The invention belongs to the technical field of electric vehicle chassis, and particularly relates to an independent steering system with a steering motor arranged on an equal-length double-trailing-arm suspension steering knuckle. The system comprises an upper longitudinal arm, a lower longitudinal arm, a ball stud, a steering motor, a steering knuckle, a hub motor assembly and the like. The upper longitudinal arm and the lower longitudinal arm have the same length, one end is connected with a vehicle body, the other end is connected with a knuckle through a spherical hinge, a shell of the steering motor is fixed to a motor support, an output shaft of the steering motor is connected with the knuckle, and the axis of the output shaft of the steering motor coincides with the axis of the main pin. The advantage that the wheel positioning parameters of the equal-length double-trailing-arm suspension are not changed when wheels jump is combined, the steering motor is directly arranged on the axis of the main pin, and it is guaranteed that steering torque can be completely and effectively used for driving steering while the minimum steering driving chain is achieved; important referencesignificance is realized on the research and development of the steering performance of the wheel hub motor driven vehicle and the application of the double-trailing-arm independent suspension.

    本发明属于电动车底盘技术领域,具体涉及一种转向电机置于等长双纵臂悬架转向节上的独立转向系统。该系统包括上纵臂、下纵臂、球头销、转向电机、转向节和轮毂电机总成等。上纵臂和下纵臂具有一样的长度,一端与车体连接,一端通过球铰跟转向节连接,转向电机的外壳固定在电机支座上,转向电机的输出轴跟转向节连接,转向电机输出轴的轴线与主销轴线重合。本发明结合了等长双纵臂悬架在车轮跳动时具有车轮定位参数不改变的优点,直接将转向电机置于主销轴线上,具有最少转向驱动链的同时保证了转向力矩可全部有效地用来驱动转向,对轮毂电机驱动车辆的转向性能的研发以及双纵臂独立悬架的应用具有重要借鉴意义。
