Integrated Pump / Motor Drive Units

Stepless for optimum performance

Precise transmission control for simple operation without interrupting tractive effort. From stand still to maximum speed. Stepless. Together with the customer Linde Hydraulics defines new standards in technology. Advanced modular drive technology, realised in hydrostatic variators for variable speed transmission, form the core of power split gearboxes. Compact units with a hollow shaft are available for mounting to conventional gearboxes in smaller machines. These compact units are used as fully hydrostatic systems with PTO drive. With customer-specific developments, Linde Hydraulics supports the change from power shift to continuous variable transmission technology.
