Abstract
Description
Die
Erfindung betrifft ein Kraftfahrzeug mit einer Radaufhängung für die angetriebenen
Hinterräder
sowie mit einem diesen zugeordneten Hinterachsgetriebe, welches
zusammen mit Radaufhängungselementen
an der Karosserie des Fahrzeugs gelagert ist. Zum technischen Umfeld
wird beispielshalber auf die
Stand der Technik für Kraftfahrzeuge mit angetriebenen Hinterrädern ist es, das Hinterachsgetriebe elastisch in einem sog. Hinterachsträger zu lagern und diesen wiederum elastisch bevorzugt mit großvolumigen Gummilagern an der Karosserie zu befestigen. Dadurch wird einerseits eine gewisse Längsfederung des Radmittelpunktes bei niederfrequenten Fahrbahnanregungen erreicht und es ist andererseits eine akustische Entkopplung der Karosserie (und damit der Fzg.-Insassen) gegenüber höherfrequenten Anregungen wie Abrollgeräuschen, Verzahnungsgeräuschen oder Drehungleichförmigkeiten insbesondere aus dem Hinterachsgetriebe gewährleistet.was standing of technology for It is motor vehicles with driven rear wheels, the rear axle gear to be stored elastically in a so-called rear axle beam and this in turn elastic preferred with large volume To attach rubber bearings to the body. This will, on the one hand a certain longitudinal suspension the center of the wheel is reached with low-frequency road excitation and on the other hand it is an acoustic decoupling of the body (and thus the vehicle occupant) to higher-frequency suggestions such as rolling noise, gearing noises or rotational irregularities guaranteed especially from the rear axle gear.
Wegen der elastischen Verbindung zwischen dem Hinterachsträger und der Karosseriestruktur müssen die beiden betroffenen Bauteile, jedes für sich, hinsichtlich Steifigkeit und Festigkeit auf die auftretenden Betriebslasten bis zur Maximallast dimensioniert werden. Das führt zu relativ großen erforderlichen Querschnitten und Blechstärken und bringt Kosten- und Gewichtsnachteile mit sich.Because of the elastic connection between the rear axle and the body structure the two affected components, each individually, with regard to rigidity and strength to the operating loads occurring up to the maximum load be dimensioned. Leading to relatively large ones required cross sections and sheet thicknesses and brings cost and Weight disadvantages with it.
Eine demgegenüber günstigere Hinterachs-Gestaltung an einem Kraftfahrzeug nach dem Oberbegriff des Anspruchs 1 aufzuzeigen, ist Aufgabe der vorliegenden Erfindung.A In contrast, favorable Rear axle design on a motor vehicle according to the generic term point of claim 1 is the object of the present invention.
Die Lösung dieser Aufgabe ist dadurch gekennzeichnet, dass das Hinterachsgetriebe unter Zwischenschaltung sog. aktiver Lager oder schwingungsselektiver Aufnahmeeinheiten, insbesondere Piezo-Aktuatoren, direkt an der Karosserie befestigt ist und seinerseits zumindest Teile der Radaufhängung trägt. Vorteilhafte Aus- und Weiterbildungen sind Inhalt der Unteransprüche.The solution this task is characterized in that the rear axle gear with the interposition of so-called active bearings or vibration selective Recording units, in particular piezo actuators, directly on the Body is attached and in turn carries at least parts of the wheel suspension. advantageous Training and further education are included in the subclaims.
Erfindungsgemäß ist eine direkte, praktisch feste Verbindung zwischen dem Hinterachsgetriebe, genauer dem Gehäuse des Hinterachsgetriebes, und der Karosserie vorgesehen, und dieses Gehäuse bzw. das Hinterachsgetriebe fungiert quasi als Hinterachsträger bzw. übernimmt einen Teil von dessen Funktion. Praktisch fest ist die vorgeschlagene direkte Verbindung zwischen dem Getriebe-Gehäuse und der Karosserie bzw. deren Unterboden jedoch nur insofern, als geeignete Maßnahmen zur Unterdrückung einer Schwingungsübertragung vom Getriebe-Gehäuse in die Karosserie vorgesehen sind. Letzteres ist mit sog. aktiven Lagern oder schwingungsselektiven Aufnahmeeinheiten möglich. Beispielsweise bzw. bevorzugt können hierfür sog. Piezo-Aktuatoren vorgesehen sein. Die weiterhin erforderliche akustische Entkopplung im höherfrequenten Bereich (ca. ab 20 Hz) übernehmen dann also nicht mehr die bisher üblichen und nunmehr ersatzlos entfallenen Hinterachsträger-Gummilager, sondern bevorzugt aktiv angesteuerte Piezo-Aktuatoren, die bevorzugt mit den Befestigungsschrauben oder Befestigungselementen für das Gehäuse des Hinterachsgetriebes an die Karosserie bzw. deren Unterboden verspannt werden. Durch eine entsprechende elektronische Regelung kann die Kontraktion und Ausdehnung der Piezo-Aktuatoren so gestaltet werden, dass Anregungen z.B. durch Abroll- oder Verzahnungsgeräusche von den Fahrzeug-Insassen ferngehalten werden. Entsprechendes gilt für andere Bauarten aktiver Lager oder schwingungsselektiver Aufnahmeeinheiten.According to the invention direct, practically fixed connection between the rear axle gearbox, more precisely the housing of the rear axle gear, and the body, and this Housing or the rear axle transmission acts as a rear axle carrier or takes over part of its function. The proposed one is practically solid direct connection between the gearbox housing and the body or their underbody, however, only insofar as suitable measures for oppression a vibration transmission from the gearbox housing are provided in the body. The latter is so-called active Storage or vibration-selective recording units possible. For example or preferred therefor So-called piezo actuators can be provided. The acoustic required Decoupling in the higher frequency Take over the range (approx. From 20 Hz) then no longer the usual ones and now without replacement rear axle support rubber bearings, but preferably active controlled piezo actuators, the preferred with the mounting screws or fasteners for the casing of the rear axle gearbox to the body or its underbody be tense. With an appropriate electronic control the contraction and expansion of the piezo actuators can be designed so that Suggestions e.g. by rolling or gearing noises from be kept away from the vehicle occupants. The same applies to others Types of active bearings or vibration-selective recording units.
Selbstverständlich können anstelle
von Piezo-Aktuatoren auch andere geeignete sog. schwingungsselektive
Aufnahmeeinheiten vorgesehen werden, die bezüglich der genannten im wesentlichen festen
Verbindung zwischen dem Hinterachsgetriebe und der Karosserie insbesondere
im höherfrequenten
Bereich als sog. Schwingungs-Isolatoren wirken können bzw. eine Übertragung
solcher höherfrequenten
Schwingungen (im Bereich > 20
Hz) im wesentlichen verhindern können.
In diesem Zusammenhang ist auf die eingangs zweitgenannte
In Abhängigkeit von den jeweils vorliegenden geometrischen Verhältnissen, bspw. von der Gestaltung des Gehäuses des Hinterachsgetriebes, und abhängig von den jeweiligen Anforderungen ist es möglich, dass auf einen eigenständigen Hinterachsträger vollständig verzichtet wird. Dann ist die Fzg.-Hinterachse bzw. sind deren radführende Lenker im wesentlichen am Hinterachsgetriebe bzw. an dessen Gehäuse aufgehängt. In der Regel dürften jedoch weitere Abstützungen zumindest einiger Radführungslenker bzw. allgemein sog. Radaufhängungselemente gegenüber der Karosserie erforderlich sein, wobei diese dann vorzugsweise über Feder-Dämpfer-Elemente und weitere schwingungsselektive Aufnahmeeinheiten an der Karosserie abgestützt sein können.In dependence of the prevailing geometrical relationships, for example of the design of the housing of the rear axle gear, and dependent Depending on the requirements, it is possible that an independent rear axle support is completely dispensed with becomes. Then the vehicle rear axle or are their wheel-guiding handlebars essentially hung on the rear axle gear or on its housing. In usually however further supports at least some wheel control handlebars or generally so-called wheel suspension elements across from the body may be necessary, these then preferably via spring damper elements and others vibration-selective receiving units to be supported on the body can.

Die
Hinterachse
Mit der vorliegenden Erfindung ergeben sich erhebliche Bauraum- und Gewichtsersparnisse; ferner kann ggf. vollständig auf einen eigenständigen Hinterachsträger verzichtet werden. Die einzelnen Komponenten Getriebe, Fahrwerk und Karosserie werden entkoppelt und es ergibt sich eine Verbesserung der Akustik, wobei darauf hingewiesen sei, dass durchaus eine Vielzahl von Details abweichend von obigen Erläuterungen gestaltet sein kann, ohne den Inhalt der Patentansprüche zu verlassen.With The present invention results in considerable space and Weight savings; furthermore, an independent rear axle support can be dispensed with entirely become. The individual components transmission, chassis and body are decouples and there is an improvement in acoustics, whereby it should be noted that quite a lot of details deviating from the above explanations can be designed without leaving the content of the claims.
