Definitions

  • the invention relates to a hydraulic accumulator having at least two housing shells in the form of rotational bodies with respect to the longitudinal axis of the storage housing and with at least one fuel element which preferably separates media inside the housing formed by the housing shells from one another, wherein the housing shells with their free end faces to form the storage housing are in juxtaposition, and wherein the individual housing shells are connected to each other in a pressure-tight manner by means of an externally applied Faserumwicklung or at least one applied Fasergeleges.
  • the DE 10 2006 004 120 A1 also discloses a hydraulic accumulator in the form of a diaphragm accumulator, in which, in addition to metallic housing parts which each form a connection region on the gas side and on the fluid side of the accumulator, a reinforcing winding of a fiber material is provided as a further housing component.
  • hydraulic accumulators have to meet different requirements. Particularly high demands are to be met if such accumulators are used in hydraulic systems of sophisticated motor vehicles. This is particularly the case when it is intended to be used in competition vehicles, such as Formula racing cars. In these cases, the respective hydraulic accumulators must not only cope with high loads, both in terms of mechanical loads, static and dynamic nature, including extremely high pressure loads, but it is also imperative that the reliability, despite the high load, with the lowest construction weight of the memory is reached.
  • a hydraulic accumulator of the type mentioned is out GB 948,675 A known.
  • the membrane arranged within the storage housing has on the outer peripheral side a connection region which is shaped such that the opening edges of the housing shells can each engage in an annular groove.
  • the housing shells in the connected state are spaced apart from one another at the end by the membrane arranged therebetween, the membrane additionally ensuring a fluid-tight separation of the two working spaces provided in the accumulator housing.
  • the invention has the object to provide a hydraulic accumulator of the type considered available, which, although he is able to cope with the mentioned, high loads, characterized by a minimum construction weight.
  • a significant feature of the invention is that the mutually facing opening edges of the preferably metallic housing shells overlap each other such that the effective in the overlap area, generated by the convolution formed from a fiber composite material supporting force and this counteracting, generated due to internal pressure in the storage enclosure pressure force a Clamping force in the overlap area as a holding force for the mutual anchoring of the opening edges of the shells form.
  • This type of mutual anchoring ensures the simplest design and lowest construction weight pressure resistance of the housing at very high operating pressures, for example, at pressure peaks up to 250 bar or more, even at low wall thickness of the shells, due to serving as an abutment outer support by wrapping the internal pressure reinforced in the storage housing, the clamping forces against the counter-bearing formed by the winding.
  • the housing shell forming the housing shells are pressure-tightly connected to one another at their mutually facing end sides by means of an externally applied wrapping made of a fiber composite material or by means of a Fasergelegecitedes.
  • the arrangement according to the invention is such that the opening edge of that housing shell, which is radially inwardly in the overlap region, forms an approximately C-shaped hollow profile for receiving the at least one separating element.
  • the arrangement is such that the opening edge of the housing shell in the overlap region or at the overlapping point radially outer shell to form a paragraphless transition of the outer surface of the two housing shells rests against an annular surface which is formed by a step which is provided at the opening edge of the other housing shell at the transition to the hollow profile. This results in not only a formed by the outside of the wrap, paragraphless, smooth outer contour of the storage enclosure, but the housing shells are additionally secured against a relative axial movement directed against each other.
  • the movable separating element may be formed by a membrane whose peripheral edge engages in the overlapping region with an anchoring part between the opening edges of the housing shells so that the clamping force acting in the overlapping region forms the holding force for anchoring the anchoring part of the membrane to the opening edges of the housing shells ,
  • the clamping force acting in the overlapping area is simultaneously available as a holding force for the anchoring of the membrane, which leads to a particularly significant simplification of the construction.
  • the anchoring part at the peripheral edge of the membrane can preferably be formed by a thickened edge bead of the membrane, which thus forms a kind of sealing ring at the anchoring point.
  • the hollow profile preferably forms a radially inwardly and at a distance thereof radially outwardly extending legs, between which the edge bead of the membrane can be accommodated, on its outer side at the Inside the overlapping opening edge of the other housing shell rests.
  • the housing shells are formed from an aluminum alloy, resulting in a particularly low weight despite high load capacity.
  • the terminals of the housing shells are formed by coaxial to the longitudinal axis, integrally formed connection body to which the wall of the respective housing shell with respect to the thickness of the connecting body of reduced wall thickness connects.
  • Particularly good strength properties result when the wrapping forms a thickening in the region of the transition between connection body and reduced wall thickness of the housing shell.
  • the wrapping also acts as a reinforcement of the relevant connection body against acting during operation on him load forces or vibrations.
  • the wrapping may be formed of a material containing carbon, Kevlar ® -, glass, boron, Al 2 O 3 fibers or a mixture containing thereof.
  • an approximately pear-shaped to a longitudinal axis 3 rotationally symmetrical storage housing is designated as a whole with 1.
  • This has, arranged concentrically to the axis 3, a connection body 5 and a connection body 7, wherein the connection body 5 an inlet 9 for filling the adjoining gas side 11 with a working gas, preferably N 2 , while the connection body 7 has a fluid inlet 13 as Connection with a fluid side 15 forms.
  • these metallic housing parts each form a rotationally symmetrical to the axis 3, thin-walled shell, wherein the top in the drawing shell 17 and the underlying shell are designated 19.
  • the overlapping region 21 of the shells 17 and 19 is designed so that in the transition region 21, a membrane 33 formed of elastomeric material is both mechanically fixed to the storage housing 1 with its peripheral edge and forms a seal between the gas side 11 and the fluid side 15.
  • the membrane 33 has in this regard a peripheral edge bead 35, which is clamped between the opening edge 25 of the outer region 21 on the overlapping region 21 and the opening edge 23 of the inner shell 17.
  • the opening edge 23 of the upper shell 17 forms a radially inwardly drawn hollow profile approximately C-shaped configuration, with a radially inwardly extending leg 37 and an axial distance from this, radially to outside striving leg 39, which overlap between the edge bead 35 of the membrane 33, the outside of the smooth-surface opening edge 25 of the lower shell 19 abuts.
  • This configuration of the overlapping region 21 not only results in a mechanically secure and fluid-tight clamping of the membrane 33 at its thickened bead 35, but also leads to a clamping of the overlapping end edges 23, 25 of the shells 17 and 19.
  • the upper shell 17 forms on Transition to the hollow profile, a step 41 for forming a radially retracted annular surface on which the smooth-surfaced opening edge 25 of the lower shell 19 is applied so that the transition of the two shells 17 and 19 on the overlap region 21 on the outside is without offset, so that the reinforcing wrap 27 at her Outside one also in the overlap region 21 smooth-surfaced, choppy contour forms.
  • the step 41 also forms a backup of the shells 17 and 19 against a mutually directed axial movement due to the generated by the wrapping 27, acting on the shells 17, 19 supporting force.
  • a formed from a fiber composite wrap 27 which may be designed in a conventional manner, therefore, results in conjunction with shells formed from an aluminum material 17, 19 a very high pressure resistance and reliability in the simplest design and in particular at a minimum in construction weight.
  • the reinforcing wrap 27 may be formed from a fiber reinforcement such as carbon, aramid, glass, boron, ALO 3 fibers or mixtures thereof.
  • these fibers are embedded in a base matrix of thermosets, such as epoxy or phenolic resins, or in thermoplastics.
  • FIG. 3 shown embodiment differs from the example first described basically only insofar as at the transition regions 29, 31 between the connecting bodies 5 and 7 and the adjoining thin-walled portion of the shells 17, 19, wherein in Fig. 3 only the transition region 29 is shown on the shell 17, the wrapping 27 each forms a thickening region 45.
  • This thickening region conforms to an axially extending, cylindrical outer surface 47 of the respective connection body 5, 7 in such a way that the winding 27 surrounds a connection body 5, 7
  • Reinforcing ring forms, which supports the respective connection body 5, 7 relative to the thin-walled shell part and thus forms a reinforcement of the connection body 5 and 7 relative to the rest of the storage housing 1, whereby mechanical, static or dynamic, acting on the connection bodies 5, 7 forces in the reinforcing wrapping 27 are introduced, resulting in a particularly high level of operational reliability under heavy loads, as they can occur, for example, in competition vehicles in racing.
  • the winding has been optimized insofar as a substantially constant thickness is maintained along the circumference of the housing.
  • the winding is chosen differently from the width or thickness, in particular the thickness of the winding increases in the direction of the upper terminal. In such a way, however, it is also possible to compensate for these at places of high stress by an increasingly applied winding.
