Abstract
An arm for a vehicle suspension has at least two connecting portions and a communicating portion. The at least two connecting portions are connectable to a vehicle suspension. The communicating portion communicates each of the at least two connecting portions and receives a bending force. The communicating portion has at least three beam portions that extend along a communicating direction of the communicating portion and do not exist in the same plane. Accordingly, it is possible to secure enough strength against a bending force, as well as, to forge an arm whose weight was reduced without impairing the required characteristics.
Claims20
An arm comprising:
- at least two connecting portions connectable to a vehicle suspension;
- and
- a communicating portion that communicates each of said at least two connecting portions along communicating directions, said communicating portion receiving a bending force and having at least three beam portions that extend along each communicating direction and do not occupy the same plane.
A process for forging an arm comprising the steps of:
- forming at least two connecting portions that are connectable to a vehicle suspension and a communicating portion that communicates each of said at least two connecting portions, said communicating portion being formed with at least three beam portions extending along a communicating direction;
- and
- bending said at least three beam portions of said communicating portion such that said at least three beam portions do not occupy the same plane.
An arm according to claim l, wherein said communicating portion has six beam portions.
