자동차의 트랜스미션 마운팅Transmission mounting of the car

본 고안은 트랜스미션을 차체에 장착하기 위한 트랜스미션 마운팅에 관한 것으로, 보다 구체적으로는 트랜스미션으로부터 발생되는 진동 및 소음이 차체로 전달되지 않도록 흡수, 저감시키는 자동차의 트랜스미션 마운팅에 관한 것이다.The present invention relates to a transmission mounting for mounting a transmission to a vehicle body, and more particularly to a transmission mounting of a vehicle to absorb and reduce the vibration and noise generated from the transmission to the vehicle body.

자동차의 트랜스미션은 엔진의 동력을 자동차의 주행 상태에 알맞도록 회전력과 속도를 바꾸어 구동 바퀴에 전달하는 장치로서, 클러치를 통해 엔진의 크랭크축과 직접적으로 연결된다. 따라서, 트랜스미션은 그 자신의 기계적인 구동 뿐만아니라, 엔진의 구동에 의한 영향으로 인하여 많음 진동과 소음이 발생된다.The transmission of the vehicle is a device that transmits the power of the engine to the driving wheels by changing the rotational force and speed to match the driving state of the vehicle, and is directly connected to the crankshaft of the engine through the clutch. Therefore, the transmission generates not only its own mechanical drive but also a lot of vibration and noise due to the influence of the engine driving.

따라서, 엔진과 마찬가지로 트랜스미션을 차체에 장착함에 있어서, 트랜스미션에서 발생되는 진동과 소음이 차체로 전달되어 승차감을 해치지 않도록 하는 것이 매우 중요하다.Therefore, as in the engine, it is very important to mount the transmission on the vehicle body so that vibrations and noise generated from the transmission are transmitted to the vehicle body so as not to impair the ride comfort.

이러한 트랜스미션을 차체에 장착하기 위한 트랜스미션 마운팅이 도 1에 도시되어 있다.Transmission mounting for mounting such a transmission to the vehicle body is shown in FIG. 1.

트랜스미션 마운팅은 각각 '

The dustproof rubber 3 is mounted between the inner fastener 1 and the outer fastener 2 having a cross section of a 'shape. A cavity is formed between the bottom of the upper plate of the outer bracket and the upper surface of the anti-vibration rubber.

상기와 같이 구성된 트랜스미션 마운팅은 외금구(2)가 트랜스미션(미도시)에 고정되고, 내금구(1)가 차체(미도시)에 고정되며, 트랜스미션으로부터 전달되는 진동 및 소음은 외금구 및 방진 고무의 상하 운동에 의해 흡수, 저감된다.The transmission mounting configured as described above, the outer bracket 2 is fixed to the transmission (not shown), the inner bracket 1 is fixed to the vehicle body (not shown), the vibration and noise transmitted from the transmission is the outer bracket and the anti-vibration rubber It is absorbed and reduced by vertical movement.

그러나, 상기와 같은 종래의 트랜스미션 마운팅은 매우 단수한 형상의 것으로, 엔진의 아이들링(idling)이나 세이크(shake)영역, 또는 자동차의 주행 속도가 100km/h 이상인 경우에 있어서는 진동 및 소음의 흡수하는데 충분한 성능을 발휘하지 못하는 단점이 있었다.However, the conventional transmission mounting as described above has a very simple shape, and is sufficient to absorb vibration and noise when the engine idling or shake area or the driving speed of the vehicle is 100 km / h or more. There was a disadvantage of not performing.

본 발명은 상기와 같은 단점을 해소하기 위해 안출된 것으로, 방진 고무의 내부에 유체가 봉입되어 유체의 작용에 의해 진동 및 소음의 흡수 성능이 향상될 수 있는 자동차의 트랜스미션 마운팅을 제공하는데 그 목적이 있다.The present invention has been made to solve the above disadvantages, the object is to provide a transmission mounting of a vehicle that can improve the absorption performance of vibration and noise by the fluid is sealed in the interior of the anti-vibration rubber. have.
