Description

Technical Field

[0001] This utility model relates to the field of automotive wheel hub technology, specifically to a superhydrophobic self-cleaning automotive wheel hub. Background Technology

[0002] The wheel hub is the rotating part of the wheel core connected to the inner profile of the tire by a column. The main structure of the wheel hub includes the rim, spokes, and mounting flange. The rim supports and positions the tire. The inner circumferential wall of the rim is usually a sloping structure to improve its resistance to deformation.

[0003] Wheel hubs are prone to accumulating dirt during use, especially in rainy or muddy environments. The inner walls of the rim and spokes easily become stained with grime, which is difficult to clean due to its location on the inside. This grime, if left for a long time, can corrode the rim and spokes. In addition, the slope of the inner circumference of the rim is relatively small, making it easy for water, such as rainwater and other water bodies, to remain for extended periods. If this water is not drained in time, it will not only accelerate the corrosion of the wheel hub but also affect driving safety. For example, when the rim rotates in rain or snow, its poor water-repellent properties can easily wet the tires, leading to slippage.

[0004] Therefore, this utility model provides a superhydrophobic self-cleaning automotive wheel hub. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a superhydrophobic self-cleaning car wheel hub to solve the problems mentioned in the background technology. This utility model has the advantages of better self-cleaning and hydrophobic effects, which greatly extends the service life of the wheel rim. Moreover, it has a simple structure, low cost and easy maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a superhydrophobic self-cleaning automotive wheel hub, comprising a hub body, the hub body including a rim, spokes, and a mounting flange, wherein a coaxial positioning ring is fixedly connected to the inner side of the mounting flange via a support arm, a rotating ring is fitted on the positioning ring, a cleaning ring is fixedly connected to the outer peripheral wall of the rotating ring via an arm, and a brush is provided on the outer peripheral wall of the cleaning ring, the brush being opposite to the inner wall of the rim, and a strip brush is provided on the side of the support arm opposite to the spokes.

[0007] Furthermore, the positioning ring is rotatably connected to a bearing and a rotating ring.

[0008] Furthermore, the number of the support arms is at least three, and they are distributed around the mounting flange at equal intervals.

[0009] Furthermore, the plate brush and strip brush are detachably connected to the cleaning ring and the support arm, respectively.

[0010] Furthermore, the positioning ring includes a positioning block and a brush bristle fixedly disposed on one side of the positioning block, and the inner peripheral wall of the cleaning ring is provided with a window that engages with the positioning block.

[0011] Furthermore, a second window is provided through one side of the arm, and the brush includes a strip and two bristles fixedly disposed on one side of the strip, with the strip and the second window engaging in a snap-fit ​​connection.

[0012] Furthermore, the inner circumferential wall of the rim is fixedly provided with circumferentially evenly distributed abutment protrusions.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, a positioning ring, a rotating ring, an arm, a cleaning ring, a plate brush, and a strip brush are provided. By rotatably connecting the rotating ring and the mounting flange, a speed difference exists between the rim and the cleaning ring when the rim rotates. This speed difference allows the plate brush and the strip brush to clean the inner circumferential wall of the rim and the inner side wall of the spokes, respectively. At the same time, the plate brush can quickly drain water from the rim, thus providing hydrophobic and self-cleaning functions. Moreover, the structure is simple and the manufacturing cost is low.

[0015] In this invention, windows one and two are respectively opened on the cleaning ring and the arm. By setting the plate brush and strip brush to be connected to windows one and two in a snap-fit ​​structure, the plate brush and strip brush are more convenient to install and remove, thus having the advantage of more convenient maintenance in the later stage.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a superhydrophobic self-cleaning automotive wheel hub, including a wheel hub body 1, which includes a rim 11, spokes 12, and a mounting flange 13. A coaxial positioning ring 2 is fixedly connected to the inner side of the mounting flange 13 via a support arm 131. The positioning ring 2 provides clearance for the installation of the automotive drive shaft. A rotating ring 3 is fitted onto the positioning ring 2. Preferably, the positioning ring 2 is rotatably connected to the rotating ring 3 via a bearing 7. During installation, the inner ring of the bearing 7 is positioned by machining a shoulder and a retaining ring groove on the positioning ring 2, and then the outer ring of the bearing 7 is limited by machining a retaining ring groove in the rotating ring 3. A cleaning ring 4 is fixedly connected to the outer peripheral wall of the rotating ring 3 via an arm 31. A brush 5 is provided on the outer peripheral wall of the cleaning ring 4. The brush 5 is opposite to the inner wall of the rim 11. When the cleaning ring 4 rotates relative to the rim 11, the brush 5 cleans the inner peripheral wall of the rim 11 and also accelerates water drainage. A strip brush 6 is provided on the side of the support arm 131 opposite to the spoke 12. When the cleaning ring 4 rotates relative to the rim 11, the strip brush 6 cleans the inner wall of the spoke 12.

[0022] In this embodiment, the plate brush 5 and the strip brush 6 are detachably connected to the cleaning ring 4 and the support arm 131, respectively. This arrangement facilitates the maintenance and replacement of the plate brush 5 and the strip brush 6 in the future.

[0023] Specifically, the positioning ring 2 includes a positioning block 51 and a brush bristle 52 fixedly disposed on one side of the positioning block 51. The brush bristle 52 is made of a high-temperature resistant material (such as palm fan blades). The inner peripheral wall of the cleaning ring 4 has a window 41 that engages with the positioning block 51. During manufacturing, the positioning block 51 is made of rubber, and an annular groove is opened on the outer periphery of the positioning block 51. The positioning block 51 engages with the window 41 through the annular groove. When it is necessary to disassemble the brush 5, it is only necessary to use a tool to peel the positioning block 51 off the window 41. During installation, the positioning block 51 is manually pressed into the window 41.

[0024] Furthermore, a second window 311 is provided through one side of the arm 31. The strip brush 6 includes a strip 61 and bristles 62 fixedly disposed on one side of the strip 61. The strip 61 and the second window 311 are engaged. During manufacturing, the strip 61 is also made of rubber. Slots that cooperate with the second window 311 are opened on both sides of the strip 61. The method of assembling and disassembling the strip 61 is the same as the method of installing the positioning block 51 mentioned above. The material of the second bristle 62 can be the same as the material of the first bristle 52.

[0025] In this embodiment, the inner circumferential wall of the rim 11 is fixedly provided with circumferentially evenly distributed baffles 111. The baffles 111 can increase the resistance when they come into contact with the bristles 52. This arrangement allows the rim 11 to drive the cleaning ring 4 to rotate when it rotates. When the rim 11 stops rotating, the cleaning ring 4 will continue to rotate under the action of inertial force, which has the functions of delayed cleaning of the rim 11 and spokes 12 and water repellency.

[0026] In this embodiment, the number of support arms 131 is at least three and they are distributed around the mounting flange 13 at equal intervals. This arrangement can improve the strength of the support for the positioning ring 2.

[0027] Working principle: When a car is driving in rain or snow, rainwater and mud will enter the inner side of the rim 11, and the mud and water will remain inside the rim 11 and the inner side of the spokes 12. The rotational angular velocity of the cleaning ring 4 is lower than that of the rim 11. At this time, the bristle brush 5 and the strip brush 6 brush the inner circumferential wall of the rim 11 and the inner side of the spokes 12 respectively, thereby avoiding dirt residue and accelerating drainage. During this process, the cleaning ring 4 will also rotate passively, and its rotational speed will be increased by the push of the baffle 111. Therefore, when the rim 11 stops rotating, the cleaning ring 4 will rotate for a delayed period of time. At this time, the bristles 52 and 62 on the bristle brush 5 and the strip brush 6 can delay cleaning the inner circumferential wall of the rim 11 and the inner side of the spokes 12, avoiding dirt residue on the wheel hub.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
