일반적으로, 후륜 구동 차량에는 변속기의 토크를 종감속장치로 전달하는 프로펠러샤프트가 차체의 길이방향으로 설치된다.In general, a propeller shaft for transmitting the torque of the transmission to the longitudinal reduction gear is provided in the longitudinal direction of the vehicle body in the rear wheel drive vehicle.
상기의 프로펠러샤프트에는 차량의 종류 및 동력전달장치의 구성에 따라 도 1에 도시된 바와 같이 다수의 유니버설 조인트(1) 및 플랜지 요크(2)가 사용되며, 또한 전장이 축의 길이방향으로 가변되는 슬립조인트(3)도 함께 적용된다.In the propeller shaft, a plurality of universal joints 1 and a flange yoke 2 are used as shown in FIG. 1 according to the type of vehicle and the configuration of the power transmission device, and the slip of which the overall length is varied in the longitudinal direction of the shaft. The joint 3 is also applied together.
여기서, 상기 유니버설 조인트(1)와 플랜지 요크(2)는 일명 십자축이라고 불리우는 스파이더(4;spider)에 의해 서로의 결합이 이루어지게 된다.Here, the universal joint 1 and the flange yoke 2 are coupled to each other by a spider 4 called a cross axis.
즉, 상기 스파이더(4)의 각 단부(네개의 축)에는 니들롤러베어링(41)이 끼워져서 결합되고, 상기 니들롤러베어링(41)은 베어링캡(42)에 의해 감싸여져 보호되게 되며, 상기 베어링캡(42)의 하단은 실(43)에 의해 밀봉되는 구조로 되어 있다.That is, the needle roller bearings 41 are fitted to each end (four shafts) of the spider 4, and the needle roller bearings 41 are wrapped and protected by the bearing caps 42. The lower end of the bearing cap 42 is sealed by the seal 43.
따라서, 니들롤러베어링(41)과 베어링캡(42)이 결합된 스파이더(4)의 각 단부 중 두개의 축은 도시된 바와 같이 유니버설 조인트(1)의 결합구멍(1a)으로 끼워지고 나머지 두 개의 축은 플랜지 요크(2)의 결합구멍(도시않됨)으로 끼워지게 되며, 이와 같이 유니버설 조인트(1)의 결합구멍(1a)과 플랜지 요크(2)의 결합구멍으로 끼워진 스파이더(4)의 축은 각각 스냅링(44)에 의해 고정되어지게 된다.Accordingly, two axes of each end of the spider 4 to which the needle roller bearing 41 and the bearing cap 42 are coupled are fitted into the coupling holes 1a of the universal joint 1 as shown, and the other two axes are The shaft of the spider 4 fitted into the coupling hole (not shown) of the flange yoke 2 and the coupling hole 1a of the universal joint 1 and the coupling hole of the flange yoke 2 are each snap ring ( 44) to be fixed.

In bar, such a vertical flow of the needle roller bearing 41 eventually develops into a phenomenon in which the needle roller bearing 41 is sintered by frictional heat, and thus the durability of the spider 4 is reduced. .
이에 본 발명은 상기한 같은 문제점을 해소하기 위해 안출된 것으로, 니들롤러베어링의 상단과 하단을 스러스트와셔 및 서포트링을 통해 지지토록 하여 상하방향으로의 유동을 차단함으로써, 니들롤러베어링의 소착현상을 예방하고 이에 따라 스파이더의 내구성을 증대시킬 수 있도록 하는 자동차의 프로펠러샤프트 구조를 제공함에 그 목적이 있다. Accordingly, the present invention has been made to solve the above problems, by blocking the flow in the vertical direction by supporting the upper and lower ends of the needle roller bearing through the thrust washer and the support ring, the squeeze phenomenon of the needle roller bearing It is an object of the present invention to provide a propeller shaft structure of a vehicle that can prevent and thus increase the durability of a spider.
상기와 같은 목적을 달성하기 위한 본 발명은, 유니버설 조인트와 플랜지 요크의 결합시 사용되는 스파이더의 각 단부에는 니들롤러베어링이 끼워져서 결합되고, 상기 니들롤러베어링은 베어링캡에 의해 감싸여져 보호되며, 상기 베어링캡의 하단은 실에 의해 밀봉되어지는 자동차의 프로펠러샤프트 구조에 있어서, 상기 니들롤러베어링의 상단과 상기 베어링캡사이에 설치되어 상기 니들롤러베어링의 상단을 지지하는 스러스트와셔와, 상기 니들롤러베어링의 하단과 상기 실사이에 형성된 여유공간으로 설치되어 상기 니들롤러베어링의 하단을 지지하는 서포트링과, 상기 베어링캡의 하단과 상기 스파이더의 외주면에 지지되도록 설치되어 상기 실을 보호하는 실가아더를 더 포함하여 구성되는 것을 특징으로 한다.The present invention for achieving the above object, the needle roller bearing is fitted to each end of the spider used in the coupling of the universal joint and the flange yoke, the needle roller bearing is wrapped and protected by a bearing cap, The lower end of the bearing cap is a propeller shaft structure of a vehicle that is sealed by a seal, the thrust washer is installed between the upper end of the needle roller bearing and the bearing cap to support the upper end of the needle roller bearing, the needle roller A support ring for supporting the lower end of the needle roller bearing, which is installed with a clearance formed between the lower end of the bearing and the seal, and a sealer that is installed to be supported on the lower end of the bearing cap and the outer circumferential surface of the spider to protect the seal. Characterized in that it comprises a.
이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 2는 본 발명에 따른 프로펠러샤프트 구조를 설명하기 위한 부분적인 종단면도로서, 종래 구조와 동일한 부위에는 동일한 참조부호를 붙이면서 설명하기로 한다.Figure 2 is a partial longitudinal cross-sectional view for explaining the propeller shaft structure according to the present invention, will be described with the same reference numerals to the same parts as the conventional structure.
본 발명에 따라 변속기의 토크를 종감속장치로 전달하는 프로펠러샤프트는 도 2에 도시된 바와 같이 다수의 유니버설 조인트(1) 및 플랜지 요크(2)가 사용되며, 또한 전장이 축의 길이방향으로 가변되는 본 발명에 따른 슬립조인트(3; 도1에 도시됨)도 함께 적용된다. Propeller shaft for transmitting the torque of the transmission to the longitudinal deceleration device according to the invention is a plurality of universal joints (1) and flange yoke (2) is used as shown in Figure 2, the overall length is variable in the longitudinal direction of the shaft The slip joint 3 (shown in FIG. 1) according to the invention also applies.
여기서, 상기 유니버설 조인트(1)와 플랜지 요크(2)는 일명 십자축이라고 불리우는 스파이더(4;spider)에 의해 서로의 결합이 이루어지게 된다.Here, the universal joint 1 and the flange yoke 2 are coupled to each other by a spider 4 called a cross axis.
즉, 상기 스파이더(4)의 각 단부(네개의 축)에는 니들롤러베어링(41)이 끼워져서 결합되고, 상기 니들롤러베어링(41)은 베어링캡(42)에 의해 감싸여져 보호되게 되며, 상기 베어링캡(42)의 하단은 실(43)에 의해 밀봉되는 구조로 되어 있다.That is, the needle roller bearings 41 are fitted to each end (four shafts) of the spider 4, and the needle roller bearings 41 are wrapped and protected by the bearing caps 42. The lower end of the bearing cap 42 is sealed by the seal 43.
그리고, 본 발명에 따른 프로펠러샤프트는 도시된 바와 같이 상기 니들롤러베어링(41)의 상단과 상기 베어링캡(42)사이에 설치되어 상기 니들롤러베어링(41)의 상단을 지지하는 스러스트와셔(46)와, 상기 니들롤러베어링(41)의 하단과 상기 실(43)사이에 형성된 여유공간(C)으로 설치되어 상기 니들롤러베어링(41)의 하단을 지지하는 서포트링(47)과, 상기 베어링캡(42)의 하단과 상기 스파이더(4)의 외주면에 지지되도록 설치되어 상기 실(43)을 보호하는 실가아더(48)를 더 포함하여 구성된다.And, the propeller shaft according to the present invention is installed between the upper end of the needle roller bearing 41 and the bearing cap 42 as shown, the thrust washer 46 supporting the upper end of the needle roller bearing 41 And a support ring 47 installed as a clearance C formed between the lower end of the needle roller bearing 41 and the seal 43 to support the lower end of the needle roller bearing 41, and the bearing cap. It is configured to further include a seal guard 48 installed to support the lower end of the 42 and the outer circumferential surface of the spider 4 to protect the seal 43.
한편, 상기 스러스트와셔(46)에는 니들롤러베어링(41)의 상단을 가압하는 가압돌기부(46a)가 밑면에서부터 아래쪽으로 돌출되게 형성된다.On the other hand, the thrust washer 46 is formed with a pressing protrusion (46a) for pressing the upper end of the needle roller bearing 41 protrudes from the bottom.
그리고, 상기 서포트링(47)은 니들롤러베어링(41)의 하단과 실(43)의 상단에 의해 지지되도록 설치된다.The support ring 47 is installed to be supported by the lower end of the needle roller bearing 41 and the upper end of the seal 43.
따라서, 니들롤러베어링(41)과 베어링캡(42) 및 스러스트와셔(46)등이 결합된 스파이더(4)의 각 단부 중 두개의 축은 도시된 바와 같이 유니버설 조인트(1)의 결합구멍(1a)으로 끼워지고 나머지 두 개의 축은 플랜지 요크(2)의 결합구멍(도시않됨)으로 끼워지게 되며, 이와 같이 유니버설 조인트(1)의 결합구멍(1a)과 플랜지 요크(2)의 결합구멍으로 끼워진 스파이더(4)의 축은 각각 스냅링(44)에 의해 고정되어지게 된다.Accordingly, two axes of each end of the spider 4, to which the needle roller bearing 41, the bearing cap 42, the thrust washer 46, and the like are coupled, have the coupling holes 1a of the universal joint 1 as shown. And the other two shafts are fitted into the engaging holes (not shown) of the flange yoke 2, and thus the spiders fitted into the engaging holes 1a of the universal joint 1 and the engaging holes of the flange yoke 2 The shaft of 4) is to be fixed by the snap ring 44, respectively.
상기와 같은 프로펠러샤프트의 구조는 니들롤러베어링(41)의 상하단이 스러스트와셔(46) 및 서포트링(47)에 의해 지지되어 유동이 불가능한 구조이므로, 상기 니들롤러베어링(41)의 소착현상을 미리 예방할 수 있게 되고, 이에 따라 스파이더(4)의 내구성을 증대시킬 수 있는 잇점이 있게 된다.Since the structure of the propeller shaft as described above is a structure in which the upper and lower ends of the needle roller bearing 41 are supported by the thrust washer 46 and the support ring 47, the flow of the needle roller bearing 41 is prevented. This can be prevented, and thus there is an advantage that can increase the durability of the spider (4).
이상 설명한 바와 같이 본 발명에 의하면, 프로펠러샤프트를 구성하는 니들롤러베어링이 스러스트와셔 및 서포트링에 의해 지지되어 유동이 불가능하게 됨으로써, 상기 니들롤러베어링의 소착현상이 예방되게 되고, 이로 인해 스파이더의 내구성이 증대되는 효과가 있게 된다.As described above, according to the present invention, the needle roller bearing constituting the propeller shaft is supported by the thrust washer and the support ring, thereby making the flow impossible, thereby preventing the squeeze of the needle roller bearing, and thereby the durability of the spider. This increases the effect.
