Abstract
A hydrostatic traction drive includes a hydrostatic pump and a hydrostatic motor connected to each other in an open circuit. One of the pump and motor is pressure-regulated while the other is torque-controlled or regulated in terms of pivot angle. A braking mode is therefore possible in which the secondary-side braking torque can be adapted to the permissible primary-side supporting torque of a primary machine coupled to the pump. To further increase the braking power, even in a high rotational phase of the primary machine, the permissible drag torque thereof can be temporarily exceeded. To further increase the braking power and therefore to have high-performance braking during operation, further means for converting energy can be provided in order to adjust a secondary-side braking torque and a primary-side supporting torque independently of each other.
