Description

Technical Field

[0001] This utility model relates to the field of rail vehicles, and provides a valve group integrated module and a rail vehicle. Background Technology

[0002] With the widespread application of high-speed trains, anti-slip valves and balance valves play a crucial role in train braking and stable operation. However, there are currently some problems with the arrangement of anti-slip valves and balance valves in high-speed trains.

[0003] First, due to the significant differences in the undercarriage space configuration of different vehicle models, the installation positions of the anti-slip valve and the balance valve are not uniform, which brings inconvenience to maintenance and routine upkeep.

[0004] Secondly, anti-slip valves and balance valves are usually arranged according to the air pipeline path, and their locations are relatively scattered, which not only increases the difficulty of maintenance, but also directly affects the stability of vehicle operation.

[0005] Finally, the current installation structure is mostly fixed directly under the crossbeam of the vehicle body. This decentralized arrangement not only increases the design workload for different vehicle models, but also hinders the realization of standardized and modular design concepts. Utility Model Content

[0006] This utility model provides a valve group integration module to achieve the functional integration of anti-slip valve and balance valve, which is highly adaptable and has a reasonable structure.

[0007] This utility model embodiment also provides a rail vehicle.

[0008] This utility model provides a valve assembly integrated module, including: An integrated substrate is formed by brazing multiple stacked metal plates and a sealed internal air passage is formed between the joint surfaces of the metal plates. The integrated substrate is provided with at least one first valve mounting position and one second valve mounting position. An anti-slip valve is installed at the first valve mounting position and is connected to the internal air passage via the integrated substrate; A balancing valve is installed at the second valve mounting position and is connected to the internal air passage via the integrated substrate.

[0009] According to one embodiment of the present invention, grooves are processed on the metal plates of the integrated substrate, and after multiple metal plates are stacked and brazed, the grooves on adjacent metal plates together form the internal air passage.

[0010] According to one embodiment of the present invention, the number of anti-slip valves is two, and the two anti-slip valves and the balance valve are symmetrically distributed on the integrated substrate.

[0011] According to one embodiment of the present invention, the two anti-slip valves include a single-inlet anti-slip valve and a double-inlet anti-slip valve.

[0012] According to one embodiment of the present invention, the integrated substrate has a mounting plane, and the first valve mounting position and the second valve mounting position are both disposed on the mounting plane.

[0013] According to one embodiment of the present invention, the integrated substrate is provided with an externally connected air passage interface and an electrical interface; all the air passage interfaces and the electrical interfaces are arranged in the same direction.

[0014] According to one embodiment of the present invention, both the first valve mounting position and the second valve mounting position are provided with interface through holes that communicate with the internal air passage; the anti-slip valve and the balance valve are respectively sealed and installed at the interface through holes by sealing elements.

[0015] According to one embodiment of the present invention, a pressure sensor and / or test connector are also fixedly mounted on the integrated substrate, and the pressure sensor and / or test connector are connected to the internal air passage.

[0016] According to one embodiment of the present invention, a mounting base is also included, the mounting base including a first mounting portion for fixing to the integrated substrate, a second mounting portion for fixing to a rail vehicle, and a connecting portion for connecting the first mounting portion and the second mounting portion.

[0017] According to one embodiment of the present invention, the connecting part is provided with reinforcing ribs.

[0018] This utility model also provides a rail vehicle, including a car body underframe and the aforementioned valve group integrated module; the valve group integrated module is installed on the car body underframe.

[0019] According to one embodiment of the present invention, the valve group integration module is fixed to the triangular space on one side of the bogie of the car body underframe by a mounting base; the external air circuit interface and electrical interface provided on the integration module are both facing the outside of the rail vehicle.

[0020] According to the valve assembly integrated module provided in the first aspect of this utility model, the integrated substrate adopts a structure design of multiple metal plates stacked and brazed. Compared with the traditional method of connecting the anti-slip valve and the balance valve with independent pipelines, it can directly form a sealed internal air passage inside the substrate, significantly reducing the number of external exposed pipelines. This avoids damage to external pipelines caused by vibration, collision, or environmental corrosion during vehicle operation, while reducing the risk of gas leakage and significantly improving the reliability and stability of air passage transmission. The application of the brazing process ensures a tight connection between the metal plates, further strengthening the airtightness of the internal air passage. This provides a stable gas transmission environment for the normal operation of the anti-slip valve and the balance valve, avoiding inaccurate pressure regulation due to air passage leakage, and ensuring the accuracy of braking and air spring pressure control of the rail vehicle. The setting of the first valve mounting position and the second valve mounting position provides precise installation positioning for the anti-slip valve and the balance valve, avoiding air passage misalignment caused by valve installation position deviation, and improving the convenience and accuracy of valve installation. At the same time, the fixed installation position ensures the overall structural stability of the valve after installation, reducing the impact of vibration on the valve during vehicle operation and extending the service life of the valve. The anti-slip valve and the balance valve are integrated through an integrated base plate, replacing the traditional decentralized arrangement. This significantly simplifies the overall structure, reduces the space occupied by the modules under the rail vehicle, and improves the utilization rate of the under-vehicle space. The integrated structure also facilitates unified inspection and maintenance of the anti-slip valve and the balance valve by the staff, eliminating the need to locate the decentralized components separately, reducing maintenance difficulty and workload, and improving maintenance efficiency.

[0021] According to the second aspect of the present invention, the rail vehicle with valve assembly integrated module is installed in the triangular space of the car body underframe. This fully utilizes the idle space of the car body underframe, avoids the integrated module competing with other undercarriage components for installation space, significantly improves the utilization rate of the undercarriage space of the rail vehicle, and makes the layout of undercarriage equipment more regular, meeting the design requirements of modularization and lightweighting. The mounting base ensures a stable connection between the integrated module and the car body underframe. Even if the rail vehicle experiences vibration or impact during operation, it can prevent the integrated module from shaking, shifting, or falling off, ensuring the installation reliability of the integrated module and extending its service life. At the same time, the adaptability design of the mounting base allows the integrated module to be adapted to the car body underframe structure of different models, eliminating the need to design separate installation structures for different models, reducing the workload of model design, and improving the versatility of the integrated module. The anti-slip valve and balance valve in the integrated module function synergistically through internal air circuits. Single-inlet and dual-inlet anti-slip valves precisely regulate the brake cylinder pressure of each axle of the bogie, effectively preventing wheelset slippage or wheel rubbing. The balance valve promptly adjusts the air spring pressure, ensuring pressure stability during vehicle operation, thereby improving the braking safety and smoothness of the rail vehicle. The air circuit interfaces and electrical interfaces on the integrated base plate face outwards from the vehicle, allowing personnel to easily connect or disconnect pipelines and lines during installation or maintenance without disassembling the car body skirts or other peripheral components. This significantly reduces installation difficulty and maintenance workload, improving construction and maintenance efficiency. Furthermore, the integrated design replaces the traditional dispersed arrangement of anti-slip valves and balance valves, avoiding problems such as complex air circuits and multiple failure points caused by component dispersion, reducing the risk of gas leakage, and improving the operational reliability of the rail vehicle's braking and suspension systems.

[0028] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0029] like Figures 1 to 4 As shown, this utility model provides a valve assembly integrated module, including: The integrated substrate 100 is formed by brazing multiple stacked metal plates and a sealed internal air passage is formed between the joint surfaces of the metal plates. The integrated substrate 100 is provided with at least one first valve mounting position and one second valve mounting position. Anti-slip valve 102 is installed at the first valve mounting position and is connected to the internal air passage via integrated base plate 100; The balancing valve 104 is installed in the second valve mounting position and is connected to the internal air passage via the integrated base plate 100.

[0030] According to the valve assembly integrated module provided in the first aspect embodiment of this utility model, the integrated substrate 100 adopts a structure design of multiple metal plates stacked and brazed. Compared with the traditional method of connecting the anti-slip valve 102 and the balance valve 104 with independent pipelines, it can directly form a sealed internal air passage inside the substrate, which greatly reduces the number of external exposed pipelines and avoids damage to external pipelines caused by vibration, collision or environmental corrosion during vehicle operation. At the same time, it reduces the risk of gas leakage and significantly improves the reliability and stability of air passage transmission. The application of the brazing process ensures a tight connection between the metal plates, further strengthening the airtightness of the internal air passage, providing a stable gas transmission environment for the normal operation of the anti-slip valve 102 and the balance valve 104, avoiding the problem of inaccurate pressure regulation caused by air passage leakage, and ensuring the accuracy of braking and air spring pressure control of the rail vehicle. The setting of the first valve mounting position and the second valve mounting position provides precise installation positioning for the anti-slip valve 102 and the balance valve 104, avoiding the problem of poor air passage connection caused by valve installation position deviation, and improving the convenience and accuracy of valve installation. Meanwhile, the fixed installation position ensures the overall structural stability of the valve after installation, reducing the impact of vibration during vehicle operation and extending the valve's service life. The anti-slip valve 102 and the balancing valve 104 are integrated via an integrated base plate 100, replacing the traditional distributed arrangement. This significantly simplifies the overall structure, reduces the space occupied by the modules under the rail vehicle, and improves the utilization rate of this space. The integrated structure also facilitates unified inspection and maintenance of the anti-slip valve 102 and the balancing valve 104, eliminating the need to locate separately distributed components, reducing maintenance difficulty and workload, and improving maintenance efficiency.

[0031] In addition, the anti-slip valve 102 and the balance valve 104 are directly connected through the internal air passage of the integrated base plate 100, which shortens the air passage distance between the two and the corresponding control components, and can speed up the response speed of pressure regulation. This ensures that the anti-slip valve 102 adjusts the brake cylinder pressure in time to prevent wheel slippage, and the balance valve 104 quickly adjusts the air spring pressure to ensure the smooth operation of the vehicle, thereby improving the operation safety and stability of the rail vehicle.

[0032] Please continue reading Figures 1 to 4 The integrated substrate 100 of the valve assembly module is composed of multiple metal plates, which are stacked sequentially in a preset order. The stacked metal plates are then connected by brazing to form a single integrated structure. The brazing creates a seal between the mating surfaces of the metal plates, forming a sealed internal air passage. This internal air passage ensures stable gas transmission within the integrated substrate 100 without any gas leakage.

[0033] The surface of the integrated substrate 100 is provided with at least one first valve mounting position and one second valve mounting position, wherein the structure of the first valve mounting position is adapted to the installation requirements of the anti-slip valve 102 and is used to provide a stable mounting base for the anti-slip valve 102; the structure of the second valve mounting position is adapted to the installation requirements of the balance valve 104 and is used to provide a stable mounting base for the balance valve 104.

[0034] The anti-slip valve 102 is installed on the first valve mounting position by a suitable fixing method. The air passage interface 108 of the anti-slip valve 102 is precisely aligned with the air passage on the integrated substrate 100 corresponding to the first valve mounting position, thereby connecting with the internal air passage of the integrated substrate 100. This allows the anti-slip valve 102 to receive externally input gas through the internal air passage or output regulated gas to external actuators, thereby realizing the function of regulating the pressure of the rail vehicle brake cylinder.

[0035] The balance valve 104 is installed on the second valve mounting position by a suitable fixing method. The air passage interface 108 of the balance valve 104 is precisely connected to the air passage on the integrated substrate 100 corresponding to the second valve mounting position, thereby communicating with the internal air passage of the integrated substrate 100. This allows the balance valve 104 to receive gas through the internal air passage, regulate the gas pressure, and then deliver it to the air spring of the rail vehicle to ensure the stability of the air spring pressure.

[0036] According to one embodiment of the present invention, grooves 106 are processed on the metal plates of the integrated substrate 100. After multiple metal plates are stacked and brazed, the grooves 106 on adjacent metal plates together form an internal air passage.

[0037] In one embodiment of this invention, each metal plate included in the integrated substrate 100 has a groove 106 processed on its surface. The shape and orientation of the groove 106 are designed according to the gas flow requirements between the anti-slip valve 102 and the balance valve 104. Multiple metal plates with pre-processed grooves 106 are stacked in a preset order to ensure that the grooves 106 on adjacent metal plates can align with each other. The stacked metal plates are then brazed to form a tight and secure connection between adjacent metal plates. After brazing, the grooves 106 on two adjacent metal plates are joined together to form an internal gas passage with a sealed structure. This internal gas passage enables gas transmission between the anti-slip valve 102 and the balance valve 104 without the need for additional external connecting pipes.

[0038] The internal air passage is formed by combining the metal plate groove 106 with a brazing process, avoiding the exposed layout of external pipelines, reducing the risk of damage to pipelines due to collisions and wear, and improving the structural stability of the integrated module. The brazing connection ensures that the internal air passage has good airtightness, effectively preventing gas leakage and ensuring the normal operation of the anti-slip valve 102 and the balance valve 104. At the same time, the groove 106 design can flexibly adapt to different air passage routing requirements without changing the overall structure of the metal plate, improving the versatility of the integrated base plate 100 and reducing the design cost when adapting to different vehicle models.

[0039] According to one embodiment of the present invention, there are two anti-slip valves 102, and the two anti-slip valves 102 and the balance valve 104 are symmetrically distributed on the integrated substrate 100.

[0040] In one embodiment of this utility model, two anti-slip valves 102 are provided. The two anti-slip valves 102 and one balance valve 104 are jointly mounted on the integrated substrate 100, and the three are symmetrically distributed. Specifically, the two anti-slip valves 102 are respectively arranged on both sides of the integrated substrate 100, and the balance valve 104 is arranged in the middle position between the two anti-slip valves 102, with the center line connecting the three forming a symmetrical structure. Both anti-slip valves 102 are fixed to the first valve mounting position of the integrated substrate 100 by bolts, and the balance valve 104 is fixed to the second valve mounting position of the integrated substrate 100 by bolts, ensuring that the mounting positions of the three on the integrated substrate 100 are stable and symmetrical.

[0041] The symmetrical distribution of the two anti-slip valves 102 and the balance valve 104 ensures balanced force distribution across the integrated module, preventing deformation of the integrated substrate 100 or mounting structure due to uneven weight distribution and improving the module's structural reliability. The symmetrical layout also gives the integrated module a neat appearance and facilitates quick identification of the valve positions by operators, reducing the difficulty of positioning during maintenance. Furthermore, the two anti-slip valves 102 on either side control the brake cylinder pressures of different axles of the rail vehicle bogie, while the middle balance valve 104 adjusts the air spring pressure. This symmetrical distribution shortens the air path distance between each valve and its corresponding actuator, improving control response speed.

[0042] According to one embodiment of the present invention, the two anti-slip valves 102 include a single-inlet anti-slip valve 102 and a double-inlet anti-slip valve 102.

[0043] In one embodiment of this utility model, the two anti-slip valves 102 are a single-inlet anti-slip valve 102 and a double-inlet anti-slip valve 102, respectively. The single-inlet anti-slip valve 102 has only one intake channel, which is used to receive gas input from a single air path, thereby controlling the pressure of the corresponding axle brake cylinder; the double-inlet anti-slip valve 102 has two independent intake channels, which can receive gas input from two different air paths, thereby achieving precise adjustment of the pressure of the other axle brake cylinder. The outlet channels of both types of anti-slip valves 102 are connected to the internal air path of the integrated substrate 100, and their mounting structures are adapted to the first valve mounting position of the integrated substrate 100, ensuring stable installation and normal operation.

[0044] The combined design of the single-inlet and dual-inlet anti-slip valves 102 allows the integrated module to adapt to the braking control requirements of different axles of railway vehicle bogies, eliminating the need for separate modules for different air intake methods and improving the module's applicability. The two types of anti-slip valves 102 can independently adjust the brake cylinder pressure for different axles, ensuring that the wheel and rail of each axle are always in an adhesive state, effectively preventing wheelset slippage or wheel rubbing. Furthermore, the integration of the two anti-slip valves 102 onto the same base plate avoids the complex air path problems caused by the dispersed arrangement of different anti-slip valves 102, simplifies the overall structure, and reduces maintenance difficulty.

[0045] According to one embodiment of the present invention, the integrated substrate 100 has a mounting plane, and both the first valve mounting position and the second valve mounting position are disposed on the mounting plane.

[0046] In one embodiment of this utility model, the integrated substrate 100 has a flat mounting plane, which provides a stable foundation for the installation of the anti-slip valve 102 and the balancing valve 104. Both a first valve mounting position and a second valve mounting position are provided on this mounting plane. There are two first valve mounting positions, used for installing a single-inlet anti-slip valve 102 and a double-inlet anti-slip valve 102, respectively; there is one second valve mounting position, used for installing the balancing valve 104. Each mounting position is provided with a connection structure for fixing the valves, ensuring that the anti-slip valve 102 and the balancing valve 104 can fit tightly against the mounting plane after installation, and that the valve's air passage interface 108 can accurately connect to the internal air passage of the integrated substrate 100.

[0047] A standardized mounting surface ensures that the positions of the first and second valve mounting positions are relatively fixed, guaranteeing the precise positioning of the anti-slip valve 102 and the balancing valve 104 after installation and preventing poor gas path connection due to installation position deviations. The valves fit snugly against the mounting surface, reducing the impact of vibration and improving valve operational stability. Furthermore, the mounting surface facilitates quick positioning of each valve during assembly, improving assembly efficiency and providing convenience for subsequent maintenance and valve disassembly and replacement.

[0048] According to one embodiment of the present invention, an air passage interface 108 and an electrical interface 110 for external connection are integrated on the integrated substrate 100; all air passage interfaces 108 and electrical interfaces 110 are arranged in the same direction.

[0049] In one embodiment of this utility model, the edge region of the integrated substrate 100 is integrated with an externally connected pneumatic interface 108 and an electrical interface 110. The pneumatic interface 108 communicates with the internal pneumatic path of the integrated substrate 100 and is used to receive external gas input or output gas to external actuators; the electrical interface 110 is used to connect to external control circuitry to realize electrical control of the anti-slip valve 102 and the balance valve 104. All pneumatic interfaces 108 and electrical interfaces 110 are arranged in the same direction, and a preset distance is maintained between the interfaces to avoid mutual interference. The structural design of the interfaces is compatible with the external pneumatic and electrical connectors of the rail vehicle to ensure reliable connection.

[0050] The unidirectional arrangement of the pneumatic interface 108 and the electrical interface 110 eliminates the need for frequent adjustments to the operating direction when connecting external pipes and lines, simplifying the connection process and improving installation efficiency. The centralized and unidirectional arrangement of the interfaces avoids the problem of pipes and lines crossing and tangling, resulting in a neat layout of pipes and lines around the integrated module, facilitating quick identification and maintenance during subsequent inspections. Furthermore, the integration of the interfaces onto the integrated substrate 100 reduces the dispersed placement of external interfaces, lowering the risk of interface damage or loose connections and improving overall reliability.

[0051] According to one embodiment of the present invention, both the first valve mounting position and the second valve mounting position are provided with interface through holes that communicate with the internal air passage; the anti-slip valve 102 and the balance valve 104 are respectively sealed and installed at the interface through holes by sealing elements.

[0052] In one embodiment of this utility model, both the first valve mounting position and the second valve mounting position are provided with interface through holes. These interface through holes penetrate the mounting plane of the integrated substrate 100 and communicate with the internal air passage, allowing the air passages of the anti-slip valve 102 and the balance valve 104 to connect with the internal air passage through the interface through holes. When installing the anti-slip valve 102 and the balance valve 104, the sealing element is first placed in the peripheral area of ​​the interface through hole, and then the anti-slip valve 102 and the balance valve 104 are respectively installed in their corresponding mounting positions, aligning the air passage interface 108 of the valve with the interface through hole. Simultaneously, the sealing element is pressed between the valve and the mounting plane, forming a sealing structure.

[0053] The through-hole design ensures precise alignment of the air passages for the anti-slip valve 102 and the balancing valve 104 with the internal air passages, preventing gas flow obstruction caused by misalignment. The use of seals effectively prevents gas leakage from the gap between the valve and the mounting surface, ensuring the airtightness of the internal air passages and guaranteeing the proper pressure regulation of the anti-slip valve 102 and the balancing valve 104. The sealed mounting structure eliminates the need for additional sealing pipes, simplifying the air passage connection method, reducing the risk of malfunctions due to poor sealing, and improving the operational stability of the integrated module.

[0054] According to one embodiment of the present invention, a pressure sensor 112 and / or a test connector 114 are also fixedly mounted on the integrated substrate 100, and the pressure sensor 112 and / or the test connector 114 are connected to the internal air passage.

[0055] In one embodiment of this utility model, a pressure sensor 112 and a test connector 114 are also fixedly mounted on the mounting plane of the integrated substrate 100. The number of pressure sensors 112 and test connectors 114 can be set according to monitoring requirements. The detection end of the pressure sensor 112 is connected to the internal air passage of the integrated substrate 100, enabling it to sense pressure changes in the internal air passage in real time. One end of the test connector 114 is connected to the internal air passage, and the other end is an open interface for connecting testing equipment during maintenance or debugging. Both the pressure sensor 112 and the test connector 114 are fixed to the integrated substrate 100 with bolts, and a sealing structure is provided at the connection point 122 between the two and the internal air passage to prevent gas leakage.

[0056] The pressure sensor 112 enables operators to monitor the internal air circuit pressure in real time, promptly detect pressure anomalies, and prevent malfunctions of the anti-slip valve 102 and balance valve 104 due to excessively high or low pressure, thus ensuring the braking safety and operational stability of the rail vehicle. The test connector 114 allows for pressure testing or gas sampling of the internal air circuit without disassembling the integrated module, simplifying the inspection and debugging process and reducing maintenance costs. The sealed connection between both connectors and the internal air circuit ensures the accuracy of the test data while preventing gas leakage from affecting the normal operation of the module.

[0057] According to one embodiment of the present invention, a mounting base 116 is also included. The mounting base 116 includes a first mounting portion 118 for fixing to the integrated substrate 100, a second mounting portion 120 for fixing to the rail vehicle, and a connecting portion 122 for connecting the first mounting portion 118 and the second mounting portion 120.

[0058] In one embodiment of this utility model, the valve assembly integration module further includes a mounting base 116. The first mounting portion 118 of the mounting base 116 is adapted to the bottom structure of the integrated substrate 100, and the first mounting portion 118 is fixedly connected to the integrated substrate 100 by bolts, so that the mounting base 116 and the integrated substrate 100 form a stable whole; the structure of the second mounting portion 120 is adapted to the chassis of the rail vehicle, and is used to fix the entire integrated module on the chassis; the connecting portion 122 connects the first mounting portion 118 and the second mounting portion 120, and its shape is designed according to the spatial distance between the chassis and the integrated substrate 100 to ensure that the mounting base 116 can adapt to the space under the vehicle.

[0059] The mounting base 116 ensures the integrated module is stably fixed to the chassis of the rail vehicle, preventing module swaying or displacement during vehicle operation and improving installation reliability. The first mounting section 118 and the second mounting section 120 are connected by a connecting section 122. The shape and size of the connecting section 122 can be flexibly adjusted according to the undercarriage space, allowing the integrated module to adapt to the undercarriage space layout of different vehicle models and improving its versatility. Furthermore, the mounting base 116 provides an independent mounting structure for the integrated module, eliminating the need for direct fixing to the vehicle body crossbeam, reducing dependence on the vehicle body structure and simplifying adaptation during vehicle model design.

[0060] According to one embodiment of the present invention, the connecting part 122 is provided with reinforcing ribs.

[0061] In one embodiment of this utility model, a reinforcing rib is provided on the connecting portion 122 of the mounting base 116. The reinforcing rib is arranged along the length direction or the force direction of the connecting portion 122 and is fixedly connected to the surface of the connecting portion 122 to form an integral structure. The number and distribution of the reinforcing ribs are determined according to the length of the connecting portion 122 and the load-bearing requirements, ensuring that the reinforcing ribs can evenly distribute the pressure borne by the connecting portion 122. The material of the reinforcing rib is the same as that of the mounting base 116, ensuring the strength and consistency of the overall structure.

[0062] The reinforcing ribs significantly enhance the structural strength and deformation resistance of the connection 122, effectively withstanding the weight of the integrated module and the vibrations and impacts generated during vehicle operation. This prevents the connection 122 from bending or breaking due to excessive stress, ensuring the load-bearing reliability of the mounting base 116. The reinforcing ribs achieve this strength increase without significantly increasing the thickness of the connection 122, controlling the overall weight of the mounting base 116 while ensuring strength, thus meeting the lightweight design requirements of rail vehicles. Furthermore, the integrated structure design of the reinforcing ribs avoids the assembly of additional components, reducing the risk of failure for the mounting base 116.

[0063] This utility model also provides a rail vehicle, including a car body underframe and the aforementioned valve group integration module; the valve group integration module is installed on the car body underframe.

[0064] According to the second aspect of the present invention, the rail vehicle with valve assembly integrated module is installed in the triangular space of the car body underframe, making full use of the idle space of the car body underframe and avoiding competition for installation space between the integrated module and other undercarriage components. This significantly improves the utilization rate of the undercarriage space of the rail vehicle, making the layout of undercarriage equipment more regular and meeting the design requirements of modularization and lightweighting. The mounting base 116 ensures a stable connection between the integrated module and the car body underframe. Even if the rail vehicle experiences vibration or impact during operation, it can prevent the integrated module from shaking, shifting, or falling off, ensuring the installation reliability of the integrated module and extending its service life. At the same time, the adaptability design of the mounting base 116 allows the integrated module to be adapted to the car body underframe structure of different models, eliminating the need to design separate installation structures for different models, reducing the workload of model design, and improving the versatility of the integrated module. The anti-slip valve 102 and balance valve 104 in the integrated module achieve functional coordination through internal air passages. The single-inlet and dual-inlet anti-slip valve 102 can precisely adjust the pressure of the brake cylinders on each axle of the bogie, effectively preventing wheelset slippage or wheel rubbing. The balance valve 104 can timely adjust the air spring pressure to ensure pressure stability during vehicle operation, thereby improving the braking safety and smoothness of the rail vehicle. The air passage interface 108 and electrical interface 110 on the integrated base plate 100 face outwards from the vehicle. During installation or maintenance, personnel can easily connect or disconnect pipelines and lines without disassembling the car body skirt or other peripheral components, significantly reducing installation difficulty and maintenance workload, and improving construction and maintenance efficiency. In addition, the integrated design replaces the traditional dispersed arrangement of the anti-slip valve 102 and balance valve 104, avoiding problems such as complex air passages and multiple failure points caused by dispersed components, reducing the risk of gas leakage, and improving the operational reliability of the rail vehicle's braking and suspension systems.

[0065] The rail vehicle includes a car body underframe and the aforementioned valve assembly integrated module. The car body underframe serves as the load-bearing foundation of the rail vehicle, providing a stable mounting platform for the valve assembly integrated module. A specific area of ​​the underframe is reserved for the installation of the integrated module. This space is located on the side of the underframe near the bogie, specifically the triangular area next to the bogie. This area can make full use of the unused space of the underframe and avoid occupying the installation positions of other critical components.

[0066] The valve assembly integrated module is fixed to the vehicle chassis via mounting base 116. The first mounting portion 118 of mounting base 116 is tightly connected to the bottom of the integrated base plate 100 of the integrated module by bolts, ensuring that mounting base 116 and integrated base plate 100 form a stable whole. The second mounting portion 120 of mounting base 116 is adapted to the preset installation position of the vehicle chassis and is also fixed by bolts, so that the entire integrated module is firmly assembled on the vehicle chassis. The connecting portion 122 of mounting base 116 connects the first mounting portion 118 and the second mounting portion 120. Its structure is designed according to the spatial distance between the vehicle chassis and the integrated base plate 100, which can adapt to the size characteristics of the triangular space and ensure that the integrated module will not interfere with surrounding components after installation.

[0067] The integrated base plate 100 in the valve group integrated module is formed by brazing multiple metal plates in layers. The internal air passage is kept sealed. Two anti-slip valves 102 (a single-inlet anti-slip valve 102 and a double-inlet anti-slip valve 102, respectively) are installed in the first valve mounting position of the integrated base plate 100, and the balance valve 104 is installed in the second valve mounting position. All three are connected to the internal air passage. The single-inlet anti-slip valve 102 and the double-inlet anti-slip valve 102 are used to control the brake cylinder pressure of different axles of the bogie of the rail vehicle, respectively. The balance valve 104 is used to adjust the pressure of the air springs on both sides of the bogie. The air passage interface 108 and the electrical interface 110 on the integrated base plate 100 are both oriented towards the outside of the rail vehicle. The air passage interface 108 can be connected to the external air passage pipeline, and the electrical interface 110 can be connected to the vehicle control circuit to realize the control of the anti-slip valve 102 and the balance valve 104 and the gas transmission.

[0068] According to one embodiment of the present invention, the valve group integration module is fixed to the triangular space on one side of the bogie of the car body underframe by the mounting base 116; the air circuit interface 108 and electrical interface 110 provided on the integration module for external connection both face the outside of the rail vehicle.

[0069] In one embodiment of this invention, the valve assembly integration module is fixed to the triangular space of the rail vehicle's underframe via the second mounting portion 120 of the mounting base 116. This triangular space is located on one side of the bogie and is an unused area of ​​the underframe. After installation, all externally connected pneumatic interfaces 108 and electrical interfaces 110 integrated on the module's surface face outwards from the rail vehicle, i.e., away from the vehicle's center. This orientation ensures that external pipelines and lines can be directly connected from outside the vehicle without passing through the vehicle's interior or other equipment areas.

[0070] Installing the integrated module within the triangular space of the vehicle's underframe fully utilizes unused space, avoids occupying key functional areas of the underframe, and improves the utilization rate of undercarriage space. Simultaneously, placing the integrated module close to the bogie shortens the connection distance for air and electrical circuits, improving control response speed. The air circuit interface 108 and electrical interface 110 face outwards, facilitating external connection operations for pipes and wiring without disassembling the vehicle's side skirts or other components, significantly improving installation and maintenance convenience. Furthermore, the outward-facing arrangement of the interfaces reduces interference from other components during vehicle operation, lowering the risk of loose connections.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
