Abstract:
A power-split transmission for a traction drive includes a hydraulic power branch and a further power branch. In order to control a velocity, a displacement volume of a hydraulic pump of the hydraulic power branch is configured to be adjusted by a hydraulic actuating device. For the purpose of adjustment, a control pressure medium can be applied to the actuating device by a control valve. An additional pressure-control device is configured to be used to set a control pressure of the control pressure medium to a setpoint value which is dependent on a drive range of the transmission or of the traction drive.
