U radu je izvršena analiza bilansa snage u zaokretu za tipične predstavnike simetričnih i nesimetričnih sistema za zaokret sa dva toka snage. Na osnovu analize aktivnih sila i brzina premotavanja gusenica u funkciji od poluprečnika zaokreta, dobijene su potrebne snage na gusenicama za realizaciju zaokreta u zadatim uslovima. Za svaki sistem za zaokret definisana su funkcionalna stanja i tokovi snage u svakom od njih. Izvršena je uporedna analiza bilansa snage u zaokretu za simetrični i nesimetrični sistem sa istim performansama pravolinijskog kretanja radi sagledavanja uticaja kinematske šeme na vučne performanse. Pokazano je da kinematska šema sistema za zaokret znatno utiče na vučne performanse zaokreta i da kod simetričnih sistema postoje veći gubici snage i veća potreba za snagom motora. / The analysis of turning power balance for symmetric and nonsymmetrical turning systems of tracked vehicles has been considered in the paper. The necessary power of tracks for required radius of turn has been determined on the base of analysis of active forces and track velocity accordance to radius of turn. Functional conditions and power flow have been defined for each turning system. The comparative analysis of turning power balance for symmetric and nonsymmetrical turning system with equal tracked performances has been fulfilled and the influence of kinematic scheme on turning tracked performances has been explained. The analysis has showed influence of kinematic scheme on turning tracked performances. The symmetric turning systems worked with higher power losses hence the higher power of vehicle engine is required.
