摘　　要：文章通过对特定工况下牵引车不同动力配置的分析研究,探讨"超速档+大速比",与"直接档+小速比"对于特定工况的动力性、传动效率及燃油消耗率对比,从而得出针对特定工况的动力配置的结论。常年来,在客户中存在一种观点"总速比相同,同马力时车辆的动力,后桥速比小的动力性较差",对于此观点,文章将进行分析,探讨此观点的科学性和局限性。最后,就此基础上,得到指导相应工况下的动力配置的合适方案。This article discusses the"overspeed plus large speed ratio"and the"direct speed plus small speed ratio"for specific conditions of power,transmission efficiency and fuel consumption by analyzing the different power configurations of tractors under specific working conditions.The ratio is compared to the conclusion of the power configuration for a particular operating condition.Over the years,there is a view among customers that the total speed ratio is the same as that of the vehicle at the same horsepower.For this point of view,this paper will analyze and explore the scientific nature of this viewpoint and limitations.Finally,on this basis,a suitable solution to guide the power configuration under the corresponding working conditions is obtained.
