Definitions

  • the invention relates to a hydraulic combination unit, comprising a tank, a pump assembly, hydraulic controls, and an electric motor for the pump assembly, which components are arranged coaxially along a straight axis, at most partially overlapping each other.
  • EP 1 302 660 A2 discloses a fuel pump designed as an axial piston pump, which is inserted in a fuel tank of a vehicle.
  • the motor for the pump assembly is designed coaxially with this pump assembly, but the pump itself is incorporated as a unit in the much larger fuel tank, even without specifically entering into a particular geometrical constellation, as it is essential for hydraulic combination aggregates.
  • DE-C3 32 27 926 known to arrange on one side of a base part a pressure-relieved gear pump and the tank and on the other side of the sealed motor encapsulated for the pump. Through a connection opening in the base part and the remaining space in the motor housing interior can be used as a tank volume.
  • the object of the present invention was a combination unit with further reduced dimensions and simpler structure.
  • the higher degree of integration should also increase the profitability of production and thus reduce costs.
  • the invention provides that the pump assembly is formed by an axial piston pump whose cylinder block provided with a plurality of pump elements is oriented coaxially with the other components.
  • the required by the tank anyway axial length of the Combination aggregates are optimally utilized, the diameter but can be kept substantially lower compared to other pump designs, especially in comparison to gear pumps or the radial piston pumps usually used in such aggregates.
  • a further reduction or optimal utilization of the existing construction volume is possible according to a preferred embodiment, according to which the cylinder block is provided along its circumference with magnets and designed as a rotor of the electric motor. A separate from the pump motor can thus be avoided and its construction volume can be saved.
  • the magnetic coils of the electric motor in the housing of the combination unit are arranged around the cylinder block around.
  • the routing and design of the hydraulic elements can be simplified by arranging the tank and cylinder block in relation to the area of the hydraulic controls on the same side, preferably substantially coaxial with each other.
  • a further simplification of the hydraulic line guide is possible by the feature of the invention, according to which the cylinder block is rotatably mounted on a tube, which pipe from the area of the hydraulic controls emanates and extends with a suction in the tank of the combination aggregate.
  • the tank and the region of the housing of the combination aggregate, in which the cylinder block is located are separated by a partition wall.
  • the suction opening for the hydraulic fluid can be moved into an area that can not be swirled or foamed by the rapidly rotating axial piston pump.
  • the tube is mounted in the partition, so that a more stable storage for the cylinder block of the pump can be ensured, which is also the rotor of the electric motor yes at the same time.
  • the well-known advantages of a normally complicated sub-oil engine can be achieved in the combination unit according to the invention by providing in the partition at least one opening below the liquid level and at least one opening above the liquid level, each at normal operating position of the combination aggregate, through which openings the tank with the area of the housing in which the cylinder block is in communication.
  • a motor with high performance in a small size can be used, since the heat is removed via the motor or the cylinder block flushing hydraulic medium.
  • a further improvement of the above construction provides that at least some of the magnetic coils are covered or flowed around by the liquid.
  • the power loss of the windings is easy to dissipate via the hydraulic medium, so that high currents and thus large engine power with a small size are possible.
  • the abovementioned advantages are particularly effective when, in the normal operating position of the combination aggregate, the liquid level in the tank is so high that at least the cylinder block and / or the windings are at least substantially covered by the liquid.
  • the swash plate is mounted on the tube.
  • FIG. 1 shows an axial longitudinal section through a combination aggregate according to the present invention
  • FIG. 2 is a cross-section through the combination aggregate of FIG. 1 along the line II-II.
  • the hydraulic combination unit of FIG. 1 has a region 1 for the hydraulic control elements, which on the one hand forms the bottom of the unit and in a known manner also has kidney-shaped control openings for the adjoining, preferably reversible axial piston pump.
  • the cylinder block 2 of the axial piston pump is pressed against the region 1 in a coaxial arrangement with one of its end faces on which the inlets or outlets of the cylinders 2 a are provided.
  • the cylinder block 2 is rotatably mounted on a hollow tube 3, which pipe 3 starts from the area 1 of the hydraulic controls and projects with a suction opening 3a in the tank 4, 4a.
  • this hollow tube 3 is advantageously coaxial with the area 1 and the cylinder block 2 and the swash plate 5 rotatably mounted, which causes by their relative to the front side of the cylinder block 2 inclined front axial movement of the guided in the cylinders 2a piston 6 of the axial piston pump.
  • the cylinder block 2 of the axial piston pump four magnets 7 are provided, so that this cylinder block 2 is simultaneously the rotor of a brushless electric motor.
  • the respective windings of the magnetic coils 8 are arranged around the cylinder block 2 inside the housing 9 of the combination aggregate. It is therefore not separate electric motor for the axial piston pump necessary, but it is itself, together with the magnetic coils 8, their own motor.
  • the magnetic coils 8 and the swash plate 5 are connected to the region 1 of the hydraulic control elements by a common support structure 18 into one unit.
  • the housing 9 of the combination unit can be made thinner and lighter, because the mechanical strength is effected to a large extent by this support structure 18.
  • the region 4a of the axial piston pump 2, 2a, 5, 6 is separated from the region 4 of the tank by a dividing wall 10 into which the suction opening 3a of the tube 3 protrudes.
  • this partition 10 holes 11 or similar through openings are provided, through which the area 4a with the axial piston pump and the area 4 are in communication, so that hydraulic fluid is up to a liquid level 12 in both areas.
  • the level 12 of the hydraulic fluid is so high that at least one of the holes 11a is located in the air-filled area of the tank 4, 4a.
  • a board 15 with the control electronics used which also takes over the lines, the control of the windings 8.
  • the power supply and any control signals are accomplished via the central terminal 17 and fed.
