감압노이즈 저감형 펌프하우징장치{PUMP HOUSING DEVICE FOR DECOMPRESSION NOISE REDUCTION}TECHNICAL FIELD [0001] The present invention relates to a pump housing device for reducing pressure noise,

본 발명은 펌프하우징장치에 관한 것으로서, 보다 상세하게는 휠 감압시 발생하는 감압노이즈를 흡수하여 정숙성을 향상시킬 수 있는 감압노이즈 저감형 펌프하우징장치에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pump housing device, and more particularly, to a reduced-pressure noise reduction type pump housing device capable of absorbing reduced-pressure noise generated when a wheel is depressurized to improve quietness.

일반적으로, 차량의 브레이크장치는, 브레이크 페달 작동에 의해 발생된 제동압을 휠브레이크에 구비되는 휠실린더로 전달하여 차량을 감속시키거나 정지시킨다.Generally, a braking device of a vehicle transmits braking pressure generated by a brake pedal operation to a wheel cylinder provided in a wheel brake to decelerate or stop the vehicle.

브레이크장치를 사용하는 경우, 차량의 주행 특성 및 노면의 상태에 따라 미끄러지는 슬립(Slip)현상이 발생할 수 있다.When a braking device is used, a slip phenomenon that slips depending on the running characteristics of the vehicle and the state of the road surface may occur.

이와 같은 슬립 현상을 방지하기 위해 휠 브레이크의 제동압을 전자적으로 제어하는 브레이크가 널리 사용되며, 이러한 브레이크장치를 ABS(Anti Lock Brake System) 브레이크장치라 한다.In order to prevent such a slip phenomenon, a brake for electronically controlling the braking pressure of the wheel brake is widely used. Such a brake apparatus is called an ABS (Anti Lock Brake System) brake apparatus.

ABS 브레이크장치는, 차량의 슬립율에 따라 차륜을 제동하는 휠실린더 내의 압력이 증압, 감압 및 유지되어 차륜의 록이 방지된다.In the ABS brake device, the pressure in the wheel cylinder for braking the wheel in accordance with the slip ratio of the vehicle is increased, reduced, and maintained to prevent locking of the wheel.

이와 같은 ABS 브레이크장치의 제어에 있어서, 휠실린더의 증압을 위해 마스터실린더 내의 브레이크오일을 휠실린더로 공급한다.In the control of the ABS braking device, brake oil in the master cylinder is supplied to the wheel cylinder for increasing the pressure of the wheel cylinder.

또한, 휠실린더의 감압을 위해, 휠실린더 내의 브레이크오일을 인렛밸브 측으로 배출하고, 일부는 축압기와 유압펌프를 통해 마스터실린더로 배출한다.Further, in order to reduce the pressure in the wheel cylinder, the brake fluid in the wheel cylinder is discharged to the inlet valve side, and a part is discharged to the master cylinder through the accumulator and the hydraulic pump.

이를 위해, 마스터실린더에서 휠실린더로 연결된 브레이크라인에 인렛밸브를 설치하며, 휠실린더에서 오일이 환류하는 환류라인에 아웃렛밸브를 설치한다.To this end, an inlet valve is provided in the brake line connected to the wheel cylinder in the master cylinder, and an outlet valve is provided in the return line in which the oil circulates in the wheel cylinder.

이러한 브레이크라인과 환류라인은 펌프하우징장치의 내측에 설치되며, 인렛밸브와 아웃렛밸브를 포함한 밸브부는 펌프하우징에 결합된다.The brake line and the return line are installed inside the pump housing unit, and the valve unit including the inlet valve and the outlet valve is coupled to the pump housing.

환류라인(12)에서 분기되어 감압공간(22)을 형성하는 감압홈부(20)는, 충격흡수부(40)의 이동거리 및 수격현상으로 발생하는 충격파인 감압노이즈의 크기 등을 고려하여 설치위치 및 형상 등이 결정된다.The depressurizing groove portion 20 which branches off from the reflux line 12 and forms the depressurized space 22 is provided at a predetermined position in consideration of the moving distance of the impact absorbing portion 40 and the size of the reduced pressure noise, And the like are determined.

충격흡수부(40)의 하측에 있는 브레이크오일(55)이 충격흡수부(40)의 상측으로 이동되는 통로인 이동홀부(44)는, 몸체부(42)의 중앙에 돌출된 형상으로 설치된다.The moving hole portion 44 which is a passage through which the brake oil 55 under the shock absorbing portion 40 is moved to the upper side of the impact absorbing portion 40 is provided in a protruding shape at the center of the body portion 42 .

환류라인(12)을 따라 흐르는 브레이크오일(55)은 개방된 아웃렛밸브(52)를 통해 축압기(30)로 이동되어 충격이 흡수된 후, 유압펌프를 통해 마스터실린더 측으로 배출된다.The brake oil 55 flowing along the reflux line 12 is moved to the accumulator 30 via the open outlet valve 52 to absorb the impact and then discharged to the master cylinder side via the hydraulic pump.

휠 감압의 중지를 위해 아웃렛밸브(52)가 닫히면, 환류라인(12)의 제1관로(14)를 통해 이동되는 브레이크오일(55)에 충격파인 감압노이즈가 발생된다.When the outlet valve 52 is closed to stop the decompression of the wheel, a decompression noise, which is a shock wave, is generated in the brake oil 55 which is moved through the first line 14 of the return line 12.

감압노이즈는 충격흡수부(40)의 몸체부(42)를 하측으로 가압하게 되며, 충격흡수부(40)는 하측으로 이동하면서 충격흡수부(40) 하측의 브레이크오일(55)을 이동홀부(44)를 통해 상측으로 배출한다.The decompression noise presses the body portion 42 of the shock absorbing portion 40 downward and the impact absorbing portion 40 moves downward to move the brake oil 55 under the shock absorbing portion 40 to the moving hole portion 44 to the upper side.

충격흡수부(40)의 하측 이동 및 이동홀부(44)를 통한 브레이크오일(55)의 상측 분사로 감압노이즈가 감소한다.The decompression noise is reduced due to the downward movement of the shock absorbing portion 40 and the upward injection of the brake oil 55 through the moving hole portion 44. [

상술한 바와 같은 구성에 의하면, 일 실시예에 따른 감압노이즈 저감형 펌프하우징장치(1)는, 아웃렛밸브(52)의 동작으로 감압노이즈가 발생할 때, 감압홈부(20)를 따라 이동되는 충격흡수부(40)가 감압노이즈를 흡수하여, 환류라인(12)에서 발생하는 진동 및 소음을 저감시킬 수 있다.The reduced pressure noise reduction type pump housing apparatus 1 according to the embodiment is configured such that when the decompression noise occurs due to the operation of the outlet valve 52, The portion 40 absorbs the decompression noise, and vibration and noise generated in the reflux line 12 can be reduced.

본 발명은 도면에 도시된 실시예를 참고로 하여 설명되었으나, 이는 예시적인 것에 불과하며, 당해 기술이 속하는 분야에서 통상의 지식을 가진 자라면 이로부터 다양한 변형 및 균등한 타 실시예가 가능하다는 점을 이해할 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

또한, 차량의 브레이크장치에 사용되는 감압노이즈 저감형 펌프하우징장치를 예로 들어 설명하였으나, 이는 예시적인 것에 불과하며, 브레이크를 사용하는 다른 종류의 기계장치에도 본 발명에 의한 감압노이즈 저감형 펌프하우징장치가 사용될 수 있다.In addition, although a reduced-pressure noise reduction type pump housing apparatus used for a brake apparatus of a vehicle has been described as an example, the present invention is merely an example, and other types of mechanical apparatuses using brakes are also applicable to a reduced- Can be used.

따라서, 본 발명의 진정한 기술적 보호범위는 특허청구범위에 의해서 정하여져야 할 것이다.
