Abstract:Evaluation method and improvement str ategy of dynamic gear-shift performance of passenger
car with manual tr ansmission were analyzed. Three objective evaluation indexes used for dynamic gear-shift performance evaluation were presented based on subjective evaluation requirements. And the corresponding improvement str ategies were discussed with consideration of the str uctural characteristics of the tr ansmission. Based on these works, experimental analysis was carried out to verify the presented conclusions.
Keywords:tr ansmission; gear shift performance; dynamic; passenger car
