Title
(EN) DRIVEN PULLEY FOR A CONTINUOUSLY VARIABLE TRANSMISSION
(FR) POULIE MENÉE POUR UNE TRANSMISSION À VARIATION CONTINUE
Abstract
(EN)
The driven pulley (200) is part of a continuously variable transmission (CVT) (100). It includes a fixed sheave (210) and a movable sheave (214) having conical walls (212, 216) forming a drivebelt-receiving groove (218). The driven pulley (200) also includes at least two axially extending members (260) for providing a direct torque-transmitting engagement between the two sheaves (210, 214) while allowing a relative axial motion between them. An insert (310) is also affixed inside each passageway (262) to simplify the manufacturing process and reduce costs.
(FR)
La poulie menée (200) fait partie d'une transmission à variation continue (TVC) (100). Elle comprend une poulie fixe (210) et une poulie mobile (214) ayant des parois coniques (212, 216) formant une rainure de réception de courroie de transmission (218). La poulie menée (200) comprend également au moins deux éléments s'étendant axialement (260) pour fournir une prise directe de transmission de couple entre les deux poulies (210, 214) tout en permettant un mouvement axial relatif entre eux. Un insert (310) est également fixé à l'intérieur de chaque passage (262) pour simplifier le processus de fabrication et réduire les coûts.
