본 고안은 스프링정수 가변식 에어스프링에 관한 것으로서, 특히 외부에서 별도의 조정수단을 제공하여 스프링정수를 가변가능케 하여 운전자의 취향 및 차량의 상태에 따라 차고(車高)를 조절할 수 있도록 하는 스프링정수 가변식 에어스프링에 관한 것이다.The present invention relates to a spring constant variable air spring, and in particular, by providing a separate adjustment means from the outside to make the spring constant variable so that the spring constant to adjust the height according to the driver's taste and the state of the vehicle It relates to a variable air spring.
통상적으로 자동차의 현가장치에는 여러가지 장치가 구비되는데, 예를 들면 충격완화를 위한 쇽업소오버 또는 그와 유사한 기능을 수행하는 에어스프링 등이 구비되어 있다. 본 고안은 상기 에어스프링에 관한 것으로서, 종래에는 제1도에 도시된 바와 같이 내측에 압력실(12)을 구비하는 챔버(10)의 일측에 완충능력을 갖는 댐퍼(20)를 설치하고 댐퍼(20)와 챔버(10)를 다이아프램(30)으로 밀폐연결하여 상기 압력실내에 충진되는 공기압 및 댐퍼에 의해 항시 일정한 스프링정수를 보유하게 되는 것이 개발되어 있다.Typically, a suspension device of a vehicle is provided with various devices, for example, shock absorbers for shock alleviation or an air spring for performing a similar function. The present invention relates to the air spring, and conventionally, as shown in FIG. 1, a damper 20 having a shock absorbing capacity is installed on one side of the chamber 10 having a pressure chamber 12 therein, and a damper ( 20) and the chamber 10 are hermetically connected to the diaphragm 30 to maintain a constant spring constant at all times by the air pressure and damper filled in the pressure chamber.
그러나 이와 같은 공기스프링은 스프링정수가 항시 일정하게 유지되므로 필요에 따라 차량의 높이를 변화시키거나 스프링정수를 변화시킬 필요가 있을 경우에 이를 실현할 수 없는 문제를 갖고 있었다. 즉 예를 들면 주행도로의 조건이 굴곡져 있어 차고를 높이고자 할 경우 또는 차량에 많은 옵션이 장착되어 중량이 표준이상으로 늘어났을 경우등과 같이 상대적으로 차고가 낮아져 이를 보상해줄 필요가 있는 경우등에 적절하게 대처할 수 없는 문제를 갖고 있는 것이었다.However, such an air spring has a problem that can not be realized when it is necessary to change the height of the vehicle or change the spring constant, as the spring constant is always kept constant. That is, for example, when the road conditions are curved to increase the garage, or when the vehicle is equipped with many options and the weight is increased above the standard, it is necessary to compensate for the decrease in the garage. There was a problem that could not be properly addressed.
한편 제2도에는 종래의 또 다른 예로서 완충능력을 보유한 댐퍼(20)와 다이아프램(30) 사이에 습동가이드(40)를 설치한 구성을 갖는 것이 있는데, 이 또한 스프링정수를 변화시킬 수 있는 수단이 구비되어 있지 않으므로 상기와 같은 문제를 그대로 갖고 있는 것이다.On the other hand, Figure 2 has a configuration in which the sliding guide 40 is installed between the damper 20 and the diaphragm 30 having a buffer capacity as another conventional example, which can also change the spring constant Since a means is not provided, it has the same problem as mentioned above.
이에 본 고안은 상기와 같은 제반 문제를 감안하여 안출된 것으로서, 그 목적은 별도의 조정수단을 제공하여 스프링정수를 가변가능케 하여 운전자의 취향 및 차량의 상태에 따라 차고(車高)를 조절할 수 있도록 하는 스프링정수 가변식 에어스프링을 제공함에 있다.The present invention has been devised in view of the above problems, and its purpose is to provide a separate adjustment means so that the spring constant is variable so that the height can be adjusted according to the driver's taste and the state of the vehicle. To provide a spring constant variable air spring.
이러한 본 고안의 목적은 습동가이드의 하단 외주에는 나사부를 형성하고, 그 나사부의 상부에 끼워짐과 동시에 상기 나사부에 결합되는 고정너트에 의해 가압되는 조정부재를 구비하여 달성될 수 있다.The purpose of the present invention can be achieved by forming a screw portion on the lower outer periphery of the sliding guide, and is fitted to the upper portion of the sliding guide and at the same time having an adjusting member pressed by a fixing nut coupled to the screw portion.
즉, 조정부재를 다이아프램의 외측에 가압고정하여 압력실의 압력을 상승시켜 상대적으로 스프링정수를 변화시키게 되고 부재의 형태변화에 따라 그 스프링정수의 변화량 또한 결정토록 하여 이루어지는 것이다.That is, the adjustment member is fixed to the outside of the diaphragm to increase the pressure in the pressure chamber to relatively change the spring constant and to change the spring constant according to the shape change of the member.
이하 본 고안의 바람직한 실시예를 첨부도면에 의거하여 좀더 구체적으로 설명하면 다음과 같다. 내측에 압력실(12)을 구비하는 챔버(10)의 일측 완충능력을 갖는 댐퍼(20)를 설치하고, 댐퍼(20)의 외주연에 습동가이드(40)가 구비되어 있다. 그리고 일측은 상기 챔버(10)에 밀폐고정되고, 타측은 상기 습동가이드(40)의 상단에 밀폐고정되는 다이아프램(30)이 구비되어 있다.Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings. A damper 20 having a shock absorbing capability of one side of the chamber 10 having a pressure chamber 12 is provided inside, and a sliding guide 40 is provided on the outer periphery of the damper 20. And one side is fixed to the chamber 10, the other side is provided with a diaphragm 30 is hermetically fixed to the upper end of the sliding guide (40).
또한 상기 습동가이드(40)의 하단에는 외주에는 나사부(42)가 형성되어 있고, 그 나사부의 상부에 끼워짐과 동시에 상기 나사부에 결합되는 고정너트(44)에 의해 가압되는 조정부재(50)가 구비되어 있다.In addition, the lower end of the sliding guide 40 is formed with a threaded portion 42 on the outer periphery, the adjustment member 50 is pressed by the fixing nut 44 which is fitted to the upper portion of the threaded portion and coupled to the threaded portion It is provided.
상기 조정부재(50)는 그 내경이 상기 습동가이드(40)의 외경에 결합 가능하게 구성되어 제4도의 (a)도와 같이 장고형(51) 및 (b)도와 같은 테이퍼형(52), (c)도와 같은 역테이퍼형(53), (d)도와 같은 원통형(54), 그리고 (e)도와 같은 항아리형(55) 등의 여러종류를 구성하여 스프링정수변화량을 선택할 수 있게 된다.The adjusting member 50 is configured such that its inner diameter can be coupled to the outer diameter of the sliding guide 40 so that the tapered type 52 as shown in (a) of FIG. The number of spring constant changes can be selected by constructing various types such as an inverse taper shape 53 as shown in c), a cylinder 54 as shown in (d), and a jar shape 55 as shown in (e).
이와 같은 구성을 갖는 본 고안은 도로조건 및 차량의 상태에 따라 부합되는 조정부재(50)를 습동가이드(40)의 외측에 끼운후 고정너트(44)로 가압고정하게 되면 스프링상수는 습동가이드(40)의 형상에 따라 변화하게 된다.The present invention having such a configuration is inserted into the outer side of the sliding guide 40, the adjustment member 50 according to the road conditions and the state of the vehicle and then fixed by the fixing nut 44, the spring constant is sliding guide ( It changes according to the shape of 40).
상술한 바와 같이 본 고안에 따른 스프링정수 가변식 에어스프링은 습동가이드의 외측에 조정부재를 제공하고 이를 고정너트로써 가압고정토록 하여 습동가이드의 형상에 따라 스프링정수를 변화시킬 수 있게 되어 운전자의 취향은 물론 도로의 조건 및 차의 중량에 따라 적절한 스프링을 보유토록 하고 나아가서 주행안정성을 향상시킬 수 있는 효과를 갖는 것이다.As described above, the spring constant variable air spring according to the present invention provides an adjustment member on the outside of the sliding guide, which is fixed by pressing the nut as a fixing nut, thereby changing the spring constant according to the shape of the sliding guide. Of course, according to the conditions of the road and the weight of the car to have an appropriate spring and further has the effect of improving the driving stability.
