Description

프로펠러 샤프트의 센터 베어링 장착구조{connective structure for center bearing of propeller shaft}Connective structure for center bearing of propeller shaft

본 발명은 자동차의 프로펠러 샤프트를 지지하는 센터 베어링에 관한 것으로서, 특히 센터 베어링과 크로스 멤버 사이를 연결하는 볼트의 내구성을 증대시킬 수 있고 센터 베어링이 크로스 멤버에서 이탈되는 것을 방지할 수 있는 프로펠러 샤프트의 센터 베어링 장착구조에 관한 것이다.The present invention relates to a center bearing for supporting a propeller shaft of an automobile, and more particularly, to a propeller shaft which can increase the durability of a bolt connecting the center bearing and the cross member and prevent the center bearing from being detached from the cross member. It relates to a center bearing mounting structure.

일반적으로 프로펠러 샤프트는 기관의 동력을 변속기를 거쳐 뒤차축에 전달하는 동력전달기구로서, 자유로운 동력전달을 위해 양 끝에 유니버셜 조인트가 설치되어 있고 길이변화에 대응하기 위해 슬리이브 조인트가 설치되어 있다.In general, the propeller shaft is a power transmission mechanism for transmitting engine power to the rear axle through a transmission, and universal joints are installed at both ends for free power transmission, and sleeve joints are installed to cope with the change in length.

그리고 프로펠러 샤프트의 길이가 긴 대형차일 경우 추진축을 2개 또는 3개로 나누고 각 샤프트의 뒷부분을 센터 베어링으로 프레임의 크로스 멤버에 지지하는 구조로 되어 있다.In the case of a large vehicle with a long propeller shaft, the propulsion shaft is divided into two or three shafts, and the rear portion of each shaft is supported by the cross member of the frame as a center bearing.

즉, 종래 기술에 따른 도 1에 도시된 바와 같이, 변속기(2)와 전방 프로펠러 샤프트(4)가 연결되고, 종감속기어(8)와 후방 프로펠러 샤프트(6)가 연결된 상태에서 전방 프로펠러 샤프트(4)와 후방 프로펠러 샤프트(6)는 유니버셜 조인트(10)로 연결되어 있고, 전방 프로펠러 샤프트(4)의 뒷부분에 센터 베어링(12)이 설치되어 있다.That is, as shown in FIG. 1 according to the related art, the transmission 2 and the front propeller shaft 4 are connected, and the front deceleration gear 8 and the rear propeller shaft 6 are connected to the front propeller shaft ( 4) and the rear propeller shaft 6 are connected by the universal joint 10, and the center bearing 12 is provided in the rear part of the front propeller shaft 4. As shown in FIG.

이 센터 베어링(12)은 전방 프로펠러 샤프트(4)를 회전 가능하게 지지하는 상태로 두 개의 볼트(14)에 의해 프레임의 크로스 멤버(16)에 고정된다. 즉, 크로스 멤버(16)의 하측면에 센터 베어링(12)을 밀착시킨 상태에서 하방에서 상방향으로 두 개의 볼트(14)를 체결하여 고정시킨다.The center bearing 12 is fixed to the cross member 16 of the frame by two bolts 14 in a state rotatably supporting the front propeller shaft 4. That is, in the state in which the center bearing 12 is in close contact with the lower side of the cross member 16, the two bolts 14 are fastened and fixed downward from above.

그러나, 상기와 같이 이루어지는 종래 기술에 따른 프로펠러 샤프트의 센터 베어링 장착구조는 프로펠러 샤프트 지지하중이 두 개의 볼트에 집중되기 때문에 장시간 사용으로 인한 볼트의 피로파단으로 프로펠러 샤프트가 크로스 멤버로부터 떨어지는 문제점이 있다.However, the center bearing mounting structure of the propeller shaft according to the prior art made as described above has a problem in that the propeller shaft falls from the cross member due to fatigue failure of the bolt due to prolonged use because the propeller shaft support load is concentrated on two bolts.

더 나아가, 프로펠러 샤프트가 이탈될 경우 그 회전 진동을 인하여 타부품을 손상시키고, 차량 전복과 같은 대형사고를 초래할 수 있는 문제점이 있다.Furthermore, when the propeller shaft is separated, there is a problem that damages other parts due to the rotational vibration and may cause a large accident such as vehicle overturning.

본 발명은 상기한 문제점을 해결하기 위하여 창출된 것으로서, 본 발명의 목적은 센터 베어링을 크로스 멤버에 고정시키는 볼트에 걸리는 하중을 최소화하여 볼트의 내구성 증대 및 프로펠러 샤프트의 이탈을 방지할 수 있는 프로펠러 샤프트의 센터 베어링 장착구조를 제공하는 데 있다.The present invention has been made to solve the above problems, an object of the present invention is to minimize the load on the bolt that secures the center bearing to the cross member to increase the durability of the bolt and to prevent the propeller shaft from falling off the propeller shaft To provide a center bearing mounting structure.

상기한 과제를 실현하기 위한 본 발명은 전방 프로펠러 샤프트의 일측에 센터 베어링의 베어링부가 끼워지고, 상기 베어링부의 외주연을 설치된 장착부의 양 끝부분이 외측방향으로 절곡되고, 이 장착부의 절곡된 부분이 크로스 멤버에 형성된 띠홈에 끼워지고, 장착부와 크로스 멤버 사이를 볼트로 고정하여 결합되어짐을 특징으로 한다.According to the present invention for realizing the above object, the bearing portion of the center bearing is fitted on one side of the front propeller shaft, both ends of the mounting portion provided with the outer circumference of the bearing portion are bent in the outward direction, and the bent portion of the mounting portion is It is fitted to the band groove formed in the cross member, characterized in that the coupling between the mounting portion and the cross member by fixing with a bolt.

이하, 첨부된 도면을 참조하여 본 발명의 일실시예를 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings.

도 2는 본 발명에 따른 프로펠러 샤프트의 센터 베어링 장착구조를 나타낸 사시도이다.Figure 2 is a perspective view showing a center bearing mounting structure of the propeller shaft according to the present invention.

프로펠러 샤프트는 대형차의 경우 그 길이가 긴 것이 사용되는데, 이러한 경우 프로펠러 샤프트를 2개 또는 3개로 분리하여 연결하고, 각 샤프트의 연결부에는 센터 베어링이 설치되어 프로펠러 샤프트의 하중을 지지한다. 본 실시예에서는 2 개로 분리된 프로펠러 샤프트의 경우를 설명하기로 한다.In the case of large vehicles, the propeller shaft has a long length. In this case, two or three propeller shafts are separated and connected, and a center bearing is installed at the connection portion of each shaft to support the load of the propeller shaft. In the present embodiment will be described the case of two separate propeller shaft.

이러한 프로펠러 샤프트(4,6)는 변속기(2)와 연결되어 변속기(2)의 회전동력을 전달받는 전방 프로펠러 샤프트(4)와 종감속기어(8)와 연결되어 회전동력을 종감속기어(8)로 전달하는 후방 프로펠러 샤프트(6)로 이루어지고, 양 프로펠러 샤프트(4,6)는 유니버셜 조인트(10)로 연결되며, 전방 프로펠러 샤프트(4)의 뒷부분에 샤프트를 지지하는 센터 베어링(30)이 설치된다.The propeller shafts 4 and 6 are connected to the transmission 2 so as to be connected to the front propeller shaft 4 and the reduction gear 8 to receive the rotational power of the transmission 2, thereby reducing the rotational power to the reduction gear 8. A center bearing 30 supporting the shaft at the rear of the front propeller shaft 4, wherein the propeller shafts 4 and 6 are connected to the universal joint 10, and the rear propeller shafts 6 are transmitted to This is installed.

센터 베어링(30)은 도 3에 도시된 바와 같이, 전방 프로펠러 샤프트(4)의 뒷부분에 회전 가능하게 끼워지는 베어링부(34)와 이 베어링부(34)를 크로스 멤버(32)에 고정시키는 장착부(36)로 구성된다. 즉, 장착부(36)는 원통상의 베어링부(34) 외주연에 감싸진 상태로 양쪽으로 연장된 끝부분이 외측방향으로 절곡되어 그 부분이 크로스 멤버(32)에 볼트(52)로 고정된다.As shown in FIG. 3, the center bearing 30 includes a bearing portion 34 rotatably fitted to the rear portion of the front propeller shaft 4 and a mounting portion for fixing the bearing portion 34 to the cross member 32. It consists of 36. That is, the mounting portion 36 is wrapped around the outer peripheral portion of the cylindrical bearing portion 34, the ends extending in both sides is bent in the outward direction and the portion is fixed to the cross member 32 with bolts 52. .

그리고 크로스 멤버(32)에는 센터 베어링의 장착부(36)가 끼워지도록 길이방향의 직각으로 후방측에서 전방측으로 띠홈(40)이 형성된다. 즉, 장착부(36)의 양쪽 절곡부위가 크로스 멤버의 띠홈(40)에 삽입된 상태에서 볼트(52)로 고정된다.And the band member 40 is formed in the cross member 32 from the rear side to the front side at right angles of a longitudinal direction so that the mounting part 36 of a center bearing may be fitted. That is, both bent portions of the mounting portion 36 are fixed with the bolts 52 while being inserted into the band groove 40 of the cross member.

좀 더 자세히 설명하면, 크로스 멤버(32)에는 후방측이 개구된 두 개의 띠홈(40)이 형성되고, 센터 베어링(30)의 장착부(36) 양 끝부분을 후방에서 전방을 향하도록 끼운 뒤 볼트(34)로 고정시킨다.In more detail, the cross member 32 is formed with two band grooves 40 having the rear side open, and then inserting both ends of the mounting portion 36 of the center bearing 30 so that the bolts face forward from the rear side. Fix it with (34).

이때, 센터 베어링의 장착부(36)가 크로스 멤버(32)의 상측면에 얹혀진 상태로 되기 때문에 장착부(36)에 프로펠러 샤프트(4,6)를 지지하는 하중이 작용한다.At this time, since the mounting portion 36 of the center bearing is placed on the upper side of the cross member 32, a load supporting the propeller shafts 4 and 6 acts on the mounting portion 36.

그리고, 크로스 멤버(32)에 형성되는 띠홈(40)은 전방측이 개구된 상태로 되어 센터 베어링의 장착부(36)를 끼워 넣는 방향이 전방에서 후방을 향하도록 이루어져 후방 프로펠러 샤프트(6)의 스플라인 조인트가 이탈되는 것을 방지한다.Then, the band groove 40 formed in the cross member 32 is in a state in which the front side is opened so that the direction in which the mounting portion 36 of the center bearing is fitted is from the front to the rear, and the spline of the rear propeller shaft 6 is formed. To prevent the joint from falling off.

따라서, 상기와 같이 구성되고 작용되는 본 발명에 따른 프로펠러 샤프트의 센터 베어링 장착구조는 센터 베어링의 장착부가 크로스 멤버에 얹혀진 상태로 설치되기 때문에 프로펠러 샤프트를 지지하는 하중이 센터 베어링이 작용하므로 볼트의 피로 파단을 방지할 수 있고, 또한 이로 인하여 프로펠러 샤프트의 이탈되는 것을 방지하여 대형사고를 예방할 수 있다.Therefore, since the center bearing mounting structure of the propeller shaft according to the present invention constructed and operated as described above is installed in a state in which the mounting portion of the center bearing is mounted on the cross member, the load supporting the propeller shaft has a center bearing acting so that the fatigue of the bolt Breaking can be prevented, and this also prevents the propeller shaft from falling off, thereby preventing a large accident.
