技術說明

本發明提供一種變速裝置，包含輪轂、調速單元、環齒輪、傳動組及磁控單元。輪轂有容置空間，調速單元設置於容置空間，調速單元包含桿體及磁力部，磁力部設置於桿體外表面。環齒輪設置於容置空間，環齒輪包含第一離合器並透過第一離合器與輪轂齧合或分離，環齒輪齧合帶動輪轂轉動。傳動組包含至少三傳動件及第二離合器，一傳動件與環齒輪齧合，另一傳動件透過第二離合器與輪轂齧合或分離且帶動輪轂轉動。磁控單元套設於桿體並受磁力部的吸引或排斥而作動，使磁控單元與又一傳動件齧合或分離以改變輪轂的轉動速度。 This invention provides a multi-speed hub which includes a hub shell, a controlling module, a ring gear, a gear module and a magnet module. The hub shell includes a receiving space. The controlling module includes a shaft and a magnetic portion. The magnetic portion is disposed at an outside surface of the shaft. The ring gear is disposed in the receiving space and includes a first clutch for engaging with or separating from the hub shell. The hub shell can be driven to rotate while engaged with the ring gear. The gear module includes at least three gears and a second clutch. One of the gears is engaged with the ring gear and another is engaged with or separated from the hub shell via the second clutch. The shell hub is driven to rotate while engaged with the other gear. The magnet module disposed at the shaft is engaged with or separated from further another gear via the attracting force or the repelling force of the magnetic portion to change the rotating speed of the hub shell.
