摘要

The present invention relates to a sound absorbing function central separator, and more particularly, the whole shape is composed of a "⊥" shape and a wall portion 12 formed perpendicular to the bottom portion 11 and the bottom portion 11, A pair of through holes 121 is formed at left and right sides of both sides of the wall part 12, and a plurality of fixing holes 122 are formed at upper and lower sides of both sides of the wall part 12, and an insertion groove 123 is formed at an upper part thereof. A communication hole 21 is formed to be inserted into and fixed in the through hole 121 of the central separator 10 and the central separator 10 to communicate with each other, while the outer circumferential surface of the communication hole 21 has a protrusion 22. The communication body 20 formed of the FRP material and the fastening groove 31 is formed on the inner side so as to fit into the protrusion 22 of the communication body 20, and the sound absorbing material 30 having a plurality of sliding grooves 32 formed on the outer circumferential surface thereof. And a streamlined body portion 41 and side portions 42 formed above and below the body portion 41, and fitted into the sliding grooves 32 of the sound absorbing material 30. A plurality of flange portions 421 to be formed are formed inside the body portion 41, and a plurality of sound absorbing holes 412 are formed on the outer circumferential surface of the body portion 41, and bolt holes 421 are formed on the side portion 42. The side cover 40 of the steel material and the fitting portion 51 to be fitted to the insertion groove 123 of the central separator 10 is formed at the bottom, while the wing portion 52 is formed to the left and right of the fitting portion 51 The structure including the upper cover 50 is characterized in that to efficiently reduce the noise of the vehicle passing.; Vehicle noise, median, sound absorber, top cover, side cover
