Description

철도차량용 제동실린더 유니트{Brake Cylinder Unit For Railway-vehicle}Brake Cylinder Unit For Railway-vehicle}

본 발명은 철도차량용 제동실린더 유니트에 관한 것으로서, 보다 상세하게는 상용제동과 주차제동을 겸하면서 수동으로 주차제동을 완해할 수 있도록 된 철도차량용 제동실린더 유니트에 관한 것이다.The present invention relates to a braking cylinder unit for a railroad vehicle, and more particularly, to a braking cylinder unit for a railroad car, which can perform parking braking manually as well as commercial braking and parking braking.

일반적으로 철도차량의 제동장치는 휠 디스크 제동 타입과 답면 제동 타입의 시스템이 이용되고 있으며, 차량의 특성에 따라 그 제동 시스템이 선택되어 사용되고 있다.In general, a brake system of a railroad vehicle uses a wheel disc braking type and a turning surface braking type system, and the braking system is selected and used according to the characteristics of the vehicle.

이 중 휠 디스크 구조로 이루어진 브레이크시스템은 운행중인 차량에 제동이 가해지게 되면 캘리퍼스가 작동되면서 차축의 소정 위치에 설치된 휠 디스크를 가압하여 작동력이 발생되는 것이며, 또한 차량의 전 후방에 위치한 차륜과 근접된위치에 별도의 실린더 유니트가 각각 대각선 방향으로 설치되어 있어 사용제동과 주차제동이 각기 따로 이루어지게 되었다.Among these, the brake system composed of the wheel disk structure generates the operating force by pressing the wheel disk installed at the predetermined position of the axle while the caliper is operated when braking is applied to the driving vehicle. Separate cylinder units are installed diagonally in the same position, so braking and parking braking are performed separately.

그러나, 차량의 지속적인 운행 및 제동에 따라 휠 디스크와 수시로 접촉되는 라이닝의 마모로 셋팅된 초기 간격의 변화로 제동성능이 저하되고,정기 및 수시점검을 통해 이를 일일이 점검하면서 간격을 조정해야만 했으며, 제동력의 저하는 곧바로 차량 안전사고의 발생률을 증가시켜 승객의 안전을 해하게 될 뿐만 아니라 수시로 행하게 되는 정비로 차량 운행에 막대한 지장을 주는 문제점이 있었다.However, due to the constant running and braking of the vehicle, the braking performance is reduced due to the change in the initial interval set by the wear of the lining that is in frequent contact with the wheel disk. Deterioration of the vehicle immediately increases the incidence of car accidents, which not only impairs the safety of the passengers, but also has a problem that greatly affects the operation of the vehicle.

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로, 제동실린더 자체에서 초기 간격의 변화를 자동으로 조정하도록 하여 정비에 소요되는 시간이 저감됨으로써 차량의 원활한 운행이 보장되고, 하나의 실린더에 상용제동 및 주차제동을 겸하도록 하여 각각의 차륜에서 제동이 행할 수 있도록 하여 제동에 따른 신뢰도를 향상시킴과 동시에 차량 사고를 극감시킴으로써 승객의 안전이 최대한 보장되는데 그 목적이 있다.The present invention has been made in view of the above problems, by reducing the time required for maintenance by automatically adjusting the change of the initial interval in the braking cylinder itself ensures smooth running of the vehicle, commercial braking on one cylinder And parking braking to perform braking at each wheel, thereby improving reliability according to braking and reducing vehicle accidents, thereby ensuring maximum passenger safety.

먼저 도 3을 참조하면, 제동실린더 유니트(10)가 차량에 장착되면, 주차제동실린더(70)에 압축공기가 유입되고, 이로 인해 주차피스톤(74)이 상향 이동되면서 가이드슬리브(78) 역시 베어링스프링(82)의 팽창력에 의해 상향 이동된 상태를 유지하게 된다.First, referring to FIG. 3, when the braking cylinder unit 10 is mounted on a vehicle, compressed air flows into the parking braking cylinder 70, and as a result, the parking piston 74 moves upward, thereby bearing the guide sleeve 78 as well. The state in which the spring 82 is moved upward by the expansion force is maintained.

도 4 내지 도 5에 도시된 바와 같이, 주차제동이 완해된 상태에서 주브레이크를 조작하게 되면 압축공기가 실린더부(40) 내부로 유입되면 주피스톤(44)은 이동하게 되고, 이로 인해 자동간격조절장치(50)와 제동헤드(62)가 작업자에 의해 미리 설정된 적용스트로크 "A(Application stroke)"만큼 이동하게 된다.As shown in Figures 4 to 5, when the main brake is operated in a state in which parking braking is relaxed, when the compressed air flows into the cylinder portion 40, the main piston 44 moves, and thus the automatic interval The adjusting device 50 and the braking head 62 are moved by an application stroke "A (Application stroke)" preset by the operator.

계속해서 압축공기가 실린더부(40)로 공급됨으로써 트러스트너트(55) 외주연에 끼움 설치된 조절스프링(53)의 반력이 탄성스프링(49) 반력보다 커지고피스톤(44)의 이동되는 힘이 증가되어 커플링 스트로크 "C(Coupling stroke)"만큼 이동된다.Then, the compressed air is supplied to the cylinder portion 40, so that the reaction force of the control spring 53 installed on the outer circumference of the thrust nut 55 is larger than the reaction force of the elastic spring 49, and the force of the piston 44 is increased. Coupling stroke "C (Coupling stroke)" is moved.

이때까지 주피스톤(44)의 총 스트로크는 "A+C"가 된다.At this point, the total stroke of the main piston 44 becomes "A + C".

또한, 공기압이 계속 증가하면 제동력은 증가하게 되고, 실린더 내부 및 캘리퍼에서 발생되는 탄성변형만큼의 스트로크 즉, "E(Elastic deformation stroke)"만큼 주피스톤(44)과 제동헤드(62)가 이동하게 된다. 여기서, 피스톤(44)의 스트로크는 "A+C+E"가 되고, 제동헤드(62)의 스트로크는 "A+E"가 된다.In addition, if the air pressure continues to increase, the braking force is increased, and the main piston 44 and the braking head 62 move by the stroke equal to the elastic deformation generated in the cylinder and the caliper, that is, "E (Elastic deformation stroke)". do. Here, the stroke of the piston 44 becomes "A + C + E", and the stroke of the braking head 62 becomes "A + E".

브레이크의 작동에 의한 마모나 과대 간격 "V"가 발생되면, "A"스트로크가 행하여진 다음, 상기 조절스핀들(52)이 조절스프링(53)의 반력에 의해 회전되어지면 트러스트너트(55)와의 결합면이 제동헤드(62)측으로 이동되어 간격 "V"가 보상된 후 커플링 스트로크 "C"와 탄성변형 스트로크 "E"가 행하여 최종적인 제동이 이루어진다.When wear or excessive distance "V" is generated by the operation of the brake, "A" stroke is performed, and then when the adjusting spindle 52 is rotated by the reaction force of the adjusting spring 53, the thrust nut 55 After the engagement surface is moved to the braking head 62 to compensate for the gap "V", the coupling stroke "C" and the elastic deformation stroke "E" are performed to achieve final braking.

이 때의 피스톤(44)의 스트로크는 "A+C+E"이고, 제동헤드(62)의 스트로크는 "A+E+V"가 된다.The stroke of the piston 44 at this time is "A + C + E", and the stroke of the braking head 62 is "A + E + V".

상기 제동실린더 유니트(10)의 제동패드 교환시 행하여지는 리셋팅은 리셋너트(66)가 시계방향으로 회전되면 셋스크류(54)가 회전되어 제동헤드(72)가 하향 이동되면서 이루어진다.The reset performed when the brake pad of the brake cylinder unit 10 is replaced is performed when the reset nut 66 is rotated in the clockwise direction, and the set screw 54 is rotated to move the brake head 72 downward.

또한, 상기 적용스트로크 "A"가 필요에 의해 조절될 경우, 실린더몸체(12)와 제동헤드(62) 사이에 체결되어 있는 벨로우즈(67)을 분해하고, 상기 실린더몸체(12)와 조절튜브(57)를 체결하고 있는 셋스크류(54)를 해제시킨 후에 조절튜브(57)를 반시계방향으로 회전시키게 되면 상기 적용스트로크 "A"는 길어지게 되고 시계방향으로 회전하게 되면 짧아짐으로써 그 길이를 조절할 수 있다.In addition, when the application stroke "A" is adjusted as necessary, the bellows 67 is fastened between the cylinder body 12 and the braking head 62, and the cylinder body 12 and the control tube ( 57) When the adjusting tube 57 is rotated counterclockwise after the set screw 54 is released, the application stroke "A" becomes long, and when it is rotated clockwise, the length is adjusted. Can be.

By moving downward), the commercial braking cylinder 40 is operated so that parking braking is performed on the vehicle. When compressed air flows back into the parking braking cylinder 70, the parking braking of the vehicle is released.

만약, 차량이 주차제동된 상태 즉, 도 6에 도시된 상태에서 공기압을 이용하여 완해시킬 수 없는 상태에 놓이게 되면, 도 7에 도시된 바와 같이, 작동부재(26)를 실린더 몸체(12)의 외측으로 당김으로써 래칫돌기(75)의 결합이 해제되고, 래칫휠(76)과 가이드슬리브(78)가 회전가능하게 되면 트러스트샤프트(77)는 주피스톤(47)에 밀려 상승하게 되면서 피스톤(44, 74)은 각각 격벽(70)의 일측면에 맞닿게 됨으로써 도 2의 상태로 복귀하게 된다.If the vehicle is placed in a state in which the vehicle is parked and braked, that is, in a state in which it cannot be relaxed using air pressure in the state shown in FIG. 6, as shown in FIG. 7, the operating member 26 of the cylinder body 12 is removed. When the ratchet protrusion 75 is released by pulling outward and the ratchet wheel 76 and the guide sleeve 78 are rotatable, the thrust shaft 77 is pushed up by the main piston 47 and the piston 44 is raised. , 74 are in contact with one side of the partition wall 70 to return to the state of FIG.

이로써, 차량의 주차제동은 수동으로 완해되고, 차량은 이동이 가능하게 되며, 주차제동실린더(70)에 압축공기가 다시 유입되면 주차제동은 자동으로 작동하게 된다.Thus, the parking braking of the vehicle is manually released, the vehicle can be moved, and when the compressed air flows back into the parking braking cylinder 70, the parking braking is automatically activated.
