Abstract
The invention discloses a torsion shock absorber applied to a gear shifting guide shaft assembly. The torsion shock absorber applied to the gear shifting guide shaft 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. At least three cylindrical helical springs evenly and circumferentially distributed are installed in installation cavities correspondingly arranged in the right shock absorber cover through pre-tightening force. Lightening holes are further arranged between the installation cavities and a guide shaft. The left shock absorber cover passes across the right shock absorber cover and then is buckled with the torsion absorber check ring. 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. 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 wheel. Inner teeth are arranged on the left side of the left shock absorber cover to be engaged with a gear shifting worm wheel shaft gear. 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.
