摘要： 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°.

摘要： 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.
摘要翻译：本发明涉及一种具有可围绕第一轴线旋转的气缸体的静液压轴向活塞机，所述气缸体设置有沿轴向延伸的多个气缸孔，其布置在同心的部分圆周上相对于第一轴线，除了可以围绕第二轴线旋转的平面之外，其中与孔相关联的多个活塞可以以可枢转的方式铰接在第二部分圆周上，第二部分圆相对于第二轴是同心的第二轴并形成环。还提供了一种用于使围绕第一轴线的气缸体的旋转和围绕第二轴线的驱动轴同步的装置。可以使用两个轴在两个轴平行的第一位置和第二位置之间以连续的方式调节气缸体和驱动轴，其中两个轴一起形成不同于零的最大枢转角度。
