ENGINE-FIXING CROSS MEMBER FOR REDUCING WEIGHT BY INTEGRATING A BODY AND A FIXING ARM AND WELDING AN ENGINE MOUNTING BRACKET TO THE CROSS MEMBER, AND PREVENTING RESONANCE ABOUT VIBRATION GENERATED FROM AN ENGINE

摘要

PURPOSE: An engine-fixing cross member is provided to reduce noise for vibration generated from an engine by combining upper and lower plates to each other and welding an engine mounting bracket to both ends of the cross member. CONSTITUTION: A cross member(10) for fixing an engine to a vehicle body is formed by jointing upper and lower plates(30,20), which are formed in a same shape, to each other. An engine mounting bracket(40) is welded and fixed to both ends of the cross member. The stability of the engine mounting bracket is increased without receiving influence of the external vibration by removing a fixing arm and bending the cross member. Noise is decreased in using the cross member for vibration of the engine below 500Hz.
