Hydraulic Transmission Systems in Agricultural Technics

Abstract

Current development of agriculture is being determined with research and implementation of new technologies and modern technical appliances which will be able to provide quality and economically approved application for all technological operations all mentioned, with the least possible consumption of energy and human resource and engagement, as well as to achieve environment preservation, and provide healthy working conditions. One of the most important matters, from the aspect of usage and market value of agricultural machinery and the others working machines, is the choice of propulsion. Mechanical power transmission does not satisfy newly established conditions for changes in output parameters, or these solutions are becoming too complex and expansive. Therefore, power transmission in agricultural technics is often based on hydraulic transmission systems. In this work will be presented new solutions for hydrostatical and hydrodynamical power transmission, and applycability analysses of connection between electric motor and internal combustion engine with turbojoints and turbotransmiters.

Današnji razvoj poljoprivrede karakteriše osvajanje i primena novih tehnologija i savremenih tehničkih sredstava koja će obezbediti kvalitetno i ekonomski opravdano obavljanje predviđenih tehnoloških operacija, uz što manji utrošak energije, ljudskog rada i vremena, očuvanje okoline i obezbeđenje humanih uslova za rukovaoce. Izbor vrste pogona poljoprivrednih mašina predstavlja značajno pitanje koje utiče na upotrebnu i tržišnu vrednost mašina. Mehanički prenosnici snage ne zadovoljavaju sve strožije zahteve za promenom izlaznih parametara ili ova rešenja postaju komplikovana i skupa. Zbog toga se savremeni razvoj prenosa snage u poljoprivrednoj tehnici sve više bazira na hidrauličkom prenosu snage. U radu će biti prikazane varijante hidrostatičkog i hidrodinamičkog prenosa snage i analiza pogodnosti povezivanja elektromotora i motora SUS sa turbospojnicama i turbomenjačima.
