Power split drive for mobile vehicle, particularly mobile machine for use as drive of vehicle, for example mobile utility vehicle such as tractor, has branching section and hydrostatic power branch formed with displacement body units

摘要

The power split drive (1) has a branching section (8), a power branch and a hydrostatic power branch. The hydrostatic power branch of a reversed, continuous hydrostatic derive (20) is formed with a displacement body unit (21) and another displacement body unit (22), where the displacement body units are operated in the closed cycle. The internal hydro-mechanical losses of the latter displacement body unit are increased with the increase of the supporting moment of the latter displacement body unit. An external brake torque is applied to the latter displacement body unit.
