AI Technical Summary
The existing steering column assembly friction pad structure is difficult to meet the driver's need for greater holding force, and it is also complex and costly to manufacture.
A friction pad assembly for the extension and retraction of a steering column is designed, comprising two sets of symmetrically arranged friction pads and gaskets, which are alternately coated with grease and set in a waist-shaped groove on the side plate of the steering column. The axial movement of the friction pad assembly is restricted by the arc surface of the waist-shaped groove, thereby increasing the friction area and holding force.
The increased friction of the steering column meets the requirement of greater holding force, simplifies the manufacturing process, and reduces costs.
