    • An expansion engagement crank assembly for a bicycle. The assembly includes a female crank arm, a male crank arm, and a connector for connecting the female arm and the male arm. The female arm has a shaft sleeve attached at one end, the sleeve having an inboard end, an outboard end, and a bore originating at the inboard end. The bore is bounded by a mating surface and a a fastener surface. The male arm has a shaft attached at one end and the shaft has a radially expandable inboard end and an outboard end. The inboard end of the shaft is sized for insertion within the bore of the sleeve and has a complimentary mating exterior surface for engaging the mating surface bounding the bore. The shaft additionally has an interior coupling surface defining a passage extending through the shaft from the inboard end to the outboard end. The connector is sized for placement within the bore of the sleeve and the passage of the shaft. The connectors also shaped for engaging the fastener surface bounding the bore and for engaging the coupling surface defining the passage to connect the male arm with the female arm. The connector is additionally shaped to radially expand the mating surface of the shaft into an engaged position with the mating surface of the sleeve when the connector connects the male arm and female arm.
    • 一种用于自行车的膨胀接合曲柄组件。 该组件包括一个雌性曲柄臂,一个雄性曲柄臂,以及一个用于连接雌性臂和雄性臂的连接器。 母臂具有一端连接的轴套,套筒具有内侧端部,外侧端部以及起始于内侧端部的孔。 孔由配合表面和紧固件表面限定。阳臂具有在一端附接的轴,并且轴具有可径向扩张的内侧端部和外侧端部。 轴的内侧端部的尺寸适于插入套筒的孔内,并且具有互补的配合外表面,用于接合围绕孔的配合表面。 该轴还具有内部联接表面,该内部联接表面限定了从内侧端部延伸穿过轴的通道到外侧端部。连接器的尺寸适于放置在套筒的孔内和轴的通道中。 所述连接器还成形为用于接合限定所述孔的紧固件表面,并且用于接合限定所述通道的联接表面以将所述阳臂与所述阴臂连接。 连接器另外成形为当连接器连接阳臂和阴臂时,将轴的配合表面径向地扩展成与套管的配合表面接合的位置。

    • A bottom bracket assembly for a bicycle is provided. The bottom bracket assembly may comprise a left bearing, bottom bracket shell and a right bearing. The bottom bracket shell may be threadless and have beveled surfaces for mounting the left and right bearings onto the bottom bracket assembly. A spindle is inserted through the bottom bracket shell. Thereafter, the left and right bearings are preloaded to align the central axis of the spindle to the crankarm rotating axis such that the spindle or left and right crankarms do not wobble and yet do not bind when rotated.
    • 提供了一种用于自行车的底部支架组件。 底部托架组件可以包括左轴承,底托架壳体和右轴承。 底托架外壳可以是无螺纹的,并具有用于将左右轴承安装到底托架组件上的斜面。 主轴通过底托架壳体插入。 此后,左轴承和右轴承被预加载以使主轴的中心轴线与曲柄臂旋转轴线对齐,使得主轴或左右曲轴臂在旋转时不会摆动并且不会结合。
