본 발명은 댐퍼풀리의 흡음재 결합구조에 관한 것으로서, 특히 흡음재를 댐퍼풀리에 결합하는 작업이 매우 용이해지고, 흡음재에 별도의 끼움판이 밀착 형성됨에 따라 흡음재의 소음 감쇄효율이 더욱 향상되도록 한 댐퍼풀리의 흡음재 결합구조에 관한 것이다.The present invention relates to a sound absorbing material coupling structure of the damper pulley, and in particular, the operation of coupling the sound absorbing material to the damper pulley becomes very easy, and as the separate fitting plate is formed in close contact with the sound absorbing material, the damping efficiency of the sound absorbing material is further improved. It relates to a sound absorbing material coupling structure.

일반적으로 댐퍼풀리는 크랭크샤프트의 앞쪽에 결합되어 회전하면서 보기류벨트에 의해 연결된 워터펌프풀리, 알터네이터 풀리 등을 구동시켜 보기류 및 밸브트레인계를 구동시키는 역할을 하면서 엔진의 크랭크 샤프트에서 발생한 비틀림진동을 저감하는 기능을 갖는다.In general, the damper pulley is coupled to the front of the crankshaft and rotates to drive the water pump pulley and alternator pulley connected by the bogie belt to drive the bogie and the valve train system. It has a function to reduce.

그리고, 댐퍼풀리의 전면에는 흡음재가 결합되어 엔진으로부터 방사되는 소음을 흡수하여 감쇄시키는 기능을 갖는다.The sound absorbing material is coupled to the front surface of the damper pulley to absorb and attenuate noise radiated from the engine.

크랭크샤프트(1)의 앞쪽에 댐퍼풀리(2)가 축결합되어 있고, 상기 댐퍼풀리(2)의 전면으로 일정두께의 흡음재(3)가 다수의 볼트(4)로서 결합되어 있다.A damper pulley 2 is axially coupled to the front of the crankshaft 1, and a sound absorbing material 3 of constant thickness is coupled as a plurality of bolts 4 to the front surface of the damper pulley 2.

그러나, 종래에는 흡음재(3)가 다수의 볼트(4)에 의해 댐퍼풀리(2)에 결합되는 구조이기 때문에 제품 조립시 다수의 볼트(4)를 조여야만 하는 등 그 조립과정이 길어지면서 제품의 생산성이 하락하게되고, 다수의 부품으로 이루어지기 때문에 제품의 생산원가가 상승하게되며, 품질관리가 어려워지는 문제점이 발생하고 있었다.However, in the related art, since the sound absorbing material 3 is coupled to the damper pulley 2 by a plurality of bolts 4, the assembly process becomes longer as the assembly process becomes longer, for example, a plurality of bolts 4 must be tightened. Productivity is lowered, the production cost of the product is increased because it consists of a large number of parts, the quality control was difficult.

따라서, 상기 문제점을 해결하기 위한 본 발명은 댐퍼풀리의 전면측 내주면상에 환형의 그루브를 요입 형성하고, 상기 댐퍼풀리의 전면으로 결합되는 흡음재의 일측에 그루브에 억지끼움되는 탄성재로 형성된 끼움판을 형성하므로서, 흡음재를 댐퍼풀리에 결합하는 작업이 매우 용이해지고, 흡음재에 별도의 끼움판이 밀착 형성됨에 따라 흡음재의 소음 감쇄효율이 더욱 향상되도록 한 댐퍼풀리의 흡음재 결합구조를 제공함을 목적으로 한다.Therefore, the present invention for solving the above problems is formed of an annular groove on the inner peripheral surface of the front side of the damper pulley, the insertion plate formed of an elastic material that is pressed into the groove on one side of the sound absorbing material coupled to the front of the damper pulley By forming a, it is very easy to combine the sound absorbing material to the damper pulley, and as the separate fitting plate is formed in close contact with the sound absorbing material to provide a sound absorbing material coupling structure of the damper pulley to further improve the noise attenuation efficiency of the sound absorbing material.

이하, 첨부된 도면 도 1 내지 도 3 을 참조하여 본 발명의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 1 to 3.

본 발명의 설명에 있어서 종래와 동일한 구성요소에 대해서는 동일부호 표기하여 중복설명을 피하기로 한다.In the description of the present invention, the same components as in the prior art will be denoted by the same reference numerals to avoid redundant description.

도면부호 10 은 크랭크 샤프트(1)의 앞쪽에 축 결합되는 댐퍼풀리를 나타낸다.Reference numeral 10 denotes a damper pulley axially coupled to the front of the crankshaft 1.

본 발명에서는 흡음재(12)의 결합을 위해 도 1 과 도 2 에 도시된 바와같이 상기 댐퍼풀리(10)의 전면측 내주면상에 환형으로 그루브(11)를 요입 형성한다.In the present invention, the groove 11 is recessed in an annular shape on the inner circumferential surface of the front side of the damper pulley 10 as shown in FIGS. 1 and 2 for coupling the sound absorbing material 12.

그리고, 상기 댐퍼풀리(10)에 결합되는 흡음재(12)의 일측에 끼움판(13)을 부착 결합하는데, And, the attachment plate 13 is attached to one side of the sound absorbing material 12 coupled to the damper pulley 10,

이때, 상기 끼움판(13)은 그 직경이 흡음재(12)의 직경보다 약간 크도록 설정하여 상기 러버플레이트(13)의 외주면이 상기 그루브(11)에 억지끼움될 수 있도록 하며, 소정의 탄성을 갖는 탄성재로서 형성하는 것이 바람직하다.At this time, the fitting plate 13 is set so that the diameter is slightly larger than the diameter of the sound absorbing material 12 so that the outer peripheral surface of the rubber plate 13 can be fitted to the groove 11, and the predetermined elasticity It is preferable to form as an elastic material which has.

상기 끼움판(13)은 탄성을 갖는 러버플레이트로서 형성하여도 무방하다.The fitting plate 13 may be formed as a rubber plate having elasticity.

상기 끼움판(13)의 외주면에는 도 2 에 도시된 바와같이 모따기부(14)를 형성하여 끼움판(13)을 그루브(11)에 억지끼움할때 보다 용이하게 삽입될 수 있도록 하는 것이 바람직하다.On the outer circumferential surface of the fitting plate 13, it is preferable to form the chamfer 14 as shown in FIG. 2 so that the fitting plate 13 can be easily inserted when the fitting plate 13 is inserted into the groove 11. .

이와같이 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

댐퍼풀리(10)의 전면에 흡음재(12)를 결합하고자 할때 본 발명에서는 상기 흡음재(12)의 일측에 형성되어있는 끼움판(13)을 도 2 에 도시된 바와같이 댐퍼풀리(10)의 전면측 내주면상에 환형으로 요입 형성되어 있는 그루브(11)에 억지끼움하는 것으로 간편하게 결합시킬 수 있다.When the sound absorbing material 12 is coupled to the front surface of the damper pulley 10, in the present invention, the fitting plate 13 formed on one side of the sound absorbing material 12 is shown in FIG. 2 of the damper pulley 10. It can be combined easily by forcibly fitting into the groove 11 which is formed in the annular recess in the front side inner peripheral surface.

상기 끼움판(13)을 그루브(11)에 결합할때에는 끼움판(13)의 외주면상에 형성된 모따기부(14)에 의해 일정한 힘으로 끼움판(13)을 눌러주는 것으로 간편하게 조립할 수 있게되는 것이다.When the fitting plate 13 is coupled to the groove 11, the fitting plate 13 can be easily assembled by pressing the fitting plate 13 with a constant force by the chamfer 14 formed on the outer circumferential surface of the fitting plate 13. .

그리고, 상기 흡음재(12)의 일측에 끼움판(13)이 부착 결합되므로 결과적으로 흡음재(12)의 두께가 두꺼워지는 효과가 발생하면서 엔진으로부터 방사되는 연소음 및 크랭크 샤프트 타격음 등이 효과적으로 감쇄되어 차량의 정숙성이 향상되 는 부가적인 효과를 기대할 수 있다.In addition, since the fitting plate 13 is attached to one side of the sound absorbing material 12, as a result, the thickness of the sound absorbing material 12 is thickened, and the combustion sound emitted from the engine and the crankshaft hitting sound are effectively attenuated. Additional effects of improved quietness can be expected.

또한, 종래와같이 흡음재를 다수의 볼트로서 결합하는 것이 아니라 댐퍼풀리(10)에 형성된 그루브(11)에 끼워 조립하는 것이기 때문에 다수의 볼트가 결합되지 않음에 따라 차량의 중량을 줄여줄 수 있고, 부품수의 감소로 인해 제품의 생산성 향상 및 원가절감의 효과가 발생하는 것이다.In addition, it is possible to reduce the weight of the vehicle as the plurality of bolts are not coupled because the sound absorbing material is not assembled as a plurality of bolts, but rather assembled into the grooves 11 formed in the damper pulley 10. Due to the reduction of the number of parts, the productivity improvement and cost reduction effect occur.

그리고, 상기 적용된 끼움판(13)은 러버플레이트와 같이 소정의 탄성을 가지는 탄성재로서 형성가능한 것임을 밝혀둔다.And, it is noted that the applied fitting plate 13 can be formed as an elastic material having a predetermined elasticity, such as a rubber plate.

이상에서 설명한 바와같이 본 발명은 댐퍼풀리의 전면측 내주면상에 환형의 그루브를 요입 형성하고, 상기 댐퍼풀리의 전면으로 결합되는 흡음재의 일측에 그루브에 억지끼움되는 끼움판을 형성하므로서, 흡음재를 댐퍼풀리에 결합하는 작업이 매우 용이해지고, 흡음재에 별도의 끼움판이 밀착 형성됨에 따라 흡음재의 소음 감쇄효율이 더욱 향상되도록 한 댐퍼풀리의 흡음재 결합구조를 제공하는 효과를 기대할 수 있다.As described above, the present invention forms an annular groove on the inner circumferential surface of the damper pulley, and forms a fitting plate that is pressed into the groove on one side of the sound absorbing material coupled to the front surface of the damper pulley, thereby damping the sound absorbing material. The operation of coupling to the pulley is very easy, and the separate fitting plate is formed in close contact with the sound absorbing material can be expected to provide an effect of providing a sound absorbing material coupling structure of the damper pulley to further improve the noise attenuation efficiency of the sound absorbing material.
