FIELD: machine building.
SUBSTANCE: present invention relates to braking system (10, 10', 10'') for a truck, in particular to a hydraulic and/or pneumatic braking system (10, 10', 10'') for truck, at least, with parking brake device (12, 12', 12'') and, at least, with additional hydraulic and/or pneumatic module (14, 14', 14''), wherein valve (20, 20', 20'') high pressure bleeding and brake cylinder (22, 22', 22'') with spring-loaded power accumulator, wherein parking brake device (12, 12', 12'') is connected by first connecting pipeline (24, 24', 24'') with high pressure bleeding valve (20, 20', 20'') on its first inlet (20a, 20a', 20a''), wherein hydraulic and/or pneumatic module (14, 14', 14'') is configured to be connected by second connecting pipeline (26, 26', 26'') with high pressure bleeding valve (20, 20', 20'') to its second inlet feed (20b, 20b', 20b''), wherein brake cylinder (22, 22', 22'') with spring-loaded power accumulator is connected by third connection pipeline (30, 30', 30'') with high pressure bleeding valve (20, 20', 20'') on its outlet feed (20c, 20c', 20c'') and wherein in second connecting pipeline (26, 26', 26'') distribution valve (18, 18', 18'') is installed, by means of which pneumatic module (14, 14', 14'') in first switching position of distributing valve (18, 18', 18") is not connected to high pressure bleeding valve (20, 20', 20"), and at least in second switching position of distribution valve (18, 18', 18") is connected to high pressure bleeding valve (20, 20', 20'').
EFFECT: invention provides excessive safety of braking systems, in particular parking braking devices for trucks, and additionally increases safety of operation of braking system.
