Beschreibung
Zusammenfassung:	FIELD: mechanical engineering. ^ SUBSTANCE: transmission comprises pump station provided with the pressure-tight hydraulic tank, high-pressure tank, make-up pump, and hydraulic motors for driving wheels. The hydraulic motors are in communication with the pump station through hydraulic pipelines that define a circulating hydraulic circuit. The by-pass hydraulic lines connected with the main hydraulic lines receive relief valves provided with a valving member. The drain hydraulic line receives the pilot valve controlled by means of the fluid pressure gage in the supplying hydraulic line and pressure gage of compressed air in the pneumatic system. The friction clutch has a fluid-pressure drive for its disconnecting which is set in operation by the valve for supplying compressed air and is controlled by means of temperature transducer and pickup of the level of the fluid in the hydraulic tank, air pressure gage in the air space of the hydraulic tank, and pickup of position of the valving member of the shut-off valve mounted in the sucking hydraulic line of the make-up pump. ^ EFFECT: enhanced reliability. ^ 3 cl, 2 dwg
