Since the solid-star gear has more teeth than the planetary gear 11, the speed of the planetary gear of the gear is higher than that of the unidirectional driving device 7 and can reach a high-speed state. As shown in FIG. 2C, by using the claw 1 installed on the side of the sun gears 12, 13: f teeth Γ protrusion ^ and a control sleeve 21 to perform the change control unit. That is, 'use fixed to the control sleeve 21 As a result, the fixed gears have been fixed, or the stellar gears have been released from the f-claws i2a, 13a, thereby operating each shifting stage. As shown in the low-speed state shown in Figure 2A, the two claws are used to hold up 6a. Released from the control sleeve 21. In the first high-speed state of the wheel, the first star of the wheel is not fixed because of a claw 12 ", the strange star gear 12 fixed by the control sleeve. The gear is turned, so the larger direct service part of the gear U is connected with the #. On the other hand, when the other pawl 13a grasps the control sleeve 21, the other star gear rotates. Therefore, as shown in FIG. 2C, the lever "Tansi" ± core wheel 12 can be toothed at 13 and the smaller diameter part of the gear of the hall is engaged with the fixed star wheel 13. That is, this is the second high-speed state. To each other 丨 at the above-mentioned speed In the control type, since the two pawls 12a, 13a are installed in the phase, there are disadvantages.

This bracket (or ring gear 240) and the wheel seal are used. The rear 310 is rotated by the clutch ring. However, depending on the situation, ratchet knobs can replace the clutch ring and the inclined part 24ι. / As shown in FIGS. 5 and 6, the grooves are formed on the inner surface of the pawl control ring with respect to the center scale, and the positions of the pawls 421, 422 are controlled. The ten grooves include a pair of inclined grooves 431 and a pair of angled groove poles, and the inclined grooves and the angled grooves 432 are alternately formed on the inner surface of the pawl control ring 43. ~ Although the grooves are not formed at the same interval, the pawls 421 and 422 are installed at the pawl positioning portion 411 at the same interval, and selectively and smoothly control only one group of pawls. 〇 And, as shown in FIG. 7, the pawls 421 and 422 include depressions 421 a and 422 a which are located inside the pawl control frame 430; and the stoppers 421 b and 422 b formed along the inner periphery of the sun gear 231 and 232. The ratchet teeth 23h, 232 & engage or disengage. The pawl 々㈡ relatively far from the pawl control ring 43o further includes an extension 422c which is thinner than the pawl body to prevent the pawl 422 from engaging with other elements. In the following, for convenience, the pawl 421 is shown as the} th pawl, and it is close to the pawl control ring 430 (the intergrowth gear 231 (denoted as the i-th stellar gear), and the pawl is shown as the second pawl. Stellar gear 232 (indicated as the second stellar gear) is sprayed in. ^ The middle portion 440 includes-a spline groove 433 formed on the pawl control ring 43o side; _ a connecting portion 44ia that meshes with the flower and groove 433, and is formed in The inner connecting groove 441; and two collars 442 'installed in the connecting groove 441 are sprayed together with the spline portion 453 formed in the shifting willow to transmit the rotation force of the wheel. The red spacer 470 also includes a support section W, which supports-installs bearings between bracket 21 and support 4 471; a fixed disk 472 fixed to the wheel pumping; and a plurality of spacer pins 473 'which are fixed to the fixed disk 472, And through-an arc-shaped groove formed in the indexing disk 45, contacting the support portion 471. And the 'support portion 47 丨 can be rotated' A through hole 47la is formed in it so as not to hinder the rotation of the middle portion 440. FIG. 8 shows a cross-sectional view of another embodiment of the present invention, that is, the device includes three segments of row teeth Wheels 220, two strange star gears η, ^, such as, and-planetary gears 22, each of which are extended speed control units for controlling the speed state to the finer state. That is, 'including more than two groups In the above claw situation τ, the plural-view control ring is installed between each group of claws. However, except for the shape change, other components are the same as the previous embodiment. 10 As described above, the present invention can be further expanded. The reason for the f is that the control of the inter-speed transmission is mostly in the green part, and there are very few restrictions on increasing the speed knob. Therefore, more than four transmission sections are also possible. The operation and effect of the placement are as follows according to the present invention 'having the above structure. This is described by the bicycle shifter. ▲ The following describes the i-th embodiment of the present invention with reference to FIGS. 3 to 7 and FIGS. 9A to 9C, that is, the low-speed state, the medium-speed state, and the high-speed state. As shown in Fig. 9A, in the low-speed state, both the second and second pawls 42 and 2 are not in the groove 43 and 432 of the pawl control ring 430, that is, they are not connected with the second and second weirds. • 231 And 232 are combined. When the driven sprocket is rotated by stepping on the bicycle, the The driven key wheel _ ringing of the bracket 210 also rotates. Then the driving force of the 'bracket 210' is transmitted to the second shell 310 through the clutch farm 32 °. In this case, of course, it is sprayed with the permanent gears 231, 232. The planetary gear 22 and the carrier 210 rotate together. However, since the sun gears 231 and 232 are in a free state, the planetary gear 220 idles. 2. The medium-speed state is in the medium-speed state. The shift control unit is shown in FIG. 9B The configuration, that is, when the rider operates a lever (not shown), the 'displacement disc 45' is rotated to a certain degree by being connected to the lever with a connecting device such as a metal wire. The dry displacement disc 450 rotates When it reaches a certain level, the collar 442 connected to the spline part 々η of the index plate 45 is rotated, and the claw control ring 430 is also rotated. ° Therefore, the first pawl 421 is located in the inclined groove 431 and protrudes outward. As a result, the third pawl 421 meshes with the ratchet teeth 231a of the first sun gear 231. "J453 At this time, the second pawl 422 does not all protrude. This situation is better because it is sensitive to one action below the pawl control ring" ο. There are few rales. In the above-mentioned medium speed state, by stepping on the bicycle, when the driven sprocket 100 rotates, the bracket 210 engaged with the driven sprocket 100 also rotates. Then, the planetary gear 220 also rotates. However, in this case, since the tooth portion of one of the large diameter (first stage) of the planetary gear 220 meshes with the fixed first sun gear 231, the planetary gear 220 rotates. Faster than the bracket 21. Under the condition that the rotation speed of the bracket 210 is constant, the speed ratio of medium speed (calculated by the number of gear teeth) is as follows: ^ Speed fit 1st stage planetary gear X 1st sun gear _ ring gear segment planet gear ~ __1 + 1st star The gear ring gear's speed increase in this embodiment is about 1.5 times of the low speed state. As a result, when the planetary gear 220 rotates, the rotation speed of the ring gear 240 exceeds the speed of the carrier, and the clutch device 320 becomes a faster part that transmits the rotation to the hub shell 31o. 3. High-speed state In the above-mentioned medium-speed state, when the rider operates a lever, the index plate 45 is rotated at a high-speed state as shown in FIG. 9c. When the indexing disk 450 is rotated to a certain degree, the collar 442 connected to the spline part 453 of the indexing disk 45 rotates, and the pawl control ring 43 θ also rotates as if it is at a medium speed. Therefore, the first pawl 421 moves toward the inner position of the pawl positioning portion 々η of the hub shaft 41o, and the second pawl 422 is located at the angled groove 432 and protrudes outward. As a result, the second pawl 422 meshes with the ratchet teeth 232a of the second sun gear 232. In the above-mentioned high speed state, when the driven sprocket is rotated by stepping on the bicycle, the bracket 210 engaged with the driven sprocket 100 is also rotated. Then, the planetary gear 220 also rotates. However, in this case, since the tooth portion of the small diameter (second stage) of the planetary gear 22 is engaged with the fixed second sun gear 232 by the second pawl 422, it is like a medium speed. In this state, the planetary gear 220 rotates 12 1225453 faster than the carrier 210. Bottom: And, when the rotation speed of the bracket 不变 is unchanged, the speed ratio of high speed (calculated by the number of teeth of the wheel), such as speed ratio = 1 + poor

The detent pawl 321 is engaged with the% gear portion 322 by the operation of a spring 321a mounted on the planetary gear 220. Therefore, the rotational force of the driven sprocket 100 is transmitted to the hub shell 310 'by the engagement of the first pawl 321 and the ring gear, regardless of the state of the speed. Fig. 11 is a sectional view of the fourth embodiment. In this embodiment, the structure is the same as that of the third embodiment. Among them, the assembly direction of the planetary gear 220 is opposite to that of the third embodiment, and a first gripper 323 (installed in an air-closing device 320 generated by changing the direction of the planetary gear 22 °. ^ Zuo Ma Li 13 WZD453 a ring gear 242 is coupled with the planetary gear 220 and the second pawl 323 at the same time, and is installed outside the second-generation pawl 323, and a third pawl 324 is installed between the ring gear 242 and the hub shell 310. Other components and the third implementation The example is the same. "Therefore, at a low speed, the rotational force of the driven sprocket 100 is transmitted to the hub shell 310 via the third pawl 324 and the engagement of the second pawl 323 with the ring gear 242. And at a medium speed In the state and the speed direction, the rotational force of the driven sprocket 100 is transmitted to the wheel chaff through the ring gear 42 and the second pawl 324 ′ by the coupling of the planetary gear 22 °. 1 In the dog state and the high speed state, the second pawl 323 also rotates with the ring gear 242, which is a fast Kossam, because the rotation of the planetary gear 22G is more industrially available than the driven sprocket 100. The invention of the mysterious wheel and the mysterious thread of the foot is installed inside: the internal gear changes the foot The speed of the treadmill is easy to control, and the control effect is immediate: the treadmill has a good appearance, and the gear shifts. The speed of the bike is very low, and the shifting section is easy to expand.
