The above objects and advantages of the present invention will be readily understood from the following detailed description of the embodiments and the accompanying drawings. The following examples are used in conjunction with the drawings to illustrate the creation in detail:

Referring to Figures 1, 2A, 2B, 3 and 4A, the present invention is a one-way transmission having a central cutout, which includes an inner ring portion 10, an outer ring portion 20 and a central pumping unit. Change part 30. The inner ring portion 10 has a first inner annular surface 11 and a first outer annular surface 12, and the first inner annular surface 11 is used to connect an active structure A for the active structure A to the inner ring.

The double wide side structure 33B is provided at an outer surface position of the inner ring portion 10 and the outer ring portion 20. The inner ring portion 10 corresponds to the double wide side structure 33B and has an inner ring outer restricting groove 13A; the outer ring portion 20 corresponds to the double wide side structure 33B and has an outer ring outer restricting groove 23A.

[c] Third application example: Referring to Fig. 5A, one of the pair of restriction ring sheets is a single inner wide side structure 33C, and the other one is a single outer wide side structure 33D. The single inner wide side structure 33C is disposed at an outer surface position of the inner ring portion 10; the inner ring portion 10 corresponds to the inner inner wide side structure 33C, and has the inner ring outer restricting groove 13A. The single outer wide side structure 33D is disposed at an inner surface position of the outer ring portion 20; the outer ring portion 20 corresponds to a single outer wide side structure 33D and has an outer ring inner surface restricting groove 23B. The inner ring outer limiting groove 13A and the outer ring inner surface limiting groove 23B are respectively provided for the single inner wide side structure 33C and the single outer wide side structure 33D for assisting positioning of the central drawing portion 30. [d] Fourth Application Example: Referring to Fig. 5B, one of the pair of restriction ring sheets is a single outer wide side structure 33D, and the other one is a single inner wide side structure 33C. The single outer wide side structure 33D is disposed at an outer surface position of the outer ring portion 20; the outer ring portion 20 corresponds to the outer outer wide side structure 33D, and has the outer outer ring outer restricting groove 23A. The single inner wide side structure 33C is disposed at an inner surface position of the inner ring portion 10; the inner ring portion 10 corresponds to the single inner wide side structure 33C, and has an inner ring inner surface restricting groove 13B. The outer ring outer limiting groove 23A and the inner ring inner surface limiting groove 13B are respectively provided for the single outer wide side structure 33D and the single inner wide side structure 33C for assisting positioning of the central drawing portion 30. The active structure A can be at least one of a bicycle shifting device and a bicycle ratchet device. The passive structure B can be a rear wheel hub of the bicycle. This creation is mainly applied to the rear wheel hub of the bicycle, and has the following two modes of operation: [a] Linking the rear wheel: When stepping on the pedal, it is driven by the chain and the active structure A (this part is a practical industrial change) The figure is not disclosed, and the inner ring portion 10 is rotated (as shown in Fig. 6A). At this time, the one-way transmission path is as follows: the linkage plane 121 pushes the brake structure 322 → the brake structure 322 moves from the release position P2 to the transmission position P1 → the brake structure 322 and the first outer ring surface 12 (it can also be said The interlocking plane 121) and the second inner ring surface 21 are in contact with each other (see FIG. 6B). The outer ring portion 20 interlocks the structure B to output power. [b] When the pedal is not connected, the rear wheel: when the pedal is reversed, and driven by the chain and the active structure A (this part is an actual industrial change example, the picture is not disclosed, the first Chen Ming) the inner ring part 10 Rotate (as shown in Figure 7A). At this time, the structural linkage path is as follows: the linkage plane 121 pushes the brake structure 322 → the brake structure 322 moves from the transmission position P1 to the release position P2 (simultaneous compression of the elastic structure 321) → the brake structure 322 and the first At least one of the outer annular surface 12 and the second inner annular surface 21 is separated (as shown in FIG. 7B, a distance D is generated) → the inner ring portion 10 is not unidirectionally driven by the outer ring portion 20 → the outer ring The portion 20 is not linked to the structure B to output power. [c] Not stepping on during travel (idle): Refer to Figures 8A and 8B. For example, when the rear wheel rotates on the road surface when going downhill, the structural interlocking path is as follows: the second inner ring surface 21 pushes the brake structure 322 in the reverse direction. → the brake structure 322 is moved from the transmission position P1 to the release position P2 (simultaneous compression of the elastic structure 321) → at least one of the brake structure 322 and the first outer annulus 12 and the second inner annulus 21 Separated (generating this distance D). The brake structure 322 is held at the release position P2 and thus moves in reverse. The point is that the industry knows that if the bicycle hub (that is, the passive structure 90) is damaged and replaced, the price is high, especially if the transmission device and the ratchet device (ie, the active structure A) are added, the price is even higher. It is surprising that the central exchange portion 30 is provided in the present invention, and when at least one of the inner ring portion 10, the outer ring portion 20, the central cutout portion 30, the active structure A, and the passive structure B is damaged, The central cutout portion 30 can be pulled away from the first outer annular surface 12 and the second inner annular surface 21 to achieve a separable maintenance without replacing the assembly. The advantages and functions of this creation are as follows: [1] The removable structure reduces maintenance costs. This creation is provided with a central exchange part between the wheel hub, the shifting device and the ratchet device after the bicycle. Once any of the above devices is damaged and needs to be repaired and replaced, it is not necessary to replace the entire high assembly. For example, when a roller is damaged, it is only necessary to take out the central exchange and replace it, saving time and trouble. That is to say, the case only needs to replace the damaged components, which can reduce the high cost and time of replacing the entire assembly. Therefore, the removable structure reduces maintenance costs. [2] The central exchange department improves the repair and replacement speed. This creation sets the central exchange part. When the maintenance and replacement is required, the central exchange part is taken out, replaced, and then replaced, without the need for cumbersome screw locks (including taking screws, aligning screws with holes, and screw locks). . Therefore, the central exchange department improves the repair and replacement speed. The above is only a detailed description of the present invention by way of a preferred embodiment, and any modifications and variations of the embodiments are possible without departing from the spirit and scope of the present invention.
