According to the present invention, as shown in FIGS. 2 to 3, liquid crystal engine mountings 22 and 24 are installed at both ends of the engine 20 or the transmission 18 so that the front liquid crystal engine mounting 22 and the rear liquid crystal engine mounting are provided. A hydraulic pipe 26 is connected between the 24 and the front dampers 28, respectively, and when the front part of the vehicle sinks during sudden braking, the fluid of the front damper 28 passes through the hydraulic pipe 26 to the front liquid crystal engine mounting 22 ) To improve the elasticity of the front liquid crystal engine mounting, thereby reducing the engine shake of the car and reducing the impact sound, thereby improving the riding comfort of the driver and passenger in the car.

Hydro roll rod

본 발명은 롤로드에 관한 것으로, 보다 상세하게는 유체를 포함하는 액실을 통하여 차량에서 발생하는 저주파 대변위 거동을 단시간에 감쇄시켜 차체로의 진동전달을 최소화시키고, 더불어 차량의 NVH(Noise Vibration Harshness)성능도 향상시킬 수 있도록 하는 하이드로 롤로드에 관한 것이다. More particularly, the present invention relates to a roll load, and more particularly, to a vibration damping device capable of minimizing transmission of vibration to a vehicle body by attenuating low-frequency and large-displacement behavior occurring in a vehicle through a liquid chamber including a fluid in a short period of time, ) Performance of the hydraulic roll. 상기와 같은 본 발명은, 상기 롤로드에 전달되는 진동을 유체가 흡수할 수 있기 때문에 차량에 전달되는 진동을 감소시킬 수 있고, 상기 리어 인슐레이터의 피로를 줄여 내구성을 향상시킬 수 있으므로 매우 경제적이다. 또한, 2개의 리어 인슐레이터 내부의 액실 사이를 연결하는 유체 통로를 형성하여 하나의 액실로부터 다른 액실로 유체가 자유로이 이동할 수 있으므로 하나의 리어 인슐레이터에 가해지는 진동 및 압력을 다른 리어 인슐레이터와 분산하여 받을 수 있어 보다 향상된 진동 감쇄 효과를 얻을 수 있다. The present invention as described above can reduce the vibration transmitted to the vehicle because the fluid can absorb the vibration transmitted to the roll rod, and the fatigue of the rear insulator can be reduced to improve the durability, which is very economical. In addition, the fluid passages connecting the liquid chambers inside the two rear insulators are formed so that the fluid can freely move from one liquid chamber to the other liquid chamber, so that vibration and pressure applied to one rear insulator are dispersedly received by the other rear insulator So that it is possible to obtain an improved vibration damping effect. 롤로드, 액실, 하이드로 Roll rod, liquid chamber, hydro
