Conveniences of Self-Propelling Chassis Appliance in Agricultural Mechanisation

Abstract

For a very long time, tractor development was a consequence of need for improvement. During this period, some important factors were neglected, like: energy consumption decrease, better quality of accomplishing agrotechnical quests, decrease of soil gauge, enhancement of agrotechnical characteristics, which all means creating basic drive machine with higher level of technical and economical validity. Self-propelling chassis have numerous advantages over classical tractor solution: very suitable placement of working machines and equipment, good maneuvering, improved pulling characteristics as a result of optimal distribution of weights and balasts on steering and driving wheels. In this work, a new solutions of designing a layout of self-propelling chassis have been presented, as well as comparison of characteristics of classical tractor and selfpropelling chassis. There is also shown an archetype of self-propelling chassis which is assigned in surface treatment and organisation of soil, dirt paths and passages for mobile irrigation systems.

Razvoj traktora u dugom periodu je bio vezan za njegova poboljšanja. Za to vreme, neki uticajni faktori su zanemarivani: smanjenje utroška energije, kvalitetnije ispunjavanje agrotehničkih zahteva, smanjenje gaženja zemljišta, poboljšanje agrotehničkih karakteristika, odnosno osvajanje rešenja osnovne pogonske mašine sa većim stepenom tehničke i ekonomske opravdanosti. Samohodni nosači oruđa poseduju niz prednosti u odnosu na klasično rešenje traktora: pogodan izbor mesta postavljanja radnih mašna, dobra sposobnost upravljanja, poboljšanje vučnih karakteristika, što je obezbeđeno pravilnom preraspodelom težina i opterećenja na pogonske i upravljačke točkove. U radu su prikazane mogućnosti komponovanja osnove šeme samohodnih nosača oruđa i uporedne karakteristike klasičnog rešenja traktora i samohodnog nosača oruđa. Prikazano je izvedeno rešenje (prototip) samohodnog nosača oruđa koje je namenjeno uređenju zemljišta po površini, zemljanih puteva i staza za kretanje mobilnih sistema za navodnjavanje.
