Description

추진축용 센터베어링 지지장치Center Bearing Support Device for Propulsion Shaft

본 발명은 추진축용 센터베어링 지지장치에 관한 것으로, 더 상세하게는 그 작업공수를 절감하고 진동 흡수효과를 향상시킴과 아울러, 볼트의 느슨함 발생을 방지하여 드라이브라인의 일직선 유지가 가능하도록 발명된 것이다.The present invention relates to a center bearing support device for the propulsion shaft, and more particularly, to reduce the workmanship and improve the vibration absorption effect, and to prevent the loosening of bolts to maintain the straight line of the driveline will be.

일반적으로 엔진의 동력은 변속기(4)를 거쳐서 추진축(10)에 의해 차동기어(9)를 거쳐 구동방퀴로 전달되는데, 대부분의 경우 변속기(4)는 엔진, 클러치와 함께 프레임에 장치되어 있으며 구동바퀴는 섀시 스프링을 통하여 차체에 장치되어 있으므로 노면으로부터의 충격이나 적하의 변화 등에 따라 상하로 움직인다.In general, the power of the engine is transmitted to the drive wheel via the transmission shaft (10) by the propulsion shaft (10) through the transmission (4). In most cases, the transmission (4) is installed in the frame together with the engine and the clutch. Since the driving wheel is mounted on the vehicle body through the chassis spring, the drive wheel moves up and down according to the impact from the road surface or the change of dripping.

그 때문에 엔진의 동력을 지장없이 구동바퀴에 전달하기 위해서 추진축(10)의 양끝에 유니버설 조인트(8)가 장치되어 있다.Therefore, the universal joint 8 is attached to both ends of the propulsion shaft 10 in order to transmit the engine power to the driving wheel without any trouble.

또한, 추진축(10)은 끊임없이 변동하는 엔진의 토크를 받으면서 고속회전을 하므로 비틀림 진동을 일으키기 쉽고, 또 축이 구부러지거나 기하학적 중심과 질량적 중심이 일치하지 않을 때는 휠링(whirling)이라는 굽힘 진동을 일으킬 염려가 있다.In addition, since the propulsion shaft 10 rotates at a high speed while receiving a constantly varying torque of the engine, it is easy to cause torsional vibration, and when the shaft is bent or when the geometric center and the mass center do not coincide with each other, the propulsion shaft 10 causes a bending vibration called wheeling. There is concern.

이들의 진동과 추진축(10)의 고유진동수와의 공명이 일어나면 파괴현상이 일어나므로 상용 회전속도에서는 공명진동(공진)이 일어나지 않도록 해야 하며, 그 진동이 차체로 전달되는 것을 감쇄하기 위한 감쇄용 러버부시(5)가 매개체로 설치된다.Resonance occurs when these vibrations resonate with the natural frequency of the propulsion shaft 10. Therefore, resonance vibration (resonance) should not occur at a commercial rotational speed, and a damping rubber for attenuating transmission of the vibration to the vehicle body. The bush 5 is installed as a medium.

추진축(10)은 중심에 비해 비틀림이나 굽힘에 강한 중공(中空)의 탄소강관이 일반적으로 사용되고 있으며, 축의 단면적이 정해져 있을 때는 길이가 길어지면 갑자기 위험 회전속도가 작아지는 경향이 있으므로 2개로 분할하기도 한다.The propulsion shaft 10 is generally a hollow carbon steel pipe that is stronger in torsion or bending than the center, and when the cross section of the shaft is determined, the propulsion shaft 10 tends to suddenly decrease in dangerous rotational speed as the length of the shaft is divided into two. do.

한편, 추진축(10)이 장축을 이룰 때는 이를 지지하기 위해 센터베어링(20)이 필수적으로 설치된다.On the other hand, when the propulsion shaft 10 achieves a long axis, the center bearing 20 is essentially installed to support it.

이 센터베어링(20)은 차체(1)에 결합되는 데, 추진축(10)의 회전진동이 차체(1)에 전달되는 것을 방지하기 위해 도 2에서와 같이 좌우에 러버부시(40)가 각각 매개체로 설치되는 것이다.The center bearing 20 is coupled to the vehicle body 1, in order to prevent the rotational vibration of the propulsion shaft 10 from being transmitted to the vehicle body 1, as shown in FIG. To be installed.

종래, 러버부시(40)는 링형상의 고무재로 성형되어 센터베어링(20)을 지지하는 브라켓트(30)와 차체(1) 사이에 위치되어 고정용 볼트(2)가 관통하여 차체(1)에 체결되는 것에 의해 설치가 이루어 지도록 구성된다.Conventionally, the rubber bush 40 is formed between the bracket 30 supporting the center bearing 20 and the vehicle body 1 by being molded of a ring-shaped rubber material so that the fixing bolt 2 penetrates the vehicle body 1. It is configured to be made by being fastened to.

이와같이 종래 고무재로 된 러버부시(40)는 내마모성 및 부식에 약하다.Thus, the rubber bush 40 made of a conventional rubber material is weak to wear resistance and corrosion.

따라서, 러버부시(5)가 마모될 경우 볼트(2)가 헐거워 지거나 변속기(4)와 차동기어(9)의 사이를 연결하는 추진축(10)이 일직선을 유지하지 못하도록 변형되어 차량 진동발생의 원인이 되었던 것이다.Therefore, when the rubber bush 5 is worn, the bolt 2 may be loosened or the propulsion shaft 10 connecting the transmission 4 and the differential gear 9 may be deformed so as not to maintain a straight line, thereby causing vehicle vibration. It would have been.

또한, 추진축(10)의 조립시에 와셔(6)와 러버부시(5)를 공체해야 하므로 작업성이 저하되는 등의 폐단이 있었던 것이다.In addition, since the washer 6 and the rubber bush 5 must be replaced when the propulsion shaft 10 is assembled, there is a closed end such as deterioration of workability.

본 발명의 목적은 보다 댐핑효과가 우수하도록 된 추진축용 센터베어링 지지장치를 제공하는 데 있다.An object of the present invention to provide a center bearing support device for the propulsion shaft to be more excellent damping effect.

본 발명의 다른 목적은 장시간 주행 후에도 드라이브 라인이 일직선을 유지하여 내구성이 향상되도록 한 추진축용 센터베어링 지지장치를 제공하는 데 있다.It is another object of the present invention to provide a center bearing support device for a propulsion shaft which maintains a straight line even after a long run to improve durability.

본 발명의 또 다른 목적은 볼트의 느슨함 발생을 방지하여 제품의 신뢰성이 향상되도록 한 추진축용 센터베어링 지지장치를 제공하는 데 있다.Another object of the present invention to provide a center bearing support device for the propulsion shaft to prevent the loosening of the bolt to improve the reliability of the product.

이러한 본 발명의 목적은, 추진축(10)을 차체(1)에 센터베어링(20)으로 지지하고, 이 센터베어링(20)을 차체(1)에 고정하는 브라켓트(30)와 차체(1)의 사이에 진동을 감쇄하기 위한 감쇄부재(40)가 볼트(2)로 체결 고정되는 것에 있어서;The object of the present invention is to support the propulsion shaft 10 to the vehicle body 1 by the center bearing 20 and to fix the center bearing 20 to the vehicle body 1 of the bracket 30 and the vehicle body 1. In the attenuating member 40 for attenuating the vibration between the fastening and fixed with the bolt (2);

상기 감쇄부재(40)는 차체(1)와 브라켓트(30)에 각각 접하는 가이드(42)(43)의 사이로 코일스프링(42)을 탄력 설치하는 것에 의해 달성된다.The damping member 40 is achieved by elastically installing the coil spring 42 between the guides 42 and 43, which are in contact with the vehicle body 1 and the bracket 30, respectively.

따라서, 코일스프링(42)이 상하 댐핑역할과 아울러, 압축상태를 유지하여 장시간 주행 후에도 최초 셋팅한 상태를 유지하므로 드라이브라인이 일직선을 항상 유지하게 된다.Therefore, the coil spring 42 maintains a straight line because the coil spring 42 plays a vertical damping role and maintains a compressed state to maintain the initial setting even after a long run.

또, 초기의 품질을 유지함과 아울러 조립성이 개선되는 것이다.In addition, the assembly quality is improved while maintaining the initial quality.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의해 상세하 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 3는 본 발명의 감쇄부재(40) 구조를 보인 조립단면도로 브라켓트(30)와 차체(1) 사이에 코일스프링(42)이 탄력 설치되는 구조를 보이고 있다.3 is a cross-sectional view showing the structure of the damping member 40 of the present invention shows a structure in which the coil spring 42 is elastically installed between the bracket 30 and the vehicle body 1.

이 감쇄부재(40) 주로 중간이 분할되는 분할식의 추진축(10)을 센터베어링(20)으로 지지할 때 추진축(10)의 회전진동을 차체(1)에 전달되는 것을 감쇄하기 위해 설치된다.The damping member 40 is provided to attenuate the transmission of the rotational vibration of the propulsion shaft 10 to the vehicle body 1 when supporting the divided propulsion shaft 10 mainly divided by the center bearing 20.

즉, 센터베어링(20)을 차체(1)에 고정하는 브라켓트(30)와 차체(1)의 사이에 코일스프링(42)을 위치한 상태에서 볼트(2)로 관통되어 너트(3)로 체결 고정되는 것에 의해, 센터베어링(20)과 차체(1)의 사이에는 이 코일스프링(42)이 매개체로 위치되는 결과로 진동의 전달을 감쇄하게 되는 것이다.That is, in the state where the coil spring 42 is positioned between the bracket 30 that fixes the center bearing 20 to the vehicle body 1 and the vehicle body 1, the bolts 2 are penetrated and fastened to the nut 3. As a result, the coil spring 42 is attenuated between the center bearing 20 and the vehicle body 1 to attenuate the transmission of vibration.

이때, 코일스프링(42)의 양단에는 차체(1)에 접하는 위치, 그리고 브라켓트(30)에 접하는 위치로 코일스프링(42)의 이탈 및 유동을 방지하기 위한 가이드(42)(43)가 위치된 상태에서 볼트(2)와 너트(3)로 체결하여 센터베어링(20)의 설치가 이루어 지는 것이다.At this time, both ends of the coil spring 42 are positioned in contact with the vehicle body 1, and guides 42 and 43 for preventing separation and flow of the coil spring 42 are positioned in contact with the bracket 30. The bolt (2) and the nut (3) in the state is the installation of the center bearing 20 is made.

이와같은 본 발명의 구성에 의하면, 코일스프링(42)이 상,하 댐핑역할을 수행하게 된다.According to the configuration of the present invention as described above, the coil spring 42 performs the upper and lower damping role.

이때, 볼트(2)로 센터베어링(20) 고정용 브라켓트(30)를 차체(1)에 결합할 때 코일스프링(42)은 압축상태를 받게 되므로 장시간 주행 후에도 최초 셋팅한 값이 그대로 유지된다.In this case, when the center bearing 20 fixing bracket 30 is coupled to the vehicle body 1 with the bolts 2, the coil spring 42 receives a compressed state, and thus the first set value is maintained even after a long driving.

따라서, 변속기(4)와 차동기어(9)를 연결하는 추진축(10)의 드라이브 라인이 최초 조립할 때와 같이 항상 일직선으로 유지되어 초기의 최적상태를 지속적으로 유지하게 된다.Therefore, the drive line of the propulsion shaft 10 connecting the transmission 4 and the differential gear 9 is always kept in a straight line as in the initial assembly, so that the initial optimum state is continuously maintained.

상기와 같은 본 발명은, 코일스프링(42)이 상하 댐핑역할과 아울러, 압축상태를 유지하여 항상 최초 셋팅한 상태를 유지하므로 드라이브라인이 일직선을 항상 유지하게 된다.In the present invention as described above, as the coil spring 42 serves to damp up and down, and maintains a compressed state, the drive line is always maintained in a straight line.

따라서, 초기의 품질을 유지하게 된다.Thus, the initial quality is maintained.

또, 조립 부품수와 공수가 절감되어 조립성이 개선되는 등의 매우 유용한 발명인 것이다.In addition, it is a very useful invention that the number of assembly parts and man-hours is reduced to improve the assembly.
