The paper considers braking process of mine diesel locomotive with hydrostatic mechanical transmission (HSMT) operating according to “input differential” scheme. Braking process is modeled in terms of kinematic motor disconnection from wheels under maximum possible braking moments on wheels.Showing up and systematizing of basic regularities concerning the distribution of power flows within closed transmission contour in the process of braking have been implemented with the help of software support developed by means of MatLab/Simulink. The simulation results of braking due to the hydrostatic transmission and the braking system during the movement of a diesel locomotive in the transport and tractive ranges are presented in the form of graphical dependences. It has been determined that when a kinematic disconnection of a mechanical branch takes place within the closed loop of HSMT No. 1 by means of a clutch, neither ascent/descent angle nor net tractive effort of mine diesel locomotive effect significantly the distribution of kinematic, power, and energy parameters of the HSMT.
