Scusate ma sono in un forum di automobili o uno di chiacchieroni da bar??? Minchia ma siete forti eh???
La Corvette ha le balestre......e liquidate cosi' la cosa eh?? Cose se fosse una vecchia 1100....
Ecco cosa intendo per "balestra" in senso non tradizionale.
Beh leggetevi qualche articolo tecnico e capirete...
http://en.wikipedia.org/wiki/Corvette_leaf_springsLa balestra trasversale posteriore (le sospensioni sono entrambe a quadrilateri, davanti e dietro) della Corvette e stata scelta per ragioni tecniche ben precise (leggetevi l'articolo)
Tra l'altro e' in materiali compositi e' costa OLTRE IL DOPPIO rispetto alle molle normali.
Alcuni passi dell'articolo
"Since 1963, transverse leaf springs have been an integral part of the suspension of GM's Chevrolet Corvette. This article concerns the practical differences between leafs and coils, popular misconceptions, and the design considerations that led to their inclusion in the Corvette."
Advantages of transverse leaf springs
Less unsprung weight. Coil springs contribute to unsprung weight; the less there is, the more quickly the wheel can respond at a given spring rate.
Less weight. The C4 Corvette's composite front leaf weighed 1/3 as much as the pair of conventional coil springs it would replace.
Weight is positioned lower. Coil springs and the associated chassis hard mounts raise the center of gravity of the car.
Superior wear characteristics. The Corvette's composite leaf springs last longer than coils, though in a car as light as the Corvette, the difference is not especially significant. No Corvette leaf has ever been replaced due to fatigue failure.
As used on the Corvette, ride height can be adjusted by changing the length of the end links connecting the leaf to the suspension arms. This allows small changes in ride height with minimal effects on the spring rate.
Also as used on the Corvette, the leaf spring acts as an anti-roll bar, allowing for smaller and lighter bars than if the car were equipped with coil springs.
[edit]
Disadvantages of transverse leaf springs
Packaging can be problematic; the leaf must span from one side of the car to the other. This can limit applications where the drivetrain, or another part, is in the way.
Materials expense. Steel coils are commodity items; a single composite leaf spring costs more than two of them.
Design complexity. Composite monoleafs allow for considerable variety in shape, thickness, and materials. They are inherently more expensive to design, particularly in performance applications.
Susceptibility to damage. Engine fluids and exhaust modifications like cat-back removal might weaken or destroy composite springs over time. The spring is more susceptible to heat related damage than conventional steel springs.
Perception. Like pushrod engines, the leaf spring has a stigma that overshadows its advantages.
Viene specificato molto spesso il COSTO SUPERIORE di tale soluzione tra gli svantaggi....
