Non-pneumatic tyre

Abstract

The invention discloses a non-pneumatic tyre. The non-pneumatic tyre comprises an annular inner ring part, an annular outer ring part and a supporting part, wherein the outer ring part is arranged on the periphery of the inner ring part in a sleeving manner, and the supporting part is arranged between the inner ring part and the outer ring part; the supporting part comprises a plurality of vaulted inner supporting components, outer supporting components and middle supporting components, wherein the vaulted inner supporting components are arranged on the periphery surface of the inner ring part, and the middle supporting components are positioned between the inner supporting components and the outer supporting components; the outer supporting components and the middle supporting components extend in the circumferential direction in a wavy manner, and the inner ring part is surrounded by the outer supporting components and the middle supporting components; the wave crest of each outer supporting component is connected with the inner periphery surface of the corresponding outer ring part, and the wave trough of each outer supporting component is connected with the wave crest of the corresponding adjacent middle supporting component; in two adjacent middle supporting components, the wave trough of each middle supporting component adjacent to the outer ring part is connected with the wave crest of the corresponding middle supporting component adjacent to the inner ring part; two ends of the inner supporting components are connected with the periphery surface of the inner ring part, and the top of each inner supporting component is connected with the wave trough of the corresponding adjacent middle supporting component. The non-pneumatic tyre disclosed by the invention is good in buffering effect and high in torsional rigidity.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a non-pneumatic tire. Background technique [0002] Pneumatic tires are filled with air with a certain pressure. In use, the deformation of the tire is mainly used to carry the load and buffer the impact. However, such inflated tires are likely to have the risk of air leakage, and if sudden air leakage such as punctures occurs in the pneumatic tires running at high speed, it is also easy to cause traffic accidents. [0003] Thus, in an existing air-free tire, its spoke plate extends radially along the tire, so that when the tire is in contact with the ground, the length direction of the main load-bearing spoke plate tends to be perpendicular to the road surface, so that the spoke plate The spoke plate can only carry or cushion the load by stretching or compressing in the radial direction of the tire, and transmit torque through the bending deformation of the spoke plate. For tire...

Problems solved by technology

However, such inflated tires are prone to the risk of air leakage, and sudden air leakage such as punctures in the high-speed running pneumatic tires may easily lead to traffic accidents.

[0003] Thus, in an existing air-free tire, its spoke plate extends radially along the tire, so that when the tire is in contact with the ground, the length direction of the main load-bearing spoke plate tends to be perpendicular to the road surface, so that the spoke plate The spoke plate can only carry or cushion the load by stretching or compressing in the radial direction of the tire, and transmit torque through the bending deformation of the spoke plate

For tires with this structure, since the deformation of the spoke plate along its length is limited in tension or compression, the buffering effect of the load is poor. Torsional rigidity, and then there is a certain hysteresis in the transmission of torque
