DESIGN SOLUTIONS OF THE TASK OF PROTECTION OF VEHICLES

Ovim radom obuhvaćena je zaštita podvozja i općenita zaštita na vozilima posebne namjene. Pružen je kratki osvrt na postupke korozije i na mehanizme djelovanja korozije. S obzirom da se radi o grani autoindustrije fokusiranoj na teška vozila, tako je i sama zaštita podvozja i nadogradnji zahtjevna. Tvrtka Flammifer koja je bila obuhvaćena u ovom radu specijalizirana je za nadogradnje za kamione i poluprikolice, počevši od same konstrukcije do zaštite i završnog lakiranja. Bazirana je na izradi vatrogasnih vozila gdje je sama nadogradnja izrađena od aluminija pa time već ima osnovnu zaštitu od korozije u pogledu izbora materijala. Fokus rada bio je na reparaturi poluprikolice gdje je bilo vidljivih oštećenja i produkata korozije i na njenom lakiranju koje je potrajalo zbog same veličine podvozja. Sva se reparatura vršila u pogonu Flammifer gdje je cijela poluprikolica bila mehanički obrađena i lakirana te se izvršio i sam proces demontaže i montaže. Pojašnjen je i proces mehaničke obrade površine kao i proces lakiranja koji su obavljeni da bi se poluprikolica dovela u zadovoljavajuće stanje kako s aspekta funkcionalnosti tako i s estetičkog aspekta.In this thesis was included the protection chassis and the protection of some special-purpose vehicles. It was addressed about the process of corrosion and the mechanisms of action where corrosion works. Given that it is a branch of automotive industry focused on heavy vehicles so is the very protection of the chassis and vehicle upgrade demanding. The company Flammifer which has been covered in this thesis is a specialized in construction of upgrades for trucks and trailers to its final painting. It is based on the development of fire-fighting vehicles where the upgrade itself is made of aluminium and thus already has a basis corrosion protection in terms of material selection. Specifically focused on repairing trailers where there was visible damage and corrosion products, and thats the reason that the painitnig and reparing took so long due to the size of the chassis. . All repairs are carried out at the facility Flammifer where the whole trailer was mechanically processed and painted and the entire process of dismantling and assembling was also conducted. The process of mechanical surface treatment to the painting process was explained so that the trailer was brought to a satisfactory state, both in terms of functionalities and the aesthetic aspect
