The invention discloses a dual-motor direct-drive auxiliary master cylinder brake-by-wire system with a redundancy function, relates to the field of automobile braking, and adopts a dual-motor direct-drive auxiliary master cylinder form to realize reliable pressure buildup of the system under the condition of guaranteeing the rapid pressure buildup capability of the system. By using the parallel shaft one-way clutch, the problem of forward and reverse rotation switching existing in braking of a traditional motor direct drive main cylinder is solved, the risk of motor faults is reduced, in addition, when a single motor of a main voltage buildup unit fails, power transmission can be quickly interrupted, and reliable voltage buildup of the other motor is guaranteed; the redundant voltage buildup unit is additionally arranged, reliable voltage buildup of the system under the double-motor failure condition of the main voltage buildup unit is achieved, the function and the structure of the system are analyzed, on the premise that the reliability of the system is guaranteed, a one-way valve with high safety is adopted to replace an electromagnetic valve, and the production cost of the system is reduced.
本申请公开了一种具有冗余功能的双电机直驱副主缸线控制动系统,涉及汽车制动领域,采用双电机直驱副主缸的形式,在保障系统快速建压能力的条件下,实现了系统可靠建压。通过使用平行轴单向离合器,解决了传统电机直驱主缸制动存在的正反转切换问题,降低了电机故障的风险,另外在主建压单元发生单电机失效时,可快速中断动力传递,保证另一电机可靠建压;增设冗余建压单元,实现了主建压单元双电机失效情况下的系统可靠建压,并通过分析系统的功能和结构,在保证系统可靠性的前提下采用安全性较高的单向阀代替电磁阀,降低了系统的生产成本。
