Abstract

The utility model relates to a shock attenuation solid tyre, its appearance is like the wheel shape, solid tyre includes outmost tread glue film, middle child core glue film, the basal portion glue film of inlayer from the extroversion in the cross-section, wherein tread rubber contact ground, basal portion glue contact wheel hub, child core glue film replaced by the shock attenuation area, the shock attenuation area skin is the elastic glue film, thickness 6-15mm, and the inlayer is the buffering glue film, absorbs external force, and thickness is 5-10 mm. The shock absorption performance is improved greatly than the original, the person takes comfortably, the jolt is close to the pneumatic tire, but the service life is greatly longer than that of the pneumatic tire, and the pneumatic tire has the advantages of high wear resistance, no fear of being pricked, no inflation, high load and long service life.

Description

Shock attenuation solid tyre

Technical Field

The utility model relates to a solid tyre technical field, concretely relates to shock attenuation solid tyre.

Background

The solid tire is a tire corresponding to a pneumatic tire (hollow tire), and the carcass thereof is solid, does not use a cord as a framework, does not need to be inflated, and thus does not need an inner tube or an inner liner. The solid tyre has the advantages of high wear resistance, no fear of being pricked, no inflation, high load and long service life, but also has a plurality of defects, one of which is the biggest defect that the damping performance is too poor and people feel uncomfortable in riding.

The solid tire mainly comprises three parts, namely tread rubber, tire core rubber and base rubber, wherein the base rubber is a Dutch belt with high strength and high hardness, and the Dutch belt has high hardness after vulcanization, which is a main reason for poor damping performance of the solid tire.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a high shock attenuation, riding comfort solid tyre.

The solid tire is composed of tread rubber at the outermost layer, tire core rubber in the middle and base rubber at the innermost layer, wherein the base rubber is commonly called a Dutch belt, and the hardness is higher after vulcanization, which is the main reason of poorer damping performance of the solid tire. The composite tread rubber is combined with the tire core rubber, the thickness of the composite tread rubber is reduced by 10-25% compared with that of the original tread rubber and tire core rubber, a damping belt is arranged between the tread rubber and the tire core rubber and comprises an elastic rubber layer and a buffer rubber layer, the elastic rubber layer is made of high-elasticity rubber, external force can be resisted, the elasticity is increased, the thickness is 6-15mm, the buffer layer is made of rubber absorbing external force, and the thickness is 5-10 mm.

Two steel wire belt bundle layers are transversely arranged in the middle of an inner cavity of the elastic rubber layer, a gap is reserved between the two steel wire belt bundle layers, and steel wire columns are uniformly filled in the gap between the two steel wire belt bundle layers; and the inner cavity of the base glue layer and the position close to the bottom of the inner cavity are filled with steel wire rings at equal intervals from left to right.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses the solid tyre shock attenuation performance of making improves by a wide margin more originally, and personnel take comfortablely, and the nature of jolting is close pneumatic tire, nevertheless life is greater than pneumatic tire by a wide margin, still has the high wear-resisting that pneumatic tire does not have, is not afraid of to be pricked, does not inflate, high load, long service life's advantage.

Drawings

FIG. 1 is a schematic structural view of a solid tire section according to the present invention;

in the figure: 1. a solid tire; 2. a tread rubber layer; 3. an elastic glue layer; 4. a base glue layer; 5. a bead ring; 6. a buffer glue layer; 7. a steel belt ply; 8. a steel wire column; 9. and (4) a boss.

Detailed Description

The following description and the accompanying drawings are used to explain the detailed mode of the invention.

Example 1

The utility model provides a shock attenuation solid tyre, its appearance is like the wheel shape, and solid tyre 1 includes outermost tread glue film 2, middle child heart glue film, innermost base glue 4 from the outside in the cross-section, wherein tread glue film 2 contact ground, base glue film 4 contact wheel hub, the child heart glue film replaced by the shock attenuation area, the shock attenuation area skin is elastic glue film 3, thickness 6-15mm, and the inlayer is buffering glue film 6, absorbs external force, and thickness is 5-10 mm.

Example 2

The elastic rubber layer is made of high-elasticity rubber materials, can resist external force and increase elasticity, the elastic rubber in the formula can be adopted, the buffer layer is made of soft rubber in the formula and absorbs the rubber materials of the external force, so that the elasticity can improve rebound after stress, the buffer rubber layer can absorb impact force, and the elastic rubber layer and the buffer rubber layer are used in a superposed mode, so that a good effect can be achieved.

Two layers of steel wire belt bundle layers 7 are transversely arranged in the middle of the inner cavity of the high-elasticity layer 3, a gap is reserved between the two layers of steel wire belt bundle layers 7, and steel wire columns 8 are uniformly filled in the gap. The steel wire ring 5 is filled at the bottom of the inner cavity of the base glue layer 4. The steel wire rings 5 are arranged at intervals and filled at equal intervals. The wire column 8 and the wire loop 5 may serve as reinforcement.

Example 3

Different from the embodiment 2, the side wall of the solid tyre is respectively provided with 2 circles of bosses 9 which are positioned at the splicing positions of the tread rubber and the shock absorption belt and the splicing position of the shock absorption belt and the base rubber. Thus, the spliced position is reinforced. And the integral rigidity of the solid tire is enhanced.

Claims

1. The damping solid tire is in a wheel shape, and comprises an outermost tread rubber layer and an innermost base rubber layer in cross section, wherein tread rubber is in contact with the ground, and the base rubber is in contact with a wheel hub.

2. The shock-absorbing solid tire according to claim 1, wherein two steel belt layers are transversely arranged in the middle of the inner cavity of the elastic rubber layer, a gap is reserved between the two steel belt layers, and steel wire columns are uniformly filled in the gap.

3. The shock absorbing solid tire of claim 1, wherein the position of the bottom of the inner cavity of the base rubber layer is filled with a bead ring.

4. The shock absorbing solid tire of claim 3 wherein said bead rings are spaced apart and filled equidistantly.

5. The shock absorbing solid tire of claim 1, wherein the solid tire has 2 rings of bosses on each sidewall at the positions of the tread rubber layer, the splicing position of the shock absorbing belt and the base rubber layer.
