The invention discloses a dual-motor power-assisted integrated brake system, which comprises an oil can, a pedal brake mechanism and two electric drive brake mechanisms, and is characterized in that the pedal brake mechanism comprises a main cylinder, a brake pedal, a pedal position sensor and a pedal feedback assembly; inlets of the two electrically-driven brake mechanisms are both communicated with an outlet of the oil can, outlets of the two electrically-driven brake mechanisms are communicated with the two brakes respectively, and the electrically-driven brake mechanisms are used for inputting brake fluid with set pressure into oil inlets of the corresponding brakes respectively according to the stroke, detected by the pedal position sensor, of the piston rod. The double-motor direct-push type hydraulic brake has the beneficial effects that a double-motor direct-push type structure is adopted, a set of motor plunger pump is additionally arranged on the basis of existing single-motor direct-push in the industry, higher braking force and more brake fluid displacement can be provided, and medium-sized vehicles of 5-10 tons can be covered; the front and rear brake circuits are powered by two motors respectively, so that the redundancy capability of the system is stronger.
本发明公开了一种双电机助力的集成式制动系统,包括油壶、踏板制动机构及两个电驱制动机构,所述踏板制动机构包括主缸、制动踏板、踏板位置传感器及踏板反馈组件;两个所述电驱制动机构的进口均与所述油壶的出口连通,两个所述电驱制动机构的出口分别与两组制动器连通,并用于根据所述踏板位置传感器检测到活塞杆的行程,分别输入设定压力的制动液于对应的一组制动器的进油口。本发明的有益效果是:采用了双电机直推式的结构,在行业现有单电机直推的基础上增加了一套电机柱塞泵,可提供更高的制动力、更多的制动液排量,可覆盖5‑10吨的中型车辆;前后制动回路分别由两个电机提供动力来源,系统冗余能力更强。
