Embodiment

[0040] The embodiment of the present application provides a vehicle, which includes a clutch cooling system 100 , through which the clutch assembly 20 can be automatically cooled.

[0041] The vehicle in this embodiment refers to a heavy vehicle. Of course, it can be understood that the vehicle may also be other vehicles except the heavy vehicle, for example, a truck, a passenger car, etc., and there is no specific limitation.

[0042] The heavy-duty vehicle is matched with a high-pressure clutch. Because the high-pressure clutch will generate more heat when the vehicle starts or shifts gears, the friction material of the clutch will exceed the critical temperature value and the friction coefficient will decrease; In addition, due to the heavy load of the vehicle and bad operating habits, such as high-end starting, etc., the ineffective slippage of the clutch will be aggravated. If the temperature is too high, the pressing force of the clutch will decline thermally and the torq...

Abstract

The embodiment of the invention provides a heat-dissipating system for a clutch, a heat-dissipating method for the clutch and a vehicle and relates to the technical field of heat dissipation of clutches. The heat-dissipating system for the clutch is used for a clutch assembly provided with a fluid inlet. The heat-dissipating system for the clutch comprises a detector, a controller and a control valve assembly. The control valve assembly is connected to the fluid inlet and is used for controlling opening and closing of the fluid inlet. The controller is in communication connection to the detector and the control valve assembly. The detector is connected to a clutch pedal and is used for detecting whether the clutch pedal is pressed downward or not. When the detector detects that the clutchpedal is pressed downward, the controller controls the control valve assembly to open, so that a fluid flows to the clutch assembly through the fluid inlet. The heat-dissipating method comprises the steps of judging whether the clutch pedal is pressed downward or not; and controlling the fluid to flow through the clutch assembly when the clutch pedal is pressed downward. A purpose of active heat dissipation of the clutch assembly is achieved by means of the heat-dissipating system for the clutch, conditions such as starting shake of the vehicle and slip of the clutch are improved, the failurerate of the clutch assembly is reduced, and the user experience is enhanced.

Description

technical field [0001] The invention relates to the technical field of clutch heat dissipation, in particular to a clutch heat dissipation system, a clutch heat dissipation method and a vehicle. Background technique [0002] With the development of heavy-duty vehicles towards high-horsepower, the clutches with large pressing force matched with high-horsepower engines are also applied thereupon. [0003] The existing clutch with large pressing force is prone to abnormality when the vehicle is started, which affects the user experience. Contents of the invention [0004] The purpose of the present invention includes, for example, providing a clutch heat dissipation system, a clutch heat dissipation method and a vehicle, which can dissipate heat from the clutch assembly through the clutch heat dissipation system, alleviate the abnormality of the clutch assembly caused by overheating due to friction, and improve user experience. [0005] Embodiments of the present invention c...
