Embodiment Construction

[0032] exist figure 1 The axial piston machine 2 shown in, for example, configured for a flat configuration of the bearing surface with a cylinder barrel and an oil distribution plate, as well as an arrangement of cylinder bores and working pistons arranged obliquely to the axis of rotation of the drive shaft, comprises a housing 4, A swash plate 8 , a cylinder barrel 10 with its axis of rotation 12 and an essentially flat oil distribution plate 34 , also called distribution plate or distribution plate, follow axially successively in the interior 6 of the housing. There is a drive shaft 62 with its axis of rotation 70 penetrating the distributor plate. The cylinder barrel 10 is arranged coaxially with the drive shaft 62 and is coupled non-rotatably relative thereto via a rotary linkage 68 , for example in the form of a toothed coupling. The cylinder bore 10 rests with its end facing away from the swash plate 8 against the oil distribution plate 34 via an annular hydrostatic p...

Abstract

The invention relates to an axial piston machine designed as a swash plate, the longitudinal axes of the cylinder bores being arranged at an acute angle to the axis of rotation and radially approaching the axis of rotation in the direction of their oil plate-side end. According to the invention, for each cylinder bore, the points of action of the hydrostatic unloading forces generated by the hydrostatic plain bearing acting on the cylinder barrel are radially spaced apart from the cylinder bore relative to the axis of rotation of the cylinder bore The intersection point of the longitudinal axis of the hydrostatic slide bearing with the cylinder bore-side bearing surface is farther away.

Description

technical field [0001] The invention relates to a hydrostatic axial piston machine which can be designed as a hydraulic pump or a hydraulic motor or can be operated not only as a hydraulic pump but also as a hydraulic motor. Background technique [0002] Axial piston machines are known in which the cylinder barrel and the oil distribution plate, also called distribution plate or distribution plate, rest against a flat bearing surface and the cylinder bore or the working piston movably mounted therein is parallel to the drive shaft The axis of rotation is arranged as shown in DE 10 2010 006 895 A1. It is also known that the bearing surfaces of the cylinder barrel and the oil distribution plate are configured spherically and that the cylinder bore and the working piston are arranged parallel to the axis of rotation of the drive shaft, as in DE 34 13 059 C1 ( figure 1 ) or as shown in DE 197 06 263 C1. Furthermore, it is known that the bearing surfaces of the cylinder barrel ...
