Description

전동식 후륜 조타장치
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 본 발명의 일실시예에 따른 전동식 후륜 조타장치의 구성도, 제2도는 그 회전식 후륜 조타장치의 요부를 도시한 블럭구성도이다.

Claims (2)

  1. 전륜조타 상태에 따른 후륜을 모터로 조타 구동하는 전동식 후륜 조타장치에 있어서, 핸들의 조타방향, 조타각, 조타토오크, 조타속도 등 중 적어도 하나의 조타상태를 검출하는 핸들 조타상태 센서, 차속을 검출하는 코토회전 속도센서 및 후륜의 조타각도를 검출하는 후륜 조타각 센서, 상기ㄴ 모터와 그 모터의 회전력을 전달하는 역전효율 0이하의 위엄감속기 사이에 삽입 설치되고, 상기 모터의 회전력을 결합, 이탈시키는 전자클러치, 상기 워엄감속기의 출력에 의해 구동되고, 상기 후륜을 조타시키는 후륜 조타용 기어박스, 상기 각센서의 신호를 입력하고 이들 각 센서의 신호를 기초로 한 상기 모터를 구동 제어하는 동시에, 소정 동작 이외의 이상이라고 판단한 경우 상기 모터의 통전을 차단하고 상기 전자 클러치를 이탈상태로 시키는 제어유니트를 구비한 것을 특징으로 하는 전동식 후륜 조타장치.
  2. 제1항에 있어서, 모터 및 전자클러치에의 전원공급 라인도중에 배치된 상개 접점을 갖는 비상안전 릴레이와, 이 비상안전 릴레이를 구동시키는 비상안전 릴레이 구동회로를 구비하고, 제어유니트가 각 센서신호에 의해 장치의 이상이라고 판단한 경우, 각 제어유니트는 상기 비상안전 릴레이 구동회로에 대해 비상안전릴레이의 차단신호를 송출하는 것을 특징으로 하는 전동식 후륜 조타장치.
    ※참고사항 : 최초출원 내용에 의하여 공개하는 것임.
