Abstract:

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.

Key words:torque measurement; electric wheel drive; force sensor; eccentric sleeve
