Torsional rigidity increase structure of automobile front structure

摘要

In a front structure of a passenger car of a McFuns type in which a front cross member is not installed, a torsional rigidity increasing structure (1) is provided on the front side member (3);;The torsional rigidity increasing structure 1 described above welds the front cross member 2 to the front side member 3 and mounts the lower arm on the front cross member 2;;The front cross member (2) has a rectangular main member (7) at the center; A hollow rectangular post 8 welded to the left and right ends of the main member 7; And a bracket 9 welded to a side surface of the rectangular post 8 as described above.;The torsional rigidity increasing structure (1) of the automotive front structure of the present invention is characterized in that the front cross member (2) having increased rigidity is welded to the front side member (3) and the lower cross member It is possible to improve the steering and handling characteristics of the vehicle and to greatly improve the torsional rigidity and durability of the vehicle. In addition, since the front cross member 2, So that the engine center member and other various parts can be mounted.
