Front sub-frame structure and method of assembling the front sub-frame

摘要

PROBLEM TO BE SOLVED: To provide a front sub-frame structure for balancing the layout of a power train with the assemblability of a suspension arm and the improvement in collision safety such as dispersion of collision load and load absorbing deformation of a front side member without special reinforcement for a suspension member body in higher dimensions by forming a low-rigidity front support part opened to the outside and a front collision load transmission route by utilizing an arm front fitting part without narrowing the disposition space for an arm fitting bolt or the power train.;SOLUTION: A front end part of a front side member 18 is extended forward from a power train, and the rear end part of the front side member 18 is shaped to cover an arm fitting bolt of a suspension arm 15. The rear end part of the front side member 18 is supported by a support part 44 provided on an outer part in the vehicle width direction from the arm fitting bolt of an arm front support part by abutting on the front of an arm front support part 40 through a rubber member.;COPYRIGHT: (C)2014,JPO&INPIT
