The invention relates to an electric power-assisted steering device of a double-front-axle vehicle, which comprises a steering assembly, wherein the steering assembly is used for applying a steering torque for changing the advancing direction of wheels to a wheel steering device; the power assisting assembly is connected with the steering assembly, and the power assisting assembly is used for applying power assisting torque for changing the advancing direction of the wheels; the sensor assembly, the steering assembly and the power assisting assembly are electrically connected with the control terminal, the sensor assembly is used for receiving steering information and sending the steering information to the control terminal, and the control terminal calculates power assisting data based on the steering information and sends the power assisting data to the power assisting assembly. A steering transition pull rod and a first transition middle arm are omitted, and the failure risks of transition pull rod bending and transition arm breakage are reduced; the hard connection of the first axle and the second axle is cancelled, the relation between the synchronization angle of the second front axle and Ackerman steering is independently controlled, the problem of tire abrasion and tire eating of the second axle of the double-front-axle vehicle is solved, the service life of steering components and tires can be greatly prolonged, and the driving safety is enhanced.

    本申请涉及一种双前轴车电动转向助力装置,转向组件,所述转向组件用于向车轮转向装置施加改变车轮的行进方向的转向扭矩;助力组件,所述助力组件与转向组件相连接,所述助力组件用于施加改变车轮行进方向的助力扭矩;传感器组件,所述传感器组件、转向组件和助力组件分别与控制终端电连接,所述传感器组件用于接收转向信息并发送至控制终端,所述控制终端基于转向信息计算助力数据并将助力数据发送至助力组件。取消转向过渡拉杆及第一过渡中间臂,降低过渡拉杆弯曲、过渡臂断裂的失效风险;取消一轴二轴硬连接,独立控制第二前轴同步角与阿克曼转向关系,解决双前轴车二轴磨胎吃胎问题,可以大幅提升转向部件及轮胎寿命,增强驾驶安全性。
