Abstract

MECANISME COMPRENANT UN ENGRENAGE REDUCTEUR PLANETAIRE DANS LEQUEL UN PREMIER ELEMENT COMPOSANT EST RELIE AU MOTEUR, UN SECOND ELEMENT COMPOSANT EST RELIE AU DISPOSITIF DE TRANSMISSION A FRICTION, ET UN TROISIEME ELEMENT EST RELIE A DES ROUES ET A UN ENGRENAGE D'INVERSION DE MARCHE. MECANISME CARACTERISE EN CE QUE L'ENGRENAGE D'INVERSION DE MARCHE EST DISPOSE INDEPENDAMMENT, SANS L'UTILISATION HABITUELLE DU DISPOSITIF DE TRANSMISSION A FRICTION NI DE L'ENGRENAGE PLANETAIRE, COMME UN MECANISME DE CHANGEMENT DE VITESSE A INVERSION DE MARCHE, LE CHANGEMENT DE VITESSE DE MARCHE AVANT COMPRENANT L'ETAT D'ARRET ETANT ASSURE PAR COOPERATION ENTRE LE DISPOSITIF DE TRANSMISSION PROGRESSIF A FRICTION ET L'ENGRENAGE REDUCTEUR PLANETAIRE, TANDIS QUE L'INVERSION DE MARCHE AVANTARRIERE EST ASSUREE PAR L'ENGRENAGE D'INVERSION DE MARCHE. DISPOSITIF APPLICABLE A UN TRACTEUR AGRICOLE.
