Title
(EN) POWER UNIT FOR STRADDLE-TYPE VEHICLES
(FR) UNITÉ MOTRICE POUR VÉHICULES À ENFOURCHER
(JA) 鞍乗り型車両のパワーユニット
Abstract
(EN)
This power unit for straddle-type vehicles is equipped with: a crankcase (38) that rotatably supports a crankshaft (61); a rotor (72) that is provided upon the crankshaft (61) on the outer side of the crankcase (38) and rotates about the axis of rotation (Rx) of the crankshaft (61); and an ACG cover (55) that is connected to the crankcase (38), surrounds the rotor (72) around the axis of rotation (Rx), and forms a housing space for the rotor (72). The ACG cover (55) is provided with an inner member (55a) that surrounds the rotor (72) around the axis of rotation (Rx), and an outer member (55b) that is connected to the inner member (55a) and covers the inner member (55a) further outward of the rotor (72) in terms of the axial direction. The present invention thereby provides a power unit for straddle-type vehicles that is capable of, by means of a rotary body cover, excellently protecting a rotary body provided to a crankshaft on the outer side of a crankcase.

L'invention concerne une unité motrice pour véhicules à enfourcher, laquelle unité comporte : un carter de vilebrequin (38) qui supporte en rotation un vilebrequin (61) ; un rotor (72) qui est disposé sur le vilebrequin (61) sur le côté externe du carter de vilebrequin (38) et qui tourne autour de l'axe de rotation (Rx) du vilebrequin (61) ; et un capot de générateur de courant alternatif (55) qui est relié au carter de vilebrequin (38), entoure le rotor (72) autour de l'axe de rotation (Rx), et forme un espace de logement pour le rotor (72). Le capot de générateur de courant alternatif (55) comporte un élément interne (55a) qui entoure le rotor (72) autour de l'axe de rotation (Rx), et un élément externe (55b) qui est relié à l'élément interne (55a) et qui recouvre l'élément interne (55a) davantage vers l'extérieur du rotor (72) en termes de direction axiale. La présente invention procure ainsi une unité motrice pour véhicules à enfourcher qui est apte, au moyen d'un capot de corps rotatif, à protéger de manière excellente un corps rotatif disposé sur un vilebrequin sur le côté externe d'un carter de vilebrequin.

鞍乗り型車両のパワーユニットは、回転自在にクランク軸(61)を支持するクランクケース(38)と、クランクケース(38)の外側でクランク軸(61)上に設けられ、クランク軸(61)の回転軸線(Rx)回りで回転するローター(72)と、クランクケース(38)に結合されて、回転軸線(Rx)回りでローター(72)を囲みローター(72)の収容空間を形成するACGカバー(55)とを備える。ACGカバー(55)は、回転軸線(Rx)回りでローター(72)を囲む内側部材(55a)と、内側部材(55a)に結合されて、軸方向にローター(72)よりも外側で内側部材(55a)を覆う外側部材(55b)とを有する。これにより、クランクケースの外側でクランク軸に設けられる回転体を回転体カバーで良好に保護することができる鞍乗り型車両のパワーユニットを提供する。
