Abstract (Croatian)

Izrada vozila na električni pogon od samih početaka činila se kao jako zanimljiv projekt. Konačni cilj izrade električnog romobila bio je taj da, osim sigurne i udobne vožnje, njegova maksimalna brzina bude barem 30km/h, a autonomija vožnje približno 10 kilometara. U konačnici, rezultati su bolji od predviđanja, pa se tako najveća brzina penje čak do 43km/h, a autonomija do oko 15 kilometara. U ovom radu detaljno je opisana mehanička konstrukcija i njeno modeliranje u CAD programu, izvršeni su proračuni naprezanja i maksimalne moguće opteretivosti konstrukcije te je izabran osnovni metalni profil za konstrukciju. Motor koji pogoni romobil teži samo 1.2kg, a maksimalna snaga koju daje je 2400W što je daleko iznad većine kineskih vozila na električni pogon ovoga tipa. Tiskane pločice crtane su na računalu, a cjelokupnim sustavom upravlja sićušni mikrokontroler pod nazivom ATmega328P. On je programiran tako da ima nekoliko izbornika koji prikazuju različite podatke, a moguće je mijenjati čak i režim vožnje električnog romobila. Romobil je opremljen prednjim i stražnjim osvjetljenjem potrebnim za noćnu vožnju. Vozilo ovoga tipa moguće je voziti bez registriranja, ako se vozi isključivo u „economy“ režimu vožnje, a vožnja kao takva je jednostavna i sigurna zbog robusne konstrukcije, amortizera, disk kočnica i dobro programiranog sustava za upravljanje motorom.

Abstract

From the beginning, the idea of making an electrically propelled vehicle seemed to be a very interesting project. The ultimate goal was to make a safe and comfortable vehicle, with a maximum speed of at least 30km/h and with range of 12 kilometers. Ultimately, the results were even better than predictions so the top speed climbs up to 43 km/h and the autonomy is about 15 kilometers. In particular, this seminar contains detailed descriptions of the mechanical design and it's modeling in a CAD program. Also, the calculations of strainings and maximum possible load capacity of the structure were carried out and the basic metal profile for the construction was chosen. The engine of the scooter weighs only 1.2kg and the maximum power that it gives is 2400W, which is far above all Chinese electric-powered vehicles of this type. Printed circuit boards were drawn on the computer and the entire system is controlled by a tiny microcontroller called the Atmega328. It is programmed in such a way that there are several menus that display different data and it is even possible to change the driving mode of electric scooter. Scooter is also equipped with front and rear lighting needed for night driving. This vehicle is drivable without registering if you drive exclusively in "economy" mode driving. Also, driving is easy and safe due to robust construction, shock absorbers, disc brakes and well programed engine management system.
