Abstract

Različiti momenti utječu na vozilo u kretanju: moment uzrokovan otporom zraka, moment uzrokovan kotrljanjem, moment uzrokovan nagibom puta, dinamički moment i statički moment. Mjerač momenta ugrađen je na pogonski kotač vozila, instaliran je sustav za mjerenje i mjeren je moment i brzina vrtnje. Pomoću akvizicijske kartice u vozilu izmjereni su struja i napon baterije. Dobiveni rezultati su prikazani u grafovima i analizirani. Izračunata je korisnost prijenosa snage. Uspoređena su mjerenja s onima provedenim dok je u vozilu bio motor s unutarnjim izgaranjem. Opisan je način rada uređaja za mjerenje momenta na kardanskoj osovini i napravljene su upute za njegovo korištenje.

Abstract (english)

Different torques are affecting the vehicle in motion: torque caused by air resistance, torque caused by rolling, torque caused by slope of the base, the dynamic torque and static torque. Torque measurer is installed on the drive wheel of the vehicle, system for measuring is installed, torque and speed are measured. Using the acquisition card in the vehicle current and voltage of battery were measured. The results are shown in graphs and analyzed. The efficiency of power transmission is calculated. Measurements were compared with those conducted in the car while it was powered by internal combustion engine. Measurer for measuring torque on the rotating axle is described and the instructions for its use are made.
