Description

Technical Field

[0001] This application relates to the field of bicycles, and more particularly to a hub assembly, wheel, and bicycle. Background Technology

[0002] With the widespread use of bicycles in sports and commuting, the performance requirements for their key components are increasing. As the core component connecting the wheel and frame, the hub's structural stability directly affects riding safety and comfort. Traditional single-sided hubs have significant shortcomings in anti-loosening performance during assembly and use. Because bicycles are frequently stopped and started, and operate on bumpy roads, the hub assembly is often subjected to continuous vibration and impact. This can cause the axle to loosen relative to the hub body during riding, resulting in axial movement and wheel wobble. This not only increases maintenance frequency but also poses safety hazards, affecting riding reliability and user experience. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a hub assembly, wheel and bicycle.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides: A hub assembly, comprising: The hub body has a first mounting hole, and a rotating support is provided in the first mounting hole. The rotating support is interference-fitted into the first mounting hole. A shaft body, which is rotatably mounted in the first mounting hole via a rotating support member; A retaining ring is sleeved on the shaft and abuts against the rotating support member; Fasteners are provided on the shaft.

[0005] Furthermore, the end face of the retaining ring facing away from the rotating support member is provided with a first anti-slip texture.

[0006] Furthermore, the shaft is fitted with a spring washer, which is located on the side of the fastener facing the rotating support.

[0007] Furthermore, an anti-slip pad is also fitted onto the shaft, and the anti-slip pad is located on the side of the spring pad facing the rotating support.

[0008] Furthermore, the anti-slip pad has a second anti-slip texture on the side facing the rotating support.

[0009] Furthermore, the hub body includes a sleeve and a convex ring. The sleeve has the first mounting hole, and the convex ring is disposed on both sides of the circumferential surface of the sleeve. The convex ring is provided with a plurality of second mounting holes distributed along the axis of the sleeve.

[0010] Furthermore, the shaft includes an integrally formed smooth rod portion and a threaded portion, and the fastener is disposed on the threaded portion.

[0011] This application provides a wheel, comprising: The hub assembly described in any of the above statements; The wheel body has spokes on it, and the wheel body is connected to the hub body through the spokes.

[0012] This application also provides a bicycle, including: The wheels mentioned above; Mounting bracket, on which the wheel is mounted.

[0013] Furthermore, the mounting bracket includes a frame body having a third mounting hole, a sleeve being disposed within the third mounting hole, and the sleeve having a fourth mounting hole extending through it along its axial direction.

[0014] This application, by setting up a hub body, axle, retaining ring, and fasteners, and using the retaining ring to abut against the rotating support, and then using the fasteners to axially limit the axle, effectively prevents the axle from moving axially relative to the hub body due to vibration and impact during riding. This significantly improves the anti-loosening performance of the hub assembly, reduces wheel wobble, lowers maintenance frequency, and improves riding safety and reliability.

[0024] like Figure 3 As shown, the entire hub assembly is mounted on the mounting bracket 600 via the shaft 200, and the mounting bracket 600 is located between the retaining ring 300 and the fastener 400, thereby defining the position of the mounting bracket 600.

[0025] This application provides a hub assembly, including a hub body 100, a shaft 200, a retaining ring 300, and a fastener 400. Specifically, the hub body 100 has a first mounting hole 101, and a rotating support (not shown) is provided in the first mounting hole 101. The rotating support is interference-fitted into the first mounting hole 101. The shaft 200 is rotatably mounted in the first mounting hole 101 via the rotating support. The retaining ring 300 is sleeved on the shaft 200 and abuts against the rotating support. The fastener 400 is disposed on the shaft 200.

[0026] In this embodiment, the rotating support is a bearing, which can withstand radial force and a certain axial force. For example, the rotating support can be a deep groove ball bearing, etc. In practice, other bearings that meet the radial and axial load requirements can also be selected. The size and type of the specific bearing are not limited here. The rotating support is referred to as a bearing in the following description.

[0027] In this embodiment, the fastener 400 is a nut, specifically an anti-slip nut.

[0028] Please see Figure 1 As shown, in order to enable the hub body 100 to rotate relative to the axle 200, the axle 200 is rotatably mounted in the first mounting hole 101 via a bearing. In order to prevent the bearing from moving axially relative to the axle 200 due to bumps during bicycle riding, and to prevent the bicycle from shaking during riding due to axial movement of the bearing, a retaining ring 300 is also fitted on the axle 200 to block the bearing and prevent the bearing from moving axially.

[0029] Furthermore, in order to ensure that the bearing does not move axially, the outer ring of the bearing is connected to the inner wall of the first mounting hole 101 by an interference fit, so that the bearing is firmly connected to the inner wall of the first mounting hole 101. In addition, the inner ring of the bearing can also be connected to the outer peripheral surface of the shaft 200 by an interference fit, thereby preventing the bearing from moving axially relative to the hub body 100 and the shaft 200.

[0030] In this embodiment, the retaining ring 300 abuts against the inner ring of the bearing.

[0031] In this embodiment, the fastener 400 is screwed onto the shaft 200 to apply a pressing force to the mounting bracket 600 toward the bearing, thereby acting on the retaining ring 300 and providing the bearing with sufficient resistance, thus preventing axial movement of the bearing.

[0032] In this embodiment, the hub body 100 can be made of aluminum alloy, which can reduce its weight while ensuring that the hub body 100 has good strength, thereby making the vehicle faster when driving.

[0033] In some embodiments, the retaining ring 300 has a first anti-slip texture 310 on the end face opposite to the rotating support member.

[0034] Please see Figure 1 and Figure 2 As shown, in order to increase the friction between the retaining ring 300 and the side of the mounting bracket 600 and prevent the retaining ring 300 from rotating relative to the shaft 200 and causing wear due to friction with the bearing, a first anti-slip texture 310 is provided on the end face of the retaining ring 300 facing the mounting bracket 600. That is, a first anti-slip texture 310 is also provided on the end face of the retaining ring 300 away from the bearing, thereby increasing the friction between the retaining ring 300 and the mounting bracket 600.

[0035] In some embodiments, the shaft 200 is fitted with a spring washer 410, which is located on the side of the fastener 400 facing the rotating support.

[0036] like Figure 1 and Figure 2 As shown, in order to prevent the fastener 400 from loosening due to vibration during bicycle use, a spring washer 410 is provided on the side of the fastener 400 facing the bearing. When the spring washer 410 is compressed, it will give the fastener 400 a reverse force, which makes the fastener 400 fully abut against its connecting thread. That is, the threaded surface of the fastener 400 is fully abutted against the threaded surface of the shaft 200, making it difficult to rotate and reducing the risk of the fastener 400 loosening due to vibration.

[0037] In this embodiment, corresponding anti-slip textures can also be provided on the end face of the fastener 400 to increase the friction between the fastener 400 and the spring washer 410, thereby further reducing the risk of the fastener 400 becoming loose.

[0038] In some embodiments, an anti-slip pad 420 is also fitted on the shaft 200, and the anti-slip pad 420 is located on the side of the spring pad 410 facing the rotating support.

[0039] Please continue reading. Figure 1 and Figure 2 As shown, to further prevent the fastener 400 from rotating and loosening due to vibration, an anti-slip pad 420 is provided between the spring washer 410 and the mounting bracket 600. Under the force from the spring washer 410, the friction between the anti-slip pad 420 and the mounting bracket 600 is increased, and the anti-slip pad 420 and the spring washer 410 make surface contact, thereby further preventing the spring washer 410 and the fastener 400 from rotating.

[0040] In some embodiments, the anti-slip pad 420 is provided with a second anti-slip texture 421 on the side facing the rotating support.

[0041] like Figure 1 and Figure 2 As shown, by providing a second anti-slip texture 421 on the end face of the anti-slip pad 420 that contacts the mounting bracket 600, the friction between the second anti-slip texture 421 and the mounting bracket 600 is increased, thereby preventing the anti-slip pad 420, spring washer 410 and fastener 400 that abut against each other in sequence from becoming loose.

[0042] In this embodiment, the second anti-slip texture 421 and the first anti-slip texture 310 are rectangular or arc-shaped protrusions, and the thickness of the protrusions can be designed according to actual needs, which is not limited here.

[0043] In some embodiments, the hub body 100 includes a sleeve 110 and a convex ring 120. The sleeve 110 has a first mounting hole 101, and the convex ring 120 is disposed on both sides of the circumferential surface of the sleeve 110. The convex ring 120 is provided with a plurality of second mounting holes 121 distributed along the axis of the sleeve 110.

[0044] like Figure 1 As shown, the hub body 100 is composed of a sleeve 110 and protruding rings 120 located on both sides of the circumference of the sleeve 110. The sleeve 110 and the protruding rings 120 are integrally formed. The diameter of the protruding rings 120 is larger than the diameter of the sleeve 110, that is, the protruding rings 120 protrude from the outer circumference of the sleeve 110.

[0045] Furthermore, in order to enable the hub body 100 to be connected to the wheel body 500 via the spokes 510, a plurality of second mounting holes 121 are provided on the convex ring 120 at uniform intervals along its axis. The second mounting holes 121 are used for mounting and connecting the spokes 510.

[0046] In some embodiments, the shaft 200 includes an integrally formed smooth rod portion 210 and a threaded portion 220, and the fastener 400 is disposed on the threaded portion 220.

[0047] It should be noted that the smooth rod portion 210 has no threads on its outer circumferential surface, that is, the outer circumferential surface of the smooth rod portion 210 is a smooth surface, while the threaded portion 220 has threads on the outer circumferential surface of the rod.

[0048] In this embodiment, the retaining ring 300 is sleeved on the outer circumferential surface of the smooth rod portion 210, and the fastener 400 is installed on the threaded portion 220 by means of threaded connection. As the fastener 400 is screwed on the threaded portion 220, it gradually provides an axial abutment force to the spring washer 410 and the anti-slip washer 420. Under the reaction force of the spring washer 410, the fastener 400 is not easy to rotate and loosen under the action of vibration force, thus improving safety.

[0049] This embodiment also provides a wheel, which includes the hub assembly described above and the wheel body 500. The wheel body 500 is provided with spokes 510 and the wheel body 500 is connected to the hub body 100 through the spokes 510.

[0050] like Figure 2 As shown, in order to achieve the connection between the wheel body 500 and the hub body 100, multiple spokes 510 are provided between the wheel body 500 and the hub body 100. One end of the spoke 510 is provided on the second mounting hole 121 of the hub body 100, and the other end of the spoke 510 is provided on the inner ring of the wheel body 500. As the spokes 510 are evenly distributed around the circumference of the hub body 100, the connection and installation between the hub body 100 and the wheel 500 are completed.

[0051] This embodiment also provides a bicycle, which includes the wheels and mounting bracket 600 described above, with the wheels disposed on the mounting bracket 600.

[0052] For example, the bicycle can be a two-wheeled vehicle, a three-wheeled bicycle, or a four-wheeled bicycle, etc. The specific type of bicycle is not limited here. That is, as long as the vehicle body can use the wheels and hub assembly of this application, it is within the protection scope of this application.

[0053] The mounting bracket 600 includes a frame 610, the frame 610 having a third mounting hole 611, a sleeve 620 being disposed in the third mounting hole 611, and the sleeve 620 having a fourth mounting hole 621 extending through it along its axial direction.

[0054] Please see Figure 2 and Figure 3 As shown, in order to enable the mounting bracket 600 to adapt to shafts 200 of different diameters, the mounting bracket 600 is divided into two parts: the frame 610 and the sleeve 620. That is, the frame 610 and the sleeve 620 are connected separately. When it is necessary to use shafts 200 of different diameters, it is only necessary to replace the sleeve 620 with a different fourth mounting hole 621.

[0055] For example, the sleeve 620 can be fixedly installed in the third mounting hole 611 by welding, thereby completing the relative fixation between the frame 610 and the sleeve 620.
