Electric control silicon oil fan clutch

Abstract

The invention relates to the field of automobile engine cooling systems, in particular to an electric control silicon oil fan clutch. The clutch comprises a front cover, a shell, a driving shaft, a driven plate, a driving plate, valve blocks, a counting ring and a magnetic yoke coil, wherein the front cover and the shell are assembled through bolts and sealed to form an oil storage cavity, a working cavity and a flow channel; the driven plate is arranged on the driving plate; the driving plate is assembled on the driving shaft and is coaxial with the driving shaft; the driving shaft is arranged on a central shaft of the front cover and the shell, and assembled on the shell; the top end of the driving shaft is positioned in the front cover; the magnetic yoke coil is arranged around the driving shaft; the driving shaft is composed of a shaft body and a magnetic conduction column; the magnetic conduction column is positioned at the top end inside the shaft body; the shaft body and the magnetic conduction column are coaxially arranged; the two ends of the axis center of the driving plate are each provided with one valve block; one end of each valve block is arranged on the driving plate, and the other end of each valve block is away from the driving plate due to elasticity; corresponding to the lower part of each valve block, an oil inlet hole is formed in the driving plate; and the counting ring is arranged in the shell. According to the clutch, the service life of the clutch is prolonged, the cost is reduced, and the response speed is increased.

Description

technical field [0001] The invention relates to the field of automobile engine cooling systems, in particular to an electronically controlled silicon oil fan clutch. Background technique [0002] With the development of the country's economy, the requirements for energy saving and environmental protection of automobiles are getting higher and higher. Most of the working time of automobiles does not need fan cooling, so the automatic fan clutch technology of automobiles is a key technology for automobile energy saving. As the core component of the automobile engine cooling system, the electronically controlled silicon oil fan clutch has an important impact on the performance of the engine. [0003] Some existing electronically controlled silicon oil fan clutches have a one-piece structure formed by crimping between the shell and the front cover. This structure is not conducive to assembly and later maintenance. It is a great waste to solve the problem by replacing it with a ...
