1. An axial piston machine with a plurality of reciprocating pistons, each of which can move longitudinally in a cylinder bore and is supported on a bearing surface of a drive plate, whereby the drive plate is oriented so that it forms a tilt angle with a transverse plane that is perpendicular to the axis of rotation of the axial piston machine, wherein the bearing surface is provided with a concave curvature when viewed in the direction of the longitudinal center plane of the axial piston machine, at least in the vicinity of the reciprocating piston that extends farthest out of the cylinder bores, wherein the curvature of the bearing surface provides that the surface pressure of the reciprocating pistons in the cylinder bores that occur during operation differ from each other by not more than 20%.
