Problems solved by technology

[0003] At present, the inspection and maintenance of EMUs including the bogies of EMUs is still blank in China. The technical structure of the bogies of normal-speed locomotives and vehicles is simple, and the reference for the inspection methods of high-speed EMUs bogies is limited. Therefore, in my country's high-speed With the rapid development of railway construction and the simultaneous implementation of the supporting high-speed motor car maintenance base, there is an urgent need for methods suitable for high-speed motor car bogie maintenance, so as to complete the repair of high-speed motor car bogies with high quality and efficiency, and ensure the safe operation of high-speed EMUs

Embodiment Construction

[0035] To further explain the technical solution of the present invention, according to the maintenance content, the motor vehicle bogie assembly line maintenance method involved in the present invention is divided into seven maintenance modules and 16 maintenance procedures, and the seven maintenance modules and 16 maintenance procedures are in accordance with the maintenance operation sequence Form a pipeline.

[0036] The seven maintenance modules are: pre-decomposition module, cleaning module, decomposition module, framework maintenance module, assembly module and test module.

[0037] The 16 maintenance procedures are as follows: Process 1—decompose the motor and bolster on the bogie and perform protective work before cleaning the bogie; process 2—clean the bogie as a whole, and dry it after cleaning;

[0038] Process 3—decompose the traction mechanism at the bottom of the bogie; process 4—decompose the secondary suspension components; process 5—decompose the primary susp...

Description

technical field [0001] The invention relates to rail vehicle maintenance technology, in particular to motor vehicle bogie maintenance technology. Background technique [0002] The bogie is one of the most important components of a rail vehicle. It plays the role of supporting the car body, steering and braking, and bears and transmits various loads and forces between the car body and the wheels, and between the wheel rail and the car body. The rolling of the wheel along the rail is transformed into the translation of the car body along the line, which plays a key role in ensuring the safe and stable operation of the vehicle on the track. The overhaul of rail vehicle bogies plays an important role in the whole vehicle overhaul, especially the EMU bogies with driving functions are complex in structure and sophisticated in technology, and the overhaul of EMU bogies is the core of EMU overhaul. [0003] At present, the inspection and maintenance of EMUs including the bogies of ...
