Evasion Behaviour Induction type Sub Frame and Vehicle thereby

摘要

The subframe (1) of the present invention is a longitudinal member that is cross-coupled to the lateral member (20) by making a pair of a lateral member (20), a left ordinate member (10-1) and a right ordinate member (10-2). (10), each of the left vertical member (10-1) and the right vertical member (10-2) is inserted into the cutout groove (21) of the lateral member (20), and a plurality of welding fixing parts (50-1, 50-2) ,50-3) fixed avoidance behavior induction structure (1-1), damper (30) coupled to the avoidance behavior induction structure (1-1), longitudinal member (10) at a position spaced apart from the lateral member (20) Including the rear member 40 coupled to the engine room 100-1 by mounting the subframe 1, avoidance behavior in the state where the longitudinal/lateral members 10 and 20 are not separated when a small overlap collision occurs. The rotation for generation occurs, and in particular, due to the maintenance of the joint structure of the longitudinal and transverse members 10 and 20, the initial movement amount increases while the initial impact load is high, thereby greatly reducing the post-impact load.
