Abstract

본 발명은 하부 현가암의 길이를 변화시킬 수 있는 독립식 현가장치에 관한 것으로, 본 발명에 의한 현가장치는 전기제어 유닛으로부터 전달된 전기신호에 의해 유압이 작용함에 따라 유압 실린더의 내부에 설치된 피스톤이 길이방향으로 미끄럼 운동하며, 이때 볼 조인트를 통해 유압 실린더와 연결된 조향 너클과 타단에 연결된 하부 현가암간의 길이를 변화시켜 차량의 하중이나 선회각도에 따라 캠버각 및 트레드의 관계를 적절히 유지시켜 선회능력을 증대시키고 타이어의 이상 마모를 크게 줄일 수 있다.The present invention relates to an independent suspension that can change the length of the lower suspension arm, the suspension according to the present invention is a piston installed inside the hydraulic cylinder as the hydraulic pressure acts by the electric signal transmitted from the electric control unit In this longitudinal direction, the length of the steering knuckle connected to the hydraulic cylinder through the ball joint and the lower suspension arm connected to the other end is changed to maintain the relationship between the camber angle and the tread according to the load or the turning angle of the vehicle. It can increase the capacity and greatly reduce the abnormal wear of the tire.
