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
The invention provides a positive and negative rotation dual-purpose silicone oil fan clutch as shown in fig. 1-4, which is characterized by comprising a main shaft 6 connected with an engine output shaft through a bolt, a main board 4 in interference fit connection with the main shaft 6, and a driven shell formed by connecting a front cover 3 and a shell assembly 5 through a bolt, wherein the main shaft 6 and the main board 4 are driven by the engine output shaft to synchronously rotate, and the main board 4 and the main shaft 6 drive the driven shell to asynchronously rotate through silicone oil viscosity when synchronously rotating, so that a rotation speed difference exists between the main board 4 and the driven shell. In addition, still including locating oil outlet channel 8, the oil return passageway 11 on mainboard 4, oil outlet channel 8 and 11 one end of oil return passageway communicate with oil storage chamber 7, and the oil outlet channel 8 and the oil return passageway 11 other end are connected with frizing pond 10, oil outlet channel 8 and 11 both ends of oil return passageway are equipped with working chamber 9 in addition.
An oil outlet is formed at the communication position of the oil outlet channel 8 and the oil storage cavity 7, and the medium in the oil storage cavity 7 is silicone oil; the oil outlet department is equipped with valve block 2, and valve block 2 is controlled in temperature sensor 1 and is driven, and 3 middle parts of protecgulums are located to temperature sensor 1 clamp, and valve block 2 is used for acting as the on-off switch of oil-out, and temperature sensor 1 is used for gathering the data of ambient temperature change, drives valve block 2 rotation through spontaneous deformation to control the state that opens and shuts of oil-out.
The oil return passage 11 is specifically a forward oil return passage Z and a reverse oil return passage F, and the working conditions of the oil return passage Z and the reverse oil return passage F meet the following conditions: 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 vacant at the moment; 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:
when the silicone oil fan clutch operates, the temperature sensor collects the external temperature, then the valve plate is driven to rotate, the oil outlet is gradually opened at the moment, 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; because the main board and the shell have a rotation speed difference, the silicone oil swings away from the central force under the pressurization effect in the oil scraping pool and returns to the oil storage cavity 7 through the oil return channel 11.
In the specific process of returning the silicone oil to the oil storage cavity 7 through the oil return channel 11, when the clutch rotates clockwise (forward), the silicone oil returns to the oil storage cavity 7 through the forward oil return channel Z, and at the moment, the reverse oil return channel F is empty; 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 forward and reverse rotation dual-purpose silicone oil fan clutch which does not require the rotation direction of a main shaft rigidly during matching and can rotate forward or reversely along with the main shaft, thereby meeting all functions of product meshing, closing, rotating speed modulation and the like.
