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 is introduced into the traction drive via the hydrostatic transmission, and is controlled in closed-loop fashion by an electronic control unit. A braking torque is controlled in closed-loop fashion indirectly by a swept volume of the secondary unit, for which purpose one or two closed-loop controllers are provided.
