The invention relates to a trailer control module and a trailer control valve arrangement. A trailer control module (1) for an electropneumatic brake system (100) comprises a trailer control valve arrangement (TCV) (20) connected at least to a supply connection (2) for receiving a supply pressure (pS) and providing a trailer control pressure (pTC) to a trailer working port (6), the TCV (20) comprising a shut-off valve unit (26), and a relay valve unit (30) for switching between a supply state enabling fluid communication between the supply connection (2) and the relay valve unit (30) and a disconnected state for throttling said fluid communication. The cut-off valve unit (26) comprises a switching member (54) which is subjected to a first pressing force F1 defined by the pilot control pressure (pPC) and a counteracted second pressing force F2 defined by the trailer control pressure (pTC), where the switching member (54) switches to the cut-off state in the event that the second pressing force F2 falls below a predetermined threshold value TB.

    本发明涉及一种挂车控制模块和挂车控制阀装置。用于电动气动制动系统(100)的挂车控制模块(1)包括挂车控制阀装置TCV(20),该TCV(20)至少连接到供应连接件(2)用于接收供应压力(pS)并向挂车工作端口(6)提供挂车控制压力(pTC),该TCV(20)包括断开阀单元(26),用于在使得供应连接件(2)和中继阀单元(30)能够流体连通的供应状态和用于节流所述流体连通的断开状态之间切换。断开阀单元(26)包括切换构件(54),该切换构件受到由先导控制压力(pPC)限定的第一挤压力F1和由挂车控制压力(pTC)限定的抵消的第二挤压力F2,其中在第二挤压力F2下降到低于预定阈值TB的情况下,切换构件(54)切换到断开状态。
