Abstract
A suspension structure for vehicle (a suspension arm for vehicle) is formed of a first plate and a second plate, and includes a mounting part for mounting a component (a collar or a bush). The first plate is partially open toward a first flat plate part so that a first mounting surface can be formed by stamping in a state of a single unit where a first flat plate part is bent. The second plate is also partially open toward a second flat plate part. The mounting part is configured by facing the first flat plate part of the first plate and the second flat plate part of the second plate each other at a distance, and disposing the first mounting surface and a second mounting surface at a distance.
Claims11
A suspension structure for vehicle comprising:
- a main body that is formed of at least a first plate and a second plate which are stamped products and that includes at least a portion whose cross section has a rectangular shape;
- and a mounting part for mounting a component for vehicle suspension,
- wherein the first plate includes:
- a first main body included in the main body;
- a first flat plate part extending in continuity with a main surface of the first main body and being bent so as to form an L-shape with respect to the main surface;
- and a first mounting surface formed on the first flat plate part at a first mounting end portion of the first plate and to abut on an outer surface of the component,
- the second plate includes:
- a second main body, which is together with the first main body of the first plate included in the main body;
- a second flat plate part extending in continuity with a main surface of the second main body and being bent so as to form an L-shape with respect to the main surface;
- and a second mounting surface formed on the second flat plate part at a second mounting end portion of the second plate and to abut on the outer surface of the component,
- the first plate is partially open toward the first flat plate part so that the first mounting surface can be formed by stamping in a state of a single body in which the first flat plate part is bent, and a cross-section of the first plate at the first mounting end portion is L-shaped,
- the second plate is partially open toward the second flat plate part so that the second mounting surface can be formed by stamping in a state of a single body in which the second flat plate part is bent, and a cross-section of the second plate at the second mounting end portion is L-shaped,
- the main body is configured by facing the first main body of the first plate and the second main body of the second plate each other, and
- the mounting part is configured by, at the first and second mounting end portions, facing the first flat plate part of the first plate and the second flat plate part of the second plate each other at a distance, and disposing the first mounting surface and the second mounting surface at a distance.

A method of manufacturing a suspension structure for vehicle including:
- a main body that is formed of at least a first plate and a second plate which are stamped products and that includes at least a portion whose cross section has a rectangular shape;
- and a mounting part for mounting a component for vehicle suspension, comprising:
- forming, on the first plate, a first main body included in the main body and a first flat plate part extending in continuity with a main surface of the first main body and being bent so as to form an L-shape with respect to the main surface;
- forming a first mounting surface to abut on an outer surface of the component on the first flat plate part at a first mounting end portion of the first plate by making the first plate where the first flat plate part is bent to abut on a die and stamped, wherein a cross-section of the first plate at the first mounting end portion is L-shaped;
- forming, on the second plate, a second main body, which is together with the first main body of the first plate included in the main body, and a second flat plate part extending in continuity with a main surface of the second main body and being bent so as to form an L-shape with respect to the main surface;
- forming a second mounting surface to abut on the outer surface of the component on the second flat plate part at a second mounting end portion of the second plate by making the second plate where the second flat plate part is bent to abut on the die and stamped, wherein a cross-section of the second plate at the second mounting end portion is L-shaped;
- and
- making the first main body of the first plate and the second main body of the second plate in a state of facing each other, and furthermore making the first flat plate part of the first plate and the second flat plate part of the second plate to face each other at a distance, and in a state in which the first mounting surface and the second mounting surface at the first and second mounting end portions are disposed at a distance, the first plate and the second plate are combined by welding joint to form the main body and the mounting part.
