Description

Technical Field

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

[0002] The automobile wheel hub is the intermediate component that fixes the tire and connects the tire to the axle. It is an important part of automobile parts. It is responsible for carrying the weight of the vehicle, transmitting power, supporting the tire, etc., and as a rotating moving part, the wheel hub must meet the technical conditions of light weight, fatigue resistance, and dynamic balance under the premise of having a certain rigidity. With the increasing urgency of energy conservation and emission reduction, automobile lightweighting has become a new direction for the development of the automobile industry. Lightweight design is to optimize the design of the automobile structure to reduce the weight of the automobile under the premise of ensuring that the automobile meets the basic rigidity and strength. The existing authorized patent (Announcement No.: CN214564335U) is a lightweight wheel hub. Although the lightweight wheel hub reduces the weight of the wheel hub, it reduces the energy consumption of the automobile, improves product performance, and reduces production costs.

[0003] However, the bolt holes on the lightweight hub mounting plate lack a sealing and waterproof structure. When the hub is connected to the axle through the mounting plate, the nut is exposed and easily susceptible to moisture and water ingress. Currently, a hub cover is used and installed on the hub through a snap-on structure to protect the nut from rust and waterproofing. The hub cover with a snap-on structure has a simple structure and is easy to disassemble and assemble, but there is a certain probability that the snap-on structure may be pried open and damaged when it is removed. Therefore, in view of the current situation, it needs to be improved. Utility Model Content
