摘要： A bicycle wheel basically has a central hub assembly, a plurality of spokes extending outwardly from the central hub assembly and an annular rim coupled to the outer ends of the spokes for supporting a tire. The central hub assembly has a hub axle, a hub unit, a freewheel and a sprocket assembly with a plurality of sprockets. The hub axle has a center axis extending between a first frame mounting end and a second frame mounting end. The hub unit has a hub body, a first spoke mounting portion, a second spoke mounting portion and an interior passageway. The first spoke mounting portion is located adjacent a first end of the hub body. The second spoke mounting portion is located adjacent a second end of the hub body. The interior passageway extends through the hub body with the hub axle being rotatably supported therein. The freewheel is operatively coupled between the first end of the hub axle and the first end of the hub body. The sprockets are coupled to the freewheel and axially spaced apart along the freewheel. The first spoke mounting portion has a recess that receives inner portions of the freewheel and the sprocket assembly therein. The first spoke mounting portion is also at least partially located in a radial center portion of one of the sprockets.

摘要翻译： 自行车车轮基本上具有中央轮毂组件，从中心轮毂组件向外延伸的多个轮辐，以及联接到轮辐的外端的环形轮缘，用于支撑轮胎。 中心轮毂组件具有轮毂轴，轮毂单元，自由轮和具有多个链轮的链轮组件。 轮毂轴具有在第一框架安装端和第二框架安装端之间延伸的中心轴线。 轮毂单元具有轮毂体，第一轮辐安装部分，第二轮辐安装部分和内部通道。 第一轮辐安装部分位于轮毂本体的第一端附近。 第二轮辐安装部分邻近轮毂体的第二端定位。 内部通道延伸穿过轮毂体，轮毂轴可旋转地支撑在其中。 自由轮可操作地联接在轮毂轴的第一端和轮毂本体的第一端之间。 链轮联接到自由轮并沿着自由轮轴向隔开。 第一轮辐安装部分具有容纳自由轮和链轮组件的内部的凹部。 第一轮辐安装部分还至少部分地位于一个链轮的径向中心部分中。

摘要： A ratchet mechanism for a bicycle hub includes a first hub member and a second hub member, wherein the first hub member and the second hub member are rotatable relative to each other. A pawl is supported by the first hub member, a ratchet tooth is supported by the second hub member, and a biasing mechanism is provided for biasing the pawl toward the ratchet tooth. A pawl control mechanism is responsive to relative rotation of the first hub member and the second hub member for allowing the pawl to contact the ratchet tooth when the first hub member and the second hub member rotate relative to each other in one direction and for preventing the pawl from contacting the ratchet tooth when the first hub member and the second hub member rotate relative to each other in an opposite direction.
