Abstract

The utility model provides an inflation-free tire which comprises a tire crown, a tire body and a tire toe which are integrally formed, wherein three annular buffer cavities are arranged in the tire body, a first buffer cavity is positioned at one side close to the tire crown, a second buffer cavity and a third buffer cavity are symmetrically distributed below the first buffer cavity, and Y-shaped supporting ribs are formed among the three buffer cavities. The utility model has the technical effects. The tire body is provided with three buffer cavities with special shapes and arrangement modes, and Y-shaped supporting ribs are formed among the three buffer cavities to form a supporting system with constant mechanical relation, so that the tire has reliable elasticity, and the tire can meet the load requirement and has good shock resistance on the basis of saving materials.

Description

Non-pneumatic tire

Technical Field

The utility model belongs to the field of tires, and particularly relates to a perforated non-pneumatic tire for a scooter or other small-sized scooter.

Background

The pneumatic tire is air with pressure sealed by rubber, when the air is compressed, the collision of air molecules to the wall of a container is more violent, so that the air pressure is increased, macroscopic elasticity is formed, and the pneumatic tire has good buffering performance, so that the pneumatic tire is very wide in application and is the first choice of the traditional automobile tire, bicycle tire and other vehicle tires. However, the pneumatic tire is easy to leak air and puncture, and the inflation, tire replacement and tire repair are frequently needed, which brings inconvenience to the production and life of people. Particularly, when the vehicle runs at a high speed, serious traffic safety accidents such as vehicle rollover and the like can be caused by sudden tire burst. The inflation-free tire omits an inflation inner tube, does not use air, and only utilizes the material and the structure of the tire to realize the support and the buffer performance, so that the solid tire is suitable for some large-scale load-carrying machines, but the shock resistance is poor, and the non-inflation tire cannot be suitable for light travel tools. The existing scooter, balance car and other small tools for riding instead of walk mostly adopt non-pneumatic tires with cavities inside, thereby reducing the weight of the tires and increasing the shock resistance. The existing inflation-free tire cavity is unreasonable in arrangement, and the weight can not be further reduced on the premise of ensuring the supporting force.

SUMMERY OF THE UTILITY MODEL

The utility model provides a three-hole inflation-free tire which is provided with a Y-shaped supporting structure, is stable in supporting and saves materials, and aims to solve the technical problem that the cavity of the existing inflation-free tire is unreasonable in arrangement.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the utility model provides an exempt from pneumatic tire, includes integrated into one piece's child hat, matrix and child toe, be provided with three annular cushion chamber in the matrix, first cushion chamber is located the one side that is close to the child hat, and second cushion chamber and third cushion chamber symmetric distribution form Y shape support rib in first cushion chamber below between the three cushion chamber.

Preferably, the upper width of the first buffer cavity is larger than the lower width.

Preferably, the top of the first buffer cavity is arc-shaped.

Preferably, the second cushion chamber and the third cushion chamber each include a first curve and a second curve, and the first curve is disposed along an outer wall of the carcass.

Preferably, the cross-sectional area of the three cushion chambers accounts for 40% -60% of the cross-sectional area of the tire.

Preferably, the crown top wall is provided with anti-skid grooves.

Compared with the prior art, the utility model has the advantages and positive effects that:

the tire body is provided with three buffer cavities with special shapes and arrangement modes, and Y-shaped supporting ribs are formed among the three buffer cavities to form a supporting system with constant mechanical relation, so that the tire has reliable elasticity, and the tire can meet the load requirement and has good shock resistance on the basis of saving materials.

FIG. 2 is a cross-sectional view of the non-pneumatic tire of the present invention;

in the above figures: 1. a crown; 11. an anti-slip groove; 2. a carcass; 21. a first buffer chamber; 22. a second buffer chamber; 23. a third buffer chamber; 24. a first curve; 25. a second curve; 26. a Y-shaped support rib; 3. the fetal toe.

Detailed Description

For a better understanding of the present invention, reference is made to the following detailed description taken in conjunction with the accompanying drawings and examples.

Example (b): as shown in fig. 1 and fig. 2, the non-pneumatic tire comprises a crown 1, a tire body 2 and a bead toe 3 which are integrally formed, wherein anti-skid grooves 11 are arranged on the tread of the crown 1, so that the tire obtains good anti-skid performance.

The tyre is characterized in that three annular buffer cavities are arranged in the tyre body 2, the first buffer cavity 21 is positioned at a position close to the tyre crown 1, the width of the upper part of the first buffer cavity 21 is larger than that of the lower part, the top of the first buffer cavity is in a circular arc shape consistent with the radian of the tyre surface, the lower part of the first buffer cavity is gradually reduced, and the whole tyre is in a smooth T shape. Second cushion chamber 22 and third cushion chamber 23 are located first cushion chamber 21 below, and bilateral symmetry distributes, second cushion chamber 22 and third cushion chamber 23 all include first curve 24 and second curve 25, and first curve 24 sets up along the outer wall of matrix 2. The cross-sectional area of the three buffer cavities accounts for 40-60% of the cross section of the tire. The three cushion chambers form a Y-shaped support rib 26 therebetween, forming a support system having a constant mechanical relationship that enables the tire to have reliable elasticity. The three buffer cavities are arranged in triangular stable positions, the elasticity of the tire is increased on the basis of stable support, and on the basis of reducing materials, the load requirement is met, and the shock resistance and the buffer performance are good. The inflation-free tire reduces the weight of the tire while saving materials, and further meets the requirement of portability of small travel tools such as scooters and balance cars.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention in other forms, and any person skilled in the art may apply the above modifications or changes to the equivalent embodiments with equivalent changes, without departing from the technical spirit of the present invention, and any simple modification, equivalent change and change made to the above embodiments according to the technical spirit of the present invention still belong to the protection scope of the technical spirit of the present invention.
