Description
본 고안은 중장비의 내부 소음원으로부터 소음이 외부로 방사되는 통로인 각 장치들 사이의 틈새를 차폐하기 위한 차음띠에 관한 것이다.The present invention relates to a sound insulation strip for shielding a gap between devices, which is a passage through which noise is radiated outward from an internal noise source of heavy equipment.
일반적으로, 중장비는 저속이나 정지시 작업을 수행하게 되므로 상대적으로 큰 냉각성능이 요구되며, 이로인해 큰 성능을 갖는 냉각팬이 장착되므로 내부 소음원으로부터 전달되는 소음도 부가적으로 더 크게 되어 그 소음의 외부전달을 차폐하여야 한다.In general, heavy equipment requires relatively large cooling performance because the work is performed at a low speed or at a standstill, and as a result, a cooling fan having a large performance is installed. Transmission must be shielded.
종래에는 중장비의 내부소음원으로부터 전달되는 소음을 차단하기 위해, 소음의 주 통과요소인 그릴의 개방부또는 각 장치들사이의 틈새를 구성하는 구성요소를 일체로 제작하였다. 이와같이, 중장비의 내부소음원으로부터 소음이 외부로 전달될 수 있는 모든 가능한 개구부를 장치와 일체로 접합함으로써, 아예 소음이 외부로 전달되지 못하도록 차단하였다.Conventionally, in order to block the noise transmitted from the internal noise source of the heavy equipment, the component of the opening of the grill which is the main passage element of the noise or the components forming the gap between the devices were integrally manufactured. In this way, all possible openings through which the noise can be transmitted from the internal noise source of the heavy equipment to the outside are integrally bonded to the device, thereby preventing the noise from being transmitted to the outside at all.
하지만, 종래의 이러한 경우는 개구부를 통해 전파되는 소음을 차폐하기 위해 개구부를 구성하는 각 구성요소를 일일이 접합하여야 하므로 너무 많은 제작비가 들게 되는 문제점이 있었다. 이에, 본 고안은 이러한 문제점을 해결하기 위한 것으로, 그 목적은 중장비의 내부소음원으로부터 소음이 전달될 수 있는 개구부를 접합가능한 얇은 재질을 이용하여 막음으로써, 소음전달을 방지하는 차음띠를 제공함에 있다.However, in this case of the related art, in order to shield the noise propagated through the opening, each component constituting the opening must be bonded one by one, which causes a problem in that too much manufacturing cost is required. Accordingly, the present invention is to solve this problem, the object of the present invention is to provide a sound insulation band to prevent the transmission of noise by blocking the opening that can transmit noise from the internal noise source of heavy equipment using a thin material that can be bonded. .

위와같은 목적을 달성하기 위한 본 고안의 특징은 중장비의 내부소음원으로부터 외부로 전달되는 소음을 차폐하기 위한 장치에 있어서, 내부소음원이 구성된 내부공간으로부터 외부를 향해 개방된 틈새를 밀폐하여 소음의 전달을 차폐하는 것을 특징으로 하는 차음띠에 있다.A feature of the present invention for achieving the above object is a device for shielding the noise transmitted to the outside from the internal noise source of the heavy equipment, sealing the gap opened toward the outside from the internal space consisting of the internal noise source to transmit the noise It is in the sound insulation strip characterized by shielding.
이하에서 본 고안의 구성 및 작용을 설명하기 위해 첨부된 도면을 참조하여 설명한다. 도1은 소음이 전달되는 틈새에 장착된 본 고안에 따른 차음띠를 도시한 측면도이다. 본 도에서는 중장비의 내부소음원으로부터 발생되는 소음이 엔진룸(10)과 하부프레임(20)이 이루는 틈새를 통해 외부로 전달되는 경우를 일예로 들어 도시하고 있다. 일반적으로, 엔진룸(10) 및 이와 결합되는 하부프레임(20)에서 소음원으로 작용하게 되는 것은 엔진, 변속기 및 토오크변환기 등이 있다. 엔진을 포함한 이러한 소음원들은 엔진룸(10)과 하부프레임(20)사이의 틈새(30)을 통해 외부로 전달된다. 따라서, 소음을 차폐하기 위해서는 틈새(30)를 막아주어야 하며, 이를 위해 틈새(30)중 외부쪽으로 향한 개방부에 주로 고무로 제작된 차음띠(40)가 접합된다. 이렇게 틈새(30)에 접합되는 차음띠(40)는 여러 형상으로 구성될 수 있고, 그 접합형태도 여러가지이다. 이러한 형상 및 접합형태에 대해서는 도2 및 도4를 참조하여 설명한다. 도2내지 도4는 본 고안에 따른 차음띠의 여러 형상 및 접합형태를 보여주기 위한 도면으로, 도2(a),도3(a) 및 도4(a)는 정면도이고, 도2(b),도3(b) 및 도4(b)는 그 측면도이다. 이중, 도2의 차음띠(40)는 그 단면형상이 반구형이며, 도3의 차음띠(50)는 이러한 반구형상에 돌기(52)가 구성되어 있다. 이중, 도3의 돌기(52)는 결합되는 틈새(도1의 30)에 삽입되어 차음띠(50)를 더욱 밀착시키는 역할을 하는 것으로, 틈새의 크기에 따라 그 폭이 달리 구성된다. 게다가, 도4의 차음띠(60)는 양끝단에 턱(62)을 갖는 형상으로 구성되어 있다. 이 턱(62)은 대략 평판형상으로 이루어지며, 차음띠(60)가 틈새(도1의 30)에 접합될 때에 틈새를 구성하는 엔진룸(도1의10) 및 하부프레임(도1의20)의 외부면에 맞닿게 되는 부분이다. 게다가, 이 턱(62)에 나사못 등과 같은 체결재(64)로 체결함으로써, 차음띠(60)를 엔진룸 및 하부프레임의 외부면에 더욱 밀착하여 체결할 수 있게 되는 것이다. 물론, 앞서 설명한 차음띠의 여러 형상외에도 틈새의 구조에 따라 다른 형상으로 또 달리 구성할 수도 있다. 하여튼, 이와같은 차음띠는 중장비의 내부소음원으로부터 발생하는 소음을 차음띠를 이용하여 틈새를 막음으로써, 소음을 차폐할수 있다. 또한, 이러한 차음띠를 접합하는 형태에 있어서도, 소위 끈끈이라 불리우는 접착재료를 사용하여 접합할 수도 있다.Hereinafter, with reference to the accompanying drawings to explain the configuration and operation of the present invention. 1 is a side view showing a sound insulation strip according to the present invention mounted in a gap through which noise is transmitted. In this figure, for example, the noise generated from the internal noise source of the heavy equipment is transmitted to the outside through the gap formed by the engine room 10 and the lower frame 20 as an example. In general, the engine room 10 and the lower frame 20 coupled to the engine source, the transmission and the torque converter is to act as a noise source. These noise sources, including the engine, are transmitted to the outside through the gap 30 between the engine room 10 and the lower frame 20. Therefore, in order to shield the noise, the gap 30 must be blocked, and for this purpose, the sound insulation strip 40 mainly made of rubber is joined to the opening toward the outside of the gap 30. The sound insulation strip 40 bonded to the gap 30 may be configured in various shapes, and the joining form is also various. Such a shape and a joining form will be described with reference to FIGS. 2 and 4. 2 to 4 is a view for showing the various shapes and bonding form of the sound insulation strip according to the present invention, Figure 2 (a), Figure 3 (a) and Figure 4 (a) is a front view, Figure 2 (b) 3 (b) and 4 (b) are side views thereof. Of these, the sound insulation strip 40 of Fig. 2 has a hemispherical cross-sectional shape, and the sound insulation strip 50 of Fig. 3 has protrusions 52 formed on such a hemispherical shape. Of these, the projection 52 of Figure 3 is inserted into the gap (30 of Figure 1) to be coupled to serve to close the sound insulation strip 50, the width is configured differently depending on the size of the gap. In addition, the sound insulation strip 60 of FIG. 4 is comprised in the shape which has the jaw 62 in the both ends. The jaw 62 is formed in a substantially flat plate shape, and the engine compartment (10 in FIG. 1) and the lower frame (20 in FIG. 1) that constitute the gap when the sound insulation strip 60 is joined to the gap (30 in FIG. 1). ) Is the part that comes into contact with the outer surface of the In addition, by fastening the jaw 62 with a fastener 64 such as a screw, the sound insulation strip 60 can be fastened to the outer surface of the engine room and the lower frame in close contact. Of course, in addition to the various shapes of the sound insulation strip described above, it may be configured differently in another shape according to the structure of the gap. In any case, the sound insulation strip can shield the noise by using the sound insulation strip to prevent noise generated from the internal noise source of the heavy equipment. Moreover, also in the aspect which joins such a sound insulation strip, it can also bond using what is called an adhesive material called a string.
상술한 바와같이, 본 고안에 따른 차음띠는 중장비의 내부소음원으로부터 외부로 개방된 개방부 및 틈새를 밀봉함으로써, 이를 통해 외부로 전달되는 소음을 간단히 차폐할수 있는 장점이 있다.As described above, the sound insulation strip according to the present invention has the advantage of simply shielding the noise transmitted to the outside through sealing the opening and the gap opened to the outside from the internal noise source of the heavy equipment.
