Definitions
- the present invention relates to a hydraulic accumulator and to a method for determining a state of charge of a hydraulic accumulator.
- Hydraulic accumulators are typically used to store large amounts of energy.
- hydraulic accumulators are used to store energy generated, for example, during braking of the wheels, and to release energy required, for example, when accelerating the vehicle.
- Such a hydraulic accumulator is described for example in the document DE 10 2006 060 078 A1.
- hydraulic accumulators are known from the prior art, which have a storage bubble.
- the bladder is usually made of rubber and provides a separation between a gas and a hydraulic fluid in the hydraulic accumulator.
- Such hydraulic accumulators are usually arranged vertically, d. That is, the pressure vessel receiving the hydraulic fluid, the gas and the accumulator bubble extends substantially perpendicular to the ground.
- the hydraulic accumulator defined in claim 1 offers over conventional solutions the advantage that a hose is easy to produce. Furthermore, such a hydraulic accumulator is scalable with little effort, since the hose can be easily adapted in its length. Furthermore, hoses fold in the common in a predictable way, when they are kept in a horizontal position, ie, the hose extends substantially parallel to the ground. Although the folding can lead to damage of the hose over a longer period of time. However, since the folding is predictable, the hose can be designed accordingly to avoid such damage. Accordingly, the hydraulic accumulator according to the invention can also be operated with its hose in a horizontal position.
- the method defined in claim 10 offers over conventional solutions the advantage that the state of charge of a hydraulic accumulator can be determined in a simple manner.
- FIG. 1 is a longitudinal sectional view of a hydraulic accumulator according to an embodiment of the invention.
- Fig. 2 is a section A-A of Fig. 1;
- Fig. 3 is a variation from Fig. 2;
- Fig. 4 is a variation from Fig. 3.
- FIG. 5 is a diagram showing a charging characteristic of the hydraulic accumulator according to FIG. 1. Description of exemplary embodiments
- FIG. 1 shows a hydraulic accumulator 1 according to an embodiment of the invention in a longitudinal sectional view.
- FIG. 2 shows a section A-A from FIG. 1.
- the hydraulic accumulator has a pressure vessel 2. This is dimensionally stable and designed, for example, made of steel.
- the pressure vessel has a main body 4 extending along a longitudinal axis 3 with a substantially annular cross-section, s. Fig. 2, on.
- the main body 4 is formed at its one end with a neck 5.
- the base body 4 is closed by means of a bottom plate 6. Instead of the neck 5, a further bottom plate could also be provided.
- a hose 7 is arranged within the pressure vessel 2.
- the hose 7 is formed of a flexible and elastic material, for example rubber.
- the elasticity of the hose 7 can be advantageously used to influence the charging characteristics of the hydraulic accumulator 1, as described later.
- the tube 7 is made by extrusion. As a result, this can be easily manufactured in any length, so that even longer or shorter hydraulic accumulator 1 can be built easily.
- FIG. 2 In the filled state 7 'of the hose 7, shown in solid line in FIG. 1, this has, as shown in FIG. 2, a basically annular cross section 11.
- the cross section 1 1, however, deviating from a ring shape at opposite locations 12 thickened and formed thinned at opposite locations 13 according to the present embodiment.
- the hose 7 extends through an opening 15 formed by the neck 5 of the pressure vessel 2.
- a plug element 16 is pressed so that the plug element 16 seals against the end 14 of the hose 7 on the inside and also the end 14 of the Hose 7 seals the outside against the opening 15 in the neck 5 of the pressure vessel 2.
- the plug element 16 has a connection 17, by means of which a first medium 18, for example a hydraulic fluid, can be fed to the interior 21 of the tube 7. Furthermore, the hydraulic fluid 18 from the interior 21 by means of the terminal 17 is also discharged again.
- the end 15 opposite end 22 of the tube 7 extends through an opening 23 in the bottom plate 6 of the pressure vessel 2.
- a further plug member 24 is pressed so that it seals the inside against the end 22 of the tube 7 and further seals the end 22 on the outside against the opening 23.
- the plug elements 16 and 24 need not be pressed into the ends 14 and 22 of the tube 7.
- the end 14 may be sealingly bonded or otherwise bonded to the plug member 16 and the opening 15 and the end 22 to the plug member 24 and the opening 23.
- the plug elements 16 and 24 are each formed with a rounding 25 and 26, which bulges into the interior 21 of the tube 7.
- the curves 25 and 26 are intended to prevent damage to the tube 7 or abrasion thereof in its emptied state denoted by 7 "in FIG. 1.
- the curves 25 and 27 are each approximately parallelepiped-shaped additional fixation of the plug 16, 24 in the axial direction, which may be necessary due to the high internal pressure.
- the deflated state 7 "of the tube 7 is also shown in Fig. 2, wherein the tube 7 has a substantially oval cross-sectional shape 27.
- the tube 7 is formed with the previously described thickened and thinned points 12 and 13 respectively.
- the bottom plate 6 of the pressure vessel 2 has a connection 31.
- the con nection 31 allows a supply or discharge of a second medium 30, for example As a gas, in a gap formed between the pressure vessel 2 and the hose 7 32.
- the space 32 is present in the form of an annular space and extends along the longitudinal axis. 3
- pressure vessel for gas can be connected to the port 31 of the pressure vessel 2.
- the hydraulic accumulator 1 according to FIG. 3 differs from that according to FIGS. 1 and 2 only in that the hose 7 is formed with longitudinal grooves 28 on the outside. 3 shows an elastically stretched state 7 "'of the hose 7, which is also shown in Fig. 1. The longitudinal grooves 28 and the hose 7 are shown exaggeratedly large or thick for the purpose of better understanding.
- the hydraulic accumulator 1 according to FIG. 4 differs from that according to FIGS. 1 and 2 only in that the hose 7 is formed with longitudinal grooves 29 on the inside. 4 shows the deflated state 7 "of the hose 7, which is also shown in Fig. 1. The longitudinal grooves 29 and the hose 7 are shown exaggeratedly large or thick for better understanding.
- the energy generated when braking in a motor vehicle can be used to hydraulic fluid 18 through the port 17 of the
- charging characteristic means the course of the pressure in the hydraulic fluid 18 or in the gas 30 as a function of the charge state, ie the degree of filling of the hose 7.
- Charging characteristic means the course of the pressure in the hydraulic fluid 18 or in the gas 30 as a function of the charge state, ie the degree of filling of the hose 7.
- Fig. 5 an increasing pressure in the hydraulic fluid 18 is required to achieve further compression of the gas in the gap 32.
- the pressure progression between the deflated state 7 "and the filled state 7 ' is marked with A in Fig. 5. If hydraulic fluid continues to be supplied, the hose 7 must be elastically stretched in order to move it from its filled state 7' into its elastically deformed state Condition 7 "'to deform.
- This pressure curve B can be influenced by a suitable choice of the elasticity of the hose 7, for example by that it is formed with a thicker or thinner wall and / or of another material.
- the pressure change in a transition region "C" (and / or its first mathematical derivative) between lines A and B may be detected to determine that a state of charge X has been reached.
- the charge state X corresponds to the filled state 7 'of the tube 7.
- hose 7 If the hose 7 is completely filled in its elastically stretched state 7 "', then, as shown in Fig. 3, it rests on the inside against the pressure vessel 2.
- the hose has the longitudinal grooves 28, so that the gas 30 can be distributed uniformly along the longitudinal axis 3 of the hose 7.
- the hydraulic fluid 18 in the gap 32 and the gas 30 may be provided in the interior 21.
- hydraulic fluid 30 would be supplied and removed, for example via the port 31.
- the further, not shown pressure vessel for gas also referred to as gas Nachschaltevolumen could then be connected to the terminal 17.
- plug member 16 and the pressure vessel 2 could be made in one piece and / or the bottom plate 6 and the plug 24 could be one piece.
