본 고안은 자동차 동력전달 시스템의 동력전달축에 대한 비틀림 진동 흡수 수단에 관한 것으로서, 특히 변속기로부터 연장되어지는 동력출력축에 설치되는 비틀림 진동흡수 댐퍼에 관한 것이다.The present invention relates to a torsional vibration absorbing means for a power transmission shaft of an automobile power transmission system, and more particularly to a torsional vibration absorption damper installed on a power output shaft extending from the transmission.
크랭크축으로 부터 생성되는 구동토크의 변동은 플라이 휘일을 크랭크축의 끝단부에 고정시킴으로써 평형을 유지할 수 있고, 다기통 엔진의 길이에 의해 크랭크축의 강성은 충분히 크게 유지되지만 각 크랭크 핀 상호간이나 각 크랭크 핀과 플라이 휘일사이에 생기는 탄성은 무시하여 제외시킬 수는 없게 되며, 또한 엔진으로 부터 구동토크를 받아 회전하는 동력전달축에 클러치나 변속기를 거치면서 급격히 변화하는 회전력이 가해짐으로써 크랭크축 또는 동력전달축에 비틀림과 굽힘에 의한 순간적인 변형이 일어나게 되고 그 다음 다시 원위치로 회복되는 과정에서 진동이 발생하게 된다. 이러한 진동은 동력전달 시스템에 있어서 동력전달 진행방향으로 연속하여 발생되기 때문에 공진하게 되고, 최초 크랭크축이 소정의 회전속도(예를들어, 150~2700rpm)가 되면 고유진동수와 더불어 최대의 공진주파수 값을 갖는 최대 공진현상을 일으켜 동력전달축에는 매우 복잡한 비틀림진동(torsional vibration)을 일으키며 이에 의해 승차감을 해치거나 과다한 소음발생 및 차체의 수명을 격감 시키는 문제점을 야기시키게 된다.The variation of the drive torque generated from the crankshaft can be balanced by fixing the flywheel to the end of the crankshaft, and the rigidity of the crankshaft is maintained sufficiently by the length of the multi-cylinder engine, but each crank pin is mutually different or each crank pin The elasticity between the flywheel and the flywheel cannot be ignored, and the crankshaft or power transmission is applied by applying a rapidly changing rotational force through a clutch or transmission to the rotating power transmission shaft that receives the driving torque from the engine. Torsion and bending of the shaft cause instantaneous deformation and then vibration in the process of returning to its original position. These vibrations are resonant because they are continuously generated in the power transmission progression in the power transmission system. When the initial crankshaft reaches a predetermined rotational speed (for example, 150 to 2700 rpm), the maximum resonance frequency value as well as the natural frequency is reached. It causes maximum resonant phenomena, which causes very complex torsional vibrations in the power transmission shaft, thereby causing a problem of impairing ride comfort, excessive noise, and reducing the life of the vehicle body.
따라서, 본 고안은 전술한 바와 같은 문제점을 감안하여 안출한 것으로서, 동력전달축의 일정 위치에 끼워 설치하여 비틀림 진동을 흡수할 수 있도록 한 비틀림 진동흡수 댐퍼를 제공하는 것을 그 목적으로 한다.Accordingly, an object of the present invention is to provide a torsional vibration absorption damper which is designed to absorb the torsional vibration by inserting it into a predetermined position of the power transmission shaft.
본 고안에 다른 비틀림 진동흡수 댐퍼는 변속기로 부터 연장되어 나오는 동력전달축과 추진축의 연결부 플랜지 외측의 축끼움 구멍부 둘레로 삽입되어 결합하고, 금속재료의 판재를 중공의 반원통 형태로 형성한 후 중앙 바닥부에 플랜지의 축끼움 구멍부와 동일 형상의 축끼움 구멍부를 형성하고 외측면 둘레를 따라 일정한 두께 및 폭크기를 갖는 고무재질의 제1원형링을 부착 설치하고 제1원형링 위로 연속하여 제1원형링과 동일한 두께 및 폭크기를 갖는 금속재의 제2원형링을 부착 설치하여 구성한 것을 특징으로 한다.The torsional vibration absorption damper according to the present invention is inserted into and coupled around the shaft fitting hole outside the connecting flange of the power transmission shaft and the propulsion shaft extending from the transmission, and the plate of the metal material is formed into a hollow semi-cylindrical shape. At the bottom of the center, form a shaft fitting hole having the same shape as the flange fitting hole of the flange, and attach and install a rubber-shaped first circular ring having a constant thickness and width along the outer surface and continuously over the first circular ring. A second circular ring of metal material having the same thickness and width as the first circular ring is attached and configured.
이하, 본 고안을 첨부도면을 참조로 하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.
제1도 및 제2도에 도시한 바와 같이, 본 고안의 비틀림 진동흡수댐퍼(1)는 금속재의 판재를 중공의 반원통 형상으로 형성하고, 중앙바닥부(9)에 플랜지(2)의 축끼움 구멍부 형상과 동일하게 축끼움 구멍부(6)를 관통시켜 구성하며, 외측둘레의 폭두께부분 외측면을 따라 고무재질의 일정두께 및 폭크기를 갖는 제1원형링(3)을 적합한 부착수단을 통해 압착 설치하고, 제1원형링(3) 위로 연속하여 제1원형링(3)과 동일한 두께 및 폭크기를 갖는 금속재의 제2원형링(4)을 압착 설치하여 이루어진다. 재질이 상이한 두개의 원형링(3)(4)을 연속하여 압착 설치함으로써 진동흡수에 필요한 중량감 및 회전 유연성을 적합하게 조화시켜 비틀림 진동을 효과적으로 흡수할 수 있도록 해준다.As shown in FIG. 1 and FIG. 2, the torsional vibration absorption damper 1 of the present invention forms a plate of metal in a hollow semi-cylindrical shape, and the shaft of the flange 2 is formed on the central bottom 9. It is configured to pass through the shaft fitting hole 6 in the same way as the shape of the fitting hole, and appropriately attaches the first circular ring 3 having a predetermined thickness and width of the rubber material along the outer surface of the width thickness portion of the outer circumference. It is made by press-fitting by means, and press-fitting the second circular ring (4) of metal material having the same thickness and width as the first circular ring (3) continuously on the first circular ring (3). Compression and installation of two circular rings (3) (4) of different materials in succession makes it possible to effectively absorb torsional vibrations by properly matching the weight and rotational flexibility required for vibration absorption.
이와 같은 형태의 비틀림 진동흡수 댐퍼(1)를 제3도에 도시한 바와 같이 먼저 플랜지(2) 외측면에서 플랜지(2)의 축끼움 구멍부 형상을 일치하여 정렬시켜 동력전달축(5)에 끼워 배치하고, 비틀림 진동흡수 댐퍼(1)를 소정각도로 회전 이동시켜 플랜지(2)의 다수개 볼트 체결구멍과 비틀림 진동흡수댐퍼(1)의 볼트 체결구멍들을 정렬시킨 후, 플랜지(2)의 내측면에 설치되는 고무재질의 커플링(7)과 일체로 하여 볼트 너트 결합방식으로 체결하여 배치한다.As shown in FIG. 3, the torsional vibration absorption damper 1 of this type is aligned with the shape of the axial fitting hole of the flange 2 on the outer surface of the flange 2, and then, the power transmission shaft 5 is aligned. And the torsional vibration absorption damper 1 is rotated at a predetermined angle to align the bolting holes of the torsional vibration absorption damper 1 with the bolt coupling holes of the torsional vibration absorption damper 1. Integral with the rubber material coupling 7 installed on the inner side is arranged by fastening the bolt nut coupling method.
동력전달축(5)은 비틀림 진동흡수 댐퍼(1)와 플랜지(2)의 중앙바닥부(9)에 형성된 축끼움 구멍부(6)에 끼워져 커플링(7)을 너트로써 일체로 체결시킨 후 연속하여 추진축(8)과 연결되어 동력을 전달하게 된다.The power transmission shaft 5 is fitted to the torsional vibration absorption damper 1 and the shaft fitting hole 6 formed in the center bottom portion 9 of the flange 2 to integrally fasten the coupling 7 with a nut. It is continuously connected to the propulsion shaft 8 to transmit power.
이상과 같은 구성과 배치결합 상태로 설치되는 본 고안의 비틀림 진동흡수 댐퍼(1)에 의해서, 동력전달축(5)에 엔진으로 부터의 구동력 변화에 따라 급격히 변화하는 회전력이 가해져 비틀림과 굽힘에 의한 순간적인 변형이 생성되며 비틀림 진동을 일으키려고 해도 비틀림 진동흡수 댐퍼(1)의 제2원형링(4)이 자체의 질량과 관성에 의해 일정속도의 회전을 계속하려고 하는 반작용력을 발생시켜 상기 비틀림진동과 상반되는 변위를 일으키게 되는 것이고, 이에 따라 동력전달축(5)의 비틀림 진동은 상기 제2원형링(4)의 관성에 의한 변위에 의하여 감쇠되게 된다.By the torsional vibration absorption damper (1) of the present invention installed in the configuration and arrangement as described above, the rotational force that is rapidly changed in accordance with the change of the driving force from the engine is applied to the power transmission shaft (5) by torsion and bending The instantaneous deformation is generated and the second circular ring 4 of the torsional vibration absorption damper 1 generates a reaction force that tries to continue to rotate at a constant speed by its mass and inertia, even if it tries to cause torsional vibration. The displacement opposite to the vibration is caused, so that the torsional vibration of the power transmission shaft 5 is attenuated by the displacement caused by the inertia of the second circular ring 4.
상기 제2원형링(4)의 변위량은 제2원형링(4)의 내측에 압착된 제1원형링(4)의 탄성력에 의해서 결정되어 지는 것이며, 이 제1원형링(3)은 탄성력이 양호한 고무재질로 형성시키되 제2원형링(4)의 변위량이 최대 ±0.2°의 범위내로 제한하여 동력전달축(5)의 급격한 회전수가감에 의한 비틀림진동의 발생을 경감시킬 수 있게 되는 것이다.The displacement amount of the second circular ring 4 is determined by the elastic force of the first circular ring 4 pressed inside the second circular ring 4, and the first circular ring 3 has an elastic force. It is formed of a good rubber material, but the displacement amount of the second circular ring 4 is limited to within a range of up to ± 0.2 ° to reduce the occurrence of torsional vibration due to the sudden rotational speed of the power transmission shaft (5).
이상 설명한 바와 같이 본 고안의 진동흡수 댐퍼는 동력전달축에서 발생하는 비틀림 진동에 대하여 제2원형링이 상반되는 변위를 일으키게 됨으로써 상기 동력전달축의 비틀림진동을 충분히 흡수하여 크랭크축의 소정의 회전속도(예를들어, 2700rpm)에서 발생되는 최대공진 주파수 값을 급격히 감소시키고, 이에 의해, 승차감을 향상시키며 과다한 소음발생 및 차체 주요구성부의 마모와 차체 수명의 단축을 개선시키는 효과를 나타낸다.As described above, the vibration absorption damper of the present invention causes the second circular ring to be displaced to the torsional vibration generated by the power transmission shaft, thereby sufficiently absorbing the torsional vibration of the power transmission shaft, thereby providing a predetermined rotational speed of the crankshaft (eg, For example, the maximum resonant frequency value generated at 2700 rpm) is drastically reduced, thereby improving riding comfort, producing excessive noise, and improving wear and tear of main body parts and shortening of vehicle life.
