Abstract

The utility model relates to an explosion-proof tire, particularly a bridge explosion-proof tire, comprising a tire body. Annular inner sidewalls are arranged on both sides of the inner cavity of the tire body; the annular internal sidewalls divide the inner cavity of the tire body into an annular main pressure bearing cavity in the center and closed annular auxiliary pressure bearing cavities on the two sides; the two inner sidewalls are respectively provided with valve pins. The utility model is of simple structure and easy installation, and has good explosion-proof effect because of multi cavities to improve the personnel safety; meanwhile, by using the structure of stone arch bridge, the utility model further enhances the loading capacity and lowers the costs of transportation; thanks to good exchange interchangeability, the utility model is widely applicable to various types of vehicles, particularly applicable to cars of all-steel meridian tires; the utility model is easy to promote and implement, with obvious social and economic benefits after popularization.

Description

The bridge-type trouble-proof tire

One. technical field: the utility model relates to a kind of trouble-proof tire, particularly relates to a kind of bridge-type trouble-proof tire.

Two. background technology: along with China's sustained and rapid development of economy, governments at all levels continue to increase the investment of capital construction, especially the construction investment to highway bridge increases substantially especially, therefore China Higher level highway and express highway are more and more, this has improved the speed that people ride greatly, save the journey time greatly, reduce the fatigue of long-term travel, increase work efficiency simultaneously.But, also there are some drawbacks in this situation: present most of inflatable tires inside has only an inflatable cavity, no matter be tube-tyre or tubeless tires, as long as explosion takes place in any position, will cause whole tire not work, because the speed of a motor vehicle is very fast, luxury car particularly, when the tire generation explosion of vehicle or when disappointing, often cause serious traffic accident, jeopardize people's life security.Show " from the statistics of domestic tens main traffic accidents, the traffic accident that tire fault causes accounts for the over half of whole traffic accident " according to the relevent statistics, this shows the importance of tire.At this situation, people work out trouble-proof tire, as Chinese patent CN2415950Y, ZL00203910 discloses a kind of " standby each other inflatable tire and wheel rim thereof ", it mainly comprises tire body 1, cavity 2 and wheel rim 5 thereof, because the effect of tire body 1 and wheel rim 5 is with the two or more cavitys 2 of tire body 1 inner formation; Chinese patent CN2507679Y and for example, ZL01237599.3 discloses a kind of " multi-cavity chamber trouble-proof tire ", is to make multiple tracks compartment and isolated chamber independently separately in tire, and tire is connected with the purpose made wire loop.Above-mentioned tire is when a chamber generation explosion, and other cavity can work on, and has solved the harm that the tire blow-out causes, they all need to dispose the purpose made wheel rim, structure is complicated, can not exchange with the wheel rim of conventional tyre, general, influences its promotion and implementation.

Three. the utility model content:

The purpose of this utility model: overcome the defective of prior art, provide a kind of simple in structure, easy for installation, improve the bridge-type trouble-proof tire of load-carrying capacity.

The technical solution of the utility model: a kind of bridge-type trouble-proof tire, contain tire body, wherein be provided with the annular inboard wall in the inner chamber both sides of tire body, this madial wall is divided into the annular main pressure pocket of central authorities and the secondary pressure pocket of closed ring of both sides with tyre cavity, is respectively equipped with valve inside on two madial walls.

The cross-sectional plane of the secondary pressure pocket of described closed ring can be crescent.

The beneficial effects of the utility model:

1. the utility model is simple in structure, and is easy for installation, and explosion-proof effect is good.Employing is respectively equipped with madial wall in tire body inner chamber both sides, and madial wall and lateral wall surround two inflatable cavitys of osed top annular, are respectively equipped with valve inside on two madial walls.This tire is main pressure-bearing chambers of central authorities, the multi-cavity cell structure of two the secondary pressure-bearing chambers in both sides, be not communicated with mutually between each chamber, when a chamber generation explosion, the gas of cavity is unaffected in addition, can work on, so explosion-proof effect is good, reduce traffic accident, improve safety of persons.Owing to there is not a purpose made wheel rim, so its simple in structure and conventional tyre can exchange in intercommunication, installs very convenient.

2. the utility model has improved tyre capacity.Adopt the version of stone arch bridge on the architectural history, further improve load-carrying capacity, reduced traffic cost simultaneously.

3. the utility model applied range.Owing to have interchangeability, therefore be widely used in various vehicles, be specially adapted to the car of all-steel meridian shape tire, be easy to promote, implement easily, have obvious social and economic benefits after the popularization.

Four. description of drawings:

Fig. 1 is the structural representation of bridge-type trouble-proof tire

Five. the specific embodiment:

Embodiment: referring to Fig. 1, tire body 1 is a car all-steel meridian tire among the figure, its inner chamber both sides are provided with annular inboard wall 2, and this madial wall 2 is divided into the annular main pressure pocket 3 of central authorities and the secondary pressure pocket 4 of closed ring of both sides with tyre cavity, is respectively equipped with valve inside 5 on two madial walls 2.The cross-sectional plane of the secondary pressure pocket 4 of closed ring can be crescent.Tire body 1 matches with vehicle rim 6.

During installation, inflate in secondary pressure pocket 4 by valve inside 5 earlier, its pressure is less than standard pressure (being about 0.6 standard pressure), then tire body 1 is installed on the axletree, the sealing inflation spool (not drawing among the figure) that is provided with by wheel rim 6 is inflated to main pressure pocket 3 again, make it reach standard pressure, the air pressure of tire body 1 is in state of equilibrium thereupon, and this moment, tire can use.

Claims

1. bridge-type trouble-proof tire, contain tire body, it is characterized in that: the inner chamber both sides of tire body are provided with the annular inboard wall, and this madial wall is divided into the annular main pressure pocket of central authorities and the secondary pressure pocket of closed ring of both sides with tyre cavity, is respectively equipped with valve inside on two madial walls.

2. trouble-proof tire according to claim 1 is characterized in that: the cross-sectional plane of the secondary pressure pocket of closed ring can be crescent.
