Abstract
The invention concerns a method and a transmission arrangement for changing gears in a transmission with a hydrostatic transmission and a manual gearbox () connected downstream from it. First the output torque of a hydrostatic motor () is reduced. After the reduction of the output torque of the hydrostatic motor (), an engaged gear () of the manual gearbox () which is connected downstream is disengaged. An output rotational speed of the hydrostatic motor () corresponding to the gear () to be engaged is determined. The gear ratio of the hydrostatic transmission is then adjusted, so that the output rotational speed of the hydrostatic motor () is higher than the determined corresponding output rotational speed. After this increased output rotational speed is reached, the gear () to be engaged is engaged.
