Description

Technical Field

[0001] The utility model relates to the technical field of wheel hubs, in particular to a brushed aluminum alloy wheel hub. Background Art

[0002] The wheel hub is the part of a vehicle that mounts the wheel. Typically made of metal, it is the core component of the wheel, carrying the vehicle's weight and connected to the axle via bearings. The hub secures the wheel, allowing it to rotate smoothly. It typically consists of a hollow, disc-shaped structure with space for the tire. The design and manufacture of the wheel hub must consider factors such as strength, rigidity, weight, and durability to ensure safety and stability during driving. The exterior design of the wheel hub is also an important part of a vehicle's aesthetics, and different models and brands have their own unique wheel hub designs.

[0003] Most existing wheel hubs are hollow hubs composed of multiple spokes supporting the rim. When a vehicle travels on a bumpy road with a lot of gravel, the extrusion force during the rotation of the wheel hub will cause the gravel to pass through the hollows between the support columns and hit the components inside the wheel hub, causing damage to the brake disc or other components installed inside the wheel hub. At the same time, when the vehicle travels on muddy roads, mud splashes onto the brake disc, which will reduce braking performance and pose a certain safety hazard. Therefore, we propose a brushed aluminum alloy wheel hub to solve the above problems. Utility Model Content

The front isolation cover 4 and the back isolation cover 5 can be made of but not limited to acrylic material. The protection of the brake pads by the front isolation cover 4 and the back isolation cover 5 effectively prevents gravel from passing through the hollows between the spokes 3 and hitting the parts inside the wheel hub, thereby reducing damage to the brake disc or other components and helping to increase the service life of the brake disc and other parts. At the same time, when the vehicle is driving on a muddy road, mud is avoided from splashing onto the brake disc, thereby ensuring the braking performance of the car and reducing safety hazards caused by car driving.

[0041] A mounting ring 14 is fixedly provided on the inner side of the rim 1, and the mounting ring 14 is symmetrically arranged on the inner side of the rim 1, and the mounting plate 2 and the spoke 3 are both located between the mounting ring 14, and a clamp base ring 6 is fixedly installed on one side of the mounting ring 14 by screws, and a clamp limiting ring 7 is fixedly installed on one side of the clamp base ring 6, and a limiting ring groove 17 is provided on one side of the clamp limiting ring 7, and a clamp linkage ring 8 is rotatably connected inside the limiting ring groove 17. By embedding the clamp linkage ring 8 into the inside of the limiting ring groove 17, the clamp linkage ring 8 is rotatably connected to the inner side of the clamp limiting ring 7. When assembling the wheel hub, after the clamp linkage ring 8 is placed in the inner side of the limiting ring groove 17, the clamp limiting ring 7 is fixedly installed on one side of the clamp base ring 6 by screws, and one side of the clamp base ring 6 is rotated It is connected with a hoop resisting catch 9, and a linkage notch 21 is provided at the upper end of the hoop resisting catch 9. The hoop resisting catch 9 is arranged between the hoop base ring 6 and the hoop linkage ring 8. A linkage column 20 is fixedly provided on the side of the hoop linkage ring 8 close to the hoop resisting catch 9, and the linkage columns 20 are evenly distributed on one side of the hoop linkage ring 8. The linkage column 20 is slidably connected to the inner side of the linkage notch 21 opened at the upper end of the hoop resisting catch 9. When the hoop linkage ring 8 is rotated, the hoop linkage ring 8 drives the linkage column 20 fixed on one side thereof to move, and the linkage column 20 squeezes the side wall of the linkage notch 21, so that the annularly distributed hoop resisting catch 9 rotates synchronously. When the hoop resisting catch 9 no longer resists the front isolation cover 4 and the back isolation cover 5 arranged between the hoop resisting catch 9 and the mounting ring 14, Remove the front isolation cover 4 and the back isolation cover 5 for replacement.

[0042] An inner protective ring 11 and an outer protective ring 12 are attached to the edges of both sides of the front isolation cover 4 and the back isolation cover 5, wherein the inner protective ring 11 is attached to one side of the mounting ring 14, and a solid ring 13 is attached to one side of the outer protective ring 12, and the side of the solid ring 13 away from the outer protective ring 12 is in contact with the side of the clamping clamp 9, and the back isolation cover 5 and the front isolation cover 4 are both arranged between the inner protective ring 11 and the outer protective ring 12, and the inner protective ring 11 and the outer protective ring 12 can be made of, but not limited to, rubber material. The protective assembly composed of the inner protective ring 11, the outer protective ring 12 and the solid ring 13 can avoid the back The vibration wear between the isolation cover 5 and the mounting ring 14 and the hoop resisting catch 9 is beneficial to improving the service life of the front isolation cover 4 and the back isolation cover 5. When installing or replacing the front isolation cover 4 and the back isolation cover 5, it is only necessary to rotate the hoop linkage ring 8. The hoop linkage ring 8 squeezes the side wall of the linkage notch 21 through the linkage column 20 fixedly arranged on one side thereof, so that the hoop resisting catch 9 with a linkage notch 21 at one end rotates between the hoop base ring 6 and the hoop linkage ring 8, thereby making the hoop resisting catch 9 no longer resist the front isolation cover 4 and the back isolation cover 5. At this time, the front isolation cover 4 and the back isolation cover 5 can be taken out. The isolation cover 5, that is, the front isolation cover 4 and the back isolation cover 5 are separated from the rim 1. When the front isolation cover 4 or the back isolation cover 5 needs to be replaced, the front isolation cover 4 or the back isolation cover 5 with the inner protective ring 11, the outer protective ring 12 and the solid ring 13 fixed on the edge is placed on one side of the mounting ring 14, and the clamp linkage ring 8 is loosened. Under the action of the restoring force of the S-shaped leaf spring 10, the S-shaped leaf spring 10 pushes the clamp linkage ring 8 to rotate through the third limiting protrusion 19, thereby making the clamp resisting claw 9 return to its original position, that is, the second limiting protrusion 18 abuts against one side of the first limiting protrusion 16, and the clamp resisting claw 9 is restored to its original position. The grab 9 abuts against one side of the solid ring 13 to fix the front isolation cover 4 or the back isolation cover 5 on the rim 1. By setting a clamp mechanism composed of a clamp base ring 6, a clamp limiting ring 7, a clamp linkage ring 8 and a clamp resisting grab 9, it is not only convenient to replace the front isolation cover 4 and the back isolation cover 5, but also by setting the clamp mechanism to fix the front isolation cover 4 and the back isolation cover 5, there is no need to open screw fixing holes on the front isolation cover 4 and the back isolation cover 5, which ensures the integrity of the front isolation cover 4 and the back isolation cover 5 and is beneficial to improving the service life of the front isolation cover 4 and the back isolation cover 5.
