Description

Technical Field

[0001] This utility model belongs to the field of motorcycle wheel technology, and specifically relates to a spoke-type vacuum tire wheel. Background Technology

[0002] Tubeless tires are tires without an inner tube. A 2-3 mm thick rubber sealing layer is added to the inner wall of the tire, and underneath this sealing layer is a self-adhesive layer made of a special mixture of uncured rubber. The airtight layers on the tire's inner wall and bead ensure good airtightness between the tire and the rim, thus replacing the function of a traditional inner tube. The outer tire also functions as an inner tube. After inflation, the bead seals tightly against the rim, effectively preventing air leakage.

[0003] Motorcycles are two- or three-wheeled vehicles powered by either fuel or electricity and steered by handlebars. They are characterized by their lightness, agility, and speed. Because motorcycle wheels need to meet the requirements of high speed, durability, comfort, and safety, spoked wheels have long been popular among motorcyclists due to their original retro style, high shock absorption performance, and varied rim designs. However, the load-bearing capacity of spokes still limits their susceptibility to breakage under high loads and alternating stress. Utility Model Content

[0004] The purpose of this invention is to provide a spoked tubeless tire wheel to address the aforementioned problems, thereby improving the limited load-bearing capacity of the spokes in existing spoked wheels and their tendency to break under high load conditions.

[0005] The technical solution adopted in this utility model is as follows: A spoked tubeless tire wheel, comprising the following:

[0006] The rim includes a first side and a second side of the rim that are disposed opposite to each other;

[0007] The wheel hub includes a first mounting plate near the first side of the rim and a second mounting plate near the second side of the rim;

[0008] The spoke support assembly includes a first spoke group and a second spoke group. One end of the first spoke group is connected to a first side of the rim, and the other end of the first spoke group is connected to an internal thread near a second mounting plate. One end of the second spoke group is connected to a second side of the rim, and the other end of the second spoke group is connected to an internal thread near a first mounting plate.

[0009] The rim and hub are connected by a spoke support assembly, with the first side of the rim and the first mounting plate located on one side of the hub, and the second side of the rim and the second mounting plate located on the other side of the hub.

[0010] Due to the above-mentioned structure, the spoke support assembly only bears axial load, and the rimmed motorcycle wheel can improve the wheel's load-bearing capacity, thereby increasing the service life of the spoke support assembly.

[0011] Furthermore, in order to evenly distribute the load-bearing capacity of the spoke support assembly, both the first spoke group and the second spoke group are provided with multiple spokes. Each spoke has a first end and a second end. The first end is provided with an upsetting head, and the second end is provided with an external thread. The first end of the spoke is connected to the rim through the upsetting head, and the second end of the spoke is connected to the hub through the external thread.

[0012] Furthermore, in order to adjust the torque between the external thread of the spoke and the internal thread of the hub, a flat square structure is provided near the first end of the spoke, which is used to snap the spoke in place; a square structure is provided near the second end of the spoke, which is used to adjust the torque.

[0013] Furthermore, in order to securely connect the spokes and the hub, the hub is provided with internal threads, and the second end of the spoke is fixed to the hub by connecting the external threads to the internal threads of the hub.

[0014] Furthermore, in order to securely connect the spokes and the rim, the rim is provided with a recess for accommodating the upsetting head, which is connected to the rim through the recess.

[0015] Furthermore, in order to provide more space for the installation of tubeless tires, multiple recesses are provided, and the recesses are evenly distributed in a ring along the edge of the rim. The number of recesses is set to 32+4n, where n=0,1,2,4,5.

[0016] Furthermore, in order to stably connect the first mounting plate and the second mounting plate to the wheel hub, a brake is provided on the wheel hub, and the first mounting plate and the second mounting plate are connected to the brake through screw holes.

[0017] Furthermore, in order to evenly distribute the load-bearing weight of the spoke support assembly, the spacing between two adjacent spokes is greater than 5mm.

[0018] Furthermore, in order to securely connect the spokes to the rim, the rim is also provided with a conical surface, and the upsetting head is set in the recess and abuts against the conical surface.

[0019] Furthermore, to prevent the spoke threads from loosening or falling off, the screw hole has a fine thread structure and anti-loosening retaining adhesive is added to the screw hole to prevent the connection between the spoke and the inner thread of the hub from loosening or falling off.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0021] 1. This utility model divides the spoke support assembly into two parts, which are respectively connected to the internal thread near the second mounting plate of the hub and the first side of the rim, and the internal thread near the first mounting plate of the hub and the second side of the rim; and the first end of the spoke is connected to the rim through an upsetting head, and the second end of the spoke is connected to the hub through an external thread. The spokes are only subjected to axial force, thereby improving the load-bearing capacity of the spokes and making them less prone to breakage under high load conditions.

[0022] 2. This utility model connects the spokes to both sides of the rim, thus freeing up the rim bead seat groove. A tubeless tire is then mounted on the rim bead seat groove. The tubeless tire has the characteristics of slow air leakage, high safety, good heat dissipation, long life, light weight, and low driving resistance. The rim bead seat makes the tubeless tire easy to install. Furthermore, the spokes are far away from the tubeless tire, avoiding the problem of air leakage caused by the spokes.

[0031] The present invention will now be described in detail with reference to the accompanying drawings.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] In existing tubeless wheels with external spokes, the spoke nut is located in a hole in the hub boss, making torque adjustment difficult and spoke installation and replacement relatively challenging. This invention eliminates the spoke nut component found in current tubeless wheels with external spokes, making spoke torque adjustment easier, and the recessed structure 103 with an opening further facilitates spoke installation and replacement.

[0034] like Figure 1 - Figure 4 As shown, this invention improves the load-bearing capacity of the wheel, thereby increasing the service life of the spokes. According to CAE analysis and experimental results, the wheel's load-bearing capacity reaches 268% of that of a conventional motorcycle wheel, and its type test life can reach 470% of the JASO T203 standard requirement. Therefore, the structure of this invention can be widely applied to high-performance, high-quality 400cc-1800cc series high-end motorcycles, and has high promotional and application value. Furthermore, due to the spoke distribution, tubeless tires can be easily installed, avoiding the safety hazards of tubeless tire leaks.

[0035] Example 1

[0036] like Figure 1 - Figure 2 As shown, one embodiment of this utility model is a spoked tubeless tire wheel, comprising the following:

[0037] The rim 100 includes a first rim side 101 and a second rim side 102 disposed opposite to each other;

[0038] The wheel hub 200 includes a first mounting plate 201 near the first side 101 of the rim and a second mounting plate 202 near the second side 102 of the rim;

[0039] The spoke support assembly 300 includes a first spoke group and a second spoke group disposed between the rim 100 and the hub 200. One end of the first spoke group is connected to the first side 101 of the rim, and the other end of the first spoke group is connected to an internal thread near the second mounting plate 202. One end of the second spoke group is connected to the second side 102 of the rim, and the other end of the second spoke group is connected to an internal thread near the first mounting plate 201.

[0040] Generally, a wheel has 40 spokes. Two adjacent spokes on the wheel belong to different groups. The 20 spokes on the first side 101 of the wheel rim are the first group of spokes, and the 20 spokes on the second side 102 of the wheel rim are the second group of spokes.

[0041] The rim 100 and the hub 200 are connected by a spoke support assembly 300, and the first side 101 of the rim and the first mounting plate 201 are located on one side of the hub 200, while the second side 102 of the rim and the second mounting plate 202 are located on the other side of the hub 200.

[0042] Its working principle is as follows: the first side 101 of the rim and the first mounting plate 201 are located on the same side of the rim 100 and the hub 200, and the two ends of the spoke support assembly 300 are set on different sides of the rim 100 and the hub 200. That is, the first spoke group and the second spoke group are cross-set near the rim 100, which can increase the load-bearing capacity of the spokes, make the spokes less prone to breakage, extend the service life of the wheel, and make riding a motorcycle safer.

[0043] Example 2

[0044] like Figure 4 As shown, in another embodiment of the present invention, the first spoke group and the second spoke group are each provided with multiple spokes. Each spoke is provided with a first end and a second end. The first end is provided with an upsetting head 301, and the second end is provided with an external thread 305. The first end of the spoke is connected to the rim 100 through the upsetting head 301, and the second end of the spoke is connected to the hub 200 through the external thread 305.

[0045] The purpose of setting up the upsetting head 301 is: the upsetting head 301 is used to connect the spokes to the recess 103 of the rim 100.

[0046] The second end of the spoke is configured with an external thread 305 structure, which is connected to the hub 200 through the thread, making it easy to fix the spoke, and the spoke has a straight structure.

[0047] The spokes must be installed in a way that does not interfere with the installation of the inner tube, and the spokes must not damage the inner tube.

[0048] Example 3

[0049] like Figure 4 As shown, in another embodiment of the present invention, a flat square structure 302 is provided near the first end of the spoke, which is used to snap the spoke in place; a square structure 304 is provided near the second end of the spoke, which is used to adjust the torque.

[0050] The flat square structure 302 is used to facilitate the spokes to be inserted into the rim opening recess 103, and the square structure 304 adjusts the torque between the spoke external thread 305 and the internal thread 203 on the hub 200; thereby making the connection between the spokes and the hub 200 and the rim 100 more convenient and secure.

[0051] Example 4

[0052] like Figure 2As shown, in another embodiment of the present invention, the hub 200 is provided with an internal thread 203, and the second end of the spoke is connected and fixed to the hub 200 by an external thread 305 and the internal thread 203 of the hub 200.

[0053] One end of the spoke is connected to the hub 200 by inserting one end into the internal thread 203 of the hub 200 and connecting it to the internal thread 203 via the external thread 305, thus achieving the connection between the spoke and the hub 200. The advantages of threaded connection are: easy disassembly and tight engagement.

[0054] Example 5

[0055] like Figure 2 As shown, another embodiment of the present invention is that the rim 100 is provided with a recess 103, the recess 103 is used to accommodate the upsetting head 301, and the upsetting head 301 is connected to the rim 100 through the recess 103.

[0056] The other end of the spoke is provided with an upsetting head 301, and the other end of the spoke is connected to the rim 100. A recess 103 is provided on the rim 100, and the upsetting head 301 is connected to the rim 100 by extending into the recess 103. By providing a recess 103 on the rim 100 that matches the upsetting head 301, the upsetting head 301 is matched with the recess 103, which facilitates the fixing of the spoke.

[0057] Furthermore, after the spokes are fitted into the recess 103, a sealing strip with a decorative style can be fitted.

[0058] Example 6

[0059] like Figure 1 As shown, another embodiment of the present invention is that the pits 103 are provided in multiple ways, and the pits 103 are evenly distributed in a ring along the edge of the rim 100. The number of pits 103 is set to 32+4n, where n=0,1,2,4,5.

[0060] By setting recesses 103 on the rim 100, the position of each spoke does not affect the normal operation of the wheel while meeting the optimal range of spoke load-bearing capacity. Therefore, the number of recesses 103 is set to 32+4n. The spokes are evenly arranged in a fan shape, and the left and right spokes are distributed alternately in the wheel axle section. The distance between two adjacent spokes is greater than 5mm, which can improve the load-bearing capacity of the wheel.

[0061] Example 7

[0062] like Figure 1 As shown, another embodiment of the present invention is that a brake mounting plate is provided on the wheel hub 200, and the first mounting plate 201 and the second mounting plate 202 are connected to the brake through the screw hole 204.

[0063] The first mounting plate 201 and the second mounting plate 202 are disposed on both sides of the wheel rim 100. In order to brake the wheel in an emergency during rotation, the first mounting plate 201 and the second mounting plate 202 are connected to the brake through the screw hole 204.

[0064] Example 8

[0065] like Figure 3 As shown, in another embodiment of the present invention, the rim 100 is also provided with a conical surface 104, and the upsetting head 301 is disposed in the recess 103 and abuts against the conical surface 104.

[0066] The upsetting head 301 is provided with an upsetting head corner 303, which is a rounded corner. Within a certain range, the rounded corner can minimize the stress concentration of the spoke upsetting head 301 and improve the impact resistance and load-bearing capacity of the spokes.

[0067] The spokes are connected to the rim as follows: an upsetting head 301 is provided at one end of the spokes near the rim 100, and an open recess 103 and a conical surface 104 are provided on the rim 100. The upsetting head 301 abuts against the conical surface 104 of the mounting hole near the open recess 103 of the rim 100, thereby fixing the spokes to the rim 100.

[0068] The circumferentially oriented recess 103 on the rim 100 facilitates the assembly and replacement of the spokes. To further accommodate tubeless tires, both the first side 101 and the second side 102 of the rim are provided with rim recesses 103 and conical surfaces 104. The upsetting end 301 of the spoke, closest to the rim 100, connects to the recesses 103 and conical surfaces 104. By expanding the mounting space through the rim design, the spokes are moved further away from the tubeless tire mounting position, thus mitigating the safety hazard of air leakage after installing a tubeless tire.

[0069] Example 9

[0070] Based on the foregoing embodiments, the present invention can also adopt the following configuration: in order to improve the mechanical strength performance of the rim 100, the rim 100 provided in this embodiment uses "forged aluminum + spinning + solution aging" in the material selection, which can effectively guarantee the mechanical strength of the rim 100.

[0071] In order to improve the mechanical strength performance of the wheel hub 200, the wheel hub 200 provided in this embodiment uses "forged aluminum + T6 treatment" in material selection, which can effectively guarantee the mechanical strength of the wheel hub 200.

[0072] In order to improve the mechanical strength performance of the spoke support assembly 300, the spoke support assembly 300 provided in this embodiment uses high-strength alloy materials in the material selection, which can effectively ensure the mechanical strength of the spoke support assembly 300.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
