<p>The device has an assistance spring (11) that is supported against pivots (8, 9). The spring is wound around rods (12a, 12b) fixed on eyelets (13) engaged to the pivots respectively. The spring is maintained on the pivots by spring retaining rings. The spring is placed parallel to a force transmission chain of a passage command for releasing energy when a passage command axle (1) is spaced from its dead center position to an engaged gear position. The spring accumulates energy by being compressed during the return of the axle to the dead center position.</p> |
