Abstract

The paper describes the approach for the evaluation of predesign-thermal load of the braking mechanism for vehicles with anti-lock braking systems (ABSs). The main essence of which is that most of the kinetic energy of the car with ABS is extinguished by friction in the brake mechanism. Overheating of the brake mechanism, namely its friction pairs, leads to the phenomenon of critical fading, accompanied by a sharp decrease in the braking torque. A method is proposed for determining the energy quenched in a braking mechanism with ABS using three approaches. The main of which is the ratio of the longitudinal reaction and the braking torque associated with the dynamic radius of the wheel. Since the rotation speed of the wheel of car with ABS during braking varies according to a complex law. Finding the path of friction as a component of the energy balance is based on the linearization of the speed function. Finding the extinguished energy is necessary for carrying out thermal calculation of details of brake system including with the use of a method of finite elements. The study was the basis for creating a computer model of the temperature field of the braking mechanism, which, on the whole, makes it possible to talk about a system for calculating the thermal loading of braking mechanisms with ABS.
