Title (EN) WHEEL DRIVE DEVICE
(FR) DISPOSITIF D'ENTRAÎNEMENT DE ROUE
(JA) 車輪駆動装置
Abstract:
(EN) A shaft extends in the direction of the center axis. A hub has a side surface, an inner cylinder, and an outer cylinder, and is capable of rotating relative to the shaft. A stator is provided coaxially with the hub in a non-rotatable manner, is annularly disposed between the inner cylinder and the outer cylinder in a radial direction, and has a coil. A rotor is disposed coaxially with the stator utilizing the space between the stator and the side surface, holds a magnet subjected to a magnetic force from the coil, and is rotatable about the center axis. A ring gear is disposed coaxially with the inner cylinder and is affixed to the hub. A flexible gear is disposed facing the ring gear in the radial direction, is affixed to the stator, and partially meshes, between the inner cylinder and the stator, with the ring gear. A wave motion generator is disposed on the opposite side, radially, of the flexible gear from the ring gear.
(FR) Un arbre s'étend dans la direction de l'axe central. Un moyeu comporte une surface latérale, un cylindre interne et un cylindre externe, et peut tourner par rapport à l'arbre. Un stator disposé immobile en rotation de manière coaxiale au moyeu est positionné de manière annulaire entre le cylindre interne et le cylindre externe dans une direction radiale, et comporte une bobine. Un rotor est disposé de manière coaxiale au stator par le biais de l'espace séparant le stator et la surface latérale, maintient un aimant soumis à une force magnétique provenant de la bobine, et peut tourner autour de l'axe central. Une couronne dentée est disposée de manière coaxiale au cylindre interne et est fixée au moyeu. Un engrenage flexible est disposé en regard de la couronne dentée dans la direction radiale, est fixé au stator et engrène partiellement, entre le cylindre interne et le stator, avec la couronne dentée. Un générateur de mouvement d'onde est disposé radialement du côté opposé de l'engrenage flexible par rapport à la couronne dentée.
(JA) シャフトは、中心軸の軸方向に延びる。ハブは、側面部と内筒部と外筒部とを有し、シャフトに対して相対回転可能である。ステータ部は、ハブに対して同軸上に回転不可に設けられ、径方向において内筒部と外筒部との間に環状に配置され、コイルを有する。ロータ部は、ステータ部と同軸上に、ステータ部と側面部との間の空間を利用して配置され、コイルからの磁力を受けるマグネットを保持し、中心軸を中心に回転可能である。リング歯車は、内筒部に対して同軸上に配置され、ハブに固定される。可撓性歯車は、リング歯車と径方向に対向して配置され、ステータ部に固定され、内筒部とステータ部との間の位置でリング歯車と部分的に噛み合う。波動発生器は、径方向において、可撓性歯車を挟んでリング歯車とは反対側に配置される。
