description: The steering system is important for vehicle safety because the driver turns the steering wheel to control the steering system and thus change the direction of the vehicle. The plain bearings are an important part of the steering system. Improving the lubrication of the plain bearings can effectively improve the performance of vehicle steering. In this work, the steering system and the position of the plain bearings were modelled using Pro/E (Pro/Engineer) 3D modelling software. Torque and friction coefficient measurements showed that the modifier reduced the friction torque by 15.69 and the friction coefficient by 0.069 compared to the MS-20 base oil. Measurements of the total contact temperature of the friction substrate showed that it was 32Â°C lower compared to the MS-20 base oil (134Â°C). Weighted wear measurements showed that there was instability and variation in the experimental results when tested with the modifier in the oil. Measurements of the surface profile and roughness parameters of the roller and pad specimens showed a decrease in Ra of 0.064 Âµm during the test. Metallographic investigations were carried out on the wear areas before and after the test. Separate areas of copper-containing protective film were found on the surface of the rollers on specimens tested in oil MS-20 with the addition of Senreco composition. Analysis of all the experimental data allowed us to conclude that in friction with a modifier, the protective film is formed in the contact area after 50-60 minutes after the start of the test and then begins to abrade.
