Description

Technical Field

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

[0002] The wheel hub is a cylindrical metal part in the tire of a car that is used to support the tire with the axis as the center. In layman's terms, it is the part where the axle is installed in the center of the wheel. It is an important component that connects the brake drum (brake disc), wheel disc and half-axle. The wheel hubs on the market can be divided into steel wheel hubs and alloy wheel hubs according to the material. Due to the light weight and high manufacturing precision of aluminum alloy wheel hubs, they have small deformation and inertial resistance when rotating at high speed. Aluminum alloy wheel hubs have the metal characteristics of absorbing vibration and rebound force. After being processed by CNC machine tools, the dimensional accuracy, high roundness, small runout and good balance make the car run smoothly and comfortably. When the vehicle is running on a low-lying road or a road with a lot of gravel, the wheel hub needs to be protected to prevent gravel and other debris from affecting the wheel hub.

[0003] For example, the Chinese patent publication number CN217145517U discloses an aluminum alloy wheel hub, which relates to the field of wheel hubs and includes an outer ring and a fixed plate, a baffle plate is clamped on the outer ring, a shielding member is rotatably installed in the middle of the fixed plate, a torsion spring is fixed between the shielding member and the fixed plate, a plurality of hollow holes are provided on the baffle plate, the shielding member is matched with the hollow holes, a threaded hole is provided on the baffle plate, a fixing member is threadedly connected in the threaded hole, and a pull rope is connected between the bottom end of the fixing member and the shielding member. The utility model is an aluminum alloy wheel hub, by rotating the fixing member, the pull rope will gradually wrap around the fixing member, the pull rope will pull the shielding member to rotate until the shielding member completely overlaps the hollow hole, so that the shielding member blocks the hollow hole, thereby effectively preventing gravel and foreign matter from entering between the baffle plate and the fixed plate, and preventing foreign matter from contacting the brake disc, thereby ensuring the service life of the brake disc.

[0004] After using the aluminum alloy wheel hub, it was found that although the wheel hub can effectively prevent gravel and foreign objects from entering between the baffle and the fixed plate, when in use, it is pulled by a pull rope. When the vehicle is driving, the brake disc is hot and the temperature inside the wheel hub is high, which may affect the pull rope. In addition, the pull rope structure is not durable and has low practicality. Utility Model Content

[0005] The utility model aims to provide an aluminum alloy wheel hub to solve the problem that the pull rope structure is not durable.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum alloy wheel hub, comprising an outer ring, a fixing plate fixedly connected to the inside of the outer ring, a hollow hole opened on the surface of the fixing plate, a baffle plate provided on the inner side of the fixing plate, a rotating circle fixedly connected to the outer side of the baffle plate, teeth fixedly connected to the surface of the rotating circle, a bracket fixedly connected to the inner side of the fixing plate, a worm gear rotatably connected to the upper part of the bracket, a first gear rotatably connected to the lower part of the bracket, and a second gear fixedly connected to the side of the first gear.

[0007] Preferably, a rotating shaft is fixedly connected to the middle portion of the fixed plate, and the baffle is rotatably connected to the rotating shaft.

[0008] Preferably, a rotating rod is fixedly connected to the front side of the worm.

[0009] Preferably, a hexagonal mounting groove is provided on the front side of the rotating rod.

[0010] Preferably, the worm is meshed with the first gear.

[0011] Preferably, the teeth cooperate with the second gear.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model uses a hexagonal wrench to rotate the rotating rod, the worm rotates, the first gear rotates, the first gear causes the second gear to rotate, the teeth are moved, the rotating circle rotates, the baffle plate rotates, and the hollow hole is blocked. The baffle plate is used to block the hollow hole, which can prevent foreign objects such as gravel from entering the interior. On a flat road surface without foreign objects such as gravel, the rotating rod is rotated in the opposite direction so that the baffle plate no longer blocks the hollow hole. The air flow can cool the brake disc and the wheel hub, and the pull rope structure is eliminated, so that the structure is more durable and has a longer service life.
