Vehicle front subframe
A vehicle front subframe includes: a pair of longitudinal members each extending in a longitudinal direction of a vehicle and having a mounting recess; an inner reinforcing member mounted in an inner cavity of each longitudinal member; and a suspension arm having a mount mounted in the mounting recess of each longitudinal member through a mount member.
1 . A vehicle front subframe, comprising:
a pair of longitudinal members each extending in a longitudinal direction of a vehicle and having a mounting recess;
an inner reinforcing member mounted in an inner cavity of each longitudinal member; and
a suspension arm having a mount mounted in the mounting recess of each longitudinal member through a mount member,
wherein the inner reinforcing member includes an upper wall, a lower wall spaced apart from the upper wall, a flange extending along an edge of the upper wall, and a connection wall connecting the upper wall and the lower wall.
2 . The vehicle front subframe according to claim 1 , wherein the inner reinforcing member extends from the mounting recess toward a front of the longitudinal member, and wherein the inner reinforcing member is fixed to the longitudinal member together with the mount member through a fastener.
3 . The vehicle front subframe according to claim 1 , wherein the longitudinal member includes an upper channel and a lower channel coupled to the upper channel, and wherein the inner cavity is defined by the upper channel and the lower channel.
4 . The vehicle front subframe according to claim 3 , wherein the flange is fixed to a lateral wall of the upper channel by welding, and wherein the lower wall is fixed to a bottom wall of the lower channel by welding.
5 . The vehicle front subframe according to claim 1 , further comprising an outer reinforcing member fixed to an exterior surface of the longitudinal member and aligned with at least a portion of the inner reinforcing member.
6 . The vehicle front subframe according to claim 5 , wherein the outer reinforcing member is configured to connect the longitudinal member and the mount member.
7 . The vehicle front subframe according to claim 5 , wherein the outer reinforcing member includes a front portion and a rear portion located behind the front portion.
8 . The vehicle front subframe according to claim 5 , wherein the outer reinforcing member has a bent portion bent at at least one edge thereof.
9 . The vehicle front subframe according to claim 7 , wherein the front portion of the outer reinforcing member is fixed to the longitudinal member together with the inner reinforcing member through a first front bolt and a first front nut.
10 . The vehicle front subframe according to claim 9 , wherein a top surface of the first front nut contacts the longitudinal member.
11 . The vehicle front subframe according to claim 9 , wherein a top surface of the first front nut contacts an upper portion of the longitudinal member, and wherein a lower portion of the first front nut extends through a through hole of the inner reinforcing member.
12 . The vehicle front subframe according to claim 9 , wherein the rear portion of the outer reinforcing member is fixed to the longitudinal member together with the mount member and the inner reinforcing member through a second front bolt and a second front nut.
13 . The vehicle front subframe according to claim 12 , wherein a top surface of the second front nut contacts an upper portion of the longitudinal member, and wherein a lower portion of the second front nut extends through a through hole of the inner reinforcing member and a through hole of a bottom of the longitudinal member.
