Example Embodiment

[0014] Example 1:

[0015] See figure 1 , Is a schematic diagram of the upper cross-sectional structure of the explosion-proof, bullet-proof, non-pneumatic tire of the present invention, which is composed of a tire 1 and a non-pneumatic inner tube 2 with three horizontally arranged cavities 3. The cross-section of the non-pneumatic inner tube 2 is olive-shaped. The tire 1 is composed of a tread 5 made of non-foamed nano-polyurethane rubber and a carcass 6 made of foamed nano-polyurethane rubber. The two opposite sides of the carcass 6 are respectively provided with heat dissipation holes 4 communicating with the cavity 3. A radial cord 7 is provided between the inner tube 2 and the inner tube 2. Two beads 8 are provided in the carcass 6. Four grooves 9 are provided on the inner edge of the casing 1.

[0016] When preparing the tire of Example 1, rubber or reclaimed rubber with low internal heat generation and good stability is first selected to make a non-inflatable inner tube 2 ...

Example Embodiment

[0021] Example 2:

[0022] Refer to image 3 , Is a schematic diagram of the upper cross-sectional structure of another explosion-proof, bullet-proof, non-pneumatic tire of the present invention, which is composed of a tire 1 and an inflatable inner tube 2 with a cavity 3, wherein the inflatable inner tube 2 has seven communicating cavities 3, and the cavity 3 constitute a honeycomb structure, the cross section of the non-inflatable inner tube 2 is circular. The tire 1 is composed of a tread 5 made of non-foamed nano-polyurethane rubber and a carcass 6 made of foamed nano-polyurethane rubber. The two opposite sides of the carcass 6 are respectively provided with heat dissipation holes 4 communicating with the cavities 3 on the left and right sides. A radial cord 7 is provided between the outer tire 1 and the non-inflated inner tire 2. Two beads 8 are provided in the carcass 6. Other technical features are the same as in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses an explosion-proof and bulletproof inflation-free tyre which comprises an outer tube and an inflation-free inner tube, wherein the external surface of the inflation-free inner tube is wound with a meridian cord thread; the outer tube is sleeved on the inflation-free inner tube, and the inflation-free inner tube is provided with a plurality of communicated cavities; the two opposite side walls of the outer tube are equidistantly provided with a plurality of heat dissipation holes which are respectively communicated with the cavities; and the inside of the outer tube is provided with at least two steel tire beads. The tyre disclosed by the invention has the advantages that the heats generated in the tyre during the running of the tyre can be dissipated well; the tyre is inflation-free, bulletproof, anti-skidding, high in wear resistance, and not afraid of being punctured, and does not have a flat tire; and the tyre is good in comfortableness and safe and reliable in use.

Description

technical field [0001] The invention relates to an air-free tire. Background technique [0002] Most of the existing explosion-proof and bulletproof tires are pneumatic tires. When there are small pores in the tread, they can automatically replenish air or fill up the pores with glue, so that they can continue to travel for a certain mileage. The occasions of use are also mostly used in high-end cars, which have high requirements for comfort and safety, but they cannot be used after large holes appear. Most of the non-pneumatic tires are solid structures, which have the defects of large internal heat generation and poor heat dissipation during use, and the elasticity is not good, the comfort is poor, and the weight is relatively heavy. They can only be used on low-speed engineering vehicles and cannot be used. Used in medium and high speed motor vehicles. Contents of the invention [0003] The object of the present invention is to provide an explosion-proof, bulletproof ...
