The invention relates to a parking brake valve (12) for a trailer (202), comprising a supply port (10) for connection to a pneumatic pressure supply line (206) of a towing vehicle (300), a delivery port (18) for connection to a parking brake actuator (228), preferably via a brake module (226), an exhaust port (24) and an internal line (30, 31). Furthermore, the parking brake valve (12) comprises a main valve (26) comprising a first position (48) connecting the internal line (30, 31) to the delivery port (18) for providing pneumatic pressure at the internal line (30, 31) to the delivery port (18) and a second position (32) connecting the exhaust port (24) to the delivery port (18) for discharging pneumatic pressure at the delivery port (18) to the exhaust port (24). Furthermore, the parking brake valve (12) comprises internal valves (28, 29), the internal valve includes a first position (50) connecting the supply port (10) to the internal line (30, 31) to provide pneumatic pressure at the pneumatic pressure supply line (206) to the internal line (30, 31), a second position (36) blocking a connection between the internal line (30, 31) and the supply port (10), and a pilot port (16) for connecting to a pneumatic pressure control line (210) of a trailer (202) connected to a tractor vehicle (300), the internal valve (28, 29) is arranged to switch from the second position (36) to the first position (50) when a pneumatic pressure above a switching pressure threshold (78) is provided on the pilot port (16). The invention also relates to a braking system for a trailer, a vehicle (200), a vehicle combination (100) and a method (68) for controlling a parking brake (230).
本发明涉及一种用于拖车(202)的驻车制动阀(12),其包括用于连接到牵引车(300)的气动压力供应管线(206)的供应端口(10)、用于优选地经由制动模块(226)连接到驻车制动器执行机构(228)的输送端口(18)、排气端口(24)和内部管线(30、31)。此外,驻车制动阀(12)包括主阀(26),主阀(26)包括第一位置(48)和第二位置(32),第一位置(48)将内部管线(30、31)连接到输送端口(18),用于将内部管线(30、31)处的气动压力提供到输送端口(18),第二位置(32)用于将排气端口(24)连接到输送端口(18),用于将输送端口(18)处的气动压力排放到排气端口(24)。此外,驻车制动阀(12)包括内部阀(28、29),内部阀包括将供应端口(10)连接到内部管线(30、31)以将气动压力供应管线(206)处的气动压力提供到内部管线(30、31)的第一位置(50)、阻挡内部管线(30、31)和供应端口(10)之间的连接的第二位置(36)以及用于连接到与牵引车(300)相连接的拖车(202)的气动压力控制管线(210)的先导端口(16),其中,内部阀(28、29)被布置成:当在先导端口(16)上提供高于切换压力阈值(78)的气动压力时,从第二位置(36)切换到第一位置(50)。本发明还涉及用于拖车的制动系统、车辆(200)、车辆组合(100)和用于控制驻车制动器(230)的方法(68)。
