Safety Technical Requirement And Performance Detecting Research For City Bus

City bus safety performance directly affects the urban public traffic safety. City bus hasvariaty sorts, diverse structural types, special operating environment, and complex operatingconditions. The safety technical regulations and standards on city bus are poor in China. Thesafety technical requirements and key detection technologys of city bus should be study, so asto provide safety operating vehicle technical standards for urban public transport operators.Outline current situation of European and American automobile technical regulationssystems and domestic automobile standard system, compare domestic and foreign automobilestandards and regulations, master city bus technical contents in existing national, industry andlocal standards. Analyzing domestic urban bus standards and investigating manufacturers andautomobile detection mechanism, it shows that domestic city bus before sold should do typetest, mandatory inspection and CCC check etc.. Analyzing accident features and operationconditions of urban bus, it remarks that safety problems mainly forms in the braking system,transmission mechanism, steering system, fire prevention and emergency escape device etc.,so more attention should pay on requirements of clutch, brake, transmission, suspensionsystem, tire, wiring harness layout and extinguishing equipment.Comparing items ofAutomobile Safety Performance Test and Road Transport Vehicle ComprehensivePerformance Test, according to actual situation of city bus safety test, it points out that justdoing current Automobile Safety Performance Test is not good enoght to assure vehicleperformance. By testing and combining safety technology requirement of city bus, studiessuggest that should perfect forward technical requirements of urban bus’ safety device,prevent burning and fire prevention, escape ect., and form a suggesting version standardnamed “Safety property requirements and test methods for city bus” lastly.
