Description

Air leakage protection tire and using method

Technical Field

The invention relates to the technology of automobile tires, in particular to a leakage protection tire and a use method thereof.

Background

Vacuum tires are tubeless pneumatic tires, also known as "low pressure tires" and "pneumatic tires". Vacuum tires have been increasingly used in bicycles, motorcycles, cars, coaches, and trucks in recent years. The vacuum tire has higher elasticity and wear resistance, and has good adhesive force and heat dissipation performance. In particular to an all-steel radial vacuum wheel which is popularized to the logistics transportation industry by the national committee for economy and durability and the national tire association.

The vehicle is susceptible to a blowout event during operation, particularly at high speeds. After the tire burst occurs, the relatively high air pressure is instantaneously lost in the tire, the tire is rapidly shrunken under the action of gravity, the vehicle continues to advance at a high speed, and the hub rotates at a high speed, so that the tire slides out of the hub, and the vehicle is out of balance and is extremely easy to have a safety accident.

There are also some emergency devices for tire burst: the Chinese patents (publication numbers: CN105599546A, CN105774415A, CN105667221A, CN105584301A and CN105667222A respectively) of the applicant Wang Huimin disclose supporting devices which are arranged on the circumference of a wheel hub and are positioned in a tire, wherein the supporting devices are provided with cushion blocks, each cushion block consists of an upper metal material layer, a lower metal material layer and a middle miniature air bag layer, and when an inductor senses the air leakage of the tire, the miniature air bags are inflated instantly, so that the wheel hub is prevented from being impacted by the ground to generate traffic accidents. But such support means have problems: the supporting device is arranged on the outer circumference of the hub, and the production process is unchanged; the three-layer structure is adopted, and the structure is complex; when the automobile bursts and the miniature air bag is not inflated instantly, the upper and lower metal material layers are impacted suddenly, and the upper and lower metal material layers may be broken.

As shown in fig. 2: the top 21 of the cushion block 20 is lower than the toe 12 of the tyre body 10, so that the air bag space of the air leakage protection tyre is communicated, when the automobile tyre running at high speed leaks, the hub is clung to the top 21 of one cushion block 20, the air pressure in the tyre is increased, and the air pressure can be released to the inner air bag space of the whole tyre; if the top 21 of the pad 20 is flush with the toe 12 of the tire body 10 or the top 21 of the pad 20 is higher than the toe 12 of the tire body 10, the hub and the top 21 of the pad 20 are pressed more tightly when the tire of the vehicle running at high speed is deflated, so that the air pressure between the pad 20 and the pad 20 is locally increased, resulting in the occurrence of a flat tire.

On the other hand, when an automobile tire encounters a spike material such as a spike, the position where the spike material most easily pierces the tire body 10 is mainly located at the thinnest position at the crown of the tire body 10. Because the cushion block 20 is arranged in the tire body 10, the thinnest position of the crown of the tire body 10 is positioned at the gap between the cushion block 20 and the cushion block 20; the cushion block 20 has a certain thickness, and the whole cushion block 20 is difficult to be punctured by a sharp needle substance along the thickness direction, so that the tire leaks; therefore, the cushion block 20 is arranged in the tire body 10, so that the probability of the automobile tire being punctured by the spike material such as the iron nail can be greatly reduced.

Preferably, the first side 22 and the second side 23 of the pad 20 are connected to the sidewall inner wall 13 of the tire body 10; the third side 24 and the fourth side 25 of the pad 20 are inclined surfaces; the top 21 of the cushion block 20 is an arc surface.

Preferably, the number of the cushion blocks 20 is 8, 10 or 12; the plurality of pads 20 are uniformly disposed along the inner wall 11 of the tire body 10.

In practice, the number of pads 20 may be set to 8, 10 or 12 according to the size of the actual tire body 10, the use environment of the tire, the load bearing, and the like. Since the spacer 20 also has a certain weight, it is necessary to uniformly distribute the plurality of spacer 20 on the inner wall 11 of the tire body 10, ensuring that the tire can be used normally.

Preferably, the tire body 10 is a vacuum tire.

Preferably, the inner wall 11 of the tyre body 10 is provided with a glue layer 30; the cushion block 20 is disposed on the surface of the adhesive layer 30.

Preferably, the tire body 10 is disposed separately from the pad 20, and in practice, the air leakage protection tire provided by the present invention provides at least two realizations:

the tire body is bonded with the cushion block by glue, and if the tire body has the problems of tire burst and the like, the tire body cannot be used continuously and needs to be replaced, the specific using method is as follows: replacing the damaged tire body; uniformly dividing a cushion block placing area on the inner side of a new tire containing the polymer organic memory glue according to the circumference of the tire and the side length of the cushion block; heating the placement area by using a heating blowing device to melt the high polymer organic memory glue; and attaching the cushion block to a placement area of the melting memory glue, naturally cooling, mounting the air leakage protection tire on a hub, and replacing the whole wheel on an automobile.

According to the method, the characteristics of the existing tire containing the polymer organic memory glue are utilized, namely, the inner side of the tire contains the memory glue with high viscosity, no additional tools are needed, and only a user needs to store a plurality of standby cushion blocks on a vehicle, so that the cushion blocks can be installed at any maintenance point. In the prior art, the explosion-proof tire is not standard and can not be replaced at any time at any automobile maintenance point.

Another usage mode is that the tire body 10 and the pad 20 are structurally connected with each other: preferably, the inner wall 11 of the tyre body 10 is uniformly provided with inverted T-shaped grooves 50, and the upper layer of the inverted T-shaped grooves 50 is provided with saw teeth; an inclined surface 51 is arranged at the end step of the inverted T-shaped groove 50; the bottom of the cushion block 20 is provided with a T-shaped bulge 60 along the length direction, and the lower layer of the T-shaped bulge 60 is provided with saw teeth corresponding to the upper layer of the inverted T-shaped groove 50; the length of the inverted T-shaped groove 50 is greater than the length of the T-shaped protrusion 60.

When the tire body 10 is burst and can not be used continuously and needs to be replaced, the cushion block 20 can be disassembled for recycling.

As shown in fig. 7 and 8: a plurality of inverted T-shaped grooves 50 are uniformly formed in the inner wall 11 of the tire body 10, the upper layers of the inverted T-shaped grooves 50 are arranged in a zigzag shape, and one or both ends of each inverted T-shaped groove 50 are provided with inclined surfaces 51; the bottom of the cushion block 20 is provided with T-shaped bulges 60 along the length direction, and the lower layer of the T-shaped bulges 60 is provided with saw teeth corresponding to the upper layer of the inverted T-shaped groove 50; the length of the inverted T-shaped groove 50 is greater than the length of the T-shaped protrusion 60. Preferably, the length of the inverted T-shaped slot 50 is one serration longer than the length of the T-shaped protrusion 60. To install the spacer 20 into the tire body 10, the saw teeth of the lower layer of the T-shaped protrusion 60 are aligned with the saw tooth grooves of the upper layer of the inverted T-shaped groove 50, and then the spacer 20 is pressed into the inverted T-shaped groove 50, and then the spacer 20 is moved toward one end thereof, so that the saw teeth of the lower layer of the T-shaped protrusion 60 are aligned with the saw teeth of the upper layer of the inverted T-shaped groove 50, and the saw teeth of the lower layer of the T-shaped protrusion 60 are blocked by the saw teeth of the upper layer of the inverted T-shaped groove 50, so that the spacer 20 does not fall off the inner wall 11 of the tire body 10. Since one or both ends of the inverted T-shaped groove 50 are provided with the inclined surface 51, the distance between the bottom surface of the inverted T-shaped groove 50 and the inner wall 11 of the tire body 10 becomes gradually smaller, thereby clamping the T-shaped protrusion 60, so that the head block 20 does not fall off. On the other hand, the first side surface 22 and the second side surface 23 of the pad 20 are in contact with the sidewall inner wall 13 of the tire body 10, so that the friction between the pad 20 and the inside of the tire body 10 is improved, and the pad cannot move or fall off during the use of the tire. Meanwhile, before the automobile tire is used, the space between the tire body 10 and the hub is filled with air, the tire is internally provided with enough tire pressure, and the cushion block 20 can be tightly attached to the inner wall 11 of the tire body 10.

When the tire is specifically used, the damaged tire is replaced; aligning the saw teeth of the lower layer of the T-shaped bulge at the bottom of the cushion block with the saw tooth grooves of the upper layer of the inverted T-shaped groove at the inner side of the new grooved wheel tire body with the inverted T-shaped bulge; applying pressure to the cushion block along the direction vertical to the inner wall of the tire body, so that the T-shaped bulge enters the inverted T-shaped groove; the cushion block moves towards one side of the inverted T-shaped groove, so that the saw teeth of the lower layer of the T-shaped bulge are aligned with the saw teeth of the upper layer of the inverted T-shaped groove; and (3) mounting the air leakage protection tire for placing the cushion block on the hub, and replacing the whole wheel on the automobile.

The method enables the cushion block 20 to be recycled, is convenient to install and detach, and avoids waste of materials.
