The invention discloses a redundant braking system, and belongs to the technical field of redundant braking. The redundant braking system comprises a redundant braking unit which comprises a redundant pressure building module for building redundant pressure; and the redundant braking unit further comprises a first control valve, and the first control valve is used for controlling connection or disconnection between the output port of the redundant pressure buildup module and the wheel cylinder. The system has the beneficial effects that: the first control valve is arranged and controls connection or disconnection between the output port of the redundant pressure building module and the wheel cylinder, on one hand, when the wheel cylinder leaks, the first control valve correspondingly connected to the wheel cylinder can be closed, and therefore the situation that the leaked wheel cylinder affects other normal wheel cylinders is prevented, so that the whole redundant braking system has a wheel cylinder leakage prevention function; and on the other hand, when the redundant pressure buildup module breaks down and fails, the first control valve is closed, so that connection between the redundant pressure buildup module and the wheel cylinder can be cut off, and the wheel cylinder can be well protected.

    本发明公开了一种冗余制动系统,属于冗余制动技术领域。冗余制动系统包括冗余制动单元,其包括用于建立冗余压力的冗余建压模块;所述冗余制动单元还包括第一控制阀,所述第一控制阀用于控制所述冗余建压模块的输出口与轮缸之间的连通或断开。有益效果:通过设置第一控制阀,并使第一控制阀控制冗余建压模块的输出口与轮缸之间的连通或断开,一方面能够在轮缸出现泄漏时,关闭与轮缸相对应连接的第一控制阀,从而防止泄漏轮缸对其它正常轮缸产生影响,以使整个冗余制动系统具有轮缸防泄漏功能;另一方面能够在冗余建压模块出现故障而失效时,通过关闭第一控制阀,以能够隔断冗余建压模块与轮缸之间的连接,以能够较好地保护轮缸。
