Abstract
The accident-free and safe operation of lifting and transporting machines largely depends on the reliable operation of the friction pairs of brake devices. The experience of operating has showed that the wear-friction characteristics of the friction pairs materials depend mainly on their thermal regime, and primarily on the degree of heating of the surface and near-surface layers of the friction materials. The creation of more efficient lifting and transporting machines with unit capacity increase the energyloading of the friction pairs of the brake devices installed on them, which means that the heating of the elements of the friction pair increases at the same time. In this publication, the following issues are considered in relation to the problem being solved: requirements and conditions that ensure the operable state of a multi-jet ejector cooling system; design and operation of a multi-jet ejector cooling system for friction pairs of the disk brake. The aim of the work was to improve the wear-frictional properties of friction pairs of the disk brakes by reducing their energyloading.
