Abstract
The invention discloses a shock absorber for a gear-shifting guide shaft assembly. The shock absorber comprises a shock absorber left cover, a shock absorber right cover and a torsion shock absorber check ring which are sequentially arranged from left to right. At least three cylindrical helical springs which are evenly distributed in the circumferential direction are installed in installation cavities correspondingly formed in the shock absorber right cover through pre-tightening force. The shock absorber left cover and the torsion shock absorber check ring are buckled together through clamping buckles and clamping grooves. The outer diameter of the cylindrical helical springs is larger than the depth of the installation cavities, and therefore when left cavities and right cavities rotate relative to the installation cavities, the side walls of the left cavities and the side walls of the right cavities can compress the cylindrical helical springs. Spline teeth are arranged on the right side of the shock absorber right cover and used for being connected with a gear-shifting guide shaft worm wheel. Internal teeth are arranged on the left side of the shock absorber left cover and used for being meshed with a gear-shifting worm wheel shaft gear. When external teeth of the gear-shifting worm wheel shaft gear are worn, clearance generated by wear can be automatically compensated for, and therefore zero-clearance meshing between the gear-shifting worm wheel shaft gear and a gear-shifting lever is achieved.
