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.
