Abstract

The invention relates to a silicon oil fan clutch, comprising a shell and a front cover; wherein, the front cover and the shell are connected in a sealing way to form internal space, the internal space is provided with an oil storage cavity and a gearing cavity, and a valve plate which controls flow of silicon oil between the oil storage cavity and the gearing cavity is arranged between the oil storage cavity and the gearing cavity; the invention is characterized in that the clutch also comprises an electromagnet which can pull in the valve plate after electricity is supplied and a temperature controlled switch which controls whether the electromagnet works or not; the electromagnet comprises an iron core and a coil arranged on the iron core, the valve plate is elastic, and with no force imposed upon, the valve plate opens an oil storage control hole through which the oil storage cavity leads to the gearing cavity owing to self-elasticity. Compared with the prior art, the silicon oil fan clutch has the advantages of eliminating a temperature sensing ring of the traditional silicon oil fan clutch and adopting an electric control unit, thus enjoying the advantages of high precision,quick response and wide range of temperature control.

Description

technical field

[0001] The invention relates to an engine cooling system assembly, in particular to a silicone oil fan clutch. Background technique

[0002] Saving energy is a long-term policy of the country's economic development. According to relevant research data, 5-10% of the energy of the car is consumed by the fan cooling of the engine. In fact, the car does not need fan cooling for most of the working time, and generally only 5-10% of the time requires fan cooling. The fan automatic clutch technology is an important key technology for automobile energy saving. For this reason, many technicians have carried out technical improvements to the fan automatic clutch. They generally adopt the structure of bimetallic temperature sensing parts, through which the bimetallic temperature sensing parts feel the temperature of the air blown from the radiator to produce thermal deformation to control the switch of the valve.

Embodiment

[0021] Example: Reference figure 1 with figure 2 shown.

[0022] The fan silicone oil clutch in this embodiment includes a driving shaft 1, a housing bearing 2, a housing 3, a front cover 5, a driving plate 6, a valve plate 7, an oil storage cover 8, an electromagnet 90 and an electromagnet bearing 12 . The housing 3 is inserted on the driving shaft 1 through a housing bearing 2 .

[0023] The drive shaft 1 is fixed in the middle of the housing 3 through the housing bearing 2, and the sealing ring 4 is fixedly connected between the front cover 5 and the housing 3; Engagement cavity 14; valve plate 7 has elasticity, one end of valve plate 7 is inlaid on active plate 6, and the other end is a free end that can open and close oil storage control hole 16. The active plate 6 is provided with a limiting hole 61 for limiting the valve plate 7 .

[0024] The oil storage cover 8 is fixedly connected with the active plate 6 to form an oil storage chamber 13, and there is silicone ...
