Mechanism of Particles Released into the Environment That Is Formed by Brake Wear on Friction Surfaces

Abstract

Solving the problem of the formation of particles caused by the wear of the brakes’ friction surfaces and their release into the environment is of utmost importance. Today, various technologies have been developed that aim to collect particles directly during braking or generation. With the aim of further development of devices and technologies in this paper, the modes and mechanisms of release of the formed particles into the environment are analyzed. Based on this review of the particle release mechanisms, further development of technologies for collecting particles that are a product of friction surface wear is enabled. The mechanisms of particle release are mainly reflected in the fact that they are released during the braking of the vehicle, then by releasing particles during the re-acceleration of the vehicle and the third way is falling of already formed particles from friction surfaces. In this paper, all three mechanisms are explained and analyzed in more detail.
