Abstract
The invention discloses a gear shifting guide shaft mechanism preventing a gear shifting worm wheel shaft gear from losing efficacy after the gear shifting worm wheel shaft gear is abraded. The gear shifting guide shaft mechanism comprises a gear shifting guide shaft, a gear shifting worm wheel shaft gear, a gear shifting guide shaft worm wheel and a torsion shock absorber assembly. The torsion shock absorber assembly comprises a left shock absorber cover, a right shock absorber cover and a torsion shock absorber check ring arranged sequentially from left to right. Cylindrical helical springs evenly and circumferentially distributed are installed in installation cavities correspondingly arranged in the right shock absorber cover through pre-tightening force. The left shock absorber cover and the shock absorber check ring are buckled together through a buckle and a clamping groove. The outer diameter of the cylindrical helical springs is larger than the depth of the installation cavities so that when a left cavity and a right cavity rotate relative to the installation cavities, the lateral walls of the left cavity and the right cavity can compress the cylindrical helical springs. When outer teeth of the gear shifting worm wheel shaft gear are abraded, gaps caused by abrasion can be automatically compensated, and seamless engagement between the gear shifting worm wheel shaft gear and a gear shifting rod is realized.
