A coupling assembly includes first and second coupling members, a locking member, and a blocking structure. The locking member may be a strut, a pawl, or the like. The locking member is disposed between the coupling members and is movable between a coupled position and a decoupled position. The coupling position is characterized by abutting engagement of the locking member with each coupling member. The decoupled position is characterized in that the locking member is in non-abutting engagement with at least the first coupling member. A blocking structure is associated with at least one of the first coupling member and the locking member. The blocking structure prevents the locking member from entering the coupled position when rotation of the first coupling member in the first direction relative to the second coupling member is above a predetermined rotational speed, thereby preventing abutting engagement of the locking member with the first coupling member.
一种耦合组件包括第一耦合构件和第二耦合构件、锁定构件和阻挡结构。锁定构件可以是支柱、棘爪等。锁定构件设置在耦合构件之间并且能在耦合位置与解耦位置之间移动。耦合位置的特征在于锁定构件与每个耦合构件抵接式接合。解耦位置的特征在于锁定构件至少与第一耦合构件非抵接式接合。阻挡结构与第一耦合构件和锁定构件中的至少一个关联。当第一耦合构件相对于第二耦合构件在第一方向上的旋转高于预定旋转速度时,阻挡结构阻止锁定构件进入耦合位置,从而阻止锁定构件与第一耦合构件抵接式接合。
