Estudo sobre a substituição de feixe de molas por um sistema coilover em um Chevrolet Corvette

Abstract

The objective of this work is to analyze the replacement of the rear leaf spring suspension with a coilover system, along with the substitution of the rear suspension with a four-link setup in a Chevrolet Corvette C1, with the goal of enhancing the vehicle's drivability, performance, and comfort. The rear leaf spring suspension is advantageous for cargo transport and has a low maintenance cost. However, to achieve a balance between comfort and performance, the decision was made to replace it with a coilover system. The coilover provides a significant improvement in the trade-off between performance and ride comfort. Nevertheless, this replacement necessitates modifications to the suspension, as the original leaf spring is integral to supporting the rear axle. Additionally, the cost of replacement and maintenance is higher. To facilitate the replacement of the suspension damping system, a modification of the original suspension system was required. Thus, the rear suspension was exchanged for a four-link setup. This modification optimizes weight transfer during longitudinal movements and enhances traction on the driving wheels. The four-link system offers greater control, stability, reduces body roll in corners, and ensures better contact of the tires with the ground. [resumo fornecido pelo autor]
