Technical Field

[0001] The utility model belongs to the field of automotive parts, relates to a wheel hub, and particularly relates to a wheel hub with a drainage and lubrication structure. Background Technique

[0002] A wheel hub is a cylindrical metal part that supports the tire inside the tire profile and is centered on the shaft. It is also called a rim, a steel rim, a wheel, or a tire bell. There are many types of wheel hubs according to different diameters, widths, forming methods, and materials.

[0003] For example, a new type of wheel hub with the publication number CN213291873U includes a wheel center, a rim, and multiple spokes evenly distributed along the circumference of the wheel hub. Both ends of the spokes are respectively fixedly connected to the wheel center and the rim. Adjacent spokes, the wheel center, and the rim enclose a window. The spoke includes a first inclined section and a second inclined section. The first inclined section extends outward from the wheel center to the outside of the wheel hub at a certain angle. The second inclined section connects to the end of the first inclined section and extends inward to the rim at a certain angle. An inner rim boss flush with the outer rim is provided at the middle position of the inner side of the rim corresponding to the window.

[0004] However, when the above wheel hub is in rainy weather or when driving through a waterlogged area, it is extremely easy for rainwater to enter the axle core hole in the center of the automotive wheel hub, causing water accumulation, and resulting in water accumulation problems at the contact part between the axle and the axle core hole. Content of the Utility Model

[0005] The utility model provides a wheel hub with a drainage and lubrication structure, which has a good drainage structure, thereby effectively avoiding the occurrence of water accumulation.

[0006] The technical solution adopted by the utility model to solve the above technical problems is: a wheel hub with a drainage and lubrication structure, including a wheel hub body. An axle hole and a number of threaded holes arranged annularly around the axle hole are opened on the wheel hub body. A drainage groove is provided between each threaded hole and the axle hole. The diameters at both ends of the drainage groove are larger than the diameter at the center point of the drainage groove. An elastic sheet is fixedly connected to the end of the drainage groove close to the threaded hole. There is a gap between the elastic sheet and the inner wall of the drainage groove. When a solid is stuck in the drainage groove, the elastic sheet deforms, the gap becomes smaller, and the diameter of the end of the drainage groove close to the threaded hole becomes larger.

[0007] A further preferred technical solution of the utility model is: a number of installation grooves are opened at the end of the drainage groove close to the threaded hole. The elastic sheet is fixedly connected in the installation groove, and the gap is located between the elastic sheet and the inner wall of the installation groove.

[0008] A further preferred technical solution of the utility model is: the elastic sheet is an arc-shaped sheet.

[0009] A further preferred technical solution of the utility model is: the gap is a closed space.

[0010] A further preferred technical solution of the present utility model is that the elastic sheet is a rubber sheet.

[0011] A further preferred technical solution of the present utility model is that two installation grooves are provided, and the two installation grooves are symmetrically arranged with the longitudinal central axis of the drainage groove as the symmetry axis.

[0012] A further preferred technical solution of the present utility model is that arc-shaped surfaces are provided on both side walls of the drainage groove.

[0013] A further preferred technical solution of the present utility model is that the depth of the drainage groove deepens from the end close to the threaded hole to the end close to the shaft hole.

[0014] Compared with the prior art, the present utility model includes a hub body, a shaft hole is provided on the hub body, and a plurality of threaded holes are annularly arranged around the shaft hole. A drainage groove is provided between each threaded hole and the shaft hole. The diameters of both ends of the drainage groove are larger than the diameter at the center point of the drainage groove. An elastic sheet is fixedly connected to the end of the drainage groove close to the threaded hole, and there is a gap between the elastic sheet and the inner wall of the drainage groove. When a solid is stuck in the drainage groove, the elastic sheet deforms due to the extrusion of the solid. At this time, the gap becomes smaller and the diameter of the end of the drainage groove close to the threaded hole becomes larger. At this time, under the push of the water flow, the sundries are discharged through the shaft hole. This design enables the width of the drainage groove to be adjusted according to the actual situation, thereby further improving the drainage effect of the drainage groove and effectively avoiding the blockage of the drainage groove.

[0022] The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present utility model.

[0023] It should be noted that: Similar reference numerals denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0024] Figure 1 and Figure 2 As shown, a hub with a drainage and lubrication structure includes a hub body 1. A shaft hole 3 and a number of threaded holes 2 arranged annularly around the shaft hole 3 are provided on the hub body 1. During installation, the axle for installing the hub is passed through the shaft hole 3 to install the hub on the vehicle. Thereafter, a protective cover is covered on the surface of the hub body 1, and a bolt is screwed into the threaded hole 2 to fix the protective cover on the hub body 1.

[0025] Figure 1 and Figure 2 As shown, a drainage groove 4 is provided between each threaded hole 2 and the shaft hole 3. The diameters of both ends of the drainage groove 4 are larger than the diameter at the center point of the drainage groove 4. Arc-shaped surfaces are provided on both side walls of the drainage groove 4. Therefore, during drainage, it is convenient for water flow and debris in the water flow to enter the drainage groove 4 better. At the same time, due to the larger diameters at both ends, it can effectively prevent debris from getting stuck at the mouth of the drainage groove 4 and affecting the discharge of water flow.

[0026] Figure 1 and Figure 2 As shown, the depth of the drainage groove 4 deepens from the end close to the threaded hole 2 to the end close to the shaft hole 3. This design further prevents debris from blocking in the drainage groove 4, thereby improving the drainage effect of the drainage groove 4.

[0027] Figures 3 - 5 As shown, an elastic sheet 5 is fixedly connected to the end of the drainage groove 4 close to the threaded hole 2. There is a gap 6 between the elastic sheet 5 and the inner wall of the drainage groove 4. Therefore, when a solid is stuck in the drainage groove 4, the elastic sheet 5 deforms due to the extrusion of the solid. At this time, the gap 6 becomes smaller and the diameter of the end of the drainage groove 4 close to the threaded hole 2 becomes larger. At this time, under the push of the water flow, the debris is discharged through the shaft hole 3. This design enables the width of the drainage groove 4 to be adjusted according to the actual situation, thereby further improving the drainage effect of the drainage groove 4 and effectively preventing the drainage groove 4 from being blocked.

[0028] Figures 3 - 5 As shown, several mounting grooves 7 are provided at one end of the drain groove 4 close to the threaded hole 2. There are two mounting grooves 7, and the two mounting grooves 7 are symmetrically arranged with the longitudinal central axis of the drain groove 4 as the symmetry axis. The elastic piece 5 is fixedly connected in the mounting groove 7, and the gap 6 is located between the elastic piece 5 and the inner wall of the mounting groove 7. By providing the mounting groove 7, the elastic piece 5 has enough space to deform, and the drain groove 4 can be widened after the elastic piece 5 deforms.

[0029] Figures 3 - 5 As shown, the elastic piece 5 is an arc-shaped piece, so that water flow and sundries can flow along the arc of the elastic piece 5, avoiding blockage of sundries and further improving the anti-blocking effect.

[0030] Figures 3 - 5 As shown, the gap 6 is a closed space, effectively preventing water flow from entering the gap 6.

[0031] Figures 3 - 5 As shown, the elastic piece 5 is a rubber piece. The rubber piece has good elastic deformation ability and good recovery effect. When the mass of the sundries is small, squeezing the rubber piece can also make it deform, so that the sundries can pass through, further improving the drainage effect of the drain groove 4.

[0032] The above introduces a hub with a drainage lubrication structure provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and its core idea. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
