The invention relates to a non-independent suspension self-adaptive steering trapezoid. The trapezoid comprises a left trapezoid arm, a right trapezoid arm, a front beam and a self-adaptive steering tie rod, wherein the left trapezoidal arm and the right trapezoidal arm are mounted on a steering knuckle, the steering knuckle is mounted on the front beam through a revolute pair, two ends of the self-adaptive steering tie rod are respectively connected with the left trapezoidal arm and the right trapezoidal arm through the revolute pairs, the self-adaptive steering tie rod is a length-adjustablesteering tie rod and comprises a cylinder body and a push rod, the cylinder body is connected with the push rod through a sliding pair, and linear telescopic movement of the push rod relative to thecylinder body is driven by a servo motor. The control method of the non-independent suspension self-adaptive steering trapezium comprises steps of during automobile steering, a deflection angle of theleft or right trapezoidal arm relative to the front beam is measured in real time through a sensor, in order to meet the requirement that the trapezoidal arm on the other side deflects according to an ideal angle relative to the front beam, the ideal length of the self-adaptive steering tie rod is obtained through calculation according to the Ackerman steering principle, and then the length of the self-adaptive steering tie rod is controlled and adjusted through the servo motor, so two steering wheels roll purely for turning.

    一种非独立悬架自适应转向梯形包含左梯形臂、右梯形臂、前梁、自适应转向横拉杆,所述左、右梯形臂安装在转向节上,转向节通过转动副安装到前梁上,所述自适应转向横拉杆的两端通过转动副分别与左、右梯形臂连接,自适应转向横拉杆为长度可调的转向横拉杆,包含缸体、推杆,所述缸体与推杆通过移动副连接,推杆相对缸体的直线伸缩运动由伺服电机驱动。所述非独立悬架自适应转向梯形的控制方法为:当汽车转向时,通过传感器实时测得左或右梯形臂相对前梁偏转角度,为满足另一侧梯形臂相对前梁按理想角度偏转,依据阿克曼转向原理,通过计算获得自适应转向横拉杆的理想长度,再通过伺服电机控制调节自适应转向横拉杆的长度,使两转向轮纯滚动过弯。
