The invention relates to a parking brake valve assembly (1) for an electronically controllable pneumatic brake system (210) of a utility vehicle (202), comprising: a first compressed air path (2) which receives a reserve pressure (pV, pV1, pV2) and has a first monostable valve unit (6) for providing a first parking brake pressure (pF1); a second compressed air path (4) receiving the reserve pressure (pV, pV1, pV2), having a second monostable valve unit (8) for providing a second parking brake pressure (pF2); and a first shuttle valve (10) having a first shuttle valve connection (10.1), which is connected to the first compressed air path (2) and receives a first parking brake pressure (pF1), a second shuttle valve connection (10.2), which is connected to the second compressed air path (4) and receives a second parking brake pressure (pF2), and a third shuttle valve connection (10.3), which can be connected to a spring accumulator brake cylinder (220a, 220b, 220c, 220d), the first shuttle valve (10) always regulates the higher one of the first parking brake pressure (pF1) and the second parking brake pressure (pF2) at the third shuttle valve connection (10.3). The invention also relates to a brake system (202) and to a commercial vehicle (210).
本发明涉及一种用于商用车辆(202)的能电子控制的气动制动系统(210)的驻车制动阀组件(1),驻车制动阀组件包括:接收储备压力(pV、pV1、pV2)的第一压缩空气路径(2),其具有用于提供第一驻车制动压力(pF1)的第一单稳态阀单元(6);接收储备压力(pV、pV1、pV2)的第二压缩空气路径(4),其具有用于提供第二驻车制动压力(pF2)的第二单稳态阀单元(8);以及第一梭阀(10),其具有与第一压缩空气路径(2)并接收第一驻车制动压力(pF1)的第一梭阀接口(10.1)、与第二压缩空气路径(4)并接收第二驻车制动压力(pF2)的第二梭阀接口(10.2)以及能与弹簧蓄能制动缸(220a、220b、220c、220d)连接的第三梭阀接口(10.3),其中,第一梭阀(10)总是在第三梭阀接口(10.3)上调控出第一驻车制动压力(pF1)和第二驻车制动压力(pF2)中的较高者。本发明还涉及一种制动系统(202)以及一种商用车辆(210)。
