摘要

The mechanism of change gears to prevent unintentional uncoupling of gear in a gearbox of the vehicle hired. The present invention relates to a mechanism for preventing unintentional disengagement plan, comprising a lever of a gearbox (7), which is mounted to pivot around a first pivot point (9) between two end positions.A first end (10) of a bar (4) is alternately fixed to the lever of a gearbox (7) at a first distance from said first pivot point (9) of the lever of a gearbox (7).A second end (11) of said bar (4) is alternately fixed to a lever main (1) at a second distance from a point of articulation of a major lever (3).The first end (12) of an action spring (5) is alternately fixed to the lever main (1) at a pivot point (14) in a third distance from said point of articulation of a major lever (3).A second end (13) of the appeal of spring (5) is alternately fixed to a second point of articulation (6) in a fixed position relatively to the first point of articulation (9) and the articulation point of the main lever (3).
