The invention relates to a parking brake valve assembly (1) for a pneumatic brake system of a utility vehicle, comprising at least one first parking brake valve unit (2) and at least one second parking brake valve unit (4), the first parking brake valve unit (2) being actuated by a first parking brake signal (SF1) and the second parking brake valve unit (4) being actuated by a second parking brake signal (SF2). The first parking brake valve unit (4) is actuated by means of a first parking brake signal (SF2) and can be switched from a first switching position (2A) into a second switching position (2B), and the second parking brake valve unit (4) is actuated by means of a second parking brake signal (SF2) and can be switched from the first switching position (4A) into the second switching position (4B). The first parking brake signal (SF1) and the second parking brake signal (SF2) are independent of each other. The first parking brake valve unit (2) and the second parking brake valve unit (4) are pneumatically connected in series between a parking brake reserve connection (6) and a parking brake working connection (8), the parking brake valve unit (2, 4) has a switching position (2A, 2B, 4A, 4B) such that the parking brake working interface (8) can be supplied and deflated by switching the other parking brake valve unit (2, 4) independently of the switching position (2A, 2B, 4A, 4B) of one parking brake valve unit (2, 4). The invention also relates to a parking brake module (100).

    本发明涉及用于商用车辆的气动制动系统的驻车制动阀组件(1),驻车制动阀组件具有至少一个第一驻车制动阀单元(2)和至少一个第二驻车制动阀单元(4),其中,第一驻车制动阀单元(2)通过第一驻车制动信号(SF1)驱控,并能从第一切换位置(2A)切换到第二切换位置(2B)中,并且第二驻车制动阀单元(4)通过第二驻车制动信号(SF2)驱控,并能从第一切换位置(4A)切换到第二切换位置(4B)中。第一驻车制动信号(SF1)和第二驻车制动信号(SF2)是彼此独立的。第一驻车制动阀单元(2)和第二驻车制动阀单元(4)以气动方式串联地接在驻车制动储备接口(6)与驻车制动工作接口(8)之间,使得不依赖于一个驻车制动阀单元(2、4)的切换位置(2A、2B、4A、4B)地能够相应地通过另一个驻车制动阀单元(2、4)的切换对驻车制动工作接口(8)进行送气和放气。本发明还涉及驻车制动模块(100)。
