The air bag 20 is disposed between the upper ends of the shock absorbers 10 and 11 and the vehicle body 30.

상기한 공기주머니(20)는 별도의 지지판(21,22)으로 아래위를 지지하는데, 아래의 지지판(21)은 상기 쇽업쇼버(10,11)의 상단에 고정하고, 위에 형성되는 지지판(22)는 차체(30)에 고정설치한다.The air bag 20 is supported up and down by separate support plates (21, 22), the lower support plate 21 is fixed to the upper end of the shock absorbers (10, 11), the support plate 22 is formed above Is fixed to the vehicle body (30).

특히, 후륜측에 형성되는 쇽업쇼버(11)의 하단은 뒤차축(50)에 별도의 홀더(51)를 형성하여 상기 홀더(51)에 회동가능하게 힌지결합한다. 그리고 후륜의 쇽옵쇼버(11) 상단이 위치하는 차체(30)에는 차체(30)와 일체로 호형상의 가이드레일(31)을 형성하는데, 상기한 가이드레일(31)에는 "T"자형의 플레이트(33)가 이동될 수 있도록 가이드홈(32)을 형성한다. 그리고 이 가이드홈(32)은 차체길이 방향을 따라 형성하며, 또한 뒤차축을 중심으로 한 원호의 궤적을 따라 형성한다.In particular, the lower end of the shock absorber 11 formed on the rear wheel side is formed by a separate holder 51 on the rear axle 50 is hinged rotatably to the holder 51. In addition, an arc-shaped guide rail 31 is integrally formed with the vehicle body 30 in the vehicle body 30 at which the upper end of the shock absorber 11 of the rear wheel is located. The guide rail 31 has a "T" shape. The guide groove 32 is formed to move the plate 33. The guide groove 32 is formed along the vehicle body length direction, and is also formed along the trajectory of the arc around the rear axle.

상기한 "T"자형의 플레이트(33)의 날개부(33a)는 가이드홈(32)에 끼우며, 그 하단은 상기한 공기주머니(20)의 상부에 형성된 상부지지부(22)에 고정되게 형성한다.The wing portion 33a of the “T” shaped plate 33 is inserted into the guide groove 32, and the lower end thereof is fixed to the upper support portion 22 formed on the upper portion of the air bag 20. do.

상기한 앞뒤의 쇽업쇼버(10,11)의 상단에 설치한 각각의 공기주머니(20)의 내부에는 공기가 채워지는데, 공기주머니(20)의 일측에는 외부의 공기 및 타공기주머니들로부터 이동하여 오는 공기가 유입되는 공기유입공(23)을 형성한다. 상기한 각각의 공기유입공(23)으로는 각각의 공기주머니(20)의 내부가 연통되도록 공기호스(24)로써 연결하며, 공기호스(24)의 도중에는 도 3과 같이 에어펌프(25)를 설치한다. 그리고 전륜측에 형성되는 공기주머니(20)와 후륜측의 공기주머니(20)를 연결하는 공기호스(24)의 도중에는 전자제어장치(ECU)에 의해 작동하는 솔레노이드밸브(26)를 형성하는 것이 바람직하다.Inside the respective air bags 20 installed on the upper and rear shock absorbers 10 and 11, the air is filled, one side of the air bag 20 is moved from the outside air and other air bags It forms an air inlet hole 23 through which the incoming air flows. Each of the air inlet hole 23 is connected by the air hose 24 so that the inside of each air bag 20 communicates, the air pump 25 in the middle of the air hose 24 as shown in FIG. Install. In addition, it is preferable to form a solenoid valve 26 operated by an electronic control unit (ECU) in the middle of the air hose 24 connecting the air bag 20 formed on the front wheel side and the air bag 20 on the rear wheel side. Do.

특히 상기한 공기주머니(20)는 도면의 표현상 주름이 있는 공기주머니로 도시하였으나, 원형 혹은 타원형의 공기주머니를 장착하는 것도 가능하므로 공기주머니의 형상에 있어 제약이 있는 것은 아니다.In particular, the air bag 20 is shown as a pouch with air wrinkles in the representation of the drawing, it is also possible to mount a round or oval air bag is not limited in the shape of the air bag.

그리고 일반적인 운행의 경우에 상기 공기주머니(20) 내부에 채워지는 공기량은 약 60~80% 정도를 유지하는 것이 바람직하다.And in the case of normal operation, the amount of air filled in the air bag 20 is preferably maintained about 60 to 80%.

상기와 같이 쇽업쇼버와 차체 사이에 형성된 공기주머니의 작동상태를 도면과 함께 설명하면 다음과 같다.The operation state of the air bag formed between the shock absorber and the vehicle body as described above with reference to the drawings as follows.

각 공기주머니(20)들에 차체가 평형을 이루도록 60~80% 범위내에서 공기를 주입한 상태에서, 예를 들어 노면이 불규칙하여 한쪽바퀴가 높은 턱을 타고 넘게 된다면 일차적으로 스프링(13)이 완충하게 되며, 계속하여 그 힘이 해당 공기주머니(20)에 작용하여 눌려지게 되므로 해당 공기주머니(20) 속의 일부 공기가 공기호스(24)를 통해 나머지 3개의 공기주머니(20)들도 분산되어 차체가 평형을 이루게 되므로서 흔들림이 크게 감소되어지게 되는 것이다.In the state in which air is injected in the range of 60 to 80% to equilibrate the body to each air bag 20, for example, if the road surface is irregular and one wheel passes over the high jaw, the spring 13 is primarily Since the force is continuously pressed to act on the corresponding air bag 20, some air in the air bag 20 is distributed through the air hose 24, the remaining three air bags 20 are also dispersed As the body is in equilibrium, the shaking is greatly reduced.

한편, 차량의 운행중에 시골길과 같이 노면이 불규칙한 도로에 접하게 되면 차체의 하부가 노면에 닿게 되거나 차량내의 승차감이 현저히 떨어지게 된다.On the other hand, if the road surface is in contact with irregular roads, such as country roads while the vehicle is in operation, the lower part of the body touches the road surface or ride comfort in the vehicle is significantly reduced.

이 때 운전자가 운전석에 구비된 에어펌프(25)의 스위치를 작동하게 되면 상기한 각각의 공기주머니(20)에는 공기가 주입되고, 주입된 공기에 의해 공기주머니(20)가 팽창하게 되어 차체는 상승하게 된다. 그러면 차체의 상승으로 인해 노면 바닥에 차량하부가 긁혀 손상되는 일이 방지되게 되어 진다.At this time, when the driver operates the switch of the air pump 25 provided in the driver's seat, air is injected into each air bag 20, and the air bag 20 is inflated by the injected air. Will rise. This prevents the underside of the vehicle from being scratched and damaged by the rise of the vehicle body.

그리고 차량의 급제동시나 급가속시에는 차량의 중량이 갑자기 앞쪽이나 뒤쪽으로 쏠리게 되어 앞쪽의 공기주머니(20)에 있던 공기가 전후방 어느 한쪽으로 이동하여 차체의 기울기를 증대시키게 되므로 급격한 쏠림에 의해 오히려 승차감이 저하될 수 있다. 이 경우 전자제어장치(ECU)는 차량이 급제동 상태이거나 급가속 상태임을 판단하고, 공기호스(24) 도중에 형성되어 있는 솔레노이드밸브(26)를 작동시켜 전후 각 공기주머니(20) 사이에 공기 이동이 일어나지 않도록 공기의 이동을 차단하게 된다.When the vehicle is suddenly braked or accelerated, the weight of the vehicle is suddenly pulled forward or backward, so that the air in the front air pocket 20 moves forward and backward to increase the inclination of the vehicle body. This can be degraded. In this case, the electronic control unit (ECU) determines that the vehicle is in a sudden braking state or a rapid acceleration state, and operates the solenoid valve 26 formed in the middle of the air hose 24 to move air between the front and rear air bags 20. It prevents the movement of air to prevent it from happening.

차량의 급제동 및 급가속 상태의 판단은 속도센서가 가속페달에 연동하여 작동하는 트로틀밸브의 개도각을 검출하는 TPS(트로틀 포지션 센서) 등에 의한 정보를 검출하여 전자제어장치(ECU)가 솔레노이드밸브(26)를 개폐제어하게 된다.Judgment of the braking and the acceleration of the vehicle is performed by detecting the information by the TPS (throttle position sensor) which detects the opening angle of the throttle valve which the speed sensor operates in conjunction with the accelerator pedal, and the ECU controls the solenoid valve ( 26) to open and close the control.

그리고 차량의 뒷자석에 사람이 많이 타게 되거나 뒤 트렁크에 짐을 많이 실게 되면 차량의 뒷부분이 축쳐져 가라앉게 되는데, 이 경우에는 운전자는 자동차 후방에 형성된 실린더를 작동시켜 뒤쪽으로 기울어져 형성된 쇽업쇼버(11)를 앞쪽으로 회동시킨다. 앞쪽으로 회동된 쇽업쇼버(11)는 차량 후방의 차고를 높이게 되므로서 차체의 수평이 이루어지게 되어 뒤자석에 사람이 많이 타거나 트렁크에 짐이 많이 실린 상태에서도 편안한 운행을 할 수 있게 된다.In addition, when a lot of people ride on the rear seat of the vehicle or load a lot of luggage in the rear trunk, the rear part of the vehicle is slumped and sinked. In this case, the driver operates the cylinder formed at the rear of the car and tilts backwards to form a shock absorber (11). ) Rotate forward. The shock absorber 11 rotated to the front is to increase the garage of the rear of the vehicle, the level of the vehicle body is made to be able to operate comfortably even in the state of riding a lot of people in the back seat or a lot of luggage in the trunk.

그리고 실린더(40)는 운전자가 스위치 조작을 통해 수동으로 할 수도 있으나, 뒷바퀴쪽에 하중센서를 달아 전자제어장치(ECU)가 자동으로 제어하도록 할 수도 있다.The cylinder 40 may be manually operated by a driver through a switch operation, but the electronic controller (ECU) may be automatically controlled by attaching a load sensor to the rear wheel.

이상과 같이 쇽업쇼버의 상단에 공기주머니를 형성하여 차체에 가해지는 충격을 완충해 주는 본 발명은 비포장도로나 노면이 고르지 못한 도로에서 차량의 승차감을 향상시킬 뿐 아니라, 급제동시나 급가속시 및 차량의 뒷좌석에 사람이 많이 타거나 트렁크에 짐을 많이 실는 경우에도 차고가 수평을 유지하도록 적절히 조정할 수 있는 효과가 있는 것이다.As described above, the present invention forms an air bag at the top of the shock absorber to buffer the shock applied to the vehicle body, and improves the riding comfort of the vehicle on an unpaved road or an uneven road, as well as during sudden braking or rapid acceleration. Even if there is a lot of people in the back seats of the car or load a lot of luggage in the trunk is the effect that can be adjusted properly to keep the garage level.
