The invention discloses a silent hub which comprises main components such as a gear cylinder, a fixed ratchet disc, a free fluted disc, a propelling disc, a rotary linkage component, a guide base, an axial propelling component, a reset torsion spring and a magnetic attraction component. When the free fluted disc is located at the release position, the gear cylinder is in a fixed non-rotating mode, and at the moment, the free fluted disc can be reset to the release position due to the fact that the axial pushing component does not conduct axial abutting and pushing actions and the magnetic attraction force of the magnetic attraction component. Therefore, the state that the driving convex part and the driven convex part of the rotary linkage component are meshed with each other and the free fluted disc and the fixed ratchet disc are completely separated from each other is formed. According to the silent hub, when pedals are not treaded in the advancing process of the bicycle, sound and resistance caused by mutual clamping of the ratchets are avoided, and the ideal silent and zero-resistance state can be really achieved.

    本发明公开了一种无声花毂,包括齿轮筒、固定棘齿盘、游离齿盘、推进盘、旋转连动构件、导动座、轴向推动构件、复位扭簧及磁吸构件等主要构件;其中游离齿盘处于释放位置时,齿轮筒呈定止未转动模式,此时因轴向推动构件尚未进行轴向抵推动作,加上磁吸构件的磁吸力会使游离齿盘往释放位置复位,故构成旋转连动构件的带动凸部与受动凸部之间相咬合以及游离齿盘与固定棘齿盘之间完全脱开的状态;本无声花毂在自行车行进过程中踏板未踩踏状态下,不会有棘齿相互卡动的声音及阻力存在,确实能够达到无声及零阻力的理想状态。
