Title
(EN) VEHICLE PARKING BRAKE CONTROL SYSTEM, VEHICLE, AND TRAIN
(FR) SYSTÈME DE COMMANDE DE FREIN DE STATIONNEMENT DE VÉHICULE, VÉHICULE ET TRAIN

Abstract
(EN) A vehicle parking brake control system, a vehicle, and a train. The system comprises: a piston valve (1) and a parking brake cylinder (2). A brake pipe (3) of the vehicle is connected to a first gas port (11) of the piston valve (1); a second gas port (12) of the piston valve (1) is in communication with the atmosphere; the parking brake cylinder (2) is connected to a third gas port (13) of the piston valve (1). When the brake pipe (3) exhausts air, the second gas port (12) of the piston valve (1) is in communication with the third gas port (13) of the piston valve (1), so that the gas in the parking brake cylinder (2) sequentially passes through the third gas port (13) of the piston valve (1) and the second gas port (12) of the piston valve (1), and is discharged to the atmosphere. After exhausting, the parking brake cylinder (2) applies the pressure to wheels of the vehicle to generate the parking brake acting force on the vehicle. According to the parking brake control system, power does not need to be provided, which reduces the vehicle consumption cost. The manual operation on a button or a hand wheel, etc. does not need to be carried out, which saves manpower and avoids the misoperation of the staff.
(FR) Système de commande de frein de stationnement de véhicule, véhicule et train. Le système comprend : une soupape à piston (1) et un cylindre de frein de stationnement (2). Une conduite de frein (3) du véhicule est raccordée à un premier orifice de gaz (11) de la soupape à piston (1) ; un deuxième orifice de gaz (12) de la soupape à piston (1) est en communication avec l'atmosphère ; le cylindre de frein de stationnement (2) est raccordé à un troisième orifice de gaz (13) de la soupape à piston (1). Lorsque la conduite de frein (3) évacue de l'air, le deuxième orifice de gaz (12) de la soupape à piston (1) est en communication avec le troisième orifice de gaz (13) de la soupape à piston (1), de sorte que le gaz dans le cylindre de frein de stationnement (2) traverse séquentiellement le troisième orifice de gaz (13) de la soupape à piston (1) et le deuxième orifice de gaz (12) de la soupape à piston (1), et est évacué vers l'atmosphère. Après évacuation, le cylindre de frein de stationnement (2) applique la pression à des roues du véhicule pour générer la force d'action de frein de stationnement sur le véhicule. Selon le système de commande de frein de stationnement, il n'est pas nécessaire de fournir une puissance, ce qui réduit le coût de consommation du véhicule. L'actionnement manuel d'un bouton ou d'un volant de direction, etc. n'a pas besoin d'être mis en œuvre, ce qui permet de réaliser des économies de main d'œuvre et d'éviter une fausse manœuvre du personnel.
(ZH) 一种车辆停放制动的控制系统、车辆和列车。该系统包括:活塞阀(1)和停放制动缸(2),其中,车辆的制动管(3)与活塞阀(1)的第一气口(11)连接,活塞阀(1)的第二气口(12)与大气连通;停放制动缸(2)与活塞阀(1)的第三气口(13)连接。在制动管(3)排风时,活塞阀(1)的第二气口(12)与活塞阀(1)的第三气口(13)连通,以使停放制动缸(2)中的气体依次通过活塞阀(1)的第三气口(13)、活塞阀(1)的第二气口(12)排向大气。停放制动缸(2)在排气后,对车辆的车轮施加压力,以对车辆产生停放制动作用力。该停放制动控制系统,不需要提供电力降低车辆消耗成本,也不需要人为的进行按钮或手轮等的操作,节省了人力,避免了人员的操作失误。
