zelaufhängurig für Omnibusse und Nutzfahrzeuge. Zweck der Erfindung ist die Herstellung einer Einzelaufhängung für Vorderräder, die weder mit der Achse n®ch in irgendeiner Weise unmittelbar mit dem Fahrgestell verbunden sind, so daß die Hader bei der Fortbewegung Beanspruchungen durch Hindernisse unabhängig voneinander dämpfen und eine Gegenreaktion auf die Schüttelbewegungen vermeiden, die infolge der von den Fahrwiebenheiten auf das Fahrgestell und damit auf das Fahrzeug einwirkenden Kräfte entstehen. Gleichzeitig wird die Kurvenneigung des Fahrzeuges durch eine Stabilisierungsstange verringert, die die beiden untereinander beweglichen Parallelogramme direkt miteinander verbindet und die Schwankungen des Fahrzeuges bremst.I "
cell suspension for buses and commercial vehicles. The purpose of the invention is to produce an individual suspension for front wheels that are not directly connected to the chassis in any way, so that the struggles during movement dampen the stresses caused by obstacles independently of one another and avoid a counter-reaction to the shaking movements, which arise as a result of the forces acting on the chassis and thus on the vehicle by the Fahrwiebenheiten. At the same time, the curve inclination of the vehicle is reduced by a stabilizing bar, which connects the two mutually movable parallelograms directly and brakes the swaying of the vehicle.

Gemäß der Erfindung ist ein Parallelogrammsystem vorgesehen, das aus zwei pendelnden Dreiecken besteht, die mit einem Gummisilentbloo im lagerbock verankert sind und mit einer Pendelstange mitAccording to the invention, a parallelogram system is provided that consists of two pendulous triangles, each with a rubber silent bloo are anchored in the bearing block and with a pendulum rod

einem Gelenk auf einem Rollenlager verbunden sind, das innen das Parallelogramm in seiner Gesamtheit, das Verbindungsstück der Stabilisierungsstange und das Verbindungsstück des Stoßdämpfers trägt und außen mit dem Achsende des Lenkaggregats"verbunden ist, wodurch alle zur Führung des Fahrzeuges erforderlichen Bewegungen bei großem Rad-einschlag mit allen auf einem gemeinsamen Lager verankerten Bewegungsorganen gemeinsam mit allen Verbindungastükken und unabhängig von der Konstruktion des Fahrgestells ermöglicht werden.a joint on a roller bearing are connected, the inside of the parallelogram in its entirety, the connecting piece of the Supports the stabilizing rod and the connecting piece of the shock absorber and is externally connected to the axle end of the steering unit ", whereby all movements required to guide the vehicle with a large wheel lock are shared with all of them anchored locomotor organs together with all connecting pieces and regardless of the construction of the chassis.

Die Erfindung wird hier mit Bezug auf eine bevorzugte Version erläuternd und nicht einschränkend aufgrund der beigefügten Zeichnungen beschrieben.The invention is illustrated here with reference to a preferred version and is not described in a restrictive manner on the basis of the accompanying drawings.

Mit Bezug auf die Zeichnungen wird die Vorderradaufhängung aus Pendeldreieuxen 1 und 1 gebildet, die mit einem Lagerboök/durch Gelenke und einen Silentbloc 3 und mit einer Pendelstange 4 durch Rollenlager 5 verbunden sind, aus einer Stabil!sierungsstange 6, die über Gummilager 7 im Fahrgestell verankert ist und entsprechende Pendelzugstangen 8 besitzt, die in einem Silentbloc 9 mit der Pendelstange verbunden sind, aus Stoßdämpfern 10, die durch einen Silentbloc 11 zwischen Pendelstange und Fahrgestell verankert sind, aus einer Luftfeder 12, die am Fahrgestell und an der Pendelstange befestigt ist, und aus dem Lenkaggregat, das aus auf dem Lagerbock angeordneten Spurstangen 13» einem transversalen Zwischenstab 14, lateralen PendelZugstangen 15 "und auf den Lenkgruppen der Räder befestigten Hebeln 16.besteht.With reference to the drawings, the front suspension is made Pendeldreieuxen 1 and 1 formed with a Lagerboök / by Joints and a Silentbloc 3 and connected to a pendulum rod 4 by roller bearings 5, from a stabilizing rod 6, which is anchored in the chassis via rubber bearings 7 and has corresponding pendulum tie rods 8, which are in a Silentbloc 9 with the pendulum rod are connected, consisting of shock absorbers 10, which are anchored by a Silentbloc 11 between the pendulum rod and the chassis are, from an air spring 12, which is attached to the chassis and the pendulum rod, and from the steering unit, the from tie rods 13 arranged on the bearing block, a transverse intermediate rod 14, lateral pendulum tie rods 15 "and on levers attached to the steering groups of the wheels.

Daraus sind folgende Vorteile ersichtlich:The following advantages can be seen from this:

- Jedes Rad läßt sich bei gleichzeitiger Dämpfung der Unebenheiten der Fahrbahn und ohne Übertragung von Schwingungen und Vibrationen auf das Fahrzeug einzeln bewegen;- Each wheel can be moved while at the same time damping the bumps move individually along the roadway and without transmitting oscillations and vibrations to the vehicle;

- Die Kurvenneigung wird merklich verringert und die Stabilisierungseigenschaften des Fahrzeuges auch bei erhöhter Geschwindigkeit auf unbekannter und unebener Fahrbahn verbessert.- The curve inclination is noticeably reduced and the stabilizing properties of the vehicle is improved even at higher speeds on unknown and uneven road surfaces.
