The brake bushing 72 generates an axial displacement, " (here the steering sleeve portion 22 and the brake bushing 72 cooperate with the thread to be: preferably, but not limited to this type), so that the second brake The face 21 moves and abuts against the first brake surface 11 to achieve a braking state of mutual friction. As shown in FIG. 8, the fixed brake disc 10 and the axial displacement brake disc 20 may also be mounted on the outer position of the hollow cylindrical space 07 of the hub 06, as for the fixed brake disc 10 and the axial displacement. The operation principle and structure of the brake disc 20 to achieve the brakes are the same as those of the above embodiment, and therefore will not be described again. Efficacy Description: The fact that the creative effect is enhanced is as follows: The "Bike Wheel Brake Structure" disclosed in this creation mainly consists of the innovation of the brake disc, the axial displacement brake disc and the brake components - unique structure type The design of the wheel can be used to drive the axial displacement of the brake disc to generate axial displacement, so as to achieve the axial disc-shaped friction type of the wheel brake function against the friction fixed brake disc; The design of the structure of the easy-to-wheel hub brake makes the design of the conventional brake disc and the axial displacement brake disc as simple disc-shaped or block-shaped members, according to the conventional structure proposed in the prior art. Therefore, the manufacturing and processing technology level is very simple and facilitates mass production, and the assembly aspect can also be sequentially assembled from the end of the hub to facilitate and high efficiency, and the toroidal shape formed between the fixed brake disc and the axial displacement brake disc. The brake interface type has a frictional area that is no less than that of a conventional drum or clip-on brake interface; therefore, the skill of the creation is 9 M436630. Brake structure member to achieve greatly simplified, reduced weight and volume of the installation, producing quantized simpler, more convenient and Assembling both practical and progressive braking effectiveness and advantages of the preferred brake. The disclosures of the above embodiments are intended to specifically illustrate the present invention, and although the descriptions are made by specific terms, the scope of patents of the novel creation cannot be limited thereby; those skilled in the art can understand the creations" The spirit and principles are changed and modified to achieve the equivalent purpose, and - such changes and modifications shall be covered in the scope of the patent application scope as described later.
