整车动力传动系统优化匹配试验

Optimal Design and Test of the Vehicle Powertrain

以6×4半挂牵引汽车匹配的280kW发动机为主体,通过配装不同速比的桥,根据变速器的直接档和超速档分别进行加速性和经济性试验,然后分析所得的动力性和经济性数据确定整车匹配优化方案,从而降低整车油耗,为客户节约运输成本。

The power of engine is 280kW for the semi-trailer tractor “6×4” as an example, the data of power performance and fuel economy is obtained through the test of power performance and fuel economy changing axle ratio, direct gear ratio and overdrive gear radio, and that Determines optimal design plan of the vehicle powertrain. Then, it is reduced for the fuel consumption of vehicle, and it is reduced for the transportation costs of customer
