The gear (1) has at least one hydropump (2), at least one first (4) and at least one second (5) hydromotor, which are adjusted by first (7) and second (9) adjusting devices respectively, and which are connected parallel to the hydropump in a hydraulic circuit (3,6). A control valve (14) is connected to a control pressure source (11) on its input side and to the adjustment devices on its output side. In a first valve position (17), both adjustment devices have the same control pressure. In a second valve position (22), the first adjustment device has such a control pressure that the first hydromotor is pushed back a minimum displacement volume, if the volume current through the first hydromotor is larger than that through the second hydromotor. In a third valve position (23), the second adjustment device has such a control pressure that the second hydromotor is pushed back a minimum displacement volume if the volume flow through the second hydromotor is larger than that through the first. |
