Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further explained in the following with the accompanying drawings and the specific embodiments.
DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
As shown in fig. 1-4, in the electric control silicone oil fan clutch for both forward and reverse rotation provided by the embodiment of the invention, one end of a main shaft 1 is connected with an engine output shaft through a bolt, a wire harness assembly 2, a housing 3, a main board 5 and a front cover 6 are arranged outside the other end of the main shaft 1, the main shaft 1 and the main board 5 are in interference connection, the main board 5 and the main shaft 1 are driven by the engine output shaft to simultaneously operate, the housing 3 is connected with the front cover 6 through a bolt to form a driven assembly, and the driven assembly is driven to rotate together through silicone oil viscosity when the main board and the main shaft rotate, so that a rotation speed difference exists between the main board 5 and the driven assembly; still be equipped with out oil passageway 8 and oil return passage 11 on mainboard 5, oil passageway 8 and oil return passage 11 and the oil storage chamber 7 intercommunication that is equipped with respectively, all be equipped with silicon oil in the oil storage chamber 7, oil passageway 8 and oil return passage 11 both sides are equipped with working chamber 9, just oil passageway 8 and oil return passage 11 are equipped with the frizing pond 10 that communicates with it respectively, oil passageway 8 with be equipped with between the oil storage chamber 7 oil-out 12.
In addition, the oil return passage 11 is specifically divided into a forward oil return passage Z and a reverse oil return passage F; one end of the valve plate assembly 4 is fixedly connected with the main board 5, and the other end of the valve plate assembly 4 is used as an opening and closing switch of the oil outlet 12.
It is worth mentioning that the wire harness assembly 2 can modulate the running rotating speed of the fan clutch by controlling the electromagnetic force, and the control process is specifically that when the wire harness is connected with a power supply, the electromagnetic force is generated so as to adsorb the valve plate assembly 4, at the moment, the oil outlet 12 is closed, and the fan clutch is in a low-speed running state; when the wire harness assembly 2 is connected with or disconnected from a power supply, the electromagnetic force disappears, so that the wire harness assembly is disconnected from the valve plate assembly 4, the oil outlet 12 is opened, and the fan clutch is in a high-speed running state.
When the silicone oil fan clutch operates, the silicone oil flows out of the oil storage cavity 7 and rapidly flows into the working cavity 9 and the oil scraping pool 10 through the oil outlet channel 8 under the action of centrifugal force, in order to enable the silicone oil to get rid of the centrifugal force, the pressure is increased in the oil scraping pool 10, and the silicone oil returns to the oil storage cavity 7 through the oil return channel 11; when the clutch rotates clockwise, the silicone oil returns to the oil storage cavity 7 from the forward oil return channel Z, and the reverse oil return channel F is empty; when the clutch rotates anticlockwise, the silicone oil returns to the oil storage cavity 7 through the reverse oil return channel F, and the forward oil return channel Z is empty at the moment.
The working principle of the invention in the specific embodiment is as follows:
the engine output shaft drives the main board 5 and the main shaft 1 to run simultaneously, and the main board 5 and the main shaft 1 drive the driven assembly to run asynchronously through the viscosity of silicone oil when rotating; the wiring harness assembly 2 is further used for modulating the running rotating speed of the fan clutch by controlling electromagnetic force through controlling power-on and power-off, and the control process is specifically that when the wiring harness assembly is powered on, the wiring harness assembly generates electromagnetic force to adsorb the valve plate assembly 4, the oil outlet 12 is closed, and the fan clutch is in a low-speed running state; when the wire harness assembly 2 is connected with or disconnected from a power supply, the electromagnetic force disappears, so that the valve plate assembly 4 bounces, the oil outlet 12 is opened, and the fan clutch is in a high-speed running state.
When the silicone oil fan clutch operates, silicone oil flows out of the oil storage cavity 7 and rapidly flows into the working cavity 9 and the oil scraping pool 10 through the oil outlet channel 8 under the action of centrifugal force, and because the main board 5 and the shell 3 have a rotation speed difference, the silicone oil swings out of a central force under the action of pressurization in the oil scraping pool 10 and returns to the oil storage cavity 7 through the oil return channel 11; specifically, when the clutch rotates clockwise (forward), silicone oil returns to the oil storage chamber 7 through the forward oil return passage Z, and the reverse oil return passage F is empty at this time; when the clutch rotates anticlockwise (reversely), the silicone oil returns to the oil storage cavity 7 through the reverse oil return channel F, the forward oil return channel Z is empty, and the circulation is repeated and fast so as to meet the functional requirement of the clutch.
The invention relates to a positive and negative rotation dual-purpose electric control silicone oil fan clutch, which does not rigidly require the rotation direction of a main shaft during matching. The rotary disc can rotate forward or backward along with the main shaft, and all functions of product meshing, closing, rotating speed modulation and the like are met.
