The working principle of rack and pinion telescopic fork is briefly introduced.In order to make the meshing points of the rack and pinion on the telescopic fork accurately mesh and prevent the interference of gear teeth,calculations and virtual prototype tests were performed in conjunction with Wolfram Mathematica,Solidworks and AutoCAD software.Based on the principle derivation,a method capable of accurately assembling the rack and pinion is proposed,and the corresponding calculation method and case are given,which solves the problem of assembly precision of closed rack and pinion.This provides a basis for the actual assembly of rack and pinion telescopic fork.
