The invention relates to the technical field of automobile steering mechanisms, and discloses an automobile four-wheel independent steering mechanism based on motor driving, which comprises an automobile body and a wheel; a fixed shaft is fixedly mounted in the middle of the wheel, a driving motor is movably mounted at the bottom of the automobile body, and a movable shaft of the driving motor isfixedly connected with a transmission shaft; the right end of the transmission shaft is fixedly connected with a fixed ball cage type universal joint through a spline, and the fixed ball cage type universal joint is fixedly connected with the left end of the fixing shaft on the wheel through a spline. Through the arrangement of the driving motor and the ball cage, power transmission and steering of the wheel are relatively independent; when the wheel steers within the range of 0-45 degrees, the driving motor and an automobile body are kept static relatively, shaking of automobile parts is reduced, and the stability of the automobile is improved; meanwhile, the driving motor is arranged in the automobile body, the problem that external gravel collides with the driving motor and cause damageto the driving motor is solved, and therefore, the protection performance of the driving motor can be improved.

    本发明涉及汽车转向机构技术领域,且公开了一种基于电机驱动的汽车四轮独立转向机构,包括车身和车轮,所述车轮的中部固定安装有固定轴,所述车身底部活动安装有驱动电机,所述驱动电机的活动轴固定连接有传输轴,所述传输轴的右端通过花键固定连接有固定型球笼式万向节,所述固定型球笼式万向节与车轮上固定轴的左端通过花键固定连接。通过驱动电机和球笼的设置,将车轮的动力传输与转向进行相对独立,在车轮进行0‑45度范围内的转向时,驱动电机与车身保持相对静止,减少汽车零部件的晃动,增加汽车的平稳性,同时将驱动电机置于车身内部,防止外界砂石撞击驱动电机,导致驱动电机损坏,有利于提高对驱动电机的防护性。
