The invention relates to a two-stage pilot-operated type pedal simulator isolating valve for an integrated intelligent braking system, and belongs to two-stage pilot-operated type normally-closed electromagnetic valves of braking systems. Comprising a valve seat, a valve element, a valve element sheath, a filter screen, a valve body, a coil lower yoke, an armature, a spring, a coil winding, a coil framework, a plunger tube, static iron, a coil PIN, coil damping rubber, a coil shell yoke and a positioning column. The valve sleeve structure has the advantages that the structure is novel, the valve sleeve structure is integrated on the valve seat, the valve sleeve structure and the valve seat are integrated, a failure link and an assembly procedure are omitted, the assembly procedure is simplified, the assembly rhythm of a production line is accelerated, the installation space is reasonable, and the whole structure space is reduced; the PEEK valve element is small in conduction coefficient when collided with the valve seat and collided by the armature, excellent in NVH performance, non-magnetic, small in inertia and suitable for high-frequency PWM control.

    本发明涉及一种用于集成智能制动系统的两级先导式踏板模拟器隔离阀,属于制动系统的两级先导式常闭电磁阀。包括阀座、阀芯、阀芯护套、滤网、阀体、线圈下轭、衔铁、弹簧、线圈绕组、线圈骨架、隔磁管、静铁、线圈PIN、线圈减振橡胶、线圈外壳轭铁和定位柱。优点是结构新颖,阀套结构集成到阀座上,合二为一成为一体化设计,少了一个失效环节和一个装配工序,简化装配工序,加快产线装配节拍,安装空间合理,缩小整个结构空间;PEEK阀芯与阀座撞击和被衔铁撞击传导系数小,NVH性能优良,同时不导磁,惯量小,适合高频PWM控制。
