Efficient flow-guide electric-control silicone oil fan clutch assembly

Abstract

The invention discloses an efficient flow-guide electric-control silicone oil fan clutch assembly. The clutch assembly comprises a driving shaft (2), a shell (6), a driving plate (7), a driven plate (10) and a front cover (12), wherein a fan (16) is arranged on the shell, a solenoid valve component (3) is arranged on the driving shaft, a magnetic conducting piece (11) is arranged on the driving plate and close to the driving shaft, an oil storage chamber (9) is arranged on the driving plate and between the driving plate and the driven plate, a circulating oil way (17) communicated with the oil storage chamber (9) is arranged in the front cover, and a working cavity (18) communicated with the oil storage chamber and the circulating oil way is arranged between the shell and the driving plate as well as the front cover and the driving plate. With the fan clutch assembly, the circulating and flowing speed of the silicone oil can be raised, the meshing response time and the separating response time between the driving part and the driven part of the fan clutch assembly are relatively shortened, and the rotating speed of the fan is controlled in real time, so that an engine runs at an optimal temperature all the time, and the purposes of energy saving, emission reduction and noise reduction of an automobile are realized.

Description

technical field [0001] The invention relates to an engine cooling system, in particular to a silicone oil fan clutch assembly applied to an automobile engine cooling system. Background technique [0002] At present, the silicone oil fan clutch assembly is an important part of the engine cooling system on the car, which plays a key role in the energy saving, emission reduction, noise reduction and prolonging the service life of the car. The electronically controlled silicone oil fan clutch assembly replaces the original temperature-sensitive silicone oil fan clutch assembly, which controls the engagement and disengagement response time of the active part and the driven part of the fan clutch assembly through the circulating flow speed of the electronically controlled silicone oil, and The sensor board and the hall sensor in the solenoid valve assembly are used to feed back the fan speed signal in real time to achieve accurate closed-loop control, so that the engine can run at...

AI Technical Summary

Problems solved by technology

The magnetic guide sheet (also known as the valve sheet) of the existing electronically controlled silicon oil fan clutch assembly is installed on the front cover, which belongs to a part of the driven assembly, and forms electromagnetic induction with the solenoid valve assembly, and the centrifugal force it receives is compared with the oil return force. Small, the circulation speed of electronically controlled silicon oil is relatively slow, and the response time for the engagement and disengagement of the active part and the driven part of the fan clutch assembly will be prolonged accordingly, thus affecting the best working state of the engine to a certain extent
