本发明涉及一种电动气动手制动系统(10),用于具有弹簧加载的制动器的车辆,该电动气动手制动系统包括:气动继动阀(11);双稳态螺线管阀(12),以控制所述继动阀(11);以及控制单元(46),以控制所述双稳态螺线管阀(12),其中,所述继动阀(11)的出口连接到用于所述弹簧加载的制动器的端口(18),并且其中,所述双稳态螺线管阀(12)的入口被设置成用于连接到承载通气压力的管线(22),所述电动气动手制动系统(10)进一步包括设有控制输入端的自固位切换阀,其被设置在所述双稳态螺线管阀(12)的所述入口之前,其中,a)当在其控制输入端处有足够的压力时,所述自固位切换阀(13)可以抵抗恢复元件的力从阻塞位置移动到通流位置,并且b)所述自固位切换阀(13)的出口连接到所述双稳态螺线管阀(12)的所述入口,并且c)所述自固位切换阀(13)的所述控制输入端还连接到信号线路,经由所述信号线路,可以至少在短时间内将信号压力作为控制压力馈送到所述控制输入端,并且d)所述自固位切换阀(13)在其通流位置将其出口与其入口连接,并且e)所述自固位切换阀(13)在其阻塞位置将其出口(25)与放气出口连接。
An electro-pneumatic hand brake system is for a vehicle with spring-loaded brakes. The system includes a pneumatic relay valve, a bistable solenoid valve for controlling the relay valve and a control unit for controlling the bistable solenoid valve. An outlet of the relay valve is connected to ports for the spring-loaded brakes. An inlet of the bistable solenoid valve is provided for connecting to a line carrying ventilation pressure. A self-retaining switching valve with a control input is provided before the inlet of the bistable solenoid valve. The self-retaining switching valve can be moved against the force of a restoring element from a blocking position into a flow-through position when there is sufficient pressure at its control input. An outlet of the self-retaining switching valve is connected to the inlet of the bistable solenoid valve.
