Description
Technical Field
The invention belongs to the technical field of tires, and particularly relates to a non-pneumatic tire, in particular to a non-pneumatic tire with an elliptical total bearing structure.
Background
The current tire types are classified into pneumatic tires and non-pneumatic tires. Pneumatic tires are currently in wide use because of their "four low" advantage, low energy loss on the road, low vertical stiffness, low contact pressure and low mass. The pneumatic tire supports the crown part by sealing compressed air with rubber, and the problem of insufficient tire pressure, breakage and leakage or tire burst can occur in use, so that the vehicle can not run.
The non-pneumatic tire uses solid filler instead of compressed air, so that the above problems can be avoided and the maintenance-free and explosion-proof advantages are also achieved. However, a general non-pneumatic tire is poor in cushion property, is liable to jolt when running on a bad road surface, and is large in longitudinal deformation during running, so that a large running resistance is generated, and both comfort and economy are deteriorated. There is therefore a need for improvements to existing non-pneumatic tires to address the above-described problems.
Through analyzing the stress condition of the egg, the thickness of the eggshell is thin, but the eggshell can bear a larger force, because the arch structure of the eggshell effectively avoids the phenomenon of stress concentration. Zhao Zhouqiao the arched bridge deck has the characteristic of stress uniformity when being stressed, so as to prevent the bridge structure from being damaged due to overlarge stress at one point. The stress-dispersing property can be applied to the design of non-pneumatic tires, and the elliptical structure is applied to the design of the non-pneumatic tires, so that the non-pneumatic tires are correspondingly improved.
Disclosure of Invention
Through understanding the problems, the invention designs the non-pneumatic tire with the elliptical general bearing body structure, which can better solve the problems.
The non-pneumatic tire with the elliptical total bearing structure is divided into a crown part, an elliptical total bearing body and a rim combination ring sequentially from outside to inside along the radial direction.
The tire crown part sequentially comprises a tread with patterns, tread rubber, a buffer layer and a carcass ply from the near-ground side inwards along the radial direction of the tire; the tread band bonds the tread and the structure below the tread together.
The elliptical assembly bearing body is sequentially divided into an upper layer structure, a middle layer structure and a lower layer structure along the radial direction of the tire, each layer of structure is identical, the sizes of the layers are in a certain proportion, and each layer of structure is distributed according to one of units in an annular array mode.
Each layer of elliptical structure of the elliptical assembly body is divided into a longitudinal distribution mode of a long axis of the elliptical assembly body along the radial direction of the tire and a transverse distribution mode of a long axis of the elliptical assembly body perpendicular to the radial direction of the tire: the transverse elliptical minor axis is distributed along the radial direction of the tire, and its long axis is perpendicular to the tire radial direction; the longitudinal ellipse is positioned inside the transverse ellipse, and the length of the long axis of the longitudinal ellipse is equal to the length of the short axis of the transverse ellipse and the length of the short axis of the transverse ellipse are coincident.
The upper layer structure, the middle layer structure and the lower layer structure of the elliptical assembly body have the following proportional relationship: the proportion of the size of the lower layer structure is smaller than 1/2 of the structural size of the elliptical total bearing body, and the proportion of the size of the upper layer structure is smaller than 1/4 of the structural size of the elliptical total bearing body.
The angle value occupied by each unit structure of each layer in the elliptical assembly bearing body structure in the annular array distribution of the layer is 20 degrees.
The elliptic bearing body is made of polyurethane materials through casting, a space structure formed by the elliptic bearing body has good elasticity, a transverse elliptic structure and a longitudinal elliptic structure in the structure deform when the elliptic structure is subjected to external force, and reaction forces in the transverse direction and the longitudinal direction are generated, so that the tire can be dispersed and offset by the reaction forces generated by deformation no matter the tire is subjected to radial impact force or tangential driving force or braking force; therefore, the impact can be relaxed, the smoothness of the vehicle is improved, the tires cannot be deformed greatly due to stress, and the running resistance can be controlled well.
The elliptical assembly body is combined with the crown part and the rim combining ring through the outside of the film pressing vulcanization process.
The rim coupling ring is located between the elliptical assembly body and the rim, and the structure secures the tire to the rim.
The invention has the beneficial effects that:
(1) The invention relates to a non-pneumatic tire with an elliptical assembly bearing body structure, which does not adopt compressed air force as a tire support, and effectively avoids the problems of tire burst, air leakage and insufficient tire pressure in the pneumatic tire.

(3) The elliptical assembly bearing body is made of polyurethane materials, and the materials can be recycled, so that the elliptical assembly bearing body is environment-friendly.
(4) The invention relates to a non-pneumatic tire with an elliptical assembly bearing structure, which is formed by processing all structures together through a film pressing vulcanization process and has the advantage of strong integration.
