이하, 첨부한 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 내측에 배치되는 라디에이터 안착용 플라스틱 케이스(13)와, 외측에 배치되는 차체 지지용 스틸 케이스(14)와, 상기 플라스틱 케이스(13) 및 스틸 케이스(14) 사이에 채워지는 고무체(15)를 일체형으로 조합시킨 구조로 이루어진 것을 특징으로 한다.The present invention relates to a plastic case 13 for seating a radiator disposed on the inside, a steel case 14 for supporting a vehicle body disposed on the outside, and a rubber body filled between the plastic case 13 and the steel case 14 ( It is characterized in that it is made of a structure in which 15) is combined integrally.

특히, 상기 플라스틱 케이스(13)의 벽체에는 둘레를 따라 가면서 일정한 간격으로 배치되는 다수의 절개홈(16)이 형성되어 있는 것을 특징으로 한다.In particular, the wall of the plastic case 13 is characterized in that a plurality of cut-out grooves 16 are formed along the circumference and arranged at regular intervals.

또한, 상기 플라스틱 케이스(13)는 고무체(15)에 의해 지지되면서 스틸 케이스(14)의 윗면 보다 다소 높게 위치되는 것을 특징으로 한다.In addition, the plastic case 13 is supported by the rubber body 15 and is positioned slightly higher than the upper surface of the steel case 14.

또한, 상기 스틸 케이스(13)의 벽체 둘레에는 소정의 두께로 완충용 보조 고무체(17)가 부착되는 것을 특징으로 한다.In addition, a shock absorbing auxiliary rubber body 17 is attached to a predetermined thickness around the wall of the steel case 13.

이를 좀더 상세히 설명하면 다음과 같다.This will be described in more detail as follows.

첨부한 도 2는 본 발명에 따른 방진고무의 단면구조를 보여주고 있다.2 shows the cross-sectional structure of the vibration-proof rubber according to the present invention.

본 발명의 방진고무(10)는 라디에이터의 안착을 위한 플라스틱 케이스(13)와, 차체측에 지지되기 위한 스틸 케이스(14)와, 상기 플라스틱 케이스(13)와 스틸 케이스(14)를 일체형으로 묶어주기 위해 그 사이에 채워지는 고무체(15)로 구성되어 있다.The anti-vibration rubber 10 of the present invention includes a plastic case 13 for seating a radiator, a steel case 14 for support on the vehicle body side, and the plastic case 13 and the steel case 14 in an integral form. It is composed of a rubber body (15) that is filled in between to give.

상기 플라스틱 케이스(13)와 스틸 케이스(14)는 서로 동심원을 유지하면서 각각 내측과 외측에 배치되고, 각 케이스간의 간격에는 소정의 형상으로 된 고무체(15)가 채워지게 됨에 따라 일체형의 방진고무(10)가 완성될 수 있게 된다.The plastic case 13 and the steel case 14 are disposed inside and outside, respectively, while maintaining concentric circles, and a rubber body 15 having a predetermined shape is filled in the gap between each case, so that an integral type of anti-vibration rubber (10) can be completed.

이때의 상기 플라스틱 케이스(13)의 벽체에는 둘레를 따라 가면서 일정한 간격으로 배치되는 다수의 절개홈(16)이 형성되어 있으며, 상기 절개홈(16)은 위아래로 길게 절개된 형태로 형성되는 길다란 홈으로 되어 있어서 그 안쪽으로 고무체(15)가 채워지게 되고, 이에 따라 플라스틱 케이스(13)와 고무체(15) 간의 높은 결합력을 기대할 수 있게 된다.At this time, the wall of the plastic case 13 has a plurality of incision grooves 16 arranged at regular intervals along the circumference, and the incision groove 16 is an elongated groove formed in an elongated shape cut up and down. The rubber body 15 is filled inside the rubber body 15, so that a high bonding force between the plastic case 13 and the rubber body 15 can be expected.

또한, 상기 스틸 케이스(13)의 벽체 외부 둘레에는 소정의 두께로 완충용 보조 고무체(17)가 부착되어 있으며, 이러한 보조 고무체(17)에 의해 차체(12)와의 접촉성을 좋게 유지할 수 있게 된다.In addition, an auxiliary rubber body 17 for buffering is attached to the outer circumference of the wall of the steel case 13 with a predetermined thickness, and the contact property with the vehicle body 12 can be maintained by this auxiliary rubber body 17. There will be.

즉, 스틸 케이스(14)와 차체(12) 간의 접촉성을 좋게 하여 소음발생을 최대한 억제할 수 있고, 또 진동 흡수효과를 향상시킬 수 있게 된다.That is, by improving the contact property between the steel case 14 and the vehicle body 12, noise generation can be suppressed as much as possible, and the vibration absorption effect can be improved.

따라서, 이와 같이 구성된 본 발명의 방진고무(10)는 외측에 있는 스틸 케이스(14)를 이용하여 차체(12)에 받쳐지는 구조로 지지되고, 내측에 있는 플라스틱 케이스(13)의 홀(11)을 통해 라디에이터 보스가 삽입 안착되므로서, 방진고무(10) 통한 라디에이터의 방진구조가 이루어질 수 있게 된다.Therefore, the anti-vibration rubber 10 of the present invention configured as described above is supported in a structure supported by the vehicle body 12 using the steel case 14 on the outside, and the hole 11 of the plastic case 13 on the inside Through the radiator boss is inserted and seated, the vibration-proof structure of the radiator through the anti-vibration rubber 10 can be achieved.

이렇게 본 발명의 방진고무를 채용하여 라디에이터의 하부를 받쳐주는 방진구조에서는 차체측과의 접촉 진동에 따른 반복적인 집중하중을 보조 고무체를 통해 스틸 케이스가 받아내게 되므로, 방진고무의 전체적인 내구력을 높일 수 있게 되며, 또한 플라스틱 케이스 및 고무체의 연계적인 구성이나 고무체의 형태에서 발휘되는 고유 스프링 특성에 따른 탄력적인 완충작용에 의해 진동 흡수성능을 높일 수 있게 되는 것이다.In this way, in the vibration-proof structure that supports the lower part of the radiator by adopting the vibration-proof rubber of the present invention, the steel case receives the repetitive concentrated load due to the contact vibration with the vehicle body side through the auxiliary rubber body, thereby increasing the overall durability of the vibration-proof rubber In addition, it is possible to increase the vibration absorption performance by the elastic buffering action according to the inherent spring characteristics exerted in the form of the rubber body or the connected configuration of the plastic case and the rubber body.
