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.

Claim (Index 1):
A hydrostatic transmission for a traction drive, comprising:\n a primary unit coupled to an internal combustion engine of the traction drive; at least one secondary unit coupled to an output of the traction drive; two working lines of a closed circuit configured to fluidically connect the primary unit and the at least one secondary unit; an electrical control unit, wherein each of the primary unit and the at least one secondary unit have an adjustable pivot angle or an adjustable swept volume which are controllable by the electrical control unit during a braking operation of the hydrostatic transmission; and a P closed-loop controller configured for closed-loop control of a required total braking torque or of a value proportional to the required total braking torque, wherein an input variable of the P closed-loop controller is (i) a traveling speed difference between a setpoint traveling speed and an actual traveling speed, or (ii) a difference proportional to the former between a setpoint rotational speed and an actual rotational speed of the at least one secondary unit.
