DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] A design method for a modular braking system for a railway freight car provided in an embodiment of the present application is used for modular design of the braking system of a railway freight car to improve the modular design and assembly efficiency of the braking system of a railway freight car, especially for diversified export products. It should be noted that the modular braking system, design method and device for a railway freight car in an embodiment of the present application are suitable for railway flat cars, covered cars, open cars and other models with relatively concentrated braking systems. Figure 1 A schematic diagram of a design method for a modular braking system for a railway freight car provided in an embodiment of the present application, referring to Figure 1 It can be seen that the design method of the modular braking system of railway freight cars includes: S1: Modular classification of truck braking systems based on product body structure; Among them, the modular classification method of the truck brake system specifically includes classification according to the braking function, control method, installation location, working conditions, etc. of the brake system. In this embodiment, the brake system is mainly divided into modules according to the control method of the brake system. The brake system is mainly divided into pneumatic braking, electronic control braking and manual control braking according to the control method. Pneumatic braking is the mainstream method of railway braking system, mainly including compressed air source, brake control valve, brake pipe, brake cylinder, etc. Different trucks may be equipped with different pneumatic control units. For example, heavy-duty trucks may need enhanced pneumatic brake modules, while ordinary freight trucks only need basic pneumatic modules; electronic control braking is used for intelligent and modern trucks, using electronic signals to control brake valves and brake cylinders, thereby achieving more precise braking control, which is suitable for high-speed trucks or special trucks that require precise control; manual control braking is used for brake systems that require manual operation, generally as a backup device. This module is suitable for old models or special trucks that require manual intervention.

[0029] In the embodiment of the present application, according to the vehicle structure and the working principle of the brake system, the brake system is divided into a control valve module 100, a brake main pipe module 300, an empty weight valve module 400 and a brake cylinder module 200.

[0030] In one embodiment, the truck brake system is a conventional lever brake, and the brake cylinder module 200 of the conventional lever brake includes a brake cylinder 201, a brake shoe clearance adjuster 202, a brake lever 203, and an upper pull rod 204. Figure 2 As shown, the upper pull rod 204 is connected to the brake disc on the bogie to change the braking force through mechanical transmission.

[0031] In another embodiment, the truck braking system is an integrated brake, and the brake cylinder module 200 of the integrated brake adjusts the braking force through electronic control, such as Figure 3 As shown, the outlet pipe of the empty weight valve 401 is connected to the brake cylinder used to drive the brake disc movement, and a brake signal transmission system module is additionally added to the control valve module 100 of the lever-type brake. Specifically, the control valve module 100 includes an electro-pneumatic brake control valve 101, a CCID middle junction box 105, an armor cable 106, an end EOC junction box 107, and a truck connecting cable 108. The brake valve and the air pressure of the brake cylinder are controlled by the circuit to adjust the braking force.

[0032] By dividing the braking system into four modules that can realize basic braking functions according to the vehicle structure, the complex system can be decomposed into four modules that can be independently designed, manufactured and tested, which helps to improve design efficiency.

[0033] S2: Determine the resource allocation of each brake system module according to the division result, which specifically includes the following steps: Clarify modular division and resource requirements. Specifically, according to the modular division of the truck brake system, determine the function and structure of each module, and list the resource requirements for each module, including the required parts, materials, process parameters, testing equipment, etc.; Establish resource libraries and standard configurations, set up standard configuration lists for each module, clarify the specifications and technical requirements of each component, create a component library in the resource library, store the specifications, inventory and supplier information of commonly used parts, facilitate reuse and unified management, and include installation processes, maintenance tools, assembly equipment and other information to ensure the integrity of resource configuration of each module; Define the interfaces and common resources between modules, identify the interfaces between modules (such as connectors, connection methods, etc.), ensure the interconnection compatibility between modules, and set up a list of common resources to be used, including common parts and public tools, to achieve resource sharing between modules and reduce costs; Systematic resource configuration: by selecting a suitable database, such as a relational database or a NoSQL database, the resource information of each module can be systematically managed. The database should contain information such as module type, parts list, supplier, procurement cycle, etc. The resource library information can be embedded into the 3D design software to associate the design with the resource library, ensuring real-time call of resource information during the design process.

[0034] In this embodiment, by collecting the information of the components of each module of the brake system, a resource library of the components of each module is established, and the components of each module are configured according to the vehicle structure. The resource library is divided into a common module column and several brake system module columns according to the vehicle structure, each module column includes several sub-module columns, and each sub-module column includes the drawing number, name and version number of several components.

[0035] S3: determining the positioning reference of each brake system module according to the resource configuration of each brake system module, and completing the overall layout design of the brake system according to the resource configuration and positioning reference of each brake system module; Wherein, determining the positioning reference of each brake system module specifically includes the following steps: Analyze the functions and structures of the modules, understand the functions and installation positions of each brake system module, analyze the positioning accuracy and interface requirements required in the system, and determine the main functional areas of each module (such as interface surfaces, connection holes, etc.), which will be used as candidate areas for positioning references; Determine the positioning reference. According to the structure and interface design of the module, select a reference surface (such as the module base or support surface) with rigidity, accuracy and versatility as the main positioning reference. For key connection points (such as bolt holes, pin holes, etc.), ensure that they correspond to the assembly reference of the vehicle body structure to ensure easy alignment during the assembly process. Preferentially select the surface or hole adjacent to the center beam, pillow beam or cross beam lamp support structure of the vehicle body as the reference so as to quickly and accurately connect with the vehicle body; Use design software to create positioning annotations. In the 3D design software, mark the positioning reference for each module, record the coordinates, dimensions, relative position and other information of each reference surface and hole, and mark the reference symbols and annotations in the design model to ensure that the positioning information can be clearly identified during the design, production and assembly process; Simulate and verify positioning accuracy. Use the simulated assembly function in the design software to verify whether the positioning reference of each module can meet the accuracy requirements and ensure that there is no interference between modules and between the module and the vehicle body. If the positioning effect of some references is not ideal, adjust the position of the reference surface or hole to optimize the positioning solution. The tooling design of the positioning reference should be based on the design of the corresponding assembly tooling equipment, such as positioning fixtures and guide tools, to ensure that the module can be positioned quickly and accurately during assembly. The tooling design should be coordinated with the positioning reference to simplify the positioning process and improve assembly efficiency.

[0036] In the embodiment of the present application, when the brake module is a control valve module 100, the control valve 101 is used as the positioning reference; when the brake module is a brake main pipe module 300, the main pipe tee 301 joint is used as the positioning reference; when the brake module is an empty weight valve module 400, the empty weight valve 401 is used as the positioning reference; when the brake module is a brake cylinder module 200, the brake cylinder 201 is used as the positioning reference; The positioning reference position of each module is determined according to the transverse center line, longitudinal center line and vertical center line of the vehicle body, and the positions of other components are determined according to the positioning reference position.

[0037] In step S3, completing the overall layout of the braking system specifically includes: Reasonable allocation of space: According to the resource allocation requirements of each module of the brake system (such as parts, materials, interfaces, etc.), the installation space of the brake system is reasonably allocated to ensure that each module has enough space on the vehicle body structure, and there is no interference between modules and between modules and the vehicle body, so as to meet functional requirements and ensure easy installation and maintenance; According to the positioning datum set in the early stage, ensure that the datum surface of all modules is aligned with the structural datum of the vehicle body. For example, the positioning datum of the brake system and other components should be precisely connected with the interfaces of the vehicle body supporting structure such as the center beam, bolster beam and cross beam; Design dedicated assembly tooling and positioning fixtures for each module to ensure that the module can be accurately aligned with the reference position during the assembly process, thereby improving assembly efficiency and quality. The tooling can be customized according to the positioning reference and module specifications.

[0038] The embodiments of the present application achieve a standardized process from design to assembly by coordinating resource library management, three-dimensional software design, and setting positioning references, bringing significant advantages in improving production efficiency, reducing costs, enhancing system performance, and ensuring quality.

[0039] Since different countries and regions have strict standards and regulations on the safety, quality and environment of railway freight cars, modular design and standardized resource allocation can ensure that the braking system meets the technical standards and certification requirements of various countries and improve the compliance of export products in the international market. In addition, the railway construction and operation conditions in different countries or regions are different. The modular design method allows the braking system to be customized according to different customer needs to meet the climate, terrain and transportation requirements of different regions. At the same time, modular design not only helps to simplify the design and production process of the freight car braking system, but also improves the flexibility and efficiency of production. Enterprises can quickly combine and customize the braking system in different freight car projects by establishing standardized modules, shortening the production cycle and improving delivery speed.
