AIR SUSPENSION SYSTEM

摘要

A load carrying member for an air suspension system is disclosed. The load carrying member is a seamless tube comprising a straight mid portion, a left end portion and a right end portion. Each of the left and right end portions are bent or curved with a predetermined radius of curvature so that the said straight mid portion and both the curved left and right end portions form a shape of a cross-section of bath tub. The wall of the tube at the bent portion has thickness which substantially same as the thickness of wall of the straight mid portion. The load carrying member according to the invention not only obviates the problem of frequent failure, but also reduces the number of process steps of manufacturing.
