Embodiment
[0020] Embodiment: a rear hub ratchet cylinder with improved structure, including a ratchet group 1, a locking member 2 and a clip spring 3, and an annular concave groove 5 is formed on the inside of one end of the ratchet wheel 4 of the ratchet group 1, The inside of the lock piece 2 is formed with an inner hole for the center 12 to pass through, one end of the lock piece 2 forms a connection end that can be fixedly connected with the hub shell 9, and the snap spring 3 can be fixedly sleeved on the other end of the lock piece 2 On the outside of the circumference, the outer wall of the circlip 3 can be tightly clamped in the ring-shaped concave groove 5 on the inner wall of the neutron 4 of the ratchet wheel. The combined connection facilitates the processing and manufacturing of the ratchet set 1 and the locking member 2, with low processing difficulty and low processing cost, and the split structure is convenient for assembly and subsequent maintenance, convenient maintenanc...

The invention discloses a back hub ratchet cylinder with an improved structure. The back hub ratchet cylinder comprises a ratchet assembly, a locking part and a clamp spring, wherein the inner side ofone end of a ratchet inner core of the ratchet assembly is provided with an annular inward-concave clamp groove; an inner hole is formed in the inner side of the locking part, and a bicycle core penetrates through the inner hole; one end of the locking part forms a connecting end which is fixedly connected with a hub outer casing; the clamp spring is fixedly sheathed on the outer side of the circumference of the other end of the locking part; the outside wall of the clamp spring is tightly clamped into the annular inward-concave clamp groove at the inside wall of the ratchet inner core. The back hub ratchet cylinder has the advantages that the ratchet assembly and the locking part are connected together by the clamp spring, and are separately processed; the processing is simple and convenient, and the processing cost is low; the damaged locking part can be singly replaced in the use process, and the replacement of the whole ratchet assembly is not needed, so that the maintenance costis reduced; when the locking part and the hub outer casing are installed, the operation of the ratchet assembly is not needed, and the installation is convenient.
Description
technical field [0001] The invention relates to a bicycle hub, in particular to a rear hub ratchet cylinder with improved structure. Background technique [0002] In the current rear hub ratchet barrel structure, the ratchet set and the hub barrel body are connected as one structure, which is difficult to design and process, and the cost is high. Damage during use will directly lead to the scrapping of the entire ratchet set. The cost of use is high, which is not conducive to maintenance. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides a rear hub ratchet cylinder with an improved structure, which is convenient to process and manufacture, has low manufacturing cost, and is convenient for subsequent maintenance. [0004] The technical solution adopted by the present invention in order to solve the technical problem is: a rear hub ratchet barrel with improved structure, including a ratchet group, a locking me...
