Problems solved by technology

The above solution fixedly connects the oil-containing convex ring to the outer circle of the driving disc, which is difficult to process and high in production cost, and its oil-repelling groove runs through the oil-containing convex ring. During the rotation of the driving disc, silicone oil can easily enter the working chamber from both sides of the oil-containing convex ring. And flow back to the oil storage chamber through the oil return channel, resulting in a decrease in the speed of the silicone oil fan clutch in the disengaged state

Embodiment Construction

[0027] The embodiments of the present invention will be further detailed below in conjunction with the accompanying drawings:

[0028] The core point of the present invention is that the system for different wind resistance can control the separation speed of the silicone oil fan clutch at an appropriate level, so that the negative pressure generated by the fan rotation under the separation condition can make the air flow overcome the wind resistance of the cooling system to reach the bimetal Around the temperature sensor, so that the bimetallic temperature sensor can sense the water temperature in the radiator 7 in time, and ultimately ensure that the engine works within a reasonable temperature range.

[0029] See Figure 1 to Figure 6 , The embodiment of the silicone oil fan clutch 100 with controllable separation speed provided in accordance with the present invention includes a sealed bearing, a housing mounted on the outer ring 91 of the sealed bearing, and a drive shaft mount...

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...
