Abstract
Ovim radom napravljen je pregled uobičajenih izvedbi samoutovarnih traktorskih prikolica za drvene trupce tehničke kategorije R3 (zbroj najvećih tehnički dopuštenih osovinskih opterećenja prelazi 4500 kg, ali ne prelazi 21000 kg). Zatim smo definirali listu zahtjeva za samoutovarnu prikolicu i odabrani su projektni parametri zasnovani na analizi postojećih rješenja. Odabrano je najprikladnije rješenje prema kriterijima koji se odnose na eksploatacijske značajke, pouzdanost i proizvodnu cijenu. Samoutovarne traktorske prikolice su danas jedan od standardnih alata u eksploataciji šumskog dobra. Glavna namjena im je transport drvenih trupaca s mjesta sječe do stovarišnog mjesta koja služe kao međuskladište sirovine (drvenih trupaca) prije transporta do mjesta konačne prerade. Da bi se takvim specijaliziranim prikolicama mogao vršiti transport po teškom šumskom terenu ovi radom prikolica je dimenzionirana tako da su okvir i podvozje (osovine) robusne izvedbe i omogućuju dobro praćenje podloge po kojoj se vozni slog kreće (traktor i prikolica). Kako bi se povećala pokretljivost voznog sloga, na prikolicu je ugrađen dodatni pogonski sustav koji omogućuje da se po potrebi poveća broj pogonskih osovina voznog sloga. Odabrana varijanta rješenja je razrađena, te je izrađena tehnička dokumentacija.
Abstract (english)
In this thesis, a review of commonly designed self-loading tractor trailers for wooden logs in R3 technical classes (the sum of technically maximum permissible loads lies between 4500 and 12000 kg) has been represented. Afterwards, a list of demands for the self-loading tractor trailer has been defined altogether with chosen project parameters based on analysis of the existing solutions. Taking into the account criteria such as exploitation features, reliability and production cost, the most suitable solution has been chosen. Self-loading tractor trailers are nowadays one of the standard tools used in exploitation of forest goods. Their main purpose is the transport of wooden logs from harvesting location to warehouse location which is used as intermediate storage (of wooden logs) before transport to the location of the final processing stage. In order to complete a successful transportation on heavy forest ground with these specialized trailers, the trailer in this thesis is dimensioned in a way that the frame and chassis are robust and therefore enabling good tracking of the surface on which the assembly (tractor and the trailer) is moving. In order to achieve an increased movability of the assembly, an additional powertrain has been implemented in the design of the trailer which enables an additional number of shafts in the system, if necessary. The selected version of the solution has been elaborated and the supporting technical documentation has been presented.
