Title
(EN) DEVICE FOR THE SELECTIVE TRANSMISSION OF DRIVING TORQUES
(FR) DISPOSITIF DE TRANSMISSION SÉLECTIVE DE COUPLES D'ENTRAÎNEMENT
Abstract
(EN)
A device (100) for the selective transmission of torques, said device (100) comprising an inlet arranged to provide an inlet torque Q and comprising a transmission element (105) arranged to rotate with speed ω about a rotation axis x. The device (100) also comprises a predetermined number m of outlets arranged to express, respectively, outlet torques Ti, with i= 1,2,..., m each outlet comprising a receiving element (110,110',110a,110b,110a',110b') arranged to rotate with speed ϑi about said rotation axis x. The device (100) comprises then connection means (120) arranged to pass between a disengagement configuration and an engagement configuration. In the disengagement configuration the inlet is disengaged by each outlet in such a way that QTi and ω ≠ ϑi. In the engagement configuration the inlet is engaged to a number n of outlets, with 1≤nm, and the transmission element (105) is connected by friction to a number n of respective receiving elements (110,110',110a,110b,110a', 110b') in such a way that (Formula I) (I) and ω = ϑ1 = ϑ2 =... = ϑn.
(FR)
L'invention concerne un dispositif (100) permettant la transmission sélective de couples, ledit dispositif (100) comprenant une entrée agencée pour fournir un couple d'entrée Q et comprenant un élément de transmission (105) agencé pour tourner à une vitesse ω autour d'un axe de rotation x. Le dispositif (100) comprend également un nombre prédéfini m de sorties agencées pour exprimer, respectivement, des couples de sortie Ti, où i = 1,2, m, chaque sortie comprenant un élément de réception (110, 110', 110a, 110b, 110a', 110b') agencé pour tourner à une vitesse ϑi autour dudit axe de rotation x. Le dispositif (100) comprend en outre des moyens de liaison (120) conçus pour passer d'une configuration de désaccouplement à une configuration d'accouplement. Dans la configuration de désaccouplement, l'entrée est désaccouplée de chaque sortie de manière que QTi et ω ≠ ϑi. Dans la configuration accouplée, l'entrée est accouplée à un nombre n de sorties, où 1 ≤ n ≤ m, et l'élément de transmission (105) est relié par friction à un nombre n d'éléments de réception respectifs (110, 110', 110a, 110b, 110a', 110b') de manière que Q = ∑n i=1 T i et ω = ϑ1 = ϑ2 =... = ϑn.
