Abstract

A control arm for an motor vehicle and method of forming the same. The control arm includes a hydroformed member and first and second stamped members. The hydroformed member has a first end forming part of a first joint and a second end. The first stamped member forms part of a second joint and is coupled to the hydroformed member between the first end and the second end thereof. The first stamped member has a section rigidly connected to the hydroformed member and a section adapted to receive a first bushing. The second stamped member forms part of a third joint and is coupled to the second end of the hydroformed member. The second member has a portion rigidly connected to the second end of the hydroformed member and a portion adapted to receive a second bushing.

Description

[0001] This application claims priority to US Provisional Patent Application No. 60 / 384,169, filed May 31, 2002, which is incorporated by reference in its entirety. technical field [0002] The invention relates to the field of motor vehicle manufacturing. More particularly, the illustrated embodiments of the invention relate to control arms for automobiles and methods of making such control arms incorporating hydroformed members. Background technique [0003] Control arms are used on motor vehicles to help support and control the various wheels of the motor vehicle. Typically, the control arms are seen attached between the frame and wheel assemblies of the motor vehicle. The construction of control arms is often complex for a number of reasons, including, for example, the number and nature of connections between the control arms and other vehicle components, and also because of the performance requirements and stresses placed on the control arms.
