Disclosed in the present invention is a braking device for preventing drag torque of a tractor. The drag braking device for a transmission of a tractor according to the present invention comprises a plate-shaped body (22) which is attached to one side of a mission case. A working oil inlet port (24) which is provided to guide introduced working oil along an oil passage is provided at one side of the body. A support cylinder is provided at the body, and the outer portion of the support cylinder is connected to the oil passage (26). A braking piston is installed at the inside of the support cylinder to be outwardly and elastically supported by means of the spring. The braking block is supported to be linked with the inside of the braking piston, and performs braking while coming in close contact with the outer surface of a rotating shaft by means of drag torque. The inner surface of the braking block is provided in an arc shape with a friction material attached to the inner surface. This arrangement increases safety.

    본 발명은 트랙터의 드래그 토크를 방지하는 제동장치를 제안한다. 본 발명의 트랙터의 트랜스미션용 드래그 제동장치는, 미션케이스의 일측에 부착되는 판상의 바디(22)를 포함하는데, 이러한 바디의 일측에는 유입되는 작동유를 오일통로를 따라 안내하기 위한 작동유 입구포트(24)를 구비하고 있다. 그리고 바디에는 지지실린더가 구비되는데, 이러한 지지실린더의 외측부분은 오일통로(26)와 연결된다. 이러한 지지실린더의 내부에는 스프링에 의하여 외측으로 탄성적으로 지지되는 제동피스톤이 설치되어 있다. 그리고 제동블럭은, 제동피스톤의 내측과 연동하도록 지지되고, 드래그 토크에 의하여 회전하는 축의 외측면에 밀착되어 제동시키게 된다. 여기서 제동블럭의 내측면은 원호형으로 이루어지고, 제동블럭의 내측면에는 마찰재를 부착하는 것이 바람직하다.
