Description

차고조정장치{high control system}Garage Control Device {high control system}

본 발명은 차고조정장치에 관한 것으로, 특히 차량의 주행속도에 따라 차체의 높이가 자동적으로 조절됨으로써 주행안정성을 향상시킬 수 있도록 된 차고조정장치에 관한 것이다.The present invention relates to a height adjustment device, and more particularly to a height adjustment device that can improve the driving stability by automatically adjusting the height of the vehicle body in accordance with the running speed of the vehicle.

일반적으로, 차량이 주행을 하게 되면 차체쪽으로 부딪치는 맞바람은 도 1에 도시된 바와 같이 차체의 상부곡면을 타고 흘러가거나 또는 차체와 지면사이의 공간을 통해 흘러가는 현상이 동시에 발생하게 된다.In general, when the vehicle travels, the upwind hitting the vehicle body flows along the upper curved surface of the vehicle body or flows through the space between the vehicle body and the ground as shown in FIG. 1.

만약, 차량이 고속 주행을 하게 되면 차체의 상부곡면을 타고 흘러가는 바람은 차체를 지면쪽으로 낮추려는 압력(도 1에 도시된 화살표 F1)을 발생시키고, 반대로 또는 차체와 지면사이의 공간을 통해 흘러가는 바람은 차체를 지면쪽으로 상승시키려는 압력(도 1에 도시된 화살표 F2)을 발생시키게 된다.If the vehicle is traveling at high speed, the wind flowing on the upper curved surface of the vehicle generates pressure (arrow F1 shown in FIG. 1) to lower the vehicle body to the ground, and vice versa or flows through the space between the vehicle body and the ground. The wind will generate pressure (arrow F2 shown in FIG. 1) to raise the vehicle body to the ground.

이때, 차체에 발생되는 압력의 크기는 F1 ≪ F2 이 보통이며, 이에 따라 고속 주행중인 차량은 타이어의 접지력이 감소되면서 자세가 불안정해지게 되고, 결국에는 주행안정성을 확보하지 못함으로써 대형사고를 일으키게 되는 문제점이 있었다.At this time, the magnitude of the pressure generated in the vehicle body is usually F1 ≪ F2. Accordingly, a vehicle that is traveling at a high speed may have a bad posture due to a reduction in tire grip, and thus may cause a large accident by failing to secure driving stability. There was a problem.

따라서, 상기와 같은 문제점을 해소하기 위해 많은 연구가 지속적으로 이루어져 왔으며, 이에 대한 결과로 근래에 생산되는 모든 차량에는 차량의 주행속도에 따라 차고의 높이를 조절하는 차고조정장치를 기본적으로 장착하고 있는 실정이다.Therefore, many studies have been continuously conducted to solve the above problems, and as a result, all vehicles produced recently have basically equipped with a garage adjustment device for adjusting the height of the garage according to the traveling speed of the vehicle. It is true.

즉, 요즘 차량에 장착되는 차고조정장치는 대부분 유압이나 공기압을 이용하여 차체의 높낮이를 조절할 수 있도록 되어 있으며, 보통 운전석에 구비된 차고조정스위치를 운전자가 조작하게 되면 차고조정스위치의 신호를 전달받은 전자제어유니트(ECU)가 전자제어현가장치(ECS)의 작동부를 제어하게 됨으로써 주행중인 차량의 차고가 주행속도에 따라 자동적으로 조정되게 되는 것이다.In other words, most of the height adjustment device mounted on a vehicle is able to adjust the height of the vehicle body by using hydraulic pressure or air pressure, and when the driver operates the height adjustment switch provided in the driver's seat, the signal of the height adjustment switch is received. The electronic control unit ECU controls the operation of the electronic control suspension ECS so that the height of the vehicle being driven is automatically adjusted according to the traveling speed.

그러나, 상기와 같은 종래의 차고조정장치는 제반 부품들의 원가가 비교적 고가의 부품들(유압 액츄에이터, 공기스프링 등)을 많이 사용하게 됨으로써 제조원가가 상승되는 문제점이 있을 뿐만 아니라, 차량의 전체중량을 증대시키는 원인이 되어 연비향상에도 악영향을 주는 문제점이 있었다.However, the conventional garage adjustment apparatus as described above has a problem in that manufacturing costs are increased by using a lot of relatively expensive components (hydraulic actuators, air springs, etc.), and increase the overall weight of the vehicle. There was a problem that causes the adverse effects on fuel economy improvement.

이에 본 발명은 상기한 같은 문제점을 해소하기 위해 안출된 것으로, 차량의 주행속도에 따라 차고를 자동적으로 조정시킬 수 있는 장치를 구성함에 있어 제조원가를 최대한 절감시키고 아울러 차량의 중량증대를 최대한 억제시킴으로써 연비향상에도 도움을 줄 수 있도록 된 차고조정장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in order to solve the above problems, in the configuration of a device that can automatically adjust the garage according to the running speed of the vehicle to reduce the manufacturing cost as much as possible and to suppress the increase in weight of the vehicle as much as possible Its purpose is to provide a garage adjustment that can also help improve.

상기와 같은 목적을 달성하기 위한 본 발명의 차고조정장치는, 일단이 서스펜션암의 상단에 고정되고 타단이 차륜과 인접한 차체의 밑면을 향하도록 설치되는 탄성부재와, 밑면은 상기 탄성부재의 선단에 고정되도록 결합되고 타단은 상기 차체의 밑면에 고정되도록 결합되며 내부에는 오일이 충진된 벨로즈형 용기부재와, 상기 차륜의 스핀들과 횡방향으로 연결되는 차체의 소정부위에 고정되도록 설치되는 유압실린더부재와, 상기 벨로즈형 용기부재와 유압실린더부재를 연통시키는 유압파이프부재와, 상기 유압실린더부재내에 리턴스프링을 매개로 탄력적인 직선왕복 이동이 가능하도록 설치되는 피스톤부재 및 피스톤로드부재와, 일단은 상기 피스톤로드부재에 연결되고 타단은 상기 스핀들을 관통하여 차륜에 형성된 회전공간내에 위치되도록 설치되는 와이어부재와, 상기 와이어부재의 선단에 결합되어 회전공간내에 위치되면서 차륜의 회전속도에 따라 발생하는 원심력을 이용해 회전운동을 하는 질량체부재로 구성되는 것을 특징으로 한다.Garage adjustment apparatus of the present invention for achieving the above object, the elastic member is installed so that one end is fixed to the upper end of the suspension arm and the other end toward the bottom of the vehicle body adjacent to the wheel, the bottom is at the tip of the elastic member It is coupled to be fixed and the other end is coupled to be fixed to the underside of the vehicle body, there is a bellows-type container member filled with oil, and the hydraulic cylinder member is installed to be fixed to a predetermined portion of the vehicle body connected in the transverse direction to the spindle of the wheel And, the hydraulic pipe member for communicating the bellows-type container member and the hydraulic cylinder member, the piston member and the piston rod member is installed in the hydraulic cylinder member to enable the elastic straight reciprocating movement via the return spring, and one end The other end is connected to the piston rod member so that the other end is located in the rotating space formed in the wheel through the spindle It is characterized in that it is composed of a mass member for the rotational movement using a centrifugal force generated in accordance with the rotational speed of the wheel while being located in the rotation space coupled to the wire member and the front end of the wire member.

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

도 2는 본 발명에 따른 차고조정장치를 설명하기 위한 개략적인 개념도로서, 본 발명에 따른 차고조정장치는 일단이 서스펜션암(1)의 상단에 고정되고 타단이 차륜(2)과 인접한 차체(3)의 밑면을 향하도록 설치되는 탄성부재(4)와, 밑면은 상기 탄성부재(4)의 선단에 고정되도록 결합되고 타단은 상기 차체(3)의 밑면에 고정되도록 결합되며 내부에는 오일(5)이 충진된 벨로즈형 용기부재(6)와, 상기 차륜(2)의 스핀들(7)과 횡방향으로 연결되는 차체의 소정부위에 고정되도록 설치되는 유압실린더부재(8)와, 상기 벨로즈형 용기부재(6)와 유압실린더부재(8)를 연통시키는 유압파이프부재(9)와, 상기 유압실린더부재(8)내에 리턴스프링(11)을 매개로 탄력적인 직선왕복 이동이 가능하도록 설치되는 피스톤부재(12) 및 피스톤로드부재(13)와, 일단은 상기 피스톤로드부재(13)에 연결되고 타단은 상기 스핀들(7)을 관통하여 차륜(2)에 형성된 회전공간(2a)내에 위치되도록 설치되는 와이어부재(14)와, 상기 와이어부재(14)의 선단에 결합되어 회전공간(2a)내에 위치되면서 차륜(2)의 회전속도에 따라 발생하는 원심력을 이용해 회전운동을 하는 질량체부재(15)로 구성된다.FIG. 2 is a schematic conceptual view illustrating a garage adjustment apparatus according to the present invention. The garage adjustment apparatus according to the present invention has one end fixed to an upper end of the suspension arm 1 and the other end of the vehicle body 3 adjacent to the wheel 2. The elastic member 4 is installed to face the bottom of the), the bottom is coupled to be fixed to the front end of the elastic member 4, the other end is coupled to be fixed to the bottom of the vehicle body 3 and the oil (5) inside The filled bellows-type container member 6, the hydraulic cylinder member 8 which is installed to be fixed to a predetermined portion of the vehicle body connected in the transverse direction to the spindle 7 of the wheel 2, and the bellows type A hydraulic pipe member 9 for communicating the container member 6 and the hydraulic cylinder member 8 and a piston installed in the hydraulic cylinder member 8 so as to enable elastic straight reciprocating movement via a return spring 11. The member 12 and the piston rod member 13 and one end of the piston rod A wire member 14 connected to the ash 13 and installed at the other end so as to be positioned in the rotation space 2a formed in the wheel 2 through the spindle 7 and coupled to the tip of the wire member 14. It is located in the rotating space (2a) is composed of a mass body member 15 for the rotary motion using the centrifugal force generated according to the rotational speed of the wheel (2).

여기서, 상기 질량체부재(15)의 회전반경(R)은 차륜(2)의 회전속도가 증가할수록 커지고, 반대로 차륜(2)의 회전속도가 감소할수록 작아지게 되는데, 그 이유는 전술한 바와 같이 질량체부재(15)의 원심력에 기인한다.Here, the rotation radius (R) of the mass member 15 becomes larger as the rotational speed of the wheel (2) increases, on the contrary, becomes smaller as the rotational speed of the wheel (2) decreases, because the mass body as described above This is due to the centrifugal force of the member 15.

그리고, 상기 벨로즈형 용기부재(6)의 체적은 질량체부재(15)의 회전반경(R)이 커질수록 유압실린더부재(8)쪽으로 이동하는 오일(5)의 양만큼 감소되고, 상기 질량체부재(15)의 회전반경(R)이 작아질수록 유압실린더부재(8)로부터 배출되는 오일(5)의 양만큼 증가되면서, 차고의 증감이 이루어지게 된다.In addition, the volume of the bellows-type container member 6 is reduced by the amount of oil 5 moving toward the hydraulic cylinder member 8 as the rotation radius R of the mass body member 15 increases, and the mass body member As the rotation radius R of 15 decreases as the amount of oil 5 discharged from the hydraulic cylinder member 8 increases and decreases the height of the garage.

또한, 상기 회전공간(2a)은 질량체부재(15)가 최대의 회전반경(R)을 갖더라도 서로 접촉되지 않는 크기로 형성되는 구조로 되어 있다.In addition, the rotation space (2a) has a structure that is formed in a size that does not contact each other even if the mass member 15 has the maximum rotation radius (R).

이하, 본 발명에 따른 차고조정장치의 작동과정에 대해 도 2와 도 3을 참조로 상세히 설명한다.Hereinafter, an operation process of the garage adjustment apparatus according to the present invention will be described in detail with reference to FIGS. 2 and 3.

먼저, 도 2에 도시된 상태는 차량이 중속 이하(보통 60㎞/h 이하)로 주행을 하고 있는 상태로서, 이때에는 차륜(2)의 회전속도가 크지 않음으로 인해 질량체부재(15)의 회전반경(R)도 비교적 작은 반경을 가지면서 회전을 하게 된다.First, the state shown in FIG. 2 is a state in which the vehicle is traveling at a medium speed or less (usually 60 km / h or less), and at this time, the mass body member 15 is rotated because the rotation speed of the wheel 2 is not large. Radius R also rotates with a relatively small radius.

그리고, 질량체부재(15)의 회전반경(R)이 작은 크기로서 회전을 하게 되면, 차륜(2)쪽으로 이동되는 와이어부재(14)의 이동량도 작아지게 되고, 아울러 피스톤로드부재(13) 및 피스톤부재(12)가 유압실린더부재(8)로부터 인출되는 길이도 작아지게 된다.Then, when the rotation radius (R) of the mass member 15 is rotated to a small size, the amount of movement of the wire member 14 moved toward the wheel 2 also becomes smaller, and at the same time the piston rod member 13 and the piston The length with which the member 12 is drawn out from the hydraulic cylinder member 8 also becomes small.

또한, 피스톤로드부재(13) 및 피스톤부재(12)의 인출길이가 작으면, 벨로즈형 용기부재(6)내에 충진된 오일(5)이 유압파이프부재(9)를 통해 유압실린더부재(8)쪽으로 이동되는 양도 작아지게 되고, 이로 인해 상기 벨로즈형 용기부재(6)의 체적이 작아지는 변화가 거의 미비하게 됨으로써 차고의 변화에도 큰 영향을 미치지 않게 된다.In addition, when the withdrawal lengths of the piston rod member 13 and the piston member 12 are small, the oil 5 filled in the bellows-type container member 6 is transferred to the hydraulic cylinder member 8 through the hydraulic pipe member 9. The amount moved to the side also becomes small, and thus the change in the volume of the bellows-shaped container member 6 becomes almost insignificant, thereby not having a great influence on the change of the garage.

이상태에서, 운전자가 가속페달을 답력을 증가시키게 되면 차량은 점차적으로 고속주행(보통 60㎞/h 이상) 상태에 이르게 되고, 이때 질량체부재(15)의 회전반경(R)은 차륜(2)의 회전속도에 비례하는 만큼 도 3에 도시된 바와 같이 점차적으로 증가하게 된다.In this state, when the driver increases the pedal effort of the accelerator pedal, the vehicle gradually reaches a high speed driving (usually 60 km / h or more), and the rotation radius R of the mass member 15 is determined by As it is proportional to the rotation speed, it gradually increases as shown in FIG. 3.

그리고, 질량체부재(15)의 회전반경(R)이 커지게 되면, 차륜(2)쪽으로 이동되는 와이어부재(14)의 이동량이 커지면서 피스톤로드부재(13) 및 피스톤부재(12)가 유압실린더부재(8)로부터 인출되는 길이도 커지게 되고, 이에 따라 벨로즈형 용기부재(6)내에 충진된 오일(5)이 유압파이프부재(9)를 통해 유압실린더부재(8)쪽으로 이동되는 양도 많아지게 된다.Then, when the rotation radius (R) of the mass body member 15 increases, the amount of movement of the wire member 14 moved toward the wheel 2 increases while the piston rod member 13 and the piston member 12 are hydraulic cylinder members. The length of the lead drawn out from (8) is also increased, so that the amount of oil (5) filled in the bellows-type container member (6) is moved toward the hydraulic cylinder member (8) through the hydraulic pipe member (9). do.

또한, 많은 양의 오일(5)이 벨로즈형 용기부재(6)에서 유압실린더부재(8)쪽으로 이동되면, 벨로즈형 용기부재(6)의 체적감소 변화가 대폭적으로 이루어지게 되고, 이로 인해 차고가 낮아지는 변화가 발생되게 된다.In addition, when a large amount of oil (5) is moved from the bellows-type container member (6) toward the hydraulic cylinder member (8), the volume change of the bellows-type container member (6) is made largely, thereby Changes in garage height will occur.

이와 같이, 고속주행시 차고가 자동적으로 낮아지게 되면 차륜(2)의 접지력이 증대됨으로써 주행안정성과 선회안정성을 확보할 수 있게 되고, 아울러 안전운행에도 큰 도움이 되는 잇점이 있게 된다.As such, when the garage is automatically lowered during high-speed driving, the traction force of the wheel 2 is increased, thereby ensuring driving stability and turning stability, and also having a great advantage in safe driving.

한편, 차량의 주행속도가 고속에서 다시 중속이하로 변화되면, 질량체부재(15)의 회전반경(R)이 다시 작아지게 되고 또한 유압실린더부재(8)로부터 인출되었던 피스톤로드부재(13) 및 피스톤부재(12)도 리턴스프링(11)의 복원력에 의해 다시 삽입되게 되며, 이로 인해 유압실린더부재(8)쪽으로 이동되었던 오일(5)도 유압파이프부재(9)를 통해 벨로즈형 용기부재(6)쪽으로 이동되게 된다.On the other hand, when the running speed of the vehicle changes from the high speed to below the medium speed again, the rotation radius R of the mass member 15 becomes smaller again, and the piston rod member 13 and the piston drawn out from the hydraulic cylinder member 8 are reduced. The member 12 is also reinserted by the restoring force of the return spring 11, so that the oil 5, which has been moved to the hydraulic cylinder member 8, is also closed through the hydraulic pipe member 9. Will be moved to).

이에 따라, 상기 벨로즈형 용기부재(6)의 체적은 오일(5)의 압력에 의해 점차적으로 증가되어 도 2에 도시된 상태를 유지하면서 다음번의 차고변화 작동에 대비하게 된다.Accordingly, the volume of the bellows-type container member 6 is gradually increased by the pressure of the oil 5 to prepare for the next garage change operation while maintaining the state shown in FIG.

이와 같이, 본 발명에 따른 차고조정장치는 차량의 주행속도에 따라 차고의 높낮이를 자동적으로 조절시킬 수 있게 됨으로써, 주행속도에 상관없이 항상 차량의 주행안정성과 선회안정성을 확보할 수 있게 되고, 이로 인해 안전운행에도 큰 도움을 줄 수 있게 되어 차량에 대한 소비자의 선호도를 증대시킬 수 있는 잇점이 있게 된다.As such, the height adjusting apparatus according to the present invention can automatically adjust the height of the garage according to the traveling speed of the vehicle, thereby ensuring the driving stability and the turning stability of the vehicle at all times regardless of the driving speed. As a result, it can be a great help for safe driving, which increases the consumer's preference for the vehicle.

또한, 본 발명의 차고조정장치는 전자제어유니트(ECU)와 전자제어현가장치(ECS)를 이용하여 작동하는 현상태의 차고조정장치보다, 제반 부품들의 원가 및 부품수를 감소시킬 수 있게 됨으로써 제조원가를 절감시킬 수 있게 되고, 아울러 차량의 전체중량을 감소시킬 수 있게 됨으로써 차량의 연비향상에도 도움을 줄 수 있는 잇점이 있게 된다.In addition, the garage adjustment apparatus of the present invention can reduce the production cost and the number of parts of the components than the garage adjustment apparatus of the present state using the electronic control unit (ECU) and the electronic control suspension (ECS). It is possible to reduce, and also to reduce the overall weight of the vehicle has the advantage that can help to improve the fuel economy of the vehicle.

이상 설명한 바와 같이 본 발명에 의한 차고조정장치는, 주행속도에 따라 차고의 높낮이가 자동적으로 조절되어 차량의 주행안정성과 선회안정성이 확보되고, 비교적 적은 부품수와 적은 제조원가를 통해 구성됨으로써 차량에 대한 소비자의 선호도가 증대되게 되며, 아울러 차량의 전체중량을 감소시킬 수 있게 됨으로써 연비향상에도 도움이 되는 효과가 있게 된다.As described above, the height adjustment apparatus according to the present invention, the height of the garage is automatically adjusted according to the traveling speed to ensure the driving stability and turning stability of the vehicle, it is configured through a relatively small number of parts and a small manufacturing cost for the vehicle Consumer preferences are increased, and the overall weight of the vehicle can be reduced, thereby improving fuel efficiency.
