Description

Technical Field

[0001] The present invention relates to a modular configuration structure for at least two different variations of pressure control, a base module for such a modular configuration structure, a braking system having such a modular configuration structure, and a rail vehicle having such a modular configuration structure and / or a corresponding braking system. Background Technology

[0002] Different systems can be used for pressure control, and these systems differ in their components. For example, open-loop or closed-loop pneumatic brake controllers for rail vehicles can have different characteristics. This affects the pneumatic circuit diagram and configuration costs. On the other hand, the diversity of variants also necessitates separate structural space dimensions that must be considered for the corresponding installations. Summary of the Invention

[0003] The objective of this invention is to reduce the matching requirements for different variations of pressure control, particularly regarding configuration diversity and / or structural space determination dimensions.

[0004] This task is solved by the technical solution of the independent claim. Advantageous further improvements are provided by the technical solution of the dependent claim.

[0005] According to the present invention, a modular configuration structure for at least two different variations of pressure control comprises: a relay valve module with at least one relay valve; a configuration module with at least one functional unit having a variation-specific function; and a base module. The relay valve, the configuration module, and the base module are interconnected for pressure control. The base module has functionally identical components for the at least two different variations of pressure control.

[0006] Accordingly, functionally identical components can be combined in the basic module, while variant-specific matching can be achieved via relay valve modules and / or configuration modules. The term "functionally identical components" can refer to components that are functionally the same, and particularly structurally identical. However, if individual components change within the framework of the product lifecycle, modified components with the same functional range or at least the same minimum functional range can also be applied. Therefore, in the sense of the modular construction principle, functionally identical components refer to the identical parts included in the basic module within the module configuration structure.

[0007] By using a basic module for pressure control in at least two variants, at least one module, the basic module can be provided with the same structural space dimensions. Depending on the installation space dimensions of the variant used for pressure control, the variant is primarily derived only from variant-specific relay valve modules and / or configuration modules. Therefore, in a series arrangement along, for example, the length direction, the installation space dimensions can remain substantially the same in both the width and height directions. Furthermore, the unified basic module simplifies the pre-configuration of this modular structure.

[0008] The functional connection between the relay valve module, configuration module, and basic module refers to the direct or indirect connection between the modules. In other words, the modules are interconnected in such a way that pressure control is obtained through the connection between the modules.

[0009] In one design, the base module is operatively, particularly pneumatically, connected to at least one functional unit of the configuration module via at least one configuration module control line, and the output of the functional unit is operatively, particularly pneumatically, connected to the relay valve control input of the relay valve of the relay valve module via a relay control line.

[0010] In this regard, the configuration module control line represents a direct or indirect connection between the base module and the configuration module, wherein the output parameters of the base module, such as compressed air, are fed to the functional units of the configuration module. This feeding can occur via corresponding connectors of the base module and the configuration module, either feeding the output parameters of the base module to the connector or continuing to transmit the input parameters of the configuration module from the connector. The configuration module control line is used to continue transmitting the output parameters of the base module for controlling functional components or for matching via functional units.

[0011] For example, a functional unit of the configuration module could be a unit for matching the control pressure of a relay valve for a relay valve module, wherein the control pressure to be matched is supplied to the functional unit via a base module. The base module could, for example, have an upstream valve or valve assembly that pre-controls the control pressure to be matched. Therefore, variant-specific functional units can be designed only for a smaller re-control range, thus simplifying the implementation of the functional units to be installed in the configuration module.

[0012] In one design, the base module is operatively, particularly pneumatically, connected to the relay valve control input of the relay valve module via at least one relay valve control line.

[0013] Therefore, as an alternative or supplement to control via the configuration module, the relay valve can also be controlled via the basic module.

[0014] In one design, at least one output of the relay valve module, particularly the output of the relay valve of the relay valve module, is connected to the working ground of the base module, particularly pneumatically, via a base module pipeline.

[0015] For example, the base module may have a sensor connected to the base module piping and determining the pressure matched by the relay valve. In other words, the monitoring function of the relay valve output parameters is transferred from the relay valve module to the base module via the base module piping, or is thus implemented in principle within the base module.

[0016] In particular, the at least one basic module pipeline is connected to another basic module pipeline via a functional component, particularly pneumatically.

[0017] For example, the other base module pipeline, which is connected to the at least one base module pipeline via a functional component, is a pipeline leading from the output of the relay valve into the base module, and thereby continues to transmit the relay valve output pressure to the braking medium. The functional component can be configured such that the pressure in the other base module pipeline can be released or reduced via the functional component. For this purpose, the functional component may, for example, be a check valve.

[0018] In one design, the functional unit of the configuration module has at least one pressure-limiting valve or at least one pressure-reducing valve.

[0019] Accordingly, the general output pressure, such as that which continues to be transmitted from the base module to the configuration module as described above, can be further matched in a variant-specific manner by a pressure relief valve or a pressure reducing valve.

[0020] In particular, the functional unit has the at least one pressure relief valve in at least one of the at least two variations for pressure control, and the at least one pressure reducing valve in at least one additional variation of the at least two variations for pressure control.

[0021] Therefore, the matching via the configuration module in one variant is at least in the pressure limitation via the pressure relief valve, while in the other variant it is at least in the pressure reduction via the pressure reducing valve.

[0022] Alternatively or additionally, the functional unit has at least one first-type pressure relief valve in at least one of the at least two variations for pressure control, and at least one second-type pressure relief valve in at least one additional variation for pressure control.

[0023] Therefore, variant-specific matching via the configuration module involves at least two different variant-specific pressure relief valves.

[0024] Alternatively or additionally, the functional unit has at least one first-type pressure reducing valve in at least one of the at least two variations for pressure control, and at least one second-type pressure reducing valve in at least one additional variation for pressure control.

[0025] Therefore, variant-specific matching via the configuration module involves at least two different variant-specific pressure reducing valves.

[0026] In one design, the relay valve module, in particular the relay valve, in at least one of the at least two variations for pressure control is different from the relay valve module, in particular the relay valve, in the at least one other variation.

[0027] Therefore, as an alternative or supplementary solution to matching the module configuration structure via the configuration module for a specific variant, the module configuration structure can be matched for a specific variant via the relay valve module.

[0028] In another aspect, the present invention relates to a base module for the above-described module configuration structure, wherein the base module has at least one valve unit for matching pressure and / or at least one sensor unit for determining pressure.

[0029] The input pressure can be matched to the output pressure of the base module via the at least one valve unit.

[0030] The at least one sensor unit may be, for example, a pressure sensor or other sensor that detects a signal corresponding to pressure. Therefore, determining the pressure refers to direct or indirect measurement. This allows not only the determination of the pressure of the output parameters of the configuration module and / or relay valve module guided by the base module, but also the monitoring of the pressure matched by the base module itself.

[0031] In one design, the base module has at least one reservoir for providing pneumatic pressure.

[0032] For example, a reservoir can be configured to compensate for pressure fluctuations in order to provide a stable pressure level for control. The reservoir can also be referred to as a pre-control volume or part of a pre-control volume.

[0033] In one design, the base module has at least one output and / or input terminal for connection to the configuration module and / or at least one output and / or input terminal for connection to the relay valve module.

[0034] The base module can be connected to the corresponding input of the configuration module or the relay valve module via its corresponding output. As described above, for example, the control pressure for the relay valve can be transmitted as an output parameter of the base module to the functional unit via the input of the configuration module, so that the variant can be specifically matched to the control pressure for the relay valve.

[0035] Similarly, the base module can receive output parameters from the configuration module and / or the relay valve module via different input terminals in order to determine and / or match the output parameters.

[0036] In particular, the basic module has at least one valve, especially a solenoid valve, for matching the pressure at the output end used for connection with the configuration module.

[0037] This involves the specific design scheme of the pre-control module of the basic module as a configuration module.

[0038] In one design, the base module has at least one sensor for determining the pressure at the output terminal for connection to the relay valve module.

[0039] This involves the specific design of the basic module as a monitoring and / or control module for the relay valve module.

[0040] The features of the base modules described above in the description of the module configuration structure can also be applied to the base modules themselves. Similarly, the features of the module configuration structure described for the base modules can be applied to the module configuration structure if they have not already been described therein.

[0041] In another aspect, the present invention relates to a braking system having at least one of the above-described modular configuration structures and a pneumatic braking unit, wherein the relay valve is configured to match the braking pressure for the pneumatic braking unit.

[0042] The relay valve can be controlled based on its connection to the base module and / or the configuration module.

[0043] The features described above regarding the module configuration structure and / or base module can also be applied to the braking system. Similarly, the features described for the braking system concerning the module configuration structure and / or base module can be applied to that module configuration structure and / or base module if they have not already been described therein.

[0044] In another aspect, the present invention relates to a rail vehicle having the above-described modular configuration structure and / or the above-described braking system.

[0045] The modular configuration structure is used for applications in rail vehicles, and is not limited to pressure control for braking systems, but can also be used for other pressure control purposes.

[0046] The features described above regarding the modular configuration structure, basic modules, and / or braking systems are equally applicable to rail vehicles. Similarly, the features described for rail vehicles concerning the modular configuration structure, basic modules, and / or braking systems can be applied to those modular configuration structures, basic modules, and / or braking systems if they have not already been described therein.

[0050] Figure 2 This demonstrates an application that can be used Figure 1 A schematic diagram illustrating an exemplary implementation of the basic modules of the module configuration structure. Detailed Implementation

[0051] Figure 1 A schematic diagram illustrating an exemplary embodiment of a modular configuration structure is shown. The modular configuration structure includes a base module 1, a relay valve module 2, and a configuration module 3. The relay valve module 2 has a relay valve 40 with two relay valve control inputs 41 and 42. The configuration module 3 has a functional unit 50, here a pressure relief valve. In this embodiment, the relay valve 40 and the functional unit 50 are variant-specific components for a variation of pressure control, but will be referred to later. Figure 2 The configuration of the basic module 1 described is independent of the variant. However, in other embodiments, only the configuration module 3 or the relay valve module 2 may have variant-specific components, particularly variant-specific functional unit 50 or variant-specific relay valve 40.

[0052] The base module 1 is connected to one of the relay valve control inputs 42 via a relay valve control line R1. In this embodiment, the connection is made via the base module output and the relay valve module input. The relay valve control line R1 may also pass through the configuration module 3 before connecting to the relay valve control input, for example, when a different variant-specific function is to be implemented via the configuration module 3. For example, compressed air can be matched via a solenoid valve in the configuration module, or additional sensors can be arranged along the relay valve control line R1 to detect and measure parameters. The relay valve control line R1 may pass through the configuration module upstream and / or downstream of the base module 1. Furthermore, the base module 1 is connected to the relay valve output via a base module line R4. The relay valve output refers to the output pressure to be controlled by the relay valve 40. For this purpose, the relay valve module 2 has a corresponding relay valve output and the base module 1 has a corresponding base module input. The base module 1 also has a base module output, which is connected to the relay valve input of the relay valve 40 via a base module line R2. Another base module output is connected to the relay valve input of relay valve 40 via another base module line R3. Furthermore, base module 1 is also connected to functional unit 50 via configuration control line C1, allowing the supply of compressed air to functional unit 50, which is then further matched by functional unit 50. The matched compressed air is then supplied to the other relay control input 41 via relay valve control line C2. In this embodiment, relay valve 40 is controlled via relay valve control input 41, provided that the pressure introduced into relay valve control input 41 is greater than the pressure applied to relay valve control input 42. However, in other embodiments, the decisive control pressure for relay valve 40 can also be influenced in parallel by the two relay control valve inputs 41, 42, and / or the decisive change of the relay valve control input can be performed by a control device based on braking type, operating state, or other influencing parameters. In yet another embodiment, relay valve 40 can also be operated solely via relay valve line R1 and the connected relay valve control input 42. Accordingly, control via relay valve control line C2 can be cancelled, and relay valve 40 only has relay valve control input terminal 42. In this embodiment, relay valve control line C2 is guided through base module 1 to achieve a compact modular configuration. In other embodiments, a pressure sensor or a sensor for detecting parameters representing pressure may also be provided in base module 1, connected to relay valve control line C2.

[0053] Figure 2 This shows an application that can be used Figure 1This is a schematic diagram of an exemplary implementation of the basic module of the modular configuration structure. The basic module 1 has two solenoid valves 12 and 13, which control compressed air during service braking. Another solenoid valve 11, located downstream of solenoid valves 12 and 13 in the direction of compressed air flow, can also directly continue to conduct compressed air during emergency braking, unaffected by solenoid valves 12 and 13. The output of solenoid valve 11 is connected to the functional unit 50 of configuration module 3 via configuration module control line C1—as described above. Configuration module control line C1 is connected here to a reservoir 30 of basic module 1, through which compressed air can be supplied or received. Reservoir 30 is used to compensate for pressure fluctuations in configuration module line C1 and thus achieve a stable pressure level for control. A pressure sensor 21 is arranged between the connection point of reservoir 30 on configuration module control line C1 and the corresponding output of the basic module, through which the pressure output at the output of the basic module via configuration module control line C1 can be monitored and supplied to the associated controller. Therefore, the base module 1 provides control pressure to the relay valve 40 via the configuration module control line C1, and this control pressure is matched in a variant-specific manner via the functional unit 50. In other words, the base module 1 can be used for pre-control, while the configuration module performs variant-specific subsequent control.

[0054] The base module line R4, originating from the relay valve output of the relay valve 40, passes through the base module 1, which has a pressure sensor 24 connected to the base module line R4 to monitor the output pressure of the relay valve 40 toward the braking medium to be applied output pressure and supply it to the associated controller.

[0055] Furthermore, base module 1 has a pressure sensor 22 connected to the input of one relay valve via base module line R2 to monitor the input pressure to be matched by relay valve 40. Another pressure sensor 23 of base module 1 is connected to another base module line R3, which is connected to the output of the other relay valve. Furthermore, the other base module line R3 is connected to base module line R4 via a check valve 14, which functions as a check valve. Check valve 14 can release or reduce pressure in base module line R4 via relay valve control line R3. Here, pressure sensor 23 is positioned upstream of the connection between base module lines R3 and R4. Therefore, pressure sensor 22 detects the direct input pressure relative to the corresponding relay valve input, while pressure sensor 23 detects the input pressure relative to the other relay valve input, unaffected by the connection between base module lines R3 and R4 via check valve 14.

[0056] This invention is not limited to the described embodiments. In particular, features described regarding embodiments of the invention, other aspects of the design, and further improvements can be combined with each other, provided they do not unreasonably exclude each other. Furthermore, valves, sensors, and / or functional units can be implemented redundantly. In particular, the sensors of the base module, especially all sensors, are redundantly arranged. Accordingly, for example, a corresponding sensor is set at least twice (individually) with respect to a measurement parameter and connected to a corresponding pipeline. For example, the base module 1 has two pressure sensors 21 along the configuration module control pipeline C1. Preferably, the connection of these two pressure sensors 21 on the configuration module control pipeline C1 is arranged such that no intermediate components that could affect the measurement parameter are arranged between the connection points of the pressure sensors 21 on the configuration module control pipeline C1. Furthermore, the base module may have a specific configuration regarding the connection of the solenoid valve 11 for emergency braking. The solenoid valve 11 may be directly provided for the passage of compressed air and can operate accordingly. Alternatively, a piston valve operated by the solenoid valve 11 may be provided instead of the solenoid valve 11 for the passage of compressed air. If the solenoid valve 11 itself—that is, without a piston valve, and especially without a piston valve with a relatively large cross-section—is configured for compressed air passage, a more compact structure of the basic module 1 can be achieved. The solenoid valve 11 can include a common switching magnet, on which all three input terminals are used. In particular, the solenoid valve 11 has an armature, which is mounted via a corresponding connector. Furthermore, a reservoir 30 can also be arranged between the solenoid valves 12 and 13 for service braking. Thus, particularly regarding the passage of compressed air through the solenoid valve 11 itself, a higher exhaust speed can be achieved after emergency braking. Therefore, depending on the arrangement of the reservoir 30, i.e., as... Figure 2 The described or application-appropriate matching can be performed between solenoid valves 12 and 13.
