Further plastics are placed between tyre surface and support construction, plastic layer changes in 1-30mm.Tire Specification is different, and the peak load born is also different;The rigidity of material is mainly related with sectional area simultaneously, if the width of plastic layer In the case that degree is certain, the size of thickness determines that its rigidity, the size of rigidity directly determine the power (flexing resistance that material is born Can).In conclusion the length and width of load and ground connection that tire is born directly determines the thickness of plastic layer.The present invention The bigger variation of tire size, load variations being related to, therefore plastic layer is scheduled on 1-30mm.

Support construction is located between plastic layer and tire heel, is arcuate structure, circumferentially evenly distributed along tire, several altogether in circumferential direction Ten similar support constructions.

Further, the non-inflatable tyre is to exempt from inflatable load-carrying tire, bicycle tyre or card passenger tyre.

The tire heel (4) is hard rubber, blocks wheel rim, makes that opposite sliding does not occur when tire running with wheel rim;It is described Support construction (3) uses a kind of endurance sizing material, provides support, and ensure the comfort property of tire;Support construction has two sides The performance requirement in face, one, fatigue performance to get well, two, dynamic heat build up it is low.Low speed tire can select Polyurethane, can also select rubber Glue;The above tire of middling speed, generally selects rubber;Because the dynamic heat build up of rubber is relatively low.The plastic layer (2) is one layer and bullet Property body co-vulcanization thermosetting plastics, it be to cure the material synchronous with the vulcanization of rubber to have higher intensity and toughness, plastic layer , such as:HIPS (high impact polystyrene);The tire tread (1) be elastomer, have low rolling resistance, height it is wet and slippery and Good wear-resisting property.

Compared with prior art, the present invention has excellent technique effect as follows to the present invention:

A kind of novel elastomer-plastic composite of the present invention exempts from inflatable load-carrying tire, in tyre surface and support construction Between arrange one layer of plastic layer, due to plastic layer have enough intensity and toughness, excellent bending stiffness can be in radial side Enough supports are provided upwards.When carrying, plastic layer is deformed with support construction, provides support, is main load bearing component, Plastic layer can be evenly dispersed in the non-homogeneous stress generated at tyre surface by support construction, to the earth contact pressure for making tyre surface generate Power is uniformly distributed that ground connection distribution is made to become uniform, and class non-inflatable tyre is supported not connect circumferentially because of support construction when solving carrying The problems such as tread pressure mutation caused by continuous, tyre surface centre generate " warpage ", tyre surface inordinate wear, exempts to fill to improve The ground connection performance of air filled tyre, the service life of handling, driving safety and tire.
