SUB FRAME SUPPORTING STRUCTURE BY USING FRONT END MODULE FOR MINIMIZING TRANSMISSION OF VIBRATION INPUT FROM SUB FRAME TO VEHICLE BODY BY TRANSMITTING PRIMARILY ENGINE IDLE AND ACCELERATION NOISE THROUGH ROLL MOUNTING UNIT OF SUB FRAME AND THEN SECONDARILY THROUGH MOUNTING UNIT OF SUB FRAME

摘要

PURPOSE: A sub frame supporting structure by using a front end module is provided to improve strength for load input horizontally to sub frame front mounting unit by installing a stay supporting bracket at a lower end of a bumper mounting unit and forming a stay for connecting a front end module bracket at the lower end of the sub frame front mounting unit. CONSTITUTION: In a structure for mounting a front end module(2) at a front side member of a vehicle body and supporting a sub frame of an engine room at the front end module, a sub frame supporting structure by using the front end module is composed of a stay supporting bracket(10) installed at the lower end of a bumper mounting unit of a steel structure part of the front end module and formed with a bolt hole(11) keeping the predetermined gap and a stay connected at the stay supporting bracket to support the lower end of the front mounting unit of the sub frame by forming a supporting unit and a fixing unit corresponding to the bolt hole.
