A bicycle transmission assembly may include an axle, a hub housing rotatably mounted on the axle via a first bearing, a free hub rotatably mounted on the axle via a second bearing, and a ratchet mechanism releasably coupling the free hub to the hub housing to transfer torque from the free hub to the hub. The ratchet mechanism may include a first ratchet ring having an inner surface coupled to the hub housing for rotation therewith and a second ratchet ring having an inner surface coupled to the free hub for rotation therewith. The first and second ratchet rings surround and radially overlap the first and second bearings, respectively. At least one spring resiliently biases the first and second ratchet surfaces into engagement to transfer torque from the free hub to the hub housing.

    一种自行车传动组件可包括轮轴、通过第一轴承可旋转地安装在轮轴上的毂壳体、通过第二轴承可旋转地安装在轮轴上的自由毂以及棘轮机构,所述棘轮机构将自由毂可释放地耦接到毂壳体以将转矩从自由毂传递到毂。棘轮机构可包括第一棘轮环和第二棘轮环,第一棘轮环具有联接到毂壳体用于随毂壳体一起旋转的内表面,并且第二棘轮环具有联接到自由毂用于随自由毂一起旋转的内表面。第一棘轮环和第二棘轮环分别围绕并径向叠覆第一轴承和第二轴承。至少一个弹簧弹性地偏压第一棘轮面和第二棘轮面进入接合以将转矩从自由毂传递到毂壳体。
