A suspension system for a rear axle of a vehicle provided with a frame equipped with at least two side members, the suspension system connecting the axle to said side members and comprising a left side and a right side, each comprising an axle-holder assembly, a bellows, a leaf spring, first and second bars, and a torsion bar interposed between said left and right sides. The aforementioned elements of the suspension system being arranged to provide a functional layout having reduced costs and overall dimensions.

An axle hanger includes a web, a first flange extending in a first direction perpendicular to the web, and a second flange extending in the first direction perpendicular to the web, spaced from and parallel to the first flange. A first return extends from the first flange toward the second flange parallel to the web, and a second return extends from the second flange toward the first flange parallel to the web. The axle hanger is easier to install and access in the event a hanger spring needs replacement, and the hanger can be more stably secured to the axle.

A tandem mechanical spring axle/suspension system for heavy-duty vehicles includes a tandem assembly that comprises a front beam of a suspension assembly of a front axle/suspension system, a rear beam of a suspension assembly of a rear axle suspension system, and a mechanical spring. The mechanical spring operatively engages the front beam and the rear beam and extends longitudinally therebetween, as well as operatively engages a main member of the vehicle frame.
