Abstract

Abstract: An independent drive mechanism that could achieve the large angle steering was presented． The maximum steering angle of the proposed mechanism was approaching ± 90℃． The drive motor and steering motor were arranged on the frame of the vehicle，which reduced the un-sprung mass and improved the ride performance of the electric car． The speed control algorithm for drive motor of the mechanism in different steering modes was analyzed theoretically． The 3D model of the mechanism was established by NX software． Finally，a case study relating the left front wheel was conducted to verify the correctness of the control algorithm through the simulation analysis．

Key words: vehicle engineering, large steering angle, independent drive, control algorithm, simulation analysis

摘要： 提出一种可实现大角度转向的电动汽车独立驱动机构，该机构的最大转向角接近± 90°，且驱动电机和转向电机均布置在车架上，降低了电动汽车的非簧载质量，提高了整车的行驶平顺性。对不同转向模式下的该机构驱动电机的转速控制算法进行了理论分析，并在NX 中建立了该机构的三维模型。最后，以左前轮为例，通过仿真分析验证了该控制算法的正确性。
