The Transmission performances of Traction Infinitely Variable Transmission Used in Electric Vehicle Power Train

摘要：

　　The traction infinitely variable transmission (TIVT) used in the power train of electric vehicles(EVS) was designed.Firstly,based on the analysis of basic structure and working principle,the mathematic models were established on the transmission ratio,slipping ratio,transferring torsion and transmission efficiency; Secondly,Transmission characteristics of the TIVT were analyzed and calculated using ADAMS software.The calculation results show that:the export torsion varies with sway angle of steer ring as the import torsion is fixed.The transmission efficiency of TIVT is large when the motion of driving parts is pure-rolling or the slipping ratio is less.The efficiency could be reached more than 99% by rational designing.Theoretically,the driving distance of EVS matched with TIVT could be increased.
