Hydrostatic Axial Piston Machine Utilizing A Bent-Axis Construction

摘要

A hydrostatic axial piston machine (1) with a bent-axis construction has a drive shaft (4) with a drive flange (3) rotatable around an axis of rotation (Rt). A cylinder drum (7) has an axis of rotation (Rz). The cylinder drum (7) has a plurality of piston bores (8) located concentric to the axis of rotation (Rz) of the cylinder drum (7) and a longitudinally displaceable piston (10) is located in each bore (8). A driving device drives the cylinder drum (7). The drive shaft (4) is a hollow shaft. A torque bar (31) runs through the hollow shaft from a drive flange side end of the axial piston machine (1) to a cylinder drum side end of the axial piston machine (1) to transmit torque from the drive flange side end of the axial piston machine (1) to a cylinder drum side end of the axial piston machine (1).
