Abstract:
The invention relates to an axial piston machine, in addition to a swash-plate for said machine and a method for producing a swash-plate. The swash-plate (24) is configured as a disc and has a central bore (32), which is encompassed by a collar (39), extending in an axial direction from a first surface (34, 34′) of the swash-plate (24). In addition, the swash-plate (24) has several sliding block receiving openings (36), each of the latter (36) being encompassed by a guide collar (38), which extends in an axial direction from a second surface of the swash-plate (24), in the opposite direction to the collar (39) of the central bore (32).
Abstract:
The invention relates to a hydrostatic axial piston engine with a cylinder drum (106) which is mounted rotatably in a housing (103). Longitudinally displaceable working pistons (111) are disposed in cylinder boreholes (110) in the cylinder drum (106). The working pistons (111) are connected movably to sliding blocks (149) and are supported on a face (116) of an inclined disk (115). Furthermore, the hydrostatic axial piston engine (101) has a control piston (126) which interacts with the inclined disk (115) for adjusting an angle of inclination of the face (116) with respect to an axis of rotation (144) in the cylinder drum (106). The control piston (126) is supported over a control piston sliding block (149′) on the face (116) of the inclined disk (115) in order to exert a regulating force on the inclined disk (115).

Abstract:
The invention relates to a control plate (20) for an axial piston engine (1). The inventive control plate (20) comprises a through hole (38) and a radial internal edge of said control plate (20) embodied in the form of a centering surface (29) which centers the control plate (20) to a centering body (7) arranged on the side of a bearing surface. Said centering surface (29) consists of several partial surfaces (29.1, 29.2, 29.3) formed on segments (43.1, 43.2, 43.3) of the internal edge (47) of the control plate (20) radially extending towards the internal space of said through hole (38). The segments (43.1, 43.2, 43.3) are divided by cuts (36.1, 36.2, 36.3).
Abstract:
The invention relates to an axial piston machine (1) having a rotatably mounted cylinder drum (5) which in turn has a center recess (38) and a plurality of cylinder bores (6) that extend substantially axially relative to the center bore (38) and in which pistons (7) are movably guided and are supported on a pivoting plate (11) via sliding shoes (8). Said sliding shoes (8) are guided in recesses (23) of a withdrawal plate (22) in whose contact inner bore (25) a withdrawal body (26) is guided with an outer surface that corresponds to the inner bore (25) of the withdrawal plate (22). The withdrawal body (26) is subject to an axially directed pretension force which is exerted by a tension spring (26) via the pressure pins (28). Every pressure pin (28), on its base side (40), is provided with an enlarged portion (43) radially in relation to its longitudinal axis (34).
Abstract:
A fastening member to be driven into a hard receiving material, such as concrete, masonry, rock and the like, has an axially extending shank with a drilling head at its leading end and a thread adjacent its trailing end for connecting a load to the fastening member. A device is located on the shank for engagement with a tool for driving the fastening member into the receiving material. Initially, the fastening member drills a blind bore into the receiving material and then an explosive powder charge drives the member into its final position.
Abstract:
An axial piston machine comprises a cylinder drum in which a multiplicity of pistons are arranged in a longitudinally displaceable manner. The pistons are supported, via sliding blocks, on a running surface which is inclined relative to the cylinder drum axis. The sliding blocks are held, at that side thereof which faces away from the running surface, by means of a retraction plate. The retraction plate is produced from processed sheet metal in a non-cutting punching and stamping process.
Abstract:
Piston engine with a housing in which a shaft (19) is rotatably mounted in two pivot bearings of which at least one pivot bearing has an inner ring (26a) which is seated without radial clearance of motion on a supporting region (28) of a bearing section (19c) of said shaft (19). In order to prolong the working life of the at least one pivot bearing, the axial length of the supporting region (28) corresponds to a central region (a) of the bearing section (19c), a radial clearance of motion being disposed, at the two outer regions (b, c), between said outer regions (b, c) and the inner ring (26a).
Abstract:
The invention relates to a tubular piston for a piston engine, comprising a tubular section, a collar shaped region and a ball pivot formed thereon, and an inner tube arranged in an outer tube. A cavity is at least partially formed between the outer tube and the inner tube. Said cavity is sealed from the area surrounding the hollow piston in a pressure-tight manner, by a material, especially a solder material, which is arranged in the cavity in a positively locking manner by means of heating.
Abstract:
The invention relates to a piston for a hydrostatic machine and a corresponding production method. In a conventional production method of this type, the piston is shaped from a blank into a shank section and a ball and socket joint section connected to the shank section by means of a neck section. According to the inventive embodiment, an additional blank for an inner tube is inserted into the blank of the outer tube before the latter is shaped. A hollow piston comprising one or more hollow chambers between the inner and outer tubes is formed after both blanks have been shaped.
