Abstract: A hydraulic axial piston motor (1) is disclosed, having a rotatable cylinder drum (4), in which several work pistons (6), each provided at one end with a slider shoe (7), are arranged in work cylinders (5) so as to be axially movable, having a control plate (11), a swash plate (8), against which the slider shoes (7) bear, a pressure plate (9) which holds the slider shoes (7) on the swash plate (8), and a pressure-applying unit, which acts on the pressure plate (9) and comprises a hydraulic piston-cylinder arrangement (12, 13). Using such a motor it is desirable for an adequate contact pressure to be produced using simple means. For that purpose, the piston-cylinder arrangement (12, 13) is arranged between the cylinder drum (4) and the control plate (11).

Abstract: A radial journal bearing (5, 6) is indicated, with an interior bearing surface placed facing an exterior bearing surface, where one of the bearing surfaces comprises a slide shoe (7, 8), which has one end with a contact face loaded to contact against the other bearing surface, and where this end is movable in such a manner that the contact against the other bearing surface can be maintained by a relative displacement of the bearing surface at right angles to the direction of the load. Hereby it is achieved that the variation of the leakage between the slide shoe and the opposing bearing surface is essentially reduced, resulting in longer life and greater stability.

Abstract: A hydraulic machine with a piston and slider shoe unit (1) is disclosed, in which the piston (2) and the slider shoe (3) are joined to one another by way of a ball-and-socket joint (4) forming a first contact surface, and the slider shoe (3) lies via the intermediary of a second contact surface on a control surface (9), a friction-reducing layer being arranged on one contact surface. It is desirable for a hydraulic machine of that kind to be capable of reliable operation even when using hydraulic fluids having only a poor or no lubricating effect at all, yet to be inexpensive to manufacture. For that purpose, the friction-reducing layer (11) is extended to at least one further contact surface.

Abstract: A hydraulic axial piston motor (1) is disclosed, having a cylinder drum (4) which is connected, so that it is non-movable axially, to a shaft (3) and so that they rotate together, and which has at least one cylinder (5), for each cylinder a piston (6) arranged in the cylinder, which piston bears at its end projecting from the cylinder drum (4) against a swash plate (8) via the intermediary of a slider shoe (7), a pressure-applying arrangement (9) for holding at least one slider shoe (7) against the swash plate and a control plate (12) with control kidneys. It is desirable for such a motor to be reliably operable even when the shaft is provided with axial play. Leakages in particular are to be avoided. For that purpose, the pressure-applying device (9) is mounted so as to be axially movable relative to the cylinder drum (4). A pressure plate (13) that is axially movable relative to the cylinder drum (4) is arranged between the control plate (12) and the cylinder drum (4), this pressure plate having for each cylinder a through-opening (14) which is connected in a fluid-tight manner to the cylinder (5). Furthermore, between the pressure-applying device (9) and the presssure plate (13) there is provided an expanding device (18) which acts on the pressure-applying device (9) and the pressure plate (13) with oppositely directed forces.
