formed by combining and mould-pressing a rubber layer and two steel wire belt ply layers which are crossed with each other. The non-pneumatic tire has the characteristics of being low in manufacturing and maintenance cost, low in mass, capable of lightening the weight of vehicles, lowering the maintenance cost and achieving the energy-saving and environment-friendly purposes, long in service life, non-pneumatic, fearless of being punctured, and safe and reliable, and has the buffering and damping functions; similar with the tread part of a pneumatic tire, the compressive variation of the tread can be greatly decreased, the rigidity of the tread can be enhanced, the rolling resistance of the tire can be reduced, and the high-speed performance can be improved.

Description

technical field [0001] The invention relates to a non-pneumatic tire, in particular to a non-pneumatic tire with a tread combined with a belt layer. Background technique [0002] Tire is a circular elastic connection between the car and the road, it is the running mechanism of the car, and it is one of the important components of the car. It mainly bears the load of the car, ensures the grip between the wheels and the road surface, transmits the power of the car to the road surface, reduces and absorbs the vibration and impact of the car while driving, prevents the parts of the car from being subjected to severe vibration and early damage, and ensures the safety of the car driving sex and comfort. [0003] Tires are very important to cars, and their quality will play a key role in safe driving. Good tires can not only ensure your driving safety, but also save you fuel. [0004] According to the working principle of tires, they can be divided into two categories: solid tir...

Problems solved by technology

[0015] Although these air-free tires have the advantages of light weight, simple manufacturing process, no need to inflate, and no fear of punctures, it is difficult to achieve a balance between load bearing and shock absorption in terms of ride comfort, rolling resistance, and high-speed performance.

In addition, since the tread is made of pure rubber and there is no belt layer in the middle, the compression deformation of the tread is relatively large, and the rolling resistance and high-speed performance cannot reach the level of pneumatic tires.
