Title (EN) HIGH PERFORMANCE SYNCHRONOUS TRANSMISSION
(FR) TRANSMISSION SYNCHRONE À HAUT RENDEMENT
Abstract:
(EN) A high performance synchronous transmission (1) to be used aboard a motorcycle for transmitting the motion generated by an engine to a driving wheel, between a crankshaft (2) and a hub shaft parallel therebetween and perpendicular to the median plane of the motorcycle, having a primary shaft (51) of mechanical gearbox equipped with a primary gearwheel (60), and a pair of secondary gearwheels (52, 53) equipped with one or more secondary shafts for transmitting the motion to a hub shaft (75), wherein the primary shaft (51) receives the motion through a driven pulley (17) which receives the motion by a driving pulley (13) connected to the crankshaft (2), an input clutch (40) being provided on the primary shaft.
(FR) L'invention concerne une transmission synchrone à haut rendement (1) destinée à être utilisée à bord d'une motocyclette afin de transmettre le mouvement produit par un moteur à une roue motrice, entre un vilebrequin (2) et un arbre de moyeu parallèles entre eux et perpendiculaires au plan médian de la motocyclette, la transmission comportant un arbre primaire (51) de boîte de vitesse mécanique muni d'une roue dentée primaire (60), et une paire de roues dentées secondaires (52, 53) munies d'au moins un arbre secondaire destiné à transmettre le mouvement à un arbre de moyeu (75), l'arbre primaire (51) recevant le mouvement par l'intermédiaire d'une poulie menée (17) qui reçoit le mouvement au moyen d'une poulie motrice (13) reliée au vilebrequin (2), un embrayage d'entrée (40) étant agencé sur l'arbre primaire.
