Description

Technical Field

[0001] This utility model relates to the technical field of wheel hubs, specifically to a spliced ​​wheel hub with a long service life. Background Technology

[0002] The main function of the wheel hub is to be tightly integrated with the tire, forming a whole that supports the rotation of the entire wheel and affects the vehicle's performance. It not only bears the weight of the vehicle but also withstands various impacts and torques from the road surface during driving, thus having a significant impact on the vehicle's handling, stability, and safety.

[0003] A search revealed Chinese patent publication number CN220809010U, which discloses a wheel hub with a long service life, relating to the field of wheel hub technology. The invention includes a wheel hub body, an inner rim fixedly mounted on the inner surface of the body, an outer cover on the side of the inner rim, a water-absorbing pad fixedly connected to the side of the outer cover, ventilation holes on the surface of the outer cover, a handle fixedly mounted on the side of the outer cover, a locking rod fixedly mounted on the side of the outer cover, and a positioning hole on the side surface of the inner rim. Using the handle, the position of the outer cover can be easily moved to align the locking rod on the outer cover with the positioning hole on the surface of the inner rim, allowing the locking rod to be inserted into the positioning hole and rotated a certain angle along the annular groove to lock the outer cover onto the inner rim. This allows the water-absorbing pad to contact the connecting parts between the wheel hub and the drive shaft, thus keeping the connecting parts dry for a long time and preventing rust. When maintaining a wheel hub that has been in use for a long time, it also avoids the need for time to deal with rusted connecting parts.

[0004] However, while a car is in motion, it is inevitable that some sharp object on the bottom surface will pierce the inside of the tire, causing the tire to leak air or even burst. At this time, the downforce of the car body will be supported by the wheel rim at that position, and at the moment of the tire burst, the wheel rim will rub against the ground, causing the edge of the wheel rim to rub against the ground, thus posing a risk of damage to the wheel rim. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a spliced ​​wheel hub with a long service life. It solves the problem that when a car is in motion, a sharp object on the bottom surface may inevitably pierce the tire, causing air leakage or a tire blowout. In this case, the downforce of the vehicle body is supported by the wheel hub at that location, and at the moment of a tire blowout, the wheel hub will rub against the ground, causing the edge of the wheel hub to rub against the ground, thus posing a risk of damage to the wheel hub.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a spliced ​​wheel hub with a long service life, comprising a wheel hub, a first protective ring and a second protective ring, wherein the outer sidewall of the wheel hub is symmetrically provided with slots, the first protective ring and the second protective ring are respectively inserted into the slots, and the ends of the first protective ring and the second protective ring after installation extend to the outside of the wheel hub.

[0007] Preferably, a limiting block is fixedly installed on the right end of the first protective ring, and a limiting hole is provided inside the left end of the second protective ring. The limiting blocks are slidably connected inside the limiting holes, thereby enabling a tight connection between the first and second protective rings.

[0008] Preferably, the left end top surface of the second protective ring is provided with mounting holes, and the mounting holes are connected to the interior of the limiting holes. The interior of the limiting blocks is provided with threaded holes. The first protective ring and the second protective ring are connected to the interior of the threaded holes by bolts passing through the interior of the mounting holes. A sealing block is installed inside the mounting holes to make the connection between the first protective ring and the second protective ring more secure.

[0009] Preferably, the widths of the first and second protective rings are matched with the width of the slot, thereby preventing the first and second protective rings from wobbling after installation.

[0010] Preferably, the first protective ring and the second protective ring are located in the middle of the wheel hub, thereby preventing obstruction of the tire sidewall after installation and avoiding friction between the tire and the first and second protective rings during use.

[0011] This utility model provides a spliced, long-life wheel hub. It has the following beneficial effects:

[0012] This type of spliced ​​wheel hub with long service life, through the cooperation between the first and second protective rings, can easily make the first and second protective rings fit against the bottom surface in the event of a tire blowout, thus preventing the wheel hub from rubbing against the ground;

[0013] This type of spliced ​​wheel hub with long service life allows for easy replacement of the wheel hub by using the first and second protective rings, thus extending its service life. Attached Figure Description
