The third-generation Corvette offered an optional FRP mono-leaf spring as an alternative to the standard multi-leaf steel spring, the 22-kilogram (48 lb) steel spring being replaced by a 3-kilogram (7 lb) FRP spring. [9] Volvo claims a weight savings of 5 kilograms (10 lb) by using a FRP spring in the rear suspension of its second-generation ...
Unlike coil springs, leaf springs also locate the rear axle, eliminating the need for trailing arms and a Panhard rod, thereby saving cost and weight in a simple live axle rear suspension. A further advantage of a leaf spring over a helical spring is that the end of the leaf spring may be guided along a definite path.
The composite leaf springs are much lighter and sit much lower than typical coil springs and help provide the C5 with its smooth ride characteristics and low ride height. Ending production on July 2, 2004, the C5 became both the last generation of Corvette, and alongside the Lotus Esprit (the last Esprit rolled off the production line on ...
Swing axle suspensions often used leaf springs and shock absorbers, though later Mercedes-Benz applications used coil springs and the VW beetle swing axle was torsion bar sprung. One problem inherent in the swing axle concept is that it almost enevitably results in a very high roll centre which causes detrimental jacking effects and camber ...
The FRP spring reduced weight and eliminated the inner leaf friction as compared to the multi-leaf metal spring which was standard on the car. [ 2 ] Rather than centrally mounting the transverse leaf spring and thus isolating the left and right sides of the springs, some manufacturers, starting with Fiat used two widely spaced spring mounts.
A beam axle's location in the fore and aft directions is constrained by one of several suspension components, including trailing arms, semi-trailing arms, radius rods, and leaf springs. The lateral location can be constrained by a Panhard rod, a Scott Russell linkage, a Watt's linkage, or some other arrangement, most commonly by the leaf springs.
