MOUNTING STRUCTURE OF SUSPENSION CROSS MEMBER

PROBLEM TO BE SOLVED: To firmly mount a suspension cross member to a front frame, and surely release them in case of occurrence of collision. SOLUTION: In the mounting structure of a connection arm 7 (the suspension cross member (SCM) 1) and the front frame 3, a middle part of the connection part is supported at a fulcrum S from the rear in the longitudinal direction of the vehicle according to a relative movement in the longitudinal direction of the connection arm 7 and the front arm 3 in accompany with the occurrence of the collision in case of occurrence of the collision of the vehicle. Therefore, the connection part is oscillated by the principle of the lever which makes the middle part a support part (the fulcrum S), the front side a point T of action, and the bolt insertion hole of the upper and lower surfaces of the upper end part of the connection arm 7 by the movement toward the rear of the vehicle of SCM1. Thereby the connection part is broken, and the connection state of SCM1 with the front frame 3 is released. COPYRIGHT: (C)2004,JPO
