Summary:

The study aims to evaluate the energy-transforming properties of the braking control of vehicles (cars). The article presents the functions that are an integral indicator characterizing the conversion of energy in braking mechanisms and braking system as a whole during single braking. Representation of these functions in a differential form allows a quantitative assessment of energy conversion at any given time. Taking into account the changes in the kinetic energy of a vehicle during braking and the work spent on turning on the braking mechanisms, the equation of the energy transfer function for the braking mechanism of the jth axis during single braking is obtained. The dependence diagrams of the energy transfer function in differential form for disk braking mechanisms of a passenger car of segment C and drum braking mechanisms of cars with a total mass of 11 tons and 20 tons are presented. The time dependence diagrams from various initial speeds of the relative friction power during the braking of the car are given. Tests have shown that disk brakes have high stability regardless of geometric and thermal running-in, while drum brakes are very sensitive to high thermal loads and require good thermal running-in of friction linings
