【摘要】 本文应用三轴系结点功率法，分析组合式无级变速器的传动效率，给出该类传动装置的效率计算公式，并通过具体实例与传动比法计算结果比较，更接近实测结果，为组合式无级变速器的设计提供了必要的依据。更多还原

【Abstract】 In this paper the driving efficiency of Combination Stepless Transmission has been analyzed by power method of mode of three axis. Then the efficiency Calculation formulaof this drive was given. According to this method the calculation result is come close to the measured result. It can be provided the base for the further design of the Combination Stepless transmission.更多还原
