Abstract
The invention discloses a gear shifting guide shaft assembly of a two-gear automatic transmission. The gear shifting guide shaft assembly of the two-gear automatic transmission comprises a gear shifting guide shaft, a first bearing, a gear shifting worm-wheel shaft gear, a gear shifting guide shaft worm, a second bearing and a torsion damper assembly. The torsion damper assembly comprises a left damper cover, a right damper cover and a torsion damper check ring which are sequentially arranged from left to right. At least three cylindrical helical springs are evenly and circumferentially distributed and installed in installation cavities correspondingly arranged in the right damper cover through pre-tightening force. The left damper cover is buckled together with the torsion damper check ring after crossing the right damper cover. The outer diameter of each cylindrical helical spring is larger than the depth of the corresponding installation cavity so that 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. When outer teeth of the gear shifting worm-wheel shaft gear are worn, a gap generated due to wear can be automatically compensated for, and gapless meshing between the gear shifting worm-wheel shaft gear and a shift lever is achieved.
