A brake system (4) for a motor vehicle (8), comprising at least a first brake device (12) operatively connected to a first wheel (16) of the motor vehicle (8) and provided with a first hydraulic supply circuit (20), a first electric actuator (24) having an electrically or electromechanically actuated first motor device operatively connected to a first electrically or electromechanically actuated piston (28), the first piston is fluidly connected to a first hydraulic supply circuit (20), at least one first interface or inlet (32), operatively connected to a first hydraulic device (36) provided with a first manually operated piston (40), where the first manually operated piston (40) is divided into a first direct piston (41) directly connected to the first interface (32) and a first indirect piston (42) directly connected to the second interface (32). A first indirect piston (42) is arranged contiguously with the first direct piston (41) and is connected thereto by inserting a first return spring (43), the first indirect piston (42) is hydraulically connected to the first hydraulic supply circuit (20) via a first bypass conduit (44) and is arranged upstream contiguously with a first electrically or electromechanically actuated piston (28). The brake system (4) comprises a hydraulic fluid reservoir (52) fluidly connected to the first hydraulic device (36) by a communication conduit (56) upstream of the first indirect piston (42) and a communication conduit (60) downstream of the first indirect piston (42), where the brake system (8) is provided with a processing and control unit (68), and a first electrically or electromechanically actuated piston (28) operatively connected to said first electric actuator (24) and programmed such that, in standard operation, upon actuation of the first interface (32), the first electrically or electromechanically actuated piston (28) translates to: block the first bypass conduit (44), fluidly disconnect the first manually operated piston (40) from the first hydraulic supply circuit (20), and simultaneously actuate the at least one first brake device (12).
一种用于机动车(8)的制动系统(4),包括至少第一制动装置(12),操作性地连接至机动车(8)的第一轮(16),并且设置有第一液压供给回路(20),第一电致动器(24),具有电致动或机电致动的第一马达装置,第一马达装置操作性地连接至第一电致动或机电致动活塞(28),第一活塞流体地连接至第一液压供给回路(20),至少一个第一接口或输入口(32),操作性地连接至设置有第一手动操作活塞(40)的第一液压装置(36),其中,第一手动操作活塞(40)被分为第一直接活塞(41)和第一间接活塞(42),第一直接活塞直接连接至第一接口(32),第一间接活塞与第一直接活塞(41)连续设置且通过将第一复位弹簧(43)置入的方式连接至第一直接活塞,第一间接活塞(42)通过第一旁通管道(44)液压地连接至第一液压供给回路(20),并且与第一电致动或机电致动活塞(28)连续地布置在第一活塞上游。制动系统(4)包括液压流体储蓄器(52),通过在第一间接活塞(42)上游的连通管道(56)和在第一间接活塞(42)下游的连通管道(60)流体地连接至第一液压装置(36),其中,制动系统(8)设置有处理和控制单元(68),操作性地连接至所述第一电致动器(24)并且被编程为使得:在标准操作中,在致动第一接口(32)时,第一电致动或机电致动活塞(28)平移,从而:阻塞第一旁通管道(44),使第一手动操作活塞(40)从第一液压供给回路(20)流体断开,并且同时致动至少一个第一制动装置(12)。
