본 발명은 차량의 주행저항을 이용한 진공발생장치에 관한 것으로, 보다 상세하게는 차량의 주행시 통과되는 바람을 유입시켜 진공을 발생할 수 있도록 된 차량의 주행저항을 이용한 진공발생장치에 관한 것이다. The present invention relates to a vacuum generating apparatus using a running resistance of a vehicle, and more particularly, to a vacuum generating apparatus using a running resistance of a vehicle to generate a vacuum by introducing a wind passing through when the vehicle runs.                         

일반적으로 차량의 경우 운전자의 조작 시 그 힘을 배력시켜 조작감을 좋게 하면서 원하는 성능을 발휘하도록 유압을 이용하게 되는데 이와 같은, 유압을 이용하는 장치로서 대표적인 것이 파우워 스티어링이나 브레이크 및 클러치시스템이 있게 된다.In general, in the case of a vehicle, the hydraulic power is used to exert its force during operation of the driver to improve the feeling of operation and to achieve a desired performance. Such a device using the hydraulic pressure is a power steering, a brake, and a clutch system.

이와 같은 배력 장치들중, 브레이크와 클러치시스템은 오일을 가압하여 유압을 발생하기 위해 진공을 매개로 작동되는 부스터를 필요로 하고 이와 같은 부스터의 진공을 발생하는 진공펌프와 같은 장치가 반드시 요구되는데 이러한, 진공발생장치는 도 1에 도시된 바와 같이 운전석에 구비된 브레이크와 클러치페달의 조작시 작동되는 부스터(10)의 잔존 에어를 배출하면서 진공을 형성하는 진공탱크(20)와, 브레이크나 클러치의 조작시 함께 작동되어 상기 진공탱크(20)의 에어를 흡입하여 빠르게 진공을 생성하는 진공펌프(30)로 이루어진다.Among these power units, the brake and clutch system require a vacuum-operated booster to pressurize oil to generate hydraulic pressure, and a device such as a vacuum pump for generating a vacuum of such booster is required. The vacuum generator includes a vacuum tank 20 for forming a vacuum while discharging the remaining air of the booster 10 operated when the brake and the clutch pedal provided in the driver's seat, as shown in FIG. It is composed of a vacuum pump 30 that is operated together during operation to suck the air of the vacuum tank 20 to generate a vacuum quickly.

즉, 운전자의 브레이크나 클러치의 페달 조작에 의해 진공펌프(30)가 작동되면 고속으로 회전되는 진공펌프(30)가 진공탱크(20)와 부스터(10)의 에어를 뽑아 대기로 배출하게 되므로 결국, 상기 진공탱크(20)와 부스터(10)사이의 진공라인에는 1기압(760mmHg)의 부압이 발생되고 이 부압에 의해 부스터(10)에서 배력 작용을 하게 된다.That is, when the vacuum pump 30 is operated by the pedal operation of the driver's brake or clutch, the vacuum pump 30 which rotates at high speed extracts air from the vacuum tank 20 and the booster 10 and discharges it to the atmosphere. In the vacuum line between the vacuum tank 20 and the booster 10, a negative pressure of 1 atm (760 mmHg) is generated, and the negative pressure acts as a boosting force in the booster 10.

이때, 상기 부스터(10)의 작동으로 인해 유입되는 대기압은 진공펌프(30)의 작동으로 인해 지속적으로 배출되면서 정상 작동될 수 있는 대기압 차이를 발생하게 된다.At this time, the atmospheric pressure introduced due to the operation of the booster 10 generates a difference in atmospheric pressure that can be normally operated while being continuously discharged due to the operation of the vacuum pump 30.

그러나, 이와 같은 진공을 형성하는 진공펌프(30)는 각각 정해진 용량을 갖 으면서 통상 약 90%정도의 효율성능을 가지므로 진공탱크(20)내의 압력은 약 700mmHg정도를 유지하게 되지만, 엔진의 아이들(Idle)시에는 진공탱크(20)의 부압 생성시간이 상대적으로 더디는 현상이 발생되고 또한, 주행중 연속적으로 페달을 조작하게 되면 진공압이 약 500mmHg 정도로 급격히 저하되어 제동시 브레이크 페달의 답력이 급격히 증대되면서 제동력이 저하됨은 물론 클러치 페달의 답력도 급격하게 변동되는 문제가 있게 된다.However, since the vacuum pumps 30 forming such a vacuum each have a predetermined capacity and generally have an efficiency of about 90%, the pressure in the vacuum tank 20 is maintained at about 700 mmHg, but the engine idle During idle, the negative pressure generation time of the vacuum tank 20 is relatively slow. Also, if the pedal is operated continuously while driving, the vacuum pressure drops rapidly to about 500 mmHg. As it increases, the braking force is lowered, as well as the clutch pedal's pedaling force is also rapidly changed.

또한, 차량의 주행 중 브레이크 페달을 짧은 시간에 반복적으로 자주사용하는 경우 엔진의 아이들시와 같이 진공탱크(20)의 부압 생성시간이 늦고 빈번한 사용으로 인한 부족에 의해 제동력 부족이 발생되어 브레이크의 제동 성능이 저하되는 단점이 있게 된다.In addition, when the brake pedal is frequently used repeatedly during driving of the vehicle, a negative pressure generation time of the vacuum tank 20 is delayed and the braking force is insufficient due to frequent use, such as when the engine is idle. There is a disadvantage of degrading performance.

이에 본 발명은 상기와 같은 점을 감안하여 발명된 것으로, 차량의 주행 중 고속으로 차량을 통과하는 주행풍을 유입시켜 진공펌프와 함께 진공탱크의 부압을 형성시켜 진공탱크의 부압 생성시간을 단축하면서 빈번한 부압의 이용시에도 충분한 부압을 제공하여 부스터의 성능을 저하하지 않도록 함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above, while driving the wind flowing through the vehicle at high speed while driving the vehicle to form the negative pressure of the vacuum tank together with the vacuum pump, while reducing the negative pressure generation time of the vacuum tank. It is an object of the present invention to provide sufficient negative pressure even when using frequent negative pressure so as not to degrade the performance of the booster.

상기와 같은 목적을 달성하기 위한 본 발명은, 진공발생장치가 운전석에 구비된 브레이크와 클러치페달의 조작 시 작동되는 부스터의 잔존 에어를 유입하는 진공탱크의 에어를 흡입하여 빠르게 진공을 생성하는 진공펌프와, 이 진공펌프의 전단에서 진공탱크에 연통되어 유입되는 차량의 주행풍에 의해 회전되면서 진공탱크의 부압을 생성시키는 부가수단으로 이루어진 것을 특징으로 한다.The present invention for achieving the above object, a vacuum pump for generating a vacuum quickly by inhaling the air of the vacuum tank for introducing the remaining air of the booster which is operated during the operation of the brake pedal and the clutch pedal provided in the driver's seat And an additional means for generating a negative pressure of the vacuum tank while being rotated by the running wind of the vehicle which is communicated with the vacuum tank at the front end of the vacuum pump.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 차량의 주행저항을 이용한 진공발생장치의 구성도를 도시한 것인바, 본 발명의 진공발생장치는 운전석에 구비된 브레이크와 클러치페달의 조작 시 작동되는 부스터(10)의 잔존 에어를 유입하는 진공탱크(20)의 에어를 흡입하여 빠르게 진공을 생성하는 진공펌프(30)와, 이 진공펌프(30)의 전단에서 진공탱크(20)에 연통되어 유입되는 차량의 주행풍에 의해 회전되면서 진공탱크(20)의 부압을 생성시키는 부가수단(40)으로 이루어진다.Figure 2 shows the configuration of the vacuum generating device using the driving resistance of the vehicle according to the present invention, the vacuum generator of the present invention is a booster (10) of the operation when operating the brake pedal and clutch pedal provided in the driver's seat The vacuum pump 30 which sucks the air of the vacuum tank 20 which introduces residual air, and rapidly produces a vacuum, and the running wind of the vehicle which is communicated with the vacuum tank 20 at the front end of the vacuum pump 30 and flows in. Rotation by means of the additional means 40 for generating a negative pressure of the vacuum tank 20.

여기서, 상기 부가수단(40)은 유입되는 차량의 주행풍에 의해 고속으로 회전하는 구동터빈(41)과, 이 구동터빈(41)에 연결축(42)을 매개로 결합되어 상기 진공탱크(20)에 연결된 진공라인의 연장부위에 구비된 종동터빈(43)으로 이루어진다.Here, the additional means 40 is coupled to the drive turbine 41 which rotates at a high speed by the driving wind of the inflow vehicle, and the connecting shaft 42 to the drive turbine 41 through the vacuum tank 20 It consists of a driven turbine 43 provided on the extension of the vacuum line connected to).

또한, 상기 진공탱크(20)와 부가수단(40)사이의 진공라인에는 진공탱크(20)에서 부가수단(40)쪽으로 만 흐르는 일 방향의 체크밸브(50)가 구비되는 한편, 상기 진공탱크(20)와 진공펌프(30)사이의 진공라인에는 진공탱크(20)에서 진공펌프(30)쪽으로 만 흐르는 일 방향의 체크밸브(50')가 구비되어진다.In addition, the vacuum line between the vacuum tank 20 and the additional means 40 is provided with a check valve 50 in one direction flowing only from the vacuum tank 20 toward the additional means 40, while the vacuum tank ( The vacuum line between the vacuum pump 20 and the vacuum pump 30 is provided with a check valve 50 'in one direction flowing only from the vacuum tank 20 toward the vacuum pump 30.

이에 따라, 전술한 종래의 경우와 같이 운전자의 브레이크나 클러치의 페달 조작에 의해 진공펌프(30)가 작동되면 고속으로 회전되는 진공펌프(30)가 진공탱크(20)와 부스터(10)의 에어를 뽑아 대기로 배출하게 되므로 결국, 상기 진공탱크(20)와 부스터(10)사이의 진공라인에는 1기압(760mmHg)의 부압이 발생되고 이 부압에 의해 부스터(10)에서 배력 작용을 하게 된다. Accordingly, when the vacuum pump 30 is operated by the pedal operation of the driver's brake or clutch as in the conventional case described above, the air of the vacuum tank 20 and the booster 10 is rotated at a high speed. Since the air is discharged into the atmosphere, a negative pressure of 1 atm (760 mmHg) is generated in the vacuum line between the vacuum tank 20 and the booster 10, and the booster 10 acts as a booster by the negative pressure.                     

한편, 브레이크 페달이나 클러치 페달을 조작하지 않고 차량이 주행 상태인 경우에는 주행중인 차량으로 유입되는 주행풍을 매개로 부가수단(40)의 구동터빈(41)이 고속으로 회전되면서 종동터빈(43)을 회전시키게 되므로, 이 종동터빈(43)의 회전에 의해 진공탱크(20)의 에어를 외부로 배출하여 부압을 생성하게 된다.On the other hand, when the vehicle is in a driving state without operating the brake pedal or the clutch pedal, the driven turbine 43 of the additional means 40 is rotated at high speed by the driving wind flowing into the running vehicle while the driven turbine 43 is rotated at high speed. Since it rotates, the air of the vacuum tank 20 is discharged to the outside by the rotation of the driven turbine 43 to generate a negative pressure.

즉, 차량의 주행에 의해 발생되는 주행풍에 의해 고속으로 회전되는 종동터빈(43)이 진공탱크(20)에 연결된 진공라인을 통해 에어를 지속적으로 배출하게 되므로, 상기 진공펌프(30)의 작동이 없이도 진공탱크(20)의 부압을 어느 정도 생성하게 되고 결국, 페달의 조작이 빈번하더라도 진공펌프(30)에 의해 생성되는 진공에 주행풍에 의해 작동되는 부가수단(40)에 의한 진공의 생성으로 인해 부스터(10)에 요구되는 부압이 결코 부족하지 않게 되는 것이다.That is, since the driven turbine 43 rotated at high speed by the driving wind generated by the driving of the vehicle continuously discharges air through the vacuum line connected to the vacuum tank 20, the operation of the vacuum pump 30 Without this, the negative pressure of the vacuum tank 20 is generated to some extent. Consequently, even if the pedal is frequently operated, the vacuum is generated by the additional means 40 operated by the driving wind in the vacuum generated by the vacuum pump 30. Due to this, the negative pressure required for the booster 10 will never be insufficient.

이상 설명한 바와 같이 본 발명에 의하면, 차량의 주행 시 외부의 에어를 유입시켜 진공탱크의 부압을 생성하게 되므로 진공펌프가 작동되지 않더라도 진공탱크에 지속적으로 부압을 생성하여 페달의 조작에 따라 진공펌프가 작동될 때 진공탱크의 부압생성이 상대적으로 빠르게 이루어짐은 물론 빈번한 페달의 조작에 따른 부압 저감을 보충하여 브레이크 조작시 제동 성능의 저하를 방지할 수 있는 효과가 있게 된다.As described above, according to the present invention, when the vehicle is driven, the external air is introduced to generate the negative pressure of the vacuum tank, so that the vacuum pump is continuously generated under the operation of the pedal even if the vacuum pump is not operated. When operating, the negative pressure generation of the vacuum tank is made relatively fast, and the negative pressure reduction caused by frequent pedal operation is compensated for, thereby preventing the deterioration of braking performance during brake operation.
