Abstract
Official abstract text for this publication.
A stabilizer including: a main body for generating an elastic restoring force; and connecting portions formed on both ends of the main body and respectively connected to left and right suspension devices. Hardness of the connecting portions is lower than that of the main body. A method for manufacturing the stabilizer includes, in order, an entire body heat treatment process for heat treating an entire stabilizer and increasing hardness of the entire stabilizer, and a connecting portion softening process for heating the connecting portions and reducing the hardness of the connecting portions. The method for manufacturing the stabilizer thereby increases hardness of the main body and reduces the hardness of the connecting portions lower than that of the main body.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a stabilizer comprising: providing an elastic main body of the stabilizer including a torsion portion, shoulder bent portions bent respectively from both ends of the torsion portion, and arm portions extending respectively from the shoulder bent portions; and connecting portions on both ends of the elastic main body and respectively connected to left and right suspension devices, the elastic main body and the connecting portions constituting an entire stabilizer; an entire body heat treatment process of heating and quenching the entire stabilizer of the torsion portion, the shoulder bent portions, the arm portions, and the connecting portions to increase hardness of the entire stabilizer; and a connecting portion softening process, after the entire body heat treatment process, of reducing hardness of at least one connecting portion by heating the at least one connecting portion while the elastic main body is kept from being heated, thereby manufacturing the stabilizer comprising the at least one connecting portion lower in hardness than the torsion portion, the shoulder bent portions, and the arm portions of the elastic main body. 2. The method for manufacturing the stabilizer according to claim 1 , wherein the connecting portion softening process includes applying high-frequency heat or electrically heating the at least one connecting portion.
