Title (EN) COUNTERBALANCING SYSTEM FOR NUTATIONAL TRACTION DRIVE TRANSMISSIONS
(FR) SYSTEME DE CONTRE EQUILIBRAGE POUR DES TRANSMISSIONS DE TRACTION DE NUTATION
Abstract: front page image
(EN)A counterbalancing system for continuously variable torque transmissions of the type in which one of two working bodies (16, 28), between which torque is transmitted by rolling friction, undergoes a nutational movement to generate an inertial couple which is variable with an output speed varying component of the transmission. The system includes a pair of variably positioned counterweights (88, 90) connected for movement directly with the speed varying mechanism of the transmission in a manner such that at least the variable component of the inertial couple is substantially counterbalanced for all speed ratios of the transmission.
(FR)Systeme de contre equilibrage pour des transmissions de couple a variation continue du type dans lequel un des deux corps (16, 28) en fonctionnement, entre lesquels le couple est transmis par friction de roulement, subit un mouvement de nutation de facon a engendrer un couple d'inertie variant avec une composante de la transmission qui fait varier la vitesse de sortie. Le systeme comprend une paire de contrepoids (88, 90) positionnes de facon variable dont le mouvement est lie directement au mecanisme de variation de vitesse de la transmission de telle sorte qu'au moins la composante variable du couple d'inertie soit considerablement contre equilibree pour tous les rapports de vitesse de la transmission.
