Abstract

The utility model relates to ring canal inner tube which has the advantages and the characteristics of a rubber inner tube and is not required to be inflated. The ring canal inner tube is formed by a hard ring canal (2) and a rubber ring (1) which are assembled, is not afraid of cold or heat water and puncture and can be exchanged with rubber inner tubes of common bicycles, common motorcycles, etc.

Description

The endless tube inner tube of a tyre

The utility model relates to the non-inflatable endless tube inner tube of a tyre of a kind of not gas filed tire, particularly bicycle, motor bike.

Common rubber inner tube, the great advantage of its in-use performance is: flexible good, elasticity volume is big, and its is put into when moving in tire, can cushion the impact endurance test shock and the noiselessness of various bumpinesses effectively.Therefore it has obtained using widely in tyre industry.But, rubber inner tube also has a weakness of gas leakage easily, this weakness has been brought many worries to people at work, in order to solve inner tube of a tyre gas leakage problem, there are many people to drop into number of research projects for a long time, but from recent inquiry information that computer obtains: be used for the technological invention of the Uninflated inner tube of bicycle, motor bike at present, on feature performance benefit and cost advantage, compare with rubber inner tube, all also there is a little gap, therefore, multinomial technology in the invention can't be used widely and promote so far.

The purpose of this utility model is will provide a kind of to have the rubber inner tube feature performance benefit, and cost is low, and bearing capacity is big, is not afraid of bundle, is not afraid of cold and hot weather, the non-inflatable endless tube inner tube of a tyre that can exchange with the rubber inner tube of ordinary bicycle, motor bike.

The purpose of this practical full mold is achieved in that the endless tube inner tube of a tyre is by a hard endless tube and a soft rubber ring combination.During combination, rubber ring is fixed in the groove on the hard endless tube cylindrical mid point.When the endless tube inner tube of a tyre was put in the tire, rubber ring was clipped between cover tire and the hard endless tube.When therefore tire moved, the inside diameter surface of hard endless tube pressed closer the vehicle steel ring and supports gravity, cover tire opposing abrasion, and rubber ring then replaces inflating rubber inner tube of a tyre buffering antidetonation effectively.

Because adopt above scheme, the endless tube inner tube of a tyre not only possesses the resilient characteristic that rubber inner tube is arranged, but also possess non-inflatable advantage is arranged, its structure only is made of hard endless tube and rubber ring, so simple in structure easy to implement.

Below in conjunction with figure and embodiment the utility model is further specified.

Fig. 1 is that the master of first embodiment of the endless tube inner tube of a tyre looks and cutaway view.

Fig. 2 is that the master of second embodiment of the endless tube inner tube of a tyre looks and cutaway view.

Among the figure: 1-rubber ring, the hard endless tube of 2-, 3-reinforced rib.

Among Fig. 1, rubber ring (1) tightly is enclosed within the groove on the cylindrical dotted line of hard endless tube (2).Hard endless tube (2) is the hollow tubular made from highstrenghtpiston or other light hard material, and this manages flexible shaping, and the shape of groove on the cross section on its external diameter dotted line can be made multiple shape, but does in the arc-shaped best.Rubber ring (1) by elasticity preferably rubber make, its Zou Shi rubber and plastic hardness is preferably less than 30 degree, the cross sectional shape of this rubber ring (1) is joined work with the groove on the hard endless tube (2), but preferably makes round entity.

Embodiment among Fig. 2 is another embodiment of the present utility model.In this embodiment, increased reinforced rib (3) in the cross section of hard endless tube (2).The effect of reinforced rib is to bear carrying force, and according to the load-carrying needs of different automobile types, this reinforced rib is subjected to force direction setting in the upper edge, cross section of hard endless tube, and its quantity can be made 1 to 20.

Claims

1, a kind of endless tube inner tube of a tyre by the combination of hard endless tube (2) and rubber ring (1), is characterized in that: rubber ring (1) is fixed in the groove on the outer garden of hard endless tube (2).

2, according to the described endless tube inner tube of a tyre of claim 1, it is characterized in that: hard endless tube (2) is a reeded hollow endless tube on the outer garden face, and rubber ring (1) is the flexible rubber ring of an annular.

3, according to the described endless tube inner tube of a tyre of claim 1, it is characterized in that: be provided with reinforced rib (3) in the hollow tubular of hard endless tube (2), it is 1 to 20 that this reinforced rib edge in the cross section of hard endless tube is subjected to force direction setting, the quantity of this reinforced rib.
