Abstract
The inflation-free tyre without inner tube consists of outer structure and inner structure. The outer structure includes surface rubber, cord fabric, steel wire, etc. and the steel wire is coiled and combined with the cord fabric and surface rubber. The inner structure is one hollow layer and is combined via bridges to constitute one integral. The present invention also discloses the making process of the inflation-free tyre without inner tube. The inflation-free tyre without inner tube is suitable for use in bicycle, wheel chair, motorcycle, etc.
Description
Technical field
The present invention relates to a kind of inner tube free non-inflatable tyre structure, the invention still further relates to the preparation method of this inner tube free non-inflatable tyre structure in addition.
Background technology
The existing tire that is used for bicycle, motor bike etc. is used the rubber manufacturing more, has hard tire (cover tire) and soft tire (inner tube of a tyre) to be used for two kinds.This tire has good elasticity and uses characteristics such as durable.Its weak point is often to inflate, and generally just will inflate once with several days.There are some toy cars to use band tyre, exempted gas filed trouble, but its elasticity are obviously not enough, should not be used as hand cart tyre.Chinese patent CN 1026769 C announced a kind of tubeless rickshaw tyre on November 30th, 1994, and it is a tubeless tires of making load-bearing skeleton with elastic wire, and the major defect of its existence is that consistency and elasticity is inharmonious, is difficult to apply in practice.
Summary of the invention
The objective of the invention is above-mentioned deficiency, propose a kind of inner tube free non-inflatable tyre that inflation is worried, consistency and elasticity is harmonious and preparation method of this inner tube free non-inflatable tyre thereof of having exempted at prior art.
In order to realize the foregoing invention purpose, inner tube free non-inflatable tyre of the present invention is made up of external structure and inner structure, external structure comprises tread-rubber, cord, steel wire etc., coil of wire is glued together around back and cord, tread-rubber, inner structure is hollow plies, and inner structure and external structure are formed integral body by the bridge formation mode.
The manufacture method of above-mentioned inner tube free non-inflatable tyre tire of the present invention comprises the steps:
(1) sizing material of accomplishing fluently is pulled into hollow green tire pipe (inner structure is got the raw materials ready); Fixed length cuts hollow green tire pipe (inner structure moulding), forms hollow green tire circle behind the crooked joint; Hollow green tire circle is added sulphur to four to medium (semicure);
(2) get steel wire, cord and tread-rubber (external structure is got the raw materials ready) ready; The three integrated form to give birth to embryo's (external structure moulding);
(3) shaping: will give birth to the embryo and be enclosed within half-mature hollow green tire circle outside, and make it to become the tire blank;
(4) sulfuration: the tire blank after the shaping is gone into the mould sulfuration to well done, and hollow tyre bead and living embryo are integrated, and become integral body, are finished product.
With respect to prior art, inner tube free of the present invention is exempted from inflation and is had following characteristics: the external structure of (1) tire: identical with traditional airtyred tyre structure, also comprise materials such as tread-rubber, cord, steel wire, keep crushing resistance, resistance to abrasion, the whole associating property of tire carcass.(2) inner structure of tire is hollow plies, in order to replace the function of the inner tube of a tyre, very property and withstand load intensity is arranged preferably, does not need to replenish air pressure.(3) tire inner structure and external structure are formed whole by the bridge formation mode.Conventional tire after the inflation of finished product and the inner tube of a tyre is compared its load intensity and is surpassed, and because of its hollow, so have elasticity preferably again.(5) cushion characteristic is good: keep pneumatic tire structure and treat that some cushion characteristic is preferably arranged.(6) dimensional stability is good: compare with common solid tyre, dimensional stability is preferably arranged.(7) tire intensity is good: also adopted the framework material of pneumatic tyre cover, as cord, steel wire etc., had good tire intensity.(8) safety performance is good: more can not punctured the accident of meeting accident accidentally because of tire.
Description of drawings
Fig. 1 is the flow scheme that the present invention prepares air core tyre;
Fig. 2 is the schematic cross-section of air core tyre of the present invention.
Wherein, 5 is external structure; 1 is tread-rubber; 2 is cord; 3 is inner structure; 4 is steel wire.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described.
As shown in Figure 2, the inner tube free non-inflatable tyre of a preferred embodiment of the present invention is made up of external structure 5 and inner structure 3, external structure 5 comprises tread-rubber 1, cord 2 and steel wire 4 etc., steel wire 4 coiling back and cord 2, tread-rubber 1 are glued together, inner structure 3 is hollow plies, and inner structure 3 and external structure 5 are formed integral body by the bridge formation mode.
The preparation process of inner tube free non-inflatable tyre is described below in conjunction with Fig. 1:
1, pulls out hollow green tire pipe with machine earlier, (burden requirement of the visual finished product of its sicula thickness is freely adjusted), and super pressure-high temperature steam usefulness in perforating the time is advanced for sulfuration on hollow green tire tube wall, after the cooling more on request wheel footpath size fixed length cut and joint, repair surplus glue behind the joint, be placed on it is cooled off as early as possible, should the vulcanizing earlier of first joint, prevent distortion, pressure-controlled is at 10kg/cm in the sulfuration
2, external pressure is controlled at 7.5kg/cm
2, curing temperature is controlled at 120 ℃, 7 minutes time, adds sulphur to medium.
2, the processing procedure of outside green tire will pass through " external structure is got the raw materials ready " operation, get the material of making the cover tire indispensability ready: steel wire, cord and tread-rubber, by " external structure moulding " operation, utilize the offhand machine that corresponding these the three kinds of materials of specifications and models are integrated then, form and give birth to the embryo.
3, the sicula behind the semicure is put while hot outer viviparous embryo's shaping, go into the mould sulfuration then, pressure-controlled is at 11kg/cm in the sulfuration
2, the sulfuration external pressure is controlled at 9kg/cm
2, curing temperature is controlled at 140 ℃, and 10 minutes time, at this moment whole tyre vulcanization is to well done, and the sicula and the exterior tyre surface of sulfuration back inner face fuse, and become final products and exempt to inflate the hollow tire.
Claims (2)
1, a kind of inner tube free non-inflatable tyre is made up of external structure and inner structure, and inner structure and external structure are formed integral body by the bridge formation mode; It is characterized in that external structure comprises tread-rubber, cord, steel wire etc., coil of wire is glued together around back and cord, tread-rubber, and inner structure is hollow plies.Hollow plies and tread-rubber are made up of raw materials such as natural rubber, neoprene, reinforcing agent, aging inhibitor, vulcanizators.
2, a kind of method for preparing the described inner tube free non-inflatable tyre of claim 1 may further comprise the steps:
