摘要： The invention relates to a gear shift device for a mobility vehicle, comprising: —a selection shaft in which a shuttle and a worm are arranged, —at least two input pinions arranged to rotate freely about the selection shaft, —at least two output pinions coupled in rotation with a hollow shaft, —a gear shift actuator arranged to move the shuttle along the worm between at least two positions, and to engage a selected gear ratio, —at least two pawls arranged on the selection shaft, each pawl being associated with a lifting device for lifting the pawl via the shuttle, and to engage the gear ratio selected via the input and output pinions, the device comprising a radial blocking system, which is formed in one piece, for keeping all the pawls in place on the selection shaft.
