矿用汽车液力变矩器与发动机匹配的研究

Study to the Match between the Hydraulic Torque Converter and the Engine of the Tramcar

对矿用汽车液力变矩器与发动机匹配的原则和评价指标进行了分析研究,并对比了三种不同方案匹配的合理性。以SGA3722矿用汽车例,介绍匹配过程发动机和液力变矩器参数的选取与数学处理,对比采用与未采用该方案机械式变速箱汽车的动力性。

The paper makes the analytical study to the principle and estimation index of the match between the hydraulic torque converter and the engine of the tramcar, and compares the reasonability of three kinds of matching scheme. SGA3722 tramcar serving as the example, the paper intro- duces the selection and math process for the parameters of the engine and the hydraulic torque converter during the matching course, and compares the kinetics of the auto with and without mechanical gear- box.
