Description
Die Erfindung bezieht sich auf Einstellvorrichtungen für mit Verdrängerkolben versehene Fahrwerk-Schwingungsdämpfer an Fahrzeugen unter Benutzung einer beim Befahren von Kurven mit Hilfe des Lenkrades verstellbaren Drossel. Derartige Vorrichtungen sind auf der Grundlage hydraulischer Schwingungsdämpfer bereits vorgeschlagen worden. Die Erfindung besteht hingegen im wesentlichen darin, daß der Dämpfer als hydropneumatischer Schwingungsdämpfer mit hydraulisch wirkendem Drosselorgan und der Verdrängerkolben als im hydraulischen Bereich des Schwingungsdämpfers arbeitender Dämpferkölben ausgebildet ist. Die Anordnung kann so getroffen sein, daß beim Drehen des Lenkrades nur die Schwingungsdämpfer der kurvenäußeren Räder im Sinne einer zusätzlichen Dämpfung der Hubbewegungen beeinflußt werden.The invention relates to adjusting devices for with displacement pistons provided chassis vibration damper on vehicles using one when driving on of curves with the help of the steering wheel adjustable throttle. Such devices have already been proposed on the basis of hydraulic vibration dampers. The invention, however, consists essentially in the fact that the damper as a hydropneumatic Vibration damper with a hydraulically acting throttle element and the displacement piston designed as a damper piston working in the hydraulic area of the vibration damper is. The arrangement can be made so that when turning the steering wheel only the Vibration dampers for the wheels on the outside of the curve in the sense of additional damping the stroke movements are influenced.
Solche Anordnungen haben den Vorteil, daß die Fahrwerkschwingungen beim Geradeausfahren weniger als beim Kurvenfahren gedämpft sind. Die stärkere Dämpfung, insbesondere auf der kurvenäußeren Seite, wirkt sich in einem besseren Spurhalten und einem geringeren Kurvenneigungswinkel des Wagenkastens aus. Ein weiterer Vorteil der erfindungsgemäßen Anordnung ist es, daß -bei gleichzeitigem Vorhandensein einer pneumatischen Dämpfungskammer - ein durch das hydraulische Medium geschmierter und somit dichter Abschluß des offenen Dämpferteils vorhanden ist.Such arrangements have the advantage that the chassis vibrations are less damped when driving straight ahead than when cornering. The stronger damping, especially on the outside of the bend, results in better lane keeping and a smaller cornering angle of the car body. Another advantage the arrangement according to the invention is that - with the simultaneous presence of a pneumatic damping chamber - one lubricated by the hydraulic medium and thus there is a tight seal of the open damper part.
Weiterhin wird vorgeschlagen, der Vorrichtung einen Regler zuzuordnen, der das Drosselorgan in Abhängigkeit von der Fahrgeschwindigkeit verstellt, beispielsweise bei rasch fahrendem Fahrzeug im Sinne einer Dämpfung, die um ein Mehrfaches wirksamer ist als bei langsam fahrendem Fahrzeug.It is also proposed to assign a controller to the device, which adjusts the throttle device depending on the driving speed, for example in the case of a fast moving vehicle in terms of damping, which is several times more effective than when the vehicle is moving slowly.
In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt. Es handelt sich um die Hälfte eines Querschnittes durch ein Fahrgestell eines Kraftfahrzeuges.An exemplary embodiment is shown schematically in the drawing. It is about half of a cross section through a chassis of a motor vehicle.
An den oberen Lenker I des lenkbaren Rades 2 ist der Verdrängerkolben 3 eines hydropneumatischen Schwingungsdämpfers angelenkt. Die beiden Druckkammern 4 und 5 des Zylinders 6 des Schwingungsdämpfers sind durch einen Kanal 7 miteinander verbunden, in den das eine Düse enthaltende, drehbare Drosselorgan 8 eingebaut ist. An einem Schwenkhebel 9 des Drosselorgans greift ein zu einem Schwenkhebel IO des Lenkrades II führendes Gestänge 12 an.The displacement piston is attached to the upper link I of the steerable wheel 2 3 hinged to a hydropneumatic vibration damper. The two pressure chambers 4 and 5 of the cylinder 6 of the vibration damper are connected through a channel 7 connected, in which the nozzle containing a rotatable throttle member 8 is installed. On a pivot lever 9 of the throttle member engages a pivot lever IO of the Steering wheel II leading linkage 12 on.
In dieses Gestänge wären auch Regelglieder einzuschalten, die in Abhängigkeit der Fahrgeschwindigkeit (beispielsweise in Abhängigkeit der Drehzahl einer Treibachse des Fahrzeuges) arbeiten.In this linkage would also have to switch control elements that are dependent the driving speed (for example, depending on the speed of a driving axle of the vehicle).
Der Zylinder 6 ist am Rahmen 13, der Teil des Fahrzeugaufbaues ist, befestigt. Wirkungsweise Beim Geradeausfahren ist der Kanal 7 geöffnet. Der Schwingungsdämpfer wirkt deshalb verhältnismäßig schwach. Wird am Lenkrad eine Kurvenfahrt eingeleitet, dann verkleinert das Drosselorgan 8 den Querschnitt des Kanals 7, und zwar um so mehr, je größer der Drehwinkel des Lenkrades ist.The cylinder 6 is on the frame 13, which is part of the vehicle body, attached. How it works When driving straight ahead, channel 7 is open. The vibration damper therefore acts relatively weak. If cornering is initiated on the steering wheel, then the throttle member 8 reduces the cross-section of the channel 7, in fact all the same more, the greater the turning angle of the steering wheel.
