차량의 리어서브프레임과 서스펜션아암들의 배치구조{Layout of a rear sub-frame and suspension arms of a vehicle}Layout of a rear sub-frame and suspension arms of a vehicle

본 발명은 차량의 리어서브프레임과 이와 인접하게 설치되는 서스펜션 아암들의 배치구조에 관한 것으로서, 보다 상세하게는 차량의 충돌 사고시 연료탱크의 파손 가능성을 저감시키고 차량의 조정안정성을 보다 향상시킬 수 있도록 하는 기술에 관한 것이다.The present invention relates to an arrangement structure of the rear frame of the vehicle and the suspension arms installed adjacent thereto, and more particularly, to reduce the possibility of damage to the fuel tank during the collision of the vehicle and to improve the adjustment stability of the vehicle. It's about technology.

도 1에는 종래 기술에 의한 차량의 리어서브프레임과 서스펜션아암들의 배치상태가 도시되어 있다.Figure 1 shows the arrangement of the rear frame and suspension arms of the vehicle according to the prior art.

리어서브프레임(100)은 마운트부시(102)를 통해 차체의 저면에 장착되며, 상기 리어서브프레임(100)의 측방향으로는 래터럴링크(104)가 차체의 횡방향으로 차륜의 너클(106)과 연결되어 있으며, 상기 너클(106)에는 차량의 전후 방향을 따라 차체에 직접 연결되는 트레일링링크(108)가 연결되어 있는 구조이다.The rear frame 100 is mounted on the bottom surface of the vehicle body through the mount bushing 102, and the lateral link 104 in the lateral direction of the rear frame 100 is the knuckle 106 of the wheel in the transverse direction of the vehicle body. The knuckle 106 has a structure in which a trailing link 108 connected directly to the vehicle body is connected to the vehicle body along the front and rear directions of the vehicle.

그런데, 상기와 같은 상태에서 차량의 주행시에 차륜을 통해 입력되는 충격은 주로 트레일링링크(108)를 통해 차체쪽으로 전달되므로 상기 리어서브프레임(100)이 차량의 승차감을 개선하는 데에는 큰 도움을 주지 못한다.However, in the above state, the impact input through the wheels while driving the vehicle is mainly transmitted to the vehicle body through the trailing link 108, so that the rear frame 100 does not help greatly in improving the riding comfort of the vehicle. can not do it.

한편, 차량의 선회 주행시에 차륜으로부터 작용하는 하중은 상기 래터럴링크(104)를 통해 작용하는데, 이 하중에 대해 상기 리어서브프레임(100)은 그 지지구조가 변형이 가능한 마운트부시(102)에 의해 차체에 마운팅되어 있는 상태이어서, 상기 마운트부시(102)가 변형되면서 상기 래터럴링크(104)로부터 입력되는 하중을 적절히 지지하지 못하므로 차량의 횡강성 및 조종 안정성에 불리하게 작용하는 문제점을 가지고 있다.On the other hand, the load acting from the wheel during the turning run of the vehicle is acting through the lateral link 104, the reversal frame 100 against the load by the mount bush 102, the support structure is deformable Since the mount bushing 102 is deformed and does not properly support the load input from the lateral link 104, the mount bushing 102 may be detrimentally affected by the lateral stiffness and steering stability of the vehicle.

한편, 도 2와 도 3에는 상기한 바와 같은 리어서브프레임(100)과 이에 인접한 위치에 장착되어 있는 부품들과의 관계가 도시되어 있는바, 리어서브프레임(100)의 후방에는 보조타이어(110)가 위치하고 있고, 리어서브프레임(100)의 전방에는 연료탱크(112)가 위치하고 있다.Meanwhile, FIG. 2 and FIG. 3 show a relationship between the rear subframe 100 and the components mounted at positions adjacent to the rear subframe 100, and the auxiliary tire 110 is located at the rear of the rear subframe 100. ) Is located, and the fuel tank 112 is located in front of the rear frame (100).

따라서, 도 2와 도 3의 우측에 각각 도시된 바와 같이 차량의 후방에서 충돌 사고가 발생할 때에는 상기 보조타이어(110)와 리어서브프레임(100)이 전방으로 밀리면서 연료탱크(112)를 파손시키기 용이한 상태이다.Therefore, as shown in the right side of FIG. 2 and FIG. 3, when the collision accident occurs in the rear of the vehicle, the auxiliary tire 110 and the rear frame 100 are pushed forward to damage the fuel tank 112. It is an easy state.

이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 차량의 승차감과 조종안정성을 향상시키도록 서스펜션아암의 배치를 변경하고 후방충돌 사고시에도 연료탱크의 파손 가능성을 대폭적으로 저감시킬 수 있도록 한 차량의 리어서브프레임과 서스펜션아암들의 배치구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the problems described above, so as to change the arrangement of the suspension arm to improve the ride comfort and steering stability of the vehicle and to significantly reduce the possibility of damage to the fuel tank in the event of a rear collision. The object is to provide an arrangement of the rear frame and suspension arms of a vehicle.

상기한 바와 같은 목적을 달성하기 위한 본 발명 차량의 리어서브프레임과 서스펜션아암들의 배치구조는 연료탱크의 전방에 설치된 리어서브프레임과;Arrangement structure of the rear frame and the suspension arm of the vehicle of the present invention for achieving the above object is a rear frame installed in front of the fuel tank;

상기 리어서브프레임과 너클을 연결하도록 차체의 전후방향으로 설치된 트레일링링크와;A trailing link installed in the front and rear directions of the vehicle body to connect the rear frame and the knuckle;

너클을 차량의 횡방향으로 차체에 연결하여 지지하는 래터럴링크로 구성된 것을 특징으로 한다.And a lateral link that connects and supports the knuckle to the vehicle body in the transverse direction of the vehicle.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

도 4는 본 발명에 따른 차량의 리어서브프레임과 서스펜션아암들의 배치구조를 도시한 것으로서, 리어서브프레임(1)을 연료탱크(3)의 전방에 설치하고 있으며, 트레일링링크(5)를 차체의 전후 방향으로 상기 리어서브프레임(1)과 너클(7)의 사이에 연결하고, 래터럴링크(9)를 차량의 횡방향으로 연결하여 너클(7)을 지지하도록 하고 있다.Figure 4 shows the arrangement of the rear frame and suspension arms of the vehicle according to the invention, the rear frame (1) is installed in front of the fuel tank (3), the trailing link (5) to the body The rear frame 1 and the knuckle 7 are connected in the forward and backward directions of the lateral link, and the lateral link 9 is connected in the lateral direction of the vehicle so as to support the knuckle 7.

여기서, 상기 서스펜션아암들이라 함은 상기 트레일링링크(5) 및 래터럴링크(9)를 말한다.Here, the suspension arms refer to the trailing link 5 and the lateral link 9.

상기 리어서브프레임(1)은 양단이 후방으로 돌출된 형상으로 대략 “U”자 형으로 형성되어 설치되며, 상기 리어서브프레임(1)을 차체에 마운팅하는 마운팅부시(11)는 리어서브프레임(1)의 양측에서 차량의 전후 방향으로 배치되어 있다.The rear frame 1 is formed to have a substantially “U” shape in which both ends protrude rearward, and a mounting bush 11 for mounting the rear frame 1 to the vehicle body has a rear frame ( It is arrange | positioned in the front-back direction of a vehicle from both sides of 1).

상기 트레일링링크(5)는 상기 리어서브프레임(1)의 전후 방향으로 배치된 마운팅부시(11)의 사이에 별도의 부시(13)에 의해 연결되어 있고, 상기 래터럴링크(9)도 별도의 부시(15)에 의해 차체에 직접 연결되어 있다.The trailing link 5 is connected by a separate bush 13 between the mounting bushes 11 arranged in the front-rear direction of the rear frame 1, and the lateral link 9 is also separate. The bush 15 is directly connected to the vehicle body.

상기한 바와 같이 구성된 본 발명의 작용을 살펴보면 다음과 같다.Looking at the operation of the present invention configured as described above are as follows.

차량의 주행시 차륜을 통해 작용하는 각종 충격 하중은 상기 트레일링링크(5)를 통해 상기 리어서브프레임(1)으로 전해지고, 상기 리어서브프레임(1)은 상기 마운트부시(11)에 의해 차체에 진동이 절연된 상태로 연결되어 있으므로, 차량의 주행중 차체로 전달되는 충격이 현저히 저감되어 차량은 승차감이 개선된다.Various impact loads acting on the wheels while driving the vehicle are transmitted to the rear frame 1 through the trailing link 5, and the rear frame 1 vibrates to the vehicle body by the mount bush 11. Since it is connected in this insulated state, the shock transmitted to the vehicle body while the vehicle is running is significantly reduced, and the ride comfort of the vehicle is improved.

아울러, 차량이 선회주행을 하는 경우에는 횡력이 상기 래터럴링크(9)로 작용하게 되는데, 상기 래터럴링크(9)는 그 일단이 차체에 직접 연결되어 있는 구조이어서, 상기 하중에 대하여 종래보다 견고한 지지력으로 지탱하므로 횡강성이 증대되어 차량의 조종안정성을 향상시키게 된다.In addition, when the vehicle is turning, the lateral force acts as the lateral link 9. The lateral link 9 has a structure in which one end thereof is directly connected to the vehicle body, and thus a stronger supporting force than the conventional load. Since the lateral stiffness is increased, the steering stability of the vehicle is improved.

한편, 상기한 바와 같이 리어서브프레임(1)이 연료탱크(3)의 전방으로 위치됨에 따라서, 종래에 비하여 상기 보조타이어와 상기 연료탱크 사이에 충격을 완충 및 흡수할 충분한 공간이 형성되어 있는 상태이므로, 차량의 후방 충돌시 충돌에 의한 충격을 상기 공간에서 흡수하여, 연료탱크(3)에는 영향이 미치지 않도록 함으로써, 연료탱크(3)의 파손 위험성을 대폭적으로 저감시키게 된다.On the other hand, as described above, as the rear frame 1 is positioned in front of the fuel tank 3, a state where sufficient space is provided between the auxiliary tire and the fuel tank to cushion and absorb shocks as compared with the conventional art. Therefore, the shock caused by the collision at the time of the rear collision of the vehicle is absorbed in the space so that the fuel tank 3 is not affected, thereby greatly reducing the risk of damage to the fuel tank 3.

이상과 같이 본 발명에 의하면, 리어서브프레임을 연료탱크의 전방에 위치시키고 트레일링링크와 래터럴링크의 차체측 연결구조를 변경함으로써, 차량의 승차감과 조종안정성을 향상시키고, 차량의 후방 충돌 사고시에도 연료탱크의 파손 가능성을 대폭적으로 저감시킬 수 있도록 한다.As described above, according to the present invention, by positioning the rear frame in front of the fuel tank and changing the body-side connection structure of the trailing link and the lateral link, it is possible to improve the ride comfort and steering stability of the vehicle, even in the event of a rear collision of the vehicle. It is possible to greatly reduce the possibility of damage to the fuel tank.
