Problems solved by technology

The disadvantage of this structure is: because the electromagnetic control valve switch assembly contains a magnetic coil, and the Hall principle adopted by the fan speed measurement assembly also contains a permanent magnet, when the speed is measured, the strong magnetic field generated by the energized magnetic coil will It has a certain impact on the magnetic field signal received by the Hall element, causing the magnetic signal to weaken, and the Hall element cannot receive the normal magnetic signal, resulting in inaccurate measured rotational speed, and the output of the rotational speed data to the central processor is incorrect, resulting in a central The adjustment of the processor is delayed or not adjusted at all, which consumes the energy of the engine, which is not conducive to energy saving and environmental protection

Abstract

The invention provides a clutch for an electric control silicon-oil fan. The clutch comprises a driving shaft, a shell arranged on the driving shaft through a bearing, a drive plate fixed on the driving shaft, and a driven plate fixed on an end cover, wherein the fan is arranged on the driven plate; the end cover and the shell are fixed into a whole; an oil storage cavity and a work cavity are arranged between the driven plate and the shell, and are communicated through an oil feed hole and an oil return hole; an electromagnetic control switch controls the open and close of the feed hole, and is fixed on the driving shaft and positioned at the back of the shell; a fan rotating speed test component is arranged between the electromagnetic control switch and the shell, and an electromagnetic shielding layer is arranged between the fan rotating speed test component and the electromagnetic control switch; and the fan rotating speed test component transmits a test signal to a central processor. The structure has the function of energy conservation, is environmental friendly, and can accurately test data.

Description

Technical field [0001] The invention relates to a silicone oil fan clutch for a motor vehicle. Background technique [0002] The silicone oil fan clutch uses silicone oil as the medium and uses the high viscosity of silicone oil to transmit torque. The temperature of the air behind the radiator is used to automatically control the separation and engagement of the fan clutch through a temperature sensor. When the temperature is low, the silicone oil does not flow, the fan clutch is separated, and the fan speed slows down, basically idling. When the temperature is high, the viscosity of the silicone oil causes the fan clutch to be combined, so the fan and the water pump shaft rotate together to adjust the engine temperature. Silicon oil fan clutch, temperature sensing element is bimetallic coil spring temperature sensor. [0003] Its working process: [0004] (1) When the temperature of the air flowing through the radiator rises, the bimetallic temperature sensor is heated and defo...
