Description
본 발명은 차속에 감응하는 엔진마운팅 인슐레이터의 경도조정장치에 관한 것이다.The present invention relates to an apparatus for adjusting the hardness of an engine mounting insulator in response to a vehicle speed.
운전중의 엔진은 그 구조상 항상 진동이 생기게 되는 바 실린더수가 적은 엔진은 실린더수가 많은 것보다, 또 저속 회전시에는 고속 회전시보다 진동이 커지게 되며 이러한 엔진의 진동이 섀시나 바디에 전해져 승차감이 나빠지지 않도록 엔진 장착부에는 반드시 탄성체에 의한 방진장치가 설치되어 있다.The engine in operation always generates vibrations, and the engine with fewer cylinders has more vibration than the number of cylinders, and at low speeds, the vibrations are transmitted to the chassis or body. In order not to deteriorate, the engine mounting part is necessarily equipped with a dustproof device made of an elastic body.
통상 엔진의 마운팅에 있어서 고무재의 인슐레이터(Insulator)로서 엔진과 바디를 연결하여 인슐레이터의 압축, 인장, 비틀림 등의 작용에 따라 진동 및 소음을 흡수하도록 하고 있다.In general, in the mounting of an engine, an insulator of a rubber material is connected to an engine and a body to absorb vibrations and noises according to the action of compression, tension, and torsion of the insulator.
한편 인슐레이터는 차체의 진동이 심하게 나타나는 저속, 예를들면 아이들 구동시에는 차체진동 흡수효과를 높이도록 하기위해 유연한(Soft) 것이 좋으며 반대로 주행시에는 덜커덩거리는 것(Jerk)을 방지하기 위해 단단한(Hard) 것이 좋다.On the other hand, the insulator should be soft in order to increase the body vibration absorbing effect at low speed, for example, when the vibration of the body is severe, and hard in order to prevent jerking during driving. It is good.
그러나 종래의 경우 인슐레이터의 강성(Stiffness)이 항상 일정하므로서 차속에 따른 승차감 향상이 곤란하다는 문제점이 있다.However, in the related art, since the stiffness of the insulator is always constant, it is difficult to improve the riding comfort according to the vehicle speed.
이에 본 발명은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는바는 차속에 비례하여 저속에서는 인슐레이터의 경도를 유연하게 하며 고속운전시에는 단단하도록 가변적으로 조정하여 승차감을 향상시키게 되는 차속감응형 엔진마운팅 인슐레이터의 경도 조정장치를 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its purpose is to make the hardness of the insulator flexible at low speed in proportion to the speed of the vehicle, and to adjust the vehicle rigidly at high speed to improve the riding comfort. It is to provide a hardness adjustment device of the engine mounting insulator.

도 1 은 본 발명에 의한 엔진지지장치를 나타내는 도면이며 도 2 는 본 발명에 의한 인슐레이터 경도조정장치의 전체구성을 나타내는 도면이다.1 is a view showing an engine support apparatus according to the present invention, Figure 2 is a view showing the overall configuration of the insulator hardness adjustment apparatus according to the present invention.
도면중 부호 1은 엔진지지장치로서 엔진의 진동이 차체바디에 전달되는 것을 차단하기 위한 고무재의 인슐레이터(2)를 구비하고 있다.In the drawing, reference numeral 1 is an engine support device, and is provided with an insulator 2 made of rubber material for preventing the vibration of the engine from being transmitted to the body body.
상기 인슐레이터(2)의 몸체에는 빈 공간부(3)가 형성되며 그 공간부(3)에는 테이퍼로드(4)가 끼워지게 된다.An empty space 3 is formed in the body of the insulator 2, and the tapered rod 4 is fitted into the space 3.
상기 테이퍼로드(4)는 동력수단(5)에 의해 전진 및 후퇴하는 왕복직선운동을 하며 동력수단(5)은 스텝구동모터(6)와 래크(7)와 피니언(8) 등의 기구를 포함한다.The tapered rod 4 has a reciprocating linear motion that is advanced and retracted by the power means 5, and the power means 5 includes a mechanism such as a step driving motor 6, a rack 7, and a pinion 8. do.
상기 스텝구동모터(6)는 전자제어장치(9)의 제어에 따라 인가되는 펄스수만큼 정역구동되며 전자제어장치(9)는 차량속도센서(10)로부터 감지되는 차속이 낮아질 때에는 상기 테이퍼로드(4)가 공간부(3)로부터 후퇴하여 빠져 나오도록 스텝구동모터(6)를 제어하므로서 빈 공간부(3)만큼 인슐레이터(2)의 유연성을 증가시키게 되며, 차속이 상승시에는 이에 비례하여 상기 테이퍼로드(4)가 전진하여공간부(3)에 삽입되므로써 쐐기작용에 의해 인슐레이터(2)의 경도(Stiffness)를 증가시키도록 스텝구동모터(6)를 제어한다.The step driving motor 6 is driven forward and backward by the number of pulses applied according to the control of the electronic control device 9, and the electronic control device 9 has the tapered rod when the vehicle speed detected from the vehicle speed sensor 10 is lowered. By controlling the step driving motor 6 so that 4) retreats from the space part 3, the flexibility of the insulator 2 is increased by the empty space part 3, and when the vehicle speed rises, the taper is proportionally increased. As the rod 4 is advanced and inserted into the space 3, the step driving motor 6 is controlled to increase the stiffness of the insulator 2 by the wedge action.
이상과 같은 본 발명에 의하면 엔진의 진동을 흡수하는 고무재의 인슐레이터에 빈 공간부를 형성하고 차속에 비례하여 빈 공간부에 테이퍼로드를 삽입시켜 점차 단단해지도록 조정하는 것에 의해서 진동이 심한 저속에서는 인슐레이터의 유연성 증가로 진동소음의 감쇠효과가 증대되며 고속에서는 점차 인슐레이터의 경도를 증가시켜 단단하게 만들므로써 덜커덩거리는 차체 요동(Jerk)을 감소시켜 안락한 운행을 가능하게 하는 효과가 있다.According to the present invention as described above, the flexibility of the insulator is formed at low speed by severe vibration by forming an empty space portion in the rubber insulator absorbing the vibration of the engine and inserting a tapered rod into the empty space proportionately to the vehicle speed so as to be gradually hardened. The damping effect of vibration noise is increased by increasing, and at high speed, the hardness of the insulator is gradually increased to make it harder, thereby reducing the rattling of the car body (Jerk), thereby enabling comfortable driving.
