본 발명은 차량의 리어서스펜션으로 많이 사용되는 토션빔액슬에 관한 것으로서, 보다 상세하게는 토션빔액슬이 채용된 차량에 횡력이 작용할 때 토션빔액슬 자체의 특성상 발생되는 오버스티어 현상을 능동적으로 배제시킬 수 있도록 하는 장치에 관한 것이다.The present invention relates to a torsion beam axle that is frequently used as a suspension of a vehicle. More particularly, the present invention relates to a torsion beam axle that actively eliminates an oversteer phenomenon caused by the characteristics of the torsion beam axle itself when a lateral force is applied to a vehicle employing the torsion beam axle. It relates to a device that allows.

토션빔액슬은 차체의 길이방향을 따라 배치되는 좌/우측 트레일링암과, 이 좌/우측 트레일링암 사이를 연결하도록 차체의 횡방향을 따라 배치되는 토션빔을 구비하고, 상기 토션빔의 양측 후방에 휠과 스프링 및 쇽업소버가 연결되도록 되어 있다.The torsion beam axle includes a left / right trailing arm disposed along the longitudinal direction of the vehicle body, and a torsion beam disposed along the transverse direction of the vehicle body so as to connect between the left and right trailing arms, and on both rear sides of the torsion beam. The wheel, spring and shock absorber are connected.

상기한 바와 같은 토션빔액슬의 전방은 통상 차체에 마운팅부시에 의해 결합되는데, 이와 같은 토션빔액슬이 채용된 차량은 도 1에 도시된 바와 같이 차량의 횡방향으로 작용하는 횡력에 대하여 상기 마운팅부시가 변형되면서 토션빔액슬(500) 자체의 움직임이 발생하게 된다.The front of the torsion beam axle as described above is normally coupled to the vehicle body by a mounting bush. The vehicle employing such a torsion beam axle is mounted on the lateral force acting in the lateral direction of the vehicle as shown in FIG. As the deformation of the torsion beam axle 500 itself occurs.

특히, 상기한 바와 같이 차량에 횡력이 작용하는 경우는 대체로 차량이 선회중인 경우로서, 도 1에서와 같이 차량이 좌측으로 선회하는 경우에 리어휠에 작용하는 횡력은 도시된 바와 같이 토션빔액슬(500)이 움직이도록 하는데, 이러한 토션빔액슬(500)의 움직임은 언더스티어를 발생시키는 상태이므로 차량의 조종안정성이 저해되는 문제점이 있다.In particular, when the lateral force is applied to the vehicle as described above, the vehicle is generally turning. As shown in FIG. 1, the lateral force acting on the rear wheel is torsion beam axle (as shown). In order to move the 500, such a torsion beam axle 500 has a problem in that the steering stability of the vehicle is impaired because the understeer is generated.

종래에, 상기한 바와 같은 문제점에 대응하기 위해 토션빔액슬(500)과 차체 사이를 연결하는 마운팅부시의 구조 및 특성 등을 조정하는 방법이 제시되고 있으나, 그 효과가 미미한 실정이다.Conventionally, in order to cope with the above problems, a method of adjusting the structure and characteristics of the mounting bush connecting the torsion beam axle 500 and the vehicle body has been proposed, but the effect thereof is insignificant.

본 발명은 토션빔액슬이 채용된 차량에서 선회시에 작용하는 횡력에 대하여 오버스티어가 발생되는 토션빔액슬의 거동을 방지함은 물론, 적극적으로 토션빔액 슬의 언더스티어를 유도할 수 있도록 하여 차량의 조종안정성을 크게 향상시킬 수 있도록 한 토션빔액슬의 토우각 조절장치를 제공함에 그 목적이 있다.The present invention not only prevents the torsion beam axle from generating oversteer with respect to the lateral force acting upon turning in a vehicle employing the torsion beam axle, but also actively induces the understeer of the torsion beam axle. The purpose of the present invention is to provide a toe angle control device of the torsion beam axle, which can greatly improve the steering stability of the vehicle.

를 포함하여 구성된 것을 특징으로 한다.Characterized in that configured to include.

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 2를 참조하면, 본 발명 실시예는 토션빔액슬(1)의 차체 마운팅부로부터 차량의 전방으로 연장되어 일체로 형성된 연장부(3)와; 상기 연장부(3)에 연결되어 상기 연장부(3)를 차체의 횡방향으로 회동시킬 수 있도록 설치된 액츄에이터(5)와; 차량의 주행상태를 감지 및 판단하여 상기 액츄에이터(5)를 제어하는 컨트롤러(7)를 포함하여 구성된다.2, an embodiment of the present invention includes an extension part 3 formed integrally extending from the vehicle body mounting part of the torsion beam axle 1 in front of the vehicle; An actuator (5) connected to the extension part (3) and installed to rotate the extension part (3) in the transverse direction of the vehicle body; And a controller 7 for controlling the actuator 5 by sensing and determining a driving state of the vehicle.

물론, 상기 토션빔액슬(1)의 차체 마운팅부는 토션빔액슬(1)의 토션빔을 기 준으로 차체 전방측으로 길게 형성된 종래의 트레일링암에 해당하는 부위에 형성되며, 상기 마운팅부에는 종래와 마찬가지로 차체와 토션빔액슬(1) 사이의 차량 횡방향의 각도변화를 수용할 수 있도록 고무재질의 마운팅부시(13)에 의해 연결된다.Of course, the vehicle body mounting portion of the torsion beam axle 1 is formed at a portion corresponding to a conventional trailing arm formed long to the front side of the vehicle body based on the torsion beam of the torsion beam axle 1, and the mounting portion is similar to the conventional one. It is connected by a mounting bush 13 made of rubber material so as to accommodate the change in the lateral direction of the vehicle between the vehicle body and the torsion beam axle 1.

상기 액츄에이터(5)는 작동로드(9)가 직선 운동하며, 상기 작동로드(9)의 이동된 상태는 피동측으로부터 역구동되지 않는 직선운동 액츄에이터를 채용하여, 액츄에이터(5)에 의해 설정된 휠의 토우각이 일정하게 유지될 수 있도록 하였으며, 상기 직선운동 액츄에이터의 작동로드(9)는 연결로드(11)를 통하여 상기 연장부(3)에 연결되는 구조를 취하였다.The actuator 5 has a linear movement of the actuating rod 9, and the moving state of the actuating rod 9 employs a linear movement actuator which is not driven back from the driven side, so that the wheel of the wheel set by the actuator 5 The toe angle was kept constant, and the actuating rod 9 of the linear motion actuator took a structure connected to the extension part 3 through the connecting rod 11.

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 주행중에 선회가 발생되면, 상기 컨트롤러(7)는 이를 감지 및 판단하여, 상기 액츄에이터(5)를 제어한다. When turning is generated while the vehicle is running, the controller 7 detects and determines this and controls the actuator 5.

상기 액츄에이터(5)의 작동로드(9)가 직선운동하면, 그 운동은 상기 연결로드(11)를 통하여 상기 연장부(3)로 전달된다.If the actuating rod 9 of the actuator 5 moves linearly, the movement is transmitted to the extension part 3 via the connecting rod 11.

상기 연장부(3)는 상기 연결로드(11)로부터 제공된 힘에 의해 회동됨으로써 도 2의 점선과 같이 차량의 횡방향으로 토션빔액슬(1)이 회동될 수 있도록 한다.The extension part 3 is rotated by the force provided from the connecting rod 11 so that the torsion beam axle 1 can be rotated in the transverse direction of the vehicle as shown by the dotted line of FIG. 2.

물론 이때 상기 토션빔액슬(1)의 회동중심은 대체로 상기 마운팅부시(13)에 형성되며, 이와 같은 토션빔액슬(1)의 회동상태는 상기 마운팅부시(13)의 탄성변형의 범위 내에 속하도록 제어가 이루어져야 한다.Of course, the pivot center of the torsion beam axle 1 is generally formed in the mounting bush 13, and the rotational state of the torsion beam axle 1 falls within the range of elastic deformation of the mounting bush 13. Control must be made.

따라서, 상기한 바와 같은 토션빔액슬(1)의 토우각 조절장치를 구비한 차량 은 차량의 선회 주행중에 종래와 같이 피할 수 없는 오버스티어 경향을 배제할 수 있음은 물론, 상기 액츄에이터(5)의 작동 정도에 따라 언더스티어도 형성할 수 있어서, 차량의 조종안정성을 크게 향상시킬 수 있다.Therefore, the vehicle provided with the toe angle adjusting device of the torsion beam axle 1 as described above can not only eliminate the inevitable oversteer tendency as in the related art during turning of the vehicle, but also of the actuator 5. Understeer can also be formed depending on the degree of operation, which greatly improves the steering stability of the vehicle.

이상과 같이 본 발명에 의하면, 토션빔액슬이 채용된 차량에서 선회시에 작용하는 횡력에 대하여 오버스티어가 발생되는 토션빔액슬의 거동을 방지함은 물론, 적극적 및 능동적으로 토션빔액슬의 언더스티어를 유도할 수 있도록 하여 차량의 조종안정성을 크게 향상시킬 수 있도록 한다.As described above, according to the present invention, it is possible to prevent the oversteer axle from generating oversteer with respect to the lateral force acting upon turning in a vehicle employing the torsion beam axle, and to actively and actively understeer the torsion beam axle. It is possible to greatly improve the steering stability of the vehicle by inducing.
