摘要： A multiple-stroke hydrostatic axial piston machine has a plurality of piston-shaped displacement bodies (13) that can each move longitudinally in a displacement chamber (12) and are each supported by a roller body on a track (9) that is provided with axial cams (10) that generate a reciprocal motion. Each of the roller bodies is a roller (14) which is located in a recess (A) of the displacement body (13) that restricts radial and axial relative movements of the roller (14) with respect to the displacement body (13). The displacement body (13) can be configured as a cage of the roller (14).

摘要： A drive axle, in particular an industrial truck drive axle, has an electric motor (2), a differential (4) of a traction drive, which differential is oriented coaxially with the electric motor, and a planetary gear set (3) that is connected between the electric motor (2) and the differential (4). To reduce the effort and expense required to construct the drive axle, the electric motor (2) can be connected in a drive connection by means of a coupling device (5) that is in an operative connection with the planetary gear set (3), with the traction drive, and/or with a work drive. The electric motor (2) can thereby feed a work drive alternatively or in addition to the traction drive.

摘要： An axial-piston machine such as an axial-piston motor or, preferably, an axial-piston pump, has a cylinder drum rotatable in a chamber defined by the machine housing, the cylinder bores at low pressure communicating with the interior of the housing. Only part of the end of the cylinder drum turned toward a displacing slide covers the surface of this slide which is provided with an arcuate groove for communication with the cylinder bores under elevated pressure while the control surface of this slide only covers the high-pressure portion of the surface of the cylinder drum so that the latter overhangs the slide.

摘要： An axial-piston machine of the type in which a prismatic housing, usually of rectangular or square cross section, receives a rotatable cylinder drum, the pistons of which bear against an inclinable control surface. The control surface is formed on a rocker or tilting box which can be tilted about an axis perpendicular to the axis of rotation of the drum. The rocker-setting elements are disposed between the housing bottom and the reaction surface of the rocker (against which the pistons bear), at the corners of a rectangle which closely circumscribes the orbit of the pistons. Consequently, the presence of the rocker-displacing means does not increase the dimensions of the machine over those necessary for a fixed control surface machine.

摘要： An axial piston machine with a variable or adjustable stroke comprises a rotatable cylinder drum provided with annularly spaced cylinder bores each of which receives a piston reciprocal in its bore parallel to the axis of rotation of the drum and with a stroke determined by the extent of tilt of a guide surface about an axis perpendicular to the axis of rotation of the drum. The piston stroke is controlled by a rocker carrying the control surface and hydraulically displaceable in the machine housing by application of hydraulic fluid pressure directly to the rocker.

摘要： An axial piston motor utilizing swash plate construction, in particular a wheel motor, includes a stationary support part that contains a swash plate, a control surface and a rotating output part into which a cylinder drum is integrated. Common bearings are provided for mounting the cylinder drum and the support part. The bearings are located radially between the cylinder drum and a bearing bush that surrounds the cylinder drum and is connected with the rotating output part. The bearings, which are preferably roller bearings, absorb both the external forces (wheel loads) and also the engine forces.
