heal.abstract	The motivation of writing this thesis is an effort to design a suspension system, which passively controls the wheel’s Camber angle in an optimum way, in order to improve the performance of the vehicle and provide a solution to the known compromises of traditional suspension layouts. The idea is based on the use of a secondary chassis, which is placed between the main chassis and the wheel of the vehicle. This secondary chassis which is called a “Subframe”, while being connect with an appropriate mechanism to the chassis, with specific geometric characteristics, has the ability to identify a lateral force acted on the vehicle’s axle and roll in the opposite direction of the main chassis. The result is that the “Camber Loss” phenomenon is addressed during the roll motion, while also the vehicle’s tyre behaviour is improved during heave motion. This thesis begins with an explanation of the basic principles of a traditional vehicle’s suspension system and the vehicle’s tyres working mechanism. It is crucial to mention that the baseline for the application and any comparison is the single-seater car “P20”, which is designed and manufactured by the Formula Student Team “Prom Racing” from the National Technical University of Athens. After the initial case presentation, an analysis of the proposed suspension layout is done with mathematical formulas, as well as with a simple finite elements model to validate the results. In order to prove the functionality of the concept, the application of the geometry is presented for a Formula Student vehicle and the process of choosing the desirable values, to achieve the expected result. The application is supported by conceptual designs using CAD as well as calculations of the loads that are applied on the structure. In the final chapter, there is a quantified comparison between the proposed geometry and the traditional Double Wishbone geometry of the vehicle P20, and the performance gain is directly calculated.	en
