双涡轮液力变矩器在我国正得到较为广泛地应用,但对其特性的研究还进行得不多。为提高性能以及为系列工作提供资料,我们对双涡轮液力变矩器进行了初步的试验研究。双涡轮液力变矩器作为一种内分流的液力机械式变矩器,其叶轮部分和汇流机构应作为一个不可分割的整体看待,图1是结构简图和无因次特性曲线图。图中以第Ⅰ涡轮的脱开点A为界,把转速比分成二个区域即二个涡轮共
Twin-turbo torque converter is being widely used in our country, but the research of its characteristics has not been much. In order to improve the performance and provide information for the series of work, we conducted a preliminary experimental study on the twin turbine torque converter. As an internally shunted hydromechanical torque converter, the impeller portion and the confluence mechanism of a twin-turbo torque converter should be treated as an integral whole. FIG. 1 is a structural diagram and a dimensionless characteristic diagram. Turbine in the figure to take off point A for the sector, the speed ratio is divided into two regions that a total of two turbines
