Mounting structure of auxiliary frame of automobile body

摘要

The present invention is to improve the auxiliary frame mounting structure of the vehicle body.;Since the width of the side frame is determined by the width of the vehicle body according to the related art, the mounting position of the suspension to be mounted thereon is fixed and there is no freedom of setting the mounting position. The members 13 and 13 are extended, and the cross member 21 which extends in the left-right direction is joined to this side member, and the bracket 31 is joined in the joining position of the side members 13 and 13 and the cross member 21. As shown in FIG. ), And this bracket is joined to both side members and cross members, and the bracket is formed by a vehicle body auxiliary frame mounting structure in which an auxiliary frame 38 for mounting a suspension or the like is mounted on the bracket. Since the mounting position of the auxiliary frame can be freely set within the range, the degree of freedom in setting the mounting position in the width direction of the vehicle body can be increased. Im mounting portion, it is possible to increase the rigidity of the bonded portion of each side member and cross member.
