A transmission arrangement for a travel drive, in particular a mobile machine, includes a first hydraulic machine configured to be coupled to a drive machine, and a second hydraulic machine having an adjustable second expulsion volume, the second hydraulic machine configured to be connected fluidically to the first hydraulic machine via a first working line and a second working line of the transmission arrangement. The second hydraulic machine configured to be coupled or is coupled to a manual transmission of the transmission arrangement. The manual transmission has at least two transmission stages, and coupling of the second hydraulic machine to the manual transmission has the result that a torque can be transmitted. The transmission arrangement further includes a control apparatus configured to reduce to zero or to nearly zero the second expulsion volume at least during a changeover from one transmission stage to another transmission stage of the manual transmission.

A hydraulic machine, in particular for a transmission arrangement, has an adjustable displacement volume and an adjusting device configured to adjust the displacement volume. The adjusting device is connected to a control unit so that the adjusting device is configured to be actuated in accordance with a setpoint value of the displacement volume. A transmission arrangement includes the hydraulic machine. A method for controlling the transmission arrangement is disclosed.

A transmission arrangement for a travel drive includes a transmission input that is configured to be coupled to a working machine and a transmission output that is configured to be coupled to an output drive. The transmission arrangement further includes a hydrostatic transmission and a manual transmission coupled in series for the transmission of power between the transmission input and the transmission output. The manual transmission has changeable transmission stages at least when the transmission output is at a standstill. A control device is configured to change the transmission stages.
