Description
Technical field
The present invention relates to a kind of cross-country type rainforest tire, in particular a kind of single steel wire winding
Cross-country type rainforest tire.
Background technology
Along with expanding economy, the living standard of the people gradually steps up, and cross-country sports will be by increasingly
Many people must like, off-the-highway tire will become main flow, and tire is the safety member on automobile, tire
Safety is by particularly important, and the safety how improving tire will become company's important topic.
Hydraulic bursting test is the important tests of inspection tire safety, in present domestic tire enterprise
, tire bead steel wire shaping mode many employings root row's canoe, this canoe maximum
Shortcoming is exactly that steel wire breaking tenacity utilization rate is low, and the most only the 50% of steel wire breaking tenacity, causes material
Waste, the anti-burst ability of tire is relatively low.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of single steel wire winding is cross-country
Type rainforest tire.
The present invention is achieved by the following technical solutions, and the present invention includes tyre surface, liner, casing ply
And tyre bead, described liner is arch, and casing ply is coated on outside liner, and tyre bead twines for single steel wire
Turning to, tyre surface is positioned at the top of casing ply；Described casing ply is polyester cord, described tire
Being preced with wide and that section is wide ratio is 110～120%.
One of optimal way as the present invention, described arch is three sections of circular arc compositions, three sections of circles
The radius ratio of arc is 20:4:3.
Described tyre surface includes shoulder portion and center running lug, and described shoulder region is in the two of center running lug
Side, and shoulder portion is provided with unidirectional tire tooth, the height of unidirectional tire tooth is 25～35mm.Tire
The unidirectional tire tooth of each piece of shoulder is just as the least excavator, using the teaching of the invention it is possible to provide powerful earth-grasping force
, no matter on the most severe road, tire can catch ground inflexibly, provides strong for automobile
Big earth-grasping force.
The central authorities being arranged on tyre surface that described center running lug protrudes.Use wide tread design theory, increase
Its contact area big, the protrusion design of tread cap central authorities decorative pattern, strengthen tire muddy wet
Skid resistance on road surface, ground.
Described tyre surface is provided with the first projection, and the first projection is provided with the second projection.Make on the first projection
Earth and stone be easy to be thrown out of or eject, strengthen tire self-cleaning property, it is to avoid at mud
Slipping in ground.
For reaching more preferable self-cleaning performance, the area ratio of described first projection and the second projection is 9:1,
Aspect ratio is 3:1.
The present invention has the advantage that the present invention uses single steel wire winding technology compared to existing technology,
In the case of using the most less identical steel bead wire, wheel amniotic fluid quick-fried performance is greatly improved
, tire blow-out that tire in a situation of use due to rim of the mouth fracture cause is reduced or eliminated, subtracts
Even if less or eliminate tire blasting phenomena of tire under improper inflation situation；Elimination steel ring connects
The stress of too much excessive generation is concentrated；Improving the breaking tenacity utilization rate of wire loop, steel wire is pulled apart
Power utilization rate reaches more than 97%.The Internal periphery of tire, just as an arch bridge, can make stress uniformly divide
Cloth, to each position of tire, reduces the deformation probability of tire.Higher hat width and section width it
Ratio, it is provided that bigger contact area and the earth-grasping force of tire.Owing to being preced with wide increasing,
Tyre surface both sides use the design of unidirectional exaggeration tire tooth, and tire can be made to play very well at rainforest landforms
Earth-grasping force and driving force, use the tire tooth of narrow sidewall width tyre surface and exaggeration to design, it is also possible to protection
Tire sidewall, it is to avoid sidewall is by sharp-pointed stone incised wound or puncture.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of tyre surface.
Detailed description of the invention
Elaborating embodiments of the invention below, the present embodiment with technical solution of the present invention is being
Implement under premise, give detailed embodiment and concrete operating process, but this
Bright protection domain is not limited to following embodiment.
As it is shown in figure 1, the present embodiment includes tyre surface 1, liner 2, casing ply 3 and tyre bead 4, described liner
2 is arch, and casing ply 3 is coated on outside liner 2, and tyre bead 4 is made for single steel wire winding, tyre surface
1 top being positioned at casing ply 3；Described casing ply 3 is polyester cord, and the hat width of described tire is with disconnected
The ratio of face width is 110～120%.The arch of the present embodiment is three sections of circular arc compositions, three sections of circular arcs
Radius ratio is 20:4:3.
Single steel wire winding technology, the steel wire radical of use is also considerably reduced, and the glue amount of covering of steel wire reduces 50
%, so can reduce by a relatively large margin and use the rubber pollution to environment, the breaking tenacity profit of steel wire
Also being greatly improved by rate, the steel wire utilization rate of single steel wire is the most all more than 97%, and root row is wound around
At most about 70%, along with the utilization rate increasing steel wire of tire used air pressure is gradually lowered,
Using radical is that in the case of root row is wound around half, the hydraulic pressure demolition value of single steel wire winding is appointed far away
More than root, row is wound around.Root row winding can bottom wire loop, stay next row joint, this like
Edge of a knife cutter upwards the most sidewards when of tire rolling, wire loop is very
Easily rupturing at this, main cause is that stress concentrates on this, causes steel wire fracture, single steel wire to twine
It is wound on wire loop and would not leave joint, each position uniform stressed of wire loop, wire loop
Tensile strength is greatly improved.
As in figure 2 it is shown, tyre surface 1 includes that shoulder portion 11 and center running lug 12, described shoulder portion 11 are positioned at
The both sides of center running lug 12, and shoulder portion 11 is provided with unidirectional tire tooth 111, unidirectional tire tooth 111
Height be 25～35mm.The unidirectional tire tooth 111 of each piece of tire shoulder digs just as the least
Pick machine, using the teaching of the invention it is possible to provide powerful earth-grasping force, no matter on the most severe road, tire can be dead
Ground is caught at fatal position, provides powerful earth-grasping force for automobile.
The central authorities being arranged on tyre surface 1 that described center running lug 12 protrudes.Use wide tyre surface 1 design concept
, increase its contact area, the protrusion design of tyre surface 1 bizet central authorities decorative pattern, strengthen tire muddy
Wetland road surface on skid resistance.
Described tyre surface 1 is provided with the first projection 13, and the first projection 13 is provided with the second projection 131.First
The area ratio of projection 13 and the second projection 131 is 9:1, and aspect ratio is 3:1, makes in the first projection 13
Earth and stone be easy to be thrown out of or eject, strengthen tire self-cleaning property, it is to avoid at mud
Slipping in ground.
