HYDROSTATIC TRANSMISSION, DRIVE TRAIN HAVING THE TRANSMISSION AND METHOD FOR CONTROLLING THE TRANSMISSION

摘要

A hydrostatic transmission for a drive train is disclosed, said transmission comprising a first hydraulic machine that can be coupled to a drive machine and comprises an adjustable first displacement volume and is arranged together with at least one second hydraulic machine of the transmission in a hydraulic circuit and said second hydraulic machine can be coupled to an output of the drive train, wherein a control pressure of the transmission at the first hydraulic machine is effective in the direction in which the first displacement volume is increased and a working pressure of the second hydraulic machine that is dependent upon this adjustment is effective in the opposite direction, so that the working pressure can be controlled by way of the control device of the transmission by means of changing the control pressure. A hydrostatic drive train having this transmission is disclosed and a method for controlling the transmission of said drive train is disclosed.
