Description

Technical Field

[0001] This invention relates to the field of silicone oil clutch fan technology for engineering machinery, and particularly to a silicone oil clutch fan anti-disengagement control method, system, storage medium, and engineering machinery. Background Technology

[0002] Silicone oil clutch fans, widely used in construction machinery, cleverly employ bolt connections to ensure the stability and safety of the fan assembly. This connection method not only requires the bolts to meet certain standards in terms of material and strength but also pays special attention to the direction of the thread. Typically, the thread direction of a silicone oil clutch fan is opposite to the rotation direction of the engine drive wheel. This design has profound implications: when the engine drive wheel rotates, the resulting rotational force attempts to loosen the bolts, but due to the clever arrangement of the thread direction, this loosening tendency is actually transformed into a tightening force, thus greatly reducing the risk of the fan falling off during use.

[0003] However, based on the ingenious reverse bolt connection design described above, the control logic of the silicone oil clutch becomes another issue that requires attention. In existing control systems, the engagement and disengagement of the silicone oil clutch fan (the engagement and disengagement between the silicone oil clutch and the fan) is often controlled by the vehicle controller. This control method achieves a certain degree of automated management of the silicone oil clutch fan, but unfortunately, it does not fully consider the operating status of the entire machine and the fan. Especially when the entire machine is stopped, if the silicone oil clutch is still engaged, the impact force generated by the fan's rotational inertia can become a significant problem. This impact force not only causes wear on the silicone oil clutch itself, but more importantly, it also exerts a huge impact force on the bolts connecting the fan. Over time, this repeated impact may cause the bolts to gradually loosen, even reaching the critical point of falling off.

[0004] If the bolts loosen to the point that they can no longer withstand the force generated by the fan's rotation, the fan may detach. This not only causes the construction machinery to stop operating but can also trigger a series of safety issues. A detached fan could injure surrounding equipment and personnel, causing serious economic losses and personal injury. Summary of the Invention

[0005] The purpose of this invention is to provide a method, system, storage medium, and engineering machinery for preventing the silicone oil clutch fan from falling off, which can prevent the silicone oil clutch fan connection threads from loosening due to the fan running at high speed and then immediately stopping when the silicone oil clutch fan is engaged, thus preventing the fan from falling off.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] In a first aspect, the present invention provides a method for preventing the disengagement of a silicone oil clutch fan, comprising:

[0008] Acquire the shutdown request signal, as well as the real-time silicone oil clutch fan speed and engine speed;

[0009] Determine the type of the acquired shutdown request signal, wherein the shutdown request signal is either a key switch signal or an emergency shutdown request signal;

[0010] When the shutdown request signal is an emergency shutdown request signal, a shutdown command is sent directly to the engine;

[0011] When the shutdown request signal is a key switch signal, a first control command and a second control command are sent to the engine and the silicone oil clutch fan respectively; the first control command is for the engine to enter low idle mode; the second control command is for the silicone oil clutch fan to disengage.

[0012] After the engine enters low idle mode and the silicone oil clutch fan disengages, the fan speed is determined to be less than a threshold based on the fan speed of the silicone oil clutch fan and the engine speed. The threshold is equal to the product of the coupling rate of the silicone oil clutch after disengagement and the engine speed.

[0013] When the fan speed is less than the threshold, a stop command is sent to the engine; when the fan speed is not less than the threshold, the timer is started. If the timer shows a time greater than the preset time, a stop command is sent to the engine.

[0014] Optionally, when the stop request signal is a key switch signal, the current throttle gear is determined. If the current throttle gear is not the lowest gear, a first reminder signal is sent to the display device. The first reminder signal is used to remind the operator to adjust the throttle gear to the lowest gear.

[0015] Optionally, when the timer displays a time longer than a preset time, a second reminder signal is sent to the display device. The second reminder signal is used to remind the operator that the silicone oil clutch fan is malfunctioning.

[0016] Optionally, the emergency stop request signal includes: multiple triggering of the key switch signal within a specified time and a separate emergency stop signal.

[0017] In a second aspect, the present invention provides a silicone oil clutch fan anti-disengagement control system, comprising:

[0018] The main unit controller, and the data acquisition module, silicone oil clutch fan and engine connected to the main unit controller respectively;

[0019] The overall controller is used to implement the silicone oil clutch fan anti-disengagement control method as described in any one of claims 1-4;

[0020] The data acquisition module is connected to the silicone oil clutch fan and the engine respectively, and is used to collect the speed of the silicone oil clutch fan and the speed of the engine in real time and transmit them to the whole machine controller.

[0021] The silicone oil clutch fan includes a silicone oil clutch and a fan, and is used to receive a first control command to perform a disengagement operation between the silicone oil clutch and the fan.

[0022] The engine is used to receive a second control command to enter idle mode and to receive a stop command to perform a stop operation.

[0023] Optionally, the overall controller includes:

[0024] The acquisition module is used to acquire the shutdown request signal, as well as the real-time speed of the silicone oil clutch fan and the engine speed;

[0025] The type determination module is used to determine the type of the acquired shutdown request signal, wherein the type of the shutdown request signal is a key switch signal and an emergency shutdown request signal;

[0026] The emergency processing module is used to directly send a shutdown command to the engine when the shutdown request signal is an emergency shutdown request signal;

[0027] A general processing module includes a first processing unit, a comparison unit, and a second processing unit;

[0028] The first processing unit is configured to send a first control command and a second control command to the engine and the silicone oil clutch fan respectively when the shutdown request signal is a key switch signal; the first control command is for the engine to enter a low idle speed mode; the second control command is for the silicone oil clutch fan to disengage.

[0029] The comparison unit is used to determine whether the fan speed is less than a threshold based on the speed of the silicone oil clutch fan and the engine speed after the engine enters low idle mode and the silicone oil clutch fan disengages. The threshold is equal to the product of the coupling rate of the silicone oil clutch and the engine speed after disengagement.

[0030] The second processing unit is used to send a stop command to the engine when the fan speed is less than the threshold; when the fan speed is not less than the threshold, it controls the timer to start counting; if the timer displays a time greater than the preset time, it sends a stop command to the engine.

[0031] Optionally, the overall controller further includes a gear position determination unit and a time determination unit. The gear position determination unit is used to determine the current throttle gear when the stop request signal is a key switch signal. If the current throttle gear is not the lowest gear, it sends a first reminder signal to the display device. The time determination unit is used to send a second reminder signal to the display device when the time displayed by the timer is greater than a preset time.

[0032] Optionally, the system further includes a display device for displaying information based on a first or second reminder signal sent by the holographic controller.

[0033] Thirdly, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the silicone oil clutch fan anti-disengagement control method as described in the first aspect.

[0034] Fourthly, an engineering machinery, characterized in that it includes a silicone oil clutch fan anti-disengagement control system as described in the second aspect.

[0035] Compared with the prior art, the beneficial effects achieved by the present invention are as follows:

[0036] This invention provides a method, system, storage medium, and engineering machinery for preventing the silicone oil clutch fan from disengaging. The control method, upon receiving a stop request signal, first determines the type of the stop request signal. If it is an emergency stop request signal, a stop command is directly sent to avoid serious problems with the entire machine due to failure to stop immediately in case of an emergency. If it is a normal stop request signal, i.e., a key switch signal, a comprehensive judgment is made based on the overall machine status (engine and fan speeds). Based on the judgment result, a control command is sent to execute the stop operation to prevent the bolts between the silicone oil clutch and the fan from coming loose due to high-speed fan shutdown, thus preventing the fan from disengaging. The judgment result includes either the fan speed being below a threshold or the fan speed being above a threshold for a certain period of time.

[0037] This invention provides a method, system, storage medium, and engineering machinery for preventing the disengagement of a silicone oil clutch fan. The method can also determine the current throttle gear. If the current throttle gear is not the lowest gear, a first reminder signal of "the throttle gear should be at its lowest when the machine is stopped" is sent to the display device. This helps to reduce fuel consumption, extend the service life of the engine and transmission, and improve the safety of the whole machine.

[0038] This invention provides a method, system, storage medium, and engineering machinery for preventing the silicone oil clutch fan from disengaging. The method can also send a second reminder signal indicating that the silicone oil clutch fan is faulty to the display device when the timer displays a time longer than a preset time, reminding the operator to perform maintenance and improving the overall safety of the machine.

[0044] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0045] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure. Any specific values ​​in all examples shown and discussed herein should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0046] Example 1

[0047] refer to Figure 1 This invention provides a method for preventing the disengagement of a silicone oil clutch fan, comprising the following steps:

[0048] Data Acquisition: Acquire the shutdown request signal, as well as the real-time silicone oil clutch fan speed and engine speed;

[0049] Type determination: Determine the type of the acquired shutdown request signal, wherein the type of the shutdown request signal is key switch signal and emergency shutdown request signal;

[0050] Emergency handling: When the shutdown request signal is an emergency shutdown request signal, a shutdown command is sent directly to the engine;

[0051] Normal processing: When the stop request signal is a key switch signal, a first control command and a second control command are sent to the engine and the silicone oil clutch fan respectively; the first control command is for the engine to enter low idle mode; the second control command is for the silicone oil clutch fan to disengage.

[0052] After the engine enters low idle mode and the silicone oil clutch fan disengages, the fan speed is determined to be less than a threshold based on the fan speed of the silicone oil clutch fan and the engine speed. The threshold is equal to the product of the coupling rate k of the silicone oil clutch after disengagement and the engine speed.

[0053] When the fan speed is less than the threshold, a stop command is sent to the engine; when the fan speed is not less than the threshold, the timer is started. If the timer shows a time greater than the preset time T, a stop command is sent to the engine.

[0054] Specifically, emergency stop request signals include: multiple key switch triggering signals within a specified time and a separate emergency stop signal.

[0055] Specifically, the preset time T is the longest time for the clutch to disengage and reach k*input speed at the specified input speed calibrated on the test bench, which is determined based on parameters such as engine coolant temperature, hydraulic oil temperature, fan speed, and silicone oil clutch status.

[0056] Specifically, the coupling rate k of the silicone oil clutch should theoretically be zero after disengagement, but in practical applications, it may be affected by various factors and have a slight value. The specific coupling rate value needs to be measured and evaluated based on the clutch's specific model, structure, and operating conditions.

[0057] Specifically, the engine enters low idle mode based on the engine controller ECM receiving the first control command via the SAE J1939 bus, which controls the engine to enter low idle mode.

[0058] Specifically, the disengagement operation of the silicone oil clutch fan is based on the silicone oil clutch fan receiving a second control command from the I / O line. The internal temperature sensor (bimetallic strip) of the silicone oil clutch fan deforms according to temperature changes. When the temperature of the air flowing through the radiator rises, the bimetallic strip deforms due to heat, and this deformation is converted into mechanical force, thereby controlling the disengagement or engagement of the fan. Since the silicone oil clutch fan itself and the disengagement operation are not the inventive point of this invention, they will not be described in detail here.

[0059] In this embodiment of the invention, after obtaining a shutdown request signal, the type of the shutdown request signal is first determined. If it is an emergency shutdown request signal, a shutdown command is sent directly to avoid serious problems to the whole machine due to failure to shut down immediately in case of an accident. If it is a normal shutdown request signal, i.e., a key switch signal, the overall machine status (engine and fan speed) is considered for comprehensive judgment. Based on the judgment result, a control command is sent to execute the shutdown operation to avoid the situation where the bolt between the silicone oil clutch and the fan falls off due to high-speed fan shutdown, which could lead to the fan falling off.

[0060] Example 2

[0061] refer to Figure 2 This invention provides a method for preventing the disengagement of a silicone oil clutch fan, comprising the following steps:

[0062] Data Acquisition: Acquire the shutdown request signal, as well as the real-time silicone oil clutch fan speed and engine speed;

[0063] Type determination: Determine the type of the acquired shutdown request signal, wherein the type of the shutdown request signal is key switch signal and emergency shutdown request signal;

[0064] Emergency handling: When the shutdown request signal is an emergency shutdown request signal, a shutdown command is sent directly to the engine;

[0065] Normal processing: When the stop request signal is a key switch signal, the current throttle gear is judged. If the current throttle gear is not the lowest gear, a first reminder signal is sent to the display device. The first reminder signal is used to remind the operator to adjust the throttle gear to the lowest gear.

[0066] A first control command and a second control command are sent to the engine and the silicone oil clutch fan, respectively; the first control command is for the engine to enter a low idle speed mode; the second control command is for the silicone oil clutch fan to disengage.

[0067] After the engine enters low idle mode and the silicone oil clutch fan disengages, the fan speed is determined to be less than a threshold based on the fan speed of the silicone oil clutch fan and the engine speed. The threshold is equal to the product of the coupling rate k of the silicone oil clutch after disengagement and the engine speed.

[0068] When the fan speed is less than the threshold, a stop command is sent to the engine; when the fan speed is not less than the threshold, the timer is started. If the timer shows a time greater than the preset time T, a second reminder signal is sent to the display device. The second reminder signal is used to remind the operator that there is a fault in the silicone oil clutch fan and to send a stop command to the engine.

[0069] Example 2 introduces a silicone oil clutch fan anti-disengagement control method, which adds two reminder signal sending and display modules to the basis of Example 1. The first reminder signal is sent to the display device if the current throttle gear is not the lowest gear and the current throttle gear is not the lowest gear. The second reminder signal is sent to the display device if the timer time exceeds the preset time and the silicone oil clutch fan malfunctions. This reminds the operator to perform maintenance and improves the safety of the whole machine.

[0076] The engine is used to receive second control commands to enter idle mode and to receive shutdown commands to perform shutdown operations.

[0077] Specifically, the system also includes a display device (screen monitor) for displaying information based on a first or second reminder signal sent by the overall controller.

[0079] The acquisition module is connected to the data acquisition module and is used to acquire the shutdown request signal, as well as the real-time speed of the silicone oil clutch fan and the engine speed.

[0080] The type determination module is connected to the acquisition module and is used to determine the type of the acquired shutdown request signal. The type of the shutdown request signal is a key switch signal and an emergency shutdown request signal.

[0081] The emergency handling module is connected to the type judgment module and is used to directly send a shutdown command to the engine when the shutdown request signal is an emergency shutdown request signal;

[0082] The general processing module is connected to the type judgment module, and includes a first processing unit, a comparison unit and a second processing unit connected in sequence.

[0083] The first processing unit is configured to send a first control command and a second control command to the engine and the silicone oil clutch fan respectively when the shutdown request signal is a key switch signal; the first control command is for the engine to enter a low idle speed mode; the second control command is for the silicone oil clutch fan to disengage.

[0084] The comparison unit is used to determine whether the fan speed is less than a threshold based on the speed of the silicone oil clutch fan and the engine speed after the engine enters low idle mode and the silicone oil clutch fan disengages. The threshold is equal to the product of the coupling rate of the silicone oil clutch and the engine speed after disengagement.

[0085] The second processing unit is used to send a stop command to the engine when the fan speed is less than the threshold; when the fan speed is not less than the threshold, it controls the timer to start counting; if the timer displays a time greater than the preset time, it sends a stop command to the engine.

The gear position determination unit can be set between the general processing module and the type determination module. When the stop request signal is a key switch signal, it determines the current throttle gear. If the current throttle gear is not the lowest gear, it sends a first reminder signal to the display device. The time determination unit can be set after the second processing unit. When the time displayed by the timer is greater than a preset time, it sends a second reminder signal to the display device.
