Title (EN) CONTINUOUSLY VARIABLE TRANSMISSION
(FR) TRANSMISSION À VARIATION CONTINUE
(KO) 무단 변속기
Abstract:
(EN) The present invention relates to a continuously variable transmission comprising: a hollow driving shaft and a hollow driven shaft having a first and a second slot portion having a plurality of first and second slots; a pair of driving disks and driven disks having a plurality of first and second key grooves recessed in curved shapes along the radial direction; a plurality of first and second keys movably coupled to the first and second key grooves; a first and a second interval maintaining portion comprising a first and a second guide disk having a plurality of first and second guide grooves for guiding movements of the plurality of first and second keys, and a first and a second spacer that support the first and second guide disks, have a plurality of first and second profiles on the inner periphery thereof so as to correspond to the plurality of first and second slots and to be recessed in curved shapes along the longitudinal direction of the driving shaft, and maintain intervals between the pair of driving disks and driven disks; a power transfer member for connecting the pair of driving disks and driven disks to each other and transferring rotational force from the driving disks to the driven disks; and a transmission adjustment portion having a first and a second locking pins that penetrate the first and second slots and are movably coupled to the first and second profiles, and making adjustments such that an increase/decrease in the radius of rotation of the plurality of first keys is inversely proportional to an increase/decrease in the radius of rotation of the plurality of second keys.
(FR) La présente invention concerne une transmission à variation continue comprenant : un arbre menant creux et un arbre mené creux comportant une première et une seconde parties à fentes dotées d'une pluralité de premières et secondes fentes ; une paire de disques menants et de disques menés comportant une pluralité de premières et secondes rainures de clavette évidées en formes incurvées le long de la direction radiale ; une pluralité de premières et secondes clavettes accouplées mobiles aux premières et secondes rainures de clavette ; une première et une seconde parties de maintien d'intervalle comprenant un premier et un second disques de guidage comportant une pluralité de premières et secondes rainures de guidage destinées à guider les déplacements de la pluralité de premières et secondes clavettes, et un premier et un second éléments d'espacement destinés à porter les premier et second disques de guidage, comportant une pluralité de premiers et seconds profils sur leur périphérie interne afin de correspondre à la pluralité de premières et secondes fentes et d'être évidées en formes incurvées le long de la direction longitudinale de l'arbre menant, et maintenant des intervalles entre la paire de disques menants et de disques menés ; un élément de transfert de puissance destiné à relier la paire de disques menants et de disques menés l'une à l'autre et à transférer une force de rotation des disques menants aux disques menés ; et une partie de réglage de transmission comportant une première et une seconde broches de verrouillage destinées à pénétrer dans les première et seconde fentes et étant accouplées mobiles aux premier et second profils, et permettant d'effectuer des réglages de sorte qu'une augmentation/diminution du rayon de rotation de la pluralité de premières clavettes soit inversement proportionnelle à une augmentation/diminution du rayon de rotation de la pluralité de secondes clavettes.
