Abstract: A twist axle assembly (20) of a vehicle includes a pair of trailing arms (22) and a twist beam (24) having a base portion (46) extending along an axis (A) between first and second twist beam ends (42, 44). The twist beam (24) includes a pair of side walls (48) extending downwardly from the base portion (46) and each disposed in spaced relationship with the trailing arms (22). At least one mounting bracket (54) extends from a first mounting bracket end (56) disposed in abutting relationship with a respective trailing arm (22) to a second mounting bracket end (58) disposed in overlaying relationship the side walls (48) of the twist beam (24) for allowing the mounting bracket to axially slip or slide along the side walls (48) of the twist beam (24) and provide for lateral or axial adjustment of the twist axle assembly (20) during the manufacturing process.

Abstract: 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.

Abstract: 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.

Abstract: A twist axle assembly (20) of a vehicle includes a pair of trailing arms (22) and a twist beam (24) extending along an axis (A) between first and second twist beam ends (26, 28). The twist axle assembly (20) further includes a bushing (38) interconnected to each one of the first and second twist beam ends (26, 28) and a respective trailing arm (22) for establishing a weld-less joint between the twist beam (24) and the trailing arm (24). In an embodiment, the twist beam (24) and bushings (38) are tubular, and the bushings (38) are press-fit or molded onto the respective first or second twist beam ends (36, 38). In a further embodiment, the trailing arms (26) define an orifice (40) aligned on the axis (A), and the tubular bushings (38) are press-fit into the orifices (40) of the trailing arms (26) to establish the weld-less joint.

Abstract: The twist axle assembly includes a twist beam which is made of a single integral piece and extends along a length between opposite ends. The twist beam has a middle portion which extends in a first direction and a pair of end portions which extend at least partially in a second direction that is generally transverse to the first direction to reduce twisting stresses within the end portions during operation of the twist axle assembly.
