The invention relates to a hydraulic automatic transmission fault running system and a hydraulic automatic transmission. The problems that an electric control system does not work due to faults of electric control elements such as an electric control unit, a connecting wire harness, a sensor and an electromagnetic valve of the hydraulic automatic transmission, consequently the transmission is outof control, and a vehicle stops running suddenly are solved. The hydraulic automatic transmission fault running system comprises an electromagnetic valve assembly, a reversing valve assembly, a switching valve and a pilot valve. When the transmission works normally at a certain gear position, one or two of a first electromagnetic valve and a second electromagnetic valve in the electromagnetic valve assembly of the hydraulic automatic transmission fault running system is/or electrified to work at the moment, one or two of a clutch C1 and a cluch C2 is/are combined, and the vehicle can run underthe certain designated gear position; and when the transmission enters a fault running mode, in other words, after the fault running mode is executed, the clutch C1 and a clutch C3 or the clutch C2 and clutch C3 or the clutch C1 and the clutch C2 are combined, it is ensured that the vehicle can run to the proper parking spot for fault maintenance with the proper gear position, the traffic is notaffected, and safety accidents are avoided.

    本发明涉及一种液压自动变速器故障行驶系统及液压自动变速器,克服因液力自动变速器的电控单元、连接线束,传感器,电磁阀等电控元件故障引起的电控系统罢工,导致变速器不受控制,车辆突然停止运行的问题。包括电磁阀组件、换向阀组件、开关阀及先导阀;当变速器在某一档位正常工作时,本发明系统电磁阀组件中的第一电磁阀和第二电磁阀必有一个或两个此时通电工作,此时离合器C1和离合器C2有一个或两个结合,实现汽车在某指定档位下行驶;当变速器进入故障行驶模式即故障行驶模式后,自动使离合器C1和C3、C2和C3或C1和C2结合,保证车辆能够以合适的档位运行到合适的停车点进行故障检修,不影响交通,避免发生安全事故。
