AI Technical Summary

Technical Problem

During the alignment process of existing intelligent steering systems, assembly errors can cause the nut to not be in the middle position of the lead screw, resulting in steering discrepancies and affecting driving feel.

Method used

Design a centering device for an intelligent steering gear, including a frame, a servo motor, a transmission mechanism, a floating mechanism, and a positioning seat. The servo motor drives the lead screw to rotate, and the floating mechanism and positioning seat ensure that the nut moves accurately to the center of the lead screw, calibrating the zero point of the torque sensor and eliminating steering discrepancies.

Benefits of technology

It effectively eliminates steering gaps, improves driving feel, and enhances centering efficiency, making it particularly suitable for the centering process of intelligent steering systems.
