Abstract
(EN)
A braking system (100) for use in a railway vehicle (200) and a railway vehicle (200), the braking system (100) comprising a hydraulic unit (3), a hydraulic braking control unit (2), electromechanical braking control units (5), and electromechanical units (6), an oil path (30m) of the hydraulic unit (3) being arranged to correspond to at least one brake (4), and the electromechanical braking control units (5) being arranged to correspond to at least one electromechanical unit (6). When the railway vehicle (200) implements service braking, the hydraulic braking control unit (2) is adapted to control the corresponding brake (4) to brake the vehicle wheels (11) by means of the oil path (30m); and when the railway vehicle (200) implements parking braking, at least one of the plurality of electromechanical braking control units (5) is adapted to brake the vehicle wheels (11) by means of the corresponding electromechanical unit (6).
(FR)
L'invention concerne un système de freinage (100) destiné à être utilisé dans un véhicule ferroviaire (200), ainsi qu'un véhicule ferroviaire (200) associé. Le système de freinage (100) selon l'invention comprend une unité hydraulique (3), une unité de commande de freinage hydraulique (2), des unités de commande de freinage électromécaniques (5) et des unités électromécaniques (6), un trajet d'huile (30m) de l'unité hydraulique (3) étant agencé de sorte à correspondre à au moins un frein (4), et les unités de commande de freinage électromécaniques (5) étant agencées de sorte à correspondre à au moins une unité électromécanique (6). Lorsque le véhicule ferroviaire (200) selon l'invention met en oeuvre un freinage de service, l'unité de commande de freinage hydraulique (2) est conçue pour commander le frein correspondant (4) afin de freiner les roues (11) du véhicule au moyen du trajet d'huile (30m) ; et lorsque le véhicule ferroviaire (200) met en oeuvre un freinage de stationnement, au moins une des unités de commande de freinage électromécaniques (5) de la pluralité est conçue pour freiner les roues (11) du véhicule au moyen de l'unité électromécanique correspondante (6).
(ZH)
一种用于轨道车辆(200)的制动系统(100)和轨道车辆(200),制动系统(100)包括液压单元(3)、液压制动控制单元(2)、机电制动控制单元(5)和机电单元(6),液压单元(3)的油路(30m)与至少一个制动器(4)对应设置,机电制动控制单元(5)与至少一个机电单元(6)对应设置。在轨道车辆(200)进行行车制动时,液压制动控制单元(2)适于通过油路(30m)控制对应制动器(4)对车轮(11)制动;在轨道车辆(200)进行停车后制动时,多个机电制动控制单元(5)中的至少一个适于通过对应机电单元(6)对车轮(11)制动。
