본 발명은 차량의 현가장치를 구성하는 토오션 바아 스프링에 관한 것으로, 특히 차량의 주행상태에 따라 토오션 바아 스프링의 길이를 변환시키거나 비틀림량을 조절하여 승차감과 선회 및 주행 안정성을 향상시킬 수 있도록 된 토오션 바아 스프링의 스프링상수 가변장치에 관한 것이다.The present invention relates to a torsion bar spring constituting a suspension device of a vehicle, and in particular, by changing the length of the torsion bar spring or adjusting the amount of torsion according to the driving state of the vehicle, it is possible to improve ride comfort, turning and running stability. It relates to a spring constant variable device of the torsion bar spring.
일반적으로 자동차의 현가장치는 차축과 차체를 연결하여 주행중에 차축이 노면으로부터 받는 진동이나 충격을 차체에 직접적으로 전달되지 않도록 제어하여 차체와 화물의 손상을 방지하고 승차감을 좋게 만드는 장치로서, 노면으로부터 충격을 완화시키는 섀시 스프링과, 섀시 스프링의 자유진동을 제어하여 승차감을 좋게 하는 쇽 업소버 및 차량의 롤링을 방지하는 스태빌라이저 등으로 구성된다.In general, the suspension system of a car connects the axle and the body so that the vibrations or shocks received from the road surface are not directly transmitted to the body while driving, thereby preventing damage to the body and cargo and improving ride comfort. It includes a chassis spring for mitigating impact, a shock absorber for controlling the free vibration of the chassis spring to improve ride comfort, and a stabilizer for preventing rolling of the vehicle.
여기서 상기 섀시스프링은 차체와 바퀴사이에 설치되어 자동차가 주행할 때에 노면에서 받는 충격과 바퀴의 진동을 흡수하여 차체에 전달하지 않기 위한 것으로서, 금속제의 리이프 스프링과, 코일 스프링, 토오션 바아 스프링 등이 있고, 그외에도 고무 스프링이나 공기 스프링 등도 사용되고 있다.Here, the chassis spring is installed between the vehicle body and the wheels so as to absorb shocks and vibrations of the wheels when the vehicle is driven and not transmit them to the vehicle body. The metal springs, coil springs and torsion bar springs are made of metal. And the like, and rubber springs and air springs are also used.
도 1은 상기한 종래의 토오션바아 스프링을 사용한 더블 위시본형 현가장치를 도시한 것인 바, 즉 너클(101)에 체결된 어퍼 아암(102)에 토오션 바아 스프링(103)의 일단이 체결되고, 상기 토오션 바아 스프링(103)의 타단은 앵커아암(104)을 매개로 차체에 체결되며, 상기 너클에는 어퍼 아암과 소정 간격을 두고 로어 아암(105)이 체결되면서 이 로어 아암에는 쇽 업소버(106)가 장착되어 있는 한편, 상기 좌측 및 우측의 로어아암은 스테빌라이저 바아(107)을 매개로 서 로 연결되어 있다.1 illustrates a double wishbone suspension using a conventional torsion bar spring as described above, that is, one end of the
여기서 상기 토오션 바아 스프링(103)은 어퍼 아암에 체결되어 어퍼 아암에 전달되는 진동 및 충격을 완충시키는 역할을 하는 것으로서, 소정의 프리텐션이 가해진 상태로 차체에 체결되는 바, 이러한 토오션 바아 스프링의 스프링상수는 토오션 바아의 직경에 비례하는 반면에 길이에는 반비례하게 되어 있다.In this case, the
그런데 상기와 같은 종래의 토오션 바아 스프링은 일정한 길이와 직경을 갖고서 차체와 어퍼 아암사이에 장착되어 있으므로, 스프링상수를 가변시킬 수 없었고, 이 때문에 차량의 주행중에 여러 형태로 전달되는 진동 및 충격에 효과적으로 대응할 수 없다고 하는 결점이 있었다.However, since the conventional torsion bar spring is mounted between the vehicle body and the upper arm with a constant length and diameter, the spring constant cannot be changed, and therefore, the vibration and shock transmitted in various forms while the vehicle is running. There was a flaw that it could not respond effectively.
이에 본 발명은 상기한 결점을 해소하기 위해 안출된 것으로, 토오션 바아의 길이와 비틀림량을 차량의 주행상태에 따라 적절히 가변시켜 노면을 통해 전달되어 오는 진동 및 충격에 능동적으로 대처해서 승차감과 주행 안정성 및 선회 안정성을 향상시킬 수 있도록 한 토오션 바아 스프링의 스프링상수 가변장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and the length and torsion amount of the torsion bar are appropriately changed according to the driving state of the vehicle to actively cope with the vibration and shock transmitted through the road surface, so that the riding comfort and driving It is an object of the present invention to provide a spring constant variable device of a torsion bar spring to improve stability and turning stability.
상기한 바의 목적을 달성하기 위한 본 발명은, 어퍼 아암에 일단이 축방향이동은 가능하나 상대회전은 불가능하도록 세레이션 결합된 좌측 및 우측 토오션 바아 스프링과;

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 발명의 1실시예에 따른 스프링상수 가변장치가 장착된 토오션 바아 스프링의 장착 상태도인 바, 즉 좌륜 및 우륜의 너클에 체결되는 어퍼 아암(1)에는 토오션 바아 스프링(2)의 일단이 축방향으로 이동가능한 동시에 회전은 불가능하도록 세레이션으로 체결되고, 상기 각 토오션 바아 스프링(2)의 타단에는 앵커 아암(3)이 일단이 일체로 부착되며, 상기 각 앵커 아암(3)의 타단에는 차체의 폭방 향으로 배열된 로드(4)가 연결되어, 2개의 앵커아암이 상기 로드를 매개로 서로 연결되어 있다.FIG. 2 is a state diagram of a torsion bar spring equipped with a spring constant variable device according to an embodiment of the present invention, that is, a
그리고 상기 로드의 중앙부위에는 관통하는 구멍이 형성되면서 구멍의 내주면에는 나사부가 형성되고, 상기 관통구멍에 스크류(5)가 끼워져서 나사부를 매개로 체결되어 있는 한편, 상기 스크류(5)는 모우터에 의해 회전되도록 모우터(6)와 연결되어 있다.In addition, while the through hole is formed in the central portion of the rod, a screw portion is formed on the inner circumferential surface of the hole, and the
또 상기 모우터는 콘트롤러(ECU)로부터 동작전원을 공급받아 작동되게 콘트롤러의 출력단자에 연결되어 있고, 상기 콘트롤러의 입력단자에는 차고높이센서(7)와 차속센서(8) 및 운전자가 2개의 모드를 선택할 수 있는 모드 스위치(9)가 각각 연결되어 있다.In addition, the motor is connected to the output terminal of the controller to be operated by receiving operating power from the controller (ECU), the input terminal of the controller, the height of the height sensor (7), the vehicle speed sensor (8) and the driver to operate two modes
이에 따라 차량의 주행상태는 상기 차고센서와 차속센서에 의해 감지되어 콘트롤러로 입력되고, 콘트롤러는 입력된 감지신호로 차량의 주행상태를 판별하여 그에 상응하는 제어전류를 상기 모우터에 인가시키게 되고, 모우터는 인가된 동작전원으로 구동하여 상기 스크류를 시계방향 또는 반시계방향으로 회전시켜주게 되어, 이 스크류의 회전운동으로 상기 로드가 당겨지거나 밀려지면서 토오션 바아 스프링의 길이를 가변시키게 된다.Accordingly, the driving state of the vehicle is sensed by the height sensor and the vehicle speed sensor and input to the controller. The controller determines the driving state of the vehicle by the input detection signal and applies the corresponding control current to the motor. The motor is driven by an applied operating power source to rotate the screw clockwise or counterclockwise, and the length of the torsion bar spring is varied as the rod is pulled or pushed by the rotational movement of the screw.
상기와 같이 토오션 바아 스프링의 길이가 가변되면 토오션 바아 스프링의 스프링상수가 가변되어, 차량의 주행상태에 능적으로 대응해서 승차감과 주행안정성을 향상시키게 된다.As described above, when the length of the torsion bar spring is variable, the spring constant of the torsion bar spring is variable, so as to effectively correspond to the driving state of the vehicle, thereby improving the riding comfort and driving stability.
또 운전자가 상기 모드 스위치를 조작하여 모드를 선정하면, 상기 콘트롤러 가 선정된 모드를 감지하여 그에 상응하는 제어전류를 모우터에 인가시키게 되는 데, 운전자가 선정한 모드에 따라 콘트롤러가 모우터에 정방향 혹은 역방향으로 제어전류를 인가시켜 모우터의 회전방향으로 제어하게 된다.In addition, when the driver selects a mode by operating the mode switch, the controller detects the selected mode and applies a corresponding control current to the motor. The control current is applied in the reverse direction to control in the rotation direction of the motor.
즉 운전자가 모드 스위치를 조작하여 소프트 모드를 선정하게 되면, 콘트롤러가 이를 감지해서 소정시간동안에 제어전류를 모우터에 인가시키게 되고, 모우터는 전원을 공급받아 작동되면서 예컨대 스크류를 시계방향으로 회전시켜주게 되며, 이 스크류의 회전운동으로 상기 로드가 차체의 후방으로 이동되면서 토오션 바아 스프링을 밀어줌에 따라 토오션 바아 스프링의 전체 길이가 길어지면서 토오션 바아 스프링의 스프링상수가 작아지게 된다.That is, when the driver selects the soft mode by operating the mode switch, the controller detects this and applies the control current to the motor for a predetermined time. The motor is powered and operated, for example, to rotate the screw clockwise. As the rod is moved to the rear of the vehicle body by the rotational movement of the screw, the total length of the torsion bar spring becomes longer as the torsion bar spring is lengthened as the rod extends the torsion bar spring.
따라서 차량의 주행중에 작은 충격 등이 전달되어도 상기 토오션 바아 스프링이 적절히 흡수해 완충시켜주게 되므로, 차량의 승차감을 향상시킬수 있게 되는 것이다.Therefore, the torsion bar spring is properly absorbed and buffered even when a small shock or the like is transmitted while the vehicle is running, thereby improving the riding comfort of the vehicle.
한편 운전자가 모드 스위치를 조작하여 하드 모드를 선정하게 되면, 상기 콘트롤러가 모우터에 제어전류를 역방향으로 인가시키고, 이로 인해 상기 스크류는 반시계방향으로 회전되면서 로드를 차체의 전방으로 당겨줌에 따라 로드에 연결된 토오션 바아 스프링도 함께 당겨져서 그 전체 길이가 줄어들게 되어, 토오션 바아 스프링의 스프링상수가 크지게 된다.On the other hand, when the driver selects the hard mode by operating the mode switch, the controller applies the control current to the motor in the reverse direction, whereby the screw is rotated counterclockwise to pull the rod toward the front of the vehicle body. The torsion bar springs connected to the rods are also pulled together, reducing their overall length, which increases the spring constant of the torsion bar springs.
따라서 하드 모드상태에서는 스프링상수가 커지게 되어, 차량의 주행안정성을 향상시킬 수 있게 되는 것이다.Therefore, in the hard mode, the spring constant becomes large, thereby improving driving stability of the vehicle.
한편 도 3은 본 발명의 2실시예를 도시한 것인 바, 이 실시예에서는 토오션 바아 스프링의 비틀림량을 제어하기 위해 상기 로드(4)의 길이방향을 따라 대략 중앙부위가 2개로 분할되어 피스톤(10)을 매개로 일체로 연결되어 있고, 상기 피스톤(10)의 외주에는 피스톤을 감싸는 실린더(11)가 장착되며, 이 실린더에는 오일이 충전되어 있다.Meanwhile, FIG. 3 shows a second embodiment of the present invention. In this embodiment, in order to control the amount of torsion of the torsion bar spring, the center portion is divided into two parts along the longitudinal direction of the
또 상기 피스톤에 의해 구획지워진 실린더내부의 2개의 체임버에 오일을 공급하거나 드레인시키기 위해 오일펌프(12)가 연결되어 있고, 이 오일펌프는 콘트롤러(ECU)로부터 동작전원을 공급받아 작동하도록 콘트롤러의 출력단자에 연결되어 있으며, 상기 콘트롤러의 입력단자에는 차고센서(7)와 차속센서(8) 및 조향각센서(13)가 각각 연결되어 있다.In addition, an
이에 따라 차량의 선회시에 콘트롤러가 조향각센서를 매개로 차량의 조향방향을 감지하고, 콘트롤러는 조향방향에 따라 오일펌프에 제어전류를 인가시켜 좌측 토오션 바아 스프링이나 혹은 우측 토오션 바아 스프링을 시계방향이나 혹은 반시계방향으로 회전시켜서 비틀림량을 조절하여 차체를 안정되게 함으로써, 선회안정성과 승차감을 향상시킬 수 있게 되는 것이다.Accordingly, when the vehicle is turning, the controller detects the steering direction of the vehicle through the steering angle sensor, and the controller applies a control current to the oil pump according to the steering direction to watch the left torsion bar spring or the right torsion bar spring. It is possible to improve turning stability and ride comfort by adjusting the amount of torsion by rotating in the direction or counterclockwise to stabilize the vehicle body.
이상 설명한 바와 같이 본 발명에 따른 토오션 바아 스프링의 스프링상수 가변장치에 의하면, 차량의 주행중에 차고센서와 차속센서를 매개로 주행상태를 판별하여 그에 상응하는 제어전류를 모우터나 펌프에 인가시켜 토오션 바아 스프링의 길이를 변화시켜 스프링상수를 가변시키거나 혹은 토오션 바아 스프링의 비틀림량을 조절하여 차량의 주행상태에 능동적으로 대처해서 승차감과 주행안정성을 향상 시키고, 또 차량의 선회시에는 토오션 바아 스프링의 비틀림량을 조절하여 차체를 안정시켜 선회안정성을 향상시킬 수 있는 효과가 있다.As described above, according to the spring constant variable device of the torsion bar spring according to the present invention, the driving state is determined by using the height sensor and the vehicle speed sensor during driving of the vehicle, and the corresponding control current is applied to the motor or the pump. By varying the length of the ocean bar spring, the spring constant is varied or the amount of torsion of the torsion bar spring is adjusted to proactively cope with the driving conditions of the vehicle to improve ride comfort and driving stability. By adjusting the amount of torsion of the bar spring, the vehicle body is stabilized to improve turning stability.
