Abstract

La présente invention concerne un appareil (1) qui comprend un levier de vitesses (non représenté) relié à une unité de servo-commande (4) par l'intermédiaire d'un arbre d'entrée rotatif (3) et un élément de levier (11). L'appareil (1) comprend un arbre sélecteur de vitesse rotatif (2) et des servo-moyens (non représentés) pour exécuter un mouvement mécanique de l'arbre sélecteur de vitesse (2). L'arbre sélecteur de vitesse (2) et l'arbre d'entrées sont rotatifs autour d'un axe longitudinal (8). L'appareil (1) comprend en outre des moyens de rétroaction sensoriels, moyennant quoi, durant l'utilisation, les moyens de rétroaction sensoriels indiquent à l'opérateur un emplacement relatif d'un levier de vitesses par la mise à disposition d'une force variable qui résiste au mouvement du levier de vitesses. Les moyens de rétroaction sensoriels comprennent un mécanisme de cliquet (10) disposé entre le levier de vitesses et l'unité de commande (4). Le mécanisme de cliquet (10) comprend un élément de levier mobile (11) fixé à l'arbre d'entrée (3) et un élément d'indexage (14) sous forme de ressort de compression (14) et un palier à billes (17). L'extrémité distale de l'élément de levier (11) est formée avec une série de trois cliquets (12) agencés dans un arc. L'élément de levier (11) pivote autour de l'axe (8) par l'intermédiaire d'une force de rotation dirigée à travers une liaison à goupille inférieure (5). La force de rotation émane du déplacement du levier de vitesses par l'opérateur. Le palier à billes (17) est poussé vers l'élément de levier (11) par le ressort de compression (15). Le palier à billes (17) est en contact coulissant avec les cliquets (12) et peut être reçu par les cliquets (12) dans une action à fixation immédiate. Un mouvement de pivotement de l'élément de levier (11) force l'arbre d'entrée (3) à pivoter autour de l'axe (8).
