Title
(EN) MOTORCYCLE, OF THE SCOOTER TYPE OR WITH CHAIN DRIVE, COMPRISING A QUADRILATERAL REAR SUSPENSION
(FR) MOTOCYCLETTE, DE TYPE TROTTINETTE OU À ENTRAÎNEMENT À CHAÎNE, COMPRENANT UNE SUSPENSION ARRIÈRE QUADRILATÉRALE
Abstract
(EN)
The present invention relates to a motorcycle (1), of the scooter type or provided with an at least partially chain drive, with a quadrilateral-configured suspension. The motorcycle comprises a mechanical drive to transfer a torque generated by said motor (100) to a rear wheel (13). Such a drive comprising at least a first drive element (51) and a first drive unit to rotate said first drive element (51). The first drive element (51) is hinged to a swingarm (21) of the rear suspension which connects the rear wheel (13) to the frame (12). According to the invention, the mechanical drive comprises a second drive unit for transmitting the motion from the first drive element (51) to the rear wheel (13), wherein such a second drive unit comprises at least a second drive element (52) which is rotationally integral with said rear wheel (13) and at least one intermediate drive element (53) for ransmitting the motion from the first drive element (51) to the second drive element (52). According to the invention, the rear suspension further comprises a connecting rod (22) hinged to the swingarm (21), a rod (23) hinged to the connecting rod (22) by means of a third connection axis (33) and to the frame (12) by means of a fourth connection axis (34). The connecting rod (22) supports the intermediate drive element of the second drive unit.
(FR)
La présente invention concerne une motocyclette (1) de type trottinette ou pourvue d'un entraînement au moins partiellement à chaîne, avec une suspension à configuration quadrilatérale. La motocyclette comprend un entraînement mécanique pour transférer un couple généré par ledit moteur (100) à une roue arrière (13). Un tel entraînement comprend au moins un premier élément d'entraînement (51) et une première unité d'entraînement pour faire tourner ledit premier élément d'entraînement (51). Le premier élément d'entraînement (51) est articulé sur un bras oscillant (21) de la suspension arrière qui relie la roue arrière (13) au cadre (12). Selon l'invention, l'entraînement mécanique comprend une seconde unité d'entraînement pour transmettre le mouvement du premier élément d'entraînement (51) à la roue arrière (13), une telle seconde unité d'entraînement comprenant au moins un second élément d'entraînement (52) qui est solidaire en rotation de ladite roue arrière (13) et d'au moins un élément d'entraînement intermédiaire (53) pour transmettre le mouvement du premier élément d'entraînement (51) au second élément d'entraînement (52). Selon l'invention, la suspension arrière comprend en outre une tige de liaison (22) articulée sur le bras oscillant, une tige (23) articulée à la tige de liaison (22) au moyen d'un troisième axe de liaison (33) et au cadre (12) au moyen d'un quatrième axe de liaison (34). La tige de liaison (22) supporte l'élément d'entraînement intermédiaire de la seconde unité d'entraînement.
