自动变速器效率与液力变矩器的透穿性

Efficiency of Auto Transmission and the Penetrativity of Hydraulic Torque Converter

分析对比液力变矩器原始特性和动力特性 ,讨论了当外界阻力发生变化时 ,具有不同透穿性的液力变矩器速比的变化规律及其对变速器传动效率的影响 ,指出在自动变速器设计中 ,合理选择液力变矩器的结构参数 ,特别是注重其透穿度与发动机适应系数的合理匹配 。

analyzing the primary characteristic and the power performance, this article discusses the changing regularities of the ratio in two types of HTC, which have different penetrativity. The effect to the AT efficiency is also discussed. It is pointed out that to find the best match of the percentage of penetrating and engine accommodation coefficient is a good way to increase AT efficiency and car driving power.
