Description
본 발명은 FR 자동차에서 트랜스미션(transmission)과 디퍼렌셜 기어(differential gear)를 연결하며, 동력을 전달하는 추진축(propeller shaft)에관한 것으로서, 좀 더 구체적으로는 엔진이 구동되는 상태에서 추진축의 회전 진동이 차체에 전달되는 현상을 방지하기 위한 자동차 추진축의 방진구조에 관한 것이다.The present invention relates to a propeller shaft that transmits power and transmits a transmission and a differential gear in an FR vehicle, and more specifically, rotational vibration of the propulsion shaft in the state in which the engine is driven. The present invention relates to an anti-vibration structure of an automobile propulsion shaft for preventing a phenomenon transmitted to a vehicle body.
도 1은 일반적인 추진축을 나타낸 측면도로서, 일반적으로 추진축(1)은 중공(中空)의 탄소강관을 사용하는 것이 보통이지만, 양 끝에 유니버셜 죠인트(universal joint)(2)가 연결되어 동력 전달시 끊임없이 비틀림 토크(torsion torque)를 받으면서 고속 회전하기 때문에 길이가 긴 추진축(1)은 진동이 심하게 발생되고, 이에 따라 추진축(1)의 중간지점에 설치되는 센터 베어링(3)에는 추진축(1)의 회전에 따라 발생되는 진동 및 소음이 차체측으로 전달되지 않도록 하는 방진장치를 구비하게 된다.FIG. 1 is a side view showing a general propulsion shaft. In general, the propulsion shaft 1 generally uses a hollow carbon steel pipe, but a universal joint 2 is connected at both ends to constantly twist the power. Because of the high speed rotation under torque, the long propulsion shaft 1 vibrates violently, and thus the center bearing 3 installed at the intermediate point of the propulsion shaft 1 is subjected to the rotation of the propulsion shaft 1. It is provided with a vibration isolator to prevent the vibration and noise generated by the transmission to the vehicle body side.
도 2는 종래 추진축의 방진장치를 나타낸 종단면도로서, 2개로 분할 형성된 추진축(1)의 연결지점에 설치되는 센터 베어링(3)은 베어링 브라켓(4)에 의해 차체(5)에 지지되어 있고 상기 베어링 브라켓(4)과 차체(5)사이에는 2개의 방진루버(6)가 보울트(7) 및 너트(8)로 체결되어 있다.FIG. 2 is a longitudinal sectional view showing a dustproof device of a conventional propulsion shaft, in which a center bearing 3 installed at a connection point of two propulsion shafts 1 divided into two is supported on a vehicle body 5 by a bearing bracket 4; Two anti-vibration louvers 6 are fastened by the bolt 7 and the nut 8 between the bearing bracket 4 and the vehicle body 5.
따라서 추진축(1)의 회전시 발생되는 진동 및 소음이 베어링 브라켓(4)과 차체(5)사이에 설치된 방진루버(6)가 차체(5)측으로 전달되지 않도록 차단시키는 역할을 하게 된다.Therefore, the vibration and noise generated during the rotation of the propulsion shaft 1 serve to block the anti-vibration louver 6 installed between the bearing bracket 4 and the vehicle body 5 from being transmitted to the vehicle body 5 side.
그러나 이러한 종래의 장치는 추진축(1)이 워낙 큰 비틀림 토크를 받으면서고속 회전하기 때문에 베어링 브라켓(4)의 양측으로 설치되는 2개의 방진루버(6)로는 차체(5)로 전달되는 진동 및 소음을 차단하는데 한계가 있어 차량의 NVH(Noise Vibration Harshness) 성능이 악화되어 전체적인 차량의 상품성을 저하시키는 요인으로 작용되었다.However, since the propulsion shaft 1 rotates at a high speed while the propulsion shaft 1 receives a large torsional torque, the vibration and noise transmitted to the vehicle body 5 are transmitted to the two anti-vibration louvers 6 installed on both sides of the bearing bracket 4. Due to the limitation of blocking, the vehicle's noise vibration harness (NVH) performance deteriorated, which contributed to the deterioration of the overall vehicle's marketability.
본 발명은 종래의 이와 같은 문제점을 해결하기 위해 안출한 것으로서, 추진축의 회전시 발생되는 진동 및 소음을 흡수하는 방진구조를 2중으로 하여 차체로 전달되지 않도록 하므로 차량의 NVH 성능을 향상시킬 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve such a problem in the prior art, so that the vibration-proof structure that absorbs the vibration and noise generated when the propulsion shaft is rotated so as not to be transmitted to the vehicle body to improve the NVH performance of the vehicle. The purpose is.

이하, 본 발명을 일 실시예로 도시한 도 3을 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, described in more detail with reference to Figure 3 showing the present invention as an embodiment.
도 3은 본 발명의 장치를 나타낸 종단면도로서, 본 발명은 센터 베어링(3)에베어링 브라켓(4)이 고정되어 있고 상기 베어링 브라켓은 별도의 메인 브라켓(9)에 보울트(11) 및 너트(12)로 고정되는데, 이들의 체결부위에는 추진축(1)의 구동에 따라 발생된 진동 및 소음을 1차적으로 흡수하는 제 1 방진루버(10)가 끼워져 있다.Figure 3 is a longitudinal sectional view of the device of the present invention, in which the bearing bracket 4 is fixed to the center bearing 3, and the bearing bracket has a bolt 11 and a nut ( 12), the fastening part 10 is fitted with a first anti-vibration louver 10 that primarily absorbs the vibration and noise generated by the driving of the propulsion shaft (1).
상기 메인 브라켓(9)의 중심부에는 베어링 브라켓(4)과 간섭이 빌생되지 않도록 긴 장공(9a)이 형성되어 있다.The long hole 9a is formed in the center of the main bracket 9 so that interference with the bearing bracket 4 is not generated.
그리고 상기 베어링 브라켓(4)이 지지된 메인 브라켓(9)은 차체(5)에 또 다른 보울트(14) 및 너트(15)로 고정되는데, 이들의 체결부위에는 제 1 방진루버(10)에 의해 흡수되지 않고 차체(5)측으로 전달되는 진동 및 소음을 2차적으로 흡수하는 제 2 방진루버(13)가 끼워져 있다.In addition, the main bracket 9 on which the bearing bracket 4 is supported is fixed to the vehicle body 5 by another bolt 14 and a nut 15, which are fastened by a first anti-vibration louver 10. A second anti-vibration louver 13, which absorbs vibration and noise transmitted to the vehicle body 5 side without being absorbed, is fitted.
이와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above is as follows.
먼저, 엔진의 구동으로 추진축(1)이 비틀림 토크(torsion torque)를 받으면서 고속 회전함에 따라 진동 및 소음이 발생되면 센터 베어링(3)에 고정된 베어링 브라켓(4)을 통해 발생된 진동 및 소음이 차체(5)측으로 전달된다.First, when vibration and noise are generated as the propulsion shaft 1 rotates at high speed while driving the engine, the vibration and noise generated through the bearing bracket 4 fixed to the center bearing 3 are generated. It is transmitted to the vehicle body 5 side.
상기한 바와 같이 전달되는 진동 및 소음은 센터 베어링(3)에 고정된 베어링 브라켓(4)을 통해 메인 브라켓(9)측으로 전달될려고 하지만, 상기 베어링 브라켓(4)과 메인 브라켓(9)사이에는 진동 및 소음을 흡수하는 제 1 방진루버(10)가 보울트(11)에 끼워지게 설치되어 있으므로 상기 제 1 방진고무가 진동 및 소음을 1차적으로 흡수하여 감쇄시키게 된다.The vibration and noise transmitted as described above are intended to be transmitted to the main bracket 9 side through the bearing bracket 4 fixed to the center bearing 3, but there is no vibration between the bearing bracket 4 and the main bracket 9. And since the first dustproof louver 10 for absorbing noise is installed to be fitted to the bolt 11, the first dustproof rubber primarily absorbs and attenuates vibration and noise.
이와 같이 추진축(1)의 구동에 따라 발생된 진동 및 소음이 베어링브라켓(4)을 통해 메인 브라켓(9)측으로 전달되면서 제 1 방진루버(10)에 의해 1차적으로 감쇄된 상태에서 메인 브라켓(9)을 통해 차체(5)측으로 전달되면 상기 메인 브라켓(9)과 차체(5)를 지지하는 보울트(14)에는 진동 및 소음을 2차적으로 흡수하는 제 2 방진고무(13)가 끼워져 있어 상기 제 2 방진고무가 진동 및 소음을 2차적으로 감쇄시키게 되므로 차체로 전달되는 진동 및 소음이 최소화되는 것이다.As such, the vibration and noise generated by the driving of the propulsion shaft 1 are transmitted to the main bracket 9 through the bearing bracket 4, and the main bracket (1) is first attenuated by the first dustproof louver 10. 9) the second anti-vibration rubber 13, which absorbs vibration and noise secondary, is fitted in the bolt 14 supporting the main bracket 9 and the vehicle body 5 when the vehicle body 5 is transmitted to the vehicle body 5 side. Since the second anti-vibration rubber attenuates vibration and noise secondarily, vibration and noise transmitted to the vehicle body are minimized.
이상에서와 같이 본 발명은 베어링 브라켓(4)과 차체(5)사이에 별도의 메인 브라켓(9)을 설치하고 이들의 연결부위에는 각각 방진고무(10)(13)를 설치하므로 인해 추진축(1)의 구동시 발생되는 진동 및 소음이 차체(5)로 전달되는 현상을 최소화하게 되고, 이에 따라 NVH 성능을 향상시킬 수 있게 되는 효과를 얻게 된다.As described above, according to the present invention, a separate main bracket 9 is installed between the bearing bracket 4 and the vehicle body 5, and the anti-vibration rubbers 10 and 13 are respectively installed at the connection portions thereof. Minimization of vibration and noise generated during driving of the vehicle to the vehicle body 5 is achieved, thereby obtaining an effect of improving NVH performance.
