Abstract

The invention discloses an improved invention of a silicon oil fan clutch, which is essentially characterized in that a control component is composed of an executing unit, a temperature sensor and an ECU. The executing component and the temperature sensor are respectively connected with the ECU. In the invention, as a previous thermal sensitive spiral and bimetal spring temperature detector is modified into an electronic temperature sensor for detecting the temperature, and then the detected temperature is fed back to the ECU (an electronic controller unit) which rapidly sends out an order to cause the executing unit to be operated after distinguishing treatment, an oil inlet is opened and closed rapidly and precisely by a valve. Compared with the prior art, the invention has outstanding substantive features and obvious progress.

Description

Technical field: [0001] The invention relates to an improved invention for controlling a silicon oil fan clutch mechanism on an automobile cooling system, and specifically relates to an invention for electronically controlling a silicon oil fan clutch. Background technique: [0002] In the prior art, the fan is the consumer of engine power, and the maximum time is about 10% of the engine power. In order to reduce fan power consumption, reduce noise and wear, prevent engine overheating, reduce pollution, and save fuel, fan clutches are often used. In the traditional silicon oil fan clutch, the deflection of the valve plate is controlled by the thermosensitive spiral bimetal spring temperature sensor, so the response time has a certain lag, and the control accuracy will be limited. Summary of the invention: [0003] The technical problem solved by the present invention is to provide a mechanism for controlling the silicon oil fan clutch on an automobile with simple structure and r...
