摘要： An overrunning clutch comprising a ratchet wheel (1) and a plurality of pawls (2) is disclosed. Each of the pawls (2) is rotationally supported on a disk member (5) by a shaft (3). The clutch is characterized by a permanent magnet (4) being fixed on the disk member (5) between the axes of the disk member (5) and the shaft (3) and facing the tail end of each pawl (2). Because each of the pawls are not driven by a spring in the clutch, the clutch could not be malfunction due to the fatigue failure of the spring in the case of frequent heavy load.

摘要： A power-assisted bicycle is provided with a one-way clutch that can also be used as a torque detection apparatus. The one-way clutch has a tooth part (112) mounted on a driven means and a piece part (100) mounted slidably yet non-rotatably on a drive shaft (4). The tooth part has a first engagement face (121) formed with a plurality of teeth (114) and the piece part has a second engagement face (110) formed with a plurality of pieces (102). The first engagement face and the second engagement face are disposed facing each other generally perpendicularly to the axial direction. A disc spring (124) is disposed on the rear face of the piece part. As the piece part rotates in the direction of running forward, the piece is engaged with a sharply sloping face of the tooth to engage with the tooth and the angle of the piece with respect to the second engagement face increases, whereby the piece slides so as to increase the distance from the tooth part in resistance to the disc spring. As the piece rotates in the opposite direction, the piece abuts with the gently sloping face of the tooth and the angle of the piece with respect to the second engagement face is made smaller to decrease the distance from the tooth part by means of the elasticity of the disc spring.

摘要： An apparatus for changing power direction for a bicycle is provided. The apparatus for changing power direction roughly including a shaft housing, a change ring, a carrier, a sun gear and a sprocket cap is located between a pedal shaft and a driving sprocket. The shaft housing supports the rotating pedal shaft and controls the carrier by using a plurality of pawls to be released from and inserted into a plurality of openings formed at the inside of a rim of a right cap of the shaft housing when pedaling rearward. The change ring releases and inserts the pawls from and into the shaft housing when pedaling rearward, and the carrier having a first ratchet and a second ratchet at the outside and inside of a left portion thereof, respectively, and a plurality of planetary gears to be rotatably set at a right portion maintains or changes the direction of power from the pedal shaft, thereby transmitting the power to a driving sprocket. The sun gear transmits the driving force of the pedal shaft to the carrier while being coupled with the pedal shaft. Also, the sprocket cap having a gear at the right of the inside of the rim thereof receives the power from the carrier to travel the bicycle forward at all times regardless of forward and backward pedaling directions. Therefore, the bicycle travels forward when pedaling forward and rearward in the state where the apparatus for changing power direction is installed to the bicycle. Also, an idling may occur if required when pedaling rearward in the state where the apparatus for changing power direction is installed to the bicycle.
摘要翻译： 提供一种用于改变自行车的动力方向的装置。 用于改变动力方向的装置位于踏板轴和驱动链轮之间，大体上包括轴壳，换环，载架，太阳齿轮和链轮盖。 轴壳体支撑旋转踏板轴并且通过使用多个棘爪来释放并插入到形成在轴壳体的右帽盖的边缘的内侧的多个开口中并且向后蹬时控制托架。 换挡环向后蹬踏时将棘爪释放并插入到轴壳体中，并且载体在其左部分的外侧和内侧分别具有第一棘轮和第二棘轮，并且多个行星齿轮为 可旋转地设置在右侧部分保持或改变来自踏板轴的动力方向，从而将动力传递到驱动链轮。 太阳齿轮将踏板轴的驱动力传递到载体，同时与踏板轴联动。 此外，具有在其边缘的内侧右侧的齿轮的链轮盖从承载件接收动力，一直向前行驶自行车，而不管前后踏板方向如何。 因此，在向自行车安装改变动力方向的装置的状态下向前和向后蹬踏时，自行车前进。 此外，如果需要，当在用于改变动力方向的装置安装到自行车的状态下向后蹬时可能发生怠速。

摘要： A doubly convertible bicycle wheel hub assembly has an axle housing containing sealed dustproof precision bearings with the axle journalled therein, the ends of the axle housing having annular retainers thereon either one of which can be replaced by a specialized retainer-freewheel mount element which, when the freewheel mechanism is mounted thereto, converts the hub assembly for use on the rear wheel of a bicycle. The freewheel assembly itself utilizes an annular sprocket element for the bicycle chain drive which is very simply removable and replaceable by removing a threaded retainer ring such that the chain drive ratio can be altered without replacing the entire freewheel mechanism.
