Rim structure

Technical Field

The utility model relates to a wheel hub's for the vehicle technical field, concretely relates to rim structure.

Background

It is known that air column resonance generated in a tire air chamber formed between a tire and a rim of a wheel hub becomes a factor of load noise of an automobile. The air column resonance is a resonance phenomenon that random excitation input transmitted from a road surface to a tire tread during running vibrates air in a tire air chamber and occurs in the vicinity of a resonance frequency of the tire air chamber. Due to this resonance phenomenon, air column resonance noise is generated in the tire air chamber. The air column resonance noise is transmitted to the vehicle body via the suspension, and is sensed as load noise in the vehicle. As a hub for reducing such load noise, there have been proposed various structures provided with a helmholtz resonator having a sub air chamber communicating with a tire air chamber via a communication hole. However, when the hub rotates, a shock excitation input is generated to the tire when the tire tread is in contact with the ground. The prior solutions generally provide sound attenuation by adding a helmholtz resonator to the outer circumferential surface of the hub. But this causes the following problems: the Helmholtz resonator is additionally fixed on the outer circumferential surface of the rim, and can be separated from the hub and fall into a tire cavity along with the rotation and vibration of the hub and the heating deformation of the hub during the running process of a vehicle; once drop to the tire intracavity, the effect of amortization has just been lost to the helmholtz resonator, and the helmholtz resonator is scurried along with the rotation of wheel in the tire moreover, not only can improve the noise of tire on the contrary, still can harm the potential safety hazard of bad tire even.
