Abstract

LE VARIATEUR COMPREND DEUX PAIRES DE POULIES CONIQUES 3, 4, 5, 6, L'UNE 4, 5 DE CHAQUE PAIRE POUVANT SE DEPLACER AXIALEMENT SOUS CONTROLE D'UNE CHAMBRE HYDRAULIQUE 7, 8 POUR REGLER LE RAPPORT DE TRANSMISSION. LES CHAMBRES 7, 8 SONT RELIEES A UN DISTRIBUTEUR 13 AYANT UN TIROIR ARTICULE A UN LEVIER 20 DONT UNE EXTREMITE SUIT LES DEPLACEMENTS AXIAUX DE L'UNE DES POULIES MOBILES 4, 5, ET L'AUTRE EXTREMITE EST REGLABLE POUR SELECTIONNER LE RAPPORT DE TRANSMISSION. UNE VALVE D'ASSERVISSEMENT 17 EST RELIEE A LA SORTIE DE DECHARGE DU DISTRIBUTEUR 13 ET SOUMISE A LA PRESSION REGNANT DU COTE SECONDAIRE DU VARIATEUR. LA POUSSEE SUR LA BILLE 24 DE LA VALVE 17 EST EXERCEE PAR UNE BOBINE 22 PARCOURUE PAR UN COURANT QUI EST FONCTION DU COUPLE TRANSMIS PAR LE VARIATEUR. UTILISATION DANS LES TRANSMISSIONS EXPOSEES AUX A-COUPS.
