A drive train cooling arrangement for motor vehicles has a first cooling circuit and a second cooling circuit and has a pump arrangement, by means of which coolant can be fed to the first and the second cooling circuit. The pump arrangement has a bidirectional pump, which has a first pump port and a second pump port and which can be driven by a pump electric motor. The first pump port is connected to the first cooling circuit, wherein the second pump port is connected to the second cooling circuit. A coolant volume flow which is provided for at least one of the first and the second cooling circuit can be adjusted by changing the rotational speed of the pump electric motor.

Drive train cooling arrangement and method for operating same

A drivetrain for a motor vehicle has a first electric machine provides drive power, wherein the first electric machine is connected to an electrical energy store. A differential can distribute drive power to two driven wheels or axles of the motor vehicle. A first transmission arrangement which connects the first electric machine to the differential. A second electric machine which is coupled to an internal combustion engine in order to charge the electrical energy store in a generator mode. A second transmission arrangement connects the internal combustion engine to the differential. The second transmission arrangement has a first gear stage and a second gear stage which can be alternately engaged, for the transmission of drive power from the internal combustion engine to the differential, by means of a clutch arrangement.

Drivetrain for a motor vehicle

A clutch arrangement for a drivetrain of a motor vehicle. The clutch arrangement has a first clutch, a second clutch, and a hydraulic actuator arrangement. The actuator arrangement has a first hydraulic cylinder for actuating the first clutch and a second hydraulic cylinder for actuating the second clutch. The actuator arrangement has an actuator pump which is driven by means of an electric motor and which can be operated in two directions of rotation. The actuator pump has a first port, which is connected to the first hydraulic cylinder, and a second port, which is connected to the second hydraulic cylinder. The actuator arrangement actuates the first or the second clutch depending on the direction of rotation of the actuator pump.

Clutch arrangement and drivetrain for a motor vehicle

A transmission configuration includes an automated dual-clutch transmission having two transmission sections with respective input shafts, respective output shafts and respective motor clutches. The motor clutches are connected, on a motor side thereof, to a drive shaft and to a respective one of the input shafts on a transmission side thereof. A drive-side speed sensor unit is disposed at the drive shaft. An input-side speed sensor configuration includes sensor wheels connected, fixed against relative rotation, to respective ones of the input shafts, and pulse sensors disposed stationary with respect to a housing and within an effective range of the respective sensor wheels. The input-side speed sensor configuration is configured to detect a speed of the input shafts and a direction of rotation of at least one of the input shafts. A method for controlling an automated dual-clutch transmission is also provided.
