일반적으로 철도차량의 안전요소는 바퀴가 장착되는 대차프레임에 의해 크게 결정된다.In general, the safety factor of railway vehicles is largely determined by the bogie frame on which the wheels are mounted.

때문에 이러한 철도차량의 대차프레임의 안전시험은 항시적으로 하고 있는데, 이러한 안전시험은 크게 2가지 종류로 구분되는데, 이는 사람이 망치로 두들겨 나는 소리를 통해 대차프레임의 안전요소를 시험하는 간이 안전시험과, 별도의 시험장치에 설치하여 대차프레임의 하중을 시험하는 주 안전시험으로 구분된다.Therefore, the safety test of the bogie frame of such a railway vehicle is always performed, and these safety tests are largely divided into two types, which are simple safety tests in which the safety element of the bogie frame is tested through the sound of a hammer being hit by a human being. And, it is divided into the main safety test to test the load of the bogie frame by installing in a separate test device.

상기에서 후자인 주 안전시험은 객차에 대차프레임을 분리한 후 안전시험을 하게 되는데, 이때 상기 대차프레임은 바퀴와 현가장치 등 부가적인 장치를 분리한 후 대차프레임만을 시험장치에 올려놓고 하중 시험을 하게 된다.The latter main safety test is a safety test after separating the bogie frame to the passenger car, wherein the bogie frame is to separate the additional devices such as wheels and suspension, and then load the bogie frame only on the test device and load test Done.

이러한 대차프레임 시험장치는 본 출원인이 대한민국 특허출원 10-2007-85162호와, 대한민국 특허출원 10-2007-85174호 제시된 바 있다.Such a bogie frame testing apparatus has been proposed by the applicant of the Republic of Korea Patent Application No. 10-2007-85162, and the Republic of Korea Patent Application No. 10-2007-85174.

이하에서는 대한민국 특허출원 10-2007-85162호 및 대한민국 특허출원 10-2007-85174의 대차프레임 시험장치용 저널결합구조에 관하여 간단히 설명하기로 한다. Hereinafter, the journal combining structure for the bogie frame test apparatus of Korean Patent Application No. 10-2007-85162 and Korean Patent Application No. 10-2007-85174 will be briefly described.

도 1a는 종래의 제 1실시예에 따른 대차프레임 시험장치를 나타낸 사시도이고, 도 1b는 도 1a에서 발췌된 대차프레임의 시험상태를 나타낸 개념도이고, 도 2a는 종래의 제 2실시예에 따른 대차프레임 시험장치를 나타낸 사시도이고, 도 2b는 도 2a에서 발췌된 대차프레임의 시험상태를 나타낸 개념도이다.Figure 1a is a perspective view showing a bogie frame test apparatus according to a first embodiment of the prior art, Figure 1b is a conceptual diagram showing a test state of the bogie frame extracted in Figure 1a, Figure 2a is a bogie according to a second embodiment Figure 2 is a perspective view showing a frame testing apparatus, Figure 2b is a conceptual diagram showing a test state of the bogie frame extracted in Figure 2a.

도 1a 내지 도 2b에 도시된 바와 같이, 먼저 대차프레임 시험장치는 지지로드(50)를 통해 더미엑슬(20)을 지면에 이격시켜 지지시키고, 상기 더미엑슬(20)의 결합된 저널박스(30)의 상부에 대차프레임(10)을 안착시켜 유압가력기(P)를 통해 대차프레임(10)의 상부 및 측면에 힘을 가하여 대차프레임(10)에 각종 하중과 반력을 측정하는 장치이다.1A to 2B, the bogie frame test apparatus first supports the dummy axle 20 spaced apart from the ground through the support rod 50, and then combines the journal box 30 of the dummy axle 20. By mounting the balance frame 10 on the upper portion of the) is a device for measuring various loads and reaction forces on the balance frame 10 by applying a force to the upper and side surfaces of the balance frame 10 through the hydraulic press (P).

제 1실시예의 대차프레임 시험장치용 저널결합구조는 대차프레임(10)을 고정하기 위해 저널박스(30)에 결합봉(32)이 구비되어 있다.The journal coupling structure for the bogie frame test apparatus of the first embodiment is provided with a coupling rod 32 in the journal box 30 to fix the bogie frame 10.

따라서 도 1b와 같이 유압가력기(P)를 통해 대차프레임(10)에 수직하중을 가하면, 대차프레임(10)의 양측은 고정된 채 대차프레임(10)에 굴곡된 부분(A)에 응력이 과대하게 발생되어 실제 주행상태에 따른 대차프레임(10)의 요구조건을 발생시키기 어려웠다.Therefore, when a vertical load is applied to the bogie frame 10 through the hydraulic presser P as shown in FIG. 1B, stress is applied to the portion A that is bent in the bogie frame 10 while both sides of the bogie frame 10 are fixed. Excessively generated, it was difficult to generate the requirements of the bogie frame 10 according to the actual driving state.

이를 개선하고자 제 2실시예는 도 2a 및 도 2b와 같이, 저널박스(30)에 대차프레임(10)을 고정하기 위해 결합봉(32)을 대체하여 코일스프링(33)을 구비하였다.In order to improve this, the second embodiment is provided with a coil spring 33 to replace the coupling rod 32 to fix the bogie frame 10 to the journal box 30, as shown in Figure 2a and 2b.

하지만 상기 코일스프링(33) 역시 도 2b와 같이 유압가력기(P)를 통해 대차프레임(10)에 수직하중을 가하면 상기 대차프레임(10)은 코일스프링(33)의 과도한 수축으로 인해 대차프레임(10)의 양단부가 급격하게 바깥쪽으로 비틀림이 발생되어 이 역시 실제 주행상태에 따른 대차프레임(10)의 요구조건을 발생시키기 어려웠다.However, when the coil spring 33 also applies a vertical load to the bogie frame 10 through the hydraulic presser P as shown in FIG. 2B, the bogie frame 10 may be disposed of the bogie frame due to excessive contraction of the coil spring 33. Both ends of 10) are suddenly twisted outward, which is also difficult to generate the requirements of the bogie frame 10 according to the actual driving state.

즉, 실제 주행상태에서 대차프레임(10)에 가해지는 하중은 제 1실시예와 제 2실시예의 중간 상태가 가장 적절한데, 이를 위해 실제 주행상태에 따른 대차프레임(10)의 요구조건을 발생시킬 수 있는 구조의 장치가 요구되고 있는 실정이다.That is, the load applied to the bogie frame 10 in the actual driving state is most appropriate between the first embodiment and the second embodiment, and for this purpose, it is necessary to generate the requirements of the bogie frame 10 according to the actual driving state. There is a demand for a device having a structure that can be used.

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로, 본 발명의 목적은 주행중에 가해지는 대차프레임의 실제하중을 최대한 구현할 수 있도록 한 구조의 대차프레임 시험장치용 저널결합구조를 제공하는데 있다.The present invention has been made in view of the above problems, and an object of the present invention is to provide a journal coupling structure for a bogie frame test apparatus having a structure that can realize the maximum actual load of the bogie frame applied while driving.

더 나아가 본 발명의 목적은, 지지로드를 통해 더미엑슬을 지면에 이격시켜 지지시키고, 상기 더미엑슬의 상부에 대차프레임을 안착시켜 유압가력기를 통해 대차프레임의 상부 및 측면에 힘을 가하여 대차프레임에 각종 하중과 반력을 측정하기 위한 시험장치에 있어서, 상기 각 더미엑슬은 대차프레임을 안착시켜 지지하는 저널박스를 더 포함하여 이루어지되, 상기 대차프레임은 저널박스와 볼베어링 접촉되어 안착되는 것을 특징으로 하는 대차프레임 시험장치용 저널결합구조를 제공하는데 있다.Furthermore, an object of the present invention is to support the dummy axle on the ground through the support rod, seat the bogie frame on the top of the dummy axle, and apply a force to the bogie frame by applying a force to the top and the side of the bogie frame through the hydraulic press. In the test apparatus for measuring various loads and reaction forces, the dummy axle further comprises a journal box for supporting the bogie frame is seated, characterized in that the bogie frame is seated in contact with the ball bearing the journal box To provide a journal coupling structure for a bogie frame testing apparatus.

본 발명에 따른 대차프레임 시험장치용 저널결합구조에 따르면, 더미엑슬에 결합된 저널박스에 대차프레임을 볼베어링 접촉시켜 하중 시험시 대차프레임에 가해지는 집중 응력이나 과도한 휨 현상을 분산시킬 수 있어 주행중에 가해지는 대차프레임의 실제하중을 최대한 구현할 수 있는 특징이 있다.According to the journal coupling structure for the bogie frame testing apparatus according to the present invention, by contacting the bogie frame to the journal box coupled to the dummy axle, the concentrated stress or excessive bending phenomenon applied to the bogie frame during load testing can be dispersed. There is a characteristic that can realize the actual load of the applied bogie frame to the maximum.

이하에서는 본 발명에 따른 대차프레임 시험장치용 저널결합구조에 관하여 첨부되어진 도면과 함께 더불어 상세히 설명하기로 한다.Hereinafter will be described in detail with the accompanying drawings with respect to the journal coupling structure for a bogie frame test apparatus according to the present invention.

도 3a는 본 발명이 적용된 대차프레임 시험장치를 나타낸 구성도이고, 도 3b는 도 3a에서 발췌된 본 발명에 따른 대차프레임 시험장치용 저널결합구조를 나타낸 분해사시도이다.Figure 3a is a block diagram showing a bogie frame test apparatus applied to the present invention, Figure 3b is an exploded perspective view showing a journal coupling structure for the bogie frame test apparatus according to the present invention extracted from Figure 3a.

도 3a 및 도 3b에 도시된 바와 같이, 본 발명은 지지로드(50)를 통해 더미엑슬(20)을 지면에 이격시켜 지지시키고, 상기 더미엑슬(20)의 상부에 대차프레임(10)을 안착시켜 유압가력기(P)를 통해 대차프레임(10)의 상부 및 측면에 힘을 가하여 대차프레임(10)에 각종 하중과 반력을 측정하기 위한 시험장치에 있어서, 더미엑슬(20)에 결합된 저널박스(30)에 대차프레임(10)을 볼베어링(40)으로 접촉시켜 하중 시험시 대차프레임(10)에 가해지는 집중 응력이나 과도한 휨 현상을 분산시킬 수 있어 주행중에 가해지는 대차프레임(10)의 실제하중을 최대한 구현할 수 있도록 한 구조의 대차프레임 시험장치용 저널결합구조에 관한 것이다.As shown in FIGS. 3A and 3B, the present invention supports the dummy axle 20 spaced apart from the ground through the support rod 50, and mounts the bogie frame 10 on the dummy axle 20. In the test apparatus for measuring the various loads and reaction forces on the bogie frame 10 by applying a force to the upper and side surfaces of the bogie frame 10 through the hydraulic press (P), the journal coupled to the dummy axle 20 The bogie frame 10 is brought into contact with the box 30 with the ball bearing 40 to disperse concentrated stresses or excessive bending phenomena applied to the bogie frame 10 during the load test, and thus The present invention relates to a journal coupling structure for a bogie frame test apparatus having a structure to realize a maximum actual load.

여기서 더미엑슬(20)의 양측에는 각각 대차프레임(10)을 결합시키기 위한 저널박스(30)가 구비되어 있다.Here, both sides of the dummy axle 20 is provided with a journal box 30 for coupling the balance frame 10, respectively.

이러한 저널박스(30)는 볼베어링(40)을 통해 상기 대차프레임(10)을 구속하지 않고 지지하는 구조이다.The journal box 30 has a structure for supporting the bogie frame 10 without restraining it through the ball bearing 40.

때문에 대차프레임(10)은 저널박스(30)와 볼베어링(40)에 의해 접촉되어 안착되는 구조이다.Because of the bogie frame 10 is a structure that is contacted and seated by the journal box 30 and the ball bearing 40.

여기서 각 저널박스(30)는 볼베어링(40)이 부분 삽입되는 2개의 제 1컵(31)이 파여져 구성된다.Here, each journal box 30 is formed by digging two first cups 31 into which the ball bearing 40 is partially inserted.

그리고 대차프레임(10)은 하부에 볼베어링(40)이 부분 삽입되는 제 2컵(111)이 형성된 금속패드(11)가 부착되는 구조이다.In addition, the balance frame 10 has a structure in which a metal pad 11 having a second cup 111 into which the ball bearing 40 is partially inserted is attached.

따라서 제 1컵(31) 및 제 2컵(111)에 부분 삽입되는 볼베어링(40)은 이탈되지 않고, 안정적으로 대차프레임(10)을 지지할 수 있는 구조가 마련된다.Therefore, the ball bearing 40 partially inserted into the first cup 31 and the second cup 111 is not detached, and a structure capable of stably supporting the bogie frame 10 is provided.

여기서 상기 제 1컵(31) 및 제 2컵(111)은 볼베어링(40)의 크기에 의해 구속받지 않고 미세한 롤링이 이루어질 수 있도록 구면으로 이루지는 것이 아니하고, 타원 같은 비구면으로 형성하는 것이 바람직하다.In this case, the first cup 31 and the second cup 111 are not constrained by the size of the ball bearing 40 and are not formed in a spherical shape so that minute rolling can be made.

또한 상기 제 1컵(31) 및 제 2컵(111)의 깊이는 반분 된 볼베어링(40)을 기준으로 최소 1/2 이상 삽입되는 깊이로 형성하는 바람직하다.In addition, the depth of the first cup 31 and the second cup 111 is preferably formed to a depth that is inserted at least 1/2 or more based on the half-branched ball bearing 40.

이는 대차프레임(10)의 측면으로 힘을 가했을 때 볼베어링(40)의 이탈을 방지하기 위함이다.This is to prevent separation of the ball bearing 40 when a force is applied to the side of the bogie frame 10.

도 3c는 도 3a의 대차프레임 시험상태를 나타낸 개념도이다.3C is a conceptual diagram illustrating a bogie frame test state of FIG. 3A.

도 3b에 도시된 바와 같이, 저널박스(30)와 대차프레임(10)에 부착된 금속패드(11)의 사이에 볼베어링(40)을 개재하고, 유압가력기(P)를 통해 반복하중을 가한다.As shown in FIG. 3B, a ball bearing 40 is interposed between the journal box 30 and the metal pad 11 attached to the bogie frame 10, and a repeated load is applied through the hydraulic presser P. FIG. do.

그러면 대차프레임(10)은 최대 허용 변형량까지 볼베어링(40)에 의해 미끄러지듯이 지지되고, 볼베어링(40)은 대차프레임(10)에 수직 반력을 전달한다. Then, the bogie frame 10 is slidably supported by the ball bearing 40 to the maximum allowable deformation amount, and the ball bearing 40 transmits a vertical reaction force to the bogie frame 10.

그러면 대차프레임(10)은 전체적으로 하중과 반력이 고루 분포되어 집중 응력이나 과도한 휨 현상을 분산시킬 수 있어 주행중에 가해지는 대차프레임(10)의 실제하중을 최대한 구현할 수 있는 것이다.Then, the bogie frame 10 is to distribute the load and reaction force evenly as a whole to distribute the concentrated stress or excessive bending phenomena to realize the actual load of the bogie frame 10 applied during the driving to the maximum.

이상에서와 같이 본 발명에 따른 대차프레임 시험장치용 저널결합구조는 차량용 대차프레임, 중장비용 대차프레임의 하중시험장치에 다양하게 응용될 수 있음은 물론이다.As described above, the journal coupling structure for the bogie frame test apparatus according to the present invention can be variously applied to the load test apparatus for the bogie frame for a vehicle and the bogie frame for heavy equipment.
