    • The present invention relates to a hydraulic system for a double piston, comprising a double piston that includes an acting piston, where a first acting surface and a second acting surface are formed, a first piston port which supplies hydraulic pressure to the first acting surface, and a second piston port which supplies hydraulic pressure to the second acting surface; a solenoid valve that receives clutch control pressure and communicates with the first piston port via a first flow path; a switch valve that receives the clutch control pressure from the solenoid valve, is connected to the second piston port through a second flow path, and selectively transmits the clutch control pressure to the second piston port; and a manual valve that receives line pressure and selectively transmits the line pressure to the switch valve so that the clutch control pressure is selectively transmitted to the second acting surface through the second flow path.
    • 本发明涉及一种双活塞液压系统,包括双活塞,其包括形成第一作用表面和第二作用表面的作用活塞,向第一作用表面提供液压的第一活塞端口, 以及向所述第二作用面供给液压的第二活塞端口; 电磁阀,其接收离合器控制压力并经由第一流路与第一活塞端口连通; 接收来自电磁阀的离合器控制压力的切换阀通过第二流路连接到第二活塞端口,并且选择性地将离合器控制压力传递到第二活塞端口; 以及手动阀,其接收管路压力并选择性地将管路压力传递到开关阀,使得离合器控制压力通过第二流动路径选择性地传递到第二作用表面。
