Description
Technical field
The utility model belongs to band tyre technical field, is specifically related to a kind of press-fit polyurethane solid tyre for low-speed heave-load vehicle.
Background technology
Current the used tire of low-speed heave-load vehicle have solid, also have inflation.The anti-puncture of air-inflation tyre, anti-ability of isolating, service life is short and have uncertainty.The band tyre used at present, by the limitation of its manufacturing process, cannot obtain louvre by processing, in tire, heat-dissipating cannot be discharged in time, has influence on the stable of tire primary characteristic; And along with gathering of heat, all there is remarkable decline in the rigidity of tire, resistance to abrasion, anti tear, anti-cutting property, the phenomenon of also there will be slipping ring, even blowing out, jeopardizes safety simultaneously.
Utility model content
The purpose of this utility model is to overcome the shortcoming that exists in prior art with not enough, provides a kind of press-fit polyurethane solid tyre for low-speed heave-load vehicle.This band tyre perfect heat-dissipating, wear-resisting, resistance to puncture and anti-cutting property are excellent, durable in use.
The purpose of this utility model is achieved through the following technical solutions:
A kind of press-fit polyurethane solid tyre for low-speed heave-load vehicle, comprise polyurethane elastomer cover tire, be coated on the polyurethane elastomer inner tube of a tyre of polyurethane elastomer cover tire inside, between the described polyurethane elastomer inner tube of a tyre and polyurethane elastomer cover tire, be provided with wire net; The shore hardness of described polyurethane elastomer cover tire is greater than the shore hardness of the described polyurethane elastomer inner tube of a tyre.
Preferably, described polyurethane elastomer inner tube of a tyre two sides are evenly equipped with thermal vias along its axis circumference, this thermal vias and the described polyurethane elastomer inner tube of a tyre are integrated moulding by casting.
Preferably, described louvre is oval, circular or square.。
Preferably, described wire net is wrapped on the external cylindrical surface of the described polyurethane elastomer inner tube of a tyre.
Preferably, the excircle of the described polyurethane elastomer inner tube of a tyre is evenly equipped with installation gap along its axis circumference, the inner peripheral surface of described polyurethane elastomer cover tire is provided with cooperatively interact with described installation gap coordinate projection.Installation gap and coordinate projection to cooperatively interact installation, makes to have better integraty between polyurethane elastomer cover tire and the polyurethane elastomer inner tube of a tyre, prevents from mutually sliding during work.
Preferably, the cylindrical of described polyurethane elastomer cover tire is provided with gripping pattern.
The utility model has following advantage and effect relative to prior art: the utility model is by arranging several for discharging the louvre of heat-dissipating amount in polyurethane elastomer tire in polyurethane elastomer inner tube of a tyre two sides, the shape of louvre, size and number all depending on tire size change and change, the heat that inside tires is produced can be discharged smoothly in time, be conducive to keeping the original characteristic of material, avoid slipping ring, blow out, the increase etc. of energy consumption, improve service life and the safety of tire, the elasticity of tire can be improved again simultaneously, improve the traveling comfort driven.By the laying of wire net, effectively raise the structural strength of tire, thus effectively raise the ability of tire shock resistance, anti-cutting.

Description of reference numerals:
10, polyurethane elastomer cover tire, 20, the polyurethane elastomer inner tube of a tyre, 30, thermal vias, 40, wire net.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
Refer to Fig. 1 to 2, for the press-fit polyurethane solid tyre of low-speed heave-load vehicle, comprise polyurethane elastomer cover tire 10, be coated on the polyurethane elastomer inner tube of a tyre 20 of polyurethane elastomer cover tire 10 inside, between the described polyurethane elastomer inner tube of a tyre 20 and polyurethane elastomer cover tire 10, be provided with wire net 40.The shore hardness of described polyurethane elastomer cover tire 10 is greater than the shore hardness of the described polyurethane elastomer inner tube of a tyre 20.By utilizing the pouring technology of polyurethane, make the parcel completely of polyurethane elastomer cover tire 10 pairs of polyurethane elastomer inner tubes of a tyre 20 and wire net 40.
In the present embodiment, the described polyurethane elastomer inner tube of a tyre 20 two sides are evenly equipped with thermal vias 30 along its axis circumference, this thermal vias 30 is integrated moulding by casting with the described polyurethane elastomer inner tube of a tyre 20.
The polyurethane elastomer inner tube of a tyre 20 and polyurethane elastomer cover tire 10 realize the completely coated of polyurethane elastomer cover tire 10 pairs of polyurethane elastomer inner tubes of a tyre 20 and wire net 40 by the liquid form of casting type polyurethane material, form the louvre along the polyurethane elastomer inner tube of a tyre 20 two sides array by the liquid form of casting type polyurethane material.The shape of louvre, size and number all depending on polyurethane solid tyre specification change and change.
Described louvre is oval, circular or square.Described wire net 40 is wrapped on the external cylindrical surface of the described polyurethane elastomer inner tube of a tyre 20.This polyurethane elastomer inner tube of a tyre 20 is also provided with the bolt hole mutually installed with wheel rim.
The excircle of the described polyurethane elastomer inner tube of a tyre 20 is evenly equipped with installation gap along its axis circumference, the inner peripheral surface of described polyurethane elastomer cover tire 10 is provided with cooperatively interact with described installation gap coordinate projection.Installation gap and coordinate projection to cooperatively interact installation, makes to have better integraty between polyurethane elastomer cover tire 10 and the polyurethane elastomer inner tube of a tyre 20, prevents from mutually sliding during work.The cylindrical of described polyurethane elastomer cover tire 10 is provided with gripping pattern.
The present embodiment is by arranging several for discharging the louvre of heat-dissipating amount in polyurethane elastomer tire in the polyurethane elastomer inner tube of a tyre 20 two sides, the shape of louvre, size and number all depending on tire size change and change, the heat that inside tires is produced can be discharged smoothly in time, be conducive to keeping the original characteristic of material, avoid slipping ring, blow out, the increase etc. of energy consumption, improve service life and the safety of tire, the elasticity of tire can be improved again simultaneously, improve the traveling comfort driven.By the laying of wire net 40, effectively raise the structural strength of tire, thus effectively raise the ability of tire shock resistance, anti-cutting.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
