The large pressing force clutch is matched with a heavy vehicle, and when the vehicle starts or shifts gears, the sliding friction of the large pressing force clutch can generate more heat, so that the friction material of the clutch exceeds a critical temperature value, and the friction coefficient is reduced; in addition, due to heavy load of the vehicle and poor operation habits, such as high-gear starting and the like, ineffective friction of the clutch is increased, the heat decline of the pressing force of the clutch is caused by overhigh temperature, the torque transmission capability of the clutch is reduced, and the phenomena of abnormal abrasion, clutch shaking, slipping and the like of the clutch are caused.

The following describes in detail specific structures and corresponding relationships between the components of the clutch heat dissipation system 100 provided in the present embodiment.
Fig. 1 is a schematic diagram of a clutch cooling system 100 according to an embodiment of the present disclosure.
As shown in fig. 1, the clutch heat dissipation system 100 includes a detector 10, a controller 11, and a control valve assembly 12. The clutch heat dissipation system 100 is used for the clutch assembly 20 and is used for dissipating heat of the clutch assembly 20.
The clutch assembly 20 is provided with a fluid inlet 245, the clutch assembly 20 belongs to a part of clutch, and the clutch comprises a clutch pedal 26, a gearbox clutch operating system 27 and an auxiliary air system 28 besides the clutch assembly 20. The detector 10 in the clutch heat dissipation system 100 is connected to the clutch pedal 26 for detecting whether the clutch pedal 26 is pressed down.
Specifically, the transmission clutch control system 27 includes a clutch master cylinder, a clutch slave cylinder, a release fork assembly, and the like. The auxiliary air system 28 includes an air pump, an air handling unit, a four-circuit protection valve, an auxiliary air valve, and the like. Since the transmission clutch control system 27 and the auxiliary air system 28 are respectively the same as the existing heavy vehicle technology, no further description is provided in this application.
The controller 11 is communicatively connected to both the detector 10 and the control valve assembly 12. The controller 11 is used for receiving the signal of the detector 10 and sending a command to control the action of the valve assembly 12. Specifically, when the detector 10 detects that the clutch pedal 26 is pressed down, the controller 11 controls the control valve assembly 12 to open, so that the fluid flowing through the fluid inlet 245 can flow through the clutch assembly 20, and heat is taken away in the process of flowing through the clutch assembly 20, so as to dissipate heat of the clutch assembly 20.
Further, the control valve assembly 12 includes a solenoid valve 13 and a fluid pipe 14, one end of the fluid pipe 14 is connected to the fluid inlet 245, the solenoid valve 13 is disposed on the fluid pipe 14 for blocking or allowing the fluid to flow into the clutch assembly 20 through the fluid pipe 14 and the fluid inlet 245. That is, when solenoid valve 13 is open, fluid flows through solenoid valve 13 through fluid line 14 into clutch assembly 20, and when solenoid valve 13 is closed, fluid flow into clutch assembly 20 ceases.
Further, the clutch heat dissipation system 100 further includes a fluid source 15, and the fluid source 15 is used for providing fluid to the clutch assembly 20. In this embodiment, the end of the fluid tube 14 remote from the fluid inlet 245 is connected to a fluid source 15.
When the solenoid valve 13 is in the open state, fluid from the fluid source 15 flows through the fluid tube 14 from the fluid inlet 245 into the clutch assembly 20.
It can be understood that the fluid in the present application may be gas or liquid, as long as clean air, other gas or liquid can be introduced into the clutch assembly 20 from the outside of the clutch assembly 20, and the flow of the fluid takes away heat to achieve the purpose of cooling and dissipating heat.
In this embodiment, the fluid is a gas, and the fluid source 15 is an auxiliary gas valve in the auxiliary gas system 28. With the help of the spare part among the prior art, can reduce newly-increased spare part, simple structure, convenient and practical.
Further, the clutch heat dissipation system 100 further includes a temperature sensor 16, the temperature sensor 16 is disposed in the clutch assembly 20, and the temperature sensor 16 is in communication with the controller 11.
The temperature sensor 16 is used for detecting the temperature in the clutch assembly 20, and the controller 11 receives the feedback signal of the temperature sensor 16 and controls the on/off of the control valve assembly 12, that is, the on/off of the electromagnetic valve 13, according to the judgment result of the real-time temperature detected by the temperature sensor 16 and the preset temperature after judgment.
When the real-time temperature detected by the temperature sensor 16 is higher than the preset temperature, which indicates that the temperature in the clutch assembly 20 is relatively high, heat dissipation is required, the electromagnetic valve 13 is continuously opened, and the fluid continues to flow through the clutch assembly 20.
When the real-time temperature detected by the temperature sensor 16 is lower than or equal to the preset temperature, which indicates that the temperature in the clutch assembly 20 is satisfactory, the controller 11 controls the electromagnetic valve 13 to close, and the fluid stops flowing into the clutch assembly 20.
Specifically, the clutch assembly 20 includes a flywheel 21, a driven plate 22, a clutch cover 23, an engine flywheel housing 24, and a transmission clutch housing 25. The flywheel 21 and the driven plate 22 are matched with each other, the clutch cover 23 is arranged on one side, far away from the flywheel 21, of the driven plate 22, the engine flywheel shell 24 and the gearbox clutch shell 25 are buckled with each other, the engine flywheel shell 24 is located on one side of the flywheel 21, and the gearbox clutch shell 25 is located on one side of the clutch cover 23.
When the vehicle starts to be in gear or is shifted, the clutch pedal 26 is slowly released, the driven plate 22 in the clutch assembly 20 generates sliding friction with the flywheel 21 and the clutch cover 23 simultaneously, heat is generated rapidly in the sliding friction process, finally the sliding friction stops, and the rotating speed of the driven plate 22 and the rotating speed of the flywheel 21 are synchronous.
In order to enable the fluid to flow and remove heat by flowing through the clutch assembly 20, a fluid inlet 245 is formed in one of the engine flywheel housing 24 and the transmission clutch housing 25, and a fluid outlet 255 is formed in the other of the engine flywheel housing 24 and the transmission clutch housing 25. Such that fluid flowing through the control valve assembly 12 can flow into the clutch assembly 20 from the fluid inlet 245 and out of the fluid outlet 255.
Specifically, the clutch assembly 20 includes opposing first and second ends, with the fluid inlet 245 at the first end and the fluid outlet 255 at the second end. The fluid enters the clutch assembly 20 from the first end, flows through the cavity of the clutch assembly 20 and then flows out from the second end, thereby enlarging the flow area of the fluid in the cavity of the clutch assembly 20 and enhancing the heat dissipation effect.
Further, a temperature sensor 16 is provided between the flywheel 21 and the driven disk 22, specifically, at a friction surface between the flywheel 21 and the driven disk 22, for detecting a friction temperature due to friction slip between the flywheel 21 and the driven disk 22. When the friction temperature is higher than the preset temperature, the fluid enters the clutch assembly 20 through the control valve assembly 12 and flows in a cavity formed by the engine flywheel housing 24 and the transmission clutch housing 25, so that the heat is taken away.
In this embodiment, the fluid inlet 245 is disposed on the flywheel housing 24 of the engine, the fluid outlet 255 is disposed on the clutch housing 25 of the transmission, and the fluid inlet 245 and the fluid outlet 255 are respectively disposed at two opposite ends of the clutch assembly 20, so as to extend the heat dissipation path and improve the heat dissipation effect.
It is understood that in other alternative embodiments, the fluid inlet 245 may also be provided on the transmission clutch housing 25, and the fluid outlet 255 may also be provided on the engine flywheel housing 24, and the specific arrangement position is not limited and depends on the actual requirement.
The clutch heat dissipation method of the clutch heat dissipation system 100 provided by the embodiment of the application is as follows:
determining whether the clutch pedal 26 is depressed controls fluid flow through the clutch assembly 20 to dissipate heat from the clutch assembly 20 when the clutch pedal 26 is depressed.
Further, a real-time temperature of the clutch assembly 20 is obtained, and when the real-time temperature is less than or equal to a preset temperature, fluid is prevented from entering the clutch assembly 20.
That is, the detector 10 detects depression of the clutch pedal 26, and when depression of the clutch pedal 26 is detected, the controller controls the control valve assembly 12 to open to allow fluid to flow through the clutch assembly 20, thereby dissipating heat from the clutch assembly 20.
In addition, a temperature sensor 16 is arranged on the clutch assembly 20, the real-time temperature of the clutch assembly 20 is acquired through the temperature sensor 16 and fed back to the controller 11, the controller 11 compares and judges the received real-time temperature with a preset temperature, and whether the control valve assembly 12 is closed or not is controlled according to the judgment result.
Specifically, when the vehicle is in a starting gear or a gear shift, the clutch is in a clutch-applied stage at the moment when the operator steps on the clutch pedal 26. The detector 10 collects signals of the clutch pedal 26 and feeds the signals back to the controller 11, the controller 11 receives the signals and controls the electromagnetic valve 13 to be opened, so that fluid enters from the fluid inlet 245 on the engine flywheel shell 24, flows through the inner cavity of the clutch assembly 20 and then flows out from the fluid outlet 255 on the transmission clutch shell 25, and the fluid takes away heat in a cavity formed by the engine flywheel shell 24 and the transmission clutch shell 25 in the circulating process.
As the operator continues to step down on the clutch pedal 26, the clutch is completely disengaged, and then the clutch pedal 26 is slowly released. At this time, the driven disk 22 and the flywheel 21, and the driven disk 22 and the clutch cover 23 all generate sliding friction, heat is rapidly generated, and finally the sliding friction stops, and the rotation speeds of the driven disk 22 and the flywheel 21 are synchronized. In this process, air flows in through the fluid inlet 245 and out through the fluid outlet 255, carrying away heat generated by the friction, and rapidly reducing the temperature of the friction face of the driven disk 22 and the interior of the cavity.
At the instant when the operator fully releases the clutch pedal 26, this is in the rear clutch-apply phase. The controller 11 is in communication connection with the temperature sensor 16, the temperature sensor 16 collects temperature signals of the friction surface of the driven disc 22 and feeds the temperature signals back to the controller 11, and the controller 11 compares the received real-time temperature with a preset temperature. If the detected real-time temperature is higher than the preset temperature, the controller 11 controls the electromagnetic valve 13 to be continuously opened, and the fluid is continuously introduced. Until the detected real-time temperature is lower than or equal to the preset temperature, the controller 11 controls the solenoid valve 13 to close, and the fluid stops flowing into the clutch assembly 20. If the real-time temperature detected by the temperature sensor 16 is lower than or equal to the preset temperature when the temperature sensor starts to collect the initial value of the temperature, the controller 11 sends an instruction to control the electromagnetic valve 13 to close immediately, and at this time, the clutch cooling system 100 completes the cooling operation.
It should be understood that, in addition to the above-mentioned way in which the controller 11 controls the electromagnetic valve 13 to open and close for fluid circulation to dissipate heat, in other alternative embodiments, any structure and way may be used as long as the fluid is actively introduced from the outside of the clutch assembly 20 into the cavity formed by the flywheel housing 24 and the clutch housing 25 of the transmission, so that the fluid flows in the cavity and carries away the friction heat of the clutch when flowing out of the cavity, and the embodiments of the present application are not limited thereto.
The clutch cooling system 100, the clutch cooling method and the vehicle provided by the embodiment of the application have the beneficial effects that:
the clutch heat dissipation system 100 can actively dissipate heat of the clutch assembly 20, thereby effectively improving abnormal wear of friction materials of the clutch assembly 20 caused by sliding friction overheating and reduction of torque transmission capacity of the clutch assembly 20 caused by decline of clutch pressing force, and keeping stable friction coefficient of the friction materials of the clutch and clutch torque transmission performance. The conditions such as the unusual wearing and tearing of clutch assembly 20 and vehicle starting shake, clutch that lead to because of the torque transmission ability reduces are further improved and are skidded, effectively reduce clutch assembly 20's fault rate, improve the efficiency of attendance of vehicle, and then promote user's good experience.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
