Description

기차, 지하철용 완충기{a buffer used in subway and train}A buffer used in subway and train}

본 고안은 기차, 지하철의 차량과 차량 사이에 설치되는 완충기(BUFFER)에 관한 것으로서, 특수 고무제질로 된 자바라 형태의 탄성부재를 구비시켜 상하단에 인서트(insert)를 삽입 고정한 다음 기차 또는 지하철의 차량과 차량이 연결되는 사이에 설치하여 완충 장치로 사용함으로써 충격 완화와 소음을 방지할 수 있도록 고안 된 열차 및 지하철용 완충기에 관한 것이다.The present invention relates to a shock absorber (BUFFER) installed between a vehicle and a train of a train, subway, and equipped with a bellows-shaped elastic member made of a special rubber material, and inserting and inserting the inserts at the upper and lower ends of the train or subway. The present invention relates to a shock absorber for trains and subways, which is designed to prevent shocks and prevent noise by being installed between a vehicle and a vehicle, and used as a shock absorber.

종래에도 기차 또는 지하철의 차량과 차량 사이의 연결부에 완충 장치를 설치하여 충격을 흡수하고 소음을 감소시키도록 하고 있으나. 기존의 이러한 완충 장치는 코일 형태의 금속 스프링 또는 스프링쇼버, 유압쇼버 등을 사용함으로써, 어느 정도의 충격은 흡수할 수 있으나, 금속 스프링의 탄성 한도에 미치지 못하거나, 이를 넘을 경우 충격이 차량 객실에 전달되므로 승차감이 떨어져 승객이 불편함을 느끼게 되며, 소음이 발생되는 불편이 있었다. 또한 기차, 지하철 주행시 커브된 레일을 지나갈 경우에는 차량과 차량의 연결부가 내측은 좁은 각도를 이루고 외측은 각도가 넓게 형성되므로 금속재질의 완충 장치는 수축 및 인장될 때 서로 마찰이 생겨 마모가 쉽게 되므로 부품 소모가 빨리 이루어져 차량 점검 및 보수비가 상승되는 문제점이 있었다.Conventionally, a shock absorber is installed at a connection portion between a vehicle or a train in a train or subway to absorb shocks and reduce noise. Existing shock absorbers use a coil-shaped metal spring, spring shock absorber, hydraulic shock absorber, etc., but can absorb some shock, but if the shock does not reach or exceed the elastic limit of the metal spring, The passengers feel uncomfortable because they are delivered, and there is a inconvenience that noise is generated. In addition, when passing a curved rail when driving a train or subway, the connection between the vehicle and the vehicle forms a narrow angle on the inside and a wide angle on the outside, so that the metal shock absorbers are easily rubbed with each other when contracted and tensioned. There was a problem that the parts consumption is fast, the vehicle inspection and maintenance costs increase.

본 고안은 이와 같은 문제점을 해결하기 위해 고안한 것으로서, 몸체에 다수의 요홈이 형성되어 자바라 형태를 갖는 고무제의 탄성부재와;The present invention has been devised to solve such a problem, and a plurality of grooves are formed in the body to form a rubber elastic member having a bellows shape;

상기 탄성부재 상하단부에 플랜지를 갖는 인서트(insert)를 삽착시켜 접착제로 고정하여서 된 완충기(buffer)의 구성이다. 이와 같이 구성된 본 고안은 기차 또는 지하철의 차량과 차량 사이에 설치하여 미세한 충격에서부터 큰 충격까지 자연스럽게 흡수하여 차량의 객실 승객에게 향상된 승차감을 제공할 수 있도록 하고, 탄성부재가 특수 고무로 이루어져 마찰시 소음이 없으며, 커브 지점에서 완충기에 불균형 수축이 일어나더라도 마모와 소음이 발생되지 않도록 고안된 것이다.It is a configuration of a buffer in which an insert having a flange is inserted into upper and lower ends of the elastic member and fixed with an adhesive. The present invention configured as described above is installed between a vehicle or a vehicle of a train or subway, so as to naturally absorb from a small shock to a large shock to provide an improved ride comfort for passengers in the cabin of the vehicle, and the elastic member is made of special rubber to make noise during friction It is designed to prevent abrasion and noise even if unbalanced shrinkage occurs in the shock absorber at the curve point.

이하 첨부 도면에 의거하여 본 고안을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

기차 또는 지하철의 차량(10)과 차량(10) 사이에 설치되는 완충 장치에 있어서,In the shock absorber provided between the vehicle 10 and the vehicle 10 of the train or subway,

몸체에 다수의 요홈(3)이 형성되어 자바라 형태를 갖는 고무제의 탄성부재(2)와;A plurality of grooves 3 formed in the body to form a rubber elastic member 2 having a bellows shape;

상기 탄성부재(2) 상하단부에 플랜지(4')(5')를 갖는 인서트(insert)(4)(5)를 삽착시켜 접착제로 고정하여서 된 완충기(buffer)(1)와 완충기(1)를 연결시켜 충격 흡수와 소음을 방지할 수 있도록 구성된 것이다. 미설명 부호 6은 완충기와 완충기 사이에 개재되어 충격 흡수와 유격방지를 위한 패킹이다.Buffer (1) and Buffer (1) formed by inserting inserts (4) (5) having flanges (4 ', 5') at upper and lower ends of the elastic member (2) and fixed with an adhesive. By connecting the shock absorber and noise is configured. Reference numeral 6 is a packing between the shock absorber and the shock absorber for shock absorption and play prevention.

이와 같이 구성된 본 고안은 몸체에 자바라 형태로 다수의 요홈(3)이 형성된 탄성부재(2)의 상하단에 인서트(4)(5)를 삽입시켜 접착제로 고정된 완충기(buffer ASS′Y)(1)를 구성한 다음 기차 또는 지하철의 차량(10)과 차량(10) 사이에 차량의 길이 방향으로 설치하되 완충기(1)의 일측 인서트(4) 플랜지(4')와 다른 완충기(1)의 일측 인서트(5) 플랜지(5') 사이에 패킹(6)을 개재시켜 볼트로 결합하여 도3 및 도4와 같이 완충기를 설치하게 된다.The present invention configured as described above is inserted into the upper and lower ends of the elastic member (2) formed with a plurality of grooves (3) in the form of bellows on the body (buffer ASS'Y) (1) ) And then installed in the longitudinal direction of the vehicle between the vehicle 10 and the vehicle 10 of the train or subway, but one insert (4) of the shock absorber 1 flange (4 ') and one insert of the other shock absorber (1) (5) The packing 6 is interposed between the flanges 5 'by bolts to install the shock absorbers as shown in FIGS.

상기와 같이 차량(10)과 차량(10) 사이의 양측에 완충기(1)와 완충기(1)를 직렬 상태로 연결시켜 설치함으로써 기차 또는 지하철 운행 중 제동을 걸더라도 후부에 연결되어 주행되던 각 차량(10)의 압력이 완충기(1)에 가해지면 다수의 요홈(3)을 갖는 자바라 형태의 고무제 탄성부재(2)가 수축되면서 충격과 압력을 흡수하게 되므로 승객이 승차한 차양의 객실에는 충격이 전달되지 않게 된다.As described above, by connecting the shock absorber 1 and the shock absorber 1 in series between the vehicle 10 and the vehicle 10 in a state of being installed in series, each vehicle that is connected to the rear of the vehicle even when braking while operating a train or subway When the pressure of (10) is applied to the shock absorber (1), the bellows-type rubber elastic member (2) having a plurality of grooves (3) is contracted to absorb shock and pressure, so that the passenger's cabin of the passenger cabin Will not be delivered.

본 고안에서 이용되는 고무제의 탄성부재(2)는 경도 50∼60°, 인장강도 250kgf/㎠ 이상, 신장률 700%, 내노화성:노화후의 인장신장 변화율 ±20% 이내, 압축영구줄음률 20% 이하, 반발탄성 65∼70의 규격을 갖도록 탄성부재(2)를 형성하였다.Rubber elastic member 2 used in the present invention has a hardness of 50 ~ 60 °, tensile strength of 250kgf / ㎠ or more, elongation rate 700%, aging resistance: less than ± 20% of tensile elongation change after aging, 20% compression set Hereinafter, the elastic member 2 was formed so as to have a specification of resilience 65 to 70.

이렇게 된 본 고안은 직선 주행에서의 충격 흡수 뿐만 아니라 기차 또는 지하철 커브 주행시 차량(10)과 차량(10) 사이의 양측에 설치된 완충기(1)가 내측으로는 약 149㎜ 수축되고, 외측으로는 약 301.3㎜까지 신장되도록 한 것이다.In this way, the present invention not only absorbs shock in a straight line, but also cushions 1 installed on both sides between the vehicle 10 and the vehicle 10 when traveling in a train or subway curve. It is to be extended to 301.3㎜.

상기 본 고안의 완충기(1)는 기존의 스프링 쇼버가 설치된 중심선에 일치하도록 연장 설치되므로 제동시 또는 충격시 스프링 쇼버와 함께 충격 완화 및 주행속도에 대한 압력을 분산하게 된다.The shock absorber 1 of the present invention is installed to extend to match the centerline of the existing spring absorber, so that the pressure of the shock absorber and the traveling speed are distributed together with the spring shocker during braking or shock.

또한 본 고안은 완충기(1)의 몸체인 탄성부재(2)가 자바라 형태를 이루고 있어 커브길이나, 주행시 제동시 수축 작용이 일어나더라도 다수의 요홈(3)이 수축되었다 다시 탄발하게 되므로 극히 적은 충격과 큰 충격을 모두 다 자연스럽게 흡수 분산하게 되며, 마찰이 발생하지 않고 마모가 생기지 않아 소음이 없도록 한 것이다.In addition, the present invention is the elastic member (2), the body of the shock absorber (1) forms a bellows shape, even if the curbway, even when the contraction action during braking during the driving, a number of grooves (3) is contracted again and elasticity is extremely small impact Both natural and big shocks are absorbed and dispersed naturally, and there is no noise because no friction occurs and no wear occurs.

이와 같이 된 본 고안은 완충기를 자바라 형태의 고무제 탄성부재를 사용함으로써 가해지는 충격을 최소화시킴은 물론 승객이 탑승한 객차까지 충격을 전달하지 않게 되므로 승차감을 향상시키는 동시에 기존의 금속제 완충기와는 달리 수축, 탄발시 마찰이 발생하더라도 소음이 전혀 발생하지 않아 소음 공해를 방지하도록 된 것이다. 또한 본 고안은 제동시 속도의 가압이나, 커브 주행시 완충기가 수축되더라도 극히 미세한 마모가 이루어지므로 부품 수명이 오래 지속되어 완충기의 수리 교체비를 절감할 수 있게 된 효과를 갖게 되었다.Thus, the present invention minimizes the shock applied by using the bellows-type rubber elastic member, and does not transmit the shock to the passenger car, thereby improving ride comfort and unlike the conventional metal shock absorbers. When friction occurs during shrinkage or explosion, noise is not generated at all, preventing noise pollution. In addition, the present invention has the effect of reducing the cost of repair and replacement of the shock absorber due to the long life of the parts, even if the pressure is applied during braking or the shock absorber shrinks during curve driving.
