发明名称 HYDROSTATIC AXIAL PISTON MACHINE HAVING A CYLINDER BARREL WITH A WORKING PISTON WHICH IS MOUNTED OBLIQUELY WITH RESPECT TO ITS AXIAL DIRECTION AND WITH A PLANAR CONTROL PLATE
摘要 An axial piston machine of swash plate design includes cylinder bores with respective longitudinal axes that are arranged at an acute angle with the rotational axis and that approach the rotational axis radially in the direction of their control plate-side ends. For each cylinder bore, a point of action of a resulting hydrostatic relieving force, which acts on the cylinder barrel, of the hydrostatic sliding bearing is spaced apart radially with regard to the rotational axis of the cylinder barrel further than a point of intersection of the longitudinal axis of the cylinder bore with the cylinder barrel-side bearing face of the hydrostatic sliding bearing.

主权项 1. A hydrostatic axial piston machine of swash plate design, comprising: a cylinder barrel mounted such that it is configured to be rotated about a rotational axis, the cylinder barrel defining a multiplicity of cylinder bores which are delimited in sections by in each case one working piston and, during the rotation of the cylinder barrel, are configured to be connected to high pressure or low pressure via a planar control plate that bears against an end side of the cylinder barrel via bearing faces of a hydrostatic sliding bearing; a swash plate which is mounted pivotably in a pivoting bearing and on which piston shoes arranged at the swash plate-side end of the working pistons slide during the rotation of the cylinder barrel, the longitudinal axes of the cylinder bores being arranged at an acute angle with the rotational axis and approaching the rotational axis radially in the direction of their control plate-side ends, wherein, for each cylinder bore, a point of action of a resulting hydrostatic relieving force, which acts on the cylinder barrel, of the hydrostatic sliding bearing is spaced apart radially with regard to the rotational axis of the cylinder barrel further than a point of intersection of the longitudinal axis of the cylinder bore with the cylinder barrel-side bearing face of the hydrostatic sliding bearing.
