The primary mass 311 and the secondary mass 312 can rotate relative to the relative side to a limited range and drive torque means acting between the flywheel masses to gradually retard the relative rotation of the flywheel mass as the torque increases. That is, at low torque levels the flywheel mass does not rotate significantly relative to the other side but at high torque levels At the same engine speed, the flywheel mass rotates significantly relative to the mating side. Such drive torque means may be springs or other vibration damping means. The vibration damping device is also provided to eliminate vibrations that appear during relative rotation between the flywheel masses. In the conventional vibration damping flywheel structure, as shown in FIG. 3, the mass of the flywheel is divided into a primary mass 311 and a secondary mass 312 so that the secondary mass 312 serves as a dynamic damper. The primary mass 311 is fastened by the hub plate 316 and the bolt 323, and the secondary mass 312 is fastened by the combination of the hub plate 316 and the rivet 319. The mass 311 and the secondary mass 312 are connected by a spring, and when the clutch is pressed against the secondary mass 312 and the secondary mass 312 rotates, the spring attached to the primary mass 311 is removed. Word is that structure.

FIG. 1 is a cross-sectional view of a multi-mass vibration damping flywheel according to an embodiment of the present invention, and FIG. 2 is a multi-mass vibration according to an embodiment of the present invention. Assembly of damped flywheel.
도 1 내지 도 2에 도시된 바와 같이, 본 발명의 플라이휠은 엔진의 크랭크축과 연결되는 1차 질량체와 변속기의 입력축과 연결되는 2차 질량체로 구성된다.1 to 2, the flywheel of the present invention is composed of a primary mass connected to the crankshaft of the engine and a secondary mass connected to the input shaft of the transmission.
2차 질량체(12)에는 리벳(21)을 통해 피니언 기어(26)가 장착되며, 볼 베어링(19)으로 지지되어 있다.The secondary mass 12 is mounted with a pinion gear 26 via rivets 21 and supported by a ball bearing 19.
1차 질량체(11)에는 1차 질량체(11)의 외주에서 시작하여 피니언 기어(26)의 일부분까지 덮는 커버(15)가 형성되며, 상기 1차 질량체(11)와 커버(15)사이에는스프링 가이드(24)가 형성된다.The primary mass 11 is formed with a cover 15 starting from the outer periphery of the primary mass 11 and covering a portion of the pinion gear 26, and a spring between the primary mass 11 and the cover 15. Guide 24 is formed.
이 스프링 가이드(24)는 피니언 기어(26)의 일단에 근접하여 형성되고, 대향측 피니언 기어(26)의 일단에도 스프링 가이드(24)가 형성되며, 스프링 가이드(24) 각각에 직선형 스프링(25)이 삽입된다.The spring guide 24 is formed close to one end of the pinion gear 26, a spring guide 24 is also formed at one end of the opposing pinion gear 26, and a straight spring 25 at each of the spring guides 24. ) Is inserted.
스프링 가이드(24)와 피니언 기어(26) 사이에는 피니언 기어(26)의 회전에 따라 좌우로 연동하는 랙 기어(27)가 설치되고, 이 랙 기어(27)의 중앙 부위가 돌출되어 스프링(25) 중앙에 삽입되므로서 랙 기어(27)의 좌우 이동으로 스프링(25)을 가압할 수 있도록 돌출부(28)를 갖는다.Between the spring guide 24 and the pinion gear 26, a rack gear 27 that interlocks from side to side in accordance with the rotation of the pinion gear 26 is installed, and the center portion of the rack gear 27 protrudes to form a spring 25 It is inserted into the center has a projection 28 so as to press the spring 25 by the left and right movement of the rack gear (27).
상기한 스프링(25), 스프링 가이드(24), 일차 질량(11) 및 커버(15)는 레이져 용접을 하여 밀봉한다.The spring 25, the spring guide 24, the primary mass 11 and the cover 15 are sealed by laser welding.
1차 질량체(11)의 중앙에는 허브 플레이트(16)가 볼트(23)로서 고정되는데, 이 허브 플레이트(16)는 2차 질량체(12)가 1차 질량체(11)에 조립될 수 있도록 하는 지지대 기능을 한다.즉, 허브 플레이트(16)의 위로 볼 베어링(19)을 압입한 후 2차 질량체(12)가 다시 압입된다.In the center of the primary mass 11, a hub plate 16 is fixed as a bolt 23, which supports the secondary mass 12 to be assembled to the primary mass 11. That is, after the ball bearing 19 is press-fitted onto the hub plate 16, the secondary mass 12 is press-fitted again.
허브 플레이트(16)의 안쪽으로는 니들 베어링(20)이 압입되어 변속기 입력축 기어의 지지대 역할을 한다.The needle bearing 20 is pressed into the hub plate 16 to serve as a support for the transmission input shaft gear.
전술한 바와 같이 구성된 본 발명의 플라이휠의 작용을 설명하면 다음과 같다.Referring to the operation of the flywheel of the present invention configured as described above are as follows.
엔진의 토오크 변동이 발생하면 1차 질량체(11)의 회전력이 커져서 피니언 기어(26)와의 상대회전이 발생한다.따라서 1차 질량체(11)을 고정으로 보면 피니언 기어(26)는 회전운동이 발생하게 되고 이는 랙 기어(27)를 일측으로 이동시키면서 스프링(25)을 압축시킨다.When the torque fluctuation of the engine occurs, the rotational force of the primary mass 11 becomes large, and a relative rotation with the pinion gear 26 occurs. Therefore, when the primary mass 11 is fixed, the pinion gear 26 generates a rotational motion. This compresses the spring 25 while moving the rack gear 27 to one side.
본 발명에 따른 랙과 피니언을 이용한 플라이휠은 댐퍼를 튜닝시 이상적인 이력 곡선을 용이하게 구현하여 최적의 진동 감쇄효과를 이룰 수 있으며, 엔진의 특성 및 상태에 따라 스프링의 감쇠치를 조절하여 다중 질량 플라이휠의 완충 효과를 구현하는데 필요한 이상적인 토오크 곡선을 용이하게 실현할 수 있다.The flywheel using the rack and pinion according to the present invention can achieve an optimal vibration damping effect by easily implementing the ideal hysteresis curve when tuning the damper, and by adjusting the damping value of the spring according to the characteristics and condition of the engine, It is easy to realize the ideal torque curve required to implement the damping effect.
전술한 바와 같이 본 발명에 따른 랙과 피니언을 이용한 다중 질량 진동 감쇠 플라이휠은 회전하는 피니언 기어와 이와 반대방향으로 회전하면서 스프링을 압축시키는 랙 기어 및 스프링의 조합 작용으로 차량의 래틀 소음과 변속기에서 발생하는 진동 소음을 최적 저감할 수 있으며, 또한 건식으로도 제조가 가능하도록 설계하여 플라이휠의 구성을 단순화시켜 원가를 절감할 수 있다.As described above, the multi-mass vibration damping flywheel using the rack and pinion according to the present invention is generated in a vehicle rattle noise and a transmission by a combination action of a rotating pinion gear and a rack gear and a spring compressing the spring while rotating in the opposite direction. It is possible to reduce vibration noise optimally, and also to be manufactured in a dry manner, thereby simplifying the configuration of the flywheel, thereby reducing the cost.
