摘要： A retaining device includes a pair of annular retaining members and a pair of securing members. Each annular retaining member is adapted to be interposed between an axle and enlarged head portions of spoke tightening members in an annular space defined between the axle and an annular inner peripheral wall of a tubular mount member. The annular retaining member includes an annular inner ring portion sleeved on the axle, an annular outer ring portion surrounding and rotatable relative to the annular inner ring portion, and a rolling element disposed between the annular inner and outer ring portions. Each securing member is disposed to secure the annular inner ring portion on the axle such that the annular outer ring portion faces towards the enlarged head portions so as to guard shoulders of the spoke tightening members against being loosened from abutment with the inner peripheral wall.

摘要翻译： 保持装置包括一对环形保持构件和一对固定构件。 每个环形保持构件适于被插入在轴和与辐条紧固构件的扩大头部之间的环形空间中，所述环形空间限定在所述轴与管状安装构件的环形内周壁之间。 环形保持构件包括套在轴上的环形内环部分，围绕环形内圈部分环绕并可旋转的环形外环部分，以及设置在环形内环部分和外环部分之间的滚动元件。 每个固定构件设置成将环形内环部分固定在轴上，使得环形外环部分朝向扩大的头部部分，以便防止辐条紧固构件的肩部松动而与内周壁抵接。

摘要： A bicycle hub is provided with spoke openings that extend into the interior of the hub. The bicycle hub basically has a hub axle, a hub body and seals arranged in the hub body. The hub axle has a center axis extending between a first end and a second end. The hub body has an interior passageway with the hub axle being rotatably supported therein. The hub body also has first and second spoke openings circumferentially arranged around the ends of the hub body. A first seal is arranged in the interior passageway of the hub body and adjacent the first spoke openings to isolate the first spoke openings from the hub axle. A seal support is located beneath the first seal to prevent radial inward movement of the first seal. A second seal is arranged in the interior passageway of the hub body and adjacent the second spoke openings to isolate the second spoke openings from the hub axle. Preferably, the spoke opening covers are located in grooves of the hub body to seal the insertion portions of the first and second spoke openings.

摘要翻译： 自行车轮毂设置有延伸到轮毂内部的轮辐孔。 自行车轮毂基本上具有轮毂轴，轮毂体和布置在轮毂体中的密封件。 轮毂轴具有在第一端和第二端之间延伸的中心轴线。 轮毂体具有内部通道，轮毂轴可旋转地支撑在其中。 轮毂体还具有绕毂体的端部周向布置的第一和第二轮辐孔。 第一密封件布置在毂体的内部通道中并且邻近第一轮辐孔以将第一轮辐孔与轮毂轴隔离。 密封支撑件位于第一密封件下方，以防止第一密封件向内径向向内移动。 第二密封件布置在毂体的内部通道中并且邻近第二轮辐孔以将第二轮辐孔与轮毂轴隔离。 优选地，轮辐孔盖位于轮毂体的凹槽中，以密封第一和第二轮辐孔的插入部分。

摘要： A bicycle rim includes side portions with an outer portion extending between the side portions to form a pair of outer corners, and a spoke attachment portion. The outer portion includes a pair of ridges spaced from the outer corners. The ridges preferably divide a pair of inclined surfaces. The side portions preferably include a pair of ground braking surfaces with a pair of sloping surfaces extending from the braking surfaces to a pair of outer side surfaces.

摘要翻译： 自行车轮辋包括第一和第二环形侧部，其内侧环形部分在侧部之间延伸，而外环形轮胎安装部分在侧部之间延伸。 外环形轮胎安装部具有围绕轮辋的中心轴线布置的非圆形外周边缘。 内环形部分和第一和第二环形侧部分中的至少一个包括多个周向间隔开的轮辐孔。 非圆形的外周边缘具有从边缘的中心轴线延伸并且穿过轮辐孔的第一半径，其大于在选定的周向相邻的轮辐孔对之间通过中途的非圆形外周边缘的第二半径。
