FIELD: machine building.
SUBSTANCE: invention relates to transport machine building. Device of electric parking brake for vehicle comprises parking brake valve system and a brake cylinder with a spring-loaded power accumulator, which is intended for connection through a supply pipeline and valve system of the parking brake with a compressed air source, which in the parking brake device off state is loaded with the compressed air source pressure through the parking brake valve system, and in the parked device position the parking brake is connected to the pressure reducer via the parking brake valve system. Valve parking brake system is designed for electropneumatic control in order to initiate off or on state in first operating mode. Valve system of parking brake contains a muscular-actuated control element and is intended for pneumatic control using a muscle-actuated control element for switching on or off state in the second operating mode.
EFFECT: reliable parking or breakdown of a truck in case of power failure.
