The invention belongs to the technical field of vehicles, and particularly relates to a double-fluid hydraulic drive-by-wire brake system. A hydraulic power unit of the double-fluid hydraulic drive-by-wire brake system is connected with a hydraulic-hydraulic pressurizing unit through a hydraulic oil pipeline. And the output ends of the hydraulic-hydraulic pressurizing unit, the brake fluid storage tank and the brake fluid energy accumulator are connected with the input end of the brake control valve group through a brake fluid pipeline. And the brake control valve group is connected with the brake through a brake fluid pipeline. And the braking system adopts a double-liquid-source system design. Wherein the hydraulic oil power subsystem is a power system, and the brake fluid subsystem is an execution system. The design functions of the system are separated and do not interfere with each other. And a liquid-liquid pressurizing structural design is adopted, so that the braking force can be increased. When the hydraulic oil part of the system breaks down, the brake fluid part can still work, and the overall reliability of the system is high. A pipeline of hydraulic oil and brake fluid from an oil tank or a brake fluid storage tank to an execution part is short, and the system response speed is high. And the system has expansibility, and a power subsystem can be expanded into an electric-hydraulic power subsystem.
本发明属于车辆技术领域,具体涉及一种双流体液压线控制动系统,其液压动力单元与液‑液增压单元通过液压油管路连接。液‑液增压单元、制动液储液罐、制动液蓄能器输出端通过制动液管路与制动控制阀组输入端连接。制动控制阀组通过制动液管路与制动器连接。所述制动系统采用双液源系统设计。其中,液压油动力分系统为动力系统,制动液分系统为执行系统。该系统设计功能分离、互不干扰。采用液‑液增压结构设计,可增大制动力。该系统液压油部分故障时,制动液部分仍可工作,系统整体可靠度高。液压油和制动液从油箱或制动液储液罐至执行部件管路较短,系统响应速度快。且系统有拓展性,动力分系统可拓展为电‑液动力分系统。
