The present invention relates to a rear mounting structure for an automotive power train. Although an existing mounting structure can stably maintain a vibration insulation function, the mounting structure can introduce vibrations into the interior of a vehicle due to a deterioration in a vibration control function with a driving reaction, which can result in a problem with a decline in ride comfort. To solve the problem, according to the present invention, the rear mounting structure for an automotive power train, which is mounted between the rear of a power train (100) and a vehicle frame (200), comprises: a housing (300) mounted in the vehicle frame (200) through a frame mounting part (310), and having a predetermined space part (301) provided in the center for the installation of a vibration insulator; a hinge part (320) laid in the center of the space part (301) of the housing (300), and having a hinge hole (321); a main rubber (330) supporting a lower end of a vibration adsorption part (331) in a reverse v-shaped form from both lower corners in the housing (300) such that the hinge part (320) provided with the hinge hole (321) and the vibration absorption part (331) surrounding an outer circumference surface of the hinge part (320) can be laid in the center of the space part (301) of the housing (300); and stopper rubbers (340) provided at both upper ends in the housing (300) to absorb driving reaction vibrations. Therefore, the rear mounting structure can stably maintain a vibration insulation function while improving a vibration control function with a driving reaction.

    본 발명은 자동차용 파워트레인의 리어 마운팅 구조에 관한 것으로서 종래 마운팅 구조는 진동절연 기능은 안정적으로 유지할 수 있으나 구동반력에 의한 진동 제어 기능은 저하되어 진동이 차량의 실내로 유입되면서 승차감이 떨어지는 문제점이 있었다. 따라서 본 발명은 파워트레인(100)의 후미와 차체 프레임(200) 사이에 장착되는 자동차용 파워트레인의 리어 마운팅 구조에 있어서, 프레임 장착부(310)에 의해 차체 프레임(200)에 장착되며, 진동절연체 설치를 위해 중앙에 소정의 공간부(301)가 구비되는 하우징(300); 하우징(300)의 공간부(301) 중앙에 놓이며, 힌지공(321)이 구비된 힌지부(320); 힌지공(321)이 있는 힌지부(320) 및 힌지부(320) 외주면을 감싸는 진동흡수부(331)가 하우징(300)의 공간부(301) 중앙에 놓이도록 하우징(300) 내의 양쪽 하단 모서리에서 진동흡수부(331)의 하단을 '∧'형태로 받쳐주는 메인러버(330); 하우징(300) 내의 양쪽 상단에 구비되어 구동반력 진동을 흡수하는 스톱퍼 러버(340);로 구성하여 진동절연 기능을 안정적으로 유지하면서 구동반력에 의한 진동제어 기능이 향상되게 한 매우 유용한 발명이다.
