Description

Technical Field

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

[0002] The wheel hub is the rotating part of the wheel core connected to the inner profile of the tire through a column, that is, the metal component mounted on the axle in the center of the tire. It is used to support the weight of the vehicle body and transfer the weight to the ground, while transmitting the rotation of the axle to the external tire to enable the car to move.

[0003] As driving conditions become increasingly complex, there are often facilities such as speed bumps on the road. Cars will inevitably bump during driving, which will produce impact force on the wheel hub. Under long-term impact force, deformation or even spoke breakage may occur, causing safety hazards. Therefore, we propose a lightweight aluminum alloy wheel hub. Utility Model Content

[0012] The utility model embeds side reinforcement rings on the left and right sides of the rim to improve the impact resistance of the rim side, and embeds an inner wall reinforcement ring on the inner side of the rim to improve the impact resistance of the rim.

[0013] The structural setting of the front and rear spoke frames can further improve the integrity of the hub structure. If one spoke frame has a problem during driving, the other spoke frame can also play a supporting role. The vehicle can still drive normally without any safety hazards, greatly reducing driving risks.

[0014] Through the structural setting of the auxiliary buffer component, the impact force can be absorbed to a certain extent, the degree of impact on the entire wheel hub can be reduced, and the driving stability of the vehicle can be improved.
