Description

듀얼 메스 플라이휠Dual scalpel flywheel

본 발명은 동력 전달을 행하는 플라이휠에 관한 것으로서, 특히, 구동 중에 발생되는 부재들 사이의 충돌을 효과적으로 완충할 수 있도록 하는 듀얼 메스 플라이휠에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flywheel for power transmission, and more particularly to a dual scalpel flywheel that can effectively dampen collisions between members generated during driving.

자동차 엔진에는 구동계의 비틀림으로 인한 진동을 저감하기 위하여 듀얼 메스 플라이휠(Dual Mass Flywheel, DMF)이 적용되고 있다.Dual mass flywheel (DMF) is applied to automobile engines to reduce vibrations caused by torsion of the drive system.

이러한 듀얼 메스 플라이휠은 프라이머리 메스(Primary mass)와 세컨더리 메스(Secondary mass)를 연결해 주는 구동플레이트가 프라이머리 메스에 장착된 아크 스프링과 연동하여 움직이면서, 아크 스프링의 댐핑 작용에 의해서 엔진과 변속기 사이의 충격을 완화하여 기어 노이즈, 바디 부밍 등 차량의 급가속에 의한 진동과 소음을 저감하는 역할을 행한다.This dual scalpel flywheel moves the drive plate connecting the primary mass and the secondary mass in conjunction with the arc spring mounted on the primary scalpel, and the damping action of the arc spring between the engine and the transmission. It mitigates shock and reduces vibration and noise caused by rapid acceleration of vehicles such as gear noise and body booming.

상기한 바와 같은 기술구성에 의해 엔진의 구동력이 프라이머리 메스에 전달되면 프라이머리 메스가 회전되면서 구동플레이트를 회전시키게 되므로 변속기와 연결된 세컨더리 메스를 회전시키게 된다.When the driving force of the engine is transmitted to the primary scalpel by the technical configuration as described above, the primary scalpel is rotated to rotate the driving plate, thereby rotating the secondary scalpel connected to the transmission.

이때, 프라이머리 메스의 회전력은 아크 스프링의 일측 단부를 가압하게 되고, 구동플레이트는 아크 스프링의 타측 단부에 의해 가압되어 회전된다.At this time, the rotational force of the primary scalpel is to press one end of the arc spring, the drive plate is pressed by the other end of the arc spring is rotated.

따라서 엔진의 구동력에 의해 프라이머리 메스가 급격히 회전되거나 세컨더리 메스의 회전 속도가 급격히 감소될 때에 발생되는 프라이머리 메스와 구동플레이트 사이의 충돌을 아크 스프링에 의해 방지할 수 있게 된다.Therefore, it is possible to prevent the collision between the primary scalpel and the driving plate generated when the primary scalpel is rapidly rotated by the driving force of the engine or the rotational speed of the secondary scalpel is sharply reduced by the arc spring.

상기한 기술구성은 본 발명의 이해를 돕기 위한 배경기술로서, 본 발명이 속하는 기술분야에서 널리 알려진 종래기술을 의미하는 것은 아니다.The above technical configuration is a background art for helping understanding of the present invention, and does not mean a conventional technology well known in the art.

일반적인 듀얼 메스 플라이휠은 아크 스프링으로 이루어지는 완충부재에 의해서만 완충작동이 이루어지기 때문에 프라이머리 메스가 급격히 회전되거나 세컨더리 메스의 회전 속도가 급격히 감소될 때에 발생되는 충격이 아크 스프링의 완충 성능 이상으로 발생되면 진동, 소음 및 파손이 발생될 수 있는 문제점이 있다. 따라서 이를 개선할 필요성이 요청된다.In general, the dual scalpel flywheel is cushioned only by a shock absorbing member made of an arc spring. Therefore, when the primary scalpel rotates rapidly or the rotational speed of the secondary scalpel decreases sharply, the shock generated when the secondary scalpel exceeds the arc spring damping performance is vibrated. There is a problem that noise and breakage may occur. Therefore, there is a need for improvement.

본 발명은 상기와 같은 문제점들을 개선하기 위해 안출된 것으로서, 구동 중에 발생되는 충격을 다수 차례에 걸려 완충할 수 있도록 하는 듀얼 메스 플라이휠을 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object thereof is to provide a dual scalpel flywheel capable of buffering a shock generated during driving a plurality of times.

또한, 상기 커버 플레이트에는 상기 제1완충부재를 가압하는 제1가압부와, 상기 구동 플레이트에 연결되는 지지부재가 관통되는 홀부가 형성되고, 상기 홀부에는 상기 제2완충부재를 가압하는 제2가압부가 형성되는 것을 특징으로 한다.In addition, the cover plate is formed with a first pressing portion for pressing the first buffer member, a hole portion through which the support member connected to the drive plate is formed, the second portion for pressing the second buffer member in the hole portion It is characterized in that the addition is formed.

도 1 내지 도 8을 참조하면, 본 발명의 일 실시예에 따른 듀얼 메스 플라이휠은 구동부로부터 구동력이 전달되는 프라이머리 메스(10)와, 프라이머리 메스(10)에 결합되는 커버 플레이트(20)와, 커버 플레이트(20)에 의해 회전되는 구동 플레이트(30)와, 구동 플레이트(30)에 결합되어 종동부에 회전력을 전달하는 세컨더리 메스(40)와, 커버 플레이트(20)와 구동 플레이트(30) 사이에 개재되는 완충부재(50)와, 완충부재(50)의 유동을 억제하는 고정부(70)와, 완충부재(50)가 커버 플레이트(20)와 구동 플레이트(30)에 접촉되지 않게 하는 마감부(90)를 포함한다.1 to 8, a dual scalpel flywheel according to an embodiment of the present invention includes a primary scalpel 10 to which driving force is transmitted from a driving unit, and a cover plate 20 coupled to the primary scalpel 10. , The drive plate 30 rotated by the cover plate 20, the secondary scalpel 40 coupled to the drive plate 30 to transmit rotational force to the follower, the cover plate 20, and the drive plate 30. The buffer member 50 interposed therebetween, the fixing part 70 which suppresses the flow of the buffer member 50, and the buffer member 50 do not come into contact with the cover plate 20 and the drive plate 30. Finish 90.

여기서, 구동부는 차량의 경우 엔진을 의미하며 엔진의 구동축과 프라이머리 메스(10)가 연결되고, 프라이머리 메스(10)의 테두리에 커버 플레이트(20)의 테두리가 용접되어 엔진이 구동되면 프라이머리 메스(10)와 커버 플레이트(20)가 동일한 속도로 회전된다.Here, the driving unit means an engine in the case of a vehicle, and the drive shaft of the engine and the primary scalpel 10 are connected, and the edge of the cover plate 20 is welded to the edge of the primary scalpel 10 to drive the engine. The scalpel 10 and the cover plate 20 are rotated at the same speed.

구동 플레이트(30)는 프라이머리 메스(10)와 커버 플레이트(20) 사이에 회전 가능하게 설치되고, 커버 플레이트(20)의 외측에 회전 가능하게 배치되는 세컨더리 메스(40)와 연결부재(86)에 의해 결합된다.The driving plate 30 is rotatably installed between the primary scalpel 10 and the cover plate 20, and the secondary scalpel 40 and the connection member 86 which are rotatably disposed outside the cover plate 20. Are combined by.

커버 플레이트(20)는 중앙에 소정치 이상의 홀부(22)가 형성되는 환형으로 이루어지기 때문에 이 홀부(22)를 통해 구동 플레이트(30)와 세컨더리 메스(40)가 연결될 수 있게 된다.Since the cover plate 20 is formed in an annular shape in which a hole portion 22 having a predetermined value or more is formed in the center, the driving plate 30 and the secondary scalpel 40 can be connected through the hole portion 22.

세컨더리 메스(40)와 구동 플레이트(30)에는 다수 개의 체결홀부(36, 42)가 구비되어 리벳과 같은 연결부재(86)에 의해 결합이 이루어지고, 프라이머리 메스(10)에 지지부재(82) 및 베어링(84)이 설치되어 구동 플레이트(30) 및 세컨더리 메스(40)가 회전 가능하게 지지된다.The secondary scalpel 40 and the driving plate 30 are provided with a plurality of fastening holes 36 and 42 to be coupled by a connecting member 86 such as a rivet, and the supporting member 82 to the primary scalpel 10. ) And a bearing 84 are rotatably supported by the drive plate 30 and the secondary scalpel 40.

완충부재(50)는 커버 플레이트(20)와 구동 플레이트(30) 사이에 개재되어 구동력 전달을 행함과 동시에 커버 플레이트(20)와 구동 플레이트(30) 사이에 발생되는 충격을 완충하는 제1완충부재(52)와, 커버 플레이트(20)와 구동 플레이트(30) 사이에 개재되어 2차 완충작동을 행하는 제2완충부재(54)를 포함한다.The shock absorbing member 50 is interposed between the cover plate 20 and the drive plate 30 to transmit the driving force and at the same time to cushion the shock generated between the cover plate 20 and the drive plate 30. 52 and a second buffer member 54 interposed between the cover plate 20 and the drive plate 30 to perform the secondary shock absorbing operation.

여기서, 제1완충부재(52)는 다수 개가 소정 간격을 유지토록 배치되고 제1완충부재(52) 사이에는 고정부(70)가 설치되어 프라이머리 메스(10)의 테두리 측에 환형을 이루도록 배치된다.Here, a plurality of first buffer members 52 are arranged to maintain a predetermined interval and the fixing portion 70 is installed between the first buffer members 52 to form an annular shape on the edge side of the primary scalpel 10. do.

고정부(70)는 제1완충부재(52)의 단부에 설치되어 제1완충부재(52)가 원주 방향으로 유동 가능하고 반경 방향으로 유동되는 것을 억제하는 캡(72)과, 캡(72) 사이에 개재되어 캡(72)이 반경 방향으로 유동되는 것을 억제하는 스토퍼(74)를 포함한다.Fixing portion 70 is provided at the end of the first buffer member 52, the cap 72 and the cap 72 for preventing the first buffer member 52 can flow in the circumferential direction and flow in the radial direction, The stopper 74 is interposed between the cap 72 to prevent the cap 72 from flowing in the radial direction.

따라서 프라이머리 메스(10)가 회전되어 원심력이 발생될 때에 캡(72)이 제1완충부재(52)의 양단부를 고정하고, 스토퍼(74)에 의해 캡(72)이 프라이머리 메스(10)의 반경 방향으로 유동되는 것이 억제되므로 제1완충부재(52)가 프라이머리 메스(10)와 접촉되는 것을 억제하게 된다.Therefore, when the primary scalpel 10 is rotated to generate the centrifugal force, the cap 72 fixes both ends of the first buffer member 52, and the cap 72 is closed by the stopper 74. Since it is suppressed to flow in the radial direction of the first buffer member 52 is to suppress the contact with the primary scalpel 10.

이로써, 프라이머리 메스(10)가 회전될 때에 제1완충부재(52)와 프라이머리 메스(10) 사이의 간섭에 의해 발생되는 진동 및 소음을 억제할 수 있게 된다.As a result, when the primary scalpel 10 is rotated, it is possible to suppress vibrations and noises generated by the interference between the first buffer member 52 and the primary scalpel 10.

캡(72)은 제1완충부재(52)가 삽입되는 홈부를 이루고 제1완충부재(52)와 프라이머리 메스(10) 사이에 배치되는 제1가이드(77)와, 제1완충부재(52)가 삽입되는 홈부를 이루고 제1완충부재(52)와 구동 플레이트(30) 사이에 배치되는 제2가이드(76)와, 스토퍼(74)에 연결되는 유동방지부를 포함한다.The cap 72 forms a groove portion into which the first buffer member 52 is inserted, and is arranged between the first buffer member 52 and the primary scalpel 10, and the first buffer member 52. ) Includes a second guide 76 disposed between the first buffer member 52 and the driving plate 30 and a flow preventing part connected to the stopper 74.

제1가이드(77)는 프라이머리 메스(10)의 반경 방향으로 경사지게 형성되므로 프라이머리 메스(10)가 회전되어 발생되는 원심력에 의해 제1완충부재(52)가 반경 방향으로 절곡되면 제1완충부재(52)가 제1가이드(77) 내벽에 접촉되어 제1완충부재(52)와 프라이머리 메스(10)가 간섭되는 것을 방지한다.Since the first guide 77 is formed to be inclined in the radial direction of the primary scalpel 10, when the first buffer member 52 is bent in the radial direction by the centrifugal force generated by the rotation of the primary scalpel 10, the first cushion 77 is fully cushioned. The member 52 is in contact with the inner wall of the first guide 77 to prevent the first buffer member 52 and the primary scalpel 10 from interfering.

또한, 제2가이드(76)는 프라이머리 메스(10)가 정지된 상태에서 제1완충부재(52)가 제2가이드(76) 내벽에 접촉되는 방향으로 연장되어 제1완충부재(52)와 구동 플레이트(30)가 간섭되는 것을 방지한다.In addition, the second guide 76 extends in a direction in which the first shock absorbing member 52 contacts the inner wall of the second guide 76 in a state where the primary scalpel 10 is stopped, and thus the first shock absorbing member 52 is separated from the first shock absorbing member 52. The drive plate 30 is prevented from interfering.

따라서 엔진의 구동에 의해 프라이머리 메스(10)의 회전 속도가 급격히 증가되는 경우에 제1완충부재(52)는 프라이머리 메스(10)의 반경 방향으로 곡선을 이루도록 절곡되어 커버 플레이트(20)로부터 구동 플레이트(30)로 전달되는 원주 방향의 회전력을 전달함과 동시에 완충작동을 행하게 된다.Therefore, when the rotational speed of the primary scalpel 10 is drastically increased by driving of the engine, the first shock absorbing member 52 is bent to form a curve in the radial direction of the primary scalpel 10 from the cover plate 20. The shock absorbing operation is performed while transmitting the rotational force in the circumferential direction transmitted to the drive plate 30.

이때, 제1완충부재(52)는 제1가이드(77)의 내벽에 밀착되므로 제1완충부재(52)가 프라이머리 메스(10)의 내벽과 간섭되는 것을 방지하여 구동 중에 프라이머리 메스(10)와 제1완충부재(52) 사이의 접촉에 의해 발생되는 소음 및 진동을 저감시키게 된다.At this time, since the first buffer member 52 is in close contact with the inner wall of the first guide 77, the first buffer member 52 is prevented from interfering with the inner wall of the primary scalpel 10. ) And the noise generated by the contact between the first buffer member 52 and vibration is reduced.

제2가이드(76)는 엔진의 구동에 의해 프라이머리 메스(10)의 반경 방향으로 절곡되었던 제1완충부재(52)가 엔진의 회전력이 저감될 때에 원상태로 복원되면서 구동 플레이트(30)와 간섭되는 것을 방지한다.The second guide 76 interferes with the driving plate 30 while the first shock absorbing member 52, which was bent in the radial direction of the primary scalpel 10 by the driving of the engine, is restored to its original state when the rotational force of the engine is reduced. Prevent it.

물론, 엔진의 회전력이 저감되면서 발생되는 소음 및 진동은 엔진의 회전력이 증가되면서 발생되는 소음 및 진동과 비교하여 미세하기 때문에 제2가이드(76)의 생략이 가능하며, 이러한 변경은 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 구체적인 도면이나 설명은 생략하기로 한다.Of course, since the noise and vibration generated while the rotational force of the engine is reduced are fine compared to the noise and vibration generated as the rotational force of the engine is increased, the second guide 76 may be omitted, and such a change may be omitted. Since it can be easily changed and implemented by those skilled in the art having recognized the configuration will be omitted the specific drawings and description.

유동방지부는 캡(72)의 단부에 구비되고 스토퍼(74)에 연결되는 걸림돌기(78)를 포함한다.The flow preventing part includes a catching protrusion 78 provided at an end of the cap 72 and connected to the stopper 74.

또한, 스토퍼(74)는 제1완충부재(52) 사이에 개재되는 패널 모양으로 형성되고, 캡(72)의 걸림돌기(78)가 삽입되는 홈부(74a)가 양단부에 형성되어 프라이머리 메스(10)의 테두리 측에 리벳과 같은 체결부재로 결합된다.In addition, the stopper 74 is formed in the shape of a panel interposed between the first buffer member 52, the groove portion (74a) is inserted into the both ends of the engaging projection 78 of the cap 72 is formed in the primary scalpel ( 10) is coupled to a fastening member such as a rivet on the edge side.

따라서 프라이머리 메스(10)가 회전되면 스토퍼(74)가 회전되면서 제1탄성부재(52)의 일측 단부를 가압하게 되므로 동력전달을 행하고, 홈부(74a)에 삽입된 걸림돌기(78)가 반경 방향으로 유동되는 것이 억제되므로 제1탄성부재(52)와 프라이머리 메스(10)가 간섭되는 것을 억제하게 된다.Therefore, when the primary scalpel 10 is rotated, the stopper 74 is rotated to press one end of the first elastic member 52 to perform power transmission, and the locking protrusion 78 inserted into the groove portion 74a has a radius. Since the flow in the direction is suppressed, the first elastic member 52 and the primary scalpel 10 are prevented from interfering.

구동 플레이트(30)는 커버 플레이트(20)와 비교하여 작은 환형으로 이루어지고, 외측 테두리에 가압돌기(32)가 형성되며, 이 가압돌기(32)는 제1완충부재(52) 사이에 배치된다.The drive plate 30 has a smaller annular shape compared to the cover plate 20, and a pressing protrusion 32 is formed at an outer edge thereof, and the pressing protrusion 32 is disposed between the first buffer members 52. .

따라서 프라이머리 메스(10)와 동시에 회전되는 커버 플레이트(20)가 제1완충부재(52)의 일측 단부를 가압하여 제1완충부재(52)가 회전되면, 제1완충부재(52)의 타측 단부가 가압돌기(32)를 밀어 구동 플레이트(30)를 회전시키고, 구동 플레이트(30)와 연결된 세컨더리 메스(40)가 회전되면서 동력 전달이 이루어지게 된다.Therefore, when the first shock absorbing member 52 is rotated by pressing the one end of the first shock absorbing member 52 with the cover plate 20 which is simultaneously rotated with the primary scalpel 10, the other side of the first shock absorbing member 52 is removed. The end pushes the pressing protrusion 32 to rotate the driving plate 30, and the secondary scalpel 40 connected to the driving plate 30 rotates to transmit power.

이때, 커버 플레이트(20)에 의해 제1완충부재(52)의 일측 단부가 가압되면 제1완충부재(52)는 압축이 이루어지고, 제1완충부재(52)의 압축이 어느 정도 진행된 후에는 제1완충부재(52)의 타측 단부가 구동 플레이트(30)의 가압돌기(32)를 밀어 동력 전달이 이루어지게 된다.At this time, when one end portion of the first buffer member 52 is pressed by the cover plate 20, the first buffer member 52 is compressed, and after the compression of the first buffer member 52 is performed to some extent, The other end of the first buffer member 52 pushes the pressing protrusion 32 of the driving plate 30 to transmit power.

따라서 동력 전달이 개시된 초기에 발생되는 충격이 제1완충부재(52)에 의해 흡수되므로 동력 전달 초기에 발생되는 진동 및 소음을 저감시킬 수 있게 된다.Therefore, since the shock generated at the beginning of power transmission is absorbed by the first buffer member 52, it is possible to reduce vibration and noise generated at the beginning of power transmission.

커버 플레이트(20)는 제1완충부재(52)의 일측을 가압하는 제1가압부(24)와, 제2완충부재(54)의 일측을 가압하는 제2가압부(26)를 포함한다.The cover plate 20 includes a first pressing part 24 for pressing one side of the first buffer member 52 and a second pressing part 26 for pressing one side of the second buffer member 54.

제1가압부(24)는 환형의 패널 모양의 커버 플레이트(20) 중의 일부분이 하측 방향으로 절곡되어 이루어지고, 제1완충부재(52)에 대향되는 양측 단부에 캡(72)의 걸림돌기(78)가 삽입되는 고정홈부(28)가 형성된다.The first pressing part 24 is formed by bending a portion of the annular panel-shaped cover plate 20 downward, and engaging protrusions of the cap 72 at both end portions facing the first buffer member 52. Fixing groove portion 28 is inserted is formed 78.

따라서 제1완충부재(52)의 양단부에 삽입되는 캡(72)이 제1가압부(24)의 고정홈부(28)에 삽입되므로 동력 전달이 이루어짐과 동시에 제1완충부재(52)가 프라이머리 메스(10)의 반경 방향으로 유동되는 것이 방지된다.Accordingly, since the cap 72 inserted into both ends of the first buffer member 52 is inserted into the fixing groove 28 of the first pressing unit 24, power transmission is performed and at the same time, the first buffer member 52 is primary. The radial flow of the scalpel 10 is prevented.

여기서, 제1가압부(24)는 캡(72)의 상부를 가압하게 되고, 스토퍼(74)가 캡(72)의 하부를 가압하게 되므로 제1완충부재(52)는 제1가압부(24)와 스토퍼(74)의 회전력이 동시에 전달되어 동력전달이 이루어진다.Here, since the first pressing part 24 presses the upper portion of the cap 72, and the stopper 74 presses the lower portion of the cap 72, the first shock absorbing member 52 has the first pressing portion 24. And the rotational force of the stopper 74 are simultaneously transmitted to achieve power transmission.

또한, 제1완충부재(52)에 삽입되는 캡(72)의 걸림돌기(78)는 수직 방향으로 길게 형성되어 걸림돌기(78)의 상부측 일부분이 제1가압부(24)의 고정홈부(28)에 삽입되고, 걸림돌기(78)의 하부측 일부분이 스토퍼(74)의 홈부(74a)에 삽입되므로 캡(72) 및 제1완충부재(52)가 반경 방향으로 유동되는 것을 고정홈부(28)와 홈부(74a)에 의해 효과적으로 억제할 수 있게 된다.In addition, the locking projection 78 of the cap 72 inserted into the first buffer member 52 is formed long in the vertical direction so that a portion of the upper side of the locking projection 78 is the fixing groove portion of the first pressing portion 24 ( 28 and the lower portion of the locking projection 78 is inserted into the groove portion 74a of the stopper 74, so that the cap 72 and the first buffer member 52 flow in the radial direction. 28 and the groove portion 74a can be effectively suppressed.

물론, 캡(72)의 단부에 걸림돌기(78)가 아닌 걸림홈부가 형성되고, 제1가압부(24)와 스토퍼(74)에 돌기가 형성되어 캡(72)의 걸림홈부에 삽입되어도 상기한 바와 같은 작동이 이루어짐을 알 수 있으며, 이는 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 다른 실시예에 대한 구체적인 도면이나 설명을 생략하기로 한다.Of course, a locking groove portion other than the locking projection 78 is formed at the end of the cap 72, and protrusions are formed on the first pressing portion 24 and the stopper 74 to insert the locking groove portion of the cap 72. As it can be seen that the operation is made, which can be easily changed and implemented by those skilled in the art with the technical configuration of the present invention will be omitted the specific drawings or description of the other embodiments.

또한, 환형상의 커버 플레이트(20) 내측 테두리에는 소정 간격을 유지토록 다수 개의 제2가압부(26)가 형성되어 구동 플레이트(30)에 설치되는 제2완충부재(54)를 가압하게 된다.In addition, a plurality of second pressing parts 26 are formed on the inner edge of the annular cover plate 20 to press the second buffer member 54 installed on the driving plate 30.

구동 플레이트(30)에는 다수 개의 장착홀부(34)가 소정 간격을 유지토록 형성되고, 이 장착홀부(34)에 제2완충부재(54)가 삽입되며, 제2가압부(26)와 제2완충부재(54)는 소정 간격을 유지토록 배치된다.A plurality of mounting holes 34 are formed in the driving plate 30 so as to maintain a predetermined interval, and the second shock absorbing member 54 is inserted into the mounting holes 34, and the second press part 26 and the second The buffer member 54 is disposed to maintain a predetermined interval.

이로써, 프라이머리 메스(10)의 회전 속도가 급격히 증가하거나 세컨더리 메스(40)의 속도가 급격히 감소되어 커버 플레이트(20)와 구동 플레이트(30)의 충돌이 발생되는 경우에는 제1완충부재(52)에 의해 1차 완충작동이 이루어진다.As a result, when the rotational speed of the primary scalpel 10 rapidly increases or the speed of the secondary scalpel 40 decreases rapidly, a collision between the cover plate 20 and the driving plate 30 occurs. The primary buffering operation is performed by

이때, 제1완충부재(52)의 압축이 지속되어 제1완충부재(52)가 소정치 이상으로 압축되면 제2가압부(26)가 제2완충부재(54)를 가압하여 제2완충부재(54)의 압축이 발생되면서 2차 완충작동이 이루어지게 된다.At this time, when the compression of the first buffer member 52 is continued and the first buffer member 52 is compressed to a predetermined value or more, the second pressurizing portion 26 presses the second buffer member 54 to press the second buffer member. As the compression of 54 occurs, the secondary buffer operation is performed.

제2완충부재(54)는 구동 플레이트(30)의 장착홀부(34)에 삽입되는 기둥 모양으로 형성되고, 탄성재질로 이루어지므로 커버 플레이트(20)의 제2가압부(26)에 의해 외력이 가해지면 압축되면서 완충작동을 행하게 된다.The second buffer member 54 is formed in a column shape inserted into the mounting hole part 34 of the driving plate 30, and is made of an elastic material, so that the external force is applied by the second pressing part 26 of the cover plate 20. When applied, it compresses and performs a cushioning operation.

마감부(90)는 제2완충부재(54)와 장착홀부(34) 사이에 개재되는 마감패널(92)을 포함하므로 제2가압부(26)에 의해 제2완충부재(54)가 압축될 때에 금속재질의 제2가압부(26)에 의해 탄성재질의 제2완충부재(54)가 손상되는 것을 억제할 수 있게 된다.Since the finishing part 90 includes a finishing panel 92 interposed between the second shock absorbing member 54 and the mounting hole 34, the second shock absorbing member 54 may be compressed by the second pressing part 26. At this time, it is possible to suppress the damage of the second cushioning member 54 made of the elastic material by the second pressing part 26 made of metal.

물론, 마감패널(92)은 제2완충부재(54)와 구동 플레이트(30)의 장착홀부(34)가 접촉되는 것도 억제하므로 구동 플레이트(30)에 의해 제2완충부재(54)가 손상되는 것을 억제할 수 있게 된다.Of course, since the closing panel 92 also suppresses contact between the second buffering member 54 and the mounting hole 34 of the driving plate 30, the second shock absorbing member 54 is damaged by the driving plate 30. Can be suppressed.

이러한 마감패널(92)은 금속재질로 이루어지는 것이 바람직하다.The finishing panel 92 is preferably made of a metal material.

또한, 마감패널(92)에는 안착홈부(92a)가 형성되고, 제2완충부재(54)에는 안착홈부(92a)가 끼워지는 삽입홀부(54a)가 형성되며, 장착홀부(34)에는 안착홈부(92a)에 삽입되는 안착돌기(34a)가 형성된다.In addition, a seating recess 92a is formed in the closing panel 92, an insertion hole 54a into which the seating recess 92a is fitted is formed in the second buffer member 54, and a seating recess 34 in the mounting hole 34. The mounting protrusion 34a inserted into the 92a is formed.

따라서 제2완충부재(54)의 양단부에 형성된 삽입홀부(54a)에 각각 마감패널(92)의 안착홀부(92a)를 끼우면 제2완충부재(54)와 마감패널(92)의 결합이 이루어진다.Therefore, when the seating hole portions 92a of the closing panel 92 are inserted into the insertion hole portions 54a formed at both ends of the second buffering member 54, the second buffering member 54 and the closing panel 92 are coupled to each other.

이후에, 제2완충부재(54)를 압축시켜 장착홀부(34)에 삽입하면 제2완충부재(54)가 원상태로 복원되면서 안착돌기(34a)가 안착홈부(92a)에 삽입되어 제2완충부재(54)와 구동 플레이트(30)의 결합이 이루어지게 된다.Subsequently, when the second shock absorbing member 54 is compressed and inserted into the mounting hole 34, the second shock absorbing member 54 is restored to its original state, and the seating protrusion 34a is inserted into the seating recess 92a to thereby secure the second shock absorbing member 54. Joining of the member 54 and the drive plate 30 is made.

또한, 마감패널(92)에는 제2완충부재(54)와 장착홀부(34) 사이로 절곡되는 커버부(92b)가 형성되므로 제2완충부재(54)의 측면과 구동 플레이트(30)의 장착홀부(34)가 접촉되는 것을 억제할 수 있게 된다.In addition, the closing panel 92 is formed with a cover 92b that is bent between the second buffering member 54 and the mounting hole 34, so that the side of the second buffering member 54 and the mounting hole of the driving plate 30 are formed. The contact of the 34 can be suppressed.

커버부(92b)는 구동 플레이트(30)의 테두리 측에 배치되므로 구동 플레이트(30)가 회전될 때에 원심력에 의해 외측 방향으로 이동되는 제2완충부재(54)가 장착홀부(34)와 접촉되면서 손상되는 것을 억제토록 한다.Since the cover portion 92b is disposed at the edge of the drive plate 30, the second buffer member 54, which is moved outward by the centrifugal force when the drive plate 30 is rotated, comes into contact with the mounting hole 34. To prevent damage.

물론, 커버부(92b)는 복수개가 형성될 수 있고, 복수개의 커버부(92b)가 형성되면 제2완충부재(54)의 일측면과 장착홀부(34) 사이에 커버부(92b)가 개재되며, 제2완충부재(34)의 타측면과 장착홀부(34) 사이에도 커버부(92b)가 개재된다.Of course, a plurality of cover parts 92b may be formed, and when a plurality of cover parts 92b are formed, a cover part 92b is interposed between one side surface of the second buffer member 54 and the mounting hole part 34. The cover 92b is interposed between the other side surface of the second buffer member 34 and the mounting hole 34.

이는 본 발명의 기술구성을 인지한 당업자가 용이하게 변경하여 실시할 수 있는 것이므로 다른 실시예에 대한 구체적인 도면이나 설명은 생략하기로 한다.This can be easily changed and implemented by those skilled in the art having recognized the technical configuration of the present invention will not be described in detail drawings or description of other embodiments.

상기와 같이 구성된 본 발명의 일 실시예에 따른 듀얼 메스 플라이휠의 작용을 살펴보면 다음과 같다.Looking at the operation of the dual scalpel flywheel according to an embodiment of the present invention configured as described above are as follows.

먼저, 엔진이 구동되면 프라이머리 메스(10)가 회전되면서 커버 플레이트(20)의 회전이 이루어지고, 스토퍼(74) 및 커버 플레이트(20)의 제1가압부(24)에 밀착되게 배치되는 제1완충부재(52)가 소정치 이상 압축된 후에 구동 플레이트(30)의 가압돌기(32)를 밀어 구동 플레이트(30)의 회전이 이루어지게 된다.First, when the engine is driven, as the primary scalpel 10 is rotated, rotation of the cover plate 20 is performed, and is disposed in close contact with the stopper 74 and the first pressing part 24 of the cover plate 20. After the shock absorbing member 52 is compressed to a predetermined value or more, the pressing protrusion 32 of the driving plate 30 is pushed to rotate the driving plate 30.

이렇게 구동 플레이트(30)가 회전되면 연결부재(86)에 의해 연결된 세컨더리 메스(40)가 회전하게 되므로 변속기에 동력 전달이 이루어지게 된다.When the driving plate 30 is rotated as described above, the secondary scalpel 40 connected by the connecting member 86 rotates, thereby transmitting power to the transmission.

상기한 바와 같이 동력 전달이 이루어지게 되면 프라이머리 메스(10)의 회전에 의해 원심력이 발생되는데, 제1완충부재(52)는 양측 단부에 캡(72)이 삽입되고, 이 캡(72)은 스토퍼(74)의 홈부(74a) 및 제1가압부(24)의 고정홈부(28)에 의해 반경 방향의 유동이 억제되므로 제1완충부재(52)와 프라이머리 메스(10)가 접촉되는 것이 방지된다.When the power transmission is made as described above, the centrifugal force is generated by the rotation of the primary scalpel 10, the first buffer member 52, the cap 72 is inserted at both ends, the cap 72 is Since the flow in the radial direction is suppressed by the groove portion 74a of the stopper 74 and the fixing groove portion 28 of the first pressing portion 24, the first buffer member 52 and the primary scalpel 10 come into contact with each other. Is prevented.

프라이머리 메스(10)의 회전에 의해 발생되는 원심력에 의해 제1완충부재(52)는 곡선 형상을 이루며 반경 방향으로 절곡되고, 캡(72)의 제1가이드(77) 내벽에 밀착되므로 제1완충부재(52)와 프라이머리 메스(10)가 접촉되는 것이 억제된다.Due to the centrifugal force generated by the rotation of the primary scalpel 10, the first buffer member 52 is curved in a radial direction and is in close contact with an inner wall of the first guide 77 of the cap 72. Contact between the buffer member 52 and the primary scalpel 10 is suppressed.

이로써, 프라이머리 메스(10)와 제1완충부재(52)가 간섭되어 발생되는 소음 및 진동을 저감시킬 수 있게 되므로 조용하고 안정된 동력 전달을 행할 수 있게 된다.As a result, the noise and vibration generated by the interference between the primary scalpel 10 and the first shock absorbing member 52 can be reduced, thereby enabling quiet and stable power transmission.

또한, 정지 상태에서 동력 전달이 개시되거나 동력 전달 진행 중에 급격한 변속이 이루어지면 커버 플레이트(20)와 구동 플레이트(30) 사이에 충돌이 발생되는데, 제1완충부재(52)의 압축에 의해 1차 완충작동이 이루어지고, 제1완충부재(52)가 소정치 이상 압축되면 제2가압부(26)가 제2완충부재(54)를 가압하게 되므로 제2완충부재(54)의 압축에 의해 2차 완충작동이 이루어지게 된다.In addition, when the transmission of power is started in a stationary state or a sudden shift is made during the transmission of power, a collision occurs between the cover plate 20 and the driving plate 30. When the shock absorbing operation is made, and the first buffering member 52 is compressed by a predetermined value or more, the second pressing unit 26 presses the second buffering member 54, thereby compressing the second buffering member 54. Car shock absorbing operation is made.

제2가압부(26)에 의해 압축되는 제2완충부재(54)는 마감패널(92)에 의해 제2가압부(26)와 접촉되지 않으므로 탄성재질의 제2완충부재(54)가 금속재질의 제2가압부(26)에 의해 손상되는 것을 방지할 수 있다.Since the second shock absorbing member 54 compressed by the second pressing part 26 is not in contact with the second pressing part 26 by the finishing panel 92, the second shock absorbing member 54 of the elastic material is made of metal. Can be prevented from being damaged by the second pressing portion 26.

또한, 마감패널(92)로부터 절곡되게 연장되는 커버부(92b)에 의해 제2완충부재(54)의 측면이 장착홀부(34)와 접촉되는 것을 억제하므로 구동 플레이트(30)가 회전되면서 발생되는 원심력에 의해 제2완충부재(54)가 구동 플레이트(30)의 외측 방향으로 이동되어 장착홀부(34)에 의해 손상되는 것을 방지할 수 있다.In addition, since the side of the second buffer member 54 is prevented from contacting the mounting hole portion 34 by the cover portion 92b extending from the finish panel 92, the driving plate 30 is rotated. By the centrifugal force, the second buffer member 54 may be moved outwardly of the driving plate 30 to prevent damage by the mounting hole 34.

이로써, 구동 중에 발생되는 부품들 사이의 간섭을 방지할 수 있고, 효과적인 완충작동을 행하는 듀얼 메스 플라이휠을 제공할 수 있게 된다.As a result, it is possible to prevent the interference between the components generated during the driving, and to provide a dual scalpel flywheel that performs an effective cushioning operation.

Will understand.

또한, 차량에 설치되는 듀얼 메스 플라이휠을 예로 들어 설명하였으나, 이는 예시적인 것에 불과하며, 차량에 사용되는 듀얼 메스 플라이휠이 아닌 다른 제품에도 본 발명의 듀얼 메스 플라이휠이 사용될 수 있다.In addition, the dual scalpel flywheel installed in the vehicle has been described as an example, but this is merely illustrative, the dual scalpel flywheel of the present invention can be used in other products than the dual scalpel flywheel used in the vehicle.

따라서 본 발명의 진정한 기술적 보호범위는 아래의 특허청구범위에 의해서 정하여져야 할 것이다.Therefore, the true technical protection scope of the present invention will be defined by the claims below.
