The present invention relates to a working vehicle having a vibration reduction suspension apparatus. According to the present invention, the working vehicle having a vibration reduction suspension apparatus comprises: a main frame formed to make a lower framework; a wheel unit with four wheels, which is coupled to a front surface and a rear surface of the main frame and includes two front wheels and two rear wheels; and a main body frame which is provided on an upper side of the main frame and provides a space on an upper surface for placing the driver′s seat, the driving lever, and the control apparatus. On a front surface of the main frame, placed is a pair of caster frames extending towards the front wheels and coupled to each other to be spaced apart for a certain distance. The end units of the caster frames are coupled to each other on the main frame to be rotatable vertically. Between the caster frames, placed is an elastic body which connects the end units of the caster frames to each other. The working vehicle is able to drive with the front wheels following the ground surface.

    본 발명에 따른 진동저감 현가장치가 구비된 작업차량은 하부 골격을 이루도록 형성된 메인 프레임과, 상기 메인 프레임의 전면과 후면에 결합되며 2개의 전륜과 후륜으로 이루어진 4륜 형식의 바퀴부 및 상기 메인 프레임의 상부에 마련되어 상면에 운전석과 운전레버 및 제어장치가 배치되는 공간을 제공하는 본체 프레임으로 이루어지며, 상기 메인 프레임의 전면에는 전륜 방향으로 연장형성되며 소정거리 이격되도록 결합된 한쌍의 캐스터 프레임이 배치되고, 상기 캐스터 프레임의 단부는 상기 메인 프레임 상에서 상하방향으로 회전가능하도록 결합되며, 상기 캐스터 프레임의 사이에는 상기 캐스터 프레임의 단부를 서로 연결하는 탄성체가 구비되는 구조로, 작업차량의 전륜이 지면을 추종하면서 운행이 가능하다.
