Description

A kind of polymer material non-inflation anti-puncture anti-explosion tire

technical field

The utility model relates to a tire, in particular to an inflation-free, puncture-proof and explosion-proof tire made of polymer materials.

Background technique

Bicycles and electric vehicles have now become entertainment tools and green transportation tools for cycling enthusiasts. The biggest factor to be considered for bicycle tires and electric vehicle tires is their decompression and buffering functions, so inflated rubber tires have been used all the time. This tire meets people's needs for more comfortable and energy-saving vehicles in terms of performance, but there are also other problems. The disadvantage is that it is easy to be penetrated by sharp objects, that is, a tire blowout phenomenon, especially when driving on a rough road like a mountain, it is easy to have a tire blowout phenomenon. Once a similar situation occurs, it will not only pose a threat to the driving safety of the vehicle. It is a serious threat, and it also brings great trouble to the use of the vehicle; although the use of solid tires will not cause tire blowouts, the ability of solid tires to adapt to the road is poor, and it is easy to feel bumps when riding on rough roads. The ability is poor, and the resistance to riding is high.

The outer wall is made of rubber, which can improve the wear resistance of the tire case. The outer wall is provided with a tread pattern, which can improve the grounding elasticity of the outer wall, and under the action of a tangential force between the outer wall and the ground, the tread pattern blocks can produce relatively large tangential elastic deformation. As the tangential force increases, the tangential deformation increases accordingly, and the "friction effect" of the contact surface increases accordingly, thereby inhibiting the slipping or slipping tendency between the outer wall and the ground, and improving the braking performance, steering maneuverability and The normal performance of driving safety is reliably guaranteed, and the visual effect can be improved while enhancing the comfort. The middle part of the outer wall is provided with grooves along the circumferential direction, which can provide heat dissipation and drainage functions for the carcass.

The non-inflatable, puncture-proof and anti-explosion tires made of polymer materials can greatly reduce the throwing feeling of the vehicle and improve the driving stability during riding. At the same time, the tires have excellent deformation and rebound performance when subjected to longitudinal impact, Therefore, under low-adhesion off-road conditions, the deformation of the support structure can greatly increase the contact area between the outer wall and the ground, improve the adhesion of the tire, and form a small A small track effect helps the vehicle move forward smoothly.

detailed description

As shown in Figure 1, the utility model provides a kind of polymer material air-free anti-puncture anti-explosion tire, including carcass 1, outer wall 2 and two side walls 3 connecting the outer edge of carcass 1 and the outer edge of outer wall 2 , the tire case 1 is attached to the wheel hub, the outer wall 2 is in contact with the ground, and the outer wall 2 is arranged on the circumferential surface of the tire case 1. The tire case 1 is made of polymer thermoplastic resin, so that the weight of the tire is reduced and the strength is increased. Ride resistance while increasing rebound rate for improved comfort. A plurality of U-shaped holes 4 are evenly distributed along the circumferential direction on the side wall 3. On the one hand, the U-shaped holes 4 can still restore the original shape after being squeezed and stretched, so that the shape of the carcass 1 remains unchanged. On the one hand, the deformation of the U-shaped hole 4 is used to make the carcass 1 have excellent elasticity and cushioning force, and can fully withstand changes in pressure, so that the carcass 1 remains firm enough at any time, just like a traditional inner tube fully inflated , so that people are still as comfortable and light as riding traditional tires. The U-shaped hole 4 is arranged in the middle part of the side wall 3, which can well dissipate the heat generated when the tire casing 1 moves. When the tire case 1 bears the longitudinal load, the U-shaped hole can be fully compressed to increase the deformation of the tire case 1 and ensure comfort. The U-shaped hole 4 is set as a through hole passing through the side wall 3, which can not only reduce the weight of the carcass 1, but also reduce rolling resistance and improve comfort. Spokes are formed between two adjacent U-shaped holes 4, and the angle between the spokes and the outer wall 2 is set to 45°, so that each force on the tire case 1 can be shared by multiple spokes, and the rolling When the pressure can be transmitted linearly, it can achieve the same performance as a pneumatic tire. When tire case 1 is under lateral load, since the direction of force is parallel to the force direction of U-shaped hole 4, tire case 1 is fully supported by spokes, the lateral deformation of tire case 1 becomes smaller, and the strength of tire case 1 is improved. Cornering stiffness, which in turn improves the vehicle's lateral support and ensures handling stability. An assembly line is provided at the junction of the side wall 3 and the carcass 1, and a marking layer marked with an installation direction is provided on the side wall 3, which can indicate the installation position and direction.

The outer wall 2 is made of rubber, which can improve the wear resistance of the tire. The lack of air in the tire means that there will be no air leakage or tire blowout caused by being pierced by foreign objects, and the deformation of the U-shaped hole 4 can make the transition of the tire smoother and more stable when driving over obstacles. Moreover, the carcass 1 is made of polymer thermoplastic resin, so it can be reused, and the outer wall 2 can be refurbished to make it more environmentally friendly. The outer wall 2 is provided with tread patterns, which can improve the grounding elasticity of the outer wall 2 , and under the action of the tangential force between the outer wall and the ground, the tread pattern blocks can produce relatively large tangential elastic deformation. As the tangential force increases, the tangential deformation increases accordingly, and the "friction effect" of the contact surface increases accordingly, thereby inhibiting the slipping or slipping tendency between the outer wall 2 and the ground, and improving the braking performance, steering maneuverability and driving performance of the vehicle. The normal performance of safety is reliably guaranteed, and the visual effect can be improved while enhancing the comfort. The middle part of the outer wall 2 is provided with a groove along the circumferential direction, which can provide heat dissipation and drainage functions for the tire.

Due to the simplification of the structure of the polymer material non-inflatable anti-puncture anti-explosion tire, the energy loss caused by the repeated deformation of the tire during the movement is greatly reduced, and then the effect of improving the economy of the vehicle is achieved. And because the tires operate more stably during exercise, their wear resistance is also greatly improved.

The utility model is not limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes in its shape or structure, all have the same features as the application Or similar technical schemes all fall within the protection scope of the present utility model.
