20.500.12556/RUL-149165 Analiza delovanja TORSEN diferenciala vgrajenega v VW Passat Analysis of the operation of the TORSEN differential installed in the VW Passat V diplomski nalogi je najprej predstavljena vloga diferencialov v motornih vozilih. Nato so predstavljeni osnovni principi delovanja in konstrukcija klasičnega mehanskega diferenciala. Podrobneje je predstavljen TORSEN diferencial ter njegova konstrukcija in princip delovanja polževih gonil. Za obravnavani TORSEN diferencial je potrebno določiti geometrijske izmere zobnikov. S pomočjo opravljenih praktičnih meritev je potrebno določiti koeficient trenja in izkoristek diferenciala. Koeficient trenja smo določili na dva načina - najprej po preprostem preračunu s pomočjo enostavnega preizkusa, ter nato še preko kompleksnejšega ter bolj natančnega preračuna. Ustreznejši rezultat smo dobili preko kompleksnejšega izračuna – koeficient trenja je znašal 0,109. Na koncu naloge smo določili generirano toploto v diferencialu zaradi vožnje v ovinku, kjer smo predpostavili čas vožnje ter dva različna radija ovinka. Računsko določena generacija toplote je bila presenetljivo majhna – diferencial se je najbolj segrel v primeru vožnje z maksimalno močjo motorja v ovinku z manjšim radijem, in sicer za 2,7°C. The bachelor's thesis first presents the role of differentials in motor vehicles. Next, the basic operating principles and construction of a conventional mechanical differential are presented. Furthermore, the TORSEN differential is presented in more detailed way, as well as its design and principle of worm gears operation. For the discussed TORSEN differential, it is necessary to determine the geometric dimensions of the gears. With the help of practical measurements, it is necessary to determine the coefficient of friction and the efficiency of the differential. We determined the coefficient of friction in two ways - first by a simple calculation using a simple experiment, and then by a more complex and more accurate calculation. A more appropriate result was obtained through a more complex calculation - the coefficient of friction was 0.109. At the end of the thesis, we determined the heat, that is generated in the differential due to driving in a corner, where we assumed the driving time and two different corner radius. The calculated heat generation was surprisingly small – the differential heated up the most in the case of driving with maximum engine power in a corner with a smaller radius, namely by 2.7°C. prenos moči polževa gonila TORSEN diferencial samozapornost gonila koeficient trenja power transmission worm gears TORSEN differential self-locking drives friction coefficient true false false [A.
