Description
Technical field
The utility model is related to a kind of tire, belongs to tire product technical field, refers in particular to a kind of compound height of dual density
Molecular material non-inflatable tyre.
Background technology
Existing polyurethane (PU) Foamed inflation-free tire, with thoroughly anti-puncture, exempts from inflation, high intensity, light durable, bullet
Property it is moderate, from maintenance the advantages of.PU Foamed inflation-free tires are a kind of tires that need not be inflated, using micro- closed-cell foam technology
Macromolecule polymeric material is formed to not connected and fine and close micro air chamber, inside is full of the tire of high elasticity sponge body shape.
On the one hand this high polymer material foam sponge body utilizes tridimensional network and permanent restorability, be squeezed, stretch after still
Original shape can be recovered so that tire can keep shape invariance, it is on the other hand again independent mutually using countless interconnections
Micro- closed pore causes tire to possess excellent elasticity and cushion effect, and can fully bear the pressure change of tire, when making tire any
Wait and all keep enough strong, just as traditional hard-pumped state of the inner tube of a tyre, make one still as ride conventional tire it is comfortable gently
Ingeniously.Therefore, PU Foamed inflation-free tires have been increasingly becoming the main force of tire market because of its unique advantage, its market prospects
It is considerable.
But, although existing PU Foamed inflation-free tires have multiple advantages, still, and there is also following defects：It is existing
There is non-inflatable tyre to be generally single density material product, be monomer structure, shock-absorbing effect is poor, not wear-resisting, brake and ground unlubricated friction
Scouring damages obvious, and brake and ground grip are poor, and speed is higher than 10 kilometers/hour, and carcass interior molecules easily extrude life
Hot scorification pore-forming, it is on the other hand single for color, and night do not have fluorescent effect, it is not safe enough.
Utility model content
The purpose of this utility model is to overcome shortcomings and deficiencies of the prior art to be combined high score there is provided a kind of dual density
Tire body and tread ply is made using two kinds of different density materials in sub- material non-inflatable tyre, the non-inflatable tyre, is formed
Integral composite construction, efficiently solve present in prior art shock-absorbing effect difference and braking effect it is poor, it is not wear-resisting the problems such as, it is real
With reliable and secure.
To achieve these goals, the utility model is realized according to following technical scheme：
A kind of dual density composite high-molecular material non-inflatable tyre, includes tire body, and the tire body foams for PU
Body solid construction；Also include the tread ply for being arranged at all edges on the outside of tire body, the tread ply is polyurethane elastomer structure,
Density is different from tire body, and integral with tire body bonding shape.
Further, the tread ply is the texture structure of projection.
Further, the inside of the tire body is circumferentially provided with least a nylon coil or wire coil.
Further, the side position of inner ring two of the tire body is separately provided for the setting-in neck installed.
Further, the tire body and/or tread ply are filled with color fluorescence material.
Compared with prior art, its advantage is the utility model：
1st, shock-absorbing effect is good, with double-layer shock-absorbing effect, and shock-absorbing effect is close to traditional inflatable tire；
2nd, braking safe, existing PU foaming solid tyre is on concrete cement road surface, 20 kilometers/hour of speed, brake
Distance is 10 meters, and non-inflatable tyre of the present utility model is only with 1 meter, and abrasion is less than rubber tyre；
3rd, wear-resisting and not heat, tread ply of the present utility model is made up of polyurethane elastomer, and tire body is by low-density
Microporous three-dimensional structural support, two kinds of materials, two kinds of density, this two kinds of materials and structure, can effectively carry pressure hypertonic, significantly
Heat is reduced, and can quickly cross tread ply tread and is radiated rapidly, the problem of PU material high speed heats cause high heat burnout is solved,
It is more wear-resisting, it is absolutely different from skinning from existing single density polyurethane PU Foamed inflation-free tire epidermis；
4th, appearance colour is various beautiful, night fluorescence, safer.
In order to be able to apparent understanding the utility model, tool of the present utility model is elaborated below with reference to brief description of the drawings
Body embodiment.
Brief description of the drawings
Fig. 1 is positive structure schematic of the present utility model.
Fig. 2 is side structure schematic diagram of the present utility model.
Fig. 3 is the schematic cross-section in A-A directions in Fig. 1.
Embodiment
As shown in Figures 1 to 3, dual density composite high-molecular material non-inflatable tyre described in the utility model, includes tire
Body 1 and the tread ply 2 for being arranged at all edges on the outside of tire body.
Above-mentioned tire body 1 is PU foaming body solid constructions；Above-mentioned tread ply 2 is polyurethane elastomer structure, and density is not
Tire body 1 is same as, and it is integral with the bonding shape of tire body 1.
Further, the tread ply 2 is the texture structure of projection；The inside of the tire body 1 is circumferentially set
Have six nylon coils 3 (or wire coil, it is therefore an objective to ensure that tire is firmly locked wheel rim, prevents tread flaking), tire body 1 it is interior
Enclose the setting-in neck 11 that two side positions are separately provided for installing.
Further, the tire body 1 and/or tread ply 2 are filled with color fluorescence material.
The production technology of the utility model non-inflatable tyre is as described below：
