Technical Field

The invention relates to the field of silicone oil fan clutches, in particular to a novel temperature control silicone oil clutch capable of being quickly separated.

Background

With the domestic advancement of the national six-emission standard, the vehicle puts higher requirements on the silicone oil clutch. Such as improved cooling capacity, reduced power consumption, reduced fan noise, etc. However, the traditional silicone oil clutch fan has long separation time and slow response, which easily causes the water temperature of the engine to be incapable of being stably controlled, and causes high water temperature or oil consumption of the engine, high noise of the fan and large impact on a cooling system. Therefore, a silicone oil clutch needs to be designed, and the stepless characteristic and the response time of the clutch are further improved.

The oil return channel of the traditional temperature control silicone oil clutch is arranged on the end cover, the oil return speed is low, and the response capability of the clutch is poor.

Disclosure of Invention

The technical scheme is as follows: in order to achieve the above object, the present invention provides a temperature controlled silicone oil clutch with rapid response, which comprises: by the working chamber that forms between casing, initiative board and the lid, formed the oil storage chamber by lid and driven plate, it still includes: the oil storage device comprises a valve sheet shaft, wherein one end of the valve sheet shaft is connected with the valve sheet, the other end of the valve sheet shaft is connected with a temperature sensor, the end part of the valve sheet is attached to a driven plate and can move relatively, an oil return channel and an oil return pressure pump located on one side of the oil return channel are arranged on the driving plate, one end of the oil return channel extends into the oil storage chamber, and the other end of the oil return channel extends to the outer edge of the driving plate.

As a further preferred aspect of the present invention, the temperature sensor senses thermal deformation when the temperature of the engine rises, the temperature sensor is formed by attaching bimetallic strips having different thermal coefficients, and when the temperature sensor is heated, the deformation amounts of the two metal strips are changed to control the rotation and the return of the valve piece shaft.

As a further preferred aspect of the present invention, the driven plate is provided with an oil outlet, the temperature sensor controls the rotation of the valve plate shaft to drive the valve plate to move relative to the driven plate, and the opening and closing of the oil outlet is realized by the movement of the valve plate relative to the driven plate.

As a further optimization of the invention, the end part of the valve plate is opposite to the oil outlet, when the valve plate is abutted to the oil outlet, the oil outlet is closed, when the valve plate rotates for an angle, the positions of the valve plate and the oil outlet are staggered, the oil outlet is opened, and the silicone oil rapidly enters the working cavity from the storage chamber.

As a further preferred aspect of the present invention, the driving plate is provided with an oil groove.

As a further preferable mode of the invention, the outermost ring of the oil groove is provided with a slope, so that the silicone oil is better gathered at the oil return pressure and pumped out, the oil return pressure is increased, and the oil return speed is accelerated.

As a further preferred embodiment of the present invention, the number of the oil return pressure pumps and the oil return channels is proportional to the size of the driving plate, and the larger the size of the main plate is, the larger the pressure caused by the centrifugal force that needs to be overcome for oil return is, the harder it is to return oil, and at this time, if the oil return speed needs to be further increased, the number of the oil return pressure pumps and the oil return channels needs to be increased.

Has the advantages that: compared with the prior art, the temperature control silicone oil clutch with quick response has the following advantages:

1. the oil return pressure pump and the oil return channel are changed from the end cover to the active plate, because the active plate has higher rotating speed and higher oil return pressure than the end cover, the silicone oil can quickly return to the oil storage chamber, and the separation response time is accelerated by more than 40 percent under the condition of matching with the same fan;

2. the design can lead the silicone oil clutch of the fan to be quickly separated, and reduce oil consumption;

3. when the vehicle is in cold start, the silicone oil clutch of the fan can be quickly separated, which is beneficial to the heat engine of the engine;

4. the stepless control capacity of the clutch is improved;

5. the whole energy consumption of the automobile is reduced, the noise is reduced, and the driving comfort is improved.

Detailed Description

The invention is further elucidated with reference to the drawings and the embodiments.

As shown in the attached drawings, the invention relates to a quick-response temperature-control silicone oil clutch, which comprises: the oil-water separator comprises a driving shaft 1, a bearing 2, a shell 3, a driving plate 4, a cover body 5, a driven plate 6, a valve plate 7, a valve plate shaft 8, a temperature sensor 9, an oil storage chamber 10 and a working cavity 11, wherein one end of the valve plate shaft 8 is connected with the valve plate 7, the other end of the valve plate shaft 8 is connected with the temperature sensor 9, the end part of the valve plate 7 is attached to the driven plate 6 and can move relatively, the driving plate 4 is provided with an oil return pressure pump 41 and an oil return channel 42, one end of the oil return channel 42 extends into the oil storage chamber 10, the other end of the oil return channel 42 extends to the outer edge of the driving plate 4, and when the driving plate 4 rotates, silicone oil returns to the oil storage chamber 10 through the oil return pressure pump 41 and the oil return channel 42.

The temperature sensor 9 is formed by attaching bimetallic strips, when the temperature sensor 9 is heated, the deformation of the two bimetallic strips changes to control the rotation of the valve plate shaft 8, and when the temperature sensor 9 senses the temperature reduction of the engine, the bimetallic strips on the temperature sensor 9 reset to drive the valve plate shaft 8 to reset.

When the temperature sensor 9 senses that the temperature of the engine rises, the temperature sensor 9 is heated to deform to control the valve plate shaft 8 to rotate, so that the valve plate 7 is driven to rotate in one direction, the end part of the valve plate 7 opens the oil outlet 61 on the driven plate 6, the silicone oil enters the working cavity 11 through centrifugal force, the clutch enters a coupling state, and the silicone oil transmits power to the shell and the end cover to drive the fan to rotate at high speed, so that the heat of the engine is reduced.

When the temperature sensor 9 senses that the temperature of the engine is reduced, the bimetallic strip on the temperature sensor 9 resets to drive the valve shaft 8 and the valve plate 7 to rotate in the opposite direction to reach a reset state, the end part of the valve plate 7 abuts against the oil outlet 61 on the driven plate 6, so that the oil outlet 61 is closed, at the moment, silicone oil returns to the oil storage chamber 10 through the oil return pressure pump 41 and the oil return channel 42, and the clutch enters a separation state.

Because the rotation speed of the driving plate 4 is higher than that of the end cover 5, and the oil return pressure is large, under the condition of matching the same fan, the separation time of the clutch is reduced by about 40% by additionally arranging the oil return pressure pump 41 and the oil return channel 42. The oil return system is optimized, the clutch separation time is reduced, the stepless characteristic and the response capability of the clutch are improved, and the oil consumption and the noise are reduced.
