In order to make the tension of the left and right spokes of the rim consistent, the replacement of the sleeve i requires the tension of the web of the rim, so that the left and right tensions are the same, which is very time consuming and troublesome. As shown in the U! Figure, the sleeve is sleeved on the rear of the bicycle - the transverse center 2' of the other side of the core 2 - the rear hub 3, and the rear hub 3 and the sleeve 2 One of the inner ratchet rings 4 is assembled, and the outer side of the sleeve is re-locked with a screw sleeve 5, and the power is transmitted to the rear hub 3 by the sleeve i of different rhyme specifications, and the rear drum 3 then drives the rear wheel of the bicycle to rotate synchronously. Since the ratchet ring 4 of the sleeve i has different shifting specifications (usually eight-speed, nine-speed and ten-speed shifting), the user can replace the sleeve i of the rear hub 3 as needed to achieve the desired shifting effect, and each The size of the sleeve of the specification sleeve will vary depending on the shifting speed. The shape and length dimension of the sleeve will change. When the sleeve is replaced, the center line of the hub 3 and the center of the wheel rim will be replaced. The creator of the case uses the lock. Years of experience in similar products, continuous research and improvement experiments, and now finally developed has a practical value, and is enough to solve the conventional self-trailer T car replacement drum shift sleeve, also have to adjust the spokes of each spoke The problem of tension. [New content] 5 M314697 ... The main purpose of this creation is to provide a kind of bicycle drum structure. After that, the flower department I encloses the car heart. One side of the car core is sleeved with an inner hollow flower drum. Huagu = part and f left and right - Palin is connected with the car center, the other end of the car core is sleeved with an inner working sleeve, the left and right sides of the wire barrel are stored - the opposite is connected with the car center, the sleeve On the inner side, the ring gear of the ratchet ring is matched with the inner tooth of the hub, which can drive the drum to rotate and achieve the shifting effect, and a left cover is assembled on the left side of the car core. The first screw hole of the paste is locked to the screw on the right side of the car center, and the outer side cover is provided with a second screw hole for the second screw hole, by the length of the sleeve The design of the size 'makes the hub of the hub _ the center line of the rim can be scaled at a fixed distance, and when the sleeve of each shift specification is replaced, the tension of each strip is corrected. • _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ As shown in Fig. 3, after the creation of the bicycle, the structure of the drum is used, and the rear drum is connected with the spokes and the rim (not shown), which includes the ···k direction to the car 1G, the car 10 series A screw 11 is arranged on the right side of the pipe body which is _ empty at both ends. "Chemistry 20" is a hollow body that is pierced at both ends, and is placed on the left side of the car heart, and the left and right sides of the hub 20 are connected to each other by the Palin 21, so that The car core 10 is fixed, and the hub 20 is rotated. The hub 2 defines an opening 22, 23 on each of the right and left sides. The apertures of the openings 22, 23 are larger than the inner middle of the hub 2, and the opening on the 2 side. 23 is internally provided with a toothed ring 24. 6 M314697 left side cover 30, the left side cover 30 is sleeved in the opening on the left side of the car center 1 , and can rotate with the car core 10, and the left side cover 30 can The right side of the flower drum 2 培 Palin 21 is sealed. A sleeve 40 'the sleeve 40 is for the ends to pass through the butterfly, the fine tender _ spine, the ring (four) on the right side of the socket · ^ 豉 20 In the ring gear 24, the peripheral yarn of the ratchet ring 41 has a plurality of movable ratchet teeth, which can be engaged with the ring gear 24 of the hub 20 to drive the hub 2 to rotate in one direction, and the inside and outside of the sleeve 1 are borrowed. A pair of Palin 43 is connected to the car core 1〇, so that the sleeve milk can be freely rotated. The outer circumference of the sleeve 40 is axially divided into a plurality of concave and convex teeth 44; For the nine-speed and ten-speed shifting, the length of the sleeve 4〇 center line and the rim centerline c is L', so that the center line of the hub 20 and the rim centerline c are maintained at the county value a. Referring again to "Fig. 4", another type of sleeve 40a is used. The shifting speed of the sleeve 4〇a is a ten-speed shift. 'Because the latch 44 on the outer side of the sleeve 40a and the sleeve are slanted right _ the distance is longer' The length u of the center line of the sleeve 40a and the center of the rim is lengthened, and is assembled on the hub 2() by the positional dimension of the sleeve 4〇a, which is the center line and the wheel of the hub 2() The circle # center line c can be maintained at a predetermined value a, that is, the center line c of the rim does not change.右侧One right side cover 50' The right side cover 50# is adjacent to the inner side of the sleeve 4〇 to the first screw hole, and the right side is sleeved with the oil seal 52, and the sleeve 4 can be most: side The Palin 43 is sealed, and the right side cover is provided on the outer side of the 5G-second screw hole. ^ A stud 60, a screw 6 is disposed on the inner side of the stud 60, and the screw 61 is locked in the second screw hole 53 of the right side cover 5G. This prevents the right ship 5 () from retreating with the surplus From the outer side of the stud 60, a polygonal sleeve hole 62 is provided, and the sleeve hole (10) is provided for the wrench to be pulled. 7 M314697 Because the length of the bicycle 2 of the bicycle is as specified in the "Fig. 1", the sleeve 1 will have different tooth-clamping positions and lengths due to different shifting specifications, and - different shifting The sleeve 1 is arranged on the hub 3, which causes the distance between the center line of the hub 3 and the rim of the wheel and the center line to vary, and the present invention mainly controls the position of the latch 44 of the different shift specification sleeves 4〇, 40a. The different sleeves 40, 40a are assembled on the hub 20, and the center line positions of the latches 44 are different, so that the distance between the center line of the hub 2 and the center line c of the rim can be maintained at a predetermined value A, When the user replaces the sleeves 4〇 and 40a of different shifting speeds, the trouble of adjusting the tension of the spokes of the wheel can be eliminated. In summary, the creation has been sampled as a patent specification and schema content, and it has been proved by many times that it can achieve its intended purpose and efficacy. The practical value is quite competitive in the market. The inspection of the market and the publication of the publication of the same or similar products, according to the provisions of the Patent Law to the Office of the patent application. However, the above description is only a preferred embodiment of the present invention. When it is not possible to limit the scope of the creation of the creation, that is, the equal changes and modifications made by the original creation should be covered by this creation patent.
