Abstract

본 발명은 배터리식 포크리프트 등의 유압 파워 스티어링 장치의 파워 스티어링 모터(1)를 제어하기 위한 장치(7)에 관하고, 그 목적으로 하는 것은 정차시의 모터 구동 시간을 가능한 단축하는데 있다. 본 발명의 제어 장치는 모터(1)에 접속된 콘택터(3)를 디렉션 스위치(5)가 중립에 있는지 아닌지에 의하여 개폐 제어하는 형식의 것이고, 이 장치에 차속 센서(13)를 접속하고, 이 차속 센서(13)에서 차속 정보를 취입하여 주행 상태인지 정차 상태인지를 판단하고, 주행 상태에 있는 경우에는 모처(1)를 구동하고, 일정 시간 이상 정차 상태에 있는 경우에는 모터(1)를 정지하도록 한 것을 특징으로 한다.The present invention relates to a device (7) for controlling the power steering motor (1) of a hydraulic power steering device such as a battery type forklift, and its object is to reduce the motor driving time at the time of stopping as much as possible. The control device of the present invention is of a type in which the contactor 3 connected to the motor 1 is opened / closed and controlled by the direction switch 5 being neutral or not, and the vehicle speed sensor 13 is connected to the device. The vehicle speed sensor 13 takes in the vehicle speed information to determine whether the vehicle is in a driving state or a stationary state. When the vehicle is in the driving state, the motor 1 is driven. When the vehicle is in the stopped state for a predetermined time or more, the motor 1 is stopped. It is characterized by that.
