Findings from the numerical study of the heat duty of an oil-cooled friction pair in a multidisk brake of a wheel tractor are presented. The boundary problem is formulated to describe the heat processes in an oil-cooled friction pair with radially positioned oil-control grooves under frictional heating. It is solved by the finite-element method for the case of the tractor’s braking on a protracted descent. The features of the temperature field formation in an oil-cooled friction pair are identified and a functional dependence of the maximum temperature on the friction contact surface on the coefficient of overlapping of the disc friction surfaces is obtained.
