Definitions
- the invention relates to an elastic element for a vehicle, in particular for a running gear of a rail vehicle, with a housing and with at least one first buffer elastically connected to the housing and at least one first fluid chamber and one second fluid chamber, which are encased by the housing.
- Elastic elements such as springs and dampers made of different materials (e.g. metal, elastomer, etc.), stops, hydraulic bushings, etc. are used at various points in a vehicle or chassis.
- engines or drive units are coupled via special engine or drive bearings with elastic elements on motor vehicle bodies, undercarriage frames of rail vehicles or wheel set bearing housings of rail vehicles.
- elastic elements e.g. hydraulic bushes
- wheel set guide devices between wheel sets and the chassis frame of rail vehicles.
- Drive bearings, wheelset guide devices, etc. must be designed and dimensioned according to the expected dynamic reactions and arranged on the running gear. A carefully designed suspension and damping capacity is particularly important. Furthermore, when arranging and dimensioning drive bearings, in particular in the case of internally mounted undercarriages of rail vehicles and in particular in the case of drives coaxial with wheelset shafts, very limited installation space budgets must often be taken into account.
- Fastening modules can be provided between the drive motor and the chassis frame, which enable the drive motors to be replaced quickly.
- the WO 2019/185119 A1 known, in which a chassis of a rail vehicle is shown, the drive unit is mounted on two wheel set bearing housings of a wheelset via four spring devices. For every two spring devices, a damper device is connected in parallel, which is designed as a hydraulic bearing with two stop buffers. Accordingly, two damping devices are arranged between the drive unit and the wheelset bearings.
- the WO 2017/157740 A1 a chassis for a rail vehicle with active wheelset control, in which an actuator and, connected in parallel with the actuator, an elastic bearing with frequency- and amplitude-dependent stiffness are arranged between a chassis frame and a wheelset.
- the US 3,240,355A a hydraulic shock absorber unit for rail vehicles.
- the shock absorber unit comprises a cylinder and a hydraulic ram guided telescopically therein.
- a piston head connected to the hydraulic ram encases a bolt arranged in a cylinder interior and connected to the cylinder.
- Compensating channels are arranged in the piston head, via which a hydraulic fluid can flow from the cylinder interior into a first tappet interior as a function of a hydraulic pressure.
- a valve, via which a second interior space of the ram can be supplied with a gas, is arranged on a cover designed in one piece with the hydraulic ram.
- the invention is therefore based on the object of providing an elastic element which has been developed further compared to the prior art and which enables a large spectrum of frequency-dependent damping and rigidity properties.
- the housing comprises at least a first housing part and a second housing part, which are connected to one another, with the at least first housing part and the second housing part having at least one plate with at least one fluid channel, which penetrating the at least one plate and connecting the at least first fluid chamber to the second fluid chamber, is interposed and detachably connected to the housing, and wherein the at least first buffer is disposed adjacent to the at least first fluid chamber, the housing having a first vehicle or .Chassis component connectable and at least the first buffer is oriented so that it can be brought into contact with a second vehicle or chassis component. This achieves a modular construction of the elastic element.
- the fluid channel is designed according to the necessary damping and rigidity properties. Because the plate is detachably connected to the housing, it is possible to exchange it, ie to replace it with a different plate with a different fluid channel or with a plurality of fluid channels. Furthermore, this has the effect that not just one but a plurality of plates can be provided between the first housing part and the second housing part.
- the elastic element can be used as a bearing or coupling device (e.g. as an engine, transmission or drive bearing or as a wheel set guide or
- Wheel set control device are used.
- both upward and downward movement or both forward and backward movement of a first vehicle component, e.g., a first chassis component, relative to a second vehicle component, e.g., a second chassis component, can be sprung or dampened.
- the at least first buffer is encased by an elastic first ring and the first ring is encased by the at least first housing part, the at least first buffer being arranged protruding from the at least first housing part.
- An elastic connection between the first buffer and the first housing part allows power to be transmitted between the first buffer and the first fluid chamber, and the springing and damping properties of the elastic element are improved. Due to the elastic first ring, the first buffer moves back towards its starting position when the load is relieved.
- the at least one plate has at least one first hole between a plate base area and a plate cover area.
- This measure sets a damping and rigidity characteristic of the elastic element.
- a single hole or a plurality of holes can be provided in the plate, depending on which damping and rigidity properties are required.
- the at least one plate has a first hole, a second hole, a third hole, a fourth hole and a fifth hole, with the first hole, the second hole, the third hole and the fourth hole are provided at corners of an imaginary rectangle and the fifth hole is provided in the center of the rectangle.
- This measure achieves a rather soft stiffness characteristic of the elastic element according to the invention.
- a favorable solution is achieved when the at least one plate is designed as a spiral channel plate.
- the spiral channel plate is a plate with an elongated spiral recess. This measure achieves a long line length of the fluid channel.
- At least one first spiral channel plate adjoining the at least one plate is arranged between the at least first housing part and the second housing part and is detachably connected to the housing, with the at least first bore of the at least one plate connecting to one end of a spiral-shaped first Recess of the at least first spiral channel plate is arranged to cover.
- This measure improves frequency-dependent damping and rigidity properties of the elastic element.
- the elastic element has a low rigidity, with increasing frequency the elastic element becomes harder.
- a variable component behavior is achieved, which depends on the frequency of a load.
- This can be advantageous, for example, when the elastic element is used in a wheel set guide device of a running gear of a rail vehicle.
- a low level of rigidity of the wheelset guidance device is favorable, at high speeds, e.g. on a straight line, a high level of rigidity.
- the use of the elastic element according to the invention in wheel set guide devices consequently causes reduced wheel and rail wear when driving around curves and high running stability at high speeds.
- At least the first buffer has a first end face designed as a sliding surface.
- This measure reduces wear on the first buffer when it comes into contact with another component and relative movements (for example transverse movements) are carried out between the first buffer and this other component.

Description
Die Erfindung betrifft ein Elastikelement für ein Fahrzeug, insbesondere für ein Fahrwerk eines Schienenfahrzeugs, mit einem Gehäuse und mit zumindest einem mit dem Gehäuse elastisch verbundenen ersten Puffer sowie zumindest einer ersten Fluidkammer und einer zweiten Fluidkammer, welche von dem Gehäuse ummantelt sind.The invention relates to an elastic element for a vehicle, in particular for a running gear of a rail vehicle, with a housing and with at least one first buffer elastically connected to the housing and at least one first fluid chamber and one second fluid chamber, which are encased by the housing.
Eine mechanisch entkoppelte Lagerung von Fahrzeug- oder Fahrwerkskomponenten ist sowohl aus Komfort- als auch aus Sicherheitsgründen wichtig. Elastikelemente wie Federn und Dämpfer aus unterschiedlichen Materialien (z.B. Metall, Elastomer etc.), Anschläge, Hydrobuchsen etc. werden an verschiedenen Stellen in einem Fahrzeug oder in einem Fahrwerk eingesetzt. Beispielsweise werden Motoren oder Antriebseinheiten über spezielle Motor- oder Antriebslager mit Elastikelementen an Karosserien von Kraftfahrzeugen, Fahrwerksrahmen von Schienenfahrzeugen oder Radsatzlagergehäuse von Schienenfahrzeugen gekoppelt. Weiterhin werden Elastikelemente (z.B. Hydrobuchsen) beispielsweise als Radsatzführungseinrichtungen zwischen Radsätzen und Fahrwerksrahmen von Schienenfahrzeugen eingesetzt.A mechanically decoupled mounting of vehicle or chassis components is important for both comfort and safety reasons. Elastic elements such as springs and dampers made of different materials (e.g. metal, elastomer, etc.), stops, hydraulic bushings, etc. are used at various points in a vehicle or chassis. For example, engines or drive units are coupled via special engine or drive bearings with elastic elements on motor vehicle bodies, undercarriage frames of rail vehicles or wheel set bearing housings of rail vehicles. Furthermore, elastic elements (e.g. hydraulic bushes) are used, for example, as wheel set guide devices between wheel sets and the chassis frame of rail vehicles.
Bei Fahrwerken von Schienenfahrzeugen ist insbesondere im Bereich höherer Fahrgeschwindigkeiten zu beachten, dass dynamische Reaktionen, welche beispielsweise aufgrund von Gleislagefehlern von einem Gleis auf Fahrwerkskomponenten übertragen werden, mit zunehmender Fahrgeschwindigkeit an Intensität gewinnen.In the case of undercarriages of rail vehicles, it should be noted, particularly in the area of higher travel speeds, that dynamic reactions, which are transmitted from a track to undercarriage components, for example due to track geometry errors, increase in intensity with increasing travel speed.
Antriebslager, Radsatzführungseinrichtungen etc. müssen entsprechend den zu erwartenden dynamischen Reaktionen ausgebildet bzw. dimensioniert und auf den Fahrwerken angeordnet sein. Dabei ist insbesondere ein sorgfältig ausgelegtes Federungs- und Dämpfungsvermögen wichtig. Weiterhin müssen bei einer Anordnung und Dimensionierung von Antriebslagern insbesondere bei innengelagerten Fahrwerken von Schienenfahrzeugen und insbesondere bei zu Radsatzwellen koaxialen Antrieben häufig stark eingeschränkte Bauraumbudgets berücksichtigt werden.Drive bearings, wheelset guide devices, etc. must be designed and dimensioned according to the expected dynamic reactions and arranged on the running gear. A carefully designed suspension and damping capacity is particularly important. Furthermore, when arranging and dimensioning drive bearings, in particular in the case of internally mounted undercarriages of rail vehicles and in particular in the case of drives coaxial with wheelset shafts, very limited installation space budgets must often be taken into account.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber dem Stand der Technik weiterentwickeltes Elastikelement bereitzustellen, welches ein großes Spektrum an frequenzabhängigen Dämpfungs- und Steifigkeitseigenschaften ermöglicht.The invention is therefore based on the object of providing an elastic element which has been developed further compared to the prior art and which enables a large spectrum of frequency-dependent damping and rigidity properties.
Erfindungsgemäß wird diese Aufgabe gelöst mit einem Elastikelement der eingangs genannten Art, bei dem das Gehäuse zumindest ein erstes Gehäuseteil und ein zweites Gehäuseteil umfasst, welche miteinander verbunden sind, wobei dem zumindest ersten Gehäuseteil und dem zweiten Gehäuseteil zumindest eine Platte mit zumindest einem Fluidkanal, welcher die zumindest eine Platte durchdringend und die zumindest erste Fluidkammer mit der zweiten Fluidkammer verbindend vorgesehen ist, zwischengeordnet sowie mit dem Gehäuse lösbar verbunden ist und wobei der zumindest erste Puffer an die zumindest erste Fluidkammer angrenzend angeordnet ist, wobei das Gehäuse mit einer ersten Fahrzeug- bzw. Fahrwerkskomponente verbindbar ist und zumindest der erste Puffer mit einer zweiten Fahrzeug- bzw. Fahrwerkskomponente in Kontakt bringbar ausgerichtet ist. Dadurch wird ein modularer Aufbau des Elastikelements erzielt. Der Fluidkanal ist entsprechend erforderlicher Dämpfungs- und Steifigkeitseigenschaften ausgebildet. Aufgrund einer lösbaren Verbindung der Platte mit dem Gehäuse ist es möglich, diese zu tauschen, d.h. diese gegen eine andere Platte mit einem anderen Fluidkanal oder mit einer Mehrzahl an Fluidkanälen zu ersetzen. Weiterhin wird dadurch bewirkt, dass nicht nur eine, sondern eine Mehrzahl an Platten zwischen dem ersten Gehäuseteil und dem zweiten Gehäuseteil vorgesehen sein können.According to the invention, this object is achieved with an elastic element of the type mentioned at the outset, in which the housing comprises at least a first housing part and a second housing part, which are connected to one another, with the at least first housing part and the second housing part having at least one plate with at least one fluid channel, which penetrating the at least one plate and connecting the at least first fluid chamber to the second fluid chamber, is interposed and detachably connected to the housing, and wherein the at least first buffer is disposed adjacent to the at least first fluid chamber, the housing having a first vehicle or .Chassis component connectable and at least the first buffer is oriented so that it can be brought into contact with a second vehicle or chassis component. This achieves a modular construction of the elastic element. The fluid channel is designed according to the necessary damping and rigidity properties. Because the plate is detachably connected to the housing, it is possible to exchange it, ie to replace it with a different plate with a different fluid channel or with a plurality of fluid channels. Furthermore, this has the effect that not just one but a plurality of plates can be provided between the first housing part and the second housing part.
Hierdurch wird eine hohe Flexibilität bei einer Einstellung von Dämpfungs- und Steifigkeitscharakteristiken erzielt. Es ist ein großes Spektrum an Dämpfungs- und Steifigkeitseigenschaften realisierbar.This achieves a high level of flexibility when adjusting damping and rigidity characteristics. A large spectrum of damping and rigidity properties can be realized.
Ferner kann dadurch das Elastikelement als Lager- oder Koppelvorrichtung (z.B. als Motor-, Getriebe- oder Antriebslager oder als Radsatzführungs- bzw.Furthermore, the elastic element can be used as a bearing or coupling device (e.g. as an engine, transmission or drive bearing or as a wheel set guide or
Radsatzsteuereinrichtung) eingesetzt werden.Wheel set control device) are used.
Günstig ist es, wenn mit dem Gehäuse ein zweiter Puffer elastisch verbunden ist.It is favorable if a second buffer is elastically connected to the housing.
Durch diese Maßnahme wird eine Wirksamkeit des Elastikelements in zwei Richtungen ermöglicht. Beispielsweise können sowohl Auf-, als auch Abwärtsbewegungen oder sowohl Vorwärts-, als auch Rückwärtsbewegungen einer ersten Fahrzeugkomponente, z.B. einer ersten Fahrwerkskomponente, relativ zu einer zweiten Fahrzeugkomponente, z.B. einer zweiten Fahrwerkskomponente, gefedert oder gedämpft werden.This measure enables the elastic element to be effective in two directions. For example, both upward and downward movement or both forward and backward movement of a first vehicle component, e.g., a first chassis component, relative to a second vehicle component, e.g., a second chassis component, can be sprung or dampened.
Eine vorteilhafte Lösung erhält man, wenn der zumindest erste Puffer von einem elastischen ersten Ring ummantelt ist und der erste Ring von dem zumindest ersten Gehäuseteil ummantelt ist, wobei der zumindest erste Puffer aus dem zumindest ersten Gehäuseteil herausragend angeordnet ist.An advantageous solution is obtained if the at least first buffer is encased by an elastic first ring and the first ring is encased by the at least first housing part, the at least first buffer being arranged protruding from the at least first housing part.
Durch eine elastische Verbindung zwischen dem ersten Puffer und dem ersten Gehäuseteil wird eine Kraftübertragung zwischen dem ersten Puffer und der ersten Fluidkammer ermöglicht und es werden die Federungs- und Dämpfungseigenschaften des Elastikelements verbessert. Aufgrund des elastischen ersten Rings bewegt sich der erste Puffer bei Entlastung wieder in Richtung seiner Ausgangslage zurück.An elastic connection between the first buffer and the first housing part allows power to be transmitted between the first buffer and the first fluid chamber, and the springing and damping properties of the elastic element are improved. Due to the elastic first ring, the first buffer moves back towards its starting position when the load is relieved.
Es ist weiterhin hilfreich, wenn die zumindest eine Platte zumindest eine erste Bohrung zwischen einer Plattengrundfläche und einer Plattendeckfläche aufweist.It is also helpful if the at least one plate has at least one first hole between a plate base area and a plate cover area.
Durch diese Maßnahme wird eine Dämpfungs- und Steifigkeitscharakteristik des Elastikelements eingestellt. Es können eine einzige Bohrung oder aber auch eine Mehrzahl von Bohrungen in der Platte vorgesehen sein, je nachdem, welche Dämpfungs- und Steifigkeitseigenschaften erforderlich sind.This measure sets a damping and rigidity characteristic of the elastic element. A single hole or a plurality of holes can be provided in the plate, depending on which damping and rigidity properties are required.
In diesem Zusammenhang kann es vorteilhaft sein, wenn die zumindest eine Platte eine erste Bohrung, eine zweite Bohrung, eine dritte Bohrung, eine vierte Bohrung sowie eine fünfte Bohrung aufweist, wobei die erste Bohrung, die zweite Bohrung, die dritte Bohrung und die vierte Bohrung an Ecken eines gedachten Rechtecks vorgesehen sind und die fünfte Bohrung mittig in dem Rechteck vorgesehen ist.In this context, it can be advantageous if the at least one plate has a first hole, a second hole, a third hole, a fourth hole and a fifth hole, with the first hole, the second hole, the third hole and the fourth hole are provided at corners of an imaginary rectangle and the fifth hole is provided in the center of the rectangle.
Durch diese Maßnahme wird eine eher weiche Steifigkeitscharakteristik des erfindungsgemäßen Elastikelements erreicht.This measure achieves a rather soft stiffness characteristic of the elastic element according to the invention.
Eine günstige Lösung wird erzielt, wenn die zumindest eine Platte als Spiralkanalplatte ausgebildet ist.A favorable solution is achieved when the at least one plate is designed as a spiral channel plate.
Bei der Spiralkanalplatte handelt es sich um eine Platte mit einer langgezogenen, spiralförmigen Ausnehmung. Durch diese Maßnahme wird eine große Leitungslänge des Fluidkanals erzielt.The spiral channel plate is a plate with an elongated spiral recess. This measure achieves a long line length of the fluid channel.
Es ist weiterhin günstig, wenn dem zumindest ersten Gehäuseteil und dem zweiten Gehäuseteil zumindest eine, an die zumindest eine Platte angrenzende erste Spiralkanalplatte zwischengeordnet sowie mit dem Gehäuse lösbar verbunden ist, wobei die zumindest erste Bohrung der zumindest einen Platte sich mit einem Ende einer spiralförmigen ersten Ausnehmung der zumindest ersten Spiralkanalplatte deckend angeordnet ist.It is also favorable if at least one first spiral channel plate adjoining the at least one plate is arranged between the at least first housing part and the second housing part and is detachably connected to the housing, with the at least first bore of the at least one plate connecting to one end of a spiral-shaped first Recess of the at least first spiral channel plate is arranged to cover.
Durch diese Maßnahme werden frequenzabhängigen Dämpfungs- und Steifigkeitseigenschaften des Elastikelements verbessert.This measure improves frequency-dependent damping and rigidity properties of the elastic element.
Bei geringen Frequenzen weist das Elastikelement eine geringe Steifigkeit auf, mit zunehmender Frequenz wird das Elastikelement härter.At low frequencies, the elastic element has a low rigidity, with increasing frequency the elastic element becomes harder.
Es wird demnach ein variables Bauteilverhalten erzielt, welches von der Frequenz einer Belastung abhängig ist. Dies kann beispielsweise bei einem Einsatz des Elastikelements in einer Radsatzführungseinrichtung eines Fahrwerks eines Schienenfahrzeugs vorteilhaft sein. Hierbei ist bei geringen Geschwindigkeiten, insbesondere bei Bogenfahrten, eine geringe Steifigkeit der Radsatzführungseinrichtung günstig, bei hohen Geschwindigkeiten, z.B. auf einer Geraden, eine hohe Steifigkeit. Der Einsatz des erfindungsgemäßen Elastikelements in Radsatzführungseinrichtungen bewirkt folglich einen reduzierten Räder- und Schienenverschleiß bei Bogenfahrten und eine hohe Laufstabilitäten bei hohen Geschwindigkeiten.Accordingly, a variable component behavior is achieved, which depends on the frequency of a load. This can be advantageous, for example, when the elastic element is used in a wheel set guide device of a running gear of a rail vehicle. In this case, at low speeds, in particular when driving around curves, a low level of rigidity of the wheelset guidance device is favorable, at high speeds, e.g. on a straight line, a high level of rigidity. The use of the elastic element according to the invention in wheel set guide devices consequently causes reduced wheel and rail wear when driving around curves and high running stability at high speeds.
Eine vorteilhafte Ausgestaltung wird erreicht, wenn zumindest der erste Puffer eine als Gleitfläche ausgebildete erste Stirnfläche aufweist.An advantageous embodiment is achieved when at least the first buffer has a first end face designed as a sliding surface.
Durch diese Maßnahme wird ein Verschleiß des ersten Puffers reduziert, wenn dieser in Kontakt mit einem anderen Bauteil tritt und Relativbewegungen (z.B. Querbewegungen) zwischen dem ersten Puffer und diesem anderen Bauteil ausgeführt werden.This measure reduces wear on the first buffer when it comes into contact with another component and relative movements (for example transverse movements) are carried out between the first buffer and this other component.
