Description
Die Erfindung betrifft eine Vorrichtung zur Regelung von Bewegungen des Aufbaus von Kraftfahrzeugen gemäß dem Oberbegriff von Anspruch 1 und ein Federbein für Kraftfahrzeuge gemäß dem Oberbegriff von Anspruch 10.The The invention relates to a device for controlling movements the construction of motor vehicles according to the preamble of claim 1 and a strut for Motor vehicles according to the preamble of claim 10.
In diesem Zusammenhang stehen auch Systeme zur Änderung der Höhe des Aufbaus über der Fahrbahn. Hierzu ist es bekannt, bei Fahrzeugen mit Stahlfedern die Niveauregulierung im Regelfall in den Schwingungsdämpfer zu integrieren. Der Schwingungsdämpfer kann dabei auch automatisch und veranlaßt durch die vertikalen Fahrzeugbewegungen bis zur gewünschten Regelhöhe im Fahrzeugaufbau hoch gepumpt werden. Bei Fahrzeugen mit Luftfedern läßt sich die Regulierung der Höhe ebenfalls realisieren, indem die Luftfedern bei Belastung über entsprechende äußere Sensoren eine größere Druckmittelmenge erhalten. Weiterhin ist es auch bekannt bei Fahrzeugen mit einer hydropneumatischen Federung eine Regelung der Höhe mit Hilfe eines hydraulischen Stellgliedes zu realisieren. All diese bekannten Systeme dienen aber ausschließlich der Regelung der Höhenlage des Aufbaus also der Höhe des Fahrzeugaufbaus über dem Erdboden. Der Abstand des Aufbaus über der Fahrbahn ändert sich mit einer Änderung der Zuladung, so daß die genannten bekannten Systeme darauf ausgelegt sind, den entsprechenden Regelvorgang extrem langsam durchzufüh ren, wobei ein entsprechender Regelvorgang mehrere Sekunden bis zu Minuten andauern kann. Eine Ausregelung von dynamischen Lastschwankungen, beispielsweise als eine Einwirkung auf den gegenwärtigen Fahrzustand oder auf schnell ablaufenden Bewegungen des Aufbaus (beispielsweise sich aufschaukelnde Schwingungen) ist mit diesen bekannten Systemen unmöglich.In In this context, there are also systems for changing the height of the superstructure above the carriageway. For this purpose, it is known in vehicles with steel springs, the level control usually in the vibration damper to integrate. The vibration damper can also automatically and caused by the vertical vehicle movements to the desired rule height be pumped up in the vehicle body. For vehicles with air springs let yourself the regulation of height also realize by the air springs under load via corresponding external sensors a larger amount of pressure medium receive. Furthermore, it is also known in vehicles with a hydropneumatic suspension a regulation of altitude with the help of a hydraulic Actuator realize. All these known systems are used but exclusively the regulation of the altitude of the structure so the height of the Vehicle construction over the ground. The distance of the superstructure above the carriageway changes with a change the payload, so that the mentioned known systems are designed to the corresponding Control process extremely slowly durchzufüh ren, with a corresponding Control process can last several seconds to minutes. A Control of dynamic load fluctuations, for example as an effect on the present Driving condition or on fast running movements of the body (for example, oscillating vibrations) is with these known systems impossible.
Selbst wenn man aber die bekannten Systeme auf schnelle Regelvorgänge auslegen wollte, so stände der hierfür notwendige Energie – und Leistungsbedarf kaum zur Verfügung. Theoretisch ermöglichen voll aktive hydraulische Fahrwerksysteme zwar eine optimale Fahrwerksregelung hinsichtlich Fahrkomfort und Handling des Fahrzeugs. Sie erweisen sich jedoch unter Kostengesichtspunkten als unrealistisch und haben selbst dann, wenn zur Leistungseinsparung Zusatzbauteile vorgesehen sind, sehr hohe Leistungsanforderungen.Even but if you interpret the known systems to fast control operations wanted, so stand the one for this necessary energy - and Power requirement hardly available. Theoretically allow Although fully active hydraulic suspension systems provide optimum suspension control in terms of ride comfort and handling of the vehicle. They turn out However, from a cost point of view as unrealistic and have even if additional components are provided to save power are, very high performance requirements.

Aufgabe der Erfindung ist es eine einfach aufgebaute und wirksame Vorrichtung anzugeben, durch welche eine schnelle aktive Regelung der Bewegungen des Fahrzeugaufbaus für eine Erhöhung der Fahrzeugstabilität möglich ist. Aufgabe der Erfindung ist es weiterhin, ein Federbein anzugeben, welches für eine einfache und schnelle Regelung besonders geeignet ist. task The invention is a simply constructed and effective device specify, by which a fast active regulation of the movements of the vehicle bodywork for an increase in the vehicle stability possible is. The object of the invention is also to provide a strut, which for a simple and fast control is particularly suitable.
Die Aufgabe wird durch die sich aus dem Anspruch 1 ergebende Merkmalskombination gelöst.The The object is achieved by the combination of features resulting from claim 1 solved.
Durch die Erfindung wird auf einfache Weise eine dynamische aktive Fahrwerkregelung geschaffen, die ohne hydraulische Druckversorgung auskommt. Auf Basis der Erfindung kann zudem erreicht werden, daß der Energieverbrauch minimiert und der Komfort erhöht wird. Bei der erfindungsgemäßen Vorrichtung bildet ein elektromechanischer Antrieb ein aktives Feder-Dämpfer-System, welches als zusätzliche, im Fahrzeug unterzubringende Aggregate lediglich eine elektrische Energieversorgung und eine elektrische Ansteuerung benötigt. Der hydraulisch eigenständige Dämpfer kann erhalten bleiben.By The invention is easily a dynamic active suspension control created, which manages without hydraulic pressure supply. On Basis of the invention can also be achieved that the energy consumption minimized and increased comfort becomes. In the device according to the invention An electromechanical drive forms an active spring-damper system, which acts as an additional, In the vehicle to be housed units only an electric Power supply and electrical control needed. Of the hydraulically independent damper can be preserved.
Es ergibt sich ein besonders einfacher Aufbau für das Stellglied. Dabei ist ein vergleichsweise preiswerter Elektromotor in den Bereich des Aufbaus eingefügt, der sich über die erfindungsgemäße Vorrichtung an einer Radachse abstützt. Dieser Elektromotor treibt eine Gewindespindel an, auf deren Gewinde eine drehfest angeordnete und axial bewegbare Gewindeschraube sitzt. Dreht sich die Spindel so fährt die Schraube auf und ab und änderte damit die Höhenlage des Aufbaus. Der Motor und die von ihm angetriebene Spindel reagieren sehr schnell auf entsprechende Betätigungssignale, so dass die beschriebene Anordnung sehr gut zur dynamischen Regelung der Bewegungen des Fahrzeugaufbaus geeignet ist. Wenn das Fahrzeug jedoch ein Hydraulik-Aggregat besitzt, beispielsweise für eine Servo-Lenkung, so kann es sich unter Umständen empfehlen für den Antrieb des Stellgliedes einen hydraulischen Antrieb zu wählen.It This results in a particularly simple structure for the actuator. It is a comparatively inexpensive electric motor in the field of Structure inserted, which is about the device according to the invention supported on a wheel axle. This electric motor drives a threaded spindle, on the thread a rotatably mounted and axially movable threaded screw sits. Turns the spindle so drives the screw up and down and changed thus the altitude of the construction. The motor and the spindle driven by it react very quickly to appropriate actuation signals, so that the described arrangement very well for dynamic control of movements the vehicle body is suitable. However, if the vehicle is a hydraulic unit owns, for example a servo steering, so it may be recommended for the drive of the actuator to choose a hydraulic drive.
Um Energie bei der Bewegung des Aufbaus durch den Elektromotor zu sparen empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 2. Durch die Entlastungsfeder, die derart eingestellt ist, daß sie mit ihren nicht auf Block stehenden Windungen das Gewinde weitgehend frei von Auflagekräften durch den Aufbau des Fahrzeugs hält, wird es möglich, daß durch das Stellglied nur die dynamischen Bewegungen des Aufbaus ausgeregelt werden müssen. Das Gewinde bleibt dabei weitgehend von den Auflagekräften des Aufbaus verschont. Es ist allerdings notwendig, daß bei abwärts gerichteten Bewegungen des Aufbaus das Stellglied gegen die Kraft der Entlastungsfeder arbeiten muß. Dabei sollte die Feder derart eingestellt sein, daß in beiden Richtungen die von dem Motor auszuübende Kraft gleich groß ist.Around To save energy during the movement of the body by the electric motor recommended in a further development of the invention, the combination of features according to claim 2. By the relief spring, which adjusted is, that you with their non-block turns the thread largely free of supporting forces by holding the vehicle, will it be possible that by the actuator only the dynamic movements of the body are adjusted have to. The thread remains largely of the bearing forces of Spared construction. It is necessary, however, that in downwards Movements of the body the actuator against the force of the relief spring Must work. The spring should be set so that in both directions to be exercised by the engine Strength is the same.

Dazu muß jedes
der vier Stellglieder in der Lage sein, seine Fahrzeugecke anzuheben.
Die dazu notwendige Hubarbeit ist das Integral über (Verstellkraft × Verstellweg).
Entlastet man das Stellglied von der rein statischen Kraftkomponente,
so muß bei Regeleingriffen
nur ein Bruchteil der Energie aufgewandt werden. Daher wird, wie
in
Eine weitere Verbesserung läßt sich somit durch die Anwendung der Merkmale nach Anspruch 3 erreichen, wo die Verwendung von Gasfedern für die Tragfeder bzw. die Entlastungsfe der vorgeschlagen wird. Gasfedern bieten gegenüber Stahlfedern einen höheren Federungskomfort. Außerdem kann eine statische Einfederung, beispielsweise verursacht durch eine Gewichtserhöhung infolge von Zuladung, durch Zufuhr von Luft kompensiert werden. Der besondere Vorteil von Gasfedern besteht darin, daß die eigene Frequenz des Feder-Masse-Systems annähernd unabhängig von der Zuladung ist.A further improvement can be thus achieve by the application of the features according to claim 3, where the use of gas springs for the suspension spring or the relief of the is proposed. Gas springs offer greater suspension comfort than steel springs. Furthermore can cause a static deflection, for example caused by an increase in weight due to payload, be compensated by supplying air. The particular advantage of gas springs is that their own Frequency of the spring-mass system is approximately independent of the payload.
Weiterhin wird die Aufgabe durch die sich aus dem Anspruch 10 ergebende Merkmalskombination gelöst.Farther The object is achieved by the combination of features resulting from claim 10 solved.
Zum Regeln eines mit den erfindungsgemäßen Federbeinen ausgestatteten Fahrwerks ist mindestens die Sensorinformation über die Einfederwege notwendig. Dazu sind die erfindungsgemäßen Federbeine mit Wegsensoren ausgestattet. Weiterhin können auch Sensoren für die Aktuatorwege vorgesehen sein. Beide Sensorsysteme können im Federbein zu einer Sensoreinheit zusammengefasst sein. Außerdem können zur genauen Ermittlung des Systemzustands zusätzlich die pneumatischen Drücke in den Gasfedern sensiert werden. In vorteilhafter Weiterbildung der Erfindung empfiehlt sich daher die Anwendung der in den Ansprüchen 19 und 20 aufgeführten Merkmale.To the Rules of equipped with the invention struts Chassis, at least the sensor information on the compression travel is necessary. These are the struts invention equipped with displacement sensors. Furthermore, sensors for the actuator paths be provided. Both sensor systems can in the strut to a Be summarized sensor unit. Besides, for accurate determination of the system status in addition the pneumatic pressures be sensed in the gas springs. In an advantageous embodiment The invention therefore recommends the use of the in the claims. 19 and 20 listed Characteristics.
Das hier vorgestellte System vereint die Vorteile des technisch ausgereiften pneumatischen Systems zur aktiven Fahrwerk – Niveauregulierung und der in Wirkungsgrad, Bauform und Leistungsdichte optimierten elektromechanischen Aktuatoren zu einem vollaktiven Fahrwerkregelsystem mit minimalem Energiebedarf. Elektrische Energie wird nur in einem Bereich mittlerer Dynamik eingesetzt. Sehr schnelle Einfedervorgänge werden von dem konventionellen hydraulischen Dämpfer abge fangen, langsame Vorgänge von einem pneumatischen Niveauregulierungssystem. Der mittlere, von den elektromechanischen Aktuatoren abgedeckte Bereich betrifft vor allem das Ausregeln von Roll-, Nick- und Hubbewegungen des Fahrzeugs, wie sie bei Kurvenfahrt, beim Beschleunigen und Bremsen und beim Überfahren von Bodenwellen auftreten.The System presented here combines the advantages of the technically mature pneumatic system for active suspension - level control and the in efficiency, design and power density optimized electromechanical Actuators to a fully active suspension control system with minimal energy consumption. Electrical energy is only in a medium dynamic range used. Very fast bounce operations are from the conventional hydraulic damper catch, slow processes from a pneumatic level control system. The middle one, covered by the electromechanical actuators range especially the balancing of rolling, pitching and lifting movements of the vehicle, such as when cornering, when accelerating and braking and when driving over Bumps occur.
Bisherige Ansätze zur aktiven Fahrwerkregelung sind regelmäßig an dem zu hohen Energieverbrauch gescheitert, da meist versucht wurde, einen zu großen Dynamikbereich mit energieverbrauchender Aktuatorik abzudecken. Das vorgeschlagene System dagegen überlässt den Bereich hoher Dynamik, bei dem jedes aktive System energetisch überfordert wäre, einem passiven Dämpfer und den Bereich niedriger Dynamik der Niveauregulierung, die, einmal eingestellt, keine weitere Energiezufuhr benötigt. Auch der Energiebedarf im Bereich mittlerer Dynamik, in dem aktiv geregelt wird, ist durch den Einsatz der (vorzugsweise pneumatisch nachstellbaren) Aktuator-Entlastungsfedern minimiert. Der von dynamisch passiven Gasfedersystemen bekannte optimale Federungskomfort bleibt auch bei aktiver Fahrwerkregelung in vollem Umfang erhalten.Previous approaches for the active suspension control are regularly due to the high energy consumption failed, because it was usually tried too large a dynamic range covered with energy consuming actuator technology. The proposed System on the other hand leaves the High dynamic range, where every active system is energetically overwhelmed would be, one passive damper and the range of lower dynamics of the level control, which, once set, no further energy supply needed. Also the energy requirement in the field of medium dynamics, in which is actively regulated, is through the use of (preferably pneumatically adjustable) actuator relief springs minimized. The best known of dynamically passive gas spring systems Suspension comfort remains in full even with active chassis control Scope received.
Zur Darstellung einer aktiven Fahrwerkregelung mit minimalem Energieverbrauch sind ausgehend von einem Fahrzeug mit pneumatisch niveauregulierbarem Fahrwerk lediglich die Federbeine gegen die hier vorgestellten zusätzlich elektrisch verstellbaren auszutauschen, Sensorik und Regelelektronik ist hinzuzufügen. Im Fahrzeugchassis sind keine weitere Aggregate unterzubringen. Das System kann somit auch nachträglich ohne größere Probleme in ein Fahrzeug eingefügt werden.to Representation of an active chassis control with minimal energy consumption are based on a vehicle with pneumatically level controllable Suspension only the struts against the presented here additionally electrically adjustable to replace, sensors and control electronics is added. in the Vehicle chassis are no further units to accommodate. The System can therefore also subsequently without major problems inserted in a vehicle become.

Bei der Darstellung einer Regelung der Vertikaldynamik unter Verwendung von Luftfedern besteht die Möglichkeit, die Höhen der Luftsäulen eines Luftfedersystems durch Zu- und Abfuhr von zusätzlicher Luft nicht nur quasistatisch im Sinne einer Niveauregulierung, sondern auch dynamisch zu regeln. Ein solches Vorgehen hat sich jedoch bisher nur als wenig praktikabel erwiesen, da die Schallgeschwindigkeit in Luft eine physikalische Grenze für die bei schnellen Regelvorgängen mit hoher Amplitude erforderliche Strömungsgeschwindigkeit in den pneumatischen Zuleitungen bildet. Um nicht in die Nähe dieser Grenze zu kommen müßten inakzeptabel große Zuleitungsquerschnitte gewählt werden.at the representation of a control of the vertical dynamics using of air springs there is the possibility the heights the air columns an air spring system by supply and removal of additional Air not only quasi-statically in the sense of a level control, but also to regulate dynamically. However, such a procedure has so far only proved to be less practical, since the speed of sound in air a physical limit for those with fast control operations high amplitude required flow velocity in the forms pneumatic supply lines. To not be near this Boundaries would have to be unacceptable size Conductor cross sections selected become.
