Abstract: A hydrostatic transmission for a traction drive includes a variable-displacement pump and one or more motors coupled to one another in a closed hydraulic circuit. A braking operation by means of the transmission can be initiated in the traction drive by an electronic control unit if there is a risk of overspeeding of an associated internal combustion engine. The braking operation is initiated if at least two activation thresholds are overshot, of which a first activation threshold is variable whereas the further activation threshold is fixed or variable.

Abstract: A hydrostatic transmission is configured to realize a braking operation in which at least one adjustable traction motor, which acts as a pump, is supported via a closed circuit on an adjustable axial piston pump, which acts as a motor, and which in turn is supported on an internal combustion engine. Since overspeeding of the latter should be avoided, a control unit adjusts the pivot angle of the pump in accordance with a characteristic map which represents a relationship between a setting force and a pressure difference of two working lines of a closed circuit, a pump rotational speed, and the pivot angle. Thus, characteristic-map-based pilot control of the pivot angle of the pump is possible and feedback of the present pivot angle is omitted.
