改变传动系单一匹配 提高整车燃油经济性

Improving Vehicle Fuel Econmy by Changing the Single Driving System Match

燃油经济性是载货汽车最重要的性能指标之一。选用具有代表性的几台样车，进行等速行驶燃油消耗量试验和多工况行驶燃油消耗量试验，对试验数据进行对比分析和理论计算，得到不同传动比对整车燃油经济性的影响，并据此设计了几种较为合适的传动系匹配方案，以满足不同用户的要求。

Fuel economy is one of the important performance target for the cargo truck. A few typical sample trucks are selected for the fuel consumption test under constant speed and multi - driving conditions. The comparison analysis and theoretical calculation are made to the test data. The effects of different transmission ratio on the vehicle fuel economy are known well. Based on this, a few relatively appropriate matching plan for the driving system is designed to meet the demads of different customers.
