摘要 提出了基于齿轮传动特征和力传感原理的电动汽车轮边减速驱动系统转矩检测新方法,旨在为分布式驱动电动汽车轮边电机的控制提供实时、精确的输出转矩反馈信息.阐明了布置于轮边齿轮减速器轴承端部的偏心套式转矩检测机构的工作原理,根据齿轮机构传力分析,导出轮边电机转矩检测公式;通过仿真分析、样机试制和试验测试,验证所述转矩检测方法的可行性和检测精度的准确性.该转矩检测方法有利于电动汽车驱动电机的高效控制,改善电动汽车的能源利用率和行驶性能. A novel torque measurement method of electric wheel drive system for electric vehicles was proposed based on gear transmission and force sensor to provide real time and accurate feedback information of output torque for drive motor control of distributed electric wheel drive vehicles. The working principle of eccentric sleeve torque measurement mechanism was presented to set up at the end of transmission bearing,and a torque measurement equation of wheel drive motor was deduced by force analysis of transmission mechanism. Then,by simulation analysis,prototype manufacturing and experimental measurement,the feasibility and accuracy of the torque measurement method were verified.This torque measurement method is beneficial to control drive motor in electric vehicles and can improve the energy utilization and driving performance of electric vehicles.
