A method for optimizing the steering sensitivity of a vehicle steering system comprises a vehicle to be assembled, the vehicle steering system comprises a steering wheel, and the steering wheel is connected with a steering gear after sequentially passing through a steering column and an intermediate shaft, and the method comprises the following steps that the installation angle of the intermediate shaft on the steering column is adjusted; when the steering wheel is in the steering neutral position, the rotation speed ratio of the intermediate shaft is located at the peak value of the ratio, and the installation angle is the rotation angle of a joint fork of the intermediate shaft relative to the steering column; by adjusting the rotation angle of the joint fork of the intermediate shaft relative to the steering column, under the condition that hardware of the steering system is not changed, namely redesign and manufacturing of parts are not involved, the transmission ratio of the steering system is minimum, and the steering sensitivity is maximum at the moment when the steering wheel is in the steering neutral position; the sensitivity of the steering wheel in a small steering angle range when the steering wheel is in a steering neutral position can be effectively improved, so that an automobile can effectively carry out urgent danger avoiding in the high-speed running process, and traffic accidents are effectively avoided.

    一种用于优化车辆转向系统的转向灵敏度方法,包括待装配的车辆,车辆的转向系统包括方向盘,方向盘依次经转向管柱、中间轴后与转向器连接,该方法包括以下步骤:调整中间轴在转向管柱上安装角度,并使方向盘处于转向中位时中间轴的转速比位于该比值的峰值处,其中,安装角度为中间轴的节叉相对转向管柱的旋转角度;通过调整中间轴的节叉相对转向管柱的旋转角度,在不改变转向系统硬件的情况下,即不涉及零件的重新设计和制造,使方向盘处于转向中位时,转向系统的传动比最小,此时转向灵敏度最大;可以有效提高方向盘处于转向中位时小转向角度范围内的灵敏度,使得汽车在高速行驶过程中有效进行紧急避险,从而有效避免交通事故的发生。
