Description
본 고안은 공기입 타이어의 벨트 코드가 형상기억합금 재질로 이루어진 공기입 타이어에 관한 것이다.The present invention relates to a pneumatic tire in which the belt cord of the pneumatic tire is made of a shape memory alloy material.
일반적으로, 타이어가 고속주행으로 인하여 스탠딩 웨이브 포인트에 도달하면, 타이어의 트레드에 굴곡이 형성되어서 세퍼레이션(분리 : separation)이 발생하며, 한 번 완전히 스탠딩 웨이브 포인트를 지나게 된 타이어는 사용이 불가능하게 된다.In general, when a tire reaches a standing wave point due to high-speed driving, a bend is formed in the tread of the tire to cause separation, and a tire once completely past the standing wave point becomes unusable. do.
그래서 이와 같은 문제(즉, 속도내구력의 저하)를 해결하기 위한 방법중의 하나로서, 트레드 레디어스를 작게 만들어서 스탠딩 웨이브 발생시간을 지연시켜 속도내구력을 향상시키는 방법이 있다.Therefore, one of the methods for solving such a problem (that is, lowering the speed durability) is to improve the speed durability by making the tread radiance small and delaying the standing wave generation time.
그러나, 종래의 공기입 타이어에서는 트레드의 이상 마모등과 같은 현상 때문에, 속도내구력을 향상시키기 위한 트레드 레디어스의 변경이 용이하지 않았다. 즉, 속도내구력이 저하되었을 때, 속도내구력의 향상을 위하여 트레드 레디어스 조정을 행하면 타이어의 다른 성능에 영향을 주기 때문에 트레드 레디어스의 조절이 용이하지 않다.However, in the conventional pneumatic tire, due to a phenomenon such as abnormal wear of the tread, it is not easy to change the tread radials for improving the speed durability. That is, when the speed endurance is lowered, adjusting the tread radials for the improvement of the speed endurance is not easy to adjust the tread radials because it affects other performance of the tire.
따라서, 본 고안은, 상기와 같은 종래기술에서 문제가 되는 것들을 해결하기 위하여, 벨트 코드를 형상기억합금 토드로 함으로써, 평상시에는 종래 타이어의 벨트코드와 동일한 효과를 내다가, 고속주행시에는 타이어의 트레드 레디어스를 줄어들게 하여 스탠딩 웨이브 발생포인트를 지연시켜, 공기입 타이어의 속도내구력을 향상함이 본 고안의 과제이다.Therefore, the present invention, in order to solve the problems in the prior art as described above, by using the belt cord as a shape memory alloy tod, it usually produces the same effect as the belt cord of conventional tires, the tire tread during high-speed driving It is a task of the present invention to reduce the radiance and delay the standing wave generation point, thereby improving the speed and durability of the pneumatic tire.

3 : 트레드3: tread
본 고안은 제1도와 같은 구조로서, 1은 형상기억합금 코드(2)로 이루어진 벨트부이고, 제2도에서 나타내는 종래 타이어의 일반 스틸 코드(5)로 이루어진 벨트부(4)와 동일한 형상을 이루고 있다.The present invention has a structure as shown in FIG. 1, wherein 1 is a belt part made of the shape memory alloy cord 2, and has the same shape as the belt part 4 made of the general steel cord 5 of the conventional tire shown in FIG. It is coming true.
제3도는 본 고안의 자동차가 일반주행할 때의 타이어의 상태를 나타내는 도면으로서, 본 고안의 벨트부(1)가 종래의 벨트부(4)아 동일한 트레드 레디어스를 이루다가, 자동차의 속도가 일정속도 이상으로 되면(타이어에서 임계속도 이상이 되면 타이어 내부에는 고온의 열이 발생한다) 형상기억합금(2)가 이미 기억된 기억형상(즉, 트레드 레디어스가 일반 상태보다 작은 모양)으로 회귀하여, 제4도에서 나타내는 바와 같이 트레드 레디어스가 줄어든 타이어로 변형된다.3 is a view showing the state of the tire when the vehicle of the present invention when driving in general, the belt portion 1 of the present invention achieves the same tread radials as the conventional belt portion 4, the speed of the vehicle If the speed is higher than a certain speed (when the tire exceeds the critical speed, high temperature heat is generated inside the tire), the shape memory alloy 2 returns to the memory shape that is already stored (that is, the tread radiance is smaller than the normal state). Thus, as shown in FIG. 4, the tread radiance is deformed to reduce the tire.
본 고안에서 사용한 형상기억합금 코드(2)는, 상온에서는 일반적 금속과 동일한 운동을 하다가 고온에 도달하며는 형상기억합금 코드(2)에 기억되어져 있는 기억형상(즉, 본 고안에서 사용한 방법은 종래의 트레드 레디어스보다 더 작게 함)으로 되돌아 가려는 회귀력이 발생하여 기억된 형상으로 되돌아가므로 연하여, 스탠딩 웨이브 발생시간을 지연시키는 작용을 한다.The shape memory alloy cord (2) used in the present invention is a memory shape stored in the shape memory alloy cord (2) after reaching the high temperature while performing the same motion as a general metal at room temperature (that is, the method used in the present invention Regression force is generated to return to the memorized shape, which is softer, thus delaying the standing wave generation time.
형상기억합금 코드(2)를 사용함으로써, 고속주행시 타이어에 발생하는 스탠딩 웨이브 발생시간을 지연시켜 타이어의 속도내구력을 향상시키는 효과가 있다.By using the shape memory alloy cord 2, there is an effect of delaying the standing wave generation time generated in the tire during high-speed driving to improve the speed durability of the tire.
본 고안은 스탠딩 웨이브(Standing wave : 공기압이 불충분한 상태에서 고속으로 주행할 때 타이어의 접지부 하중개방측에 생기는 파상 현상) 발생에 의한 타이어의 속도내구력의 저하를 방지하기 위하여, 종래의 단순 스틸 코드로 이루어진 벨트코드를 형상기억합금 코드로 대체함으로써, 스탠딩 웨이브 발생시간을 지연시켜 타이어의 속도내구력을 향상시키는데 그 목적이 있다.The present invention is a conventional simple steel in order to prevent a reduction in the tire's speed and durability due to the generation of a standing wave (waveform phenomenon occurring on the load-opening side of the tire when running at high speeds under insufficient air pressure). By replacing the belt cord made of cord with the shape memory alloy cord, the purpose is to improve the speed durability of the tire by delaying the standing wave generation time.
