Description

Inflation-free rubber tire

Technical Field

The utility model relates to an exempt from pneumatic tire technical field, concretely relates to exempt from pneumatic rubber tire.

Background

A tire is a ground-rolling circular ring-shaped elastic rubber article mounted on various vehicles or machines. The tires currently in use are generally pneumatic tires, and some tires are non-pneumatic tires.

These tires also have the following problems during use:

1. the tire is inflatable, easy to puncture and burst, and short in service life.

2. The stiffness of tire is not enough, and under the bearing state, the area of contact of tire and ground increases to lead to the frictional force increase, the rolling resistance is great, exempts from pneumatic tire simultaneously because the dead weight is great, more can aggravate the area of contact of tire and ground, still can increase the frictional force of tire and ground.

3. The conventional tire is inconvenient for the vehicle to run at night.

To this end, we propose a non-pneumatic rubber tire.

(III) advantageous effects

The embodiment of the utility model provides an exempt from to aerify rubber tire. The method has the following beneficial effects:

1. replace traditional inflatable inner tube of a tyre through foaming child core, improve the bearing capacity, the puncture-proof can also reach the effect of preventing the flat tire simultaneously, has improved the life of tire.

2. The stiffness of the tire can be improved, the elasticity of the tire is further improved, the contact with the ground is reduced, and the moving resistance is reduced. After the tire bears the load, the tensile force of the foamed tire core is opposite to the force of the sunken subpost of the tire body, so that the tensile amount of the foamed tire core can be reduced, the stiffness of the foamed tire core can be improved, and the elasticity of the tire can be improved.

3. All be provided with the casing king post between two casing subpillars, the casing king post can provide the fore-and-aft holding power of tire, improves the bearing effect of tire then, improves the stiffness of tire, improves the elasticity of tire then.

4. The rubber foaming material is adopted by the foaming tire core, so that the elasticity of the tire is improved again, and the moving resistance is reduced.

5. The main post of the tyre body is bonded with the reflective sticker, so that the safety of the vehicle running at night can be improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1:

referring to the attached figures 1-3, the inflation-free rubber tire comprises a tire casing 1 and a tire root 2, wherein the tire casing 1 is sleeved on the tire root 2, and is characterized in that a foaming tire core 3 which is annularly distributed is arranged in the tire casing 1; replace traditional inflatable inner tube of a tyre through foaming child core 3, improve the bearing capacity, the puncture-proof can also reach the effect that prevents the flat tire simultaneously, improves life, and foaming child core 3 adopts rubber foam, improves the elasticity of tire, reduces the moving resistance.

In this embodiment, as shown in fig. 1-3, a plurality of carcass sub-columns 12 recessed in an arc shape toward the foamed carcass core 3 are circumferentially distributed on both sides of the carcass 1, and a carcass main column 11 is disposed between the two carcass sub-columns 12, when the tire bears a load, the tire will receive a pressure F of the wheel hub and a reaction force F of the ground, the inner foamed carcass core 3 is converted into a tensile force F2 after receiving a bidirectional F pressure, and drives the foamed carcass core 3 to stretch toward both sides, and the cambered carcass sub-columns 12 convert the received F into a tensile force F1 moving toward the foamed carcass core 3 after receiving the bidirectional F pressure, so that a tensile force F2 of the foamed carcass core 3 is opposite to a tensile force F1 generated by the recessed carcass sub-columns 12, thereby reducing a tensile amount of the foamed carcass core 3, improving stiffness of the foamed carcass core 3, and improving stiffness of the foamed carcass core 3, will improve the elasticity of tire, reduce the contact with ground, reduce the moving resistance, still can prevent to foam the child core 3 after reducing the horizontal tensile force of foaming child core 3 simultaneously and damage, improve the life of foaming child core 3.

In this embodiment, as shown in fig. 2 and 3, the arc of the subplumn recess of the tire casing is between 10 ° and 40 °, the arc can be adjusted according to the size of the tire, and the larger the arc, the larger the force F1 that is stretched into the foamed tire core 3, and the smaller the arc is.

In this embodiment, as shown in fig. 1, the main tire body post 11 is bonded with the reflective sticker 13, which can improve the safety of the vehicle during night driving.

In this embodiment, as shown in fig. 1, the sidewall of each of the two ends of the tire root 4 is connected with a plurality of tire root anti-slip threads 41.

Example 2:

the difference from the embodiment 1 is that the foamed tire core 3 is a pneumatic tire core, the same casing sub-column 12 is also adopted, the stiffness of the pneumatic tire can be improved, and because the stress principle of the pneumatic tire core is consistent with that of the foamed tire core 3, the stiffness of the pneumatic tire can be improved by adopting the cambered surface design of the casing sub-column 12.
