Description

차량의 소음저감용 휠{Wheel for noise reduction of vehicle}Wheel for noise reduction of vehicle

본 발명은 차량용 휠에 관한 것으로, 특히 주행 중 노면에서 전달되는 소음진동을 저감할 수 있는 차량의 소음 저감용 휠에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wheel for a vehicle, and more particularly, to a wheel for reducing noise of a vehicle capable of reducing noise vibrations transmitted from a road surface while driving.

주지된 바와 같이 차량용 휠은 내부로 주입된 압축공기에 의해 지지력을 갖는 타이어와 결합되어 타이어의 지지대 기능을 하는 것으로, 타이어와 더불어 차량의 접지력 향상에 따른 주행 안정성과 경량화를 통한 주행성능 및 조향성을 좋게 해주기 위한 용도로 사용되고 있다.As is well known, the wheel for a vehicle functions as a support for the tire by being combined with a tire having a bearing force by compressed air injected into the vehicle. The driving performance and steering performance through weight reduction along with the tire are improved. It is used for the purpose of making it good.

또한, 최근 친환경 추세에 맞추어 소비자들은 안락성능과 연비성능을 요구하면서 외형적인 면에서 볼 때 차량에 고급스러운 분위기를 주거나, 또는 스포티한 감각을 주기도 하는 등 차량의 전체적인 분위기를 좌우하는 휠을 요구하고 있는 실정이다.In addition, in line with the recent eco-friendly trend, consumers demand wheels that determine the overall atmosphere of the vehicle, such as giving a luxury atmosphere to the vehicle or giving a sporty sensation while demanding comfort performance and fuel economy performance. There is a situation.

한편, 차량은 대형화 되면서 타이어는 로우 시리즈(Low series)화 되고 중량은 연비향상을 위해서 점차적으로 감소하는 추세이다.On the other hand, as vehicles become larger, tires become low series and the weight gradually decreases to improve fuel efficiency.

이에 따라 주행중인 타이어와 노면에서 소음진동을 저감하기 위해서 타이어 구조 및 고무를 변경하거나 개량시킨 구조가 다양하게 제안되었으나, 타이어에서 소음진동을 개선하는데 한계가 있었다.Accordingly, in order to reduce noise vibrations on running tires and road surfaces, various tire structures and structures with modified or improved rubbers have been proposed, but there are limitations in improving noise vibrations in tires.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 발명된 것으로, 차량 주행 중 노면에서 전달되는 소음진동을 저감할 수 있는 차량의 소음 저감용 휠을 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described conventional problems, and an object thereof is to provide a wheel for reducing noise of a vehicle capable of reducing noise vibrations transmitted from a road surface while driving a vehicle.

The rubber cylindrical body is inserted and seated, the length (L) of the rubber cylindrical body is formed slightly smaller than the length (ℓ) of the inner cylindrical hole and its width (W) is formed smaller than the width (d) of the inner cylindrical hole It is structured.

이러한 본 발명에 따른 차량의 소음 저감용 휠은 주행 중 타이어가 회전할 때 상기 고무 원통체가 스포크 부재의 내부 원통구멍 내에서 상하좌우로 움직여서 공기 흐름을 조정하는 댐퍼 역할을 수행함에 따라 가진이 커지거나 작아질 때 힘을 분산 및 완화시키어 노면에서 전달되는 소음진동을 저감시키는 기능을 갖게 된다.The wheel for reducing noise of the vehicle according to the present invention has an increase in excitation as the rubber cylinder moves up, down, left and right in the inner cylindrical hole of the spoke member to adjust the air flow when the tire rotates while driving. When it is small, it has the function of dispersing and mitigating the force to reduce the noise vibration transmitted from the road surface.
