Abstract

A drive train of a vehicle has a drive motor and a traction drive driven by the drive motor. A hydraulic work system has at least one hydraulic pump driven by the drive motor. To deliver torque into the drive train and/or to absorb torque from the drive train, the drive train is provided with an additional hydraulic machine which can be placed in communication with a hydraulic pressure accumulator and/or a tank and can be operated as a pump and a motor in the same direction of rotation. The hydraulic machine has an inlet connection and an outlet connection and a switching valve device is provided to control the connection of the inlet connection and the outlet connection with the pressure accumulator or the tank.
