The present invention provides a differential locking device for a tractor. The differential locking device for a tractor comprises: an axel housing; a differential device installed in the axel housing; and a pair of output shafts (52) connected to a left and a right side of the differential device. The differential locking device for a tractor further comprises: a clutch unit (44C) formed on an outer end of a first differential casing of the differential device; a clutch member (80) having a clutch unit (82) to be mounted on the clutch unit (44C), wherein a middle portion thereof is spline-mounted on a first output shaft to be moved in an axial direction on the outside of the first differential casing; and a drive means installed in the axel housing to mount the clutch unit (82) of the clutch member (80) on the clutch unit (44C) of the first differential casing or separate the clutch unit (82) of the clutch member (80) from the clutch unit (44C) of the first differential casing. The drive means consists of a hydraulic cylinder and moves a linking fork connected to the clutch member back and forth.

    본 발명은 트랙터의 차동 잠금장치를 제안하고 있다. 본 발명은 액슬하우징과, 상기 액슬하우징 내부에 설치되는 차동장치, 상기 차동장치의 좌우측으로 연결되는 한 쌍의 출력축(52)을 구비하는 트랙터의 차동 잠금장치이고, 상기 차동장치의 제1차동케이싱의 외측단부에 성형되는 클러치부(44C); 상기 제1차동케이싱의 외측에서, 중심부분이 제1출력축에 스플라인 결합되어 축방향으로 이동 가능하고, 상기 클러치부(44C)에 결합될 수 있는 클러치부(82)를 구비하는 클러치부재(80); 그리고 상기 액슬하우징에 설치되어, 상기 클러치부재(80)의 클러치부(82)가 제1차동케이싱의 클러치부(44C)에 결합시키거나 이격시키는 구동수단으로 구성된다. 여기서 구동수단은 유압실린더로 구성되고, 클러치부재와 연결되는 연동포크를 왕복운동시킨다.
