Description

Technical Field

[0001] This utility model relates to the field of hub disc brake technology, specifically an improved hub disc brake mounting structure. Background Technology

[0002] Traditional disc brake hubs use a full circle of serrated teeth or a hollowed-out circle at the center of the serrated teeth, which makes it difficult to simultaneously meet the requirements of lightweight design and installation strength.

[0003] The above technical conditions also have some drawbacks: the traditional hub disc brake has a full circle of serrated teeth. This structure is stable and reliable, but it is relatively bulky. Its application in carbon fiber bicycles with high weight requirements is not effective and is not conducive to the lightweight design of bicycles.

[0004] Based on this, this utility model designs an improved hub disc brake mounting structure to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an improved hub disc brake mounting structure to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an improved hub disc brake mounting structure, including a bottom bracket mounting cylinder, wherein an upper mounting part and a lower mounting part are provided on the bottom bracket mounting cylinder, a limiting ring is connected to the upper end of the bottom bracket mounting cylinder, and multiple upper tooth blocks and lower tooth blocks are alternately arranged on the outer wall of the limiting ring.

[0007] By adopting the above technical solution, the misaligned ring saw teeth can retain strength to a great extent while achieving lightweighting.

[0008] Preferably, there are four sets of upper and lower tooth blocks, wherein the length of the upper tooth block is 6A and the length of the lower tooth block is 7A.

[0009] By adopting the above technical solution, the layout of the four sets of tooth blocks optimizes the stress distribution, reduces stress concentration, and improves structural durability and installation stability.

[0010] Preferably, there are six sets of both upper and lower tooth blocks, wherein the length of the upper tooth block is 4A and the length of the lower tooth block is 4A or 5A.

[0011] By adopting the above technical solution, the six-group tooth block design further evens out the load, achieving a balance between lightweight and strength, and is suitable for high-frequency use scenarios.

[0012] Preferably, there are eight sets of both upper and lower tooth blocks, wherein the length of the upper tooth block is 3A or 4A, and the length of the lower tooth block is 3A or 4A.

[0013] By adopting the above technical solution, the eight sets of tooth blocks increase the number of meshing points, improve the anti-torsion performance and installation accuracy, and ensure that the disc brake remains firm in a vibration environment.

[0014] Preferably, the number of upper and lower tooth blocks is twenty-six sets, and the length of both upper and lower tooth blocks is A.

[0015] By adopting the above technical solution, the twenty-six sets of tooth blocks maximize the tooth block density, ensuring extremely high stress uniformity and overall strength, making it suitable for extreme load conditions.

[0016] In summary, this application has the following beneficial technical effects: the staggered tooth block design on the limiting ring significantly improves the installation firmness, fatigue resistance and service life of the hub disc brake, while reducing the overall weight and facilitating installation and maintenance; multiple tooth block configuration schemes can adapt to different vehicle models and load requirements, and have wide applicability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0022] An improved hub disc brake mounting structure includes a bottom bracket mounting cylinder 1, on which an upper mounting part 2 and a lower mounting part 3 are provided. The bottom bracket mounting cylinder 1 can be fixedly installed near the bicycle disc brake. A limiting ring 4 is connected to the upper end of the bottom bracket mounting cylinder 1. Multiple upper toothed blocks 5 and lower toothed blocks 6 are staggered on the outer wall of the limiting ring 4. Through the staggered arrangement, the strength is preserved to the maximum extent while achieving weight reduction. Its unique structure has better performance.

[0023] Furthermore, refer to Figure 2 There are four sets of upper tooth blocks 5 and four sets of lower tooth blocks 6. The length of upper tooth block 5 is 6A, and the length of lower tooth block 6 is 7A, where A represents the length of one unit tooth block. (Refer to...) Figure 5 As shown, there are a total of 52 unit teeth on the outer annular serrations of the limiting ring 4.

[0024] Furthermore, refer to Figure 3 There are six sets of upper tooth blocks 5 and lower tooth blocks 6. The length of upper tooth block 5 is 4A, and the length of lower tooth block 6 is either 4A or 5A. The total length of all upper tooth blocks 5 and lower tooth blocks 6 is 52A, which makes the force distribution more uniform.

[0025] Furthermore, refer to Figure 4 There are eight sets of upper tooth blocks 5 and lower tooth blocks 6. The length of upper tooth block 5 is 3A or 4A, and the length of lower tooth block 6 is 3A or 4A. The total length of all upper tooth blocks 5 and lower tooth blocks 6 is 52A, which further improves the force-bearing effect.

[0026] Similarly, there are twenty-six sets of upper toothed blocks 5 and lower toothed blocks 6, with the length of upper toothed blocks 5 and lower toothed blocks 6 both being A, which can increase the force distribution effect of the hub disc brake.

[0027] The implementation principle of this embodiment is as follows: the structure is fixed to the bicycle frame by the upper mounting part 2 and the lower mounting part 3 on the bottom bracket mounting cylinder 1. The staggered upper tooth block 5 and lower tooth block 6 on the limiting ring 4 mesh with the disc brake component. The staggered layout between the tooth blocks disperses the impact force, while reducing the use of materials, achieving a combination of lightweight and high strength. During operation, the staggered design of the tooth blocks effectively prevents loosening and ensures that the disc brake remains stable when riding at high speed or braking.
