Description

Technical Field

[0001] The utility model relates to the technical field of electronic control clutches, in particular to a long-life electronic control clutch. Background Technique

[0002] The clutch is installed between the engine and the transmission, and is a component directly connected to the engine in the automotive drive train. Usually, the clutch is installed together with the flywheel group of the engine crankshaft, and is a component that cuts off and transmits power between the engine and the automotive drive train. During the entire process from starting to normal driving of the vehicle, the driver can operate the clutch as needed to temporarily separate or gradually engage the engine and the drive train, so as to cut off or transmit the power output from the engine to the drive train. Its function is to gradually engage between the engine and the transmission, so as to ensure the smooth start of the vehicle.

[0003] For example, the authorized announcement number "CN212744779U" is a new type of temperature-controlled silicone oil clutch. Although the use of this structure of the clutch makes the oil outlet rate of the clutch stable and improves the stepless control ability of the clutch. However, for this structure of the clutch, when the temperature sensor senses that the engine temperature rises, the control valve shaft rotates through the thermal deformation of the temperature sensor. Once the temperature sensor is damaged or the deformation is not in place, the control valve shaft cannot be rotated, affecting the service life of this structure of the clutch.

The hydraulic cylinder 20 is electrically connected to the trigger button 18. A telescopic rod 21 is provided on one side surface of the hydraulic cylinder 20. A first bearing block 22 is sleeved on the surface of the telescopic rod 21. One end of the telescopic rod 21 penetrates through the first oil outlet hole 13 and is provided with a first sealing block 23. A first spring 24 is provided on one side surface of the first bearing block 22. The other end of the first spring 24 is connected to the driving plate 6. A second temperature sensor 25 is provided on the upper surface of the driving plate 6. An electric opening device is provided inside the second oil outlet hole 14.

[0021] The electric opening device includes a slide bar 26. The lower end of the slide bar 26 penetrates through the second oil outlet hole 14 and is provided with a second bearing block 27. A second sealing block 28 is provided on the upper end of the slide bar 26. A permanent magnet 29 is provided on the upper surface of the second bearing block 27. A coil 30 is provided on the lower surface of the driving plate 6. The coil 30 is matched with the permanent magnet 29. A second spring 31 is provided between the lower surface of the driving plate 6 and the upper surface of the second bearing block 27. The coil 30, the rotation sensor 19, and the second temperature sensor 25 are electrically connected.

[0022] On the upper surface of the fan body 15, there are multiple additional fan blades 32, which correspond one by one to the multiple fan blades provided on the fan body 15. The inclination direction of the additional fan blades 32 is the same as that of the fan blades provided on the fan body 15. The additional fan blades 32 rotate together with the fan body 15 to increase the air output, and at the same time, the additional fan blades 32 also play a role in reinforcement.

[0023] On the upper surface of the middle part of the fan body 15, there are multiple first reinforcing ribs 33 provided in a ring shape. The first reinforcing ribs 33 play a role in reinforcing the fan body 15.

[0024] On the inner wall of the fan body 15, there are multiple second mounting blocks 34 provided in a ring shape, and mounting holes 35 are provided on the surfaces of the multiple second mounting blocks 34. For the provided mounting holes 35, bolts pass through the mounting holes 35 and are threadedly connected to the cover body 5.

[0025] On the surface of the housing 4, there are multiple second reinforcing ribs 36. The second reinforcing ribs 36 play a role in reinforcing the housing 4.

[0026] Working principle: For the provided first temperature sensor 17, when it senses that the engine temperature rises, the first temperature sensor 17 is deformed by heat and presses the trigger button 18, so that the hydraulic cylinder 20 is started, the telescopic rod 21 extends, and further the first sealing block 23 is separated from the first oil outlet hole 13. The silicone oil in the oil storage chamber 9 enters the working chamber 11 under the action of centrifugal force. Through the viscosity of the silicone oil, the housing 4 and the cover body 5 rotate together with the driving plate 6; when the first temperature sensor 17 senses that the engine temperature drops, the first temperature sensor 17 resets, the hydraulic cylinder 20 closes, and under the action of the compression force of the first spring 24, the first bearing block 22 is pushed to move leftward, so that the first sealing block 23 closes the first oil outlet hole 13, and at the same time, the silicone oil returns to the oil storage chamber 9 through the oil return pressure pump 12 and the oil return channel 10, and the clutch enters the separated state.

[0027] When the first temperature sensor 17 fails and the engine temperature rises, the second temperature sensor 25 senses the temperature rise. At the same time, the rotation sensor 19 detects that the fan body 15 does not rotate. At this time, an electric opening device is provided. The coil 30 is energized, so that the coil 30 and the permanent magnet 29 attract each other as opposite magnetic poles, and the second sealing block 28 is separated from the second oil outlet hole 14. The silicone oil in the oil storage chamber 9 enters the working chamber 11 under the action of centrifugal force. Through the viscosity of the silicone oil, the housing 4 and the cover body 5 rotate together with the driving plate 6. When the second temperature sensor 25 senses that the engine temperature drops, the second temperature sensor 25 resets, the coil 30 is powered off, and under the action of the compression force of the second spring 31, the second bearing block 27 is pushed to move downward, so that the second sealing block 28 closes the second oil outlet hole 14, and at the same time, the silicone oil returns to the oil storage chamber 9 through the oil return pressure pump 12 and the oil return channel 10, and the clutch enters the separated state.

[0028] The original electromagnetic clutch is replaced by the circuit device 1 and the temperature-controlled clutch body 2: Since the operation of the electromagnetic clutch is similar to that of a brake pad, the fan needs to reach the engagement speed through hard connection by friction. This results in several unavoidable disadvantages of the electromagnetic clutch: 1. Short service life, usually only 6 months, and it is time-consuming and laborious to replace the friction plate when the service life expires; 2. The hard connection causes great damage to the crankshaft in an instant; 3. The hard connection causes the fan speed to increase instantaneously, resulting in a jerky feeling for the whole vehicle and a poor customer experience.

[0029] The electromagnetic clutch is changed to the circuit device 1 and the temperature-controlled clutch body 2, which can not only enable the whole vehicle to recognize the existence of the clutch through the circuit, but also greatly increase the service life of the clutch. The service life of the temperature-controlled clutch is usually 2 years or 150,000 kilometers. Since the temperature-controlled clutch uses silicone oil as the medium to transmit torque inside, the speed change is smooth and the torque change is flexible when the fan engages, which not only protects the crankshaft from the influence of instantaneous torque change but also improves the customer experience.

[0030] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
