A method, device and equipment for detecting the operating state of an electronically controlled silicon oil clutch

Abstract

The embodiment of the present application discloses a method, device and equipment for detecting the running state of an electronically controlled silicon oil clutch. The electronically controlled silicon oil clutch is connected to a fan. The method includes: obtaining the rotational speed of the fan and the rotational speed of the engine periodically; The rotation speed of the fan, the rotation speed of the engine and the transmission ratio determine the periodic state detection parameters, wherein the transmission ratio is the transmission ratio of the fan and the engine; select the target to be satisfied by the determined multiple state detection parameters from a plurality of preset detection conditions A detection condition: determining the running state corresponding to the target detection condition as the running state of the electronically controlled silicon oil clutch. The operating state of the electronically controlled silicone oil clutch can be monitored inside the vehicle without external detection devices, and the operation is simple.

Description

technical field [0001] The present application relates to the technical field of engines, in particular to a method, device and equipment for detecting the operating state of an electronically controlled silicon oil clutch. Background technique [0002] Since the era of electronic control, the temperature requirements of the engine for the coolant have become more and more accurate. As an important part of the engine cooling system, the silicon oil fan clutch has basically become the standard configuration of the current heavy trucks. The electronically controlled silicon oil fan is more and more used in the vehicle cooling system because of its high speed adjustable range, low power consumption and good heat dissipation performance. [0003] In actual use, the electronically controlled silicon oil fan clutch will inevitably have some failures. For example, when the electronically controlled silicon oil fan has silicon oil leakage or other reasons cause the state of the sili...

AI Technical Summary

Problems solved by technology

[0003] In actual use, the electronically controlled silicon oil fan clutch will inevitably have some failures. For example, when the electronically controlled silicon oil fan has silicon oil leakage or other reasons cause the state of the silicon oil clutch to be abnormal, the fan cannot achieve variable speed control.

If the electronically controlled silicon oil fan clutch fails, the speed of the fan cannot be adjusted according to the temperature of the coolant, resulting in a decrease in heat dissipation

If the driver runs the vehicle without knowing the failure of the fan clutch, the engine will boil quickly because the fan cannot achieve variable speed control, and in severe cases, it may even cause the engine to melt; if the silicon oil clutch is stuck, the fan of the silicon oil clutch will become rigid. The fan will increase the fuel consumption of the vehicle

[0004] In related technologies, an external detection device is usually required to detect whether the operating state of the silicone oil clutch is abnormal, which is inconvenient to operate
