Abstract
Official abstract text for this publication.
A sub-frame assembly for supporting a pair of wheels on a vehicle. The base may be an extrusion having a matrix of panels extending in a vertical direction. The sub-frame assembly has control arm brackets disposed on opposing ends of the base and attachment towers extending above the brackets providing attachment points to connect portions of an independent suspension to the vehicle and support a pair of wheels. The base, control brackets and attachment towers may be individual modular pieces. Left and right hand control brackets and attachment towers may be provided by respective unitary support pieces attached to opposing ends of the base. The unitary support pieces may be extrusions having panels extending in a transverse direction, nonaxial to the base. The base, control arm brackets and attachment towers, alternatively, may be provided by a single unitary extrusion having a matrix of panels extending in a transverse direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of manufacturing a light-metal sub-frame for a vehicle comprising: extruding a base; extruding a control arm bracket; extruding an attachment tower; and assembling the base and the attachment tower to the control arm bracket such that extruded directions of the base, control arm bracket and attachment tower are nonaxial. 2. A method of manufacturing a light-metal sub-frame for a vehicle comprising: extruding a base; extruding a control arm bracket; extruding an attachment tower; and assembling the base and the attachment tower to the control arm bracket by friction stir welding the base and the attachment tower to the control arm bracket such that extruded directions of the base, control arm bracket and attachment tower are nonaxial.
