A braking system for vehicles (4) comprising a pilot pump (8, 108, 110) equipped with manual actuation means (9), lever- and/or pedal- operated, which is fluidically connected to a hydraulic actuatordevice (12, 112, 114) which is operatively connected to a braking device (16, 116, 118) associated with a wheel (5, 6) of said vehicle, wherein the hydraulic actuator device delimits a first and a second actuation chamber (20, 24) separated fluidically by a septum (28) movable in an axial direction (X-X), wherein the first actuation chamber (20) delimits a first volume (32) which contains fluid pressurized by the pilot pump via the manual actuation means, wherein the second actuation chamber (24) delimits a second volume (36) which contains pressurised fluid and is equipped with a delivery duct (40) fluidically connected to said braking device. The hydraulic actuator device comprises a by-pass (44), configured to fluidically connect or disconnect the first actuation chamber and the delivery duct. The movable septum is connected to motor means (48, 148, 150) so that it may translate axially, regardless of the braking action imposed by the pilot pump via the manual actuation means. The system (4) is comprising a control unit (56) operatively connected with said motor means and programmed to switch from a standard operating condition or deactivation of the motor means, wherein the movable septum places in communication the first actuation chamber with the by-pass, with the second actuation chamber and with the delivery duct, to a braking correction condition wherein the motor means are actuated to translate the movable septum so that the first actuation chamber is separated fluidically from the delivery duct, and so that the second actuation chamber is fluidically connected tothe delivery duct to control the actuation of the braking device via the pressurised fluid contained in the second actuation chamber, wherein the movable septum comprises a collar (53) and a stem (54), the collar realising the hydraulic separation between the first and second actuation chamber, the stem passing through said first and second actuation chamber and being operatively connected to themotor means.

    用于交通工具的制动系统(4),包括:杠杆和/或踏板操作的、配备有手动致动装置(9)的先导泵(8、108、110),该先导泵与液压致动器装置(12、112、114)流体地连接,该液压致动器装置被可操作地连接到与所述交通工具的轮(5、6)相关联的制动装置(16、116、118),其中,液压致动器装置界定由沿轴向方向(X‑X)可移动的隔板(28)流体地分离的第一和第二致动室(20、24),其中,第一致动室(20)界定容纳由先导泵经由手动致动装置加压的流体的第一容积(32),其中,第二致动室(24)界定容纳经加压的流体的第二容积(36),并且配备有与所述制动装置流体地连接的输送管道(40)。液压致动器装置包括被配置成使第一致动室和输送管道流体地连接或断开连接的旁路(44)。可移动隔板被连接到电机装置(48、148、150),使得其可以轴向地平移,而与由先导泵经由手动致动装置施加的制动作用无关。系统(4)包括控制单元(56),该控制单元与所述电机装置可操作地连接并且被编程为使电机装置从标准运行状态或停用切换至制动校正状态,在标准运行状态或停用中,可移动隔板放置成使第一致动室与旁路连通、与第二致动室连通并且与输送管道连通,在制动校正状态中,电机装置被致动以使可移动隔板平移,使得第一致动室与输送管道流体地分离,并且使得第二致动室被流体地连接到输送管道,以经由第二致动室中容纳的经加压的流体来控制制动装置的致动,其中,可移动隔板包括杆环(53)和柱杆(54),杆环实现第一和第二致动室之间的液压分离,柱杆穿过所述第一和第二致动室并且被可操作地连接到电机装置。
