[0002] At present, with the rapid development of rail technology, the demand for rail engineering vehicles for maintenance is also increasing. Rail engineering vehicles are usually equipped with operating mechanisms, the working range of which usually exceeds the vehicle body, and the operating mechanism has a certain load-bearing capacity, which can easily cause the center of gravity of the rail engineering vehicle to shift, resulting in different deformation of the rubber spring structure on both sides of the rail engineering vehicle, causing the vehicle to tilt or overturn.

[0035] Figures 3 to 5 Schematic diagram of a vehicle suspension locking method provided in an embodiment of the present application. Any of the following methods can be executed in a suspension system, or in a server or terminal device connected to the suspension system. In the embodiment of the present application, the suspension system is used as the execution subject to explain the solution.

[0036] Based on the structure of the above suspension system, such as Figure 3 As shown, an embodiment of the present application provides a vehicle suspension locking method, comprising:

[0037] S31, the system detects vehicle status information.

[0038] S32, the system controls the vehicle jacking cylinder and / or the axle jacking cylinder to extend or retract according to the vehicle status information.

[0039] In the embodiment of the present application, the jacking cylinder and / or the jacking shaft cylinder in this step can be any one or more jacking cylinders and / or jacking shaft cylinders of the bogies arranged on the car body. For example, the bogie at the front of the car body and the bogie at the rear of the car body, or the bogie at the front of the car body, the bogie in the middle of the car body and the bogie at the rear of the car body, etc. The jacking cylinder and / or the jacking shaft cylinder of each bogie can be controlled synchronously or separately.

[0040] S33, the system locks the jacking cylinder and the jacking cylinder.

[0041] The vehicle suspension locking method provided in the embodiment of the present application is used to detect vehicle status information, and according to the vehicle status information, the jacking cylinder and / or the jacking shaft cylinder are controlled to extend or retract, and finally the jacking cylinder and the jacking shaft cylinder are locked. By controlling the jacking cylinder and / or the jacking shaft cylinder to extend or retract based on the vehicle status information, the status of the jacking cylinder and / or the jacking shaft cylinder can be matched with the vehicle status, so that the suspension system can cope with the local eccentric load caused by the different forces and load-bearing directions of the operating device in different operating states, and avoid the vehicle from tilting or overturning.

[0042] Based on the structure of the above suspension system, such as Figure 4 As shown, the embodiment of the present application provides another vehicle suspension locking method, comprising:

[0043] S31, the system detects vehicle status information.

[0044] S41, the system determines the operating status of the vehicle according to the vehicle status information.

[0045] S42, the system controls the jacking cylinder and / or the jacking cylinder to extend or retract according to the operating status.

[0046] S33, the system locks the jacking cylinder and the jacking cylinder.

[0047] By using the vehicle suspension locking method provided in the embodiment of the present application, the operating state of the vehicle is determined according to the vehicle state information, and the jacking cylinder and / or the jacking shaft cylinder are controlled to extend or retract according to the operating state. By detecting the vehicle state information and determining the operating state, the suspension system can adjust the state of the jacking cylinder and the jacking shaft cylinder according to specific operating requirements. This enables the vehicle to adapt to different operating states such as stationary, forward and backward, and improves the flexibility and efficiency of the operation.

[0048] Optionally, the system determines the operating state of the vehicle based on the vehicle state information, and the system determines whether the working mode is the operating mode; when the working mode is the operating mode, the system determines the operating state of the vehicle based on the vehicle gear information.

[0049] When the working mode is the operation mode, the system determines the vehicle's operating status based on the vehicle's gear information. The vehicle's gear information is the key to determining the vehicle's operating direction. The system determines the vehicle's operating status based on the gear information (neutral, forward gear, reverse gear), thereby controlling the corresponding jacking cylinder and jacking shaft cylinder to extend or retract.

[0050] Optionally, the system determines the operating status of the vehicle based on the vehicle gear information, including: when the vehicle gear is neutral, the system determines that the vehicle is in a stationary operating state; when the vehicle gear is a forward gear, the system determines that the vehicle is in a forward operating state; when the vehicle gear is a reverse gear, the system determines that the vehicle is in a reverse operating state.

[0051] Among them, high-precision sensors can be used to monitor the gear status. This can accurately detect gear changes and convert these changes into electrical signals and send them to the suspension system. The processor or controller inside the suspension system can quickly process the received high-precision sensor signals and identify and respond to gear changes in real time.

[0052] In this way, when the vehicle gear is in neutral, the system determines that the vehicle is in a stationary operating state. When the vehicle gear is in forward gear, the system determines that the vehicle is in forward operating state. When the vehicle gear is in reverse gear, the system determines that the vehicle is in reverse operating state. The gear information of the vehicle directly reflects the vehicle's movement intention and operating direction, and is the key basis for judging the operating state. By identifying the gear information of the vehicle, the system can determine the operating direction of the vehicle, whether it is stationary, forward or reverse, thereby achieving precise control of the operating direction.

[0053] Optionally, after the system determines whether the working mode is the operation mode, it further includes: when the working mode is not the operation mode, the system controls the jacking cylinder and the jacking shaft cylinder to retract.

[0054] In this way, when the working mode is non-operating mode, the system controls the jacking cylinder and the jacking cylinder to retract. In the non-operating mode, by controlling the jacking cylinder and the jacking cylinder to retract, it is possible to avoid operating in an inappropriate state and reduce potential risks.

[0055] Optionally, when the working mode is not the operation mode, after the system controls the jacking cylinder and the jacking shaft cylinder to retract, it also includes: the system detects whether the jacking cylinder returns to its original position; when the jacking cylinder returns to its original position, the system detects whether the hydraulic pressure of the rodless chamber of the jacking shaft cylinder is less than the set unlocking pressure value; when the hydraulic pressure of the rodless chamber of the jacking shaft cylinder is less than the set unlocking pressure value, the system locks the jacking cylinder and the jacking shaft cylinder.

[0056] In this way, the system detects whether the jacking cylinder has returned to its original position, ensuring that the jacking cylinder is fully retracted to its initial position when not in operation mode, preventing the jacking cylinder from being locked when not fully retracted, avoiding damage to the jacking cylinder or its connected parts, or instability when the vehicle is moving. When the jacking cylinder returns to its original position, the system detects whether the hydraulic pressure of the rodless chamber of the jacking cylinder is less than the set unlocking pressure value. By detecting the hydraulic pressure of the rodless chamber of the jacking cylinder, the system can determine whether the jacking cylinder has been fully retracted and the pressure has dropped to a safe range, providing protection for the locking operation.

[0057] Based on the structure of the above suspension system, such as Figure 5 As shown, the embodiment of the present application provides another vehicle suspension locking method, comprising:

[0058] S31, the system detects vehicle status information.

[0059] S41, the system determines the operating status of the vehicle according to the vehicle status information.

[0060] S51, when the vehicle is in a stationary working state, the system controls the first jacking cylinder, the vehicle jacking cylinder and the second jacking cylinder to extend.

[0061] S52, when the vehicle is in the forward operation state, the system controls the vehicle jacking cylinder and the second axle jacking cylinder to extend, and controls the first axle jacking cylinder to retract.

[0062] S53, when the vehicle is in the backward operation state, the system controls the first jacking cylinder and the vehicle jacking cylinder to extend, and controls the second jacking cylinder to retract.

[0063] S33, the system locks the jacking cylinder and the jacking cylinder.

[0064] Using the vehicle suspension locking method provided by the embodiment of the present application, when the vehicle is in stationary operation, the vehicle needs maximum stability and support force to prevent tilting or offset caused by the operating load. Therefore, in the stationary operating state, the system controls the first jacking cylinder, the jacking cylinder and the second jacking cylinder to extend to provide comprehensive support for the vehicle. Forward operation may require more front support to resist the backward tilt caused by the operating load, and retracting the first jacking cylinder can meet the working requirements of the bogie guide shaft. Therefore, in the forward operating state, the system controls the jacking cylinder and the second jacking cylinder to extend, and controls the first jacking cylinder to retract, optimizing the front support and balance of the vehicle. Reverse operation may require more rear support to resist the forward tilt caused by the operating load, and retracting the second jacking cylinder can reduce the rear load and maintain the stability of the vehicle. Therefore, in the backward operating state, the system controls the first jacking cylinder and the jacking cylinder to extend, and controls the second jacking cylinder to retract, optimizing the rear support and balance of the vehicle. By accurately controlling the cylinder state, the vehicle can better adapt to the different load and stability requirements during stationary, forward and backward operations.

[0065] Optionally, the system locks the jacking cylinder and the jacking shaft cylinder, including: the system determines whether the hydraulic pressure of the rodless chamber of the retracted jacking cylinder and / or the jacking shaft cylinder is less than the set unlocking pressure value; when the hydraulic pressure of the rodless chamber of the retracted jacking shaft cylinder is less than the set unlocking pressure value and is in the working mode, the system determines whether the hydraulic pump outlet pressure is greater than the set locking pressure value; when the hydraulic pump outlet pressure is greater than the set locking pressure value, the system locks the jacking cylinder and the jacking shaft cylinder. In another embodiment, when the hydraulic pressure of the rodless chamber of the retracted jacking shaft cylinder is less than the set unlocking pressure value and is in the non-working mode, it is determined whether the in-situ travel switch detection is in place; when the in-situ travel switch detection is in place, the jacking cylinder and the jacking shaft cylinder are locked.

[0066] Among them, the hydraulic cylinder is composed of a cylinder body, a piston and a piston rod. The piston divides the inside of the cylinder into two parts, namely, a rod chamber and a rodless chamber. The rodless chamber is located opposite the piston, that is, the cylinder space on the side where the piston rod extends. In the embodiment of the present application, the system determines whether the cylinder has been retracted to its original position by monitoring the hydraulic pressure of the rodless chamber, thereby determining whether to lock the cylinder. In actual application, when the vehicle is in a stationary operating state, since both the jacking cylinder and the jacking shaft cylinder are extended, the system does not determine whether the hydraulic pressure of the retracted jacking cylinder and / or the rodless chamber of the jacking shaft cylinder is less than the set unlocking pressure value. When the vehicle is in a forward operating state, since the system controls the jacking cylinder and the second jacking shaft cylinder to extend and controls the first jacking shaft cylinder to retract, the system only determines whether the hydraulic pressure of the rodless chamber of the first jacking shaft cylinder is less than the set unlocking pressure value. When the vehicle is in the reverse operation state, the system controls the first jacking cylinder and the jacking cylinder to extend, and controls the second jacking cylinder to retract. Therefore, the system only determines whether the hydraulic pressure of the rodless chamber of the second jacking cylinder is less than the set unlocking pressure value.

[0067] Among them, in the embodiment of the present application, the unlocking pressure value is a preset hydraulic pressure threshold value, which is used to control the locking and unlocking operations of the cylinder. If the system detects that the hydraulic pressure of the rodless chamber is less than the unlocking pressure value, it means that the system can proceed to the next locking operation. The set locking pressure is a preset pressure threshold value used to determine whether the cylinder (such as the jacking cylinder and the jacking cylinder) can be safely locked in a specific position. The system monitors the pressure at the outlet of the hydraulic pump. When the pressure at the outlet of the hydraulic pump is greater than the set locking pressure value, it triggers the locking mechanism to lock the cylinder.

[0068] In this way, the system determines whether the hydraulic pressure of the rodless chamber of the retracted jacking cylinder and / or jacking shaft cylinder is less than the set unlocking pressure value to determine whether the jacking cylinder and / or jacking shaft cylinder are in a state that can be safely locked. If the rodless chamber pressure is lower than the unlocking pressure value, it means that the jacking cylinder and / or jacking shaft cylinder have been retracted to an appropriate position, providing a prerequisite for the locking operation. Therefore, when the hydraulic pressure of the rodless chamber of the retracted jacking shaft cylinder is less than the set unlocking pressure value, it means that the rodless chamber of the retracted jacking shaft cylinder has been retracted to an appropriate position and can be locked. At this time, the system continues to determine whether the hydraulic pump outlet pressure is greater than the set locking pressure value to ensure that the pressure of the hydraulic system is high enough to safely lock the hydraulic cylinder. When the hydraulic pump outlet pressure is greater than the set locking pressure value, the system locks the jacking cylinder and jacking shaft cylinder to ensure that the hydraulic cylinder remains in a fixed state during operation, preventing the cylinder position from changing due to hydraulic fluctuations or external load changes, thereby ensuring vehicle stability and operation safety.
