Description

A kind of casting type polyurethane material non-inflatable tyre
Technical field
The present invention relates to tire product technical field, specially a kind of casting type polyurethane material non-inflatable tyre.
Background technique
Tire often uses under complicated and exacting terms, it subjects various modifications, load, power and height in motion Cold service, it is therefore necessary to load-carrying properties with higher, hauling ability, cushion performance, meanwhile, also require have high-wearing feature And flexible resistance and low rolling resistance and heat generation, the half that the world consumes rubber mass are used for tire production, it is seen that tire The ability for consuming rubber is not insignificant.
Existing polyurethane (PU) Foamed inflation-free tire, have thoroughly it is anti-pierce through, exempt from inflation, elasticity it is moderate, from maintenance The advantages that, PU Foamed inflation-free tire is formed macromolecule polymeric material using micro- closed-cell foam technology not connected and thin Close micro air chamber, inside are full of the tire of high elasticity sponge body shape, on the one hand this high molecular material foam sponge body utilizes Tridimensional network and permanent restorability, can still restore original shape, tire is allowed to keep shape after being squeezed, stretching Constant, on the other hand using countless interconnections, independent micro- closed pore makes tire possess excellent elasticity and buffering mutually again Power, and the pressure change of tire can be sufficiently born, allow tire whenever all to keep enough strong.
Therefore, PU Foamed inflation-free tire has been increasingly becoming the new life of low-speed vehicle tire market because of its unique advantage Power, market prospects are vast, and existing PU Foamed inflation-free tire has the advantages that multiple, and still, there is also following defects: existing Having non-inflatable tyre is the product that a kind of material is constituted, and is monomer structure, and shock-absorbing effect is poor, not wear-resisting, brake and ground unlubricated friction Scouring damage is obvious, and it is poor with ground grip to brake, on the other hand single for color, and night does not have reflective or fluorescent effect, safety It is not good enough.
Summary of the invention
The purpose of the present invention is to provide a kind of casting type polyurethane material non-inflatable tyres, to solve above-mentioned background technique The existing existing non-inflatable tyre proposed is the product that a kind of material is constituted, and is monomer structure, and shock-absorbing effect is poor, not wear-resisting, Brake it is obvious with ground dry friction and wear, brake it is poor with ground grip, it is on the other hand single for color, and night do not have it is reflective or Fluorescent effect, the problem that safety is not good enough.
To achieve the above object, the invention provides the following technical scheme: a kind of casting type polyurethane material non-inflatable tyre, It is combined by the polyurethane material of two kinds of different structures, different hardness, including tire body (1) and heavy hole (3), the tire The side of ontology (1) is provided with crown layer (2), and crown layer (2) casting is placed in the outside top week edge of tire body (1), The crown layer (2) is set to the outside of tire body (1), and the heavy hole (3) is set to the outside of crown layer (2), the wheel Tire ontology (1) is provided with wire coil (4) far from the side of heavy hole (3), and the wire coil (4) is set to tire body (1) Inside, the crown layer (2) and tread groove (5) are located at the same side of tire body (1), the tread groove (5) It is set side by side with crown layer (2), the tire body (1) is provided with wheel rim mounting ring far from the side of tread groove (5) (6), it is structure as a whole between the wheel rim mounting ring (6) and tire body (1).
Further, the tire body (1) is polyurethane (PU) microporous foaming elastomer, and tire body (1) is micro- Not connected and fine and closely woven micro air chamber is organized in hole, and high elasticity sponge body shape structure is full of inside tire body (1).
Further, the tire body (1) and crown layer (2) bonding form an overall structure.
Further, the crown layer (2) be do not foam, the polyurethane of theoretical density (or CPU) elastomeric material, and crown Layer (2) is different from tire body (1) material institutional framework, and crown layer (2) occupies 1/3 to 1/4 area of tire top layer cross section.
Further, tire body (1) two sidewalls (facade) inlay by the consistent heavy hole (3) of numerous shape or Variform heavy hole (3) unbroken composition, and the heavy hole (3) of tire body (1) two sides is mutually not through and tire body (1) The heavy hole (3) of two sidewalls (facade) can be symmetrically arranged or asymmetric distribution.
Further, the section of the wire coil (4) is circular ring structure, and wire coil (4) is about tire body (1) Middle line it is symmetrical, and every 3 tire bodies (1) be one group be provided with two groups altogether.
Further, the thickness of the tread groove (5) is less than the overall thickness of tire body (1).
Further, the wheel rim mounting ring (6) is indent circular ring structure, and the radius of wheel rim mounting ring (6) is greater than wheel The radius of tire ontology (1).
Further, a kind of forward and backward tire-mold that is independently cast in of polyurethane non-inflatable tyre production technology point enters At material mouth, raw material is rapidly feeding by mold inner-cavity by mold centrifugal force.
Compared with prior art, the beneficial effects of the present invention are:
1. foaming body and tire body foaming body do not form integral structure to crown in casting process, keep crown rolling resistance small, The tire drag very little is ridden laborsaving, easily convenient for riding.
2. the crown layer be do not foam, the polyurethane of theoretical density (or CPU) elastomeric material, the crown of tire and tire sheet Body material institutional framework is different, occupies 1/3 to 1/4 area of tire top layer cross section, and crown not foaming body and tire body foaming body Be automatically synthesized in casting process one whole, be never layered, thus reach small wear-resisting crown, on-slip, rolling resistance, hydrolysis, Acidproof, alkaline-resisting, tire body foaming sponge layer effect reaches damping effect, and shock-absorbing effect is significant, has double-layer shock-absorbing effect, inhales Effect is shaken close to traditional inflatable tire.
3. braking safe, strong with ground grip, more more effective than the brake of existing pu tire.
4. the tread ply of the non-inflatable tyre is made of the elastomer that polyurethane does not foam, tire body is by microporous foam three Structural support is tieed up, two kinds of unlike material crown hardness are high, and tire body hardness Design is low, and two kinds of materials and structure can effectively be held Compression shock and flexible is carried, heat effect is substantially reduced, it is wear-resisting and be not easy heat to reach more wear resistant, exempt from existing foaming Pneumatic tire epidermis it is absolutely different from skinning.
5. tire two sidewalls (facade) is inlayed by the consistent heavy hole of numerous shape or variform heavy unbroken group of hole At the heavy hole of tire two sides is mutually not through the heavy hole of tire two sidewalls (facade) can be symmetrically arranged or asymmetric distribution, purpose Reach not only beautiful, but also save material, reduces cost.
6. by prefabricated polyurethane (or CPU), foaming elastomer raw material A component does not add crosslinking agent, catalyst, color agent separately Deng, adjustable crown layer color makes crown layer that can be adjusted to any color before manufacture, and color is not single, colorful multiplicity, and There is reflective or fluorescent effect at night, and security performance increases.
7. tire body and crown layer is made using two different institutional framework materials in the non-inflatable tyre, one is formed Composite construction, have dual function, efficiently solve shock-absorbing effect difference existing in the prior art and braking effect it is poor, intolerant to Mill, the problems such as damping is unobvious, it is practical reliable and secure.
