Disclosed is a front axle suspension of a work vehicle which supports the front weight of a work vehicle and absorbs/alleviates an impact in accordance with vertical vibration of front wheels to prevent the impact from being transferred to the chassis to provide improved riding comfort. According to the present invention, the front axle suspension comprises: an axle support part to which a differential motion case of a front axle unit is coupled to be laterally shaken; a pair of suspension cylinders installed between a front chassis frame and the axle support part; a housing part which is connected to the axle support part and accommodates an input shaft for transferring driving power to front wheels; and a lateral shaking restriction part installed on the upper end of the axle support part. One end of the housing part is integrally connected to the axle support part and the other end of the housing part is pivot-connected to a lower portion of one side of a transmission case to be vertically shaken. The lateral shaking of the front axle unit with respect to the front chassis frame is limited to a prescribed angle by the lateral shaking restriction part.

    작업차의 전방 하중을 지지함과 동시에 전방 차륜의 상하 진동에 따른 충격이 차체에 전달되지 않도록 흡수/완화함으로써 향상된 승차감을 제공하는 작업차의 프런트 액슬 서스펜션이 개시된다. 본 발명에 따른 프런트 액슬 서스펜션은, 전방 차축 유닛의 차동 케이스가 횡방향으로 요동 가능하게 결합되는 차축 지지부와, 전방 차체 프레임과 상기 차축 지지부 사이에 설치되는 한 쌍의 서스펜션 실린더와, 차축 지지부에 연결되고 전방 차륜에 구동력을 전달하는 입력축을 수용하는 하우징부 및 차축 지지부의 상단에 설치되는 횡요동 규제부를 포함하며, 하우징부는 일단이 차축 지지부에 일체로 연결되고 타단이 미션케이스의 일측 저부에 상하 방향으로 요동 가능하게 피봇 연결되며, 횡요동 규제부에 의해 상기 전방 차체 프레임에 대한 전방 차축 유닛의 횡방향 요동을 일정 각도로 제한되는 것을 특징으로 한다.
