Beschreibung
Zusammenfassung:	The invention relates to a hydraulic parking oil supply system of an automatic transmission. The hydraulic parking oil supply system comprises a proportional pressure regulating electromagnetic valve, a one-way valve, a clutch direct-drive electromagnetic valve, a pressure sensor, a clutch, a synchronizer flow control electromagnetic valve, a parking electromagnetic valve, a first synchronizer, a second synchronizer, a parking mechanism, a parking locking electromagnet and a back pressure valve. An inlet of the proportional pressure regulating electromagnetic valve is connected with main oil pressure, and an outlet is connected with the clutch direct-drive electromagnetic valve, the synchronizer flow control valve and the parking electromagnetic valve; and a pressure relief opening of the proportional pressure regulating electromagnetic valve, a pressure relief opening of the clutch direct-drive electromagnetic valve, an oil drainage opening of the synchronizer flow control electromagnetic valve and an oil dr
