ASSESSMENT OF THE INFLUENCE OF THE COEFFICIENT OF FRICTION ON THE TEMPERATURE DISTRIBUTION OF A DISC BRAKE DURING THE BRAKING PROCESS

Brake assemblies are key mechanisms in the aspect of safe and reliable operation of devices and machines. Due to intense thermal processes that occur during braking, the brakes are exposed to an accelerated wear. The article assesses the impact of tribological cooperation conditions between the caliper and the disc of a disc brake on the temperature of a disc. The variable value in the simulations was the coefficient of friction between the cooperating surfaces. A direct effect of the increase of the analysed parameter on the enhancement of brake elements’ temperature was found. At the same time, a similar nature of thermal processes was observed for all values of the friction coefficient taken into account.
