【正文】 values of the pitchline shese cases it is often good design practice to go to the spiral bevel gear,which is the bevel counterpart of the helical in the case of helicaal gears,spiral bevel bears give a much smoother tooth action than strain bevel gears,and hence are useful where high speed are is frequently desirable,as in the case of automotive differential applications,to have gearing similar to bevel gears but with the shaft gears are called hyoid gears because their pitch surfaces are hyperboloids of revolution,The tooth action between such gears is a bination of rolling and slidin along a straight line and has much in mon with that of worm gears. A shaft is a rotating or stationary of circular cross section,having mounted powertransmission subjected to bending,tension,pression,or torsional loads,acting singly or in bination with one another,When they are bined,one may expect to find both static and fatigue strength to be important design considerations,since a single shaft may be subjected too static stresses,pletely reversed,and repeated stresses,aii acting at the same time. The word “shaft” cover numerous variationgs,such as axles and axle is a shaft,either stationary or rotating,not subjected to torsion short rotating shaft is often called a spindle. When either the lateral or the torsional deflection of a shaft must be held to close limits,the shaft must be sized on the basis of deflection,before analyzing the stresses,The reason for this is that,if the shaft is made stiff enough so that the deflection is not too large,it is probable that the resulting stresses will be safe,But by no means should the designer assume that they are safe。 r is the driving wheel radius。v and a are the vehicle running speed and acceleration respectively. According to vehicle dynamics,the vehiclerunning speed is determined by the balance between engine traction force and running resistance and can be expressed as tvDeg gdGdvACfGTrii ??? ???? 20 )s i n( (2) Where eT is the engine out put torque。 adaptive control。外文文獻翻譯 附錄 A（英文原文） Adaptive Clutch Engaging Process Control Automatic Mechanical Transmission LIU Hai’ou(劉海鷗 ),CHEN HUI’yan(陳慧巖 ),DING Hua’rong(丁華榮 ),HE Zhong’bo(何忠波 ) Abstract: Based on detail analysis of cluch engaging process control targets and adaptive demands,a control strategy which is based on speed signal,different from that of based on main clutch displacement signal,is put considers both jerk and slipping work which are the most monly used quality evaluating indexes of vehicle starting adaptive control system and its reference model are discussed the adaptability to different starting gears and different road conditions as examples,some proving field test records are shown to illusrate the main clutch adaptive control strategy at starting field test gives acceptable results. Key words: automatic mechanical transmission(AMT)。 transmission technology。 main clutch engagement
