Abstract

The paper examines the operation of Van Hool 915 Acron and NEOPLAN N31 6 / 3UL buses involved in long-distance domestic and international transportation. Due to the conducted research, the consumption of fuel and lubricants was found to increase up to twenty percent in relation to passport data. The technical and economic feasibility of reconstruction of transmission units by replacing a pair of gears is proved, in particular the replacement of secondary shafts gear by a smaller one and intermediate shafts gear by a bigger one. Such replacements allow to increase the gear ratio of the crankshaft and reduce the consumption of fuel and lubricants. Van Hool 915 Acron passenger buses (engine D2866 LOH29 MAN, volume 11967.00 cm³, power 280 kW, diesel, compliance with Euro-3 environmental standards) and NEOPLAN N316 / 3 UL (engine MAN 2866 LOH 29 volume 12000cm³, power 280 kW, diesel, compliance with Euro-3 environmental standards) were selected for the study, which provide 80% of transportation at the company of Stetsyk T.V. During the study, the improvement of transmission by upgrading the mechanical eight-speed gearbox ZF 8s180 was substantiated, resulting in improved speed characteristics and fuel economy. The efficiency of the improved transmission has been tested in practice on the routes Ternopil-Kyiv, Ternopil-Kharkiv, Ternopil-Zaporizhia, Ternopil-Szczecin, Ternopil-Slupsk, Ternopil-Kolbzheg. The minimum and maximum economy of fuel and lubricants is considered in the article, as well as the payback period of such unification on the most profitable and least profitable routes in terms of the number of passengers transported routes. Based on calculations and practical research, the carrier confirmed the feasibility of upgrading the gearbox ZF 8s180 on buses Van Hool 915 Acron and NEOPLAN N316 / 3 UL. In the article, the authors prove that vehicles operating on international routes, where the highway is predominant, should be modernized first and foremost.
