New description: [New technical field] This creation is about a ratchet structure, especially the hub part, which has the ability to replace the positive and negative transmission directions. Used in bicycle wheels for convenient assembly and stabilization [Prior Art] The bicycle hub ratchet structure is mainly installed in the flower valley, which is a one-way transmission when the fish wheel shaft rotates. In other words, the ratchet makes the car There is a power transmission state of work, when the pedal is not stepped on, the ratchet structure shell 1 does not work to produce miscellaneous 'money wheels will continue to produce rotation. The bicycle ratcheting series is mostly composed of the pawl on the peak wheel and the 4 soft components of the ring. According to the direction of the transmission, it can be divided into "one-way" = two-way "two kinds" of which "one-way" It means that the ratchet structure is only suitable for the two = direction of rotation, and the "two-way" type of ratchet structure is suitable for both the clockwise and counterclockwise directions of rotation. Since the chain device of the bicycle is generally installed on the right side of the vehicle body, the direction of the movement of the ratchet structure must be the same as the direction of the vehicle body, that is, the direction of the rider's pedaling; however, because of the ride of the rider Habits are different, or some special bicycle models have the need to install the chain device on the left side of the car body, so that the ratchet structure can be driven by the left chain device and the right chain device. _ Developed a "two-way" ratchet structure. According to the traditional Chinese bicycle, the "one-way" bicycle has a ratchet structure, such as the 3rd M376441 095137512 domestic inspection.

[New content] In the temporary configuration of the failure, the structure is mainly in the bicycle. - Foot mechanism jumps fine (four) Health (four) force shot to make the resistance piece drive the material element to tear the scale element to persuade and then improve the king, the structure of the "claw and component replacement wire position, you can reach the left The purpose of those right drive. In the "two-way" flower wheel structure for the step-by-step reading, the structural elastic element and the / end is maintained abutting on the ratchet; however, the volume of the magazine is small and its use The number also needs to be matched with the number of the claws and configured in groups. When repairing or oiling, if one of the elastic elements is accidentally lost, the set of claws cannot maintain the ratchet outwards and cannot generate the transmission. At the same time, the action is f-actuated and the claws are loose. The noise is generated, so that the whole set of ratchets = white can not be used and the entire group is replaced. This shows that the hybrid component is the missing one in the whole group of ratchet ratchet structures. The necessary components are not necessary; therefore, the creator of this case provides another "two-way" flower wheel structure for the above problems. (Technical means to solve the problem) % There is a clock here, this design reveals the easy-to-replace direction flower hub ratchet structure, which is between the valley seat and the axle, which includes: a ratchet ring, which is attached to The 'turning ring' in the ^ Valley is provided with a plurality of ratcheting gear transmission sets, which have a set of sighs on the ratchet shaft - the ratchet is provided, and the miscellaneous wheel is provided with a miscellaneous concave groove to /, a transmission groove and At least a positioning slot, which is respectively provided with a transmission block and a certain cymbal and can be rotated by (4), wherein the transmission block has a transmission ,, which is stuck to the _ _, each rotating block and The positioning age is tightly bundled on the ratchet seat by an elastic beam ring; by the above-mentioned members, the paste is adjacent to each other and the setting of the transmission groove and the position groove can exchange the transmission blocks and the positioning ghosts It can be switched to produce the rotation direction of the transmission. Even if one set of fixed blocks and transmission blocks are set up, the overall 彳b valley ratchet can still reach the transmission _ and continue to use unaffected' while providing fast assembly and stable combination. Therefore, the overall structure can be convenient and practical. (Compared with the efficacy of the prior art) The main purpose of the creation is to provide a structure that is easy to change direction, and the structure of the tilting and squatting block of the ratcheting system And the two blocks, the whole trough ratchet still achieves the transmission effect and continues to use, without affecting the transmission.

For the restoration operation state of each of the transmission block (44) and the elastic bundle ring (46), referring to the fifth to sixth figures, firstly, the reverse generation transmission action is taken as an example, when the elastic collar (46) When the drive block (44) and the positioning block (45) are collectively tightened on the ratchet seat (41), the elastic brace (46) provides an inward elastic force to position the clamp block (45). The rotation occurs in the groove (43) until the balance state of the force, and the transmission block (44) is also rotated by the internal elastic force in the transmission groove (42) until the front end of the transmission tooth (441) abuts against the reverse The card is in a locked state to the abutting surface (312); in this case, the transmission group (4〇) is reversely rotated to have a transmission force. When the transmission group (10) rotates in the forward direction or stops rotating, the transmission window (441) toward the positive position of the aged part (3)), the yoke to the side of the ratchet portion (31) and the raised portion of the rim, such as the continuous rotation, the transmission block (10) is subjected to the elastic collar (46) The feeding force is reversed - the angle, the transmission secret 41) immediately falls into the groove of the ratchet portion (31), and produces an acoustic sound, and the transmission tooth (4) 爬 so climbs up and down The ratchet portion (8) cannot be gambling, so it is an idling state that does not have a transmission force. The creation is preset when the reverse rotation of the transmission group (40) is a transmission force, please refer to the seventh diagram, the transmission block (44) and the granule (45) are grouped together. The four rings are disposed on the ratchet seat (4)), and each of the transmission blocks (10) and the positioning block (45) are respectively disposed in each of the transmission slots (42) and the positioning slots, and the elastic collars are 46) tightening is positioned on the ratchet seat (: 41), and the transmission block (44) is elastically rotated by the inner diameter of the elastic collar (46) to rotate the transmission tooth (441) outward to abut On the reverse abutment surface (312); therefore, when the sprocket seat (47) is driven to rotate in the opposite direction, the ratchet seat (μ) and each of the transmission blocks (44) and the positioning thereon are driven. The block (45) rotates synchronously, and the driving tooth (441) pushes the reverse abutting surface (gig) to further drive the ratchet ring (3丨) and the rim hub (10) to synchronously generate a reverse rotation. Then, the wheel also rotates in the opposite direction. When the chain stops driving the sprocket seat (47), the sprocket holder (47), the ratchet seat (41), the transmission block (44), and the positioning block (45) stop rotating, but the thorn The ring gear (30) and the flower hub (1〇) are continuously synchronized by the inertia law to generate a reverse rotation. At this time, the gear teeth (441) are between the concave and convex portions (31). The Tata sound is emitted when it touches up and down, and the M376441 state is not in the form of a transmission, so the wheel still rotates in the opposite direction. When the forward rotation of the transmission group (4〇) is pre-removed to have a transmission force, please refer to the eighth figure, and a transmission block (44) and a positioning block (45) are grouped together. The four sets of rings are disposed on the ratchet seat (41), and each set of the transmission block (44) and the positioning block (45) are respectively disposed in each of the positioning slots (43) and the transmission slots (42). And the elastic beam ring (46) is tightly positioned on the ratchet seat (μ), and the transmission block (44) is elastically rotated by the inner diameter of the elastic beam ring (46) to make the transmission tooth (441) Rotating outwardly to abut against the forward abutment surface (311), in other words, the transmission block (44) is disposed in the positioning groove (4)), and the positioning block (45) is disposed in the transmission groove ( 42), in the reverse rotation transmission described above, each of the transmission block (44) and the positioning block (45) are in a mutually displaced state. Therefore, when the sprocket seat (47) is rotated forward by the chain drive, the bellows drives the ratchet seat (41) and each of the transmission block (44) and the positioning block (45) to rotate synchronously. The driving tooth (441) pushes the forward abutting surface (311) and simultaneously drives the ratchet ring (30) and the flower hub (10) to generate a positive rotation synchronously, and the wheel also rotates in a positive direction and turns into a When the chain stops driving the chain holder (47), the ratchet ring (3〇) and the flower hub (10) are continuously synchronized to generate a positive rotation due to the law of inertia, and the transmission tooth (441) is in the concave and convex Each of the ratchet portions (31) is in contact with each other up and down to emit a tower sound, and is in a state of being in a state of rotation, so that the wheel is still rotating in the forward direction. In the present invention, each of the positioning block (45) and the transmission block (44) are respectively disposed in each of the adjacent (42) and positioning slots (4), by replacing the transmission block (44) and the positioning. The position of the block (45) can be selected such that the transmission tooth (441) is pushed against the forward abutment surface (311) or the reverse abutment surface (312) of the 11 M376441, and the "two-way" flower hub ratchet is completed. The structure is designed to provide the rider with the chain drive structure to change the left and right sides of the car body without additional purchase. Moreover, the creation is based on the elastic wire (10)). The transmission block (44) and the positioning block (45) are located on the ratchet seat (41). The overall structure is simple, and the assembly is easy and fast, which can greatly reduce the manufacturing cost. The creation of the positioning block (45) and the transmission block (44) of the group is tightly bundled by an elastic bundle ring (46), even if one of the positioning blocks (45) * and the transmission block are less assembled ( 44) 'Or one of the positioning block (45) or the transmission block (44) is lost, and the remaining positioning blocks (45) and the transmission block (44) can still be rotated to push the ratchet ring (30) to reach The transmission acts and continues to be used without affecting the transmission; at the same time, the positioning block (45) has an expanded state that maintains the elastic collar (46) to a predetermined extent, in other words, when the elastic collar (46) is actuated by elastic expansion and contraction The range of the expansion and contraction is limited, and the transmission tooth (441) can be further moved up and down on the ratchet portion (31), and the movement of the transmission block (44) is faster, so that the transmission is performed. The transmission of the moving group (40) is more sensitive, and the noise generated by the transmission tooth (441) due to the smaller fluctuation of the up and down is smaller. In the present invention, the ratchet seat (41), the transmission block (44) and the positioning block (45) are disposed at the position of the elastic bundle ring (46), and the tightening groove (411) (442) is commonly ring-connected ( 451), the elastic band (46) is provided to be embedded in the position of the set, and is not easy to loosen. In summary, the "easy-to-replace direction flower hub ratchet structure" disclosed in the present invention provides a ratchet structure with two directions of rotation, which can be used for phase 12 M376441.
