The invention discloses an electro-hydraulic integrated high-speed switch valve for a vehicle, and belongs to the technical field of vehicles. A valve seat is tightly arranged in a first central holeof a valve body, an oil inlet is formed in the outer end of the first central hole, a control oil port is formed in the valve body, a control oil port filter screen is arranged on the outer wall of the control oil port, an oil inlet filter screen is arranged in the oil inlet, and a first step hole of the valve body is in interference fit with a valve element guide ring. A wiring insulator on a wiring terminal is embedded into a second central hole of the valve body, a coil framework is arranged on the outer side of a pole shoe in a sleeving mode and arranged in a third central hole of the wiring insulator together with the pole shoe, a coil assembly is wound on the coil framework, a return spring and a plug are arranged in a fourth central hole of the pole shoe, one end of the return spring tightly presses the plug, and the other end of the return spring acts on a shoulder face of a conical valve element. The conical valve element serves as an armature in an electromagnetic subsystem and also serves as a valve element of a hydraulic subsystem, the mass of moving parts is small, the response speed of the valve is high, and integration of electromagnetic driving and oil control is achieved. The electro-hydraulic integrated high-speed switch valve is wide in application range.
一种车辆用电液一体式高速开关阀,属于车辆技术领域。阀座紧密设置在阀体的中心孔一内,中心孔一外端为进油口,阀体上设有控制油口,控制油口外壁上设有控制油口滤网,进油口内设有进油口滤网,阀体的台阶孔一与阀芯导向环过盈配合,接线端子上的接线绝缘体嵌入阀体的中心孔二中,线圈骨架套装在极靴外侧且一同设置在接线绝缘体的中心孔三内,线圈组件缠绕在线圈骨架上,极靴的中心孔四内设置有回复弹簧和堵头,回复弹簧一端压紧堵头,另一端作用在圆锥形阀芯上的台肩面上。圆锥形阀芯既作为电磁子系统中的衔铁,又作为液压子系统的阀芯,运动部件质量小、阀响应速度高,实现了电磁驱动和油液控制的一体化。本发明适用范围广。
