Description

Resonator wheel with improved fixing power

The present invention relates to a resonator wheel with improved fixing force, and more particularly, to a resonator wheel having a resonator mounted along the circumference of a rim, and improved fixing force of the resonator by using a band.

NVH (Noise, Vibration, Harshness) refers to the noise and vibration generated from parts constituting a vehicle, N stands for Noise, V stands for Vibration, and H stands for Harshness. NVH includes powertrain component noise generated from engine and transmission, road noise generated between tires and the ground during driving, and wind noise generated by wind. NVH is one of the most important consideration factors in the process of vehicle development, and many studies are being conducted to reduce it. In particular, development of tires and related parts is in progress to reduce road noise.

The tire of the vehicle is attached to the rim of the wheel and supports the vehicle body through the cushioning action of the air filled inside the tire and transmits the driving force of the vehicle body between the vehicle body and the ground. When a car is driving, constant friction occurs between the tire and the ground, and the tire generates a resonance sound due to the space where sound waves can resonate. The resonance sound is high in the frequency band of 200 ~ 300Hz, and it is transmitted to the inside and outside of the car, which not only causes inconvenience to drivers, passengers and outside pedestrians due to noise and vibration, but also reduces the riding comfort according to the continuous noise.

In order to solve this problem, conventionally, a method of reducing resonance noise generated in the inner space of a tire by mounting a resonator using a Helmholtz resonator principle on a rim was used.

Here, when the resonator forms a space like a jar, the air acts as a mass in the neck part, and the air in the inner space acts as a spring to cause resonance, and when resonating, the air in the neck part enters and exits heavily. It is a device that absorbs sound by converting it into thermal energy by friction with the tube wall.

As a conventional resonator, Korean Patent Application Laid-Open No. 10-2008-0038312 'A device and system for reducing tire and wheel noise' is disclosed. Thus, a technology is disclosed to act as a hollow chamber.

However, although this has a high sound absorption effect, it is easily removed from the tire due to deterioration of the durability of the fabric layer, so that the resonance sound cannot be effectively reduced.

The resonator body 21 has a resonator tube 210 for air to flow protruding from one side thereof, and forms a space for air to be contained therein, and a band coupling groove 211 may be formed in the center along the length.

Here, the resonance tube 210 may be provided in various lengths according to the user's request. For example, in the case of a resonator wheel 1 consisting of a plurality of resonators 20, the resonance tube 210 of each resonator 20 is formed in various lengths to easily absorb the frequency reaching the resonance tube 210. can

This is derived by the principle of the Helmholz resonator, and the resonant frequency generated in the resonator 21 is proportional to the cross-sectional area of the resonator tube 210, the diameter and length of the resonator tube 210, and the volume of the resonator body 21 Since it is inversely proportional to , it can be easily adjusted by changing each condition. Preferably, the resonance frequency can be changed by adjusting the length of the resonance tube 210 .

Specifically, the frequency of road noise generated between the tire and the ground appears in the range of about 30 to 60 Hz and 80 to 200 Hz, and a high band in the range of 200 to 300 Hz may also appear. By mounting the resonator 20 that generates the resonant frequency for the corresponding frequency on the rim 12, the rod noise can be effectively eliminated. Accordingly, the resonator 20 can cancel the vibration of a desired frequency band, thereby reducing the load noise.

In addition, the resonator body 21 may include a guide groove 212 to be temporarily assembled to the rim (12). The guide groove 212 is formed along the inner surface of the resonator body 21 , and may be formed at a position corresponding to the guide portion 40 of the rim 12 .

In addition, when the resonator 20 is configured as one, the connection bridge 22 may not be provided, and the resonator body 21 may be of a form that forms one length. However, it is preferable that the resonator body 21 is configured so that the inlet of the resonance tube 210 is not blocked.

When formed based on a plurality of resonators 20, the distance between the resonators 20 may be adjusted or the overall length of the resonators 20 may be adjusted by adjusting the length of the connection bridge 22.

In addition, the connection bridge 22 may guide the band 30 through the band coupling groove 211 . Here, the connection bridge 22 may be provided with a guide wall 220 erected on both sides to guide the band 30 .

The guide wall 220 has a width that matches or approximates the width of the band 30 so that the band 30 fits exactly, so that the band 30 is accurately surrounded along the length of the central part of the resonator 20 . It is preferable to guide and prevent side deviation so that the fixing force of the resonator 20 is always constant, but is not limited thereto.

At this time, the guide wall 220 may form a height equal to or greater than the height of the band 30 to facilitate the guide, but is not necessarily limited thereto. may be smaller.

When the guide wall 220 is equal to or greater than the height of the band 30 , as shown in FIG. 8 , the upper end of the guide wall 220 is formed to be bent in the coupling direction of the band 30 . A preventive piece 2200 may be provided.

The vertical departure prevention piece 2200 may close or compress a part or the entire upper portion of the band 30 to prevent upper separation, may be formed to maintain a folded state or may be formed to be folded and bent, and may be formed to be folded along the length It may be formed as a plural or provided at regular intervals along the length.

The rib 23 may be provided when formed based on a plurality of resonators 20, and when formed with one resonator 20, the resonator body 21 forms one length, so it may be unnecessary .

In addition, the resonator 20 of the present invention may be formed to be concave with a predetermined round value (R), that is, the surface in contact with the rim 12 as shown in FIG. 6 , that is, the rear surface. Here, the round value (R) of the rear surface of the resonator 20 may be about 0.5 ° to 2 °, and the rear surface of the resonator 20 is horizontal when pressing the front of the resonator 20 through the band 30 and Adhesion with the rim 12 is formed.

The band 30 of the present invention is mounted to surround the resonator 20 along the length of the band coupling groove 211, and may be bound to each other through both ends.

The guide part 40 of the present invention is formed on one surface of the rim 12 , and may be formed in a position facing the guide groove 212 on the lower surface of the resonator 20 . The guide part 40 may be inserted into and coupled to the guide groove 212 , and at this time, the coupling of the guide part 40 and the guide groove 212 causes the resonator 20 to not move before the band 30 is fastened. It can serve as a temporary fix to prevent it from happening.

In addition, it can serve to guide the position of the resonator 20 in the rim 12 by determining the position of the guide portion 40 and the guide groove 212 according to the user's request.

In addition, the guide part 40 may prevent vertical deviation by forming a width sufficient to be forced into the guide groove 212 . For example, when the guide part 40 has a width of 4 mm and the guide groove 212 has a width of 3.8 mm, the guide part 40 and the guide groove 212 are 0.1 mm on one side and 0.2 mm on both sides.
