mining machine building. SUBSTANCE: invention is related to design of hydraulic systems of drive of undercarriage of mining machines. System of control over transmission of track-laying mining machine includes motor, kinematic chain with gear transmission and driving shaft, friction clutches, braking cams, hydraulic cylinders controlling friction clutches with spring-loaded cavities, pushers and rod spaces, unbraking hydraulic cylinders with piston spaces and pistons, feeding pump, hydraulic distributor, control pump, pressure valve, safety valve and pressure lines. Spring-loaded cavities of hydraulic cylinders controlling friction clutches are continuously connected to pressure line of control pump. EFFECT: provision for automatic and instant fixing of mining machine, its increased reliability and safety. 1 dwg
