Abstract
The invention discloses a bionic tire structure. The bonding mechanism of the vertebra and tenon of a snake is integrated and grafted into the end part of a belt ply of a tire, so that each belt ply forms a certain bevel angle and an interlamination difference along the horizontal and axial direction, the stress concentration on the should of the tire is improved and the stress between the belt ply and the tread rubber material is uniformly distributed. According to the belt ply structure of the tire, on the basis that an existing tire structure is only slightly modified, the bonding strength between belt ply and the tread rubber is enhanced; the occurrence that the edge part of the belt ply is likely to be displaced and deform during vulcanization later is reduced; the occurrences that the shoulder of the tire is cracked and the tire comes into burst due to overheat are reduced; the quality of the tire is greatly improved and the service life of the tire is greatly prolonged; The invention is also suitable for the design of the reverse wrapping end part of the tire; by arranging the bionic tire structure at the end parts of a reinforced layer and a carcass, the stress concentration at the bead of the tire can be remarkably reduced.
Description
Technical field
The present invention relates to Design of Tire Structure, be specifically related to a kind of bionics tire structure.
Background technology
Tire in the fabrication process, each layer belt ends is the main region that stress is concentrated with turning over bag end, empty the splitting with circle of the shoulder of tire is the broad form that tire destroys, substantially be that the stress of belt ends and anti-package end is concentrated and caused, therefore to fall when stress concentration is Design of Tire Structure must faced by problem.
Chinese patent CN102114754 by being mixed into the endurance quality that Fanglun slurry cake improves tire in bracing ply sizing material, but this mode is due to needs adjustment tyre stock, and the higher implementation of cost is loaded down with trivial details; Chinese patent CN102922951 reduces bracing ply edge deposit gas phenomenon to improve the life-span of tire by arranging doubling block between bracing ply interlayer, but this kind of mode needs design specialized forming machine, manufactures and designs complexity; Chinese patent CN203818934 is by carrying out bracing ply reinforcement to reach by tire shoulder winding steel wire the object improving tyre performance, but this kind of method can cause tire quality to increase, so that increases the rolling resistance of tire; Chinese patent CN1775568A by the marginal portion that increases edge strips and reinforcement material in belt ends and reduce by a bracing ply place from, but this patent structure is complicated shaping loaded down with trivial details and consider very few for No. two bracing plys that tire strain energy density is maximum, is difficult to be used in engineering practice.Therefore, still there is no a kind of amendment by a small margin under existing tire manufacturing equipment condition at present, do not increase tire production price and do not reduce tire production efficiency, and increasing the effective way of tire life.
Summary of the invention
Biologist finds through long-term observation, and the many biologies of occurring in nature, through the evolutionary development of millions of years, define special body structure.For snake class animal, when snake class moves on land, the earth's surface (such as hard rock) that can produce resistance to it must be found on ground, because it just conveniently utilizes the scale and shell of belly and ground to make actv. friction like this, utilize the convergent-divergent of gastrostege and muscle to produce displacing force, use before a health pushes away rapidly.And in snake class advance process, larger stress between its musculature and vertebrae, can be produced, be easy to cause visceral injury.Therefore snake class has been evolved out has overshooting shape to stab the vertebrae (as shown in Figure 2) of structure diagonally, adds the area of contact between snake class skeleton and muscle muscle tendon, makes the power being transmitted to snake vertebrae from ground can be dispersed.Motor tire is similar to snake class, all by utilizing the antagonistic force on ground to advance forward, bracing ply in tire is similar to the vertebrae of snake class, the effect of reinforcing and sharing stress is played to tire entirety, its strain energy density be subject to is larger, and the strain energy density gradient at bracing ply place and automobile tire life have remarkable relation, snake class morphosis is therefore utilized to carry out bionically having certain foundation.
By amendment bracing ply, the structure of body piles and enhancement Layer end, imitative snake class vertebrae sizing material structure is arranged in film end, make film end present wedge shape with other sizing materials to be connected, wedge length depends on the thickness of tyre film, when film stock thickness is 3mm, wedge length is 3mm to 5mm, wedge angle controls be less than or equal to 45 °, be more than or equal within the scope of 30 °, adopt multiple bracing plys of biomimetic features should towards unanimously, the enhancement Layer at tyre bead place and body piles end be towards also should be consistent simultaneously.
Based on the combination between snake class vertebrae and muscle tendon, use bionics method, the end of tire belt, enhancement Layer and body piles is adopted ramp structure, make the junction of the tyre film containing steel cord and other sizing materials form certain inclined-plane, increase the binding force between film and other sizing materials.The invention provides a kind of biomimetic features tire, comprise number one bracing ply, No. second bracing ply, No. three bracing ply, No. zero bracing ply, enhancement Layer and body piles; Described No. zero bracing ply comprises left No. zero bracing ply and right No. zero bracing ply, and described left No. zero bracing ply and right No. zero bracing ply are symmetrically arranged in the left and right sides of No. three bracing ply; Described number one bracing ply, No. second bracing ply imitate snake class vertebrae structure, described number one bracing ply, No. second bracing ply, two ends, left and right be wedge structure, the left side of described left No. zero bracing ply is wedge structure, and the right side of described right No. zero bracing ply is wedge structure; The upper end of described enhancement Layer, body piles is wedge structure.
In such scheme, the bevel direction of the left side wedge structure of the left side of described number one bracing ply, the left side of No. second bracing ply, left No. zero bracing ply is consistent, the mis-cut angle of left side wedge structure is 30 ° ~ 45 °, and the wedge length of left side wedge structure is 3mm ~ 5mm.
