Abstract
An environment protection type non-inflation polyurethane tyre is composed of the surface and hollow body of tyre, which is made up of antiwear elastic polyurethane rubber through pouring and centrifugal shaping, and the core consisting of 2-3 rubber tubes and more than two high-strength fibre cables or steel wire cables.
Description
Technical field:
The present invention relates to non-inflatable tyre, specifically a kind of environment-friendly type exempts to inflate pu tire.
Background technology:
Non-inflatable tyre is a kind of non-inflatable, safe novel tire of not being afraid of thorn, can not blowing out.
At present, though the patent of invention of numerous non-inflatable tyres is arranged both at home and abroad, but all owing to aspect technical pattern, manufactured materials and the manufacturing process of tire truly feasible innovation is not being arranged, mostly exist tire quality weight, poor flexibility, the effort of riding, power consumption is big, Nei Shengre is big, feed stock cost is high and defectives such as slip, swing, instability appear in vehicle tire in the middle of travelling, therefore be difficult to be accepted, all be difficult to so far apply by consumers in general.
Summary of the invention:
The technical matters that solves:
The purpose of this invention is to provide that a kind of later-model non-inflatable tyre---environment-friendly type exempts to inflate pu tire, it is compared with present non-inflatable tyre, have that quality is lighter, elasticity is better, it is more laborsaving to ride, power consumption is littler, Nei Shengre is little, the cost of material is low, it is more firm to combine with steel ring, it is more steady to travel, can not habitual abortion, more can not fall tire, be not afraid of thorn, excellent properties such as also can not blow out.It has solved well that the ubiquitous quality of present non-inflatable tyre is heavy, elasticity is not enough, the effort of riding, power consumption is big, Nei Shengre is big, material cost is high, it is insecure inadequately stable even tire can swing or technical matters such as slip when causing vehicle ' to combine with steel ring.
Technical scheme:
A kind of environment-friendly type of the present invention exempts to inflate pu tire, its technical characterictic is: tread of tyre and carcass be with high resilience again the liquid charging stock of the polyurethane synthetic rubber of high abrasion adopt the novel technology of making base of casting-centrifugate to make, and, in tire, be wrapped in two the various India rubber tube of bar unitized construction and two bar high strength fibre rope or steel ropes at the most at the most according to the tire of different cultivars; The India rubber tube of establishing in the described tire is two, with stacked near the intermediate vertical of tire inboard; The India rubber tube of establishing in the tire is three, and is to be " product " font structure near the tire inboard stacked; The India rubber tube of establishing in the tire is more than four, then earlier many less India rubber tubes is inserted in the bigger India rubber tube, and then it is arranged in the tire.The leftover pieces that described India rubber tube makes full use of in waste and old tire, rubber and the production are pulverized special the forming of processing; The built-in high strength fibre rope of described tire mainly is applicable to cycle tyre, children's tire, electronic tire, manpower tire, the less tire of cycle tyre equal-volume, steel rope then is applicable to fork truck tire, storage battery tire, the cycle tyre that interior diameter is little, the tire that the doughnut equal-volume is bigger, textile rope or steel rope all should be arranged on the inboard of tire sleeve in steel ring part, every tires with two at the most bar be advisable; The built-in India rubber tube of described tire is according to the tire of different cultivars, and as the tire of low speed driving, India rubber tube is hermetic, as the tire of running at high speed, and then can directly get out one to a plurality of louvres with electric drill in the both sides of its India rubber tube and carcass.
Beneficial effect:
Tread of tyre of the present invention and carcass are made with the polyurethane synthetic rubber raw material, it is compared with traditional natural rubber tire, performances such as its resistance to abrasion, elasticity, toughness, tear resistance and anti-otch growth property will be better, more excellent, its load-carrying capacity is stronger, service life is also longer; The two different India rubber tubes of bar unitized construction at the most that are provided with in the tire of each kind, tire of the present invention is compared with other non-inflatable tyre, its elasticity is better, it is more laborsaving, more comfortable to ride, power consumption is lower, near the India rubber tube of tire inboard and many high strength fibre ropes or steel rope, make tire in motion, because the effect of pressure, the India rubber tube of tire inboard will be to steel ring both sides spreading, make tire more firm, thereby solved effectively in the past that non-inflatable tyre can slide in motion, swing and cause unsettled defective with combining of steel ring; The leftover pieces that India rubber tube makes full use of in waste and old tire, rubber and the production are pulverized the special one-tenth of processing, turn waste into wealth, not only can significantly reduce the use amount of resource-constrained but also expensive urethane raw, reduce the tire cost, help environmental protection again, therefore say that tire of the present invention also belongs to the environment-friendly type tire; Tire of the present invention also can be provided with louvre in the both sides of India rubber tube and carcass according to the needs of high-speed tire kind, reduces the high temperature that vehicle produces in the tire when running at high speed effectively; In addition, excellent specific properties such as that tire of the present invention had was non-inflatable, be not afraid of thorn, can not blow out, long service life, to remove a large amount of inflations, tire patching, the expense of changing tire and quality time to the user, and the more important thing is to the user and bring great convenience and safety control.Tyre production technology of the present invention is simple, does not have " three wastes " discharging in the production process, meets very much the high standard requirement of the world today to environmental protection, can large-scale development production, apply.
Description of drawings:
Below in conjunction with accompanying drawing environment-friendly type of the present invention being exempted to inflate pu tire elaborates.
Fig. 1 is the cross-sectional structure scheme drawing that environment-friendly type of the present invention exempts to inflate the built-in two slat gum pipes of pu tire.
Fig. 2 is the cross-sectional structure scheme drawing that environment-friendly type of the present invention exempts to inflate the built-in three slat gum pipes of pu tire.
Fig. 3 is the cross-sectional structure scheme drawing that environment-friendly type of the present invention exempts to inflate built-in four the above India rubber tubes of pu tire.
The specific embodiment:
Mark among Fig. 1, Fig. 2, Fig. 3: 1-tyre surface, 2-carcass, 3-India rubber tube, 4-textile rope or steel rope, 5-louvre.
As shown in FIG., bar high strength fibre rope or steel rope are arranged in the tire-mold on the centrifugal shaper at the most to get two earlier, cycle tyre, children's tire, electronic tire, the manpower tire, the tire that the cycle tyre equal-volume is less, so that being set, the high strength fibre rope is advisable, the fork truck tire, the storage battery tire, the tire that the doughnut equal-volume is bigger is advisable so that steel rope to be set, again according to the Structural Design Requirement of different cultivars tire, with two at the most the special in advance good India rubber tube of bar be fixed in the tire-mold, closed die then, start centrifugal shaper, the polyurethane liquid raw material for preparing is injected in the centrifugal shaper according to design flow, close centrifuge and rotate switch, treat in 10-30 minute mould to open mould after the tire slaking moulding, take out tire after repairing the non-inflatable tyre finished product; As need louvre is set on tire, then directly hole to India rubber tube in the electricity consumption both sides that are drilled in carcass.
