摘要： A freewheel of a vehicle, in particular a two-wheeler, includes (i) a crankshaft, (ii) an output shaft having a first gear cog, (iii) a freewheel element having a second gear cog, and (iv) a friction element. The first gear cog and the second gear cog are configured to, when engaged with each other, effect a torque transfer between the output shaft and the freewheel element. The freewheel element is arranged to be displaceable in an axial direction on the crankshaft. The freewheel element is arranged to be non-rotatable relative to the crankshaft in the circumferential direction. The freewheel element and the friction element are connected to one another by means of a helical mechanism, which is configured to effect a translational displacement of the freewheel element and the friction element relative to one another when the freewheel element and friction element rotate relative to one another.

摘要： A pedaled drivetrain includes a drive mechanism, a wheel, a freewheel hub, and a locking mechanism. The wheel has a rotational axis. The freewheel hub connects the drive mechanism to the wheel, and the freewheel hub transmits torque from the drive mechanism to the wheel in a first rotational direction around the rotational axis. The locking mechanism has a locked state and an unlocked state. The locked state rotationally fixes a component of the drive mechanism to the wheel relative to the rotational axis.

摘要： In a drive unit attached to a vehicle-body frame of an electric-motor-assisted bicycle including a one-way clutch including an outer member, an inner member, a plurality of clutch lugs, a plurality of springs, and a plurality of pins. Clutch teeth are located on one of an inner peripheral portion of the outer member and an outer peripheral portion of the inner member. The clutch lugs and the springs are located on the other of the inner peripheral portion and the outer peripheral portion. A number of the clutch lugs is an even number not smaller than four. A number of the clutch teeth is an even number that is not a multiple of the number of the clutch lugs. A number of the springs is half the number of clutch lugs. Each spring exerts a biasing force on two of the clutch lugs that are circumferentially adjacent. Each pin is in contact with one of the springs.

摘要： A bicycle drive unit is basically provided with an input rotational shaft, an output part, a transmission mechanism, an assist motor and a switching mechanism. The transmission mechanism has at least two shift stages, and is configured to change a speed of a rotational input that is input from the input rotational shaft and output this rotational input to the output part. The assist motor is coupled to a power transmission path from the input rotational shaft to the output part, and is driven according to a manual drive force. The switching mechanism is configured to switch a gear changing state of the transmission mechanism by using a rotational force of the assist motor.

摘要： A center motor power-assisted bicycle includes an internal transmission and has a regenerative function. A transmission comprises, in a drive wheel hub, a planetary gear, a one-way clutch for reverse input, a clutch switching device, and, a sun gear and transmits driving force from a sprocket to the drive wheel. A transmission control mechanism selectively rotationally fixes the sun gear to the axle to change speed when driving force is applied. The clutch is disposed between the sun gear and the axle, and selectively rotationally fixes the sun gear to the axle by the operation of the clutch switching device when reverse input is applied. While the bicycle is driven, the clutch switching device moves the clutch to the rotatable state, to transmit driving force. While the bicycle is traveling without being driven, the clutch is locked, so that reverse input is transmitted to the sprocket.
