Description

스패어 타이어를 이용한 차량의 진동 저감 구조{A vibration reducing structure by using spare tire}A vibration reducing structure by using spare tires

본 발명은 차량 엔진의 아이들 동작시 차량에 탑재되어 있는 스패어 타이어를 이용하여 엔진에서 발생된 진동의 역위상을 갖는 진동을 인가할 수 있도록 하여 차량이 아이들 동작시에도 차량의 진동을 저감할 수 있도록 한 스패어 타이어를 이용한 차량의 진동 저감 구조에 관한 것이다. The present invention can apply the vibration having the reverse phase of the vibration generated from the engine by using the spare tire mounted on the vehicle during the idle operation of the vehicle engine to reduce the vibration of the vehicle even during the idle operation of the vehicle. The present invention relates to a vibration reduction structure of a vehicle using spare tires.

차량 엔진의 아이들(idle) 동작시 차량의 운전자 및 탑승자가 차체 및 스티어링 휠을 통해 느끼는 진동은 엔진의 폭발력에 의해 발생된 진동이 전해지기 때문이다. The vibration felt by the driver and the passenger of the vehicle through the vehicle body and the steering wheel during the idle operation of the vehicle engine is because the vibration generated by the explosion force of the engine is transmitted.

차량의 엔진이 고속으로 회전하는 경우에는 엔진에서 발생된 진동이 서로 감쇄시키는 역할을 하기 때문에 운전자 또는 탑승자가 느끼는 진동은 적게된다.When the engine of the vehicle rotates at a high speed, vibrations generated by the engine serve to attenuate each other, thereby reducing vibrations felt by the driver or the passenger.

그러나, 차량의 엔진을 아이들(idle) 동작시키는 경우, 엔진의 폭발 간격이 서로 멀기 때문에 진동을 서로 감쇄시켜주지 못하고 전달되기 때문에 승차감이 저하되는 문제점이 있었다. However, when operating the engine of the vehicle (idle), there is a problem that the ride comfort is reduced because the explosion interval of the engine is far apart so that the vibrations are not attenuated each other.

도 1은 종래의 기술에 의한 차량 진동 저감 장치의 설치 상태를 나타내는 도면으로서, 엔진(1)의 아이들 동작시 진동을 저하시키기 위해 차량의 공진 모드와 역위상을 갖는 진동이 발생되는 엔진 마운트(2)를 설치하였다. 그러나, 차량의 엔진은 아이들 동작을 하는 경우도 있지만 차량이 다양한 속도로 주행하도록 하기 위해 서로 다른 회전수로 동작하는 경우가 대부분이기 때문에 역위상 발생 정도는 한계가 있다.1 is a view showing the installation state of a vehicle vibration reduction device according to the prior art, the engine mount (2) in which vibrations having a resonant mode and a reverse phase of the vehicle is generated in order to reduce vibrations during idle operation of the engine (1) ) Was installed. However, although the engine of the vehicle may be idle, in many cases, the reverse phase is limited because the vehicle is operated at different rotational speeds in order to drive the vehicle at various speeds.

이러한 한계를 극복하기 위하여 차량의 라디에이터 부쉬(3)를 이용하여 진동이 상쇄도록 하는 기술이 개시되었다. In order to overcome this limitation, a technique is disclosed in which a vibration is canceled by using a radiator bush 3 of a vehicle.

그러나 차량의 라디에이터는 엔진 동작중 발생되는 열을 냉각시키기 위한 구성요소이므로 엔진의 동작 상태에 따라 자체 온도가 다양하게 변화되고 이에 따라 진동 특성이 변화하기 때문에 진동 특성을 전체 온도가 아닌 특정 온도 범위로 설정할 수 밖에 없었고, 이에 따라 진동 감쇄 효과는 미미했다.However, since the radiator of the vehicle is a component for cooling the heat generated during engine operation, its own temperature varies according to the operating state of the engine and the vibration characteristic changes accordingly, so the vibration characteristic is not controlled to a specific temperature range. There was no choice but to set the vibration damping effect.

또한, 차량의 주행시 차체 및 스티어링 휠의 진동을 방지하기 위한 현가 장치의 튜닝은 운전성에 많은 영향을 주기 때문에, 현가 장치의 개량에 한계가 있는 문제점이 있었다. In addition, since the tuning of the suspension device to prevent the vibration of the vehicle body and the steering wheel when driving the vehicle has a lot of influence on the driving performance, there is a problem that there is a limit to the improvement of the suspension device.

본 발명은 상기와 같은 문제점을 해결하고자 창안된 것으로서, 차량 엔진의 아이들 동작 또는 차량의 주행시 차체 및 스티어링 휠 진동을 제어함에 있어 차량에 탑재되어 있는 스패어 타이어를 이용하여 차체 진동의 위상과 역위상을 갖는 진동을 발생시켜 서로의 진동에 의해 진동이 감쇄되도록 하는 스패어 타이어를 이용한 차량의 진동 저감 구조를 제공하는 것을 목적으로 한다.The present invention has been made to solve the above problems, the phase and reverse phase of the vehicle body vibration using the spare tire mounted on the vehicle in controlling the vehicle body and steering wheel vibration during the idle operation of the vehicle engine or driving of the vehicle It is an object of the present invention to provide a vibration reduction structure of a vehicle using a spare tire that generates vibrations having a vibration so that the vibrations are attenuated by each other's vibrations.

도 2는 본 발명에 의한 스패어 타이어를 이용한 차량의 진동 저감 구조의 구성을 나타내는 도면이고, 도 3은 도 2의 A 부분의 상세도면으로서, 엔진(1)의 동작중 발생하는 진동을 감쇄하는 엔진 마운트(2)와 라디에이터 부쉬(3)가 설치되어 있는 차량에 있어서, 차량에서 발생되는 차체 진동을 측정하고 측정된 양에 해당하는 신호를 출력하는 진동 측정기(10), 상기 진동 측정기(10)에서 출력되는 신호를 입력받은 후 입력된 신호와 역위상을 갖는 진동이 발생되도록 제어 신호를 출력하는 제어부(20), 상기 제어부(20)에서 출력되는 제어 신호에 의해 스패어 타이어(5)를 상하로 진동시키는 액츄에이터(30)로 구성되어 있음을 도시하고 있다.2 is a view showing the configuration of a vibration reduction structure of a vehicle using a spare tire according to the present invention, Figure 3 is a detailed view of the portion A of Figure 2, attenuated vibration generated during operation of the engine 1 In a vehicle provided with an engine mount (2) and a radiator bush (3), a vibration measuring device (10) for measuring the body vibration generated in the vehicle and outputting a signal corresponding to the measured amount, the vibration measuring device (10) After receiving the signal output from the control unit 20 for outputting a control signal to generate a vibration having a reverse phase with the input signal, the spare tire (5) up and down by the control signal output from the control unit 20 It shows that it is composed of an actuator 30 to vibrate.

상기 스패어 타이어(5)의 고정축(6) 부위에는 코일 스프링(40)이 추가로 설치되는 것이 바람직하다. Preferably, the coil spring 40 is additionally installed at the fixed shaft 6 portion of the spare tire 5.

상기와 같이 구성된 본 발명의 실시예를 도면을 참조하여 설명하면 다음과 같다.When explaining the embodiment of the present invention configured as described above with reference to the drawings as follows.

차량의 주행 중 또는 차량 엔진의 아이들 동작시 발생되는 진동은 진동 측정기(10)에 의해 측정되고, 진동 측정기(10)는 측정된 진동량에 해당하는 신호를 출력하여 제어부(20)로 입력되도록 한다. Vibration generated during driving of the vehicle or during idle operation of the vehicle engine is measured by the vibration measuring device 10, and the vibration measuring device 10 outputs a signal corresponding to the measured vibration amount to be input to the controller 20. .

제어부(20)는 입력되는 신호에 의해 현재 차체에 인가되는 진동의 양과 위상을 판정하도록 하고, 제어부(20)는 판정된 진동의 양과 진동의 위상을 감쇄시키기 위해 진동 측정기(10)에서 측정된 진동의 양과 동일하고 위상이 서로 반대인 진동을 발생시킬 수 있도록 제어 신호를 출력한다. The control unit 20 determines the amount and phase of the vibration currently applied to the vehicle body by the input signal, and the control unit 20 measures the vibration measured by the vibration measuring device 10 to attenuate the determined amount and phase of the vibration. The control signal is output to generate vibrations that are equal to the amount of and opposite to each other.

제어부(20)에서 출력되는 제어 신호는 액츄에이터(30)로 입력되어 액츄에이터(30)가 동작하도록 한다. 액츄에이터(30)는 입력되는 제어 신호에 따라 차량의 트렁크 하부에 설치되어 있는 스패어 타이어(5)를 상하로 동작시키도록 한다.The control signal output from the control unit 20 is input to the actuator 30 to operate the actuator 30. The actuator 30 operates the spare tire 5 installed below the trunk of the vehicle up and down according to the input control signal.

이때 스패어 타이어(5)의 상하 동작이 원활히 되도록 스패어 타이어(5)의 고정축(6) 상에는 코일 스프링(40)이 설치되는 것이 바람직하다. At this time, the coil spring 40 is preferably provided on the fixed shaft 6 of the spare tire 5 so that the vertical operation of the spare tire 5 is smooth.

스패어 타이어(5)를 이용하여 발생된 진동은 차량의 엔진 동작 중 발생하는 진동과 서로 역방향의 위상을 갖고 있으므로, 진동은 서로 상쇄되어 운전자와 탑승자는 진동을 느끼지 못하게 된다. Since the vibration generated using the spare tire 5 has a phase opposite to that generated during engine operation of the vehicle, the vibrations cancel each other so that the driver and the passenger do not feel the vibration.
