본 발명은 차량의 후륜 서스펜션에 설치되는 커플드 토션빔 액슬(Coupled Torsion Beam Axle)의 기본 형상을 유지하면서 차량의 좌우 방향 및 상하 방향으로의 하중 발생에 따른 충격을 흡수하여 전체적인 차량의 횡 강성이 증대 가능하도록 복수개의 댐핑 러버를 구비하여 차량의 좌우 방향 및 상하 방향에서 차체를 향해 전달되는 충격을 흡수하고 횡 강성에 대한 안정적인 지지가 가능한 차량용 커플드 토션빔 액슬 장치에 관한 것이다.The present invention maintains the basic shape of the coupled torsion beam axle (Coupled Torsion Beam Axle) installed in the rear wheel suspension of the vehicle absorbs the impact of the load generated in the left and right direction and the vertical direction of the vehicle so that the overall lateral rigidity of the vehicle The present invention relates to a coupled torsion beam axle device for a vehicle, which includes a plurality of damping rubbers so as to be able to increase, absorbs the shock transmitted to the vehicle body in the left and right directions and the up and down direction of the vehicle and enables stable support for the lateral rigidity.

일반적으로 차량에 구비되는 현가장치는 차축과 차체 사이를 연결시켜 주행중에 차축이 노면으로부터 받는 진동이나 충격 등을 적절히 감쇠시켜 차체의 손상과 탑승자의 승차감을 향상시킬 수 있도록 하는 장치이다.In general, a suspension device provided in a vehicle is a device that connects the axle and the vehicle body to attenuate vibrations or shocks received from the road surface while driving, thereby improving damage to the vehicle body and riding comfort of the occupant.

상기한 현가장치 중에 커플드 토션빔 액슬(Coupled Torsion Beam Axle)은 간단한 구조로 생산단가가 저렴하고 작은 질량에 비하여 상대적으로 높은 주행 안정성을 갖고 있어서 오랫동안 경차 및 준중형 차량의 후륜 현가장치로 사용되어 오고 있다.Coupled Torsion Beam Axle among the above-mentioned suspensions has been used as a rear suspension of light and semi-medium sized vehicles for a long time because of its simple structure and low production cost and relatively high running stability compared to small mass. have.

종래의 커플드 토션빔 액슬(Coupled Torsion Beam Axle)의 구조를 살펴보면 상하방향의 하중을 지지하는 스프링과 쇼바와 좌우 방향의 하중을 지지하는 커플드 토션빔 액슬(CTBA)으로 이루어져 있다. 상기와 같이 이루어진 종래의 커플드 토션빔 액슬 구조는 차량의 주행이 이루어지면서 지면으로부터 타이어를 통해 차체로 전달되는 상하 하중 발생시에는 스프링과 쇼바가 압축 변형이 발생 되면서 차체에 전달되는 하중을 흡수하고 있으며, 차량의 좌우 방향으로 하중 발생시에는 커플드토션빔액슬에서 변형이 발생 되어 차체에 전달되는 충격을 흡수하도록 작동된다.Looking at the structure of a conventional coupled torsion beam axle (Coupled Torsion Beam Axle) consists of a spring for supporting the load in the up and down direction, and a coupled bar and a coupled torsion beam axle (CTBA) for supporting the load in the left and right directions. The conventional coupled torsion beam axle structure made as described above absorbs the load transmitted to the vehicle body by the compression deformation of the spring and the shock bar when the up and down load is transmitted from the ground to the vehicle body while the vehicle is traveling. When the load is generated in the left and right directions of the vehicle, deformation is generated in the coupled torsion beam axle, and the shock is transmitted to the vehicle body.

그러나, 종래의 커플드 토션빔 액슬 구조는 실제로 차량의 좌우 방향으로 하중이 발생될 경우에 커플드 토션빔 액슬에 변형이 발생 되어 차량의 조종안정성에 문제가 발생 되며 제동시 뒷바퀴에서 회전이 일어나는 심각한 문제점을 안고 있었다.However, the conventional coupled torsion beam axle structure is deformed to the coupled torsion beam axle when the load is actually generated in the left and right directions of the vehicle, which causes problems in the steering stability of the vehicle and severe rotation occurs in the rear wheel during braking. I had a problem.

이로 인해 여성 운전자나 초보 운전자의 경우에는 안정적인 차량 주행에 어려움을 유발하여 이에 대한 시금한 대책을 필요로 했다.As a result, it is difficult for female drivers and novice drivers to cause stable vehicle driving and require urgent countermeasures.

상기와 같이 구성되는 본 발명에 의한 차량용 커플드 토션빔 액슬 장치의 실시예를 도면을 참조하여 설명한다.An embodiment of a coupled torsion beam axle device for a vehicle according to the present invention configured as described above will be described with reference to the drawings.

첨부된 도 1은 본 발명에 의한 차량용 커플드 토션빔 액슬 장치를 도시한 도 면이고, 도 2는 본 발명에 의한 차량용 커플드 토션빔 액슬 장치의 작동 상태도이다.1 is a view illustrating a coupled torsion beam axle device for a vehicle according to the present invention, and FIG. 2 is an operation state diagram of the coupled torsion beam axle device for a vehicle according to the present invention.

첨부된 도 1 내지 도 2를 참조하면, 차량의 후륜에 설치되는 커플드 토션빔 액슬(100)의 상측으로 각각 수평하게 이격 설치되며 차량의 좌우 방향 및 상하 방향으로의 하중 발생에 따른 충격을 흡수하여 횡 강성이 증대 가능하도록 좌, 우 양방향으로 벌림 각도(θ)를 갖으며 설치되는 댐핑부(200)가 구비되도록 구성된다.1 and 2, horizontally spaced apart from the upper side of the coupled torsion beam axle 100 installed on the rear wheel of the vehicle, and absorbs the impact of the load generated in the left and right direction and the vertical direction of the vehicle. The damping unit 200 is provided to have a spreading angle θ in both left and right directions so that the stiffness can be increased.

상기 댐핑부(200)는 커플드 토션빔 액슬(100)의 상면에 고정 설치되는 장착 브라켓(210)과, 상기 장착 브라켓(210)의 상면에 하측을 향해 좌, 우 대칭으로 절곡된 지지 플레이트(220)와, 상기 지지 플레이트(220)의 상면에 각각 설치되는 댐핑 러버(230)와, 상기 댐핑 러버(230)의 상면에 밀착 설치되며 고정 볼트(10)에 의해 상기 지지 플레이트(220)를 향해 가압 되어 댐핑 러버(230)의 이탈을 방지하는 고정 플레이트(240)를 포함하여 구성된다.The damping unit 200 includes a mounting bracket 210 fixed to an upper surface of the coupled torsion beam axle 100 and a support plate bent in left and right symmetry downward on the upper surface of the mounting bracket 210 ( 220, a damping rubber 230 installed on the upper surface of the support plate 220, and a close contact with the upper surface of the damping rubber 230, and are fixed toward the support plate 220 by fixing bolts 10. It is configured to include a fixing plate 240 is pressed to prevent the escape of the damping rubber 230.

상기 지지 플레이트(220)에 설치되는 댐핑 러버(230)의 두께는 동일한 두께를 갖도록 설치되며, 상기 지지 플레이트(220)와 고정 플레이트(240) 상에 복수개가 설치 가능하도록 이루어진다. 또한, 상기 댐핑 러버(230)가 복수개 설치될 경우에는 댐핑 러버(230) 사이에 별도의 삽입 플레이트(250)를 설치하여 사용할 수 있다. 상기 댐핑 러버(230)의 크기는 고정 플레이트(240)의 크기를 넘지않는 크기를 갖는 것이 바람직하다.The thickness of the damping rubber 230 installed on the support plate 220 is installed to have the same thickness, and a plurality of damping rubbers 230 are installed on the support plate 220 and the fixing plate 240. In addition, when a plurality of the damping rubber 230 is installed, it is possible to install a separate insertion plate 250 between the damping rubber 230. The damping rubber 230 preferably has a size not exceeding the size of the fixing plate 240.

상기 댐핑부(200)의 벌림 각도(θ)는 90°의 각도 범위를 갖는 것이 바람직하다. 즉, 지지 플레이트(220)의 중앙을 기준으로 양측으로 각각 45°씩 벌어지도 록 설치되는 것이 차량의 좌, 우 방향에서 하중이 가해질 때 안정적으로 댐핑이 이루어지기 때문이다.The spreading angle θ of the damping unit 200 preferably has an angle range of 90 °. That is, the damping is made stable when the load is applied in the left and right directions of the vehicle so as to be widened at 45 ° on both sides with respect to the center of the support plate 220.

상기와 같이 구성되는 차량용 커플드 토션빔 액슬 장치의 작동 상태를 도면을 참조하여 설명한다.An operating state of the coupled torsion beam axle device for a vehicle configured as described above will be described with reference to the drawings.

첨부된 도 1 내지 도 2를 참조하면, 차량에 운전자를 포함한 탑승객이 탑승한 상태에서 도로를 따라 주행이 이루어지면서 도로의 지면 상태에 따라 차량의 상하 또는 좌우 방향에서 충격이 전달된다.1 to 2, the driving is performed along the road in a state where a passenger including a driver rides in the vehicle, and the shock is transmitted in the up and down or left and right directions of the vehicle according to the ground state of the road.

도로의 지면 상태가 불균일하지 않은 안정적인 상태에서는 차량의 좌우 방향으로 발생되는 하중의 빈도는 상하 방향으로 발생되는 하중에 비해 상대적으로 적어지게 되며 타이어(2)를 통해 커플드 토션빔 액슬(100)에 전달된다.In a stable state in which the ground condition of the road is not uneven, the frequency of the load generated in the left and right directions of the vehicle becomes relatively smaller than the load generated in the vertical direction, and is coupled to the coupled torsion beam axle 100 through the tire 2. Delivered.

상기 커플드 토션빔 액슬(100)에 전달된 하중은 수직 상부 방향을 향해 그대로 전달되어 장착 브라켓(210)을 경유하여 댐핑부(200)로 전달된다.The load transmitted to the coupled torsion beam axle 100 is transmitted as it is toward the vertical upper direction and is transmitted to the damping unit 200 via the mounting bracket 210.

상기 댐핑부(200)에서는 타이어(2)를 통해 수직 방향으로 전달된 하중 및 충격이 댐핑 러버(230)를 통과하면서 감쇄되어 차량에 탑승한 탑승객에게 상하 방향으로의 충격을 최소화하게 된다.In the damping unit 200, the load and the impact transmitted in the vertical direction through the tire 2 are attenuated while passing through the damping rubber 230, thereby minimizing the impact in the vertical direction to the passenger in the vehicle.

만약, 도로의 지면 상태가 불균일 하거나 급선회가 이루어지는 경우일 때에는 타이어(2)를 통해 상하 및 좌우 방향 동시에 하중 및 충격이 발생 되어 복합적으로 차체에 전달이 이루어지게 된다. 상기와 같은 경우에는 좌우 방향으로 가해진 하중 및 충격이 1 차적으로 커플드 토션빔 액슬(100)에 전달되어 흡수되고, 댐핑부(200)를 통해 커플드 토션빔 액슬(100)에서 흡수되지 못한 나머지 잔류 하중 및 충격은 댐핑 러버(230)를 통해 감쇄가 이루어지게 된다.When the ground condition of the road is uneven or when sharp turns are made, loads and shocks are generated simultaneously in the vertical and horizontal directions through the tire 2, and the transmission is made to the vehicle body in a complex manner. In such a case, the load and the impact applied in the left and right directions are primarily transmitted to and absorbed by the coupled torsion beam axle 100, and the rest is not absorbed by the coupled torsion beam axle 100 through the damping unit 200. Residual load and impact is attenuated through the damping rubber 230.

첨부된 도 2를 참조하면, 상하 하중 및 좌우 하중 발생에 따라 댐핑부(200)에서의 벡터관계를 살펴보면 상하방향으로의 하중 및 충격을 Fkz라 하고, 좌우 방향으로의 하중 및 충격을 Fky라 할 경우에 각각의 합 벡터는 Fk(댐핑 러버의 탄성력) 방향으로 작용하게 된다.Referring to FIG. 2, when looking at the vector relationship in the damping part 200 according to the up and down load and the left and right load generation, the load and the impact in the up and down directions are referred to as Fkz, and the load and the impact in the left and right directions are referred to as Fky. In this case each sum vector acts in the direction of Fk (elastic force of the damping rubber).

따라서, 벌림 각도(θ)를 갖는 지지 플레이트(220)의 상면에 설치된 댐핑 러버(230)를 통해 상하 하중 및 좌우 하중이 감쇄되어 차량에 탑승한 탑승객에게 가해지는 충격을 최소화하게 된다.Therefore, the upper and lower loads and the left and right loads are attenuated through the damping rubber 230 installed on the upper surface of the support plate 220 having the opening angle θ, thereby minimizing the impact on the passengers in the vehicle.

한편, 본 발명은 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능할 것이다. On the other hand, the present invention can be variously modified by those skilled in the art without departing from the gist of the invention.

이상에서 설명한 바와 같이, 본 발명에 따른 차량용 커플드 토션빔 액슬 장치는 차량에 탑승한 운전자 및 탑승객에게 가해지는 상하 방향 및 좌우 방향으로의 진동 및 충격을 최소화하여 승차감을 안정적으로 유지 가능하게 하고, 차량의 전체적인 조정 안정성과 급제동에 따른 차량의 회전을 방지할 수 있는 효과가 있다.As described above, the vehicle coupled torsion beam axle device according to the present invention can minimize the vibration and impact in the vertical direction and the left and right directions applied to the driver and passengers in the vehicle to maintain a ride comfort stably, The overall adjustment stability of the vehicle and there is an effect that can prevent the rotation of the vehicle due to sudden braking.
