Abstract
La présente invention concerne un mécanisme de commande verrouillable d'un inverseur constitué par une tringlerie 9, qui s'étend entre un levier 7 de sélection manuelle du sens de marche et ledit dispositif d'inversion, et qui comporte un moyen de pilotage 27 d'un distributeur 22 de commande d'un dispositif embrayage 5, placé entre un variateur et l'inverseur. Selon l'invention, un dispositif de maintien du distributeur 22 dans sa position stable est constitué par au moins un organe 29 escamotable, commandé en déplacement par un détecteur 37 de la condition de roulage du véhicule, ledit organe 29 coopérant lorsque le roulage est effectif, avec le moyen de pilotage 27 susdit pour l'immobiliser et constituer un moyen de verrouillage de la tringlerie. Application à l'industrie automobile.
