Relates to a flanged yoke joint.

일반적으로 전기관 후륜 구동방식의 자동차는 변속기의 출력을 종감속 장치에 전달하는 추진축이 장착되어 있다.In general, an electric tube rear wheel drive vehicle is equipped with a propulsion shaft for transmitting the output of a transmission to a longitudinal reduction gear.

도 1에 도시되는 바와 같이, 추진축(106)은 요철이 심한 노면을 주행할 때, 차륜의 진동으로 변속기 출력축(101)과 종감속 차동장치(108)의 입력축(107)이 이루는 각도의 변화에 수시로 대응하도록 하는 십자형 자재이음(120)이 설치되어 있으며, 그 추진축(106)은 십자형 자재이음(106)을 사이에 두고 출력축(101), 입력축(107)에 플렌지 요크 조인트(110)로 연결되어 있다.As shown in FIG. 1, when the driving shaft 106 travels on a rough road surface, the propulsion shaft 106 is subjected to a change in the angle between the transmission output shaft 101 and the input shaft 107 of the longitudinal reduction differential device 108 due to the vibration of the wheel. The cross-shaped material joint 120 is installed so as to respond from time to time, the propulsion shaft 106 is connected to the output shaft 101, the input shaft 107 by the flange yoke joint 110 with the cross-shaped material joint 106 in between. have.

그럼, 여기서 종래 추진축 플렌지 요크 조인트의 한 예를 도 2 및 도 3에 도시하였는바, 이를 간단히 살펴보면 다음과 같다.Then, an example of a conventional propulsion shaft flange yoke joint is shown in FIGS. 2 and 3, which will be briefly described as follows.

도시되는 바와 같이, 플렌지 요크 조인트(110)는 2개의 플렌지 요크(111)(112)의 접촉면에 서로 대향하는 요철부(115)(116)를 갖는 세레이션(117)이 형성되고, 각 플렌지 요크(111)(112)의 접촉면에 4개의 체결공(114)이 관통 형성되어 있어, 각 플렌지 요크(111)(112)의 세레이션(117)을 서로 접촉시키고 체결공(114)에 볼트(118)를 삽입한 후, 그 볼트(118)에 너트(119)를 체결하여 서로 조인트시켰다.As shown, the flange yoke joint 110 is formed with a serration 117 having concave-convex portions 115 and 116 facing each other on the contact surfaces of the two flange yokes 111 and 112, and each flange yoke Four fastening holes 114 are formed through the contact surfaces of the 111 and 112 so that the serrations 117 of the flange yokes 111 and 112 are brought into contact with each other and the bolts 118 are fastened to the fastening holes 114. ) Was inserted, and then the nuts 119 were fastened to the bolts 118 and jointed with each other.

이러한 플렌지 요크 조인트(110)는 일측의 플렌지 요크(111)로부터 전달되는 회전토크를 접촉면의 세레이션(117) 및 체결공(114)에 체결된 볼트(118)를 통해 타측의 플렌지 요크(112)로 전달하게 된다.The flange yoke joint 110 is the flange yoke 112 of the other side through the bolt 118 fastened to the serration 117 and the fastening hole 114 of the rotational torque transmitted from the flange yoke 111 on one side. Will be sent to.

그러나, 기어변속이나 1단 출발시 변속기로부터 급격하게 플렌지 요크 조인트(110)를 통해 추진축에 전달되는 회전토크는 상대적으로 추진축에 비틀림 응력을 집중시켜, 내구성을 저하시켰다.However, the rotational torque transmitted to the propulsion shaft through the flange yoke joint 110 from the transmission at the time of gear shifting or first stage relatively concentrated torsional stress on the propulsion shaft, thereby reducing durability.

또한, 추진축에서 발생되는 진동은 플렌지 요크 조인트(110)를 통해 그대로 변 속기나 종감속 차동장치에 전달되어 차체의 내구성 역시 저하시켰다.In addition, the vibration generated from the propulsion shaft is transmitted to the transmission or the longitudinal reduction differential as it is through the flange yoke joint 110, thereby lowering the durability of the vehicle body.

따라서, 본 고안은 상기와 같은 종래의 문제점을 감안하여 안출된 것으로서, 변속기로부터 추진축에 급격하게 전달되는 회전토크 및 추진축으로부터 변속기 및 종감속 차동장치로 전달되는 진동을 흡수함으로서, 급격한 회전토크에 따른 추진축의 내구성 취약 및 진동전달에 따른 차체의 내구성 취약을 극복할 수 있도록 하는 충격흡수를 위한 추진축 플렌지 요크 조인트를 제공하는데 그 목적이 있다.Therefore, the present invention has been devised in view of the conventional problems as described above, by absorbing the rotational torque rapidly transmitted from the transmission to the propulsion shaft and the vibration transmitted from the propulsion shaft to the transmission and the longitudinal reduction differential device, according to the rapid rotational torque It is an object of the present invention to provide a propulsion shaft flange yoke joint for shock absorption that can overcome the durability weakness of the propulsion shaft and the durability weakness of the vehicle body due to vibration transmission.

이하, 본 고안의 실시예를 첨부도면에 의거 더욱 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in more detail based on the accompanying drawings.

본 고안의 실시예에 따른 충격흡수를 위한 자동차 추진축 플렌지 요크 조인트(10)는 도 4 및 5에 도시되는 바와 같이, 2개의 플렌지 요크(11)(12)의 접촉면에 서로 대향하는 요부(16)와 철부(15)를 갖는 세레이션(17)이 형성되되, 요부(16)는 철부(15)보다 넓게 형성되어 요부(16)가 철부(15)의 사이에 탄성부재(20)가 삽입된다. 그 탄성부재(20)는 고무 등에 의해 이루어진다.The automobile propulsion shaft flange yoke joint 10 for shock absorption according to an embodiment of the present invention, as shown in Figs. 4 and 5, the main portion 16 facing each other on the contact surface of the two flange yoke (11) (12) And a serration 17 having a convex portion 15 is formed, and the concave portion 16 is formed wider than the convex portion 15 so that the concave portion 16 is inserted between the convex portions 15. The elastic member 20 is made of rubber or the like.

한 편, 상기 각 플렌지 요크(11)(12)의 접촉면에 원주상을 따라 장방향으로 4개의 체결공(14)이 관통 형성되어 체결공(14)에 볼트(18)를 삽입한 후, 그 볼트(18)에 너트(19)를 체결하여 각 플렌지 요크(11)(12)를 서로 조인트한다.On the other hand, four fastening holes 14 are formed through the contact surfaces of the flange yokes 11 and 12 in the longitudinal direction along the circumferential direction to insert the bolts 18 into the fastening holes 14. The nut 19 is fastened to the bolt 18 to joint the flange yokes 11 and 12 with each other.

이와 같이 구성되는 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the subject innovation is configured as follows.

변속기의 출력축으로부터의 일측 플렌지 요크(11)에 전달되는 회전토크는 세레이션(17)을 통해 타측 플렌지 요크(12)에 직접 전달되지 않고, 일측의 세레이션(17)을 통해 탄성부재(20)에 전달되어 일단 탄성부재(20)를 압축시키면서 타측의 세레이션(17), 타측의 플렌지 요크(11)(12)를 통해 추진축으로 전달된다. 상기 탄성부재(20)가 압축될 때, 볼트(18)가 결합된 체결공(14)은 서로 슬립변위를 이룬다. 즉, 체결공(14)은 장방형으로 이루어져 플렌지 요크(11)에 일단 회전 토크가 전달되면 타측 플렌지 요크(12)는 정지상태이므로 탄성부재(20)가 압축되는 동안 볼트(18)만이 체결공(14)을 따라 회전한다.The rotational torque transmitted to the one flange yoke 11 from the output shaft of the transmission is not directly transmitted to the other flange yoke 12 through the serration 17, but the elastic member 20 through the serration 17 on one side. Is transmitted to the propulsion shaft through the serration 17 of the other side, the flange yoke 11, 12 of the other side while compressing the elastic member 20 once. When the elastic member 20 is compressed, the fastening holes 14 to which the bolts 18 are coupled make slip displacement with each other. That is, the fastening hole 14 has a rectangular shape and once the rotational torque is transmitted to the flange yoke 11, the other flange yoke 12 is in a stopped state, so only the bolt 18 is fastened while the elastic member 20 is compressed. Rotate along 14).

이에따라, 기어변속이나 1단 출발시 변속기로부터 급격하게 플렌지 요크 조인트(10)을 통해 추진축에 전달되는 회전토크는 탄성부재(20)에서 일단 흡수되면서 전달되게 됨으로서, 급격한 회전토크의 전달에 따른 순간적으로 작용하는 추진축의 비틀림응력집중을 방지할 수 있다.Accordingly, the rotational torque transmitted to the propulsion shaft through the flange yoke joint 10 from the transmission at the time of gear shifting or first stage is absorbed by the elastic member 20 and then transmitted, thereby providing instantaneous rotational torque. It is possible to prevent torsional stress concentration on the acting propulsion shaft.

또한, 추진축에서 발생되는 진동 역시, 플렌지 요크 조인트(10)내에 설치된 탄성부재(20)에서 흡수되면서 변속기나 종감속 차동장치에 전달되므로 차체의 내구성 취약을 방지할 수 있다.In addition, the vibration generated from the propulsion shaft is also absorbed by the elastic member 20 installed in the flange yoke joint 10 to be transmitted to the transmission or the longitudinal reduction differential device, thereby preventing the durability of the vehicle body.

이상에서 살펴본 바와 같이, 본 고안은 변속기로부터 추진축에 급격하게 전달되는 회전토크 및 추진축으로부터 변속기 및 종감속 차동장치로 전달되는 진동을 흡수함으로서, 급격한 회전토크에 따른 추진축의 내구성 취약 및 진동전달에 따른 차체의 내구성 취약을 극복하여 내구성을 증대시킬 수 있는 매우 유용한 것이다.As described above, the present invention absorbs the rotational torque rapidly transmitted from the transmission to the propulsion shaft and the vibration transmitted from the propulsion shaft to the transmission and the longitudinal reduction differential device, resulting in the weak durability of the propulsion shaft due to the sudden rotational torque and the vibration transmission. It is very useful to overcome the weakness of the durability of the vehicle body and increase the durability.

본 고안은 특정의 실시예와 관련하여 도시 및 설명하였지만, 첨부 실용 신안등록청구범위에 의해 나타난 본 고안의 사상 및 영역으로부터 벗어나지 않는 한도내에서 다양한 개조 및 변화가 가능하다는 것을 당업계에서 통상의 지식을 가진 자라면 누구나 쉽게 알 수 있을 것이다.Although the present invention has been shown and described in connection with specific embodiments, it is common knowledge in the art that various modifications and changes can be made without departing from the spirit and scope of the present invention as indicated by the appended utility model registration claims. Anyone who has a can easily know.
