Abstract
본 발명의 목적은 자동 변속 차량의 브레이크 실패시 자동적으로 저단 변속되어 엔진 브레이크가 이루어지도록 하는 3속 자동 변속기의 엔진 브레이크 유압 제어 시스템을 제공하는데 있다.SUMMARY OF THE INVENTION An object of the present invention is to provide an engine brake hydraulic control system of a three speed automatic transmission in which a low speed is automatically shifted to achieve an engine brake when a brake fails in an automatic transmission vehicle.
이를 실현하기 위한 본 발명은 3속 자동 변속기의 탑재한 차량에서 3속 주행시 제동의 실패를 방지하기 위해 2,3속 변속이 이루어지도록 하는 시프트 밸브에 연결되어 거버너 벨브를 통한 유압이 제7포트로 유입되는 제3관로와, 이 제3관로를 통해 유입되는 유압의 가감에 따라 스로틀 밸브의 개구정도에 따른 모듈레이터 압력이 제10포트에 유입되도록 한 제7관로와, 상기 제3관로와 제7관로를 직접 연결한 제8관로를 연통하는 솔레노이드 밸브와, 이 솔레노이드 밸브를 제동 실패시 개구되도록 제어하여 2속 변속이 이루어지도록 하는 전자제어장치와, 이 전자제어장치에 의해 제동 실패시 전원이 인가되도록 운전자가 온(ON)작동시키는 작동 스위치를 포함하여 이루어지는 3속 자동 변속기의 엔진 브레이크 유압 제어 시스템을 특징으로 한다.The present invention for realizing this is connected to a shift valve to achieve a 2, 3 speed shift in order to prevent braking failure during 3 speed driving in a vehicle equipped with a 3 speed automatic transmission, so that the hydraulic pressure through the governor valve is transferred to the 7th port. A third pipe which flows in and a modulator pressure according to the opening degree of the throttle valve according to the opening and closing of the throttle valve according to the flow of the third pipe and the third pipe and the seventh pipe A solenoid valve communicating with an eighth conduit connected directly to the engine, an electronic controller which controls the solenoid valve to open when braking fails, so that a two-speed shift is made, and when the braking failure is applied by the electronic controller, It features an engine brake hydraulic control system of a three-speed automatic transmission that includes an actuating switch that the driver turns ON.
