Abstract

Mjerač momenta i brzine vrtnje na kardanskoj osovini električnog automobila je sustav kojeg čine odašiljački i prijemni modul, baterijsko napajanje, tenzometar i magnetski senzor blizine. Tenzometarski most tijekom deformacije osovine mijenja otpor i daje izlazni naponski signal koji ide na mjernu elektroniku. Brzina vrtnje osovine se mjeri brojanjem impulsa pomoću magnetskog senzora blizine koji svaki okret bilježi kao jedan impuls. Prijemni modul koji se napaja sa 12 V daje na izlazu dva strujna signala 4-20 mA koji predstavljaju moment i brzinu vrtnje pa je onda moguće izračunati snagu na kardanskoj osovini koja je umnožak ta dva signala.

Abstract (english)

A torque and angular velocity measuring system which is used on an electric car cardan axle is made of a transmitting and receiving module, battery power supply, strain gage and a magnetic proximity sensor. A strain gage bridge changes its resistance during axle deformation and gives an output voltage signal to a measuring circuit. Angular velocity is measured by counting impulses from a magnetic proximity sensor which gives one impulse per turn. A 12 V receiver module gives two current output signals (4-20 mA) representing the torque and angular velocity. Iti s possible to calculate the power on a cardan axle as a product of these two signals.
