Abstract
Official abstract text for this publication.
A hollow stabilizer ( 1 ) according to the invention is formed in a hollow shape and includes a bent portion ( 1 c 1, 1 c 2 , m 1 -m 5 ). With a thickness of an inner side of the bent portion ( 1 c 1, 1 c 2 , m 1 -m 5 ) being larger than a thickness of an outer side of the bent portion ( 1 c 1, 1 c 2 , m 1 -m 5 ), a hardness of the outer side of the bent portion ( 1 c 1, 1 c 2 , m 1 -m 5 ) is higher than a hardness of the inner side of the bent portion ( 1 c 1, 1 c 2 , m 1 -m 5 ) through quenching by cooling down after heating by electrical heating.
First claim
Opening claim text (preview).
The invention claimed is: 1. A hollow stabilizer, comprising: a torsion bar portion extending longitudinally; an arm portion extending transversely to the torsion bar portion; and a curved portion extending between the arm portion and the torsion bar portion, the curved portion having an inner wall and an outer wall in a radial direction of a curvature of the curved portion, wherein with a thickness of the inner wall of the curved portion being larger than a thickness of the outer wall of the curved portion, a hardness of the outer wall of the curved portion is made higher than a hardness of the inner wall of the curved portion. 2. The hollow stabilizer according to claim 1 , wherein a range of a durability of an entire region of the hollow stabilizer is made equal to a desired range such that a weight of the hollow stabilizer is lightest. 3. The hollow stabilizer according to claim 1 , wherein outer diameters and the thicknesses throughout the hollow stabilizer are set such that stress of an entire area of the hollow stabilizer is within a range of allowable stresses and a weight of the hollow stabilizer is lightest.
