Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a low-noise automotive wheel hub. Background Technology

[0002] A wheel rim is a cylindrical metal component mounted on an axle, supporting the tire's inner contour. It is also called a wheel rim, steel rim, wheel hub, or tire rim. Wheel rims come in many varieties depending on their diameter, width, molding method, and materials. Car wheel rims are an indispensable part of automobiles, playing a crucial role. With technological advancements, more and more manufacturers have innovated wheel rims, leading to rapid development in their production. Car wheel rims generate significant noise when rotating at high speeds, and since wheel rims themselves do not have noise reduction or sound absorption capabilities, the resulting noise level during vehicle operation is considerable. Therefore, a type of car wheel rim that can effectively reduce noise is needed. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a low-noise automotive wheel hub, which has the following beneficial effects:

[0015] 1. By setting up slots, inserts, wind-damping noise reduction plates, circular grooves, and circular blocks, when using low-noise car wheel hubs, the wind-damping noise reduction plates are installed on the wheel spokes through the inserts, and the circular blocks form a complete disc to cover the wheel hub and spokes, effectively reducing the impact of air on the wheel hub and spokes during car driving, thereby achieving a noise reduction effect. It is highly practical.

[0016] Second, by setting up a first sound-absorbing panel, a front retaining strip, a rear retaining strip, a second sound-absorbing panel, and an arc-shaped protrusion, when the low-noise car wheel hub rotates rapidly with the car's movement, the second sound-absorbing panel, in conjunction with the arc-shaped protrusion, effectively breaks through the air, reduces wind resistance, and effectively reduces noise generation. At the same time, the first and second sound-absorbing panels work together to effectively absorb and eliminate the generated noise, thereby reducing noise. It is highly practical. If the first and second sound-absorbing panels are damaged, they can be quickly disassembled and repaired using the front and rear retaining strips, offering high flexibility.

[0017] Third, by setting up silent bearings, the low-noise car wheel hub is connected to the car half shaft when the car rotates with the car, thereby effectively reducing the noise generated by the bearing itself when the wheel hub rotates quickly, which is highly practical.
