Abstract

A.BOITE DE CHANGEMENT DE VITESSES SYNCHRONISEE POUR VEHICULES AUTOMOBILES OU DEUX GROUPES DE MECANISMES PEUVENT ETRE CONNECTES PAR UN EMBRAYAGE PLACE SUR LE FLUX DE FORCE. B.L'EMBRAYAGE EST PLACE DE FACON TELLE QUE L'ENERGIE D'INERTIE TOTALE MOYENNE DES MASSES QUI SONT EN AVANT DE L'EMBRAYAGE EST AU MOINS APPROXIMATIVEMENT EGALE A CELLE DES MASSES DE L'AUTRE GROUPE DE MECANISMES. C.CETTE DISPOSITION DIMINUE BEAUCOUP L'EFFORT A FOURNIR POUR PASSER LES VITESSES.A. SYNCHRONIZED GEAR CHANGE BOX FOR MOTOR VEHICLES OR TWO GROUPS OF MECHANISMS CAN BE CONNECTED BY A CLUTCH PLACED ON THE FORCE FLOW. B. THE CLUTCH IS LOCATED SUCH AS THE AVERAGE TOTAL INERTIA ENERGY OF THE MASSES BEFORE THE CLUTCH IS AT LEAST APPROXIMATELY EQUAL TO THE MASS OF THE OTHER MECHANISM GROUP. C. THIS ARRANGEMENT SIGNIFICANTLY REDUCES THE EFFORT TO UPGRADE.
