Abstract
A comparative analysis of the performance of various brake friction linings with functional properties. Friction brake linings of the code TIIR and JSC AZ URAL produced in the Russian Federation and TRIBO produced in the Ukraine, which are widely used in the brakes of Ural vehicles, were subjected to bench tests. A comparative analysis of the performance of these materials and asbestos-free friction composites patented in Republic of Armenia and the Russian Federation with functional properties of the Bastenite type, created in the basic research laboratory “Tribology” of National Polytechnic University of Armenia, was carried out. As a result of bench tests on the operational simulated operating parameters of drum brakes of dual-purpose vehicles "Ural", it was found that in terms of braking efficiency, braking efficiency loss and recoverability parameters, the material of the Bastenit-9 type provides the necessary performance and meets the requirements of the international standard SAE J 661 201211. In terms of wear resistance, the material of the Bastenit-9 type is superior to its analogues. To organize the production of friction materials of the Bastenit type in Republic of Armenia, it is proposed to conduct joint road tests with interested organizations of the Russian Federation and Republic of Armenia.
