Title (EN) ELECTRICAL BICYCLE HUB
(FR) MOYEU DE BICYCLETTE ELECTRIQUE
Abstract:
(EN) Electrically motorised bicycle hub with a stationary wheel shaft which rotatingly supports a hub housing, in which is provided a rotor which can rotate around the wheel shaft and which comprises- a first part, parallel to the wheel shaft and carrying a ring of permanent magnets which cooperate with a ring of stator windings, supported by a carrier, and a second part rotatingly supported by the wheel shaft and connected to the first part by means of a transition part, and with furthermore a wheel transmission, driven by this second rotor part and which reduces the rotation speed thereof, the output thereof driving the hub housing, this wheel transmission being accommodated in the space between the stator windings and the wheel shaft. Preferably, the first rotor part is rotatingly supported on one of the hub walls opposite thereto while seals are provided between the cylindrical winding carrier and the parts opposite thereto.
(FR) Moyeu de bicyclette électriquement motorisée, comportant un arbre de roue stationnaire qui supporte en rotation un logement de moyeu, dans lequel est disposé un rotor qui peut tourner autour de l'arbre de roue et qui comprend - une première pièce, parallèle à l'arbre de roue et portant un anneau d'aimants permanents qui coopèrent avec un anneau de bobinages de stator, supportée par un porteur, et une seconde pièce supportée de manière rotative par l'arbre de roue et reliée à la première pièce au moyen d'une pièce de transition, ainsi qu’une transmission de roue, entraînée par cette seconde pièce de rotor et qui réduit la vitesse de rotation de celle-ci, la sortie de celle-ci entraînant le logement de moyeu, cette transmission de roue étant disposée dans l'espace entre les bobinages de stator et l'arbre de roue. Avantageusement, la première pièce de rotor est supportée de manière rotative par l'une des parois du moyeu qui lui est opposée, tandis que des joints d'étanchéité sont prévus entre le porteur d'enroulement cylindrique et les pièces qui lui sont opposées.
