Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The electrically controlled silicone oil clutch with a front connector assembly as shown in fig. 2 and 3 mainly includes a driving component, a cover component and a connector assembly 8.
The driving assembly comprises a driving shaft 1 and a driving plate 4, wherein the driving plate 4 is sleeved at one end of the driving shaft 1, and a first tooth groove is formed in the periphery of the driving plate 4. In the present embodiment, the diameter of the driveshaft 1 decreases from one end to the other end in the direction of the axis thereof, so that a plurality of steps (which can be used for mounting other parts such as bearings) are formed on the driveshaft 1; the active plate 4 is mounted at the end portion (defined as the outer end portion) having a smaller diameter. The driving plate 4 and the driving shaft 1 are fixedly connected through conventional fasteners such as splines, so that when the driving shaft 1 rotates, the driving plate 4 synchronously rotates; and the first gullets are formed at the edges of the outer surface of the driving plate 4.
The cover assembly mainly comprises a bearing 2, a shell 3, a cover 5, a driven plate 6 and the like. The casing 3 is rotatably sleeved on the driving shaft 1 through the bearing 2, so that the rotation of the driving shaft 1 does not influence the casing 3. The cover body 5 is covered on the shell 3 and forms a certain interval with the outer end part of the driving shaft 1; in the present embodiment, the edges of the cover 5 and the housing 3 are fixed by riveting, welding, etc. in a conventional manner, so that the cover 5 and the housing 3 move synchronously (an accommodating space is formed between the cover 5 and the housing 3, and the active plate 4 is located in the accommodating space). The driven plate 6 is fixed in the cover 5 (the driven plate 6 is also located in the accommodating space and is disposed opposite to the driving plate 4), and at least one oil outlet hole 61 is formed in the driven plate (the specific number and position of the oil outlet holes 61 are determined according to actual requirements, in this embodiment, the oil outlet holes 61 are one and close to the edge of the driven plate 6). The valve plate 7 is installed in the cover body 5 (the valve plate 7 is also located in the accommodation space), and has an extension portion that extends between the driving plate 4 and the driven plate 6 and is fitted with the oil outlet 61.
In this embodiment, the cover body 5 has a second tooth groove matched with the first tooth groove, so that a working cavity 9 is formed between the first tooth groove and the second tooth groove, an oil storage chamber 10 is formed between the driven plate 6 and the cover body 5, and at least one set of oil return channels communicated with the oil storage chamber 10 (the specific number may be determined according to actual requirements, that is, one end of each oil return channel is communicated with the oil storage chamber 10) and oil return holes communicating each set of oil return channels with the corresponding second tooth groove are formed in the cover body 5 (that is, the oil return holes are communicated with the working cavity 9, so that the oil return holes communicate each set of oil return channels with the working cavity 9).
The connector assembly 8 is mounted on the outer wall of the cover 5 for attracting the valve sheet 7 to open or close the oil outlet hole 61. In the present embodiment, the connector assembly 8 includes a connection holder having an end portion embedded in the cover 5, a center shaft having an end portion inserted into the center of the connection holder and sealed by a seal, a coil mount mounted on the center shaft through a bearing, and a solenoid coil provided on the coil mount (so that the solenoid coil does not rotate with the center shaft). The connector assembly 8 has two states of power-on and power-off, when the connector assembly is in the power-on state, the connector assembly generates magnetic force to attract the valve plate 7, and the extending part of the connector assembly shields the oil outlet 61; when the valve plate is in the power-off state, the valve plate 7 is reset, and the extending part of the valve plate does not shield the oil outlet 61 any more.
In the embodiment, a limiting baffle plate 62 is arranged on the surface of the driven plate 6 opposite to the driving plate 4; when the connector assembly 8 is in the power-off state, the extending part of the valve plate 7 abuts against the limiting stop piece 62, so that the valve plate 7 is prevented from being sucked too far away from the connector assembly 8. The driven plate 6 is provided with a boss portion facing the driving plate 4, and the oil outlet 61 is opened in the boss portion, which facilitates sealing of the oil outlet 61 by the extension portion of the valve sheet 7. The distance between the limiting baffle plate 62 and the center of the driven plate 6 is smaller than the distance between the oil outlet 61 and the center of the driven plate 6, namely, the oil outlet 61 is positioned outside the limiting baffle plate 62 (as shown in fig. 4 and 5).
In this embodiment, the valve sheet 7 includes a spring sheet 71 having one end mounted on the inner wall of the cover 5 through the connecting seat 70 and a partial structure of the valve sheet body or the extension part mounted on the surface of the spring sheet 71, and the valve sheet body 72 is located in the oil chamber 10. Specifically, the driven plate 6 has an avoiding hole 63 formed in the middle thereof, and the extending portion extends between the driving plate 4 and the driven plate 6 through the avoiding hole 63.
In this embodiment, as shown in fig. 6 and 7, the valve plate body 72 includes a supporting plate body 721 and a through hole 722 formed at an end of the supporting plate body 721, and the end of the supporting plate body 721 provided with the through hole 722 is far away from the connecting seat 70. The through hole 722 further extends to the outermost point of the end of the supporting sheet 721 to form a double-lug structure, so that the through hole 72 avoids the oil outlet 61 of the driven plate 6, and the double-lug structure is also beneficial to reducing the contact area between the valve plate body 72 and the cover body 5, thus when the clutch is powered off, the oil outlet rate can be increased after the valve plate 7 is bounced, and the fan can be coupled quickly.
The elastic sheet 71 includes a bearing sheet 712, an adapter sheet 711 integrally connected to one end of the bearing sheet 712 and connected to the connecting base 70 (the adapter sheet 711 extends toward the driven plate 6), and a bending sheet 713 integrally connected to the other end of the bearing sheet 712 and bent and extended between the driving plate 4 and the driven plate 6, wherein an outer end of the bending sheet 713 is the aforementioned extending portion (i.e., the elastic sheet 71 is generally an integrally formed structure).
The electric control silicone oil clutch arranged in front of the connector assembly has the following working principle:
when the whole vehicle (controlled by PWM pulse signal) powers off the connector assembly 8 (mainly an electromagnetic coil) of the electric control silicone oil clutch, the valve plate 7 resets under the elastic force of the elastic sheet 71 to bounce, the oil outlet 61 is opened, the silicone oil is acted by centrifugal force to enter the working cavity 9, the clutch enters a coupling state, the fan runs at high speed, and the cooling capacity is strong; when the whole vehicle (controlled by PWM pulse signal) energizes the connector assembly 8 of the electric control clutch, the valve plate 7 is deformed under the attraction of electromagnetic force to close the oil outlet 13, the silicone oil returns to the oil storage chamber 10, and the clutch enters a separation state.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
