自行车驱动单元
摘要：
一种自行车驱动单元，所述自行车驱动单元包括：马达、曲柄轴和扭矩组合机构。曲柄轴绕着第一旋转轴线可旋转。扭矩组合机构操作地联接到马达和曲柄轴。扭矩组合机构具有链轮安装部分，该链轮安装部分构造为操作地附设到链轮，以使得随着曲柄轴在第一方向上绕着第一旋转轴线旋转，链轮在第一方向上绕着链轮的第二旋转轴线旋转。离合器机构操作地设置在曲柄轴与链轮之间。离合器机构构造为随着曲柄轴在第二方向上绕着第一旋转轴线旋转，使链轮在第二方向上绕着第二旋转轴线旋转。第二方向反向于第一方向。
摘要（英）：

A bicycle drive unit includes a motor, a crank axle, and a torque combining mechanism. The crank axle is rotatable about a first rotational axis. The torque combining mechanism is operatively coupled to the motor and the crank axle. The torque combining mechanism has a sprocket mounting portion that is configured to be operatively attached to a sprocket such that the sprocket rotates about a second rotational axis of the sprocket in a first direction as the crank axle rotates about the first rotational axis in the first direction. A clutch mechanism is operatively disposed between the crank axle and the sprocket. The clutch mechanism is configured to rotate the sprocket about the second rotational axis in a second direction as the crank axle rotates about the first rotational axis in the second direction. The second direction is opposite to the first direction.
