[0004] The fundamental problem of this invention is to provide a damping system that is smaller, lighter, and less expensive than existing systems. [Means for solving the problem]

[0005] The above problem is solved by the damping system described in claim 1. Advantageous embodiments are the subject of the dependent claims.

[0006] The damping system comprises at least one fluid damper containing a damping volume that encloses a damping fluid. The damping fluid is preferably a liquid, particularly a hydraulic fluid. The damping volume is preferably completely filled with the damping fluid.

[0007] The damping system comprises a fluid reservoir including a reservoir piston that divides the internal volume of the fluid reservoir into a damping chamber containing damping fluid and a reaction chamber containing reaction fluid. The reaction fluid is preferably a gas, particularly air. The reaction chamber is preferably completely filled with the reaction fluid. The above division is preferably designed to be fluid-sealed.

[0008] The damping volume of at least one fluid damper is connected to the damping chamber of a fluid reservoir to allow fluid to flow through. For example, the fluid reservoir may be directly attached to at least one fluid damper, allowing for direct connection of the damping volume of at least one fluid damper to the damping chamber of the fluid reservoir.

[0009] The reservoir piston is movable in the compressive direction, increasing the volume of the damping chamber and decreasing the volume of the reaction chamber. When the reaction chamber is filled with a compressible reaction fluid, the reaction fluid is compressed when the reservoir piston moves in the compressive direction. As a result, the pressure of the compressed reaction fluid forces the reservoir piston to move in the expansion direction, pushing the damping fluid from the damping chamber of the fluid reservoir into the damping volume of at least one fluid damper. Thus, the fluid reservoir functions as a gas spring in series with at least one fluid damper.

[0010] The reservoir piston is movable in the expansion direction, which decreases the volume of the damping chamber and increases the volume of the reaction chamber. When the reaction chamber is filled with a compressible reaction fluid, the reaction fluid expands as the reservoir piston moves in the expansion direction.

[0011] The compression and expansion directions are preferably oriented in opposite directions along the linear longitudinal axis of the fluid reservoir, and the reservoir piston is capable of linear motion along this longitudinal axis. In an alternative embodiment, the reservoir piston is capable of motion by rotation around a rotation axis or by elastic deformation of the reservoir piston.

[0012] The reservoir piston of the fluid reservoir preferably includes a damping chamber surface facing the damping chamber and a reaction chamber surface facing the reaction chamber. The surface area of ​​the damping chamber surface is preferably smaller than the surface area of ​​the reaction chamber surface. For example, the damping chamber surface and the reaction chamber surface of the reservoir piston may be disc-shaped, and the damping chamber surface has a shorter diameter than the reaction chamber surface.

[0013] Due to their differing surface areas, the reservoir piston can function as a pressure transfer device, converting the smaller pressure of the reaction fluid acting on the reaction chamber surface into a larger pressure on the reservoir piston acting on the damping fluid through the damping chamber surface. As a result, a lower pressure of the reaction fluid can be used for a given application of the damping system. Lower pressure of the reaction fluid relaxes the requirements for the mechanical stability and fluid sealing of the fluid reservoir, allowing for a smaller, lighter, and less expensive design for the fluid reservoir. [Brief explanation of the drawing]

[0014] [Figure 1] This figure shows a schematic longitudinal cross-section of the fluid reservoir of the damping system according to the present invention. [Figure 2] This is a schematic diagram of the damping system according to the present invention. [Figure 3] This is a schematic diagram of another damping system according to the present invention. [Modes for carrying out the invention]

[0015] The damping system preferably includes a fluid conduit that connects the damping volume of at least one fluid damper to the damping chamber of a fluid reservoir to allow fluid to flow through. This conduit allows the fluid reservoir to be positioned away from at least one fluid damper, enabling more efficient use of the space available for installing the damping system. At least one section of the conduit, particularly the entire conduit, is preferably flexible. The conduit may include, for example, a hose. When the conduit is flexible, the damping system can be more easily positioned in a limited space.

[0016] The damping system preferably includes a pump connected to the reaction chamber of a fluid reservoir to regulate the pressure of the reaction fluid in the reaction chamber. This pump may be manually operated, for example. This pump is preferably electrically operated, and more preferably computer-controlled. By regulating the pressure of the reaction fluid, the elastic reaction force of the damping system during the operation of the damping system may be adapted to changing requirements.

[0017] The reservoir piston preferably includes a reservoir piston rod extending into the damping chamber of the fluid reservoir. For example, the reservoir piston may be formed as a disc and have the reservoir piston rod attached to the center of the disc. The reservoir piston rod is a convenient way to achieve a reservoir piston having a damping chamber surface area that is smaller than a reaction chamber surface area. Furthermore, the reservoir piston rod may be sealed in a reliable manner to the lateral reservoir wall of the fluid reservoir using a conventional shaft seal, to fluid-tightly separate the damping chamber from the reaction chamber.

[0018] The damping chamber of the fluid reservoir preferably has a smaller diameter than the reaction chamber of the fluid reservoir, in particular perpendicular to the longitudinal axis of the fluid reservoir. Due to pressure transmission by the reservoir piston, the pressure inside the damping chamber is higher than that inside the reaction chamber. Reducing the diameter of the damping chamber reduces the force acting on the lateral reservoir wall of the fluid reservoir that delimits the damping chamber, which in particular leads to increased mechanical stability of the fluid reservoir without requiring an increase in the thickness of the lateral reservoir wall.

[0019] The lateral reservoir wall of the fluid reservoir, which delimits the damping chamber and the reaction chamber of the fluid reservoir, preferably has the same wall thickness in the damping chamber and the reaction chamber, and / or is preferably integrally formed and preferably made of aluminum. These embodiments of the fluid reservoir are very lightweight and can be produced very easily, for example by impact extrusion. For example, the lateral reservoir wall may surround the longitudinal axis of the fluid reservoir, and / or the lateral reservoir wall may be formed at least in sections as a cylindrical shape.

[0020] The fluid reservoir preferably includes a control mechanism for adjusting the volume of the reaction chamber. For example, this control mechanism may include a screw extending through the wall of the fluid reservoir into the reaction chamber. Increasing the volume of the reaction chamber may decrease the pressure of the reaction fluid, and vice versa. By adjusting the pressure of the reaction fluid, the elastic reaction force of the damping system during the operation of the damping system may be adapted to changing requirements. In particular, the volume of the reaction chamber may be adjusted to compensate for pressure fluctuations of the reaction fluid due to temperature fluctuations of the reaction fluid.

[0021] The adjustment means is preferably designed to automatically increase the volume of the reaction chamber in accordance with the temperature rise of the reaction fluid in order to automatically compensate for pressure fluctuations of the reaction fluid due to temperature fluctuations of the reaction fluid. For this purpose, the adjustment means may include a compensation medium and a compensation piston, such as those described in the documents DE3141295A1 (Patent Document 4), EP1795777A2 (Patent Document 5), WO2021 / 233842A1 (Patent Document 6), or EP3967898A1 (Patent Document 7).

[0022] The lateral reservoir walls of the fluid reservoir preferably include a low-friction surface layer, such as a surface coating, surface structure, and / or electrolytic oxidation layer, to reduce friction between the lateral reservoir walls of the fluid reservoir and the reservoir piston. For example, the lateral reservoir walls may surround the longitudinal axis of the fluid reservoir, and / or the lateral reservoir walls may be formed in a cylindrical shape in at least one area.

[0023] At least one fluid damper preferably includes a damper piston, which divides the damping volume of at least one fluid damper into a rear chamber and a front chamber. The division is preferably designed to be fluid-sealed.

[0024] The damping chamber of the fluid reservoir is preferably connected to the front chamber to allow fluid to flow through. The damper piston is preferably movable in the insertion direction, increasing the volume of the rear chamber and decreasing the volume of the front chamber. The damper piston is preferably movable in the withdrawal direction, decreasing the volume of the rear chamber and increasing the volume of the front chamber.

[0025] The insertion and removal directions are preferably oriented in opposite directions along the linear longitudinal axis of at least one fluid damper, and the damper piston is capable of moving linearly along this longitudinal axis. In an alternative embodiment, the damper piston is capable of movement by rotation around a rotation axis or by elastic deformation of the damper piston.

[0026] The damper piston rod is preferably attached to the damper piston and guided from at least one damper through the rear chamber of the damping volume. The damper piston rod is preferably guided along the linear longitudinal axis of at least one damper.

[0027] When a damping system is used to dampen the motion of a first component and a second component relative to each other, a damper piston, in particular a damper piston rod, may be attached to the first component, and the damper wall of at least one damper partitioning the damping volume may be attached to the second component.

[0028] When the damper piston is moved from its stationary position to the insertion direction, the fluid is pushed by the damper piston and / or damper piston rod from the front chamber of the damping volume of at least one damper to the rear chamber of the damping volume and / or the damping chamber of the fluid reservoir. As a result, the damping fluid pushes the reservoir piston in the compression direction, compressing the reaction fluid in the reaction chamber of the fluid reservoir. The pressure of the compressed reaction fluid pushes the reservoir piston back in the expansion direction, thereby pushing the damping fluid back into the damping volume of at least one damper.

[0029] In this way, the piston's motion in the insertion direction from a stationary position is reversed into a withdrawal direction by a reaction fluid in a fluid reservoir that functions like a gas spring. Similarly, the piston's motion in the withdrawal direction from a stationary position is reversed into an insertion direction by a reaction fluid in a fluid reservoir.

[0030] The flow resistance of the damping fluid, which flows from the front chamber to the rear chamber and / or the damping chamber, and in the reverse direction, dampens the motion of the damper piston in the insertion and withdrawal directions.

[0031] At least one fluid damper preferably includes at least one overflow channel connecting the rear chamber to the front chamber for fluid conduction, and this at least one overflow channel is preferably located in the lateral damper wall of the damper piston and / or damping volume. The overflow channel may form at least part of a fluid conduit connecting the damping volume of at least one fluid damper to the damping chamber of the fluid reservoir for fluid conduction.

[0032] The overflow channel allows the damping fluid to flow in a controlled manner from the front chamber to the rear chamber, and vice versa. Therefore, leakage of the damping fluid between the damper piston and the damper wall surrounding the damping volume does not affect the behavior of the damping system. Consequently, the damper piston may be designed without a seal, which makes the damping system particularly easy and inexpensive to manufacture.

[0033] In embodiments having an overflow channel, the amount of damping fluid displaced by the motion of the damper piston and the attached damper piston rod is defined by the volume of the damper piston rod inserted into the damping volume. Therefore, the damping force and reaction force of at least one damper can be easily adapted by replacing the damper piston rod with a damper piston rod having a different diameter.

[0034] At least one fluid damper preferably includes a first overflow channel that allows damping fluid to flow only from the rear chamber to the front chamber, and a second overflow channel that allows damping fluid to flow only from the front chamber to the rear chamber, wherein the first overflow channel preferably has a different flow resistance to the damping fluid than the second overflow channel.

[0035] Two overflow channels with different flow resistances allow for the definition of different damping forces for the insertion and withdrawal directions of the damper piston. In this way, the damping characteristics of the damping system can be adapted to various applications.

[0036] In embodiments of the present invention, the damping chamber of the fluid reservoir is connected to the rear and front chambers of at least one fluid damper to conduct fluid. In this way, the damper piston of at least one fluid damper can function as a double-acting piston, which particularly enables the design of a compact fluid damper.

[0037] The damping system preferably includes at least one overflow valve for regulating the flow of damping fluid between the rear chamber and the front chamber of at least one fluid damper. The overflow valve is preferably located in an overflow channel that connects the rear chamber to the front chamber to allow fluid conduction. The overflow valve allows for adjustment of the flow resistance to the damping fluid, thereby regulating the damping force of the damping system.

[0038] The damping system preferably includes, for example, two or more overflow valves for defining two or more damping forces of the damping system depending on the direction of motion and / or velocity of motion of the damper piston of at least one damper.

[0039] Preferably, at least one overflow valve is adjustable during the operation of the damping system to accommodate the need to change one or more damping forces of the damping system.

[0040] The damping system preferably includes at least a first fluid damper and a second fluid damper, the damping volumes of the first and second fluid dampers being connected to the damping chamber of the fluid reservoir to allow fluid to flow through. By connecting two or more fluid dampers to a single fluid reservoir, the damping system becomes particularly compact and lightweight. Furthermore, the damping behavior of two or more fluid dampers can be synchronized in a simple manner by connecting them to the same fluid reservoir.

[0041] The damping system is preferably configured to dampen the motion of a component that is displaceable from a stationary position in a first direction and a second direction, wherein a first fluid damper is configured to dampen the motion of the component when it is displaced from a stationary position in the first direction, and a second fluid damper is configured to dampen the motion of the component when it is displaced from a stationary position in the second direction.

[0042] Preferably, only one of the first and second fluid dampers dampens the motion of the component at any position away from its stationary position. When only one of the two fluid dampers is operating at any position of the component away from its stationary position, the two dampers can share the same fluid reservoir particularly efficiently.

[0043] The damper piston rod of the first fluid damper is preferably guided through a first hole in the first flange of the component, and the piston rod of the second fluid damper is preferably guided through a second hole in the second flange of the component. Each damper piston rod preferably includes a stopper, which prevents the piston rod from passing through its respective hole when the stopper is in contact with its respective flange. This embodiment can be made to cause, in a particularly simple manner, for only one of the first and second fluid dampers to dampen the motion of the component at any position away from its stationary position.

[0044] For example, when the above components are moved from a stationary position in a first direction, the stopper of the first fluid damper may abut against its respective flange, causing the damper piston rod of the first lateral damper to be inserted into the first fluid damper and providing a damping effect. The damper piston rod of the second fluid damper may slide freely through the holes in its respective flange without the damper piston rod of the second fluid damper being inserted into the second fluid damper.

[0045] The first fluid damper and / or the second fluid damper are preferably pressurized, for example, by the pressure of the reaction fluid in the reaction chamber of the fluid reservoir, in order to force the components to be in a resting position. In this way, the components are reliably returned to the resting position after each movement, thereby avoiding any problems that may occur if the components remain in an undefined position outside of the resting position.

[0049] The reservoir piston 122, including the reservoir piston rod 132, is movable in a compression direction CD, which increases the volume of the damping chamber 123 and decreases the volume of the reaction chamber 124. Furthermore, the reservoir piston 122 is movable in an expansion direction DD, which decreases the volume of the damping chamber 123 and increases the volume of the reaction chamber 124. For example, the compression direction CD and the expansion direction are oriented in opposite directions along the longitudinal axis RA of the fluid reservoir 120.

[0053] Preferably, the damping chamber 123 of the fluid reservoir 120 has a smaller diameter than the reaction chamber 124 of the fluid reservoir 120, and is perpendicular to the longitudinal axis RA of the fluid reservoir 120.

[0054] The lateral reservoir wall 131 of the fluid reservoir 120, which separates the damping chamber 123 and the reaction chamber 124 of the fluid reservoir 120, for example, the cylindrical wall surrounding the longitudinal axis RA of the fluid reservoir 120, may have a wall thickness in the damping chamber 123 that is greater than the wall thickness in the reaction chamber 124.

[0057] Each of the fluid dampers 110a and 110b includes damper piston rods 115a and 115b, each attached to a damper piston (not shown) and guided from the fluid dampers 110a and 110b. Each of the fluid dampers 110a and 110b includes damper fixing means 109a and 109b for fixing the fluid dampers 110a and 110b to a first component (not shown). Each of the damper piston rods 115a and 115b includes rod fixing means 108a and 108b for fixing the damper piston rods 115a and 115b to a second component (not shown). In this way, the fluid dampers 110a and 110b can dampen the motion of the first component relative to the second component.

[0059] The damping system 100 shown in Figure 3 differs from that shown in Figure 2 in that each of the damper piston rods 115a, 115b includes stoppers 119a, 119b instead of rod fixing means 108a, 108b. The stoppers 119a, 119b are designed to prevent each piston rod 115a, 115b from passing through holes in the flanges of the second component when the stoppers 119a, 119b are in contact with their respective flanges.
