传动效率是机械传动装置的一项重要技术指标，它直接反映机械传动装置传输动力的能力。本文针对混合动力汽车动力耦合器，利用电控动力传动系试验台试验了动力耦合器在不同的输入转速、扭矩以及温度下的传动效率。该传动效率值反映出动力耦合器在不同输入条件下的功率损失，可判断耦合器在不同条件下的结构变形、运动干涉以及异常磨损等多项性能。本试验不仅为动力耦合器传动效率试验方法提供了参考，还为混合动力汽车运行工况优化提供试验支持。

Transmission efficiency is an important technical index for mechanical gearbox,which directly reflects the capacity of gearbox transmission power.In this paper,a test bench is used to test the transmission efficiencies of the gearbox assembly for hybrid electric vehicle under differ- <br> ent input speeds,torques and oil temperatures.The values of the transmission efficiencies reflect the compared efficiencies of transmission assembly with different gears,which can be used to j udge the structure deformation of power coupler,the motion intervention,the abnormal wear and many other properties under different conditions.The test not only provides a reference for the test method for the transmission efficiency of power coupler,but also provides experimental support for quality assessment of hybrid electric vehicle.
