Abstract

본 고안은 자동차의 더블위시본형 현가장치의 너클 연결구조에 관한 것으로서, 기존의 현가장치는 자동차의 상하 방향으로만 유연하여 상하 충격만을 억제하는 한계가 있었기 때문에, 이를 보완하기 위해 본 고안을 적용하면 바퀴가 상하뿐만 아니라, 동시에 전후 방향으로도 운동할 수 있게 하여 유연성이 증대되어 승차감이 향상된다. 상기 고안은 기존의 현가장치의 어퍼암(1)에 좌우로 회전가능하게 연결된 너클(2)을 추가로 전후 방향으로 회전 가능하게 연결하고, 너클(2)에 로워암(3)의 회전부에 전후로 이동이 가능한 레일(4)을 추가로 만들어 상하 방향 및 전후 방향으로 유연성을 제공하여 승차감을 향상시킨다.The present invention relates to a knuckle connection structure of a double wishbone suspension of a vehicle, and the existing suspension has a limitation of suppressing only an up and down impact by being flexible only in the up and down direction of a vehicle. The wheels can be moved not only up and down, but also in the front and rear directions at the same time, thereby increasing flexibility and improving riding comfort. The above invention further connects the knuckle (2) rotatably connected to the upper arm (1) of the existing suspension device in a forward and backward direction, and is connected to the knuckle (2) to the rotating part of the lower arm (3). The movable rail 4 is further provided to provide flexibility in the vertical direction and the front and rear directions, thereby improving the riding comfort.

Description

더블 위시본형 완충장치{ double wishbone suspention }Double wishbone suspention

본 고안은 더블위시본형 현가장치의 너클 연결구조에 관한 것으로서, 보다 자세하게는 기존의 현가장치의 상하 방향의 충격억제 작용뿐만 아니라, 전후 방향의 충격억제도 가능하게 하는 고안이다. 일반적인 현가장치의 중요한 기능은 자동차의 상하 방향으로 유연성을 제공하여 노면의 요철로 인한 충격이나 진동을 완화하여 차체에 전달되지 않도록 하는 것이다. 기존의 현가장치는 바퀴를 상하 방향으로만 움직이며 충격을 완화했다. 하지만 자동차가 주행 시 노면의 요철에 의해 바퀴가 받는 충격방향은 차속이 빠르면 빠를수록 상하 방향이 아닌, 전후 방향의 충격에 가까워진다. 따라서 상하 방향으로만 유연한 기존의 현가장치들은 고속 주행 시 노면의 요철에 의한 충격을 효과적으로 완화하지 못하는 문제점이 있다.The present invention relates to a knuckle connection structure of a double wishbone suspension system, and more particularly, to devise a shock suppression effect in the front and rear directions as well as the impact suppression in the vertical direction of the existing suspension system. An important function of the general suspension system is to provide flexibility in the vertical direction of the vehicle so as to alleviate the shock or vibration caused by the unevenness of the road surface, so that it is not transmitted to the vehicle body. The existing suspension system has only dampened the impact by moving the wheels only up and down. However, when the vehicle is driving, the impact direction of the wheels due to the unevenness of the road becomes faster as the vehicle speed gets faster and closer to the impact of the front and rear directions, not the vertical direction. Therefore, the existing suspension devices that are flexible only in the vertical direction have a problem in that the high-speed driving does not effectively alleviate the impact caused by unevenness of the road surface.

이에 본 고안은 상기한 문제점을 보완하고자 자동차의 상하전후 방향에 유연한 현가장치를 만들어 승차감 증대를 목적으로 한다.In this regard, the present invention aims to increase ride comfort by making a flexible suspension device in up and down directions of a vehicle to compensate for the above problems.

첨부되는 도면과 관련하여 본 고안의 구성과 작용에 대하여 설명하면 다음과 같다. 더블위시본형 현가장치에서 어퍼암(1)과 너클(2)을 좌우로 회전 가능하게 볼조인트로 연결하고, 추가로 너클(2)이 전후로 회전 가능하게 볼조인트로 연결한다. 너클(2)에 전후로 이동이 가능한 레일(4)을 만들고, 로워암(3)과 너클(2)의 좌우로 회전가능하게 연결된 회전부와 레일(4)을 연결한다. 레일 내에는 전후 방향의 운동을 억제할 수 있는 완충장치를 삽입한다. 주행 시 너클(2)에 충격이 전해지면 상하의 충격은 기존의 현가장치가 흡수하고, 전후 방향의 충격은 전후 방향으로 회전가능하게 추가로 만든 연결부를 축으로 한 레일(4)의 전후 운동으로 변하고, 이 운동을 레일내의 완충장치가 흡수한다. 이에 충격의 방향에 따라 충격을 분산해 완화하기 때문에 효과적으로 충격을 억제할 수 있다.Referring to the configuration and operation of the present invention with reference to the accompanying drawings as follows. In the double wishbone suspension system, the upper arm 1 and the knuckle 2 are connected to the ball joint so as to rotate left and right, and the knuckle 2 is connected to the ball joint so as to rotate back and forth. A rail 4 which is movable back and forth on the knuckle 2 is made, and the rotary part and the rail 4 which are rotatably connected to the left and right of the lower arm 3 and the knuckle 2 are connected. The shock absorber which can suppress the movement of the front-back direction is inserted in the rail. When the shock is transmitted to the knuckle 2 during driving, the upper and lower shocks are absorbed by the existing suspension device, and the front and rear shocks are changed by the forward and backward motion of the rail 4 around the connecting part made to be rotatable in the front and rear directions. This movement is absorbed by the shock absorber in the rail. Accordingly, since the shock is dispersed and mitigated along the direction of the shock, the shock can be effectively suppressed.

이상과 같이 본 고안은 전후 방향의 충격을 완화할 수 있는 구조를 기존의 현가장치에 적용하여 동시에 자동차의 상하전후 방향으로 바퀴의 운동을 완화시켜 유연성이 기존의 현가장치보다 증대되어 승차감이 향상된다.As described above, the present invention adopts a structure that can alleviate the impact of the front and rear direction to the existing suspension device, and at the same time, the wheel movement in the vertical direction of the car is alleviated, thereby increasing the flexibility and the ride comfort. .
