Description
본 고안은 자동차 등속조인트용 댐퍼에 관한 것으로서, 더욱 상세하게는 자동차 등속조인트의 샤프트와 축결합하는 댐퍼의 내주면에 이탈방지돌기를 형성하여댐퍼와 샤프트 사이의 압착력을 높여줌으로써 댐퍼의 위치변경으로 인해 발생하는 성능 저하를 줄여주는 자동차 등속조인트용 댐퍼에 관한 것이다.The present invention relates to a damper for a constant velocity joint of an automobile, and more particularly, by forming an escape prevention protrusion on the inner circumferential surface of the damper that is axially coupled to the shaft of the constant velocity joint of the automobile, thereby increasing the compressive force between the damper and the shaft, thereby changing the position of the damper. The present invention relates to a damper for an automobile constant velocity joint that reduces the performance degradation that occurs.
일반적으로 드라이브 샤프트는 종감속장치에서 바퀴측에 구동력을 전달하는 회전축으로서, 드라이브 샤프트의 교차각이 커지더라도 바퀴측에 동력을 등속으로 전달하는 등속조인트가 설치되고, 차종에 따라서는 등속조인트가 공진할 때 등속조인트 대신에 진동하여 등속조인트에 발생하는 진동, 소음을 감소시키는 댐퍼가 설치된다.In general, the drive shaft is a rotary shaft that transmits driving force to the wheel side in the longitudinal reduction gear. Even if the crossing angle of the drive shaft increases, a constant velocity joint is installed on the wheel side to transmit power at constant speed, and the constant velocity joint resonates depending on the vehicle type. Instead of constant velocity joints, dampers are installed to reduce vibrations and noise generated at the constant velocity joints.
도 1은 종래의 자동차 등속조인트용 댐퍼가 장착된 드라이브 샤프트의 단면도이다.1 is a cross-sectional view of a drive shaft equipped with a damper for a conventional automotive constant velocity joint.
댐퍼는 도 1에 도시된 바와 같이, 드라이브 샤프트(102)의 외주면에 끼워지고, 일측이 밴드(104)로 드라이브 샤프트(102)에 고정되는 탄성부재(106)와, 이 탄성부재(106)의 외주연에 둘레방향으로 결합된 질량체(108)로 이루어진다.As shown in FIG. 1, the damper is fitted to an outer circumferential surface of the drive shaft 102, and one side of the elastic member 106 is fixed to the drive shaft 102 by a band 104. It consists of a mass body 108 coupled to the outer periphery in the circumferential direction.
이러한 댐퍼는 등속조인트에서 발생되는 진동이 탄성부재(106)를 통하여 질량체(108)로 전달되면 질량체(108)가 등속조인트의 고유진동을 흡수하여 진동하므로 등속 조인트의 진동 및 소음을 감소시킨다.Such dampers reduce the vibration and noise of the constant velocity joint when the vibration generated in the constant velocity joint is transmitted to the mass body 108 through the elastic member 106 and absorbs the natural vibration of the constant velocity joint.
그러나 상기한 바와 같은 드라이브 샤프트의 댐퍼는 샤프트와 축결합하는 내주면이 고무재질로 되어있어 밀착력은 좋으나 평평한 구조로 인하여 외부 충격이나 마모로 인해 댐퍼의 위치 이동이 심하게 나타나 진동 저감기능을 유지할 수 없다는 문제점이 있다.However, the damper of the drive shaft as described above has a good adhesion because the inner circumferential surface of the drive shaft is axially coupled to the shaft, but due to the flat structure, the damper is severely moved due to external impact or abrasion, and thus the vibration reduction function cannot be maintained. There is this.
본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 발명의 목적은 자동차 등속조인트의 샤프트와 축결합하는 댐퍼의 내주면에 이탈방지돌기를 형성하여 댐퍼와 샤프트 사이의 압착력을 높여줌으로써 댐퍼의 위치변경이 쉽게되지 않아 진동 저감기능을 유지할 수 있게 해주는 자동차 등속조인트용 댐퍼를 제공하는데 있다.The present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to form a separation preventing projection on the inner peripheral surface of the damper axially coupled with the shaft of the automobile constant velocity joint to increase the pressure between the damper and the shaft position of the damper It is to provide a damper for automobile constant velocity joints that can be easily changed to maintain vibration reduction function.

탄성부재는 내주면에 상기 샤프트에서 이탈되는 것을 방지하기 위한 수개의 돌기가 형성된 것을 특징으로 한다.The elastic member is characterized in that a plurality of protrusions formed on the inner peripheral surface for preventing the departure from the shaft.
이하, 본 고안에 따른 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명한다. 도 2a는 본 고안의 일실시예에 따른 자동차 등속조인트용 댐퍼의 단면도이다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in detail. 2A is a cross-sectional view of a damper for an automobile constant velocity joint according to an embodiment of the present invention.
본 고안에 따른 댐퍼(200)는 도 2에 도시된 바와 같이, 드라이브 샤프트(202)의 외주면에 끼워지고, 일측이 밴드(204)로 드라이브 샤프트(202)에 고정되는 탄성부재(206)와, 이 탄성부재(206)의 외주연에 둘레방향으로 결합된 질량체(208)로 이루어진다.Damper 200 according to the present invention, as shown in Figure 2, the elastic member 206 is fitted to the outer peripheral surface of the drive shaft 202, one side is fixed to the drive shaft 202 by a band 204, It consists of a mass body 208 coupled to the outer periphery of the elastic member 206 in the circumferential direction.
상기 탄성부재(208)는 내주면에는 탄성부재가 상기 드라이브 샤프트(202)에서 이탈을 방지하기 위한 수개의 이탈방지돌기(이하 돌기)(209)가 형성되어 있다. 또한 돌기(209)는 톱니모양으로 샤프트(202)가 축결합되는 방향쪽에는 소정각도 기울어진 톱니면이 형성되고 반대방향 쪽에는 거의 수직인 톱니면이 형성되어 있다. 또한 상기 탄성부재(208)의 내주면이 이루는 둘레의 직경은 샤프트(202)의 직경과 동일하고 탄성부재(208)의 내주면에 형성된 돌기(209)는 2mm정도의 높이를 가진다.The elastic member 208 is formed on the inner circumferential surface of the plurality of separation preventing projections (hereinafter referred to as projections) 209 for preventing the elastic member from being separated from the drive shaft 202. In addition, the projection 209 is formed in a sawtooth surface inclined at a predetermined angle on the side in which the shaft 202 is axially coupled in a sawtooth shape, and a substantially vertical tooth surface on the opposite side. In addition, the diameter of the circumference formed by the inner circumferential surface of the elastic member 208 is the same as the diameter of the shaft 202 and the protrusion 209 formed on the inner circumferential surface of the elastic member 208 has a height of about 2 mm.
상기한 구성에 의한, 본 고안의 일실시예에 따른 자동차 등속조인트용 댐퍼(200)의 작용은 다음과 같다. 도 2b는 본 고안의 일실시예에 따른 자동차 등속조인트용 댐퍼가 드라이브 샤프트에 결합된 단면도이다.By the above-described configuration, the action of the damper 200 for automobile constant velocity joint according to an embodiment of the present invention is as follows. Figure 2b is a cross-sectional view of the damper for the constant velocity joint of the vehicle coupled to the drive shaft according to an embodiment of the present invention.
도 2b를 참조하면, 먼저 탄성부재(206)에 이탈방지돌기(209)가 형성된 댐퍼가(200)에 드라이브 샤프트(202)가 축결합된다. 이때 샤프트(202)의 외주면은 탄성부재(206)의 돌기(209)의 소정각도 기울어진 면과 접하게 되고 돌기(209)는 샤프트(202)의 외주면에 의해 눌려 삽입되는 반대방향, 즉 돌기가 수직한 면쪽으로 눕게 된다. 이때 돌기(209)가 삽입되는 반대방향으로 눕기때문에 샤프트(202)의 결합이 용이하게 된다. 또한 샤프트가 삽입된 방향의 반대쪽으로 이탈시에는 돌기(209)의 기울어진 면이 샤프트(202)의 면에 걸리기 때문에 삽입된 반대방향으로 쉽게 빠지않게 해준다. 또한 상기 탄성부재(206)의 직경은 샤프트(202)의 직경과 같고 탄성부재(206)의 형성된 돌기가 2mm정도의 높이를 가지기때문에 결합후의 압찰력이 높아진다.Referring to FIG. 2B, first, the drive shaft 202 is axially coupled to the damper 200 having the separation preventing protrusion 209 formed on the elastic member 206. At this time, the outer peripheral surface of the shaft 202 is in contact with the inclined surface of the predetermined angle of the projection 209 of the elastic member 206 and the projection 209 is pressed in the opposite direction that is inserted by the outer peripheral surface of the shaft 202, that is, the projection is vertical Lie down on one side. At this time, since the projection 209 is laid in the opposite direction to be inserted, the coupling of the shaft 202 is facilitated. Also, when the shaft deviates from the opposite direction of insertion, the inclined surface of the protrusion 209 is caught on the surface of the shaft 202 so that the shaft does not easily fall in the opposite direction of insertion. In addition, since the diameter of the elastic member 206 is the same as the diameter of the shaft 202 and the formed projection of the elastic member 206 has a height of about 2mm, the pressure force after the coupling is increased.
따라서, 샤프트(202)에 결합되는 댐퍼(200)가 이탈방지돌기(209)에 의해 높은 압찰력을 가진채로 처음 설치한 위치에 고정될 수 있어 진동 저감효과를 계속 유지할 수 있게 해준다.Therefore, the damper 200 coupled to the shaft 202 can be fixed to the position of the first installation with a high pressure force by the departure prevention protrusion 209 to maintain the vibration reduction effect.
상술한 바와 같이 하여 본 고안에 의한 자동차 등속조인트용 댐퍼는 자동차 등속조인트의 샤프트와 축결합하는 댐퍼의 내주면에 이탈방지돌기를 형성하여 댐퍼와 샤프트 사이의 압착력을 높여줌으로써 댐퍼의 위치변경이 쉽게되지 않아 진동 저감기능을 유지할 수 있게 해주는 효과가 있다.As described above, the damper for automobile constant velocity joint according to the present invention forms an escape prevention protrusion on the inner circumferential surface of the damper that is axially coupled with the shaft of the automobile constant velocity joint to increase the compressive force between the damper and the shaft, thereby making it easier to change the position of the damper. It does not have the effect of maintaining the vibration reduction function.
