Abstract
Official abstract text for this publication.
A suspension arm includes an arm body having a longitudinal shape, a wheel-side attachment portion disposed at one end of the arm body, and a vehicle body-side attachment portion disposed at the other end of the arm body, and is mounted near a drive shaft to extend in a lateral direction of a vehicle, the arm body including an overlap portion that overlaps the drive shaft as viewed from a front in a longitudinal direction of a vehicle, a weak portion having lower strength than the overlap portion being provided between the overlap portion and the wheel-side attachment portion, the arm body having a hollow longitudinal shape, and portions on both sides of the weak portion being quenched by high frequency heating so as to have high strength, such that the weak portion is partially provided at an intermediate position between the overlap portion and the wheel-side attachment portion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A suspension arm, which includes an arm body having a longitudinal shape, a wheel-side attachment portion that is disposed at one end of the arm body, and a vehicle body-side attachment portion that is disposed at the other end of the arm body, and which is mounted near a drive shaft so as to extend in a lateral direction of a vehicle, the arm body including an overlap portion that overlaps the drive shaft as viewed from a front in a longitudinal direction of the vehicle, a weak portion having lower strength than the overlap portion being provided between the overlap portion and the wheel-side attachment portion, the arm body having a hollow longitudinal shape, and portions on both sides of the weak portion being quenched by high frequency heating so as to have high strength, such that the weak portion is partially provided at an intermediate position between the overlap portion and the wheel-side attachment portion. 2. The suspension arm according to claim 1 , wherein the overlap portion has higher strength than the weak portion by quenching treatment using high frequency heating. 3. The suspension arm according to claim 1 , wherein the suspension arm is mounted such that the wheel-side attachment portion and the vehicle body-side attachment portion are positioned above the drive shaft as viewed from the front, and the arm body includes a curved portion located on its vehicle body-side attachment portion side and curved so as to protrude toward a lower side of the vehicle, and a lower end of the curved portion serves as the overlap portion.
