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) spline-mounted on a first output shaft from the outside of the first differential casing, and provided with a clutch unit (82) to be mounted on the clutch unit (44C); a switching fork (70) which is rotatably supported on the axel housing by a support shaft (72), and applies a force to move the clutch member in an axial direction by rotation to one side to mount the clutch unit (82) on the clutch unit (44C) of the first differential casing; a drive means which applies a force to rotate the switching fork in a direction in which the clutch member is mounted on the first differential casing, and is installed in the axel housing; and a spring inserted into the first output shaft between the clutch member and a first side gear (44L) of the differential device to provide an elastic force in a direction in which the clutch member is separated from the first differential casing.

    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, 제1출력축에 스플라인 결합되고, 상기 클러치부(44C)에 결합될 수 있는 클러치부(82)를 구비하는 클러치부재(80); 상기 액슬하우징에 지지축(72)을 통하여 회동 가능하게 지지되고, 일측으로의 회동에 의하여 클러치부재를 축방향으로 이동시켜 그 클러치부(82)가 제1차동케이싱의 클러치부(44C)와 결합되도록 힘을 가하는 절환포크(70); 상기 클러치부재가 제1차동케이싱과 결합되는 방향으로 상기 절환포크를 회동시키는 힘을 가할 수 있고, 상기 액슬하우징에 설치된 구동수단; 그리고 상기 클러치부재와 차동장치의 제1사이드기어(44L) 사이에서 제1출력축에 삽입되어, 클러치부재를 제1차동케이싱에서 분리되는 방향으로 탄성력을 발휘하는 스프링으로 구성된다.
