Abstract

Ovaj završni rad bavi se preinakom serijskog osobnog vozila u vozilo za sudjelovanje na rally natjecanju, konkretno u kategoriji FIA R4 Class. Rad uključuje analizu općih zahtjeva FIA pravilnika za konstrukciju vozila gdje se navode općenita pravila, detalji vezani za motor, transmisiju, ovjes i aerodinamiku. Nadalje, detaljno se razmatra konstrukcija zaštitnog kaveza i njegovo pozicioniranje unutar putničkog prostora vozila. Zaštitni kavez je ključni sigurnosni element, a njegova konstrukcija mora zadovoljiti visoke standarde sigurnosti propisane FIA pravilnicima. Dio rada posvećen je analizi komponenata ovjesa koje su dopuštene prema pravilima natjecanja. Ovjes je ključan za performanse vozila u rally uvjetima jer utječe na trakciju, stabilnost i upravljivost. Ovdje se razmatraju optimalne konfiguracije ovjesa i smještaj komponenata kako bi se postigla vrhunska vozna dinamika i kontrola. Za kraj napravljen je koncept vozila koji sjedinjuje trkaće komponente i u cjelini čini rally vozilo.

Abstract (english)

This final work deals with the conversion of a series passenger vehicle into a vehicle for participation in a rally competition, specifically in the FIA R4 Class category. The paper includes an analysis of the general requirements of the FIA Regulations for vehicle construction where general rules, details related to the engine, transmission, suspension and aerodynamics are specified. Further, the construction of the protective cage and its positioning within the passenger compartment of the vehicle is considered in detail. The protective cage is a key safety element, and its construction must meet the high safety standards prescribed by THE FIA regulations. Part of the paper is devoted to the analysis of suspension components that are allowed according to the rules of competition. Suspension is crucial for vehicle performance in rally conditions as it affects traction, stability and handling. Optimal suspension configurations and component accommodation are considered here to achieve superior driving dynamics and control. For the end, a vehicle concept was made that unites the racing components and as a whole makes the rally vehicle.
