Abstract

Provided is a super-bearing vibration-suppressing engineering tire. The engineering tire is used for solving the problem of poor elasticity of existing engineering tires. Seen from the cross section, the engineering tire comprises a rubber layer, a polyurethane layer and a sponge inner core which are arranged from inside to outside in order and the elasticities thereof are increasing in order. The cross section of the polyurethane layer is O-shaped. The cross section of the sponge inner core is T-shaped. The existence of the sponge inner core can reduce the usage amount of polyurethane effectively, and reduce the whole mass of the tire, and the cost is saved. The sponge inner core has good vibration-suppressing effects, and the vibration-suppressing effects are raised greatly when the tire is compared to normal polyurethane solid tires.

Description

A kind of super carrying shock-absorption engineering tire

Technical field

The present invention relates to band tyre technical field, specifically a kind of super carrying shock-absorption engineering tire.

Background technology

In engineering machinery vehicle, widely used band tyre generally comprises polyurethane solid tyre and poly-urethane rubber compound solid tire.Band tyre has unique advantage, for example: puncture resistance, resistance toly tear, without inflation and the feature of using long service life.But also have its shortcoming, main manifestations is: its cushion characteristic is poor, elasticity is not enough, the goods of fragile vehicle and loading, and fragile road surface and kinetic equation loss large.

Summary of the invention

The object of the present invention is to provide a kind of super carrying shock-absorption engineering tire, is first a kind of large carrying band tyre, and makes it to have the not available damping performance of common band tyre by structure of modification.

The present invention solves the technical scheme that its technical matters takes: a kind of super carrying shock-absorption engineering tire, integral body is annular arrangement tire, it is characterized in that, from section, comprise from the rubber layer setting gradually outside to inside and elasticity increases successively, layer of polyurethane and inner sponge cores, and the section of described layer of polyurethane is O type, described inner sponge cores section is T-shaped, the existence of inner sponge cores can actv. reduces the use amount of polyurethane, alleviate the weight of tire integral body, save cost, inner sponge cores has good damping effect simultaneously, damping effect than common polyurethane solid tyre improves greatly.

The crown of described tire, sidewall thickening design.

In the two sides of described rubber layer, be provided with anti-side and draw projection, the whole anti-scratch performance of reinforced tire.

The invention has the beneficial effects as follows: the present invention is by being designed to traditional band tyre on three of interior China and foreign countries layer, take full advantage of outer field superhard, wear-resisting and anti-scratch performance, inner base is polyurethane material, inner core material is T-shaped sponge weighting material, the elastic performance of assurance tire integral body that can great achievement, and can form actv. damping effect in actual use procedure.There is the damping performance that general band tyre does not have, improve traveling comfort and the stability of vehicle carrying.Can be widely used in the fields such as tractor-trailer on various industrial vehicles, military vehicle, vehicle for construction, airport, harbour.

Accompanying drawing explanation

Fig. 1 is sectional schematic diagram of the present invention;

Fig. 2 is the sectional schematic diagram of embodiment bis-;

In figure: 1 rubber layer, 2 layer of polyurethane, 3 inner sponge cores, 4 grab ground decorative pattern projection, and 5 anti-sides are drawn projection.

The specific embodiment

Embodiment mono-, as shown in Figure 1,

A carrying shock-absorption engineering tire, integral body is annular arrangement tire.From section, comprise from the rubber layer 1, layer of polyurethane 2 and the inner sponge cores 3 that set gradually outside to inside and elasticity increases successively.

Wherein rubber layer 1 thickness is thicker, can improve wear resisting property and load-carrying capacity, is provided with grabs ground decorative pattern projection 4 at rubber layer 1 with ground on the ring surface contacting, and in rubber layer, according to tire standard, and at crown, position, sidewall, thicken and strengthens designing.

The layer of polyurethane 2 that a nested section is O type in rubber layer 1.Utilized polyurethane tensile strength high herein, peel strength is high, shock resistance, and rebound resilience is good, and resistance to ag(e)ing is good, and shock-absorbing performance is good, water-fast and acid-proof alkaline good, and bearing load ability is large, the advantage of long service life.

And inner sponge cores 3 sections are T-shaped, by the mode of injecting, at layer of polyurethane, form a ring-type, as a kind of weighting material, exist, there is the feature of lighter weight.

The existence of above-mentioned three layers has utilized advantage and performance characteristics separately, mutually combines and affects, and can produce the effect of super carrying, wear-resisting, anti-scratch, damping and lighter weight.

Embodiment bis-, as Fig. 2, are with embodiment mono-difference, and rubber layer has adopted thickening design, and in the two sides of rubber layer, are provided with anti-side and draw projection 5, and the whole anti-scratch performance of reinforced tire, can avoid the scuffing from the sharp object of side.

Except the technical characterictic described in specification sheets, be the known technology of those skilled in the art.

Claims

1. one kind surpasses carrying shock-absorption engineering tire, integral body is annular arrangement tire, it is characterized in that, from section, comprise from the rubber layer, filling polyurethane layer and the inner sponge cores that set gradually outside to inside and elasticity increases successively, and the section of described layer of polyurethane is O type, described inner sponge cores section is T-shaped.

2. a kind of super carrying shock-absorption engineering tire according to claim 1, is characterized in that, the crown of described tire, sidewall thickening design.

3. a kind of super carrying shock-absorption engineering tire according to claim 1 and 2, is characterized in that, is provided with anti-side draws projection in the two sides of described rubber layer.
