Abstract
An axial piston machine with a swashplate and a cylinder block provided with a torque transmission member is rotationally mounted by a bearing system located radially between the cylinder block and a housing. To achieve compact dimensions and an improved supply of hydraulic fluid, the cylinder block and the swashplate are penetrated centrally by two plain coaxial conduits that are connected on the swashplate-side ends to hydraulic fluid supply channels and emerge on the cylinder-block-side ends in a control body which has a control surface that interacts with the cylinder block. The control body is located inside the cylinder block. The plain conduits are supported in a swashplate mounting and in the cylinder block. The axial piston machine is preferably realized in the form of a wheel motor.
Claims19
