Abstract
The invention discloses a torsion shock absorber assembly which comprises a left shock absorber cover, a right shock absorber cover and a torsion shock absorber check ring. The left shock absorber cover, the right shock absorber cover and the torsion shock absorber check ring are sequentially arranged from left to right. At least three cylindrical screw springs circumferentially and evenly distributed are arranged in mounting cavities correspondingly formed in the right shock absorber cover through pretightening force. The left shock absorber cover crosses over the right shock absorber cover and then is buckled with the torsion shock absorber check ring. The outer diameter of the cylindrical screw springs is larger than the depth of cavity bodies of the mounting cavities so that when left cavity bodies and right cavity bodies rotate relative to the mounting cavities, the cylindrical screw springs can be compressed by the side walls of the left cavity bodies and the side walls of the right cavity bodies. Spline teeth are arranged on the right side of the right shock absorber cover and used for being connected with a gear shifting guide shaft worm gear, and inner teeth are arranged on the left side of the left shock absorber cover and used for being engaged with a gear shifting worm shaft gear. When outer teeth of the gear shifting worm shaft gear are abraded, automatic compensation can be carried out on clearances generated by abrasion, and no-clearance meshing of the gear shifting worm shaft gear and a gear shifting lever is achieved.
