Description

철도차량 대차용 볼스터의 사이드 베어링{Side bearing of bolster for railroad car trucks}Side bearing of bolster for railroad car trucks}

본 고안은 철도차량 대차용 볼스터의 사이드 베어링에 관한 것으로서, 보다 상세하게는 마찰캡과 탄성체의 탄성체 블록이 분리되어 있으며, 탄성체 블록 내에 중공부가 형성된 철도차량 대차용 볼스터의 사이드 베어링에 관한 것이다.The present invention relates to a side bearing of a bolster for a railway vehicle bogie, and more particularly, to a side bearing of a bolster for a railway vehicle bogie, in which a friction cap and an elastic block of an elastic body are separated and a hollow part is formed in the elastic block.

일반적으로 철도화물 차량은 차량몸체의 세로 중심선에 직각으로 대차가 놓이고 레일을 따라 이동하는 바퀴가 대차에 구비된다. 그리고 상기 대차는 차량 몸체를 회전 가능하게 지지하는 볼스터를 갖는다. 차량 몸체는 주행 중에 대차 상에서 진동하게 되는데, 이것을 감쇠시키기 위해 볼스터에 사이드 베어링이 장착된다.In general, a rail freight car is placed at right angles to the longitudinal center line of the vehicle body, the wheel is provided with a wheel that moves along the rail. The trolley has a bolster rotatably supporting the vehicle body. The vehicle body vibrates on the bogie while driving, and side bearings are mounted on the bolster to dampen it.

그러나, 상기와 같은 종래의 철도차량 대차용 볼스터의 사이드 베어링은 상하 진동의 감쇠 효과가 적고 요잉(yawing)을 감쇠시키지 못하는 문제점이 있었다.However, the side bearings of the conventional bolster for railroad car trolleys have a problem that the damping effect of the vertical vibration is small and the yawing is not damped.

따라서, 본 고안의 목적은 차량 몸체의 상하 진동을 감쇠시키는 효과를 개선할 뿐만 아니라 요잉을 감쇠시킬 수 있는 철도차량 대차용 볼스터의 사이드 베어링을 제공하는 것이다.Accordingly, an object of the present invention is to provide a side bearing of a bolster for a railroad car bogie that can attenuate yawing as well as improve the effect of damping up and down vibration of the vehicle body.

이와 같은 목적을 달성하기 위한 본 고안에 따른 철도차량 대차용 볼스터의 사이드 베어링은, 하우징이 볼트에 의해 볼스터에 체결된 철도차량 대차용 볼스터의 사이드 베어링에 있어서, 상기 하우징은 일체형으로 중간벽을 경계로 하여 제1 요홈 및 제2요홈이 형성되고, 상기 제1요홈에 롤러가 안착되며, 제2요홈에 2개의 탄성체 블록이 마주보게 배치되고, 상기 탄성체 블록의 상부면에 마모캡이 놓이게 되고, 제1요홈의 하부에 빈 공간이 형성되고, 제2요홈의 바닥면은 중심부분이 주위보다 낮고, 'へ'형상이 중심을 경계로 하여 서로 대칭되는 것을 그 특징으로 한다.In the side bearing of the railroad vehicle bogie bolster according to the present invention for achieving the above object, in the side bearing of the railroad vehicle bogie bolster, the housing is fastened to the bolster by a bolt, the housing integrally bounds the intermediate wall By the first A groove and a second groove are formed, a roller is seated in the first groove, two elastic blocks are disposed to face the second groove, a wear cap is placed on an upper surface of the elastic block, The empty space is formed in the lower portion, the bottom surface of the second groove is characterized in that the central portion is lower than the surroundings, 'へ' shape is symmetrical with each other on the basis of the center.

이하, 본 고안의 바람직한 실시예를 첨부된 도면에 의하여 더욱 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

도 1 및 도 2 는 본 고안에 의한 사이드 베어링(20)이 볼스터(10) 상에서 중심볼(12)의 외측에 장착된 상태를 도시한 것이다. 도 3 및 도 4 는 본 고안에 따른 사이드 베어링(20)을 도시한 것으로서, 본 고안에 따른 사이드 베어링(20)은 하우징(22)이 볼트(15)에 의해 볼스터(10)에 체결된다.1 and 2 illustrate a state in which the side bearing 20 according to the present invention is mounted on the outside of the center ball 12 on the bolster 10. 3 and 4 show the side bearing 20 according to the present invention, the side bearing 20 according to the present invention is the housing 22 is fastened to the bolster 10 by the bolt (15).

상기 하우징(22)은 일체형으로 중간벽(26)을 경계로 하여 제1요홈(24) 및 제2요홈(25)이 형성되고, 상기 제1요홈(24)에 롤러(30)가 안착되며, 상기 제2요홈(25)에 2개의 탄성체 블록(34)(36)이 마주보게 배치되고, 상기 탄성체 블록(34)(36)의 상부면에 마모캡(50)이 놓이게 된다.The housing 22 is integrally formed with a boundary between the intermediate wall 26 and the first groove 24 and the second groove 25 are formed, the roller 30 is seated in the first groove 24, Two elastic blocks 34 and 36 are disposed to face each other in the second recess 25, and a wear cap 50 is placed on an upper surface of the elastic blocks 34 and 36.

또한, 상기 하우징(22)은 제1요홈(24)의 하부에 빈 공간(27)이 형성된다.In addition, the housing 22 has an empty space 27 formed in the lower portion of the first recess 24.

제2요홈(25)의 바닥면(28)은 중심부분이 주위보다 낮고, 'へ'형상이 중심을 경계로 하여 서로 대칭된다.The bottom surface 28 of the second groove 25 has a central portion lower than the surroundings, and the 'へ' shape is symmetric with each other with the center as the boundary.

상기 롤러(30)는 하우징(22)의 중간벽(26)과 측벽(23)에 의해 좌우 이동이 제한된다.The roller 30 is limited to the left and right movement by the intermediate wall 26 and the side wall 23 of the housing 22.

상기 제1탄성체 블록(34)은 경사진 상부면(38)과, 상기 상부면(38)에서 수직 하게 연장되는 수직부(40)(41)와, 상기 수직부(40)(41) 사이에 형성된 중공부(42)로 구성된다. 그리고, 상기 제1수직부(40)는 상부가 하부보다 두꺼우며, 하단부가 제2수직부(41)의 하단부보다 짧다.The first elastomer block 34 is perpendicular to the inclined top surface 38 and the top surface 38. It consists of a hollow portion 42 formed between the vertical portion 40, 41 and the vertical portion 40, 41 that extends. The upper portion of the first vertical portion 40 is thicker than the lower portion, and the lower portion thereof is shorter than the lower portion of the second vertical portion 41.

상기 제2탄성체 블록(36)은 제1탄성체 블록(34)보다 그 형상이 같으며, 제1탄성체 블록(34)에 대해 대칭적으로 배치되므로써, 마모캡(50)이 안착되는 상부면의 단면이 'V' 형상을 이룬다.The second elastomer block 36 has the same shape as the first elastomer block 34, and is symmetrically disposed with respect to the first elastomer block 34, so that the cross section of the upper surface on which the wear cap 50 is seated. This forms a 'V' shape.

상기 상부면(38)은 구멍(43)이 형성되며, 상기 구멍(43) 둘레에 환형상의 제2탄성체(44)가 형성되고, 제2탄성체(44)의 중공에 마모캡(50)의 돌부(51)(52)가 각각 끼워진다.The upper surface 38 has a hole 43 is formed, the annular second elastic body 44 is formed around the hole 43, the protrusion of the wear cap 50 in the hollow of the second elastic body 44 51 and 52 are respectively fitted.

상기와 같이 구성된 본 고안에 의한 철도차량 대차용 볼스터의 사이드 베어링은 탄성체 블록(34)(36) 및 마모캡(50)이 차량 몸체(미도시)의 진동을 감쇠시키고, 상기 차량 몸체가 요잉할 때 롤러(30)가 제1요홈(24)의 범위에서 좌우로 이동하므로서 차량 몸체가 좌우로 진동하는 것을 감쇠 시킨다. 특히 제2요홈(25)의 바닥면(28)의 중심부분이 주위보다 낮고, 'へ'형상이 중심을 경계로 하여 서로 대칭되고, 상기 탄성체 블록(34)(36)의 상부면의 단면이 'V' 형상을 이루어 마모캡(50)이 힘을 받았을 때 어느 쪽으로 영구 변형되지 않으며, 중공부(42)를 포함하기 때문에 진동 흡수가 상당히 증가된다.The side bearings of the bolster for railroad vehicle trolleys according to the present invention configured as described above are the elastic blocks 34 and 36 and the wear cap 50 to damp the vibration of the vehicle body (not shown), the vehicle body yawing When the roller 30 moves to the left and right in the range of the first groove 24 to damp the vibration of the vehicle body from side to side. In particular, the center portion of the bottom surface 28 of the second groove 25 is lower than the surroundings, the 'へ' shape is symmetrical with each other around the center, and the cross-sections of the upper surfaces of the elastic blocks 34 and 36 are The 'V' shape does not permanently deform when the wear cap 50 is subjected to force, and includes a hollow portion 42, so vibration absorption is considerably increased.

또한, 마모캡(50)만을 교체할 수 있어 경제적이다.In addition, it is economical because only the wear cap 50 can be replaced.

상술한 바와 같이 본 고안에 의한 철도차량 대차용 볼스터의 사이드 베어링은 차량 몸체의 상하 진동을 상당히 개선할 뿐만 아니라 요잉을 감쇠시킬 수 있는 효과가 있다.As described above, the side bearings of the bolster for railroad vehicle trolleys according to the present invention not only significantly improve the up and down vibration of the vehicle body but also have the effect of damping yawing.
