Abstract
The invention relates to an inflated tyre capable of increasing tyre bead durability containing tyre tread part (1), sidewall part (2) and tyre bead part (3) composed of tyre bead core (30) and tyre bead stuffing (31). The tyre bead stuffing is composed of lower tyre bead stuffing (311) and upper tyre bead stuffing (312). The tyre body (4) is scrolled in tyre bead core. The end of the tyre body is splitted in equal space into alternate the first part (41) set between the lower tyre bead stuffing and upper tyre bead stuffing and the second part (42) set in a way of contacting to lateral surface of upper tyre bead stuffing, thereby reducing components of tyre bead part, manufacturing procedure and manufacturing cost, minimizing the shift of tyre body scrolled in tyre bead core, preventing separation in tyre bead part, and drastically increasing endurance of tyre bead part.
Description
Technical field
The present invention relates to a kind of air-inflation tyre that improves the tyre bead durability, in more detail, the air-inflation tyre that relates to a kind of following improved tyre bead durability, the carcass that this tire can make turnup be arranged on the tyre bead core moves minimum, prevent to separate, and can reduce the inscape that constitutes bead part in bead part.
Background technology
Usually, as shown in Figure 1, carcass 4 is that radially twine at the center with the bead core 30 that many strong steel silks form.Be provided with the bottom tyre bead filler 311 and the top tyre bead filler 312 that form by different two kinds or two or more rubber mutually at bead core 30 with in the space between the carcass 4 of its winding, the outside in carcass 4 ends is provided with a plurality of reinforcement materials, thereby constitutes the bead part of tire.
If tire travels under loading condition, bead part 3 crosswise movements then stretch and compression movement repeatedly as the carcass 4 of tyre framework.At this moment, be arranged on the end of the carcass 4 on bead core 30 and the tyre bead filler 31, produce the shearing stress of concentrating in winding.
This shearing stress that produces in carcass 4 ends and the durability of tire have direct relation, are the major causes in the separation of the end of carcass 4 generation.
In the past, in order to deal with the shearing stress that carcass 4 ends produce, people attempted in the end of carcass multiple reinforcement material being set, but its effect is very little, and the problem that increases greater than the problem and the manufacturing expense of required thickness of the thickness that has a carcass portion 3.
In addition, as shown in Figure 2, people have attempted end with carcass and have been embedded in technology between bottom tyre bead filler 311 and the top tyre bead filler 312, but do not obtain expected effect.
Summary of the invention
In order to solve above-mentioned existing problem, the object of the present invention is to provide a kind of air-inflation tyre that improves the tyre bead durability, its carcass that can make turnup be arranged on the tyre bead core moves minimum, prevents to produce separation in bead part, and reduces the inscape that constitutes bead part.
To achieve these goals, air-inflation tyre of the present invention comprises fetus face, sidewall portion and bead part, above-mentioned bead part is formed by bead core and tyre bead filler, above-mentioned tyre bead filler is formed by bottom tyre bead filler and top tyre bead filler, the carcass turnup is arranged on the bead core, wherein, first and the second portion for being arranged alternately uniformly-spaced cut in the end of described carcass, described first is arranged between bottom tyre bead filler and the top tyre bead filler, and described second portion is provided with according to the mode that the lateral surface with top tyre bead filler contacts.
Description of drawings

Fig. 2 is the schematic cross sectional view of existing bead part;
Fig. 3 is the schematic perspective view of the carcass of main portion of the present invention;
Fig. 4 is the schematic cross sectional view of bead part of the present invention.
The specific embodiment
Below, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In the accompanying drawing, Fig. 3 is the schematic perspective view of the carcass of air-inflation tyre main portion of the present invention, and Fig. 4 is the schematic cross sectional view of bead part of the present invention.
As shown in Figure 3 and Figure 4, pneumatic tires according to the present invention comprises: fetus face 1, sidewall portion 2 and bead part 3.Bead part 3 is formed by bead core 30 and tyre bead filler 31.Tyre bead filler 31 is formed by bottom tyre bead filler 311 and top tyre bead filler 312, and carcass 4 turnups are arranged on the bead core 30.Wherein, the end of carcass 4 is uniformly-spaced cut.The cutting part of carcass end is divided into the first 41 that is arranged between bottom tyre bead filler 311 and the top tyre bead filler 312, the second portion 42 that is provided with the mode that contacts according to the lateral surface with top tyre bead filler 312.First 41 and second portion 42 are arranged alternately.
Have in the process that the tire of the present invention of said structure travels under the state of load-carrying, stretch repeatedly and compression movement as the carcass 4 of tyre framework, move the carcass end.But, because the described first 41 of carcass is arranged between bottom tyre bead filler 311 and the top tyre bead filler 312, described second portion 42 is arranged on the outside of top tyre bead filler 312, so can disperse the shearing stress of carcass 4 ends, makes mobile the minimizing of carcass 4 ends.
By suppressing moving of carcass 4 ends like this, can reduce the unnecessary Fabrication procedure that a plurality of reinforcement materials are set in carcass 4 ends in the prior art, and the durability of tyre bead is improved.
The present invention is not limited to the foregoing description, and in the scope that technological thought of the present invention allows, the present invention can carry out diversified distortion.
According to aforesaid the present invention, it has following effect, promptly not only can reduce the inscape that constitutes bead part, reduce Fabrication procedure and manufacturing expense, and the carcass that can make turnup be arranged on the tyre bead core moves minimum, prevent to separate, improve the durability of bead part significantly in bead part.
