The invention relates to a compressed air brake system for a tractor. The compressed air brake system comprises two service brake circuits; a parking brake circuit (18) having a compressed air reservoir (52), a reservoir line (54) leading from the compressed air reservoir to the parking brake valve (20), and an axle brake line (56) leading from the parking brake valve to the spring-loaded brake cylinders (60a, 60b); the invention relates to a trailer control valve (22) having at least one direct control input (p41, p42) and a reverse control input (p43), a brake control line (82, 84) being coupled to the at least one direct control input and being coupled to a brake line (36, 46) of one of the service brake circuits, and a brake control line (86) being coupled to the reverse control input and being coupled to the brake line (36, 46) of the other of the service brake circuits. The brake control circuit is connected with a brake circuit (56) of the parking brake circuit; and a valve device (30) for controlling the foot brake valve-independent braking of the coupled trailer vehicle. The valve device has an electronically controllable valve unit (100) which is arranged in a brake control line coupled to a reverse control input of the trailer control valve. By means of the valve unit, a section of the brake control line on the trailer control valve side can be alternately connected to a section on the parking brake valve side or to the exhaust outlet.
本发明涉及用于牵引车的压缩空气制动设施,压缩空气制动设施具有:两个行车制动回路;驻车制动回路(18),驻车制动回路具有压缩空气储存器(52)、从该压缩空气储存器引导到驻车制动阀(20)的储备器线路(54)、以及从驻车制动阀引导到弹簧蓄能式制动缸(60a、60b)的车桥制动线路(56);具有挂车控制阀(22),挂车控制阀具有至少一个直接控制输入端(p41、p42)以及反向控制输入端(p43),其中,与至少一个直接控制输入端联接有制动控制线路(82、84),该制动控制线路与行车制动回路之一的制动线路(36、46)联接,与反向控制输入端联接有制动控制线路(86),该制动控制线路与驻车制动回路的制动线路(56)联接;以及具有阀装置(30),以用于对所耦联的挂车车辆进行的与脚制动阀无关的制动进行控制。阀装置具有电子可控的阀单元(100),阀单元布置在与挂车控制阀的反向控制输入端联接的制动控制线路中。借助阀单元,使得制动控制线路的在挂车控制阀侧的区段能交替地与在驻车制动阀侧的区段或者与排气输出端连接。
