Title:
SUSPENSION ARM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2007/020938
Kind Code:
A1
Abstract:
A suspension arm for a vehicle, comprising an arm body (1) having a main plate body
(2) press-molded to form the main part of the arm body and having a short cylindrical
part (EB) integrally continued therewith at its one end by burring process and
a reinforcement plate (H) stacked on one of the upper and lower surfaces of the
main plate body (2) for reinforcing the main plate body (2). The reinforcement
plate (H) comprises an eye-like head part (Ha) formed in a circular ring shape
and arranged coaxially with the short cylindrical part (EB) and a tail part (Hb)
integrally extending from the eye-like head part (Ha) along the longitudinal
direction of the main plate body (2). The reinforcement plate is formed of a single
plate material larger in thickness than the main plate body (2), at least the tail
part (Hb) is welded to the main plate body (2), and a bush press-fitting part (P1)
is formed by the inner peripheral surface of the eye-like head part (Ha) and the
inner peripheral surface of the short cylindrical part (EB). Thus, since the
cross sectional area of the transient portion of the arm body from the bush press-fitting
part to the arm body can be sufficiently secured, a rigidity required for the transient
portion can be easily secured, and the strength of the arm can be increased without
increasing the outer peripheral space of the bush press-fitting part.
