Friction and clearance are the typical non-linear factors that affect the mechanical properties of the electric steering gear.According to the servo model of the electric servo, the characteristics of the friction and the nonlinear factors of the clearance and their influence on the steering control are studied.A low-friction, Gap controllable steering gear transmission mechanism.The experimental results show that the new transmission mechanism can improve the frictional resistance of the traditional steering gear and the poor controllability of the gap and improve the precision and stability of the steering gear control.It is a good choice for the electric Servo servo system structural characteristics of research and control systems to provide the basis for the study.
