Abstract

The utility model relates to a wheel without an inner tire for a car. An annular rigid wheel is arranged on the outer surface of a wheel rim of a steel ring and form the integration with the wheel rim, the size of the outer diameter of the annular wheel is at least 2 c m higher than the size at the maximum diameter point of the outer surface of the wheel rim, and meanwhile, the size of the outer diameter of the annular wheel is at least 1 c m smaller than the size of the inner diameter of an outer wheel tire. The utility model can effectively solve the problem that the wheel without an inner tire is easy to appear traffic accidents, such as rolling accidents, etc. and can not run when the air leakage occurs, and has ideal effect.

Description

Shellproof burst-proof tyre

The utility model relates to a kind of automotive wheel, the inner tube-free wheel that particularly a kind of automobile is used.

At present, on some high-grade utility vans, car and bullet-proof car, all used inner tube-free wheel.It is that cover directly is sleeved on the steel ring, and being full of gas in the space between steel ring and cover can travel, and it has avoided the car inner tube of a tyre easily to poke and worry such as tire patching.Although but inner tube-free wheel is not easy to be poked, also still there is the possibility of leaking, can't travel as making tire flat under gunslinging, pinning or other the sudden external force effect, even cause traffic accidents such as overturning in driving states lower whorl threatened abortion conductance.In addition, existing wheel in case of emergency since can't tire patching or change of wheels then can only cast anchor, can't walk.

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of safe and reliable, even the shellproof burst-proof tyre that cover gas leakage also can be travelled.

Technical solution of the present utility model:

A kind of shellproof burst-proof tyre, it includes steel ring (3) and the rubber cover of being made up of wheel rim (1), spoke (2) (4), it is characterized in that on wheel rim (1) outside face of steel ring (3), being provided with rigid ring wheel (5), it and wheel rim (1) are an integral body, and the size of the external diameter of this ring wheel (5) exceeds 2 centimeters than the maximum gauge place of wheel rim (1) outside face at least, simultaneously again than the internal diameter of cover (4) to when young 1 centimeter.

The utility model adds a ring wheel first again on steel ring, it and steel ring are an integral body, and is positioned at cover inside.In case when cover leaked gas owing to situations such as gunslinging, pinnings like this, ring wheel was with regard to the generation effect, it has avoided cover flat going down and the phenomenon of traffic accidents such as overturnings grade easily takes place quickly on the one hand, can replace cover on the other hand and make wheel continue to travel.This in particular cases is very useful at some, punctures cover as the ruffian, and because in critical condition can't tire patching or just can rely on ring wheel to continue to travel during change of wheels, to be out of danger.The utility model novel structure is simple, dependable performance, and safety improves greatly, ring wheel in it is inoperative in the cover normal circumstances, make wheel not lose its effect in case its just alternative immediately cover of gas leakage takes place, really had functions such as shellproof, explosion-proof, effect is very good.

Fig. 1 is the structural representation that partly cuts open of the present utility model;

Fig. 2 is that the A of Fig. 1 is to the structure for amplifying scheme drawing.

As Fig. 1,2, the size of the ring wheel in the utility model (5) is that the 2-3 centimetre is advisable with its external diameter and the spacing between cover (4) internal diameter preferably, in case cover (4) gas leakage like this, ring wheel (5) promptly contacts with ground.Ring wheel (5) is preferably disposed on the middle minimum groove (6) of wheel rim (1) outside face of steel ring (3) and locates, and its width also width with this minimum groove (6) is identical.For ease of installing, ring wheel (5) should be the branch solid, it divides, and three-dimensional piece is several to be decided according to needs, generally can be divided into three or four arcs branch solids, also can be divided into more polylith, during installation each piece branch solid is sleeved on wheel rim (1) outside face, its each adjacent all by lock ring behind the bolted connection on wheel rim (1) outside face, looping wheel (5).For preventing that ring wheel (5) is not enough with the lock ring degree of wheel rim (1), in case occur slide relative under steam, keyway arrangements (7) can be set between them, can effectively solve the problem of slide relative like this.Ring wheel (5) adopts hard material to make, make it to have stronger hardness, automobile is punctured when gas leakage in case cover (4) occurs under steam like this, ring wheel (5) promptly and ground supports, traffic accidents such as overturning can not take place, safety improves greatly, mends cover (4) or change of wheels then and gets final product.Under special circumstances, if maybe can't repair cover (4) or change of wheels nowhere the time, then because the existence of ring wheel (5) is arranged, automobile still can continue to travel, and solved does not have the difficult problem that the inner bag wheel can only cast anchor this moment in the past, and is practical.

Claims

1, a kind of shellproof burst-proof tyre, it includes steel ring (3) and the rubber cover of being made up of wheel rim (1), spoke (2) (4), it is characterized in that on wheel rim (1) outside face of steel ring (3), being provided with rigid ring wheel (5), it and wheel rim (1) are an integral body, and the size of the external diameter of this ring wheel (5) exceeds 2 centimeters than the maximum gauge place of wheel rim (1) outside face at least, simultaneously again than the internal diameter of cover (4) to when young 1 centimeter.

2, by the described shellproof burst-proof tyre of claim 1, it is characterized in that the external diameter of ring wheel (5) and the spacing between cover (4) internal diameter are preferably the 2-3 centimetre.

3, by the described shellproof burst-proof tyre of claim 1, it is characterized in that the minimum groove (6) that ring wheel (5) is preferably disposed in the middle of wheel rim (1) outside face of steel ring (3) locates, its width also width with this minimum groove (6) is identical.

4, by the described shellproof burst-proof tyre of claim 1, it is characterized in that ring wheel (5) should be the branch solid.
