Abstract

A solid tire is provided, which is the improvement on the general inflation-free solid tire made of rubber or expanded plastic material, or rubber outer layer and rubber or plastic expanded inner layer, namely double-layer designed inner tire; the utility model is characterized in that between the outer rubber layer and the inner rubber or plastic expanded inner layer of the solid tire is again round provided with a layer of elastic body with proper thickness so that the solid tire, when in use, can have relatively better elasticity and anti-shock capacity, and at the same time reduce material cost and lighten the weight.

Description

Band tyre

Technical field

The utility model relates to a kind of band tyre, preferable elasticity of particularly a kind of tool and shock-proof effect and traveling comfort is provided, and reduce the band tyre of material cost and expendable weight.

Background technology

Generally in order to carry or mobile article, tend on described utensil, establish with wheel as carrying or mobile article, reach can reduce described carrying or mobile utensil in loading and weight own causes and ground between friction force, and can be comparatively laborsaving when providing mobile, as on electric cycle, bicycle, hand barrow, wheelchair, perambulator or Kickboard Scooter or the like apparatus, promptly all can install with wheel so that above-mentioned effect purpose.

Yet, with regard to wheel, it is made up of wheel rim and tire, with tire at present, because of it is mostly formed to fill in having with the inner tube of a tyre of air and by the cover tire that rubber is made, be no matter cause be to be used for Regular Bicycle or hand barrow or Kickboard Scooter, even be used in particular for the electric cycle of general high age level, or the wheelchair of handicapped person's use, considering under the more inconvenient factor of described use group's action, must notice that especially just its tire inner tube should avoid blowing out or leaking gas the facts, the inconvenience that the unlikely user of causing in side can't move on smoothly, be with, with regard to tire construction in design, how overcoming and avoid the above-mentioned facts to take place, promptly is that the tire manufacturer is eager to pursue and improved place.

And then, in the streets thereby the birth of band tyre has been arranged, can must not inflate fully to reach, and again can the above-mentioned facts of blowing out of unlikely generation.

And with made inflation-free band tyre at present, it is generally adopted fully and is made with rubber or foamed plastic material, and is right in the material cost of rubber or foamed plastic is quite high, be with, if whole tire is made material cost is increased with rubber or foamed plastic fully, have much room for improvement; Secondly, because of it is to be made by rubber or foamed plastic, weight is quite heavy, also waits to improve; Add,, make the band tyre make to absorb the uneven vibrations that produce in ground, form not good or the like the disappearance of car body shock-proof effect and produce because of rubber mass lacks flexibility firmly.

See also Figure 1 and Figure 2, have promptly in the streets that to change with the skin be rubber layer 2, its internal layer is formed two-layer equation inner tube of a tyre design-calculated band tyre by rubber or plastic foamed layer 3, by described kind of two-layer equation inner tube of a tyre design, make outer layer rubber layer 2 have the effect that load high-mechanic and tire can not break, its internal layer rubber or plastic foamed layer 3, then because of make rubber (or plastics) molecule and the intermolecular formation slight gap of rubber (or plastics) make the light and tool elasticity of weight by foaming, and the band tyre that material cost is made with rubber or foamed plastic fully is low, the more above-mentioned band tyre made from rubber or foamed plastic fully, in material cost, on weight and the shock-absorbing, reach and improve effect.

Yet, above-mentionedly form two-layer equation inner tube of a tyre design-calculated band tyre by outer layer rubber layer 2 and internal layer rubber or plastic foamed layer 3, it is than the band tyre made from rubber or foamed plastic fully, improve effect though reach on material cost, weight and shock-absorbing, so its actual shock-proof effect that can improve is still limited; See also Fig. 1, Fig. 3-A, Fig. 3-B, Fig. 4-A, Fig. 4-B and shown in Figure 5, described kind by outer layer rubber layer 2, internal layer rubber or plastic foamed layer 3 are formed two-layer equation inner tube of a tyre design-calculated band tyre, be to make because of internal layer foaming layer 3 with rubber or plastics, add that it is making by foaming under rubber (or plastics) molecule and the intermolecular formation slight gap of rubber (or plastics), when it being installed and used in above-mentioned electric cycle, bicycle, hand barrow, wheelchair, on perambulator or Kickboard Scooter or the like the apparatus, when if a period of time does not use, because of described weight such as apparatus such as grade is to drop on fully on the described band tyre (as Fig. 3-A, and shown in Fig. 4-A), and the slight gap of rubber (or plastics) molecule and the intermolecular formation of rubber (or plastics) in the compressing internal layer foaming layer 3, cause and to have under the preferable elasticity as the inner tube of a tyre of inflatable tire, make outer layer rubber layer 2 bottom 21 peripheral regions of itself and 4 contact positions, ground, to be and be close to flat state and be affixed on ground 4, generation deformation and setting of a specified duration and of a specified duration, when causing described strained band tyre to desire to use once again, the described former outer layer rubber layer that contacts with ground 42 bottom 21 shapes, flat state (shown in Fig. 3-B) will be and circular arc can't be recovered to be at once, cause described band tyre further to desire to rotate when advancing, its outer peripheral edges can't rounded state (shown in Fig. 4-B) and produce the shake irregularity facts (as shown in Figure 5), haves much room for improvement.

Summary of the invention

The purpose of this utility model is to provide a kind of band tyre, makes band tyre when completing, and reaches preferable elasticity of tool and shock-absorbing, and reduces the effect of material cost and expendable weight simultaneously.

To achieve these goals, the utility model provides a kind of band tyre, adopt the band tyre of making by rubber or foamed plastic fully for inflation-free, or by outer layer rubber layer and internal layer rubber or two-layer equation inner tube of a tyre design-calculated band tyre that plastic foamed layer is formed, it is characterized in that: outer is rubber layer, its internal layer is rubber or plastic foamed layer, its outer layer rubber layer and internal layer rubber or plastic foamed interlayer, and ring is established one deck elastic body again.

Described elastic body is rubber, thermoplastic rubber or excellent power glue.
