This article is focused on the area of research and development of vehicles with electric drive. The paper presents the results of research based on real electric vehicle EDISON EV as the real traffic in laboratory conditions reflecting. The analysis of special driving style was created in order to increase electric vehicle range.

This article is about calculation of planetary gearbox. The gearbox consists of two planetary gears - input and output. The gearbox model is created in Simscape Driveline. The model contains Simscape blocks which represent a gear box, clutch, ideal torque source and many others blocks. At the end we compare our results of simulation with calculations.

This article deals with description of a diagnostic device used at the Department of Design and Machine Elements at the University of Zilina which has been built in order to measure, diagnose and evaluate gearbox faults by vibrodiagnostics. The article describes methods and damage creation process for tested gearboxes. Evaluation of different faults is also processed in this article as well as description of comparative measurements between real and artificially created pitting. Comparison of all measured data with SPM methods is also included.
