Non-pneumatic tire of elliptical overall bearing body structure

Abstract

The invention specifically relates to a non-pneumatic tire of an elliptical overall bearing body structure. The non-pneumatic tire comprises a tire crown part (1), an elliptical overall bearing body (2) and a rim joint ring (3); the tire crown part (1) sequentially comprises a tread (1-1), a tread compound (1-2), a buffer layer (1-3) and a carcass ply (1-4) from the near-ground side to the inside;the elliptical overall bearing body (2) is divided into an upper layer structure (2-1), a middle layer structure (2-2) and a lower layer structure (2-3) in the radial direction of the tire; each layer consists of a transverse elliptical structure and a longitudinal elliptical structure which is located in the transverse elliptical structure; and the major axis of each longitudinal elliptical structure coincides with the minor axis of the transverse elliptical structure correspondingly. According to the non-pneumatic tire of the elliptical overall bearing body structure, the elliptical overallbearing body (2) can fully absorb the impact force received by the tire crown part (1) and uniformly distribute the load, and the radial deformation generated by a stress point of the tire is reduced, so that the non-pneumatic tire has better buffering property and durability.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a non-pneumatic tire, in particular to a non-pneumatic tire with an elliptical overall bearing structure. Background technique [0002] The current tire types are divided into pneumatic tires and non-pneumatic tires. Pneumatic tires have the advantages of "four lows" - low energy loss on the road surface, low vertical stiffness, low contact pressure and low quality, so they are currently widely used. Pneumatic tires use rubber seals to compress the air to support the crown. During use, there may be insufficient tire pressure, damage, deflation or blowout, which will make the vehicle unable to drive. [0003] Non-pneumatic tires use solid fillers instead of compressed air, so the above problems can be avoided and they also have the advantages of maintenance-free, run-flat tires. However, general non-pneumatic tires have poor cushioning properties, are prone to bumps when driving o...

AI Technical Summary

Problems solved by technology

However, general non-pneumatic tires have poor cushioning performance, are prone to bumps when driving on bad roads, and have large longitudinal deformation during driving, which will generate greater driving resistance, resulting in a decrease in comfort and economy.
