1. A hydrostatic traction drive for a laterally-steered vehicle, comprising:
a left secondary unit;
a right secondary unit, the left and right secondary units configured as hydrostatic adjustable and through-pivotable axial piston machines; and
a common hydrostatic adjustable primary unit configured to supply the left and right secondary units via an open hydrostatic circuit,
wherein the primary unit is pressure-controlled, while the left and right secondary units are torque-controlled, and
wherein the traction drive has a steering function for the vehicle, which is implemented via unequal or separate control of the torque of the left and right secondary units.
