Abstract
Official abstract text for this publication.
Provided is a vehicle frame structure including (1) a first frame member that has a closed cross-sectional shape as seen in a cross-sectional view orthogonal to an extension direction and (2) a second frame member that extends along the first frame member, overlaps a wall surface of the first frame member, and has a hole portion that exposes the wall surface, with an edge portion of the hole portion being joined to the wall surface by a linear welded portion, wherein both end portions of the welded portion are disposed in close proximity to a neutral axis of the first frame member and the second frame member in a case in which the first frame member and the second frame member have undergone bending deformation in an in-plane direction of the wall surface in which the welded portion is formed.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle suspension member structure comprising: a first frame member that has a closed cross-sectional shape as seen in a cross-sectional view orthogonal to an extension direction of the first frame member; and a second frame member that extends along the first frame member, overlaps a wall surface of the first frame member, and has a hole portion that exposes the wall surface, with an edge portion of the hole portion being joined to the wall surface by a linear welded portion, wherein both end portions of the welded portion are disposed in close proximity to a neutral axis of the first frame member and the second frame member in a case in which the first frame member and the second frame member have undergone bending deformation in an in-plane direction of the wall surface on which the welded portion is formed. 2. The vehicle suspension member structure according to claim 1 , wherein the welded portion is provided on both sides of the neutral axis. 3. The vehicle suspension member structure according to claim 2 , wherein the welded portions are provided so as to be line-symmetric to each other with the neutral axis serving as the axis of symmetry. 4. The vehicle suspension member structure according to claim 1 , wherein the welded portion has a first weld line extending along the extension direction, second weld lines extending in a direction orthogonal to the extension direction, and curving weld lines that interconnect the first weld line and the second weld lines. 5. The vehicle suspension member structure according to claim 4 , wherein the first weld line is formed in a wave shape. 6. A vehicle frame structure comprising: a first frame member that has a closed cross-sectional shape as seen in a cross-sectional view orthogonal to an extension direction of the first frame member; and a second frame member that extends along the first frame member, overlaps a wall surface of the first frame member, and has a hole portion that exposes the wall surface, with an edge portion of the hole portion being joined to the wall surface by a linear welded portion, wherein both end portions of the welded portion are disposed in close proximity to a neutral axis of the first frame member and the second frame member in a case in which the first frame member and the second frame member have undergone bending deformation in an in-plane direction of the wall surface on which the welded portion is formed, and wherein the welded portion has a first weld line extending along the extension direction, second weld lines extending in a direction orthogonal to the extension direction, and curving weld lines that interconnect the first weld line and the second weld lines. 7. A vehicle frame structure comprising: a first frame member that has a closed cross-sectional shape as seen in a cross-sectional view orthogonal to an extension direction of the first frame member; and a second frame member that extends along the first frame member, overlaps a wall surface of the first frame member, and has a hole portion that exposes the wall surface, with an edge portion of the hole portion being joined to the wall surface by a linear welded portion, wherein both end portions of the welded portion are disposed in close proximity to a neutral axis of the first frame member and the second frame member in a case in which the first frame member and the second frame member have undergone bending deformation in an in-plane direction of the wall surface on which the welded portion is formed, wherein the welded portion has a first weld line extending along the extension direction, second weld lines extending in a direction orthogonal to the extension direction, and curving weld lines that interconnect the first weld line and the second weld lines, and wherein the first weld line is formed in a wave shape.
