Abstract

자동변속기 차량에서 유체 클러치용 유체는 일정한 점성을 가지므로 전기적으로 유체의 점성을 제어하여 차속이 감속되면서 브레이크를 밝을 경우 점차적으로 유체의 점성을 강하시켜 입력축과 출력축간의 마찰이 생기지 않도록 하여 에너지를 절약하도록 하는 유체 클러치의 전기 점성 유체 가변 장치가 개시된다.In the automatic transmission vehicle, the fluid clutch fluid has a certain viscosity, so the viscosity of the fluid is controlled electrically, so when the brake speed is reduced and the brake is bright, the fluid viscosity gradually drops to prevent friction between the input and output shafts, thus saving energy. An electrically viscous fluid variable device of a fluid clutch is disclosed.

자동차의 차속을 측정하는 차속센서수단과, 자동차의 기어의 위치를 측정하는 기어 포지션수단과, 브레이크의 상태를 감지하여 브레이크를 제어하는 브레이크 이시유 수단과, 차속의 정보 및 자동차의 기어 위치에 대한 정보를 입력받아 유체 클러치에 입력되는 전압을 변화시키는 이시유 수단과, 이시유 수단으로부터 출력되는 전압을 입력받아 유체의 점성을 변화시켜 유체 클러치를 제어하는 유체 점성 제어수단을 포함한다. 이에 따라, 에너지소비를 감소시킬 수 있는 유체 클러치의 전기 점성 유체 가변 장치를 간단하고도 용이하게 실현시킬 수 있다는 효과가 있다.The vehicle speed sensor means for measuring the vehicle speed of the vehicle, the gear position means for measuring the position of the gear of the vehicle, the brake transfer means for detecting the brake state and controlling the brake, the information of the vehicle speed and the gear position of the vehicle And a liquid oil viscosity control means for controlling the fluid clutch by receiving the information and changing the voltage input to the fluid clutch and the voltage output from the liquid oil means to change the viscosity of the fluid. Accordingly, there is an effect that the electric viscous fluid variable device of the fluid clutch which can reduce energy consumption can be realized simply and easily.
