Description

차량용 광역 진동 저감 서스펜션{VEHICLE SUSPENSION CAPABLE OF REDUCING VIBRATION IN WIDE RANGE}[0001] VEHICLE SUSPENSION CAPABLE OF REDUCING VIBRATION IN WIDE RANGE [0002]

본 발명은 차량용 광역 진동 저감 서스펜션에 관한 것이다.The present invention relates to a wide area vibration reduction suspension for a vehicle.

한국공개실용신안(2000-0019209)에 도시된 바와 같이,As shown in Korean Utility Model Application (2000-0019209)

종래 차량용 서스펜션은 암이 행거에 볼트로 고정되는 구조를 가진다.Conventional vehicle suspensions have a structure in which the arms are fixed to the hanger with bolts.

행거는 차체와 연결된다.The hanger is connected to the vehicle body.

에어백은 암과 차체 사이에 설치된다.The airbag is installed between the arm and the vehicle body.

암은 에어백을 지지하며, 차체의 하중을 차축에 전달한다.The arm supports the airbag and transfers the load of the vehicle body to the axle.

차축은 암에 설치된다.The axle is mounted on the arm.

차량 운행시 노면과 차량에서 발생하는 진동은, 암과 행거를 거쳐 차체로 그대로 전달된다.The vibration generated from the road surface and the vehicle is transmitted to the vehicle body through the arm and the hanger when the vehicle is running.

에어백은 차체로 전달되는 큰 진동을 어느 정도 감소시킨다.The air bag reduces the large vibration transmitted to the vehicle body to some extent.

그러나, 에어백은 승차감에 영향을 미치는 중(中) 진동과 소(小) 진동은 거의 잡아주지 못한다.However, the airbag hardly catches medium vibration and small vibration which affect ride quality.

이로 인한, 소비자 불만이 계속 이어지고 있다.As a result, consumer complaints are continuing.
