Description

철도 차량용 고무완충기{Rubber-Shock absorber component for railway car truck}Rubber shock absorbers for railway vehicles {Rubber-Shock absorber component for railway car truck}

본 발명은 철도 차량용 고무완충기에 관한 것으로써, 보다 상세하게는 철도차량의 운행에 있어서 출발과 정지시 객차와 객차를 연결한 요크에 발생하는 큰 충격과 함께 소음 및 진동을 효과적으로 흡수할 수 있는 철도 차량용 고무완충기에 관한 것이다.The present invention relates to a rubber shock absorber for a railway vehicle, and more particularly, a railway capable of effectively absorbing noise and vibration together with a large shock generated in a yoke connecting a carriage and a carriage at the start and stop of a railway vehicle. A rubber shock absorber for a vehicle.

일반적으로 철도차량용 고무완충기는 철도차량의 차량과 차량을 연결하는 연결기 장치중 충격을 완화하기 위해서 설치되는 종래의 장비로는 도 7 (a)(b)와 같이 구성되어 있다.In general, a rubber shock absorber for a railway vehicle is a conventional equipment installed to mitigate the impact of the connector device for connecting the vehicle and the vehicle of the railway vehicle is configured as shown in Figure 7 (a) (b).

그리고 상기와 같이 형성된 고무 완충기는 도 7의 (a)와 같이 일반적인 철판의 양면에 고무 쿠션패드를 접착시킨 상태에서 다시 철판과 고무의 외주연을 별도의 고무부재로 연장시켜 접착시키는 방법이 있다.In addition, the rubber buffer formed as described above has a method of extending the outer periphery of the iron plate and the rubber to a separate rubber member in a state in which the rubber cushion pad is bonded to both sides of the general iron plate as shown in FIG.

그러나 이와 같은 방법은 상기 고무 큐션패드와 연결된 고무부재의 외주연이그대로 외부로 노출되어 있으므로 인하여 열차의 주행이나 정지 이외에 차량의 순간 가속으로 차량끼리 연결시키는 상황에서 충격완하용 고무부재는 반복되는 충격에 의해 접착면이 떨어지거나 파손되는 문제점으로 인하여 수시로 고무부재를 교체하거나 아니면 매번 수리해야 하는 번거러움이 발생한다.However, in such a method, since the outer circumference of the rubber member connected to the rubber cushion pad is exposed to the outside, the shock-absorbing rubber member is subjected to repeated shocks in a situation in which the vehicles are connected to each other by the momentary acceleration of the vehicle in addition to the driving or stopping of the train. Due to the problem that the adhesive surface is dropped or broken by the problem often occurs the need to replace the rubber member or repair every time.

또한, 상기와 같은 문제점을 일부 해결한 수단으로는 도 7의 (b)와 같이 다수개의 중간삽입철판의 전체면에 쿠션고무를 몰딩성형하여 양측 외측철판과 중간삽입철판들 사이의 상하부에는 간격유지 및 충격을 흡수할 수 있도록 구성된 방법이 있다.In addition, as a means for solving some of the above problems, as shown in Figure 7 (b) by molding the cushion rubber on the entire surface of the plurality of intermediate inserting iron plate to maintain the gap between the upper and lower sides between the two outer side iron plate and the intermediate insertion iron plate And a method configured to absorb shocks.

그러나 이와 같은 방법은 차량의 충격이 쿠션고무에 직접전달 되도록 구성되어 있으나, 이는 차량의 충격이 단계적으로 전달되지 않고 그 파장이 몰딩된 선두의 삽입철판의 접촉면에 집중적으로 반복되므로 인하여 상기 접촉면은 약화되면서 감싸여져 있는 고무몰딩이 쉽게 떨어져 나가는 단점과 함께 쿠션부재 전체를 교환시켜야 하는 문제점을 지니고 있다.However, this method is configured to directly transmit the impact of the vehicle to the cushion rubber, but the contact surface is weakened because the impact of the vehicle is not transmitted step by step and the wavelength is repeated intensively on the contact surface of the inserted insert plate. While having a disadvantage that the wrapped rubber molding easily falls off, it has a problem of replacing the entire cushion member.

한편, 이와 같은 문제를 일부 해결한 선행기술로는 실용신안등록출원제2000-003825호의 "기차, 지하철용 완충기"가 있다.On the other hand, the prior art that solves some of these problems is the "train, subway shock absorber" of the Utility Model Registration Application No. 2000-003825.

이는 몸체에 다수의 요홈이 형성되어 자바라 형태를 갖는 고무제의 탄성부재와 상기 탄성부재 상하단부에 플랜지를 갖는 인서트를 삽착시켜 접착제로 고정하여서 된 완충기와 상기 완충기와 완충기를 연결시켜 차량과 차량 사이의 양측에 설치하여 충격을 흡수할 수 있도록 되어 있다.A plurality of grooves are formed in the body to insert a rubber elastic member having a bellows shape and an insert having a flange at the upper and lower ends of the elastic member to connect the shock absorber and the shock absorber secured by adhesive to connect the shock absorber with the vehicle. It is installed on both sides of the to absorb shocks.

그러나 상기와 같이 형성된 자바라식 완충기로는 고속으로 운행하는 차량에 적용하기에는 부적합하며, 또한 수시로 객차와 객차를 연결시킬 때 발생하는 충격과 소음을 효과적으로 방지할 수 없는 구조라 고속기차용으로 사용하기에는 적합하지 못한 문제점이 있다.However, the bellows type shock absorber formed as described above is not suitable to be applied to a vehicle traveling at high speed, and is not suitable to be used for a high-speed train because it cannot effectively prevent the shock and noise generated when the passenger car is frequently connected to the passenger car. There is a problem.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한것으로서, 보다 간단하면서 안전하게 철도 차량용 고무완충기를 형성시킬 수 있도록 철판 플레이트전체를 완충부재로 덮은 상태에서 압축 성형시켜 고정각부와 다수의 에어 배출부를 갖는 철도 차량용 고무완충기를 제공하는데 그 목적이 있다.The present invention has been made in order to solve the above problems, and has a fixed angle portion and a plurality of air discharge portion by compression molding in the state covered with the entire sheet plate with a cushioning member to more easily and safely form a rubber shock absorber for railway vehicles The object is to provide a rubber shock absorber for railway vehicles.

상기의 목적을 달성하기 위하여 철판 플레이트의 표면에 다수의 요부홈을 형성시킨 상태에서 완충부재를 상기 철판 플레이트 상부와 하부에 밀착시킨 상태로 코팅시키면 상기 철판 플레이트 표면에 형성된 다수의 요부홈에 상기 완충부재가 동시에 충전되면서 하나의 고무완충기가 형성됨과 함께 상기 고무완충기의 표면과 저면에는 고정각부가 돌출될 수 있는 철도 차량용 고무완충기를 제공하고자 하는 것이다.In order to achieve the above object, the buffer member is formed in a state in which a plurality of recess grooves are formed on the surface of the iron plate plate, and the cushioning member is coated in a state of being in close contact with the upper and lower portions of the iron plate plate. It is to provide a rubber shock absorber for railroad cars that can be fixed at the surface and the bottom surface of the rubber shock absorber and the rubber buffer is formed at the same time as the member is filled at the same time.

이하, 첨부된 도면에 관련하여 본 발명의 실시예에 의해서 이루어진 그 구성을 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings will be described in detail the configuration made by the embodiment of the present invention.

도 1은 본 발병의 실시예에 의해 완성된 고무완충기의 제조방법을 나타낸 공정도이며, 도 2의 (a)(b)는 본 발명의 실시례에 의해 완성된 고무완충기의 단면도이고, 도 3은 본 발명에 의해 완성된 고무완충기의 사시도이고, 도 4는 본 발명에 의해 완성된 고무완충기의 측면도이고, 도 5은 본 발명의 요부를 발췌하여 확대한 상태의 측면도이고, 도 6는 본 발명의 요부가 조립된 사용 상태의 단면도이고, 도 7의 (a)(b)은 종래의 일반적인 고무완충기의 측면도이다.1 is a process chart showing a method of manufacturing a rubber shock absorber completed by the embodiment of the present invention, Figure 2 (a) (b) is a cross-sectional view of the rubber shock absorber completed by an embodiment of the present invention, Figure 3 4 is a perspective view of a rubber shock absorber completed by the present invention, Figure 4 is a side view of the rubber shock absorber completed by the present invention, Figure 5 is a side view of an enlarged state by extracting the main portion of the present invention, Figure 6 is Fig. 7 (a) and (b) are side views of a conventional general rubber shock absorber.

먼저 도 1과 같이 하부 금형틀(16)과 상부 금형틀(16)을 준비한 상태에서 상기 하부 금형틀(16) 표면에 소정의 두께를 갖는 완충부재(21)를 올려놓게 된다.First, as shown in FIG. 1, a buffer member 21 having a predetermined thickness is placed on a surface of the lower mold 16 in a state in which the lower mold 16 and the upper mold 16 are prepared.

이때, 상기의 완충부재(21)는 고무재질로 형성시키는 것이 바람직하나, 탄력성이 우수한 합성수지로도 상기의 완충부재(21)를 구성시켜도 무방하다.At this time, the buffer member 21 is preferably formed of a rubber material, but may be configured of the buffer member 21 also made of synthetic resin having excellent elasticity.

그리고 완충부재(21)의 조성물인 고무의 물리적인 성질을 개선시킬 수 있도록 촉진제 외에 카본을 첨가하는데 이는 단순히 보강체의 역할뿐만 아니라 고무의 물성을 향상시켜 내구성을 높이기 위해 사용된다.In addition to the accelerator to add the carbon to improve the physical properties of the rubber composition of the shock absorbing member 21, it is used not only to enhance the durability of the rubber but also to improve the physical properties of the rubber.

이와 같이 형성된 완충부재(21)의 고무조성물들은 고온의 온도인 160℃∼ 150℃ 온도에서 적당량의 시간동안 가열시키게 된다.The rubber compositions of the buffer member 21 thus formed are heated at an appropriate temperature of 160 ° C. to 150 ° C. for an appropriate amount of time.

그리고 상기의 성질을 가진 하부 완충부재(21)의 상측에 고무와 플레이트를 접착시키는데 필요한 고무 접착제를 도포한 요부홈(11)이 다수형성된 철판 플레이트(10)를 올려놓게 된다.And the upper plate of the lower plate member 10 having the above properties to the plate plate 10 is formed a number of recessed grooves (11) coated with a rubber adhesive necessary for adhering the rubber and the plate.

다음 상기 철판 플레이트(10) 표면에 소정의 두께로 형성된 완충부재(21)를 덮은 상태에서 대기한다.Next, the steel plate 10 is waited while covering the buffer member 21 formed to a predetermined thickness on the surface of the iron plate 10.

이때, 철판 플레이트(10)에 형성된 상부 고무층(12)과 하부 고무층(13)의 완충부재(21)는 동일한 소재를 사용하는 것이 바람직하며, 탄성을 보강하기 위하여 유황이 참가되는 것은 일반적인 방법과 동일하다.At this time, the upper rubber layer 12 formed on the iron plate plate 10 and the buffer member 21 of the lower rubber layer 13 is preferably made of the same material, sulfur is added to reinforce elasticity is the same as the general method. Do.

상기와 같이 철판 플레이트(10)의 표면과 하면에 완충부재(21)로 형성된 상부 고무층(12)과 하부 고무층(13)을 하나로 형성시키기 위해서는 금형틀(16)에 의해 사출성형이나, 프레스를 이용한 압착방법을 사용한다.As described above, in order to form the upper rubber layer 12 and the lower rubber layer 13 formed of the buffer member 21 on the surface and the lower surface of the iron plate plate 10 as one, injection molding or press using the mold 16 is used. Use the crimp method.

이와 같은 방법에 의해 완성된 고무완충기(17)의 상하측에는 상하부 고무층(12)(13)이 형성되는 것이다.Upper and lower rubber layers 12 and 13 are formed on the upper and lower sides of the rubber shock absorber 17 completed by such a method.

그리고 상기 상하부 고무층(12)(13)이 돌출되면서 다수의 고정각부(19)가 형성되며, 이때 상기의 고정각부(19)에는 도 3과 같이 고정구(20)가 각각 구성된다.As the upper and lower rubber layers 12 and 13 protrude, a plurality of fixing angles 19 are formed, and the fixing angles 19 are formed in the fixing angles 19 as shown in FIG. 3.

한편, 상기 고정각부(19)에 형성된 고정구(20)에는 도 6과 같이 타측의 고정각부(19)가 수용되는 방식으로 수 개의 고무완충기(17)를 연속적으로 조립되게 형성하였다.On the other hand, the fastener 20 formed in the fixed angle portion 19 was formed to be assembled several rubber buffers 17 in a manner that the other fixed angle portion 19 is accommodated as shown in FIG.

이때, 고정각부(19)에 형성된 경사각은 고정구(20)에 형성된 경사와 일체가되는 구조이므로 보다 조립이 용이할 뿐만 아니라, 외부의 충격에서도 힘의 분산을 효율적으로 할 수 있는 구조이다.At this time, the inclination angle formed on the fixing angle portion 19 is a structure that is integral with the inclination formed on the fixture 20, and is easy to assemble, and also has a structure that can effectively distribute the force in the external impact.

이는 사다리꼴로 형성된 고정각부(19)와 고정구(20)가 도 6과 같이 조립되어 고무완충기(17)에 발생되는 충격을 단계적으로 흡수할 수 있는 것이다.This is because the fixed angle portion 19 and the fastener 20 formed in a trapezoidal shape as shown in Figure 6 can absorb the shock generated in the rubber shock absorber 17 step by step.

상기와 같은 구성으로 이루어진 본 발명의 작용과 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of the above configuration in detail as follows.

먼저 사출성형이나 프레스의 압착에 의해 형성된 고무완충기(17)의 상하측에는 복수의 고정각부(19)와 동일한 갯수의 고정구(20)가 각각 구성된다.First, upper and lower sides of the rubber shock absorber 17 formed by injection molding or pressing of the press are configured with the same number of fasteners 20 as the plurality of fixing angles 19.

또한, 고무완충기(17)를 이루는 상부 고무층(12)과 하부 고무층(13)은 철판 플레이트(10)에 형성된 요부홈(11)을 관통하여 일체로 연결되게 하였다.In addition, the upper rubber layer 12 and the lower rubber layer 13 constituting the rubber shock absorber 17 is to be integrally connected through the recessed grooves 11 formed in the iron plate plate (10).

한편, 상기 고정구(20)와 고정각부(19)를 철판 플레이트(10) 표면에 형성시킬 때에는 소량의 에어와 가스가 철판 플레이트(10)와 완충부재(21)사이에 발생하지만 이는 완충부재(21) 외주연에 형성된 수개의 연결구(14)에 의해 제거될 수 있도록 하였다.On the other hand, when the fastener 20 and the fixed angle portion 19 is formed on the surface of the iron plate plate 10, a small amount of air and gas is generated between the iron plate plate 10 and the buffer member 21, but this is the buffer member 21 ) Can be removed by several connectors 14 formed on the outer periphery.

따라서 에어와 가스를 배출시키기 위한 연결구(14)는 철판 플레이트(10) 외부에 수 개 돌출되게 형성된다.Therefore, the connector 14 for discharging air and gas is formed to protrude several outside the iron plate plate (10).

이와 같이 구성된 고무완충기(17)는 도 6과 같이 다수개를 포개어 이를 조립시킨 다음 고정 브래킷(22)에 다시 조립시킨 후, 철도 차량의 요크(미도시됨)에 고정시키게 되는 것이다.The rubber shock absorber 17 configured as described above is stacked and assembled as shown in FIG. 6, and then assembled to the fixing bracket 22, and then fixed to the yoke (not shown) of the railway vehicle.

따라서, 열차 차랑과 차량 사이의 요크에 고정된 고무완충기(17)에 의해서 운행중 제동을 걸더라도 고무완충기(17)에 형성된 고정각부(19)와 조립된 고정구(20)가 수축되면서 충격과 압력을 흡수하게 되므로 승객이 승차한 차량의 객실에는 그 충격이 덜해지는 것이다.Therefore, even when braking is carried out by the rubber shock absorber 17 fixed to the yoke between the train lane and the vehicle, the fastener 20 assembled with the fixed angle portion 19 formed on the rubber shock absorber 17 contracts, thereby reducing shock and pressure. As it is absorbed, the shock is lessened in the passenger cabin of the vehicle.

그리고 본 발명에서 이용되는 탄성부재인 고무재는 경도 80±5, 인장강도 200kg/㎠ 이상, 신장률 200%, 내노화성: 노화후의 인장신장 변화률 ±25% 이내,압축영구줄음률 25%이하의 규격을 갖는 고무제를 사용하였다.And the rubber material of the elastic member used in the present invention has a hardness of 80 ± 5, tensile strength of 200kg / ㎠ or more, elongation rate 200%, aging resistance: within the tensile elongation change rate of ± 25% after aging, compressive permanent shrinkage 25% or less A rubber having was used.

따라서 본 발명은 직선 주행에서의 충격과 커브 주행 및 차량과 차량의 연결시 발생되는 충격의 힘을 과학적으로 흡수하여 분산시키게 된다.Therefore, the present invention scientifically absorbs and disperses the force of the impact generated in the straight line driving and the curve driving and the impact generated when the vehicle is connected to the vehicle.

또한, 철판 플레이트(10) 상측에 형성된 상부 고무층(12)과 하부 고무층(13)을 일체로 형성시킴으로 인하여 제작이 보다 용이하면서 완충력을 몇 배로 향상시킬 수 있는 것이다.In addition, since the upper rubber layer 12 and the lower rubber layer 13 formed on the upper side of the iron plate plate 10 are integrally formed, the buffering force can be improved by several times while being easier to manufacture.

이상에서 설명한 본 발명은, 본 발명이 속하는 기술분야에서 통상의 지식을가진자에 있어 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러가지 치환, 변형 및 변경이 가능하므로 전술한 실시례 및 첨부된 도면에 한정되는 것은 아니다.The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains.

이상과 같이 본 발명에 의하면 철판 플레이트와 일체로 형성된 상하측의 고무층에 의해 차량에 가해지는 충격을 최소화시킴은 물론 승객이 탑승한 객차까지 충격을 전달하지 않게 되므로 승차감을 향상시키는 동시에 고무완충기의 형상을 간단하게 만들 수 있으므로 인하여 작업의 능률을 높일 수 있는 특징이 있다.As described above, according to the present invention, the upper and lower rubber layers formed integrally with the iron plate plate minimize the impact applied to the vehicle, and do not transmit the impact to the passenger car. Because it can be made simple, there is a characteristic that can increase the work efficiency.

그리고 차량 주행과 제동시 수축 작용이 발생하더라도 다수의 고정구에 조립된 고정각부가 수축되었다 다시 탄발하게 되므로 극히 적은 충격과 그 충격을 자연스럽게 흡수하여 분산시킬 수 있는 효과가 있다.In addition, even if the contraction action occurs during vehicle driving and braking, the fixed angle parts assembled in the plurality of fasteners are contracted and rebounded, so that there is an extremely small shock and the effect can be naturally absorbed and dispersed.
