Abstract
The aim of the invention is to provide an inflatable tire, namely crazing of the tire body rolling end is prevented by arranging a crazing generation preventing mechanism at the end of the tire body which covers the tire bead cloth thereby that the tire bead part will not come in for damnification and the durability of the tire bead part can be improved as a result.
Description
Technical field
The present invention relates to improve the vehicle tyre of bead part durability.Be about following air-inflation tyre in detail, it is provided with and prevents be full of cracks mechanism and prevent from the carcass edge part crack performance that caused by shearing force to take place by roll the end at the carcass of airtyred bead part, and its result can improve the durability of bead part.
Background technology
The bead part of vehicle tyre is the part that tire contacts with wheel rim, is the tension force that supports by the tire layer of cloth that interior pressure produced, and directly transmits the part from propulsive effort, braking force and the steering effort of vehicle.The front end that has carcass on this bead part, the front end of carcass is owing to the strong motion of above-mentioned institute produces shearing force.And consequently, this shearing force chaps the carcass edge part, and its result causes the damage of bead part.
In order to protect bead part to avoid to be subjected to the effect of this shearing force, roll the end at carcass the tire infantees was set in the past, but just take these methods can not prevent that above-mentioned be full of cracks from taking place.
Summary of the invention
The present invention carries out the research with keen determination of repetition in order to solve in the past problem points, the result is clear and definite, as long as rolling the end at the carcass that covers bead part is provided with and can prevents the mechanism that chaps, then can prevent generation by the be full of cracks that shearing force caused that produces from the such power of propulsive effort, braking force and the steering effort of vehicle, its result can prevent the damage of bead part, so that finish the present invention.
Therefore, the object of the invention is the air-inflation tyre that provides following, promptly rolls the end at the carcass that covers bead part and is provided with and prevents the durability that bead part improves in be full of cracks mechanism.
Description of drawings
Fig. 1 is the amplification view of the airtyred bead part of the present invention.
Fig. 2 is the cutaway view of a plurality of concrete examples that prevents be full of cracks mechanism that is arranged at the bead part of charge of air tire of the present invention.
The specific embodiment
Below, with the present invention will be described in more detail in conjunction with the accompanying drawings.
Among the present invention, in the accompanying drawings, Fig. 1 is the amplification view of the airtyred bead part of the present invention, and Fig. 2 is the cutaway view of various concrete examples that prevents be full of cracks mechanism that is arranged at the bead part of the charge of air tire among Fig. 1.
As shown in Figure 1, air-inflation tyre of the present invention comprises: tyre surface and sidewall and bead part, and with regard to above-mentioned bead part, carcass 3 covers tyre bead heart yearn 1 and bead filler 2, arranged outside at above-mentioned carcass 3 has chafer 4, is provided with raised line (Hump strip in its lower end; 5).The invention is characterized in, in this air-inflation tyre, roll the end at the carcass of carcass 3 and be provided with the next anti-locking mechanism of be full of cracks that is used as of extremity piece 6 (edge cup).
Particularly, extremity piece 6 of the present invention is as shown in circular dashed line among Fig. 1 is amplified, owing to be the structure that between itself and carcass 3 ends, has spatial portion, so the rolling the end and can not fetter extremity piece 6 of carcass 3.
Other then can be made into any form so long as can obtain effect of the present invention, but preferably, have such structure, and promptly this extremity piece 6 itself can not apply and not have yet the structure that other shearing forces apply bead part to bead part.
Like this, the air-inflation tyre that has extremity piece in the carcass end of the present invention can prevent that carcass from rolling the end and chapping by preventing be full of cracks mechanism, alleviates the damage of bead part, consequently has the advantage that can improve the bead part durability.
Claims (5)
1. air-inflation tyre that improves the durability of bead part, comprise tyre surface and sidewall and bead part, above-mentioned bead part is to cover tyre bead heart yearn and bead filler with carcass, arranged outside at above-mentioned carcass has chafer, be provided with raised line in its lower end, it is characterized in that, be provided with the mechanism that can prevent be full of cracks in the end of rolling of above-mentioned carcass.
2. the air-inflation tyre of the durability of the raising bead part of putting down in writing according to claim 1 is characterized in that, above-mentioned prevent be full of cracks mechanism and carcass roll and be formed with spatial portion between the end.
3. improve the air-inflation tyre of the durability of the bead part of putting down in writing according to claim 1 or 2, it is characterized in that, the above-mentioned be full of cracks mechanism that prevents will form porose metal sheet bending and cover its surface and formation with rubber.
4. the air-inflation tyre of the durability of the raising bead part of being put down in writing according to claim 1 or 2 is characterized in that, the above-mentioned be full of cracks mechanism that prevents constitutes the structure that can not apply shearing force to above-mentioned bead part.
5. the air-inflation tyre of the durability of the raising bead part of being put down in writing according to claim 1 or 2 is characterized in that the section of extremity piece is pocket-shape.
