Abstract

The hydrostatic gearbox has a pump adjustable in delivery volume by an adjusting device (6) and a hydro motor (4) in closed circuit. The hydro motor is adjustable by another adjusting device (5) in sip volume. A speed synchronization between the speed of the hydro motor and a output shaft (9) of the manual gearbox (S) is attainable by a control of the adjusting device of the hydromotor. A small temporary operation of the hydro static actuation is attainable by the control of the adjusting device of the pump. An independent claim is also included for a method for operating a hydrostatic gearbox.
