ELECTROPNEUMATIC HANDBRAKE (EPH) HAVING A PARTIALLY DECOUPLED TCV (EUROPEAN ACTUATION)

摘要

The invention relates to an electropneumatic control module (1) for an electronically controlled pneumatic brake system for a vehicle having a towing unit and a trailer. The electropneumatic control module (1) has a pneumatic supply port (3), which can be connected to a compressed air supply (3a), and a vent port (4), which is connected to a vent (5), a trailer control unit (TCV), which has a trailer control valve unit (8), a trailer brake pressure port (22) and a trailer supply pressure port (21), a handbrake unit (EPH), which has a spring reservoir port (6) for at least one spring reservoir brake for a towing unit and a handbrake valve unit (10), and an electronic control unit (ECU) for controlling the trailer control valve unit (8) and the handbrake valve unit (10). Also provided is a check valve (20), which is arranged between the trailer control unit (TCV) and the handbrake unit (DPH) for the at least partial decoupling of the trailer control unit (TCV) and the handbrake unit (EPH).
