Technical Field
[0001] This invention relates to the field of conventional high-speed maglev vehicle technology, and particularly to an air spring air supply control device and a high-speed maglev vehicle. Background Technology
[0002] Currently, in the air spring air supply system of conventional high-speed maglev vehicles, when the suspension system malfunctions, the gas inside the air spring cannot be vented, thus causing the vehicle to malfunction.
[0003] Therefore, when the suspension system of a conventional high-speed maglev vehicle malfunctions, how to vent the gas in the air spring to ensure the normal operation of the vehicle is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] In view of this, the purpose of the present invention is to provide an air spring air supply control device that can exhaust the gas in the air spring when the suspension system of a conventional high-speed maglev vehicle malfunctions, thereby ensuring the normal operation of the vehicle.
[0005] Another object of the present invention is to provide a high-speed maglev vehicle.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An air spring air supply control device includes an air inlet pipe, a connecting pipe, a first exhaust pipe, a second exhaust pipe, a third exhaust pipe, a first solenoid valve, a second solenoid valve, a third solenoid valve, and a controller.
[0008] The first solenoid valve is disposed on the connecting pipe, the second solenoid valve is disposed on the second exhaust pipe, the third solenoid valve can connect the connecting pipe and the second exhaust pipe, and the third solenoid valve can connect the first exhaust pipe and the second exhaust pipe. The third exhaust pipe is disposed between the second solenoid valve and the third solenoid valve and is connected to the second exhaust pipe.
[0009] The first solenoid valve, the second solenoid valve, and the third solenoid valve are all electrically connected to the controller.
[0010] Preferably, it further includes a first check valve and a second throttle valve disposed on the first exhaust pipe, and a second check valve and a third throttle valve disposed on the second exhaust pipe;
[0011] Both the second throttle valve and the third throttle valve are electrically connected to the controller.
[0012] Preferably, it further includes a first pressure switch disposed on the air intake pipe for detecting a first pressure value of the main air supply air path, and the first pressure switch is electrically connected to the controller.
[0013] Preferably, it further includes a first throttle valve disposed on the intake pipe, and the first throttle valve is electrically connected to the controller.
[0014] Preferably, it also includes a second pressure switch disposed on the third exhaust pipe for detecting the second pressure value of the air spring.
[0015] Preferably, it also includes a third pressure switch disposed on the third exhaust pipe for detecting the third pressure value of the air spring.

Detailed Implementation
[0025] In view of this, the core of the present invention is to provide an air spring air supply control device, which can exhaust the gas in the air spring when the suspension system of a conventional high-speed maglev vehicle malfunctions, thereby ensuring the normal operation of the vehicle.
[0026] Another core aspect of this invention is to provide a high-speed maglev vehicle.
[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Please refer to Figure 1 The air spring air supply control device disclosed in this embodiment of the invention includes an air intake pipe 100, a connecting pipe 200, a first exhaust pipe 300, a second exhaust pipe 400, a third exhaust pipe 600, a first solenoid valve 201, a second solenoid valve 401, a third solenoid valve 500, and a controller. The first solenoid valve 201 is disposed on the connecting pipe 200, the second solenoid valve 401 is disposed on the second exhaust pipe 400, the third solenoid valve 500 can connect the connecting pipe 200 and the second exhaust pipe 400, and the third solenoid valve 500 can connect the first exhaust pipe 300 and the second exhaust pipe 400. The third exhaust pipe 600 is disposed between the second solenoid valve 401 and the third solenoid valve 500 and is connected to the second exhaust pipe 400. The first solenoid valve 201, the second solenoid valve 401, and the third solenoid valve 500 are all electrically connected to the controller.
[0029] During the operation of a conventional maglev vehicle, when a malfunction occurs in the levitation system, the controller de-energizes the first solenoid valve 201 while simultaneously energizing the second solenoid valve 401 and the third solenoid valve 500. At this time, the intake pipe 100 is disconnected from the connecting pipe 200, and the first exhaust pipe 300 and the second exhaust pipe 400 are connected through the third solenoid valve 500. The gas in the air spring enters the first exhaust pipe 300 and the second exhaust pipe 400 through the third exhaust pipe 600, and is then discharged through the first exhaust pipe 300 and the second exhaust pipe 400. Compared with existing technologies, when a malfunction occurs in the levitation system of a conventional high-speed maglev vehicle, the gas in the air spring can be vented through the aforementioned air spring air supply control device, thereby ensuring the normal operation of the vehicle.
[0030] To ensure that the gas inside the air spring can be smoothly discharged from the first exhaust pipe 300 and the second exhaust pipe 400, the air spring air supply control device disclosed in the embodiments of the present invention further includes a first one-way valve 301 and a second throttle valve 302 disposed on the first exhaust pipe 300, and a second one-way valve 402 and a third throttle valve 403 disposed on the second exhaust pipe 400, wherein the second throttle valve 302 and the third throttle valve 403 are both electrically connected to the controller.
[0031] The first check valve 301 and the second check valve 402 can prevent gas from flowing back into the first exhaust pipe 300 and the second exhaust pipe 400. The second throttle valve 302 can effectively regulate the gas flow rate of the first exhaust pipe 300, and the third throttle valve 403 can effectively regulate the gas flow rate of the second exhaust pipe 400.
[0032] In order to detect the gas pressure of the intake pipe 100, the air spring air supply control device disclosed in the embodiment of the present invention further includes a first pressure switch 101 disposed on the intake pipe 100 for detecting the first pressure value of the total air supply air path, and the first pressure switch 101 is electrically connected to the controller.
[0033] The first pressure switch 101 detects the first pressure value of the main air supply circuit and compares the first pressure value with the first preset pressure value. When the first pressure value is within the range of the first preset pressure value, the controller controls the first solenoid valve 201 to be energized, and the connecting pipe 200 is connected to ensure normal air supply. When the first pressure value is outside the range of the first preset pressure value, the controller controls the first solenoid valve 201 to be de-energized, and the connecting pipe 200 is disconnected to allow directional air leakage in the air spring.
[0034] In order to control the flow rate of gas in the intake pipe 100, the air spring air supply control device disclosed in the embodiment of the present invention further includes a first throttle valve 101 disposed on the intake pipe 100, and the first throttle valve 101 is electrically connected to the controller. The controller controls the first throttle valve 101 to adjust the flow rate of gas.
[0035] In order to detect the gas pressure of the air spring, the air spring air supply control device disclosed in the embodiments of the present invention further includes a second pressure switch 601 disposed on the third exhaust pipe 600 for detecting the second pressure value of the air spring, and a third pressure switch 602 for detecting the third pressure value of the air spring.
[0036] It should be noted that the second preset pressure value set by the second pressure switch 601 is different from the third preset pressure value set by the third pressure switch 602, and they are set for different working conditions respectively.
[0037] During the operation of the high-speed maglev vehicle, the second pressure switch 601 detects the second pressure value of the air spring and compares it with a second preset pressure value. When the second pressure value is within the second preset pressure value range, the controller energizes the first solenoid valve 201, connecting the pipe 200 to ensure normal air supply and exhaust. When the second pressure value is outside the second preset pressure value range, the controller de-energizes the first solenoid valve 201, disconnecting the pipe 200 to prevent air spring leakage from causing a pressure collapse in the main air supply pipe.
[0038] When the suspension system malfunctions and gas needs to be discharged to reach the third preset pressure value, the third pressure value of the third exhaust pipe 600 can be detected by the third pressure switch 602. When the third pressure switch 602 detects that the third pressure value of the third exhaust pipe 600 has reached the third preset pressure value, it can control the venting to stop.
[0039] The embodiments of the present invention do not limit the specific structure of the first solenoid valve 201, the second solenoid valve 401 and the third solenoid valve 500. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.
[0040] As a preferred embodiment, the first solenoid valve 201 and the second solenoid valve 401 disclosed in the embodiments of the present invention are preferably two-position two-way solenoid valves, and the third solenoid valve 500 is preferably a two-position five-way solenoid valve.
[0041] It should be noted that during the operation of the high-speed maglev vehicle, when the air spring is being inflated, the controller energizes the first solenoid valve 201, at which point the connecting pipe 200 is in a connected state. At the same time, the controller de-energizes the second solenoid valve 401 and the third solenoid valve 500, at which point the connecting pipe 200 is connected to the third exhaust pipe 600. Gas enters from the air inlet, passes through the air inlet pipe 100 and the connecting pipe 200 in sequence, and enters the third exhaust pipe 600, and then enters the air spring from the third exhaust pipe 600.
[0042] To facilitate maintenance of the air spring air supply control device, the air spring air supply control device disclosed in this embodiment of the invention is further provided with a test connector 700 on the third exhaust pipe 600. With this configuration, when maintenance of the air spring air supply control device is required, air can be injected from the test connector 700 to test the fault condition of the air spring air supply control device.
