Description

차량용 차고 조절장치Car Garage Controls

본 발명은 차고 조절장치에 관한 것으로서, 보다 상세하게는 차량이 경사진 도로 주행시 차고가 무게중심에 따라 변경 가능하도록 이루어진 차고 조절장치에 관한 것이다.The present invention relates to a garage adjustment apparatus, and more particularly, to a garage adjustment device configured to be changed according to the center of gravity when the vehicle is driving on a slope road.

일반적으로 서스펜션은 차축과 차체 사이에 장착되어 차량이 주행할 때 차축이 노면으로부터 바퀴를 통해 받는 충격이나 진동을 차체에 직접 전달되지는 것을 차단하여 차체나 화물의 손상을 방지하고, 승차감을 좋게 하는 장치이다.In general, the suspension is mounted between the axle and the body to prevent the axle from being directly transmitted to the body of the shock or vibration received from the road surface by the wheels when the vehicle is running, thereby preventing damage to the body or cargo and improving ride comfort. Device.

이러한 현가장치는 노면으로부터 바퀴를 통해 전달되는 진동 및 충격을 흡수하는 섀시 스프링과, 이 섀시 스프링의 고유진동을 흡수하는 쇽 업소버로 이루어진다.This suspension consists of a chassis spring that absorbs vibrations and shocks transmitted from the road surface through wheels, and a shock absorber that absorbs the natural vibrations of the chassis springs.

상기 섀시 스프링으로 승용차에 주로 사용되는 코일스프링, 토오션 바아 스프링이 있고, 중,대형 차량에는 판 스프링이나 에어스프링등이 주로 사용된다.As the chassis spring, there are coil springs and torsion bar springs that are mainly used in passenger cars, and leaf springs or air springs are mainly used in medium and large vehicles.

그러나 상기한 바와 같은 서스펜션은 섀시 스프링의 스프링 상수가 항상 일정하게 고정되어 있고, 또한 그 높이가 일정하게 고정되어 있으므로 차량이 오르막길에서는 차량의 후방이 다운되고, 내리막길에서는 차량의 전방측이 다운되어 조정안정성 및 조향 성능이 저하됨은 물론 승차감이 저하되는 문제점이 있다.However, in the suspension as described above, since the spring constant of the chassis spring is always fixed constantly and its height is fixed constantly, the rear of the vehicle is down on the uphill road, and the front side of the vehicle is down on the downhill road. The steering stability and steering performance is degraded, as well as the riding comfort is reduced.

따라서 본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 차량이 오르막길을 오를 때는 후방 차고를 높여주고, 내리막길 주행시에는 전방측 차고를 높여주는 등의 도로 여건에 따라 차고를 조절할 수 있는 차량용 차고 조절장치를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, an object of the present invention is to increase the rear garage when the vehicle is going uphill, and to increase the front garage when driving downhill.

상기 개폐수단(4)은 전기적인 신호에 의해 작동 유체의 흐름을 전환시켜주는 작용을 하는 개폐밸브로서, 에어탱크(26)로 부터 공급되는 에어를 상기 차고 센싱수단(2)의 신호에 의해 차고 조절수단(6)을 공급하거나 차단하는 역할을 한다.The opening and closing means (4) is an opening and closing valve that serves to switch the flow of the working fluid by an electrical signal, the garage is supplied to the air supplied from the air tank 26 by the signal of the garage sensing means (2) It serves to supply or block the adjusting means (6).

이러한 개폐수단은 에어탱크(26)와 연결되는 유로(28)와, 차고 조절수단(6)으로 에어를 공급하는 유로(30)와, 에어가 배출되는 유로(32)가 형성된 밸브바디(34)와, 이 밸브바디(34) 내측을 직선왕복이동하고, 각각의 유로의 개폐작용을 하는 랜드(42),(40)가 형성된 밸브스플(28)과, 이 밸브스풀(38)의 타측단과 연결되어 상기 차고 센싱수단(2)의 신호에 따라 밸브스플(38)을 수직왕복 이동시키는 솔레노이드(36)를 포함한다.The opening and closing means is a valve body 34 in which a flow path 28 connected to the air tank 26, a flow path 30 for supplying air to the garage control means 6, and a flow path 32 through which air is discharged. And a valve spool 28 formed with lands 42 and 40 for linearly reciprocating the inside of the valve body 34 and opening and closing the respective flow paths, and being connected to the other end of the valve spool 38. And a solenoid 36 which vertically reciprocates the valve spool 38 according to the signal of the garage sensing means 2.

상기 밸브스플(38)은 일측에 에어탱크(26)와 연결된 유로(28)의 개폐작용을 하는 제1랜드(40)가 형성되고, 그 끝단측에 에어가 배출되는 유로(32)의 개폐작용을 하는 제2랜드(42)가 형성된다.The valve spring 38 has a first land 40 for opening and closing the flow path 28 connected to the air tank 26 is formed on one side, the opening and closing action of the flow path 32 through which air is discharged at the end side thereof. A second land 42 is formed.

이러한 개폐수단(4)은 차량의 전방측과 후방측에 각각 동일한 구조로 형성된다.The opening and closing means 4 are formed in the same structure on the front side and the rear side of the vehicle, respectively.

상기 차고 조절수단(6)은 차량 각각의 차륜측에 장착된 섀시 스프링과는 별도로 각각의 차륜측에 장착되어 에어의 공급 및 배출에 따라 그 부피가 상하방향으로 부풀고, 줄고 하는 밸로우즈로 이루어진다.The garage adjustment means 6 is formed on each wheel side separately from the chassis spring mounted on each wheel side of the vehicle, and is made of bellows whose volume is inflated and reduced in accordance with the supply and discharge of air.

이와 같이 이루어진 차고 조절장치는 차량이 경사로를 오를 경우 차량의 전방이 들리게 되면 차고 센싱수단의 작동로드(10)가 그 무게 중심에 의해 회전하여 접점(16)과, 접점(22) 사이를 연결하여 후방측 개폐수단(5)에 전원을 인가시키면 에어탱크(26)와 연결되는 유로(28)와 차고 조절수단(6)과 연결되는 유로(30) 서로 연통시켜 후방 좌우측에 장착된 차고 조절수단(6)에 에어를 공급한다.The height adjustment device made in this way is connected to the contact point 16 and the contact point 22 by rotating the operating rod 10 of the garage sensing means by the center of gravity when the front of the vehicle is lifted when the vehicle climbs the ramp.
