摘要： 驱动桥效率随输入扭矩、转速的变化而时刻变化，为提高其在整车性能计算应用中的 准确度，通过对驱动桥瞬态下系统阻力矩变化规律的探索，建立驱动桥阻力矩与输入扭矩、 转速的变化公式，实现动态工况下驱动桥效率的精确计算。通过对现有几组驱动桥阻力矩结 果准确度的验证，表明通过阻力矩法建立的驱动桥瞬态效率计算公式在简化系统计算难度的 同时，提高了整车性能计算精度，并可推广到传动系其他系统效率计算中，也可简化驱动桥 效率试验测点数量。

Abstract: The efficiency of the drive axle changes constantly with changes in input torque and speed. In order to improve its accuracy in vehicle performance calculation applications, by exploring the variation law of the system resistance torque under transient conditions of the drive axle, a formula for the variation of the drive axle resistance torque and input torque and speed is established to achieve accurate calculation of the drive axle efficiency under dynamic working conditions. By verifying the accuracy of several existing sets of drive axle resistance torque results, it is shown that the transient efficiency calculation formula of the drive axle established through the resistance torque method not only simplifies the difficulty of system calculation, but also improves the accuracy of vehicle performance calculation. It can be extended to the efficiency calculation of other system efficiency calculation, and can also simplify the number of test points for drive axle efficiency.
