Re: This trailer has no suspenision!
A Torsion beam Suspension, also known as a torsion bar or torsion spring suspension, is a general term for any vehicle suspension that uses a torsion bar as its main weight bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end terminates in a lever, mounted perpendicular to the bar, that is attached to a suspension arm, spindle or the axle. Vertical motion of the wheel causes the bar to twist around its axis and is resisted by the bar's torsion resistance. The effective spring rate of the bar is determined by its length, diameter and material.
Notice how the center of the wheel/hub is not in line with the axle tube, the center of the wheel/hub moves up and down twisting the torsion bar in the center of the tube.
