<p>A discrete mounting point type cross member of the present invention comprises: a front member (3) connected to a right side car body frame (100-2) with a second mounting point (3-1) formed on one side; a rearward member (5) connected to a left side car body frame (100-1) with a third mounting point (5-1); a left side member (7) connected to the left side car body frame (100-1) with a first mounting point (7-1); and a right member (9) connected to the right side car body frame (100-2) with a fourth mounting point (9-1), wherein the front member (3) and the rearward member (5) facing each other and the left side member (7) and the right member (9) facing each other are formed in a hash key shape. It is possible to secure the stiffness for the suspension support and secure high oscillation frequency (mode shape) for noise and vibration isolation.</p> |
