通过对汽车传动系统效率影响因素的分析,建立了传动系统各部件的功率损失模型,得出了传动系统效率的计算公式。在制定微型汽车传动系统效率试验标准的基础上,对某传动系统进行了试验测试。结果证明,通过理论模型得出的传动系统效率计算值与试验测试结果基本相符,在常用输入扭矩和输入转速范围内,其相对误差不大于6%。该理论模型为汽车传动系统的设计与优化提供了理论依据。

Through the analysis of factors affecting the efficiency of auto transmission system, the power loss models of all parts of the transmission system were established, and the formula of the transmission efficiency was obtained. On the basis of formulating the minicar transmission efficiency test standard, the transmission system was tested. Test results indicated that the transmission efficiency values which obtained theoretically by calculation were in reasonable agreement with experimental results, the relative errors were less than 6%, especially in commonly used input torque and input speed...
