The invention provides a method for adjusting a large rotation angle of a Macpherson suspension. The Macpherson suspension comprises a steering knuckle, an REPS steering gear and a steering pull rod connecting the steering knuckle and the REPS steering gear, the steering knuckle comprises a main pin connecting part, a steering arm, a main pin bearing pin and a steering knuckle, and the main pin bearing pin is sleeved with the main pin connecting part; two points, matched with the kingpin bearing pin, of the kingpin connecting part are selected as an upper kingpin point and a lower kingpin point respectively; selecting a point where the steering arm is matched with the steering pull rod as a pull rod outer point; when the wheel track of the vehicle is increased, the lower point of the main pin is adjusted to move inwards in the width direction of the vehicle body; the pull rod outer point is adjusted to move downwards in the height direction of the vehicle body. According to the adjusting method, the number of hard points is small, the turning angle can be increased, and meanwhile the steering resisting moment is reduced.
本申请提供一种调节麦弗逊悬架大转角的方法。麦弗逊悬架包括转向节、REPS转向器以及连接转向节与REPS转向器的转向拉杆,所述转向节包括主销连接部、转向臂、主销轴承销与羊角,所述主销连接部套设于所述主销轴承销的外侧;选取所述主销连接部与所述主销轴承销配合的两个点分别为主销上点及主销下点;选取所述转向臂与所述转向拉杆配合的点为拉杆外点;车辆轮距增大时,沿车身宽度方向调整所述主销下点向内移动;沿车身高度方向调整所述拉杆外点向下移动。本申请的调节方法涉及的硬点少,即可实现转角的增大,同时减小了转向阻力矩。
