Description
본 발명은 차량의 파워유닛 마운트 시스템에 관한 것으로, 특히 엔진을 4점지지로부터 5점지지로 개선시켜 엔진의 롤링운동을 지지하기 위한 장치로서, 엔진을 지지하는 힘의 고른 분산을 통하여 부시류의 내구성능 및 승차감을 향상시킬 수 있도록 한 파워유닛 마운트 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power unit mounting system of a vehicle, and more particularly, to an apparatus for supporting a rolling motion of an engine by improving an engine from a four point support to a five point support. The present invention relates to a power unit mounting system capable of improving durability and riding comfort.
차량의 파워유닛 마운팅장치는 엔진룸내에 장착되는 엔진(트랜스미션 포함)을 차체로부터 지지하기 위한 장치로서, 기본적으로 엔진룸 좌,우측 2지점에서 엔진마운트에 의해 지지되고, 다른 2지점에서 엔진의 롤링운동을 지지하게 되어 있다. 도 3 및 도 4는 종래 서로 다른 방법으로 엔진의 롤링운동을 제어하기 위한 마운팅장치를 도시하고 있다.The power unit mounting device of a vehicle is a device for supporting an engine (including a transmission) mounted in an engine room from a vehicle body, and is basically supported by an engine mount at two points on the left and right sides of the engine room, and rolling the engine at two other points. It is supposed to support movement. 3 and 4 show a mounting apparatus for controlling the rolling motion of the engine in a conventional manner.
도 3은 4점지지방식으로 엔진(트랜스미션 포함)(52)을 양측에서 토크롤축 (23)선상의 엔진마운트(16,17)로 지지하고, 엔진(52)의 상,하부를 일측에서 상부리액션로드(19), 하부리액션로드(18)로 지지하고 있다.FIG. 3 shows the engine (including transmission) 52 supported by the engine mounts 16 and 17 on the torque roll shaft 23 on both sides, and the upper and lower portions of the engine 52 on one side. It is supported by the rod 19 and the lower reaction rod 18.
여기서 엔진(52)의 롤링운동을 지지하기 위한 상부엔진마운트(19)는 일단이 엔진의 상부에 타단이 엔드월(end wall)(21)측에 연결되어 있고, 하부리액션로드 (18)는 일단이 엔진의 하부에 타단이 크로스멤버(23)측에 연결되어 있다.Here, the upper engine mount 19 for supporting the rolling motion of the engine 52 has one end connected to the end wall 21 on the other end of the upper part of the engine, and the lower reaction rod 18 once. The other end is connected to the cross member 23 side in the lower part of this engine.
도 3과 같이 엔진의 롤링운동을 엔드월(21)과 크로스멤버(22)측에서 지지하는 엔진마운팅 방식은 엔진의 롤링시 상부리액션로드(19)가 압축력을 받으면 하부리액션로드(18)는 인장력을 받고, 반대로 상부리액션로드(19)가 인장력을 받으면 하부리액션로드(18)는 압축력을 받는다.As shown in FIG. 3, in the engine mounting method of supporting the rolling motion of the engine at the end wall 21 and the cross member 22, when the upper reaction rod 19 receives a compressive force during rolling of the engine, the lower reaction rod 18 is pulled out. On the contrary, when the upper reaction rod 19 receives a tensile force, the lower reaction rod 18 receives a compressive force.
한편, 도 4도 4점지지 방식으로, 엔진 회전운동을 제어하기 위한 마운팅장치에 있어서는 엔진(52)의 롤링방향에 따라 상부리액션로드(8)가 압축력을 받으면 하부리액션로드(9)도 압축력을 받고, 상부리액션로드(8)가 인장력을 받으면 하부리액션로드(9)도 인장력을 받게 되어 있다.Meanwhile, in the mounting apparatus for controlling the engine rotational motion in the four-point support method of FIG. 4, when the upper reaction rod 8 receives the compression force according to the rolling direction of the engine 52, the lower reaction rod 9 also receives the compression force. When the upper reaction rod 8 receives the tensile force, the lower reaction rod 9 also receives the tensile force.
위에서 살펴본 4점 지지 엔진마운트 방식에서는 상부 및 하부 리액션로드 (reaction rod)가 모두 오른쪽(운전석에서 보았을 경우)에 위치하고 있다.In the four-point support engine mount system discussed above, both the upper and lower reaction rods are located on the right (when viewed from the driver's seat).
이는 크래시(crash) 성능(차량 충돌시 안전정도) 및 패키지 문제를 고려한 설계의 결과이다.This is the result of a design that takes into account crash performance (safety in vehicle crashes) and package issues.
그런데 이러한 설계를 적용할 경우 강체(차체 및 트랜스미션을 포함한 엔진)모드중 바운싱(bouncing) 및 롤링(rolling)(엔진의 크랭크축을 중심으로 발생되는 회전운동)은 비연성으로 지지시킬 수 있으나 엔진의 전후방 및 요잉(yawing)(한쪽으로 치우침)운동이 발생될 가능성이 높다.However, if this design is applied, the bouncing and rolling (rotational movements around the crankshaft of the engine) of the rigid (engines including the body and the transmission) mode can be supported inflexibly, but the front and rear of the engine Yawing movements are more likely to occur.
따라서 엔진마운트를 통한 힘의 분산에서도 효율이 떨어지고, 엔진 마운트를 구성하는 부시류('베어링'이라고도 칭한다)의 내구성을 저하시키는 원인으로 작용하고, 승차감의 향상에도 별 도움을 주지 못하였다.As a result, the efficiency is reduced even when the force is distributed through the engine mount, which acts as a cause of lowering the durability of the bushes (also referred to as bearings) constituting the engine mount, and has not helped to improve the ride comfort.
본 발명은 상기와 같은 사정을 감안하여 창안된 것으로, 5점지지로 개선시켜 엔진의 롤링운동을 제어하기 위한 지지장치로서, 엔진을 지지하는 힘의 고른 분산을 꾀하여 부시류의 내구성능 및 승차감을 향상시킬 수 있도록 한 5점지지 파워유닛 마운트 시스템을 제공함에 그 목적이 있다.The present invention was devised in view of the above circumstances, and is a support device for controlling the rolling motion of the engine by improving it to five-point support.

도 1 및 도 2에서와 같이, 크랭크축(51)이 차체의 횡방향으로 배설된 엔진 (52)과 트랜스미션(54)을 구비한 파워유닛(50)을 차체에 탄성적으로 탑재하기 위한 파워유닛의 마운팅시스템에 있어서, 상기 파워유닛(50)을 제1 및 제2 마운팅 지점으로 탄성지지하기 위해, 파워유닛(50)의 횡방향 양단부가 토크롤축(53)으로 배치된 제1 엔진마운트(61) 및 제2트랜스미션마운트(62)를 매개로 차체의 좌,우측 사이드롱지(71,72)에 탄성지되게 설치되어 있다.1 and 2, the power unit for elastically mounting the power unit 50 having the engine 52 and the transmission 54, the crankshaft 51 is disposed in the transverse direction of the vehicle body; In the mounting system of claim 1, in order to elastically support the power unit 50 to the first and second mounting points, the first engine mount 61 in which the both ends of the power unit 50 in the lateral direction are disposed on the torque roll shaft 53. ) And the second transmission mount 62 are installed on the left and right side longages 71 and 72 of the vehicle body so as to be elastic.
그리고 상기 파워유닛(50)을 제3마운팅 지점으로 탄성지지하기 위해, 일단이 파워유닛(50)의 중심 하부가 되는 엔진(52)측에 연결되고 타단이 차체의 크로스멤버(100)에 연결되는 제3엔진마운트(80)가 설치되어 있다.And in order to elastically support the power unit 50 to the third mounting point, one end is connected to the engine 52 side to be the lower center of the power unit 50 and the other end is connected to the cross member 100 of the vehicle body The third engine mount 80 is provided.
또한 상기 파워유닛(50)을 제4 및 제5마운팅 지점으로 지지하기 위해, 일단이 엔진(52) 및 트랜스미션(54)의 양끝단 상부에 각각 연결되고 타단이 차체의 양측 사이드롱지(71,72)에 각각 연결되는 제4 및 제5엔진마운트(90,110)를 구비하고 있다.In addition, in order to support the power unit 50 to the fourth and fifth mounting points, one end is connected to the upper ends of the engine 52 and the transmission 54, respectively, and the other end is connected to both side longages 71 of the vehicle body. 72 and fourth and fourth engine mounts 90 and 110, respectively.
상기 실시예에서 제1 및 제2엔진 마운트(61,62)의 구성은 주지된 기술이므로 상세한 설명은 생략한다.In the above embodiment, the configurations of the first and second engine mounts 61 and 62 are well known techniques, and thus detailed description thereof will be omitted.
또한 상기 제3내지 제5엔진마운트(80,90,110)는 각각 리액션로드(reaction rod)를 포함하고 있는 것으로, 엔진의 롤링운동 방향에 따라 동시에 리액션로드들이 압축력 또는 인장력을 받게 되어 있다.In addition, the third to fifth engine mounts 80, 90, and 110 each include a reaction rod, and the reaction rods receive a compressive force or a tension force at the same time according to the rolling direction of the engine.
이와 같이 구성된 본 실시예의 작용을 설명한다.The operation of this embodiment configured as described above will be described.
먼저, 차량의 주행중에 받는 바운싱(bouncing)(엔진 상하운동)은 제1 및 제2엔진마운트(61,62)에 의해 지지 완충된다.First, bouncing (engine up and down movement) received while the vehicle is running is supported and buffered by the first and second engine mounts 61 and 62.
한편, 파워유닛(50)의 롤링운동은 3지점을 통하여 탄성지지된다.On the other hand, the rolling motion of the power unit 50 is elastically supported through three points.
먼저 1지점은 파워유닛(50)의 중심 하방인 제3엔진마운트(80)를 통하여 탄성지지되고, 다른 1지점은 트랜스미션(54)의 상부 단부측에 연결된 제4엔진마운트(90)를 통하여 차체에서 탄성지지되고, 나머지 1지점은 엔진(52)의 상부 단부측에 연결된 제5엔진마운트(110)를 통하여 차체에서 탄성지지된다.First, one point is elastically supported through the third engine mount 80, which is below the center of the power unit 50, and the other one point is connected to the upper end side of the transmission 54 by the fourth engine mount 90. The first point is elastically supported in the vehicle body through the fifth engine mount 110 connected to the upper end side of the engine 52.
이때 제4 및 제5엔진 마운트(90,110)는 차체의 사이드롱지(71,72)측에 지지됨으로써 실내로 진동소음이 들어오는 경로를 미연에 방지할 수 있게 된다.In this case, the fourth and fifth engine mounts 90 and 110 are supported on the side longages 71 and 72 of the vehicle body, thereby preventing the path of vibration noise entering the room.
