Description

Technical Field

[0001] This invention relates to the field of automotive wheel hub technology, specifically to a wheel hub unit with a low-friction sealing component and a rapid assembly method. Background Technology

[0002] The existing car wheel hub is the part at the center of the wheel where the axle is installed, which is what people commonly call the wheel rim or steel rim. During the production of existing wheel hubs, in order to reduce the weight of the wheel hub, the middle part is mostly hollowed out, which reduces the force on the car during driving. In addition, the wheel hub itself is relatively light and easy for operators to install.

[0003] A search revealed a lubrication-friendly automotive wheel hub disclosed in patent number CN218171901U. The hub includes a wheel hub and an outer ring. Several spoke assemblies are arranged in a circular array between the outer ring and the hub. Each spoke assembly includes a spoke body and a sealing cap. This invention utilizes a sliding arc block within an arc groove in the wheel hub. During driving, the arc block, through rotational force, seals the arc groove, allowing lubricating oil to lubricate the hub. When the vehicle stops, the arc block slides to the left, opening the arc groove. Lubricating oil then flows from oil chamber one to oil chamber two and back to the arc groove. This achieves both lubrication of the wheel hub and conversion of the lubricating oil within the arc groove, thus providing heat dissipation.

[0004] According to the aforementioned patent, the wheel hub has hollowed-out ends to reduce its weight. However, this design allows a lot of dust to enter during use, making it easier for dust to get into the car's connecting bearings, thus affecting its service life. Furthermore, the diameter of the wheel hub cannot be adjusted when installing tires, making installation and removal quite cumbersome. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wheel hub unit with a low-friction sealing component and a rapid assembly method, solving the problems of poor wheel hub dust prevention and cumbersome tire installation.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a wheel hub unit with low-friction sealing components and a quick assembly method, comprising a wheel hub body, two sets of wheel hub sealing components for sealing and dust prevention on both sides of the wheel hub body, a closing component on the outside of the sealing and dust prevention wheel hub sealing components, and two sets of tire quick-installation components for quick tire installation on both sides of the wheel hub body.

[0007] The wheel hub sealing assembly includes a fixing ring fixedly disposed at one end of the wheel hub body. A sealing cover plate is provided at one end of the wheel hub body. Multiple limiting arc-shaped grooves are opened at one end of the fixing ring. A guide post is fixedly disposed in the middle of the limiting arc-shaped groove. Two guide grooves are symmetrically opened at both ends of the limiting arc-shaped groove. Two loop-shaped unlocking grooves are symmetrically opened at both ends of the limiting arc-shaped groove. The loop-shaped unlocking groove and the guide groove on the same side are interconnected.

[0008] Preferably, a sliding plate is slidably provided in the middle of the limiting arc groove, a limiting spring is fixedly provided at the upper end of the sliding plate, the other end of the limiting spring is fixedly connected to the upper end of the limiting arc groove, and the two guide posts slide in the middle of the sliding plate.

[0009] Preferably, a vertical extension block is fixedly provided at one end of the sliding plate, a vertical limiting groove is provided at one end of the limiting arc groove, one end of the vertical extension block slides in the middle of the vertical limiting groove, and a first extending barb plate is fixedly provided at the lower end of the sliding plate, with a first tilt angle provided at the end of the first extending barb plate near the guide groove.

[0010] Preferably, the lower end of the sealing cover is provided with a plurality of vertical extension plates, one end of the vertical extension plate is fixedly provided with a second extension barb plate, the end of the second extension barb plate near the U-shaped unlocking groove is provided with a second tilt angle, and the middle part of the second extension barb plate is fixedly provided with a follow guide block.

[0011] Preferably, the closing assembly includes a sealing cavity formed in the middle of the sealing cover plate, a central rotating plate rotatably provided in the middle of the sealing cavity, a plurality of limiting circular holes formed in the middle of the central rotating plate, an extension stop pin slidably provided in the middle of the limiting circular holes, a limiting piece fixedly provided at one end of the extension stop pin, an extension spring fixedly provided at one end of the limiting piece, the other end of the extension spring fixedly connected to one end of the limiting circular hole, and a plurality of circular grooves fixedly provided at one end of the sealing cover plate, the circular grooves and the limiting circular holes being arranged in equal numbers.

[0012] Preferably, the tire quick-installation assembly includes two outer shielding plates fixedly disposed at both ends of the wheel hub body. Two drive rings are symmetrically disposed at both ends of the wheel hub body via threaded connections. Two adjusting arc-shaped grooves are symmetrically opened at one end of each outer shielding plate. Multiple arc-shaped abutment blocks are fixedly disposed on the outer side of each drive ring. Multiple fixing sleeves are symmetrically fixedly disposed at both ends of the wheel hub body. A driven sliding block is slidably disposed in the middle of each fixing sleeve. An anti-detachment plate is fixedly disposed at one end of each driven sliding block. An arc-shaped contact block is fixedly disposed at the other end of each driven sliding block. Two connecting adjustment blocks are symmetrically fixedly disposed at one end of each drive ring.

[0013] A method for rapid assembly of a wheel hub unit with a low-friction sealing assembly, specifically including the following steps:

[0014] Step 1: Seal both sides of the conventional wheel hub body with the wheel hub sealing assembly to prevent excessive dust from entering during use. The wheel hub sealing assembly can be quickly installed on one end of the wheel hub body through the closing assembly.

[0017] Beneficial effects

[0018] This invention provides a wheel hub unit with a low-friction sealing assembly and a rapid assembly method. Compared with the prior art, it has the following advantages:

[0019] (1) The wheel hub sealing assembly can seal both ends of the wheel hub to prevent a lot of dust from entering the connection between the wheel hub and the vehicle when the vehicle is in motion, thereby reducing the dust entry rate. The limit spring in the wheel hub sealing assembly can quickly install and remove the sealing cover, which is convenient for subsequent maintenance and replacement of the wheel hub and will not hinder the operation of the wheel hub. The setting of multiple limit arc grooves ensures the stability of the sealing cover during installation and prevents it from falling off.

[0020] (2) The extension bar in the closure assembly can extend and retract, making it easy to remove the sealing cover. The extension bar can also block the operation hole on the surface of the sealing cover, so that the surface of the sealing cover is set on the same plane when in use, and its surface is smooth and beautiful.

[0021] (3) By extending outwards simultaneously through multiple arc-shaped contact blocks in the tire quick-installation assembly, the tire on the outside of the wheel hub can be lifted up, and the tire can be removed quickly, greatly improving the tire removal efficiency. The operation is simple; the tire can be lifted up simply by moving the connecting adjustment block. Attached Figure Description

[0031] This invention provides two technical solutions:

[0032] Example 1

[0039] Figure 1-4The second embodiment is shown. The main difference from the first embodiment is that the tire quick-install assembly 4 includes two outer shielding plates 401 fixedly disposed at both ends of the wheel hub body 1. Two drive rings 403 are symmetrically disposed at both ends of the wheel hub body 1 by threaded connection.

Two connecting adjusting blocks 409 are symmetrically fixedly disposed at one end of the drive rings 403.

[0040] This embodiment also discloses a method for rapid assembly of a wheel hub with a low-friction sealing component, specifically including the following steps:

[0041] Step 1: The wheel hub body 1 is sealed on both sides by the wheel hub sealing assembly 2 to prevent too much dust from entering during use. The wheel hub sealing assembly 2 can be quickly installed on one end of the wheel hub body 1 by the closing assembly 3.

[0042] Step 2: The tire quick-installation assembly 4 allows for quick removal and installation of the outer tire through its abutting configuration, which also ensures safe operation during use.

[0043] In this embodiment of the invention, the characteristic is that the closing component 3 in step 1 can make the wheel hub sealing component 2 have no protrusions or grooves on its surface, thus ensuring its aesthetics.

[0044] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0045] In use, the operator presses the extension stop in the closing assembly, which causes the extension stop to drive the limiting plate to compress the extension spring, thereby rotating the sealing baffle. This rotation causes the vertical extension plate to move, which in turn causes the second extension barb plate to move. The second tilt angle presses against the first tilt angle, causing the first extension barb plate to move, and the first and second barb extension plates to interlock. When unlocking is required, the upper sealing plate separates the first and second barb extension plates. The sliding plate moves upward through the limiting spring and is limited to the left and right by the vertical limiting groove and the sliding plate to prevent rotation. The accompanying guide block slides in the middle of the guide groove to limit the position of the second barb extension plate. The second barb extension plate is unlocked through the loop unlocking groove.

[0046] Rotating the connecting adjustment block in the quick-mount tire assembly drives the drive ring to rotate, which in turn drives the arc-shaped abutment block to rotate, causing the arc-shaped abutment block to extend outward, thus lifting the tire.
