Research And Development On High Speed Train Coupling

The coupling of the high-speed train is the key parts of drive system，which ourcountry need to import at present stage. Plaguing railway equipment manufacturing industryof our country for long time，it is a difficult problem to realize the localization of the traincoupling. Comparing several typical couplings of the high-speed train from home andabroad，this paper raise a scheme to used the GIICL as coupling of the high-speed train.In this paper, the following several aspects are researched，which contrapose thetechnical difficulties in the process of the developing of the high-speed train GIICL.Firstly，through the comparison and analysis of several kinds of typical foreign railway vehicleGIICL in structure features， combined with the situation of our country， this paper putforward the structure design of the high-speed train GIICL. According to the design planand related data based on the “gear manual”，this paper carried through the calculation indesign and gave the structure and size parameters of the GIICL，focusing on the analysis ofthe way of the GIICL reseting. Next to analys the hydrodynamic characteristics of GIICL，the results of the analysis can not only test the rationality of design of the coupling，but alsoprovide theoretical support for further optimization design of the coupling.Otherwise，paperdiscusses and analyses the transmission efficiency of coupling.According to the research ofcoupling transmission efficiency， this paper puts forward the method to reduce powerconsumption， improve the transmission efficiency， providing reasonable theory supportfor design development of GIICL. Finally involving the processing manufacturing of theGIICL，as we all know，a good design must be achieved through the processingmanufacturing.The paper analys the processing manufacturing of GIICL， the gearprocessing，heat treatment and seal and lubrication，this paper provides a better method ofprocessing of GIICL and designs a reasonable heat treatment process.Digestion and absorption of advanced foreign technology ia a very important way tocarry through technology innovation in our country. Through absorbing several foreignadvanced technology about high-speed train coupling， combined with the situation of ourcountry， this will provide support for promoting the localization of the train coupling.
