Hydraulic control circuit for a dual clutch transmission of a motor vehicle has actuators that are respectively coupled to valve assemblies to initiate pairs of gear ratios

摘要

Two solenoids (150,152) respectively receive two pressurized fluid flows. Three valve assemblies (170,172,174) communicate with each other via the first valve assembly. The first valve assembly is coupled to the two solenoids. Two actuators (180,182,184,186) are coupled to the second valve assembly for respectively initiating two pairs of gear ratios. Third and fourth actuators are coupled to the third valve assembly to respectively initiate third and fourth pairs of gear ratios.
