A precise steering Ackerman steering mechanism is used for adjusting rotation angles of a left front wheel and a right front wheel of a vehicle and comprises the left front wheel installed on a left suspension swing arm of the vehicle, the right front wheel installed on a right suspension swing arm of the vehicle, the left front wheel connected with a left steering knuckle arm, and the right front wheel connected with a right steering knuckle arm. A transverse pull rod is connected between the left steering knuckle arm and the right steering knuckle arm, a steering gear is arranged on the transverse pull rod, the steering gear is connected with a steering wheel of the vehicle through a power-assisted steering mechanism, and a left transverse pull rod length differential adjusting device and a right transverse pull rod length differential adjusting device are further arranged on the transverse pull rod. The lengths of the left tie rod and the right tie rod can be automatically adjusted through the ECU when an automobile turns, accurate Ackerman steering is achieved, and sliding and friction of front wheels during turning are reduced. And by adjusting the lengths of the left and right tie rods, the functions of changing the steering ratio and increasing the tire lateral deviation force can be achieved, and the operation stability and the braking effect during vehicle running are improved.

    一种精准转向的阿克曼转向机构,用于调节车辆的左前轮和右前轮的转动角度,包括左前轮安装在车辆的左悬架摆臂上,右前轮安装在车辆的右悬架摆臂上,左前轮与左转向节臂连接,右前轮与右转向节臂连接,左转向节臂和右转向节臂之间连接有横拉杆,横拉杆上设有转向器,转向器通过转向助力机构与车辆的方向盘连接,横拉杆上还设有左横拉杆长度差动调整装置和右横拉杆长度差动调整装置,通过ECU电子控制单元能够在汽车转弯行驶时自动调节左右横拉杆长度,实现精准的阿克曼转向,减小前轮在转弯行驶时的滑动与摩擦。并且通过调节左右横拉杆的长度,可以实现可变转向比以及增大轮胎侧偏力的功能,提高车辆行驶时的操纵稳定性和制动效果。
