Composite sheet springs are not new to the automotive industry. In fact, the leaf spring itself goes back to the horse-drawn carriage. By design, leaf springs absorb vertical vibrations caused by road irregularities. Variations in spring deflection allow the potential energy to be stored as stress energy and then released more gradually over time. The compounds are well suited for applications with leaf springs because of their high strength-to-weight ratio, fatigue strength and natural frequency. The internal damping of the composite material leads to a better absorption of the energy of the vibrations inside the material, which reduces the transmission of vibration noise to neighboring structures. The biggest benefit, however, is the mass reduction: Compound blade springs are up to five times longer than a steel spring, so when General Motors (GM, Detroit, Michigan) switched to a cross blade Glass-reinforced epoxy compound In the 1981 Chevrolet Corvette C4, a single sheet spring, which weighed 8 pounds / 3.7 kg, replaced a ten-sheet steel system weighing 41 lb / 18.6 kg. This allowed GM to shave 15 kg / 33 lb unsprung Corvette weight, but maintain the same spring rates. The leaf spring was transversely mounted; That is, it ran across the width of the car on each axle. This eliminated coil springs that sit high up in a spring pocket in the frame. Therefore, the car can sit lower to the ground, which improves the handling of the car. Today, GM continues to employ GFRP composite sheet springs transverse to the front and rear of its Corvette models. The 2014 Chevrolet Corvette Coupe includes a double-wishbone suspension, which, in GM, goes by the name of short / long arm (SLA). SLA refers to the fact that the upper control arm is shorter than the lower one. A composite cross laminar spring presses against the lower arm and covers the width of the car. In fact, the spring is always loaded against the auxiliary frame. This design directs the shock loads on the side of the frame, eliminating the independent rear stabilizer bar that should be incorporated into the models with standard suspension packages. The curvature curve of the spring is also said to improve tire contact with the road during cornering. Compounds also have the potential to replace steel and save weight on longitudinal springs (see "Constructing a Stronger Long Spring" in "Editor Selections" on the upper right). These run parallel to the length of the vehicle, providing the suspension as an integrated part of the wheel guide system. "Longitudinal sheet springs have a greater safety factor," says Frank Fetscher, head of business development at Benteler-SGL (Ried, Austria), a joint venture of Benteler Automotive and the SGL Group - The Carbon Company (Wiesbaden, Germany, SGL Automotive Carbon Fibers opens a new plant in Washington, "under" Editor's Picks. ")" They may have a linear spring speed or a progressive spring - multi-stage springs - and should work better with respect to torsion and stiffness Lateral than the transverse springs ". |
