摘要： The twist axle assembly includes a pair of spaced apart trailing arms and a twist beam of which extends in a first direction between the trailing arms. The twist beam includes a pair of end portions and a middle portion. The twist beam further has a pair of side walls and at least one additional wall that extends between the side walls. The side walls in the middle portion are generally parallel with the side walls of the end portions. The twist beam is generally hour-glass shaped with the middle portion having a first width and the end portions have a greater second width. The twist beam also tapers from the first width of the middle portion to the second widths of the end portions for gradually increasing a torsional stiffness from the middle portion to the end portions.

摘要： The twist axle assembly includes a pair of spaced apart trailing arms and a twist beam which is made of a single piece and is operably connected with the trailing arms. The twist beam has a top wall, a bottom wall and a pair of side walls. The twist beam presents a pair of end portions which are bent to present edges that face towards one another when viewed in cross-section, and the twist beam presents a middle portion which extends between the end portions. The middle portion has an opening with a generally elliptical shape formed into the bottom wall for reducing a torsion stiffness of the middle portion of the twist beam in comparison to the end portions.
