Description
Technical field
The utility model 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 utility model patent (application number: 2014106505211) discloses a kind of steel wire infantees composite members reinforcement
The all-steel radial tyre and preparation method of tyre bead, 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 well
The stress of infantees distal portion is concentrated, dispersing shear stress, and prevention rim of the mouth cracking improves the security performance of tire.In addition, patch
Conjunction film and the transition film on the sidewall symmetrical closing anti-package endpoint centered on ladle anti-package endpoint, lead to anti-package endpoint
Shear stress further dispersed, make it be not easy to split outward.Although above structure has raising tire quality larger
Advantage, 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 purpose of the utility model is to provide one kind under the premise of not influencing quality
Can improve again yield without ladle radial.
To achieve the goals above, the utility model uses technical solution 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.
As a preferred solution: the triangle rubber uses high-strength steel bead wire framework material, and outside is adopted in triangle rubber
With big cambered structure.
As a preferred solution: the wear-resisting glue is prepared using the strong sizing material of performance is deflected.
The utility model 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
Achieve the effect that Resource regeneration.This technology is to apply in tyre industry for the first time, and ladle carries out lathe test, no steel after cancelling
Packet tyre bead durable test result is than having the tyre bead of ladle is durable to improve 3h15min.The reality of multiple batches of multipoint mode has been carried out simultaneously
Border mileage service testing, equal massless is abnormal, is compared by tracking data, and actual average mileage has reached 13.8 ten thousand public affairs after improvement
In 8.7% is improved than 12.7 ten thousand kilometers of normal tire, the promotion of wear hardness is deep by client's favorable comment.
The utility model can reach 180-200 item without (8 hours) molding fetuses of ladle radial tire designs per tour,
Production efficiency is improved, the severing of tooling and product, the technical process such as calendering of cord are reduced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
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 2 anti-package wire loop 3 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 end in wear-resisting 4 outside of glue
Point extends to the upper apex close to triangle rubber 5 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 is prepared using the strong sizing material of performance is deflected.
The utility model is designed without ladle in order to guarantee that the intensity at tyre rim position meets the condition that market uses, by tire
The material at circle 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, and reaches protection carcass endpoint position, while to tire
Side sizing material is adjusted, and enhancing deflects 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, the gentle interior shifting of carcass curve；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 utility model:
Table 1
It should be pointed out that above embodiments are only the representative examples of the utility model.The utility model can also there are many
Deformation.All essence any simple modification, equivalent change and modification to the above embodiments according to the utility model,
