Embodiment 1

[0033] Such as figure 1 , 2 shown.

[0034] An automatic explosion-proof spare wheel in a tire, which is mainly composed of an elastic inner ring, an outer ring and an air bag, etc., the spring outer ring is connected by an outer support 9 and can be stretched, and the inner ring is composed of an inner support 8 and is fixed by a fastening ring 3 On the hub 1, the fastening ring 3 can be made of steel wire or carbon fiber. figure 2 It is a schematic diagram of the mechanism of the tire in the depressurized state. The outer ring of the spare wheel is connected by a plurality of outer supports 9 to form a stretchable elastic body. The lower end of the outer supports 9 can slide between the BCs of the inner supports 8. There should be a certain amount of elastic force, and the two elastic sides of the outer support 9 have enough elastic force F2 to ensure that the inner support 8 can bounce up instantly, and be clamped and kept at point B, and the vehicle weight is jointly bo...

Embodiment 2

[0037] Such as image 3 , 4 shown.

[0038]In this embodiment, the inner ring and the elastic outer ring are designed as two parts, and the size of the outer ring is adjusted by sliding the elastic outer ring on the inner ring, or the inner ring and the elastic outer ring can be connected as a whole, and the inner ring 8 to change the size of the elastic outer ring 9, such as image 3 As shown, when the tire pressure is normal, the air pressure will press the inner ring 8 to bend and deform, while the elastic outer ring 9 is pressed inward to shrink, and the outer ring is locked by the buckle 16 after being compressed in place. When the tire loses air pressure, the buckle 16 is disengaged, and becomes as shown in Figure 4 under the action of the elastic force. When receiving the pressure of the tire surface, the outer side of the deformed part is non-extended, and the inner side is non-compressed, and cannot be bent inward. The spare wheel is in working condition.

Embodiment 3

[0040] Such as Figure 5 , 6 shown.

[0041] This embodiment is more suitable for high-width ratio tires. The fixed support is formed by the inner support 11 and the inclined support 12. The lower end of the inclined support 12 is connected with a small push rod 15, and the lower end of the inner support is clamped at the K point, so that the inner support is fixed. , When removing the tire, push the outer edge of the tire, and use the small push rod to release the oblique support from the K point of the inner support. At this time, the inner support can bend inward, and further push the tire edge into the deep groove of the wheel hub, thereby removing the tire.

[0042] The airbag 7 of the present embodiment can be placed between the inner and outer supports, such as Figure 5 , when the tire pressure is normal, use the tire pressure to compress the outer support to point B and lock it in place. Once the tire loses pressure, the outer support will be released from point B, ...

Abstract

The invention relates to a vehicle tyre inner automatic broken-proof extra wheel. The feature is that it includes a flexible external outer ring between tyre and hub, and an inner ring supporting the outer ring. The inner ring and outer ring would contracting between tyre and hub under the effect of normal pressure, and a suitable space is also set to avoid inner wall contacting to outer ring. When the tyre is broken, the outer ring would be bounced to support the corresponding weight of the vehicle to keep balance and avoid accident. The invention is benefit to improve the safety and comfort of wheel.

Description

technical field [0001] The invention relates to a safety spare device for automobile tires, which can automatically use a temporary spare tire in a very short time when the tire loses air pressure, especially when a tire blows out while the automobile is running at high speed, so as to keep the automobile in balance. Avoid accidents, play the role of explosion-proof safety spare tires, and at the same time ensure that it can continue to travel a sufficient distance to the repair shop without changing tires on the way. In case of a flat tire, it will be used as a spare tire automatically without changing the tire. Background technique [0002] Existing car tires are generally pneumatic tires. Good comfort and low resistance are the main advantages of pneumatic tires. At present, there is no better way to replace pneumatic tires. However, pneumatic tires also have disadvantages. Once the tire leaks and loses air pressure, the car It cannot be used normally, and the spare tire...
