Study On Electromotion Of The Bus Door Control System

This article based on rearch and analysis electric bus and its development of automatic control system. In view of many new serious guestions at domestic and abroad bus door automatic control system. According to the significant national policy which is saveing energy reducing platoon and environmental protection. We proposed the bus door electrically control system, contains the unloading spiral passergerbus door outside the bus and the electrically control system passenger busdoor inside the bus. And successfully developed the above two systems, has completed to their load bearing experiment,the life experiment,and the efficary experiment.This article introduced the main structure and the principle of work about the subject,elaborated its main characteristic is that the electricity power replace air power, by new special spiral vice-substitutes for the air pump,by new spiral slowing down transmission theory substitution worn and gear drive thecry. Thus achieves the purpose that the radial direction size very small,dece leration ratio very big also wnserves energy, reducing platoon, safety depend on that device, many kind of electrically control system, attractive looks and environmental protection.This article in satisfies the intensity, the rigidity and pendulum stabilitic and soon of this automatic control device. Reguest under the promise, as well as the diameter. Most to be small and the overall efficiency most to be high of the objective function, has carried on the optimized design, and obtained the best geometry parameter.In the article the innovation design the big load spiral organization of rouernut, the spring unloading organization. Style of displacement dyadic sheft coupling organization, elaborated their principle and function, has designed many runctions compound machine tool, in order to breaks through the difficulty about the big lead spiral processing technology and reduce the production cost of the system.In the article. We elaborated stressly, and designed the electrically, control system of the electrically busdoor, the multi-purpose control circuit, control remotely open door electrical gate,multi-ways vehicle door burglar alarm electric circuit and so on .
