Embodiment Construction

[0018] Below by using Figure 1 to Figure 3 Embodiments of the vehicle front structure related to the present invention are described. Note that arrow FR shown in these drawings indicates the vehicle longitudinal front side, arrow OUT indicates the vehicle transverse outer side, and arrow UP indicates the vehicle vertical direction upper side.

[0019] like figure 1 As shown, an engine room 11 in which an unshown engine unit is accommodated is provided at a front portion 12 of the vehicle 10 . A front side member 14 serving as a pair of left and right side members and having an interval therebetween and extending in the vehicle longitudinal direction, and a bumper reinforcement 16 mounted to front end portions of the pair of left and right front side members 14 are provided. Inside the engine compartment 11 . In addition, the front portion 12 of the vehicle 10 has a suspension beam 18 to which an unshown suspension arm, a steering gear box, and the like are mounted.

Abstract

A vehicle front portion structure has: a suspension member provided at a vehicle lower side of side members and supported by the side members, the suspension member having a main body portion that extends in a vehicle transverse direction, and a pair of left and right arm portions, each of which extends toward a vehicle front side from a vehicle transverse direction end portion of the main body portion; a front cross member connecting a distal end portion of one of the arm portions and a distal end portion of another of the arm portions in the vehicle transverse direction; and a pair of left and right braces extending obliquely toward vehicle transverse direction outer sides while heading toward a vehicle rear side, front end portions of the braces being joined to the front cross member, and rear end portions of the braces being joined to the arm portions.

Description

technical field [0001] The present invention relates to a vehicle front structure. Background technique [0002] A vehicle front structure is disclosed in Japanese Patent Application Laid-Open (JP-A) No. 2012-6545. Specifically, the vehicle front structure has: a pair of left and right front side frames extending in the vehicle longitudinal direction at the front of the vehicle body; and a suspension beam mounted to the front side frames. The suspension beam has a pair of left and right longitudinal beams extending in the vehicle longitudinal direction, and crash cans are respectively coupled to front end portions of these longitudinal beams. In addition, a front cross member extending in the vehicle transverse direction is joined to the vehicle front portion of the longitudinal member and the vehicle rear side of the crash can. Thus, the left and right longitudinal beams are connected in the vehicle transverse direction. Therefore, the bending rigidity of the suspension ...
