DRIVE TRAIN FOR A MOTOR VEHICLE

摘要

The invention relates to a drive train for a motor vehicle, comprising a clutch device (202) disposed between a drive unit and a gearbox (232) for transmitting torque between the drive unit and the gearbox. The clutch consists of at least one clutch arrangement (204, 206) which can be actuated by transmission of a pressure medium and which is provided for operation under the effect of an operating medium. The gearbox can be actuated by means of an associated actuator system (234) when a pressure medium is transmitted. A pump arrangement (209), which can be commonly actuated or actuated by the drive unit, makes it possible for i) the pressure medium to be provided for actuation of the clutch, enables ii) the pressure medium to be fed to the clutch for operation under the effect of said pressure medium and enables iii) the pressure medium to be provided for the actuation of the gearbox. The pump arrangement comprises at least one pump (209) which can be controlled or adjusted with respect to the discharge pressure or/and with respect to the discharge volume flow.
