碩士 === 國立中山大學 === 機械工程研究所 === 84 === Gear-type automatic transmissions can provide several speed ratios by means of interengaging different elements of the gear trains and the output shaft by the centrifugal clutches, and they are widely used in mechanical systems. The purpose of this work is to develop a systematic methodology for the configurations and kinematic designs of gear-type automatic transmissions for two-wheel vehicles. First, we analyze the system and find the basic characteristics of automatic transmissions out. According to these characteristics, the design procedures for both ordinary and planetary gear systems are detablished : a caralog of automatic transmissions configurations is set up from the atlas of geared kinematic chains. Then, according to the given speed ratios, a systematic porcedure for the kinematic design of gear systems is successfully developed. The teeth numbers can easily be found by using such a procedure. Finally, we can have multi- speed transmissions by combining the ordinary and planetary gear systems and present several design examples of 4-speed and 5- speed automatic transmissions as a result of this work. The results of this work are of benefit to the design of gear-type automatic transmissions for two-wheel vehicles.
