Abstract
Description
Claims (1)
- 무단 변속기를 채용한 트랙터에 있어서, 마그네틱 픽업(23)을 이용하여 엔진 회전수의 변동만을 측정하여 엔진에 인가되는 부하가 없는 불감대 영역인 a 구간에서의 증폭비는 '0'이므로 적은 양의 속도차 신호에 대해서는 트랙터의 속도를 변화시키지 않고, 감속 영역인 b 구간에서는 부하 토크의 양에 비례하는 신호를 신호 통합부(21)로 출력하여 트랙터의 속도를 감속시키며, 급감속 영역인 c 구간에서는 부하토크가 엔진을 짧은 시간 내에 정지시킬 만큼 큰 값임을 나타내고 있으므로 증폭비를 크게하여 트랙터를 급감속시킬 수 있도록 하는 것을 특징으로 하는 무단변속 트랙터의 작업부하 제어방법.
