Abstract
Kraftfahrzeug-Vorderwagen, umfassend ein Tragwerk, ein Antriebsaggregat (6), das im Crashfall über Gleitflächen (18, 19, 20) nach unten ablenkbar ist, und einen steifen Hilfsrahmen (4), der als Träger einer Vormontageeinheit mit Radaufhängungen und Lenkung einschließlich Lenkgetriebe (5) des Fahrzeugs fest mit dem Tragwerk verbunden ist, dadurch gekennzeichnet, daß der Hilfsrahmen (4) an einem hinter dem Antriebsaggregat (6) liegenden Bereich mindestens eine schräg nach hinten unten weisende Gleitfläche (18) aufweist, und daß das Antriebsaggregat (6) eine jeweils korrespondierende Gegengleitfläche (19, 20) derart ausbildet, daß in einem normalen Betriebszustand zwischen den Gleitflächen (18, 19, 20) des Hilfsrahmens (4) und des Antriebsaggregats (6) ein Längsabstand (21) besteht und bei einem Crash nach einem Verschwinden des Längsabstandes (21) das hilfsrahmenseitige Ende des Antriebsaggregats (6) nach unten abgelenkt wird.Motor vehicle front end, comprising a supporting structure, a drive unit (6) which in the event of a crash has sliding surfaces (18, 19, 20) is deflectable downwards, and a rigid subframe (4), as a carrier a pre-assembly unit with wheel suspensions and steering including steering gear (5) of the vehicle is firmly connected to the structure, characterized in that that the subframe (4) at least behind a drive unit (6) an oblique having downwardly facing sliding surface (18), and that the drive unit (6) forms a corresponding counter sliding surface (19, 20) in such a way, that in a normal operating state between the sliding surfaces (18, 19, 20) of the subframe (4) and the drive unit (6) has a longitudinal spacing (21) and in a crash after a disappearance of the longitudinal distance (21) the auxiliary frame end of the drive unit (6) after is deflected down.
Description
Die
Erfindung betrifft einen Kraftfahrzeug-Vorderwagen gemäß dem Oberbegriff
des Patentanspruchs 1. Ein derartiger Kraftfahrzeug-Vorderwagen
ist aus der
Kraftfahrzeug-Vorderwagen
mit einer Hilfsrahmenkonstruktion sind allgemein bekannt. Eine solche
Konstruktion, wie sie beispielsweise auch in der
Im Crashfall kommt bei der Verkürzung des Vorderwagens ein Aggregatgehäuse, in der Regel ein Getriebe- oder Differentialgehäuse, in Kontakt mit dem starren Hilfsrahmen, wodurch eine Verzögerungsspitze entsteht, die für die Fahrzeuginsassen gefährlich werden kann. Außerdem wird der Hilfsrahmen nach hinten in Richtung des Fahrgastraums gedrückt, wodurch die Aufbaustruktur kollabieren kann.in the Crash case comes with the shortening of the front end of the car, usually a gearbox or differential case, in contact with the rigid Subframe, creating a deceleration tip arises for the vehicle occupants dangerous can be. Furthermore the subframe is pushed back towards the passenger compartment, whereby the body structure can collapse.
Zur
Vermeidung des Eindringens des Antriebsaggregats in die Fahrgastzelle
bei einem Crash sind verschiedene Konstruktionen bekannt, die im Prinzip
darauf hinauslaufen, beim Crash das Antriebsaggregat zumindest mit
einem spritzwandnahen, eine geringere Höhe als der Rest des Antriebsaggregats
besitzenden Bereich gleichsam unter das Fahrzeug zu führen, also "tauchen" zu lassen. Aus der

Gemeinsam ist diesen Konstruktionen eine störende Empfindlichkeit gegen Abweichungen der Richtung der beim Crash auftretenden Kräfte von der Längsrichtung.Together is these structures a disturbing sensitivity against Deviations in the direction of the forces occurring during the crash the longitudinal direction.
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Kraftfahrzeug-Vorderwagen unter Wahrung seiner Vorteile – Verwendung eines Hilfsrahmens zur Bildung einer Vormontageeinheit insbesondere für die Lenkeinrichtung – zu schaffen, der hinsichtlich seines Crashverhaltens optimiert ist.Of the Invention is based on the object, a generic motor vehicle front under Maintaining its benefits - Use a subframe for forming a pre-assembly in particular for the Steering device - too create, which is optimized in terms of its crash behavior.
Diese Aufgabe wird durch einen Kraftfahrzeug-Vorderwagen mit den Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den weiteren Patentansprüchen angegeben.These Task is by a motor vehicle front end with the features of claim 1. Advantageous embodiments The invention are specified in the further claims.
Ein wesentliches Merkmal der Erfindung ist eine solche Gestaltung des Hilfsrahmens, daß er sich gleichsam selber gegen eine kritische Kraftbeaufschlagung im Crashfalle durch das sich dann nach hinten verlagernde Antriebsaggregat schützt, wobei das Lenkgetriebe so angeordnet ist, daß es diese Schutzwirkung nicht nachteilig beeinflußt. Durch die Erfindung wird vermieden, daß durch Kraftbeaufschlagung des starren Hilfsrahmens eine gefährliche Verzögerungsspitze auftritt. Auch wird der Hilfsrahmen durch das Antriebsaggregat nicht nach hinten gedrückt, so daß dadurch sonst auftretende gefährliche Beeinflussungen der Struktur des Fahrzeugs ausgeschlossen sind.One An essential feature of the invention is such a design of the Subframe that he itself as it were against a critical application of force in the Crash trap through the then shifting rear drive unit protects wherein the steering gear is arranged so that it does not have this protective effect adversely affected. By the invention it is avoided that by applying force The rigid subframe is a dangerous deceleration tip occurs. Also, the subframe is not by the drive unit pushed to the back, so that otherwise dangerous Influencing the structure of the vehicle are excluded.
Ein weiterer Vorteil der erfindungsgemäßen Lösung ist darin zu sehen, daß infolge des Ablenkens des Antriebsaggregats durch die entsprechende Ausbildung des starren Hilfsrahmens in Richtung nach unten die Deformationslänge des Vorderwagens vergrößert wird gegenüber dem Fall, daß das Antriebsaggregat sich auf dem Hilfsrahmen gleichsam abstützt. Diese Vergrößerung des zur Verfügung stehenden Deformationswegs des Vorderwagens erfordert also keine konstruktive Verlängerung desselben.One Another advantage of the solution according to the invention is the fact that as a result the deflection of the drive unit by the appropriate training of the rigid subframe in the downward direction of the deformation length of Front carriage is enlarged across from the case that the drive unit is supported on the subframe as it were. This enlargement of the available deformation path of the front end thus requires no structural extension thereof.

Je breiter die Gleit- und Gegengleitflächen sind, desto besser ist die Einhaltung der angestrebten Wirkung bei einem schrägen Crash.ever wider the sliding and Gegengleitflächen are, the better compliance with the desired effect in an oblique crash.
Mit der Erfindung ist demgemäß mit einfachen Mitteln ein gattungsgemäßer Vorderwagen geschaffen, der hinsichtlich seines Crashverhaltens optimiert ist.With The invention is accordingly simple Means a generic front end created, which is optimized in terms of its crash behavior.
