Abstract: The invention relates to a power split gearbox for a motor vehicle. The power split gearbox comprises a drive shaft which can be connected to an internal combustion engine in order to feed in torque, a first mechanical branch with a planetary gear mechanism arrangement, an infinitely variable second branch which can be connected to the first branch and comprises two adjustable energy converters which can be coupled to one another in energy terms and can be operated in each case in both directions, and at least one output shaft which can be coupled to the drive shaft via the first and the second branch.

Abstract: Disclosed is a power-branched transmission, particularly for agricultural vehicles such as tractors or similar, having a stepped planetary gear which is disposed between an input shaft and an output shaft and is used for dividing the power supplied at the input shaft onto a mechanical power branch and a hydraulic power branch. The hydraulic power branch is formed by two hydraulically interconnected, identical hydrostatic axial piston engines which can be selectively operated as a pump or an engine, can be swiveled within a predefined pivoting angle, and can be connected to the input shaft or the stepped planetary gear in a different manner via two respective clutches so as to cover different operating ranges or running steps. In order to obtain better efficiency in such a power-branched transmission, the two hydrostatic axial piston engines are configured as wide-angle hydrostats that are provided with a minimum pivoting angle range of 45°.

Abstract: The invention relates to a hydrostatic axial piston machine having a cylinder block which can be rotated about a first axis, the cylinder block being provided with a plurality of cylinder bores which extend in the axial direction and which are arranged on a partial circle which is concentric in relation to the first axis, in addition to a plane which can be rotated about a second axis, whereon a number of pistons associated with the bores, can be articulated in a pivotable manner on a second partial circle which is concentric in relation to the second axis and form a ring. Also provided is a device for synchronizing the rotation of the cylinder block about the first axis and the drive shaft about the second axis. The cylinder block and the drive shaft can be adjusted in a continuous manner using both axes, between a first position, wherein both axes are parallel, and a second position, wherein both axes together form a maximum pivoting angle which is different from zero.
