Description
TECHNICAL FIELD
[0001] The present application relates to the field of vehicle accessories, in particular to a preparation method of a connected fiber spoke and a wheel preparation method. BACKGROUND
[0002] The spoke is a commonly used vehicle accessory for connecting the rim and the hub, especially in small motor vehicles such as bicycles, motorcycles, etc., and has a large number of applications. The spoke accessory meets the performance requirements of high tensile strength and good fatigue performance. Traditional steel wire spokes are heavy in weight and low in tensile strength, and do not have a competitive advantage. Therefore, fiber spokes with more excellent performance are invented.
[0003] Traditional bicycle spokes are mostly steel wire spokes, which are heavy in weight and low in strength. Therefore, a replacement scheme using carbon fiber spokes has appeared in the prior art, which solves the problems of strength and weight of traditional spokes to some extent, but the problems of easy deflection of spokes when the tension changes and weak overall rigidity still exist.
[0004] The existing carbon fiber integrated long spoke is usually connected with the hub at one side of the spoke, and the two ends of the spoke are connected with the rim. Although it solves the problems of easy deflection of spokes when the tension changes and weak overall rigidity to some extent, when multiple spokes are installed in sequence, the centripetal force of the multiple spokes does not locate at the center of the rim due to the inconsistent tensioning force of the multiple spokes, which leads to eccentricity of the hub, i.e. the technical problem of difficult installation of spokes.

[0016] In one embodiment, the long fiber rod is made of carbon fiber material.
[0017] In one embodiment, before the resin is coated on the fiber rod and the fiber spoke is pre-shaped in step S4, the method further includes: step S40, preparing two short fiber rods, placing the two short fiber rods in the separation portion, and abutting the two ends of each short fiber rod against the two long fiber rods, respectively; and the coating of the resin on the long fiber rod and the short fiber rod and the pre-shaping of the fiber spoke in step S4 includes: coating the resin on the long fiber rod and the short fiber rod and pre-shaping the fiber spoke.
[0018] In one embodiment, the curing of the pre-shaped fiber rod prepared in step S4 to form a fiber spoke in step S5 specifically includes: placing the pre-shaped fiber rod in a forming mold, and curing the resin and the fiber to form an integrated body by high temperature in the forming mold, thereby preparing the fiber spoke; and the short fiber rod is connected to the long fiber rod as a whole after being cured by high temperature with the resin.
[0019] In one embodiment, the long fiber rod and the short fiber rod are both made of carbon fiber material.
[0020] The application further provides a wheel preparation method, which includes the preparation method of the connected fiber spoke as described above, and further includes:
[0021] Step S100, fixing a metal connecting piece to the two ends of the connected fiber spoke, which is used to connect the fiber spoke with the rim;
[0022] Step S200: connecting the fiber spoke to the hub, specifically, connecting the bifurcated part of the fiber spoke to the end face boss of the hub, and gluing the fiber spoke and the hub together in sequence;

Those of ordinary skill in the art should be able to understand other possible implementations and the advantages of the present application in conjunction with these. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.
[0047] The present application is further illustrated by the accompanying drawings and specific embodiments.
[0048] Example 1
[0049] like Figures 4-10 As shown, the first embodiment of the present invention provides an integral fiber spoke 10, wherein the fiber spoke 10 has a forked portion 110 formed in the middle, which is used to connect with the hub 20 of the wheel. A spoke arm 120 is connected to each end of the forked portion 110, and the two ends of the fiber spoke 10 are used to connect with the rim 30 of the wheel. The fiber spoke 10 has two side arms 111 formed at the forked portion 110, and two connecting sections 130 are provided within the forked portion 110, with each end of the connecting section 130 corresponding to one of the side arms 111. When the hub 20 and all the fiber spokes 10 are integrated, the overall rigidity of the wheelset is increased, and spoke deflection is avoided; furthermore, the forked portions 110 of all the fiber spokes 10 can be connected to the hub first, making it easier to adjust the centripetal force of multiple spokes to be located at the center of the rim during installation, thus making spoke installation more convenient.
[0050] like Figures 1-6 As shown, in order to manufacture the fiber spokes as described above, the first embodiment of the present invention provides a method for preparing an integral fiber spoke 10, which includes the following steps:
[0051] Step S1: Prepare two long, strip-shaped fiber rods 1 according to a preset size. The prepared fiber rods 1 are dense. Optionally, the two long, thin fiber rods 1 can be formed by hand-rolling. Alternatively, the two long, thin fiber rods 1 can be prepared using mechanized equipment.
[0052] Step S2: Arrange two long fiber rods 1 side by side, and bring the two ends of the two long fiber rods 1 together, keeping them separated in the middle, as shown. Figure 2 As shown.
[0053] In step S3, the two ends of the two long fiber rods 1 that are joined together are respectively integrated into a single fiber arm 12. The fiber arm 12 is dense, and the two long fiber rods 1 are kept separated in the middle to form a separation section 11. The two fiber arms 12 are located at the two ends of the separation section 11. Optionally, the two ends of the two long fiber rods 1 that are joined together can be integrated into dense fiber arms 12 by hand. Alternatively, a mechanized device can be used to integrate the two ends of the two long fiber rods 1 that are joined together into dense fiber arms 12.
[0054] Step S4: Coat the fiber rod with resin and pre-shape the fiber spokes. The fiber rod can be placed in a pre-forming fixture and coated with resin to pre-shape the fiber spokes. Optionally, the coating resin is epoxy resin.
[0055] Step S5, the preformed fiber spoke bar prepared in step S4 is cured and formed, thereby preparing the fiber spoke 10. Specifically, the preformed fiber spoke bar can be placed in a forming mold, and the resin and the fiber are cured and formed into one body in the forming mold through high temperature, thereby preparing the fiber spoke 10. The two ends of the fiber spoke 10 are used to be connected with the rim of the wheel. The fiber spoke 10 is formed with a bifurcated portion 110 in the middle, and the bifurcated portion 110 is used to be connected with the hub of the wheel. The two ends of the bifurcated portion 110 are respectively connected with a spoke arm 120.
[0056] In the embodiment, the two long fiber bars 1 are kept separated in the middle to form a separation portion 11, and two fiber long arms 12 are respectively located at the two ends of the separation portion 11, thereby forming a connected fiber spoke 10. The middle of the prepared fiber spoke 10 is formed with a bifurcated portion 110, and the bifurcated portion 110 is used to be connected with the hub, so that when the hub 20 is connected with all the fiber spokes 10, the overall rigidity of the wheel set can be increased, and the spoke deflection can be avoided. Moreover, the bifurcated portions 110 of all the fiber spokes 10 can be connected with the hub first, so that the centripetal force of the multiple spokes during installation can be more conveniently adjusted to be located at the center of the rim, and the installation of the spokes is more convenient. In addition, the appearance of the wheel set is also improved.
[0057] In the embodiment, before the fiber spoke bar is coated with resin and preformed in step S4, the method further comprises: step S40, two short fiber bars 2 in a dense state are prepared, the two short fiber bars 2 are placed in the separation portion 11, and the two ends of each short fiber bar 2 are respectively abutted against the two long fiber bars 1, as shown in Figure 3 In step S4, the fiber spoke bar is coated with resin and preformed, which comprises: the long fiber bar 1 and the short fiber bar 2 are both coated with resin and preformed.
[0058] In the embodiment, the resin and the fiber are cured and formed into one body through high temperature in step S5, which further comprises: the short fiber bar 2 is connected with the long fiber bar 1 as one body after being cured and formed with the resin through high temperature. The short fiber bar 2 is connected with the long fiber bar 1 as one body, which can strengthen the overall strength of the fiber spoke after being formed. Moreover, when the fiber spoke is connected with the hub of the wheel through the bifurcated portion, the connecting segment 130 formed at the short fiber bar 2 can play a clamping role, thereby playing a role of auxiliary preventing the fiber spoke from rotating relative to the hub.
[0059] Preferably, the long fiber rod 1 and the short fiber rod 2 are made of carbon fiber material. It should be noted that the embodiment is described by taking the fiber rod made of carbon fiber material as an example. However, it is also feasible to use fiber rods made of other high-strength and high-modulus fibers, which can be expected by those skilled in the art. The high-strength and high-modulus fiber refers to a high-performance fiber material defined under the standard in the industry, specifically a synthetic fiber or a natural fiber with a strength greater than 10 CN / dkex and a modulus greater than 200 CN / dkex.

A spoke arm 120B is connected to each end of the forked portion 110B.
[0068] Preferably, the long fiber rod 1 is a carbon fiber spoke. It should be noted that this embodiment uses a carbon fiber rod as an example. However, those skilled in the art will appreciate that using fiber rods made of other high-strength, high-modulus fibers is also a feasible solution.
