Hollow stabilizer for vehicle

Abstract

Abstract PURPOSE: To provide a welded tube with the substantially same fatigue strength as a seamless tube in a stabilizer using a welded tube as a material by placing its bead part along the curved line whose bent part has the largest or smallest curvature. CONSTITUTION: When the thickness ration and the bending ration are large, the bead part of a welded tube at a bent part 4 of a stabilizer body 1 is placed in the region which centers on a curved line having the largest or smallest curvature and whose center angle β with respect to the tube axis XX is approximately 60°. When the thickness ration and the bending ration are small, said bead part is placed in the region which centers on a curved line having the smallest curvature and whose center angle α with respect to the tube axis XX is approximately 90°. Accordingly, no large principal stress is generated at the bead part, so that if a welded tube is used, the substantially same fatigue strength as a seamless tube can be guaranteed.
