Abstract

각종 제어 장치를 차량에 탑재할 때의 공간적인 문제, 중량 문제 및 차량의 생산성을 개선한다.
전동모터(110)의 회전축(111)에 제1 및 제2펌프(120,130)을 접속한다. 전동모터(110)의 작동에 의해 제1펌프(120)는 차고조정용 유체식 제어장치에 압축공기를 토출하는 동시에 제2펌프(120)는 앤티록 브레이크(또는 점착마찰, 안정성 제어)용 유체식 제어장치에 작동유를 토출한다. 차고조정용 유체식 제어장치는 차량의 발진전까지의 정지중에 작동되는 수가 많고 앤티록 브레이크(또는 점작마찰, 안정성 제어)용 유체식 제어 장치는 차량의 발진시 또는 주행중에 작동하는 일이 많고 양 유체식 제어 장치는 동시에 작동하는 일이 거의 없으므로 양 유체식 제어 장치의 기능을 다치는 일이 없이 전동모터(110)을 유효하게 활용할 수 있다.
