FIELD: railway transport; automatic parking brakes.
SUBSTANCE: stopping of action of automatic parking brake during period of charging of automatic brake with unexhausted operating part till moment of completion of release of the latter comes to prevention of communication of setting complex of automatic parking brake with brake main line. Required pressure level of compressed air in operating part of automatic brake is built in two steps. At first step, initial pressure level of compressed air is provided. For this purpose braking of control part of automatic brake is effected and then, during second step, isolation of control part from operating part and charging of the letter with compressed air from brake line to gauge pressure level are carried out. Charging is stopped after adequate level of compressed air pressure is obtained. Device is furnished with setting up and fixing complexes which interact with automatic brake and additional pneumatic meter.
EFFECT: provision of guaranteed remote stopping of action of automatic parking brake irrespective of tightness of operating and control parts of automatic brake and spread of pressure levels of compressed air.
