Abstract

A special anti-explosion type is composed of external tyre, rim, and multiple shaped leaf springs filled in the cavity between external tyre and rim. Said rim is radially divided into primary and secondary rims. The lug plates are arranged on the interface between primary and secondary rims for screw bolt-connetion. Its advantages are high load bearing power and not exploding.

Description

Extraordinary trouble-proof tire

One, technical field

The present invention relates to the transportation and communication tire, especially motor tire is made the field.

Two, background technology

Tire probably can be divided into 8 kinds by vehicle classification.As passenger car tire, tyre for light truck, goods carrying vehicle and motorcoach tire, farm vehicle tire, Off-the-road tire, industrial truck tire, aircraft tyre and motor cycle tire etc.On structure, tire can be divided into diagonal tyre and radial-ply tyre two big classes again.Generally all belong to tube-tyre, it mainly is made up of wheel rim, the inner tube of a tyre, cover tire.Tire is one of parts of automobile, and it will play following four kinds of effects in the middle of running car: the one, and bearing load; The 2nd, produce propulsive effort and braking force; The 3rd, buffering and shock-absorbing; The 4th, change vehicle traveling direction.It is important completely that tire seems in the parts of whole automobile: after a people had sat on the automobile the inside, so, this people had in fact just given the automobile in travelling fully, and also can be described as in fact, this people has just all given four tires.In case blow out, promptly the inner tube of a tyre of tire is punctured by tip and hard object, and air will run off suddenly from the inner tube of a tyre, tends to cause the serious accident of car crashes such as overturning, " taking the least important seat at a square table ".In addition, also have a kind of vacuum tyre (nineteen thirty, Michelin made first vacuum tyre, also was air tyre), in essence, it should belong to tube-tyre.It is only molten for one the inner tube of a tyre of another kind of material and cover tire, and promptly its cover tire inner face posts one deck sealed Cellophane (the general oxidation butyl rubbers of using) tightly.When things such as nail one thrust, air is when leak in the hole, glued membrane shrinks along with the outflow of air at once and gets lodged in the hole in the tire, therefore, air can not run off suddenly, air can only be from being spilt by the place stung at leisure, can give to drive plenty of time and handle, and avoided unexpected gas leakage and cause serious accident such as vehicle rollover.

Three, summary of the invention

The purpose of this invention is to provide a kind of extraordinary trouble-proof tire, be intended to the possibility of stopping to blow out.Purpose of the present invention is realized by the following technical programs: a kind of extraordinary trouble-proof tire, comprise cover tire, wheel rim, also have and be positioned at the cover tire inner chamber, be fixed on a plurality of " king " font leaf springs made by spring plate on the wheel rim whole circumference face, the upper and lower bottom surface of leaf spring is respectively the curved surface that coincide substantially with cover tire top underside and wheel rim periphery.

Above-mentioned wheel rim radially is divided into main wheel circle and accessory whorl circle, and the adjacent position of major and minor wheel rim is respectively arranged with the otic placode for Bolt Connection.

In the above-mentioned design, leaf spring is fixed a circle along wheel rim whole circumference face, a structure and a leaf spring inner bag; The present invention replaces original inflatable inner tube with the leaf spring inner bag, on structure, tire of the present invention is not done big change in the cover tire direction (only has little adjustment, rubber registration mast and back-up ring as the cover tire inner face), kept original airtyred ground ability of grabbing, thereby the present invention has kept airtyred following function: promptly produce propulsive effort and braking force; Change vehicle traveling direction etc.Secondly, the leaf spring inner bag that is made of " king " font leaf spring has airtyred buffering and vibration-absorbing function equally; Moreover leaf spring inner bag of the present invention has the ability of higher bearing load than airtyred inflatable bladder.In general, there is not the problem of vacuum tyre in the present invention owing to there is not inflatable inner tube, even be pierced under the situation of hole at cover tire, can continue the hundreds of kilometer that travels yet, and does not have vacuum tyre gas leakage problem, the problem that does not exist inflatable inner tube to blow out and overturn.

Tire of the present invention proves in the test-drive (having travelled about 600 kilometers) on the spot through the inventor, under the ups and downs situation in road surface, find the sensation obviously jolt, because the problem that this tire can not blown out, do not exist aerating to replenish the problem of air pressure yet, so, in the driving procedure, make chaufeur be full of the confidence and the sense of security.

Four, description of drawings:

Fig. 1 is the fragmentary cross-sectional view along the tire axial direction of the present invention;

Fig. 2 is the block diagram of the leaf spring inner bag that is made of leaf spring shown in Figure 1;

Fig. 3 is the front view of leaf spring shown in Figure 1;

Fig. 4 is the section-drawing along the A-A line shown in Figure 1.

Five, the specific embodiment

Fig. 1 Fig. 4 illustrates, leaf spring 6 is done by the spring plate steel of No. 45 1.5mm, shape is as " king " font, a plurality of leaf springs are fixed on the whole circumference face of wheel rim (can regard wheel rim as a column, down together), a plurality of leaf springs constitute a leaf spring inner bag (see figure 2), to replace existing inflatable bladder, the leaf spring inner bag is positioned at the cover tire inner chamber, the upper and lower bottom surface (Fig. 4) of each leaf spring is the curved surface that coincide substantially with cover tire top underside and wheel rim periphery respectively, in the reality, the upper and lower bottom surface of leaf spring and the degree of agreement of cover tire and wheel rim are higher as far as possible for well.Each leaf spring preferably connects firmly with wheel rim mutually through bolt 8 (referring to Fig. 3).For installing and removing conveniently, wheel rim radially is divided into main wheel circle 2a and accessory whorl circle 2b, the adjacent position of major and minor wheel rim is respectively arranged with otic placode 3a, 3b, otic placode is a circle, be provided with packing ring 4, two otic placodes between two otic placode 3a, the 3b of major and minor wheel rim and fix (adopting 10 bolts on as whole circumference) to reach the air-tightness requirement through bolt 5; Be provided with rubber registration mast 1c (Fig. 4) between cover tire 1 top underside, adjacent two leaf springs, the and arranged on left and right sides of cover tire inner face leaf spring is respectively arranged with back-up ring 1a, 1b (Fig. 1), better scheme is, rubber registration mast 1c and two back-up ring 1a, 1b adopt whole (integrated) setting with cover tire.Among Fig. 4, the main wheel circle is provided with valve 7 (valve is the same with existing tire, just illustrates among Fig. 4, and does not require that valve is located at the wheel rim medium position), and valve stretches into the cover tire inner chamber.In the making, require the tight interlock in junction surface of cover tire and wheel rim, (cooperate valve, packing ring etc.) like this, tire of the present invention also can be inflated between cover tire and wheel rim by valve, to strengthen and to improve buffering and damping performance.

For dolly, can adopt 10 leaf springs to constitute leaf spring inner bag (referring to Fig. 2).

Concerning cart, can on the basis of as shown in Figure 2 row's leaf spring, increase by row's leaf spring again around the wheel rim periphery, constituting two row's formula leaf spring inner bags, and two row's leaf spring mutual dislocation are provided with.The adjacent position of two row's leaf springs can fix to connect and handle, to improve globality.

The present invention does not get rid of the use as the others tire certainly mainly as motor tire.
