Definitions

  • the invention relates to a hydraulic accumulator in the form of a piston accumulator, with the features in the preamble of claim 1.
  • Hydraulic accumulators are in the prior art, for example, by DE 103 10 427 A1 known, in which the piston part in particular separates a space with a working gas, such as nitrogen, from a space with a working fluid, such as hydraulic oil, are known in a variety of sizes and designs and are available on the market. They are widely used in hydraulic systems of the most varied types, for example for storing hydraulic energy, for damping or smoothing pressure fluctuations or the like. In many cases, storage devices in the form of piston accumulators are also used in hydraulic systems in work equipment that have hydraulic drive units, for example in mobile work machines such as excavators, forklifts, loaders or mobile cranes.
  • the DE 37 28 555 A1 describes a hydraulic accumulator, in particular a piston accumulator, in which a piston part separates two media spaces within a storage housing, the piston part in one Hollow or running tube is guided within the storage housing in each of its possible displacement positions, and wherein the running tube is fixed with its overhead end on the cover part.
  • the FR 1 299 239 , the GB 2 486 051 A and the DE 10 2005 015 262 A1 show pressure accumulators with deep-drawn pistons.
  • an essential feature of the invention is that the piston part is designed as a deep-drawn part and that to fix the barrel, the end edge of the cover part has a seat for the barrel with a tolerance sleeve and an O-ring seal on the inside.
  • the design as a deep-drawn part also leads to a comparatively low piston weight and, because of the low mass inertia, to favorable operating behavior.
  • the piston part can be divided into a guide part and a dome-like trough part, which is used to enlarge the gas working space on the gas side of the storage tank, with a pressure-balanced separating surface between the two media spaces during operation of the storage tank being formed by the trough part.
  • a particularly large proportion of the total volume of the storage housing is advantageously available as gas volume.
  • the piston part can be provided on the outer circumference with continuously encircling, groove-like depressions for receiving sealing and guide bands.
  • the respective groove-like depressions can be obtained in a particularly advantageous and rational manner by a roller burnishing process, which can be carried out in a particularly efficient manner as an additional forming step in connection with the deep-drawing.
  • the arrangement can be made such that one of the groove-like depressions for receiving the guide band is arranged on a free end area of the piston part within the guide part, with a further second groove-like depression serving to accommodate the sealing band and in the area of the transition between the guide and the trough part is arranged either on the guide or on the trough part.
  • the axial distance between the guide band and the sealing band ensures particularly favorable, tilt-proof guidance of the piston part.
  • the wall thickness of the piston part designed as a hollow piston is advantageously essentially the same over its axial extent.
  • the length of the cylindrical guide part is preferably equal to or greater than half the diameter of this guide part.
  • the piston part can be formed from a fine-grain sheet, in particular from a stainless steel material or an AlMg alloy, or from another metallic material suitable for a deep-drawing process.
  • the piston part is guided in a hollow tube within the accumulator housing in each of its possible displacement positions.
  • An additional advantage is that a structurally identical unit, consisting of a hollow tube and associated piston part, can be used for different accumulator housing sizes, whereby a modular design can be implemented for the production of differently dimensioned hydraulic accumulators, which enables particularly efficient production at low cost.
  • the accumulator housing does not have to be made of a metallic material that offers good sliding properties for the piston part, but that composite materials, for example in the form of carbon fiber-reinforced plastic materials, can also be used, which makes the production of particularly lightweight hydraulic accumulators inexpensive Way allows.
  • Hydraulic accumulator not shown according to the invention in the form of a piston accumulator has an accumulator housing 1 with a circular cylindrical housing main part 3, a housing cover part 5 and a bottom part 7.
  • the main housing part 3 and the bottom part 7 form a pot which is closed except for a gas filling connection 11 located coaxially to the storage longitudinal axis 9.
  • the main housing part 3 and the bottom part 7 are made in one piece, for example in the form of a deep-drawn part made of metallic material, the bottom part 7 having a convex curvature on the outside.
  • an AlMg alloy is provided as a material suitable for deep-drawing for the housing main part 3 and base part 7, with a wall thickness of the main part 3 of 3.3 mm.
  • the storage housing can also be constructed differently, for example in the form of a so-called liner which is at least partially wound from plastic laminate materials.
  • the housing cover part 5 has the shape of a shell with a concave inside 13 and, as a closure part of the housing 1, is connected to the opening edge by means of a bead 15, with an O-ring 17 in an annular groove 19 formed on the edge of the cover part 5 Forms seal.
  • a fluid connection 21 for a relevant working fluid such as hydraulic oil, is provided on the cover part 5.
  • Connection fittings on the fluid connection 21 as well as on the filling connection 11 are designed in accordance with the prior art.
  • a piston part 27 is guided in the main housing part 3 in an axially freely movable manner.
  • This piston part 27 is formed by a one-piece deep-drawn part, a fine-grain sheet suitable for the deep-drawing process being provided, for example an AlMg alloy or a stainless steel material.
  • the Fig. 1 shows the preform 26 formed after deep drawing, from which the finished, in Fig. 2 piston part 27 shown is formed by roller burnishing.
  • the piston part 27 has a bowl-like or pot-like shape with a guide part 29 extending axially along the inside of the main housing part 3, at whose end facing the cover part 5 a trough part 31 connects, which is arched like a dome.
  • the curvature of the trough part 31 is adapted to the concave curvature of the inside 13 of the cover part 5 so that the piston part 27 rests over the entire surface on the inside 13 in its upper end position, ie when there is no fluid pressure in the fluid working space 25. In this end position, the storage housing 1 is thus free of a residual volume of remaining fluid.
  • the separating surface 33 formed by the trough part 31 between the gas working space 23 and the fluid working space 25 is pressure-balanced.
  • the trough part 31, like the guide part 29, can therefore be designed with a smaller thickness, so that the piston part 27 is a deep-drawn part with a low structural weight represents and the correspondingly low inertia leads to a favorable operating behavior, for example when used as a pulsation damper.
  • the piston part 27 is provided on the outer circumference with continuously encircling, recessed grooves 35 and 37. These grooves 35, 37 are each formed by roller burnishing the preform.
  • the overhead groove 35 in the figure is located at the transition between the guide part 29 and the trough part 31 and forms the seat for a sealing ring 39 .
  • the axial length of the cylindrical guide part 29 is at least half the diameter of the guide part 29.
  • the axial distance thus formed between the guide band 41 and the sealing ring 39, the piston part 27 is optimally guided in a tilt-proof manner.
  • the wall thickness of the piston part 27 is essentially constant throughout.
  • the hydraulic accumulator of the first exemplary embodiment according to the invention from Fig. 4 is intended for a higher pressure level, for example for a design pressure of 350 bar.
  • the storage housing 1 with the main part 3 and cover part 5 is formed from a suitable stainless steel.
  • Another difference compared to the embodiment of Fig. 3 consists in that the piston part 27, as in Fig. 3 is formed from a one-piece deep-drawn part, is not guided directly on the inside of the housing.
  • a running tube 47 is provided as a guide device, which extends concentrically to the axis 9 in the main housing part 3.
  • the running tube 47 is formed with a small wall thickness, for example 2 mm, from a metallic material, such as an AlMg alloy, and is fixed to the cover part 5 with the end located at the top in the figure. The end edge forms for this
  • the inside of the cover part 5 has a seat for the barrel 47 with a tolerance sleeve 49 and an O-ring seal 51 with passages (not shown) supported on the main housing part 3 without a seal being formed.
  • the space 55 between the running tube 47 and the main housing part 3 is therefore part of the gas working space 23.
  • the storage housing 1 can be manufactured particularly inexpensively.
  • the unit made of barrel 47 and piston part 27 can be prefabricated as a module or building block for different storage designs and sizes. If necessary, with the same pipe diameter and the same piston part 27, different pipe lengths can be provided for different lengths of the accumulator housing 1.
  • the embodiment of Fig. 5 also relates to a piston accumulator for a higher pressure level, for example a design pressure of 350 bar.
  • a higher pressure level for example a design pressure of 350 bar.
  • the main housing part 3 is made thin-walled.
  • the main part 3 is a deep-drawn part with a wall thickness in the circular cylindrical length section of 5 mm, only the bottom part 7 and the end section 57 forming the connection with the cover part 5 having a greater wall thickness.
  • the main part 3 is surrounded by a cylindrical jacket 59. This is formed from a high-strength composite material, for example from a carbon fiber reinforced plastic material.
  • a piston accumulator in what is known as a liner design can be realized which, despite high compressive strength, has a particularly low structural weight and, thanks to the piston part 27 formed as a lightweight deep-drawn part, has good operating behavior and can also be produced particularly efficiently and inexpensively.
