즉, 소음흡수부재(300)는 천연 고무재 또는 폴리에스테르 일래스토머(PE) 또는 실리콘 또는 폴리우레탄(PU) 등과 같은 탄성 재질로 형성되어 솔레노이드밸브(320)의 개폐 작동시 발생되는 작동소음이 감소되도록 충격을 흡수하는 댐핑부(312)가 슬리브(221a)를 지지하게 된다.That is, the noise absorbing member 300 is made of a natural rubber material or an elastic material such as polyester elastomer (PE) or silicone or polyurethane (PU) or the like, so that the operating noise generated when the solenoid valve 320 is opened and closed The damping portion 312 that absorbs the impact absorbs the sleeve 221a.

이어서, 슬리브(221a)에는 솔레노이드밸브(320)의 개폐 작동시 발생되는 작동소음을 효율성 있게 흡수하도록 평탄부(221d)가 형성되며, 댐핑부(312)가 평탄부(221d)에 압착되어 슬리브(221a)를 지지함으로써, 댐핑부(312)가 슬리브(221a)의 충격에너지를 보다 더 효율성 있게 흡수하게 된다.The flat portion 221d is formed in the sleeve 221a to efficiently absorb the operating noise generated when the solenoid valve 320 is opened and closed and the damping portion 312 is pressed against the flat portion 221d, 221a, the damping portion 312 absorbs the impact energy of the sleeve 221a more efficiently.

그리고, 지지부(310)의 일측에는 고정돌기(350)가 형성되고, ECU 하우징(311)에는 고정돌기(350)가 끼워져 고정되도록 체결홀(211c)이 형성된다.A fixing protrusion 350 is formed on one side of the support portion 310 and a coupling hole 211c is formed in the ECU housing 311 so that the fixing protrusion 350 is inserted and fixed.

체결홀(211c)에 끼워지는 고정돌기(350)는, 지지부(310)로부터 체결홀(211c)의 직경보다 작게 형성되는 연결부(330)와, 연결부(330)로부터 체결홀(211c)의 직경보다 크게 형성되되 체결홀(211c)을 관통하여 ECU 하우징(211)에 지지되는 걸림부(320)를 포함한다.The fixing protrusion 350 fitted in the fixing hole 211c has a connecting part 330 formed to be smaller than the diameter of the fixing hole 211c from the supporting part 310 and a connecting part 330 formed so as to be smaller than the diameter of the fixing hole 211c from the connecting part 330. [ And a latching part 320 which is formed to be large and is supported by the ECU housing 211 through the fastening hole 211c.

즉, 고정돌기(350)는 지지부(310)의 일측에 연결부(330)로 연결된 걸림부(320)가 형성되며, 체결홀(211c)을 관통하여 걸림턱(326)에 의하여 ECU 하우징(211)의 평판부(211b)에 고정된다.That is, the fixing protrusion 350 is formed with a latching part 320 connected to one side of the support part 310 by the connecting part 330. The latching protrusion 350 passes through the coupling hole 211c and is guided by the latching protrusion 326 to the ECU housing 211, And is fixed to the flat plate portion 211b.

이와 더불어, 걸림부(320)의 외주면에는 체결홀(211c)에 용이하게 끼워지도록 걸림부의 외주면 일부가 삭제되어 하나 이상의 평면부(324)가 형성되며, 또한, 체결홀(211c)에 용이하게 끼워지도록 상측으로 개방된 홈(322)이 형성된다.In addition, a part of the outer circumferential surface of the engaging portion is removed so as to be easily fitted into the engaging hole 211c on the outer circumferential surface of the engaging portion 320, so that at least one flat surface portion 324 is formed. A groove 322 opened upward is formed.

홈(322)은 고정돌기(350)가 체결홀(211c)에 삽입시 걸림부(320)의 외경이 줄어들며 수축될 수 있도록 형성된다.The groove 322 is formed in such a manner that the outer diameter of the latching part 320 can be reduced and contracted when the locking protrusion 350 is inserted into the locking hole 211c.

즉, 지지부(310)의 일측에 연결부(330)로 연결된 걸림부(320)가 형성되되, 체결홀(211c)에 용이하게 끼워지도록 걸림부(320)에 평면부(324)와 홈(322)이 형성되고, 유합블록(230)과 ECU 하우징(211)의 결합시 슬리브(221a)를 지지하도록 고정돌기(350)가 체결홀(211c)에 삽입되어 결합된 상태로 유합블록(230)과 ECU 하우징(211)이 조립되는 것이다.That is, the support portion 310 is provided with a coupling portion 320 connected to one side of the support portion 310 and the plane portion 324 and the groove 322 are formed in the coupling portion 320 so as to be easily inserted into the coupling hole 211c. And the fixing protrusion 350 is inserted into the coupling hole 211c to support the sleeve 221a when the fusion block 230 and the ECU housing 211 are coupled to each other, The housing 211 is assembled.

이와 같이, 유압블록(230)과 ECU 하우징(211)의 결합시 슬리브(221a)를 지지하도록 소음흡수부재(300)가 ECU 하우징(211)에 결합되어 조립됨으로써, 조립을 위한 작업효율성과 생산효율성이 보다 향상되는 것이다.Since the noise absorbing member 300 is assembled to the ECU housing 211 so as to support the sleeve 221a when the hydraulic block 230 and the ECU housing 211 are coupled to each other, Is better than this.
