Abstract

The invention provides an anti-burst pneumatic tyre containing tyre tread part (1), sidewall part (2) and tyre bead part (3). The tyre body (4) is set across the tyre tread part, sidewall part and tyre bead part. The reinforcing rubber (5) is set inside of sidewall part. The tyre bead part is composed of tyre bead core (30) twined by multiple steelwires and tyre bead stuffing (31) set in the top of the tyre bead core. Wherein the tyre bead stuffing contain the first tyre bead stuffing (311) set above the tyre bead core; the second tyre bead stuffing (312) set outside of the first tyre bead stuffing and in the top of tyre flange (61); the third tyre bead stuffing (313) set above the second tyre bead stuffing, thereby preventing tyre bead separating from the rim, preventing big accidents and preventing riding comfort decreasing caused by the increase of sidewall part's rigidity.

Description

The air-inflation tyre of anti-explosion
Technical field
The present invention relates to the rigidity of sidewall portion is strengthened and the air-inflation tyre of the anti-explosion that also can travel with certain speed when the tyre break.In more detail, the air-inflation tyre of anti-explosion involved in the present invention improves the structure of tyre bead filler, can prevent the comfort decline phenomenon by bus that the rigidity increase because of sidewall portion causes thus, when sharply turning, can prevent that tyre bead breaks away from from wheel rim.
Background technology
Generally, air-inflation tyre is by the weight of the air hydraulic support vehicle of inside tires.If do not exist air to press in the inside of tire, then travel under the tire state that face and wheel rim are close within it.
If force in this state to travel, then the sidewall portion of tire can damage, even to the tire place under repair of breakage, can not bring into play the tire function again.
In order to solve described problem, as shown in Figure 1, following proposal is arranged in the prior art, be provided with at the medial surface of sidewall portion 2 and strengthen rubber 5, when inside tires does not exist air to press, make the weight of the sidewall portion 2 supporting vehicles of tire thus.
But, there are the following problems for above-mentioned prior art, promptly, the rigidity of sidewall portion 2 exceeds standard, so the impact of transmitting by sidewall portion 2 from the road surface can't be cushioned in sidewall portion 2, thereby be delivered on the vehicle according to original size by tyre bead filler and bead core, therefore destroyed comfort and road-holding property by bus.
In addition, bead part 3 can not be adjacent to securely with wheel rim 6 because all loads concentrate on tyre bead bottom surface 32, so when sharply turning, bead part 3 can break away from from wheel rim 6, can cause large-scale accident.
Summary of the invention
In order to address the above problem, the object of the invention is to provide a kind of air-inflation tyre of anti-explosion, this tire improves the structure of tyre bead filler, can prevent the phenomenon that comfort by bus that the rigidity increase because of sidewall portion causes descends thus, and can prevent that tyre bead breaks away from from wheel rim when sharply turning.
To achieve these goals, the air-inflation tyre of anti-explosion of the present invention constitutes in the following manner.Promptly, comprise fetus face, sidewall portion and bead part, carcass is crossed in fetus face, sidewall portion and the bead part, be provided with reinforcement rubber in the inboard of sidewall portion, described bead part is made of bead core that twines many steel wires and the tyre bead filler that is arranged on bead core top, wherein, described tyre bead filler comprises the first tyre bead filler, the second tyre bead filler and the 3rd tyre bead filler, and the first tyre bead filler is arranged on the top of bead core; The second tyre bead filler is by carcass sealing and divide, and is arranged on the outside of the first tyre bead filler and is positioned at the top of rim flange; The 3rd tyre bead filler also is arranged on the outside of the first tyre bead filler and is positioned at the top of the second tyre bead filler, and adjoins the first tyre bead filler and arrive the middle part of carcass.
Description of drawings
Fig. 1 is the schematic sectional view of the anti-collapsed tire of prior art;
Fig. 2 is the schematic sectional view of anti-collapsed tire 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.
Fig. 2 is the airtyred schematic sectional view of anti-explosion of the present invention.
As shown in Figure 2, air-inflation tyre of the present invention comprises fetus face 1, sidewall portion 2 and bead part 3, and carcass 4 is crossed in fetus face 1, sidewall portion 2 and the bead part 3.Be provided with reinforcement rubber 5 in the inboard of sidewall portion 2.Bead part 3 is made of bead core 30 that twines many steel wires and the tyre bead filler 31 that is arranged on bead core 30 tops.Wherein, tyre bead filler 31 comprises: the first tyre bead filler 311 is arranged on the top of bead core 30; The second tyre bead filler 312 is arranged on the outside of the first tyre bead filler 311, and is positioned at the top of rim flange 61; The 3rd tyre bead filler 313 is arranged on the top of the second tyre bead filler 312.
In addition, 4 pairs first tyre bead fillers of carcass 311 carry out winding, and carry out winding from the lateral surface of the second tyre bead filler 312 to medial surface, winding the end of the carcass 4 behind the second tyre bead filler 312 be positioned at the inboard of the first tyre bead filler 311.
The tire of the present invention of Gou Chenging is formed with a plurality of tyre bead fillers 31 like this, particularly by making the second tyre bead filler 312 and the 3rd tyre bead filler 313 be positioned at the top of rim flange 61, to be delivered to the load of bead part 3 and impact by sidewall portion 2 thus and pass to rim flange 61 by the 3rd tyre bead filler 313 and the second tyre bead filler 312, can make load and impact dispersion, can improve comfort by bus, by the carcass tension force of carcass winding structure is regulated, increase at the bottom of the tyre bead 32 and the binding force of wheel rim 6, when sharply turning, can prevent that bead part 3 breaks away from from wheel rim 6.
The present invention is not limited to the foregoing description, can diversely be out of shape in the allowed band of technical conceive of the present invention and implements.
As mentioned above, the present invention has following effect.Promptly, the carcass tension force of the carcass winding structure by tire, when sharply turning, the large-scale accident that can prevent bead part to cause from the wheel rim disengaging, and, the load and the impact of transmitting by the strong sidewall portion of rigidity can be absorbed and cushion by being divided into each tyre bead filler a plurality of and that disperse to be provided with in wide region, thus, can prevent to reduce the phenomenon of comfort by bus because of the rigidity increase of sidewall portion.
