Description
Technical field
The present invention relates to a kind of no ladle radials.
Background technique
Radial comes out from the 1940s, due to the performance that its unique structure bring is excellent, through more than half
The development in a more centuries, tire gradually tend to meridian.Radial experienced very long and tortuous development, nowadays more next
More tend to flattening, tubeless, high speed, environmental protection and functionalization.With the development of the automobile industry, for the performance of tire
It is required that higher and higher, have many advantages, such as the small fuel-economizing of good operation performance, rolling resistance and the good full-steel radial ply of durable, wear-resistant performance
Tire becomes the main force in tire industry.But in all-steel radial tyre driving process, tyre bead portion (at rim of the mouth) is often
Breach, deformation etc. can occur, become the multiple position that tire generates disease time, research influences the performance and used life of tire.Cause
And the structure design of tyre bead portion improves the important topic for having become world's tire.
The body cord of radial radially arranges, and the carcass ply number of plies is few, and sidewall is soft, and tyre bead rigidity is insufficient,
Stress load-bearing capacity anti-greatly is poor.Therefore, it is travelled in the state of high-speed high-load, tyre bead often becomes head in tyre element and works as
It is rushed by the position destroyed.Therefore, tyre bead portion must be reinforced, but while reinforcing, and must be taken into consideration and how to make to enhance
Tyre bead and softness sidewall between have a suitable rigid transition, prevent stress from concentrating, cause tyre bead delamination, fracture or folding
It is disconnected to wait damage.
Chinese invention patent (application number：2014106505211) a kind of steel wire infantees composite members reinforced bead is disclosed
All-steel radial tyre and preparation method, it is characterized in that being improved the structure of steel wire infantees, so that steel wire infantees
The outer end point is higher than casingply anti-package endpoint, and using fitting film and unilateral encapsulated, can alleviate steel wire infantees well
The stress of distal portion is concentrated, dispersing shear stress, and prevention rim of the mouth cracking improves the security performance of tire.In addition, joint adhesive
Piece and the transition film on the sidewall symmetrical closing anti-package endpoint centered on ladle anti-package endpoint, lead to cutting for anti-package endpoint
Shearing stress is further dispersed, it is made to be not easy to split outward.Although above structure has greater advantage to tire quality is improved,
If but the tire of above structure design (8 hours) molding fetuses of per tour only have 130-140 item, while occupying tooling and product
Conversion；Production efficiency is lower.
Summary of the invention
In order to solve the above technical problems, the object of the present invention is to provide one kind under the premise of not influencing quality energy again
Improve yield without ladle radial.
To achieve the goals above, present invention employs technical solutions below：
A kind of no ladle radial, including crown, tire shoulder, casingply, liner layer, triangle rubber, belt and
Tyre bead；The tyre bead includes wire loop and wear-resisting glue；The casingply anti-package wire loop, the width of the triangle rubber are
11.5mm-13.5mm, the height of triangle rubber are 60mm-75mm, and the endpoint on the outside of the wear-resisting glue is extended to upwards close to three
The upper apex of angle glue.
Preferably：The triangle rubber uses high-strength steel bead wire framework material, and outside is adopted in triangle rubber
With big cambered structure.
Preferably：The wear-resisting glue sizing material preparation strong using bent rich performance.
The present invention carries out a large amount of indoor tests and tyre mileage test to no ladle tire, the results showed that the application of the technology reaches
The effect of Resource regeneration.This technology is to apply in tyre industry for the first time, and ladle carries out lathe test, no ladle tire after cancelling
Durable test result is enclosed than having the tyre bead of ladle is durable to improve 3h15min.In the reality for having carried out multiple batches of multipoint mode simultaneously
Journey service testing, equal massless is abnormal, is compared by tracking data, actual average mileage has reached 13.8 ten thousand kilometers of ratios after improvement
12.7 ten thousand kilometers of normal tire improve 8.7%, and the promotion of wear hardness is deep by client's favorable comment.
Of the invention can reach 180-200 item without (8 hours) molding fetuses of ladle radial tire designs per tour, improve
Production efficiency reduces the severing of tooling and product, the technical process such as calendering of cord.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
A kind of no ladle radial as shown in Figure 1, including crown, tire shoulder, casingply 2, liner layer 1, three
Angle glue 5, belt and tyre bead；The tyre bead includes wire loop 3 and wear-resisting glue 4；The 1 anti-package wire loop 4 of casingply, institute
The width for stating triangle rubber 5 is 11.5mm-13.5mm, and the height of triangle rubber 5 is 60mm-75mm, the endpoint in wear-resisting 4 outside of glue
The upper apex close to triangle rubber 5 is extended to upwards.
The triangle rubber 5 uses high-strength steel bead wire framework material, and outside is all made of big radian knot in triangle rubber 5
Structure.The wear-resisting glue 4 sizing material preparation strong using bent rich performance.
The present invention is designed without ladle in order to guarantee that the intensity at tyre rim position meets the condition that market uses, by bead part
The material of position is adjusted, and relevant component has sidewall component (i.e. wear-resisting glue) and triangle part (i.e. triangle rubber).
1, sidewall component：The size of three glue components is adjusted, reaches protection carcass endpoint position, while to tire
Side sizing material is adjusted, and enhances bent rich performance.
2, triangle part：Triangle part redesigns, and height h design is increased than former detail design, raises trunnion axis, stress
It moves up；Radian R is designed using big radian, and the gentle Inner of carcass curve is moved；Width m value Widening Design, using high-strength steel bead wire bone
Frame material.
The value such as table 1 generated without ladle radial products application of the invention：
Table 1
It should be pointed out that above embodiments are only representative examples of the invention.The present invention can also there are many deformations.It is all
Any simple modification, equivalent change and modification to the above embodiments of essence according to the present invention are considered as belonging to this
