Razvoj elektronskega diferenciala za večsledno vozilo

Balantič, Jernej (avtor), Klemenc, Jernej (mentor)

V diplomski nalogi je obravnavana tema razvoja elektronskega diferenciala za večsledno vozilo z vgrajenimi elektromotorji v kolesih. Brez elektronskega diferenciala imajo vozila s kolesnimi elektromotorji tendenco poravnavanja, kar privede do slabše vodljivosti vozila, obrabe in dodatnega napora voznika. V sklopu diplomske naloge je bila izdelana numerična simulacija togih teles za prikaz teoretičnega delovanja elektronskega diferenciala. Prikazali smo navor na obeh elektromotorjih, električni tok na motorjih ter hitrost motorjev v zavoju. Predstavljena je programska koda za navorno krmiljenje elektronskega diferenciala na krmilniku Arduino. Za eksperimentalni del smo elektronski diferencial aplicirali na trikolesnik in izmerili minimalni obračalni krog, testirali občutek vožnje pri vozniku z vključenim in izključenim elektronskim diferencialom ter opravili preizkus spodrsavanja notranjega kolesa v zavoju. Rezultate smo medsebojno primerjali in jih komentirali ter podali mnenje o vplivu aplikacije elektronskega diferenciala in napotke za nadaljnje delo.

Izvleček

The thesis deals with development of an electronic differential for a multi- track vehicle with in-wheel electric motors. Without the use of the electronic differential vehicles have a tendency to straighten out, which leads to poor vehicle handling, wear and additional driver effort. Numerical simulation of rigid bodies were performed for estimating a theoretical operation of the electronic differential, in which torque on both motors, electric current of motors and speed of motors in a curve were measured. A program code for a torque-control differential on controller Arduino is also presented in this study. In experimental part of the study the electronic differential was tested in a three wheeler with measuring a minimal turning circle, a test- driver's feeling when driving with electronic differential turned on or off and with performing a test of inside wheel slipping when driving in a curve. The result were compared and commented. We also gave an opinion on the impact of using the electronic differential and developed plans for further work.
