Description
본 발명은 토션빔 타입 후륜 현가장치에 관한 것으로, 보다 상세하게는 선회시 발생되는 토우-인(Toe-In)을 나타내어 선회안정성을 유지한 차량의 토션빔 타입 후륜 현가장치에 관한 것이다.The present invention relates to a torsion beam type rear wheel suspension device, and more particularly, to a torsion beam type rear wheel suspension device of a vehicle which exhibits a toe-in generated during turning and maintains turning stability.
일반적으로 차량의 서스펜션은 차축과 차체 사이를 연결시켜 주행중에 차축이 노면으로부터 받는 진동이나 충격등을 적절히 감쇠시켜 차체의 손상과 탑승자의 승차감을 향상시킬 수 있도록 된 것이다.In general, the suspension of the vehicle is connected to the axle and the body so as to properly attenuate vibrations or shocks received from the road surface while driving, thereby improving damage to the body and riding comfort of the occupant.
이러한 현가장치중 토션빔 액슬(Torsion Beam Axle)타입 리어서스펜션은 스프링과 쇽업소버를 각각 설치하고 토션빔의 비틀림을 이용하여 양측 차륜의 거동이 최적상태로 이루어지도록 하는데 즉, 토션빔 현가장치는 단순한 부품으로 인하여 설계 성능 범위가 높지 않음에도 불구하고, 낮은 생산 단가와 낮은 질량에 비해 상대적으로 높은 주행 안정성으로 인해 널리 사용되어진다. The torsion beam axle type suspension of these suspensions is provided with springs and shock absorbers, respectively, and by using the torsion of the torsion beams, the two wheels can be operated optimally. Although the range of design performance is not high due to components, they are widely used due to their low production cost and relatively high running stability compared to low mass.
또한, 일반적으로 코너링시 후륜 현가 장치는 언더스티어(understeer)특성을 나타내기 위해서 범핑 조건과 횡력 작용시 모두 토우-인(toe-in) 효과를 나타내도록 설계를 수행 즉, 차량의 코너링시 범핑 조건과 횡력 모두에서 토우-인효과를 나타내어야만 전체적으로 차량이 언더스티어 특성을 가지게 되어 주행 안정성을 높일 수 있는데, 이와 같은 토션빔 현가장치는 중앙에 위치한 토션빔의 토션 변형 특성으로 인하여 차륜의 변형이 이루어지는 특징이 있으며, 이에 따라 토션 변형 및 트레이링 암의 위치 및 부싱 특성에 의해서 롤(roll)시 언더스티어(understeer)로 유도가 가능한 특징이 있음은 물론이다.In addition, in general, the rear wheel suspension device is designed to exhibit a toe-in effect during both bumping and lateral forces in order to exhibit understeer characteristics, i.e., bumping conditions when cornering a vehicle. Only when the toe-in effect is exhibited in both the lateral and the lateral forces, the vehicle has an understeer characteristic as a whole to increase driving stability. Such a torsion beam suspension device is deformed due to the torsional deformation characteristics of the torsion beam located at the center. As a result, the torsional deformation and the position and bushing characteristics of the tracking arm allow the understeer to roll when rolled.
그러나, 이러한 특성에도 불구하고 토션빔 타입의 후륜 현가 장치의 또 다른 특성은 횡력 작용시 토우-아웃(toe-out)의 효과를 발생하게 되는데 즉, 도 3에 도시된 바와 같이 좌회전(left turn)의 경우 바깥쪽 차륜은 오른쪽 바퀴가 되며 이때 횡력의 방향은 y의 방향이 되므로, 횡력시 토우-아웃(toe-out)을 나타나 주행 안정 성능이 감소되는 현상이 있게 된다.However, in spite of this characteristic, another characteristic of the torsion beam type rear wheel suspension is that the effect of toe-out occurs when the lateral force is applied, i.e., left turn as shown in FIG. In the case of the outer wheel is the right wheel, and the direction of the lateral force is the direction of y, so the toe-out during the lateral force (toe-out) is a phenomenon that the driving stability performance is reduced.
이와 같은 현상은 토션빔과 차체사이를 연결하는 부시의 구조상 외력이 집중되어 작용하게 됨으로써 외력 특히, 횡력에 대해서는 상기 부시가 갖는 횡방향 강성만으로는 충분히 대응하기가 곤란한 구조적인 한계성이 있기 때문임은 물론이다.This phenomenon is due to the structural limitations of the bush connecting the torsion beam and the vehicle body to be concentrated, so that there is a structural limitation that is difficult to cope with external force, in particular, the lateral stiffness by the bush alone. to be.
이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 부시를 소정 각도로 틸팅(Tilting)시켜 부시에 작용하는 하중 방향을 차폭 방향으로의 움직임을 최소화해 선회시 토우-아웃 현상을 최대한 억제시켜 조종 안정성을 유지함에 그 목적이 있다.Therefore, the present invention was invented in view of the above, and by tilting the bush at a predetermined angle, the load direction acting on the bush is minimized in the vehicle width direction to minimize the tow-out phenomenon when turning. The purpose is to maintain steering stability.
상기와 같은 목적을 달성하기 위한 본 발명은, 일단이 마운팅브라켓과 볼트 등의 체결수단을 매개로 차체에 체결된 스프링과 쇽업소버를 체결하는 차륜부위로 일단이 결합되어 차폭을 가로지르는 토션빔의 양측을 이루는 트레일링아암단부에 경사지게 형성된 부시설치부를 통해 횡 방향으로 차폭의 바깥쪽과 후방 차체쪽을 향하면서 소정 각도를 이루어 토션빔의 중심선상을 기준으로 하 방향 경사지도록 부시가 장착되되, The present invention for achieving the above object, one end is coupled to the wheel portion for fastening the shock absorber and the spring fastened to the vehicle body via a fastening means such as mounting brackets and bolts of the torsion beam across the width of the vehicle; The bush is mounted so as to be inclined downward with respect to the centerline of the torsion beam at a predetermined angle toward the outside of the vehicle width and the rear vehicle body in the transverse direction through the bush installation portion inclined to the trailing arm ends forming both sides,
상기 부시는 상기 트레일링아암의 부시설치부에 끼워져 압입·고정되는 부싱과, 이 부싱내에 끼워지면서 차폭의 바깥쪽 방향으로 돌출되는 스토퍼로 이루어진 것을 특징으로 한다. The bush is characterized by consisting of a bushing that is fitted into the bushing portion of the trailing arm and is press-fitted and fixed, and a stopper that is fitted into the bushing and protrudes outward of the vehicle width.
이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따라 선회안정성을 유지한 차량의 토션빔 타입 후륜 현가장치의 구성도이고, 도 2는 도 1을 K 방향에서 바라본 정면도를 도시한 것인바, 본 발명의 토션빔 타입 후륜 현가장치는 일단이 마운팅브라켓과 볼트 등의 체결수단을 매개로 차체에 체결된 스프링(S)과 쇽업소버(A)를 체결하는 차륜(W)부위로 일단이 결합되어 차폭을 가로지르는 토션빔(10)의 양측을 이루는 트레일링아암(11)단부에 경사지게 형성된 부시설치부(11a)를 통해 횡 방향으로 차폭의 바깥쪽과 후방 차체쪽을 향하면서 소정 각도(a,b)를 이루어 토션빔(10)의 중심선상을 기준으로 하 방향 경사지도록 부시(12)가 장착되되, 상기 부시(12)는 상기 트레일링아암(11)의 부시설치부(11a)에 끼워져 압입·고정되는 부싱(12a)과, 이 부싱(12a)내에 끼워지면서 차폭의 바깥쪽 방향으로 돌출되는 스토퍼(12b)로 이루어진다.1 is a configuration diagram of a torsion beam type rear wheel suspension of a vehicle maintaining the swing stability according to the present invention, Figure 2 is a front view viewed from the direction K in Figure 1, the torsion beam type rear wheel suspension of the present invention The device is a torsion beam (10), which has one end coupled to the wheel (W) portion for fastening the spring (S) fastened to the vehicle body and the shock absorber (A) by means of fastening means such as a mounting bracket and a bolt (10). The torsion beam 10 is formed at a predetermined angle (a, b) while facing toward the outer side of the vehicle width and the rear vehicle body in the transverse direction through the bush installation portion 11a formed to be inclined at the ends of the trailing arm 11 forming both sides of Bush 12 is mounted so as to be inclined downward based on the center line of the center, and the bush 12 is fitted with a bushing portion (11a) of the trailing arm (11) and the bushing (12a) is pressed and fixed Is inserted into the bushing 12a and protrudes in the outward direction of the vehicle width. Comprises a stopper (12b).
여기서, 상기 부시(12)는 도 3에 도시된 바와 같이 토션빔(10)의 중심선상을 기준으로 소정 각도(a',b')를 갖고 상 방향 경사지도록 설치되면서, 상기 부시(12)의 스토퍼(12b)가 차폭 안쪽을 향하도록 장착될 수 도 있음은 물론이다.Here, the bush 12 is installed to be inclined upward with a predetermined angle (a ', b') relative to the center line of the torsion beam 10, as shown in Figure 3, of the bush 12 Of course, the stopper 12b may be mounted to face the vehicle width inward.
이하 본 발명의 작동을 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the operation of the present invention will be described in detail with reference to the accompanying drawings.
본 발명에 따른 토션 빔 액슬 타입의 후륜 현가장치는 차량 선회 시 액슬 빔(1)이 비틀리고, 좌우 휠(11,11)이 각각 독립적으로 상향(up) 및 하향(dn) 이동하면서 독립 현가 역할을 하게 되고, 이 범프 및 리바운드 시 좌우휠(11,11)이 함께 상향(up) 및 하향(dn) 이동하여 리지드 액슬(rigid axle)처럼 작동하게 된다.In the torsion beam axle type rear wheel suspension according to the present invention, the axle beam 1 is twisted when the vehicle is turned, and the left and right wheels 11 and 11 independently move up and down, respectively. In the bump and rebound, the left and right wheels 11 and 11 move together up and down dn to act like a rigid axle.
또한, 본원은 차량이 선회(좌회전)할 때 도 4에 점선으로 표시된 바와 같이 차륜(W)이 토우-아웃(Toe-Out)으로 변화되는 것을 방지하게 되는데 즉, 도 2에 도시된 바와 같이 선회하는 내·외 차륜(W)의 접지점에서의 수직력(K")과 횡력(K')이 작용되면 토션빔(10)에 걸리는 하중은 트레일링암(11) 부시설치부(11a)위치에 가해지는 하중(Fy,Fz,Fy',Fz')과 스프링(S)에서의 하중(K'")들이 서로 평형을 이루게 되고, 이에 따라 트레일링암(11)에 걸리는 하중 방향은 트레일링암(11)의 수평면에 대하여 소정각(a,b)을 형성하면서 작용하게 된다.In addition, the present disclosure prevents the wheel W from changing to toe-out as indicated by the dotted line in FIG. 4 when the vehicle is turning (left turn), that is, turning as shown in FIG. 2. When the vertical force K "and the lateral force K 'at the ground point of the inner and outer wheels W are applied, the load applied to the torsion beam 10 is applied to the trailing arm 11 bush mounting portion 11a. The loads Fy, Fz, Fy ', Fz' and the loads K '"at the spring S are in equilibrium with each other, so that the load direction applied to the trailing arm 11 is determined by the trailing arm 11. It acts while forming predetermined angles a and b with respect to the horizontal plane.
이때, 상기 부시설치부(11a)위치에 가해지는 하중(Fy,Fz,Fy',Fz')에 의해 부시(12)에는 그 합력인 부시변형력(F,F')이 발생하게 되는데, 이와 같이 상기 부시변형력(F,F')이 트레일링암(11)에 대해 경사지게 작용하면 내륜(W)에 장착된 부시(12)에는 그 축(Axial)방향이 아닌 반경(Radial) 방향으로 외력이 작용하게 되고, 이는 상기 부시(12)의 축방향에 비해 상대적으로 하드(Hard)한 특성을 갖는 반경 방향 특성으로 인해 부시(12)의 변형이 매우 적게 된다.At this time, by the loads (Fy, Fz, Fy ', Fz') applied to the position of the bush installation portion 11a, the bush deformation force (F, F ') that is the force of the bush 12 is generated. When the bush deformation force (F, F ') is inclined with respect to the trailing arm 11, the external force is applied to the bush (12) mounted on the inner ring (W) in the radial direction, not its axial direction. This is because the deformation of the bush 12 is very small due to the radial characteristic which has a relatively hard characteristic compared to the axial direction of the bush 12.
이는, 상기 부시(12)의 스토퍼(12b)가 바깥쪽을 향하는 경우 선회시 내륜(W)부위의 트레일링암(10)이 하중의 대부분을 받기 때문에 외륜(W)에 작용하는 수평분력(Fy)보다 내륜(W)에 작용하는 수평분력(Fy')이 더 크게 작용하게 되고, 이에 따라 하중이 크게 작용되는 차륜(W)에서 부시(12)의 변형을 작게 하므로 도 4에 도시된 바와 같은 차륜(W)이 토우-아웃(Toe-Out)으로 변화되는 것을 방지하게 됨은 물론이다.This is because, when the stopper 12b of the bush 12 faces outward, the horizontal component Fy acting on the outer ring W because the trailing arm 10 of the inner ring W portion receives most of the load when turning. The horizontal component Fy 'acting on the inner ring W acts more, and thus, the deformation of the bush 12 is reduced in the wheel W on which the load is applied. Therefore, the wheel as shown in FIG. Of course, the (W) is prevented from changing to Toe-Out.
한편, 도 3에 도시된 바와 같이 부시(12)의 스토퍼(12b)가 차폭 안쪽을 향하도록 장착되는 경우에도 선회시 동일하게 차륜(W)이 토우-아웃(Toe-Out)으로 변화되는 것을 방지하게 되는데 즉, 도 3에 도시된 바와 같이 선회하는 내·외 차륜(W)의 접지점에서의 수직력(K")과 횡력(K')이 작용되면 토션빔(10)에 걸리는 하중은 트레일링암(11) 부시설치부(11a)위치에 가해지는 하중(Fy,Fz,Fy',Fz')과 스프링(S)에서의 하중(K'")들이 서로 평형을 이루게 되고, 이에 따라 트레일링암(11)의 수평면에 대하여 소정각(a',b')으로 위로 향하도록 장착된 부시(12)에는 작용하는 하중(Fy,Fz,Fy',Fz')에 의해 그 합력인 부시변형력(F,F')이 하 방향으로 발생하게 된다.Meanwhile, as shown in FIG. 3, even when the stopper 12b of the bush 12 is mounted to face inward of the vehicle width, the wheel W is prevented from being changed to toe-out during turning. That is, as shown in Figure 3 when the vertical force (K ") and the lateral force (K ') at the ground point of the inner and outer wheels (W) that rotates when the load applied to the torsion beam 10 is a trailing arm ( 11) The loads (Fy, Fz, Fy ', Fz') and the loads (K '") at the spring (S) applied to the position of the bush mounting portion 11a are in balance with each other, and thus the trailing arm 11 The bush 12 (F, F), which is its force due to the loads (Fy, Fz, Fy ', Fz') applied to the bush 12 mounted upward at a predetermined angle (a ', b') with respect to the horizontal plane of ') Is generated in the downward direction.
이때에도, 상기 부시(12)에 작용하는 부시변형력(F,F')이 그 축(Axial)방향이 아닌 반경(Radial) 방향으로 외력이 작용하게 되고, 이는 상기 부시(12)의 축방향에 비해 상대적으로 하드(Hard)한 특성을 갖는 반경 방향 특성으로 인해 부시(12)의 변형이 매우 적게 된다.At this time, the bush deformation force (F, F ') acting on the bush 12 is an external force acting in the radial direction, not its axial direction, which is in the axial direction of the bush 12 Compared with the relatively hard property, the radial property causes very little deformation of the bush 12.
이는, 상기 부시(12)의 스토퍼(12b)가 안쪽을 향하면서 위로 경사진 경우 선회시 외륜(W)부위의 트레일링암(10)이 하중의 대부분을 받기 때문에 내륜(W)에 작용하는 수평분력(Fy')보다 외륜(W)에 작용하는 수평분력(Fy)이 더 크게 작용하게 되고, 이에 따라 하중이 크게 작용되는 차륜(W)에서 부시(12)의 변형을 작게 하므로 도 4에 도시된 바와 같은 차륜(W)이 토우-아웃(Toe-Out)으로 변화되는 것을 방지하게 됨은 물론이다.This is because, when the stopper 12b of the bush 12 is inclined upward while facing inward, a horizontal component acting on the inner ring W because the trailing arm 10 of the outer ring W receives the most of the load during the turning. As shown in FIG. 4, the horizontal component Fy acting on the outer ring W is greater than the Fy ', thereby reducing the deformation of the bush 12 in the wheel W in which the load is large. Of course, the wheel W as described above is prevented from changing to Toe-Out.
이상 설명한 바와 같이 본 발명에 의하면, 트레일링암부위에 장착된 부시를 소정각도를 두고 경사지게 설치해 선회시 작용하는 횡력을 부시의 반경방향으로 작용되도록 하여 차륜을 토우-아웃으로 변화되지 않도록 하므로써 항상 주행 안정 성능을 최적으로 유지 할 수 있는 효과가 있게 된다.As described above, according to the present invention, the bush mounted on the trailing arm is inclined at a predetermined angle so that the lateral force acting during the turning acts in the radial direction of the bush so that the wheel does not change to toe-out at all times. The effect is to maintain optimal performance.
