Abstract: A spring support for a motor vehicle has a center tube frame with a backbone tube supported through a pair of spaced apart transverse beams, and a pair of final drive casings spaced apart and mounted to the center tube frame on the backbone tube. Pairs of half-axles are mounted for swinging motion on each final drive casing. Pairs of fluid springs are mounted between a bracket connected to the backbone tube and each half-axle by seats provided on each bracket engaged with the fluid spring. Each seat is oriented to form an acute angle with a vertical axis symmetry plane of the center tube frame. Inclined rigid struts having an upper portion and a foot portion connect each fluid spring, to the corresponding half-axle. An embodiment in which two pairs of half-axles are supported on the center tube frame by fluid springs and a mechanical spring connected at a spring center to each side of the central tube frame further supports one half-axle of each pair of half-axles is also provided.
