Claim:
1. A hydrostatic axial piston machine utilizing a bent-axis construction, comprising: a drive shaft rotatable around an axis of rotation and provided with a drive flange; a cylinder drum rotatable around an axis of rotation offset from the axis of rotation of the drive shaft; a plurality of piston bores located in the cylinder drum and concentric to the axis of rotation of the cylinder drum; a longitudinally displaceable piston located in each piston bore, wherein the pistons are fastened in an articulated manner to the drive flange; and a driving joint between the drive shaft and the cylinder drum for rotationally synchronous rotation of the cylinder drum and of the drive shaft, wherein the driving joint comprises a cone-beam semi-roller joint, wherein the cone-beam semi-roller joint comprises at least one roller pair with two semi-cylindrical half-rollers, wherein the semi-cylindrical half-rollers are flattened along an axis of rotation separate from the axis of rotation of the drive shaft and the axis of rotation of the cylinder drum and the half-rollers form flat sliding surfaces on the flattened sides at which the half-rollers of the roller pair are in contact with each other to form a contact surface.
