Title
(EN) MULTISTEP GEAR RATIO CHANGE DEVICE
(FR) DISPOSITIF DE CHANGEMENT DE RAPPORT D'ENGRENAGES EN PLUSIEURS ÉTAPES
Abstract
(EN)
The device comprises an input shaft (L6) engaged with a reducer formed as a multiengine gear drive and having three output links (Lll, L22, L33) arranged in parallel, for giving them different gear ratio and number of rotations, which are connected to planetary gear sets (Dl and D2); at that, each planetary gear set comprises a double-wheel sun gear (Z2) and central gear (Zl), wherein meshed with an internal teeth (Z3) of the sun gear and external teeth of the central gear are satellite gears (Z4), so connected to the latter by planet gear carriers (13 and 14) that upon rotation of the central gear (Zl), when the double-wheel sun gear (Z2) is stopped, the number of rotations of the output shaft (L5) is thrice different from the number of rotations of the output shaft (L5), when the double-wheel sun gear (Z2) rotates, while the central gear (Zl) is stopped; in addition, the multiengine gear drive consists of a cluster of constant-mesh gears located in a housing (7), friction disks (F), and a set of freewheeling and friction clutches (C).
(FR)
L'invention concerne un dispositif comprenant un arbre d'entrée (L6) en prise avec un réducteur formé en tant qu'entraînement à engrenages multimoteur et ayant trois liaisons de sortie (L11, L22, L33) agencées en parallèle, pour leur conférer un rapport d'engrenages et un nombre de rotations différents, qui sont reliées à des trains planétaires (D1 et D2) ; au niveau desquels, chaque train planétaire comprend un planétaire à double roue (Z2) et un engrenage central (Z1). En prise avec une denture intérieure (Z3) du planétaire et des dents externes de l'engrenage central se trouvent des satellites (Z4), reliés à ces derniers par des porte-satellites (13 et 14) de telle sorte que lors de la rotation de l'engrenage central (Z1), lorsque le planétaire à double roue (Z2) est arrêté, le nombre de rotations de l'arbre de sortie (L5) est trois fois différent du nombre de rotations de l'arbre de sortie (L5), lorsque le planétaire à double roue (Z2) tourne, tandis que l'engrenage central (Z1) est arrêté ; en outre, l'entraînement à engrenages multimoteur est constitué d'un groupe d'engrenages à engrènement constant situés dans un boîtier (7), de disques de friction (F), et d'un ensemble d'embrayages à roue libre et à friction (C).
