The invention relates to a double-wheel steering drive axle, a steering system, a steering method and an automobile, the double-wheel steering drive axle comprises a drive motor mounting steering seat, outer side wheels, inner side wheels, a first drive motor, a second drive motor and a clutch device, and the inner side wheels are arranged on the inner sides of the outer side wheels side by side to form double wheels; the upper end, provided with the steering base, of the driving motor is used for being rotatably connected to the suspension structure around a vertical axis. According to the double-wheel steering drive axle, the first drive motor and the second drive motor can control the rotating speed of the outer side wheel and the rotating speed of the inner side wheel correspondingly, so that the rotating speed difference is formed between the outer side wheel and the inner side wheel, and the rotating speed difference enables the ground to generate unequal friction counterforce on the tire treads of the inner side wheel and the outer side wheel; and then steering torque enabling the driving motor mounting steering seat to rotate around the vertical axis is generated, and double-wheel steering is completed.

    本申请涉及一种双车轮转向驱动桥、转向系统、转向方法及汽车,该双车轮转向驱动桥包括驱动电机安装转向座、外侧车轮、内侧车轮、第一驱动电机、第二驱动电机及离合装置,所述内侧车轮并排设置在所述外侧车轮的内侧以构成双车轮,所述驱动电机安装转向座的上端用于绕一竖直轴线可转动地连接在悬架结构上。本申请的双车轮转向驱动桥,第一驱动电机与第二驱动电机能够分别控制外侧车轮与内侧车轮的转速,以使得外侧车轮与内侧车轮形成转速差,转速差使得地面对内侧车轮及外侧车轮的轮胎胎面产生不相等的摩擦反力,进而产生使驱动电机安装转向座绕竖直轴线旋转的转向力矩,完成双车轮转向。
