Abstract

The utility model discloses a novel safety tire which comprises a tire tread, a sidewall, and a combined part of the tire and a rim; and the tire tread comprises tread patterns and a tire tread base with cord fabric layers, wherein the rigidity of the tire tread base and the combined part of the tire and the rim is more than 2 times of the rigidity of the sidewall of the tire. The cord fabric layers can be added to the tire tread base and the combined part of the tire and the rim. The rigidity of all parts of the tire is changed by changing the thickness of rubber or skeleton material, by changing the category of the rubber or the skeleton material or by changing both of them simultaneously. Without changing traditional tire production processes, the safety tire can not only prevent a motor vehicle from deflecting and losing control after flat tire but also can ensure the riding comfort.

Description

A kind of new type of safe tire

Technical field

The invention belongs to tire and make the field, relate in particular to the manufacturing of two-wheel car tires such as a kind of motor bike and battery-driven car.

Background technology

Two-wheel cars such as motor bike and battery-driven car are in use normal because various factors causes gas leakage at present, because gas leakage back air pressure lowers rapidly, vehicle body can produce the inclination beat, if the chaufeur reaction will cause car body out of control more slowly, falls car and hurts sb.'s feelings.The mentality of designing of safety tyre mainly contains two aspects both at home and abroad, and the one, the whole pressure release of tire when preventing to blow out mainly shows as change inner tube of a tyre structure, makes the single air chamber of the inner tube of a tyre become many air chambers; The 2nd, prevent to be pierced, between cover tire or the cover tire and the inner tube of a tyre, increase rigid material and increase tire intensity.These design most complex process, can not stop unexpected gas leak phenomenon fully, and have increased tire single-piece rigidity and reduced the traveling comfort of tire.

Summary of the invention

The purpose of the utility model technology is to overcome the shortcoming of existing safety tyre, by designing a kind of new tire section shape, by existing processes production, just can not only improve the safety when tire leaks gas suddenly in the motor-driven vehicle going process but also can guarantee traveling comfort.

Invention of the present utility model is achieved through the following technical solutions: increase crown position and tyre rim and the rigidity of closing the position, reduce the rigidity at position, sidewall, the change of rigidity can be by changing the thickness of rubber or framework material, also can be by changing the kind of rubber or framework material, also can the two change simultaneously and reach.Behind tire flat, air pressure reduces, but because that crown position and tyre rim the rigidity of closing the position is higher, not yielding, the distortion of tire can concentrate on the lower position, sidewall of rigidity always, and the distortion of tire both sides evenly, though therefore tire generation gas leakage can not produce serious inclination and beat, the driver has the enough time to make correct processing, thereby has guaranteed vehicle and rider's safety.And because position, the design sidewall rigidity is low, can play good buffer action when travelling, therefore can guarantee simultaneously the traveling comfort that drives.

Concrete scheme is: a kind of new type of safe tire, its structure comprise that the crown of tire, sidewall, tire and the wheel rim of tire the portion of closing; Crown comprises tread contour, the crown base portion of carcass plies is arranged, and wherein the rigidity of the portion of closing be that the rigidity on sidewall of tire is more than 2 times for crown base portion and tire and wheel rim.The best is that the rigidity of crown base portion is 2 to 5 times of the rigidity on the sidewall of tire; The rigidity that wheel rim the portion of closing is 2 to 5 times of the rigidity on the sidewall of tire.The rigidity of crown base portion is that 2 to 5 times of the rigidity on sidewall of tire and rigidity that rigidity that wheel rim the portion of closing is the sidewall of tire both overcame excessive reinforcement for 2 to 5 times and causes cost to increase, and realizes again not only improving the safety when tire leaks gas suddenly in the motor-driven vehicle going process but also guaranteeing traveling comfort.

Further the portion of closing and increase carcass plies at crown base portion and tire and wheel rim.Can also can be by changing the kind of rubber or framework material, also can the two changing the rigidity at each position of tire simultaneously by changing the thickness of rubber or framework material.

From top narration as can be seen: a kind of later-model safety tyre that the utility model is narrated, need not change existing tyre production technology, can prevent from behind the tire flat that the self-propelled vehicle beat is out of control can guarantee to drive traveling comfort again.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a conventional tyre cross-sectional structure scheme drawing;

Fig. 2 is a this patent tire cross-sectional structure scheme drawing;

Fig. 3 is the distortion situation of conventional tyre gas leakage rear tyre, easily produces beat;

Fig. 4 is the distortion situation of this patent tire flat rear tyre, is difficult for producing beat.

Among the figure, the tyre rim that a is the crown base portion of conventional tyre, sidewall that b is conventional tyre, c is conventional tyre close position, d be crown base portion, the e of this patent tire be sidewall, the f of this patent tire be the tyre rim of this patent tire close the position, g is that tread-rubber, h are that carcass plies, i are that the inner tube of a tyre, j are the carcass pliess that increases.

The specific embodiment

Realize the change of rigidity by changing material thickness in this example, crown base portion thickness a is about 1 to 1.5 times of sidewall thickness b among Fig. 1, and tyre rim and closed position thickness c and be about 1.5 to 2 times of sidewall thickness b.When tire leaks gas suddenly, cause tire not have pressing or during low pressure, because the sidewall rigidity is big, deformation place is not concentrated, tire can also can cause the continuous beat of vehicle toward right avertence toward left avertence, can't control.

Pass through among Fig. 2 to change rubber thickness and increase carcass plies j, the tire wheel rim of increase crown base portion thickness d and tire wheel and is closed position thickness, reduce the sidewall thickness e, make crown base portion thickness d be about 2 to 5 times of sidewall thickness e, tyre rim and is closed position thickness f and be about 2 to 5 times of sidewall thickness e.When tire leaks gas suddenly, cause tire not have pressing or during low pressure, because the sidewall is very thin, distortion concentrates on the sidewall, vehicle body only can be whole sink and can not deflect.

Increase the rigidity of tire, can also realize by using the rigidity better material by increasing rubber thickness and increasing carcass plies.

Claims

1. new type of safe tire, its structure comprise that the crown of tire, sidewall, tire and the wheel rim of tire the portion of closing; Wherein crown comprises tread contour, the crown base portion of carcass plies is arranged, and it is characterized in that: the thickness that crown base portion and tire and wheel rim the portion of closing is more than 2 times of sidewall thickness of tire.

2. new type of safe tire according to claim 1 is characterized in that: the thickness of crown base portion is 2 to 5 times of the thickness on the sidewall of tire.
