摘　　要：传动系参数是决定客车动力性和燃油经济性的主要参数,传统的客车传动系优化方法中没有考虑到实际工况对客车动力性和燃油经济性的影响。然而客车在实际使用中载质量变化明显,对客车动力性和燃油经济性有显著影响。本文考虑到载质量变化对车辆燃油经济性和动力性的影响,建立了考虑载质量变化的客车传动系参数优化模型和优化方法。优化实例表明,采用该优化方法效果明显。Transmission parameters is the main parameter having effect on the performance and fuel economy of the bus, the traditional way of bus transmission parameters optimum method did not consider the effect of actual working condition. However, the load has deeply effect on the bus power and fuel economy when it changed sharply in the bus driving. This paper considers the effect on the bus power and fuel economy of load changing, builds the optimization model of bus powertrain based on load changing. The optimization results indicate that this optimum method have a obviously optimal effect.
