[0051] The use process of the bidirectional clutch structure is as follows:

[0052] When the flywheel main body 2 drives the input bevel gear 4 to rotate forward, the input bevel gear 4 drives the first tension spring 403 to elongate, thereby driving the large retainer 401 to move through the first tension spring 403, and the large retainer 401 drives the first roller 402 to move in the narrow distance area between the first clutch block 103 and the input bevel gear 4 in the first one-way missing groove 5. After the first roller 402 moves, the first roller 402 will be clamped between the first clutch block 103 and the input bevel gear 4 under the action of the first one-way missing groove 5, so that the input bevel gear 4 drives the first clutch block 103 to move together, thereby driving the hub main body 1 to rotate forward. In this process, the output bevel gear 6 rotates reversely under the transmission of the reversing bevel gear 301 and the input bevel gear 4, at this time, the second tension spring 603 rotates together with the output bevel gear 6, so that the small retainer 601 keeps the same direction and speed movement with the output bevel gear 6, at this time, the second roller 602 moves in the wide distance area between the second clutch block 104 and the output bevel gear 6, so that the first roller 402 cannot clamp the second clutch block 104 and the output bevel gear 6 together, that is, the power cannot be transmitted to the hub end cover 101 and the hub main body 1 through the output bevel gear 6, thereby avoiding interference;

[0053] If the flywheel body 2 drives the input bevel gear 4 to reverse, the first tension spring 403 reverses together with the input bevel gear 4, so the big retainer 401 keeps moving with the input bevel gear 4 in the same direction and at the same speed, thus the first roller 402 can only move in the big retainer 401 and cannot be stuck between the first clutch block 103 and the input bevel gear 4, so when reversing, the power is converted to the output bevel gear 6 through the reversing bevel gear 301, so that the output bevel gear 6 rotates forward, when the output bevel gear 6 rotates forward, the input bevel gear 4 drives the second tension spring 603 to elongate, thereby driving the small retainer 601 to move through the second tension spring 603, and the small retainer 601 drives the second roller 602 to move in the second one-way missing slot 7; when the second roller 602 moves to a certain position, it will be stuck between the second clutch block 104 and the output bevel gear 6, thereby driving the second clutch block 104 to move together, and the second clutch block 104 drives the hub body 1 to rotate forward through the hub end cover 101.
