Abstract

The invention relates to a silicone oil fan clutch with controllable separation speed. The silicone oil fan clutch with controllable separation speed comprises a sealed bearing, a shell arranged on an outer ring of the sealed bearing and a driving shaft arranged on the inner ring of the sealed bearing. A driving disc is arranged on the driving shaft, the driving disk is arranged in the shell, and an oil storage cavity is formed in the shell. An oil-guiding groove is formed in an outer cylindrical surface of the driving disc, and a raised rib strip is also arranged on the outer cylindrical surface of the driving disc. The silicone oil fan clutch with controllable separation speed provided by the invention has the advantages that a raised rib strip is further arranged on the outer cylindrical surface of the driving disc, when the silicone oil fan clutch transforms from a meshed mode into a separated mode, the rib strip can guide a fraction of silicone oil into a clearance between the outer cylindrical surface of the driving disc and the shell from a clearance between the upper portion of the driving disc and the shell, an oil pressure zone with certain pressure is formed on one side of the rib strip, the additional transmission function is generated in this way, and the separation speed of the silicone oil fan clutch is improved.

Description

Technical field

[0001] The invention relates to a silicon oil fan clutch, in particular to a silicon oil fan clutch used for a cooling fan of an automobile engine. Background technique

[0002] With the development of the national economy, the requirements for energy saving and environmental protection of automobiles are getting higher and higher. As one of the core components of the automobile engine cooling system, the silicone oil fan clutch has an important influence on the performance of the engine. As modern vehicles are equipped with air conditioning systems and turbochargers, condensers and intercoolers are generally installed at the front of the radiator, which makes the wind resistance of the engine cooling system larger than that of the traditional vehicle engine cooling system. At present, the separation speed of the bimetal thermosensor type silicone oil fan clutch is uncontrollable, and the speed is low during separation, which causes the fan installed on the drive...
