A stabiliser bar apparatus for use in a vehicle suspension

摘要

A stabiliser bar apparatus for use in a suspension of a motor vehicle includes a hollow tubular member (22) having first and second arms (24,26) disposed at opposite ends of a center section (28). The center section is adapted to be rotatably attached to a chassis and the first and second arms are adapted to attach to first and second wheel suspensions, respectively. A first radial protrusion (38) is circumferentially formed on an outer surface of the hollow tubular member and extends radially outward from the outer surface to a first predetermined height sufficient to retain the stabilizer bar under lateral loading. Additionally, a stress dispersing formation is (46) formed on an inner surface of the hollow tubular member opposite the first radial protrusion so as to disperse stress that would otherwise concentrate in the hollow tubular member adjacent to the first radial protrusion.
