近年来,国外对提高双涡轮变矩器的液力机械变矩系数和效率而发表的分流方案专利文献很多。国内对它的评价又多引用假定的工作轮扭矩比,代入液机公式来进一步分析。但是,从变矩器的试验资料和水力计算结果来看,这种假定和分析是值得讨论的。本文按照正常的程序进行计算,所用的公式、几何参数和各种系数值业经第一种方案验证过,其计算特性与试验特性 In recent years, there are many patent documents published in foreign countries to improve the torque conversion factor and efficiency of the twin-turbo torque converter. Domestic evaluation of it and more reference to the assumption of the working-wheel torque ratio, substituted into the liquid machine formula to further analysis. However, from the torque converter test data and hydraulic calculation results, this assumption and analysis is worth discussing. In this paper, according to the normal procedure to calculate the formula used, geometric parameters and various coefficient values ​​have been verified by the first program, the calculation of the characteristics and experimental characteristics
