Abstract

The wheel suspension system includes a transverse control arm (7) which restricts the transverse movement of the leaf springs (5) holding the wheels. The control is swivel-mounted in a plane running perpendicular to the vehicle vertical axis and attached in this plane to the leaf spring (5) outside of the transverse force active line of same. The leaf spring is mounted elastically pliable in the bearings for swivel movements in the swivel plane about the vertical axis. By attaching the track control arm in the travel direction before or behind the leaf spring it is possible to under or over steer the wheels when driving round bends.

Description

Die Erfindung betrifft ein Radaufhängungssystem für ein Kraftfahrzeug mit einer Querblattfeder nach dem Oberbegriff des Patentanspruchs.The invention relates to a suspension system for a Motor vehicle with a cross leaf spring according to the preamble of the claim.

Ein solches Radaufhängungssystem ist aus DE 42 01 180 A1 be­ kannt. Der Querlenker führt bei dieser Ausführung Schwenkbe­ wegungen in einer parallel zur Fahrzeughochachse verlaufenden Querebene aus.Such a wheel suspension system is known from DE 42 01 180 A1 knows. The wishbone guides Schwenkbe in this version movements in a direction parallel to the vertical axis of the vehicle Transverse plane.

Hiervon ausgehend beschäftigt sich die Erfindung mit dem Pro­ blem, das Eigenlenkverhalten eines Fahrzeuges mit einem gat­ tungsgemäßen Radaufhängungssystem zu beeinflussen.Proceeding from this, the invention deals with the pro blem, the self-steering behavior of a vehicle with a gat to influence the appropriate suspension system.

Eine Lösung dieses Problems wird mit einer Ausgestaltung nach den kennzeichnenden Merkmalen des Patentanspruchs erreicht.A solution to this problem is provided with an embodiment achieved the characterizing features of the claim.

Die Erfindung beruht auf dem Gedanken, die bei Kurvenfahrt eines Fahrzeuges an den an der Blattfeder angelenkten Rädern auftretenden Seitenkräfte außerhalb der Kraftwirklinie der Blattfeder in einer senkrecht zur Fahrzeughochachse verlau­ fenden Fahrzeug-Ebene auf den an der Karosserie in dieser Ebene schwenkbar angelenkten Querlenker zu übertragen. Da­ durch wirkt in dieser Fahrzeugebene ein Drehmoment auf die Blattfeder, die diese in dieser Ebene geringfügig ver­ schwenkt. Für eine derartige Schwenkbewegung der Blattfeder sind die die Blattfeder an der Karosserie abstützenden Lager entsprechend elastisch nachgiebig gestaltet.The invention is based on the idea that when cornering of a vehicle on the wheels articulated on the leaf spring lateral forces occurring outside the force action line of the Leaf spring in a perpendicular to the vehicle vertical axis fenden vehicle level on the body in this  Level pivotally articulated wishbones. There torque acts on the vehicle in this plane Leaf spring, which ver in this level slightly pivots. For such a pivoting movement of the leaf spring are the bearings that support the leaf spring on the body designed accordingly resilient.

Durch eine Anlenkung des Querlenkers in Fahrtrichtung des Fahrzeuges vor oder hinter der Blattfeder läßt sich ein Un­ ter- oder Übersteuern der an der Blattfeder angelenkten Räder bei Kurvenfahrten erzielen. Erwünscht ist insbesondere ein Untersteuern, wozu der Querlenker in Fahrtrichtung vor der Blattfeder an der Karosserie anzulenken ist.By articulating the wishbone in the direction of travel Vehicle in front of or behind the leaf spring can be an Un oversteer or oversteer of the wheels articulated on the leaf spring achieve when cornering. One is particularly desirable Understeer, for which the wishbone in the direction of travel before Leaf spring is to be hinged to the body.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An embodiment is shown in the drawing.

Diese zeigt in schematischer Darstellung ein Radaufhängungs­ system in einer Ansicht von oben längs der Fahrzeughochachse.This shows a schematic representation of a wheel suspension system in a view from above along the vertical axis of the vehicle.

Die Räder 1 eines Fahrzeuges sind über je eine Achse 2 und Gelenkteile 3 mit einer quer zu der Karosserie eines Fahrzeu­ ges verlaufenden Blattfeder 5 angelenkt. Mit den Gelenkteilen 3 verbunden ist jeweils eine Spurstange 4.The wheels 1 of a vehicle are articulated via an axle 2 and joint parts 3 with a leaf spring 5 extending transversely to the body of a vehicle. A tie rod 4 is connected to the joint parts 3 .

Die Blattfeder 5 ist an der Karosserie über zwei Lager 6 ge­ lagert. Diese Lager 6 besitzen eine-elastisch wirkende Lager­ füllung, die Quer- und Schwenkbewegungen der Blattfeder 5 in einer durch diese Lager 6 führenden senkrecht zur Fahrzeug­ hochachse verlaufenden Fahrzeug-Ebene erlaubt.The leaf spring 5 is supported on the body via two bearings 6 ge. These bearings 6 have an elastically acting bearing filling, which allows transverse and pivoting movements of the leaf spring 5 in a leading through this bearing 6 perpendicular to the vehicle vertical axis vehicle plane.

Ein Querlenker 7 begrenzt die Querbewegung der Blattfeder 5. In Gelenken 8 und 9 ist der Querlenker 7 schwenkbar in der durch die Lager 6 führenden senkrecht zur Fahrzeughochachse verlaufenden Fahrzeug-Ebene gelagert.A transverse link 7 limits the transverse movement of the leaf spring 5 . In joints 8 and 9 , the control arm 7 is pivotally mounted in the vehicle plane running through the bearings 6 and running perpendicular to the vertical axis of the vehicle.

Bei der Einleitung von bei einer Kurvenfahrt an den Rädern auftretenden Seitenkräften über die Blattfeder 5 in den Quer­ lenker 7 wird von dem Querlenker 7 ein Drehmoment auf die Blattfeder 5 ausgeübt. Für eine Kurvenfahrt entsprechend dem Pfeil K erhält die Blattfeder 5 durch ein derartiges Drehmo­ ment die in der Zeichnung strichpunktiert eingetragene Lage. Durch diese Lage der Blattfeder 5 und die sich hieraus erge­ bende Verdrehung der Räder 1 in Richtung der dort in der Zeichnung angegebenen strichpunktierten Linie wird ein unter­ steuerndes Eigenlenkverhalten des Fahrzeuges erzeugt. Ein solches Verhalten verbessert die Fahreigenschaften eines Fahrzeuges und ist daher in vielen Fällen erwünscht.Upon initiation occurring when cornering at the wheels to lateral forces via the leaf spring 5 in the cross handlebar 7, a torque is exerted on the leaf spring 5 of the suspension arm. 7 For cornering according to the arrow K, the leaf spring 5 receives the position shown in broken lines in the drawing by such a torque. This position of the leaf spring 5 and the resultant rotation of the wheels 1 in the direction of the dash-dotted line shown there in the drawing produces a self-steering behavior of the vehicle. Such behavior improves the driving properties of a vehicle and is therefore desirable in many cases.

Durch eine Lageveränderung des Anlenkpunktes des Lagers 8 an der Karosserie des Fahrzeuges innerhalb der durch die Lager 6 verlaufenden senkrecht zur Fahrzeughochachse ausgerichteten Fahrebene läßt sich das Eigenlenkverhalten gezielt zwischen Unter- und Übersteuern eines Fahrzeuges variieren. Ein Über­ steuern ist beispielsweise dadurch erzielbar, daß der Anlenk­ punkt des Lagers 8 an der Karosserie in Fahrtrichtung des Fahrzeuges hinter die Blattfeder 5 gelegt wird.By changing the position of the articulation point of the bearing 8 on the body of the vehicle within the driving plane running through the bearings 6 perpendicular to the vertical axis of the vehicle, the self-steering behavior can be specifically varied between understeering and oversteering of a vehicle. An over control can be achieved, for example, that the pivot point of the bearing 8 is placed on the body in the direction of travel of the vehicle behind the leaf spring 5 .
