摘要 一種自行車輪轂總成包含輪轂軸、輪轂殼、鏈輪支撐本體、及離合器。鏈輪支撐本體被可旋轉地安裝在輪轂軸上以繞旋轉軸線旋轉。鏈輪支撐本體可繞旋轉軸線相對於輪轂軸及輪轂殼旋轉。離合器具有踩踏旋轉力在踩踏期間從鏈輪支撐本體於第一旋轉方向被傳輸至輪轂殼的第一耦接狀態、輪轂殼在滑行期間可相對於鏈輪支撐本體於第一旋轉方向旋轉的第一釋放狀態、及滑行旋轉力在滑行期間從輪轂殼於第一旋轉方向被傳輸至鏈輪支撐本體的第二耦接狀態。 A bicycle hub assembly comprises a hub axle, a hub shell, a sprocket support body, and a clutch. The sprocket support body is rotatably mounted on the hub axle to rotate about a rotational axis. The sprocket support body is rotatable relative to the hub axle and the hub shell about the rotational axis. The clutch has a first coupling state where a pedaling rotational force is transmitted from the sprocket support body to the hub shell in a first rotational direction during pedaling, a first release state where the hub shell is rotatable relative to the sprocket support body in the first rotational direction during coasting, and a second coupling state where a coasting rotational force is transmitted from the hub shell to the sprocket support body in the first rotational direction during coasting.
