Abstract
The present invention relates to a link member for a vehicle having bracket portions at both ends and an intermediate connecting both bracket portions and arranged at an intermediate portion. The link member for a vehicle is constituted by an integrally formed product formed by deforming a pipe-shaped workpiece W1 by plastic working. The intermediate connecting portion is provided with an intermediate shaft portion 3 having a diameter smaller that that of the bracket portion 2, and a thickness of a peripheral wall of the bracket portion 2 is different from that of a peripheral wall of the intermediate shaft portion 3. This increases strength and durability of the link member.
Claims17
A link member for a vehicle having bracket portions at both ends of the link member and an intermediate connecting portion connecting the bracket portions and arranged at an intermediate portion of the link member, wherein
- the link member is constituted by an integrally formed product obtained by deforming a pipe-shaped workpiece by plastic working;
- the intermediate connecting portion is provided with an intermediate shaft portion having a diameter smaller than that of the bracket portion;
- and
- a peripheral wall of the bracket portion is formed to have a thickness different from that of a peripheral wall of the intermediate shaft portion.
A method of manufacturing a link member for a vehicle having bracket portions at both ends of the link member and an intermediate connecting portion connecting the bracket portions and arranged at an intermediate portion of the link member, wherein
- a pipe-shaped workpiece is deformed by plastic working to thereby manufacture the link member for a vehicle in which an intermediate connecting portion is provided with an intermediate shaft portion having a diameter smaller than that of the bracket portion, a peripheral wall of the bracket portion is formed to have a thickness different from that of a peripheral wall of the intermediate shaft portion, and the link member is constituted by an integrally formed product.
A method of manufacturing a suspension arm for an automobile having bracket portions at both ends of the suspension member and an intermediate connecting portion connecting the bracket portions and arranged at an intermediate portion of the suspension member, wherein
- a pipe-shaped workpiece is deformed by plastic working to thereby manufacture the suspension arm for an automobile in which an intermediate connecting portion is provided with an intermediate shaft portion having a diameter smaller than that of the bracket portion, a peripheral wall of the bracket portion is formed to have a thickness different from that of a peripheral wall of the intermediate shaft portion, and the link member is constituted by an integrally formed product.
