摘　　要：在汽车整车参数和发动机等已确定的情况下,传动比对整车动力性和燃油经济性有很大影响。本文根据发动机的外特性和万有特性,结合汽车的档位使用率,探讨如何选择传动系的传动比及其优化问题。最后给出传动比优化的算例,优化结果与国内外先进变速器的速比设置相比符合得较好。Based on the engine map, investigated in this paper are how to determine the transmisson ratios of the driveline and to achieve their optimization with considerations of vehicle practical running conditions. Some examples of transmission ratio optimizations are given and the results well coincide with the gear ratios of both domestic and foreign advanced automotive gearboxes.
