The Development And Experiment Of Passenger Coach Transmission

This paper is commenced from the demand and the competition of the local transmission market, and the passenger cars's gearbox market is comprehensively studied, accordingly, the development of the passenger cars's transmission is putted forward.The following aspects deemed to be the key factors of the passenger cars's transmission are studied.The evaluation index of the shift gear is putted forward firstly.From the aspect of fatigue and shift capability of the gear, according to the trend of high efficiency, the new compact evaluation method is putted forward, consequently the shift capability of the gear evaluation index is established.The technique realization and protection capacity is studied. At the foundation of the existing resources and dependable data ,the analysis of the technique assurance ability is conclude, including shift capability, assembly fatigue design and manufature etc. The conclution of the product could meet the market demand is putted forward finally.Contrasted various the analysis that shift gear to operate organization in detail, different material, rub a pair of synchronous machine structure function analysis, find out more excellent operation organization and shift gear structure.The capability of various shift gears and synchronizers are studied and the advanced operation mechanism is found.The theory of the moment of inertia of the shift gear whicth greatly effects the ability of the gear is highly studied .combined the process of the passenger gear development the introduction of the transmission design.The detailed gear profile and direction modification theory are studied and effective design method test method and validation method are putted forward.A better product verification method is gained after the data comparison and analysis, and some improvement of profession standard are putted forward, finally, the new evaluation method is established combined the fatigue and road test.According to the example of fatigue test-bed development, the principle of new test equipment development is putted forward and a new test control system is established.
