In the article, the measures aimed at preventing vibrations generated in the wheel motor unit, one of the main most responsible units of mainline locomotives, are mentioned. There are different types of gears in the wheel motor unit, and the additional vibration is higher in the gear wheels of the assembled form. Because the gears of this assembly form are made of resinotechnical materials. This suspension element is made of V14 rubber technical material. The original purpose of the article is to use synthetic nitrite rubber SKN-18M instead of V14 rubber technical material based on local standards. It was studied that by changing the ingredients in SKN-18M and the sequence of their addition, it is possible to obtain a detail with improved vibration resistance and load bearing capacity. It was found that the amount of carbon-rubber gel and the vulcanization network of the material increased, the vulcanizate swelling level decreased, which is mainly due to the presence of oligomeric components on the surface of carbon particles. It is shown that the inclusion of this raw material in elastomeric compositions based on butadiene nitrile rubber increases the interaction at the “rubber-filler” boundary and the formation of additional bonds between rubber macromolecules and functional groups of the oligomer, and as a result, the overall technological and technical properties of the compositions are improved.
