Introduction
Standard Evolution and Technological Innovation
GB/T 3367.3-2018 replaces the two 2000 versions of the standards, integrating the terminology systems of car body, bogie and brake device. The main technical changes include:
| Technical field | New content | Modified content | Deleted content |
|---|---|---|---|
| Body structure | Added 4 types of body definitions, 15 items such as living facilities cabinets | 8 terminology changes such as side wall→side wall | 5 items such as frame and fan |
| Braking system | 21 electronic components such as electro-pneumatic control unit | 6 terms such as wind horn→bagpipe | 3 mechanical control components |
Detailed explanation of core terms
Carbody structure system
Load-bearing carbody (2.1.1.1) is supported by both the underframe and sidewalls, and is typically used in high-power locomotives; Non-load-bearing carbody (2.1.1.2) is supported only by the underframe, and is mostly used in shunting locomotives.
Key bogie technologies
Radial bogie (2.2.1.1) uses a special guide mechanism to automatically position the wheels in the radial direction, improving the curve passing performance by more than 30%. Its core components include:
- Rubber joints (2.2.2.20): to achieve flexible positioning
- Anti-snaking shock absorbers (2.2.10.4.4): to suppress high-speed snaking motion
Modular evolution of brake systems
The standard reflects the technological transformation from pneumatic brakes to Electro-pneumatic control units (EPCU):
| Module name | Core function | Typical components |
|---|---|---|
| Balanced air cylinder control module (2.3.5.16) | Precise pressure control | REL/APP solenoid valve |
| Brake cylinder control module (2.3.5.18) | Brake force distribution | DBI interlock valve |
Implementation suggestions
- Comparison between old and new terms: Establish a mapping table for terms such as ceiling→top cover
- Maintenance focus: The energy absorption performance of the crush device (2.1.18.4) needs to be tested regularly
- Training points: Fault diagnosis process of electro-pneumatic brake module
