摘要: A pump assembly for a vehicle transmission that is coupled to a prime mover, a chain drive assembly, a hydraulic pump with a rotor, and a planetary gear set. A drive sprocket of the chain drive assembly is rotationally coupled with the prime mover. The planetary gear set includes first, second, and third members. The first member is rotatable with the pump and the third member is rotatable with the driven sprocket.

摘要: A method of controlling a hydraulic control system for a dual clutch transmission includes controlling a plurality of pressure and flow control devices in fluid communication with a plurality of clutch actuators and with a plurality of synchronizer actuators. The clutch actuators are operable to actuate a plurality of torque transmitting devices and the synchronizer actuators are operable to actuate a plurality of synchronizer assemblies. Selective activation of combinations of the pressure control solenoids and the flow control solenoids allows for a pressurized fluid to activate at least one of the clutch actuators and synchronizer actuators in order to shift the transmission into a desired gear ratio.

摘要: A hydraulic control system for a dual clutch transmission includes a plurality of pressure and flow control devices and logic valve assemblies in fluid communication with a plurality of clutch actuators and with a plurality of synchronizer actuators.
