Abstract
A suspension linkage for a motor vehicle includes an extruded body having a first wall and a longitudinal length. An extruded feature is disposed on the first wall of the extruded body and extends along the longitudinal length. The extruded feature has a cross-sectional profile configured to control a flexural rigidity of the suspension linkage.
Claims16
A suspension linkage for a motor vehicle comprising:
- an extruded body having a longitudinal length and having a fixed cross-sectional profile along a portion of the longitudinal length that is created by pushing a material through a die that defines the fixed cross-section, the extruded body having an enclosed hollow cross-section, the extruded body having a first wall having a first thickness, the first wall forming a portion of the enclosed hollow cross-section along at least a portion of the longitudinal length;
- and
- an extruded rib projecting from a surface of the first wall of the extruded body and extending along the entire longitudinal length of the first wall, the rib having a proximal end connected to the first wall and an opposite unconnected distal end spaced away from the first wall, wherein the extruded rib has a thickness greater than the first thickness and has a cross-sectional profile configured to control a flexural rigidity of the suspension linkage;
- wherein the rib is located on an outer surface of the first wall of the extruded body and the rib projects from the outer surface;
- wherein the first wall has a first edge and a second edge defining a width of the first wall;
- wherein the rib has a first side and a second side defining a width of the rib and wherein the first and second sides are spaced inward from the first and second edges.

A suspension linkage for connecting a suspension unit to a frame of a motor vehicle, the suspension linkage comprising:
- an extruded body having a longitudinal length and having a fixed cross-sectional profile along a portion of the longitudinal length that is created by pushing a material through a die that defines the fixed cross-section, the extruded body having a first wall having a first thickness, a second wall, and a third wall;
- and
- an extruded rib disposed on the first wall of the extruded body, the rib having a proximal end connected to the first wall and an opposite unconnected distal end spaced away from the first wall, wherein the extruded rib has a cross-sectional profile for tuning a flexural rigidity of the suspension linkage, a thickness of the extruded rib is greater than the first thickness, and a width of the extruded rib is less than half of a width of the first wall;
- wherein the rib is located on an outer surface of the first wall of the extruded body and the rib projects from the outer surface, wherein a second wall connects to the first wall at a first corner and a third wall connects to the first wall at a second corner, wherein the rib has a first side and a second side defining a width of the rib and the first and second sides are spaced inward from the first and second corners.
