Abstract

The article describes two main approaches to assessing the thermal loading of friction pairs—experimental and theoretical for evaluating friction pairs in terms of the phenomenon of fading. Most of the kinetic energy of a car with ABS is extinguished due to friction in the braking mechanism. Overheating of the brake mechanism, namely, its friction pairs, leads to the occurrence of critical fading, accompanied by a sharp decrease in braking torque. Reducing the influence of this phenomenon is a very difficult task both from the point of view of taking into account the cost of the brake mechanism and its minimal complexity. The authors propose the use of cryogenic treatment of brake discs to reduce the influence of thermal stress on the occurrence of fading, as well as comparing the results of theoretical and experimental evaluation of friction pairs of the brake mechanism. Modern methods of calculating temperature values and obtaining experimental data have been applied, allowing one to increase the accuracy of thermal load estimation.
