摘要： A bicycle unit hub incorporates a hub shell rotatably supported on a hub shaft, a core mounted to one end of the hub shell for co-rotation therewith, a sprocket carrier supported around the core to rotate relative thereto only in one direction, and a hollow bolt inserted into the hub shell from the other end thereof. The bolt has a head engageable with an annular step formed on the hub shell. The bolt also has a threaded tip portion for engagement with an internally threaded portion of the core or a nut, so that the hub shell is clamped between the bolt head and the core with resultant fixation of the core.

摘要： A quick-release type clamping assembly for a bicycle hub comprises a tie rod having a threaded portion at one end and formed at the other end with an enlarged head. An end nut is screwed on the threaded portion of the tie rod. A presser member is fitted around the enlarged head, the presser member being movable relative to the enlarged head axially of the tie rod toward and away from the end nut in response to pivotal movement of an operating lever. A hub stopper is provided to surround at least one of the end nut and the presser member. The stopper is movable axially of the tie rod between an advanced position and a retreated position, and has a engaging portion for engagement with a corresponding fork end to prevent the hub from displacing relative to the fork end when the stopper assumes the advanced position. A locking mechanism holds the hub stopper in the advanced position.
摘要翻译：用于自行车轮毂的快速释放型夹紧组件包括一杆，其一端具有螺纹部分，并在另一端形成一个扩大的头部。一个端螺母拧在拉杆的螺纹部分上。压脚构件安装在扩大的头部周围，压脚构件可响应于操作杆的枢转运动而相对于拉杆的轴向相对于端螺母相对于扩大的头部移动。轮毂止动件设置成围绕端部螺母和压紧构件中的至少一个。止动件可以在拉杆的轴向移动到前进位置和后退位置之间，并且具有接合部分，用于与相应的叉形端部接合，以防止当止动器处于前进位置时轮毂相对于叉形端部移位。锁定机构将轮毂止动器保持在前进位置。

摘要： A theftproof quick-release type clamping assembly for mounting a bicycle part comprises a tie rod having one end screwed to an end nut and formed at the other end with an enlarged head, and a hollow presser member fitted around the enlarged head as movable relative thereto axially of the tie rod toward and away from the end nut in response to pivotal movement of a lever which has a shaft portion penetrating the presser member and the enlarged head. A lock member screwed to the enlarged head is advanced into abutment with the presser member when the presser member is axially moved toward the end nut, thereby directly limiting axial movement of the presser member away from the end nut. In this condition, the lever can be manually removed from the presser member and the enlarged head without using any tool, thus providing theft prevention.
摘要翻译：一种用于安装自行车部件的防盗快速释放型夹紧组件包括一根拉杆，该拉杆的一端螺纹连接到一个端部螺母上，并在另一端形成一个扩大的头部，一个中空压紧件安装在扩大头部周围，可相对于其移动响应于具有穿过压紧构件和扩大头部的轴部分的杆的枢转运动，拉杆的轴向方向朝向和远离端部螺母。当压紧构件朝向端部螺母轴向移动时，螺纹连接到扩大头部的锁定构件被推进成与压紧构件邻接，从而直接限制压紧构件远离端部螺母的轴向运动。在这种情况下，可以在不使用任何工具的情况下从压脚构件和扩大的头部手动地移除杠杆，从而提供防盗。

摘要： A removal preventing mechanism for preventing unexpected removal of a bicycle hub assembly comprises a latch member pivotally mounted to each fork end having a hub mounting cutout which receives a hub shaft. The latch member is pivotable between a locking position for preventing removal movement of the hub shaft from the hub mounting cutout of the fork end and an unlocking position for allowing movement of the hub shaft from and into the hub mounting cutout. The latch member is normally urged to the locking position by a spring.
摘要翻译：用于防止意外移除自行车轮毂组件的防止移除机构包括枢转地安装到每个叉端的闩锁构件，其具有容纳轮毂轴的轮毂安装切口。闩锁构件可以在用于防止轮毂轴从叉形端部的轮毂安装切口的移除移动的锁定位置和用于允许轮毂轴从轮毂安装切口移动到该轮毂安装切口之间的解锁位置之间枢转。闩锁构件通常由弹簧推动到锁定位置。
