Abstract

The twin axles are sprung on separate leaf springs (6) with their adjoining ends clamped by a yoke (10) between the axles to compensate for deflections of either axle. The outside ends (6") of the leaf springs are in sliding clamps. The axle mountings are on sliding fittings so that braking reactions do not twist the springs, while the axles are further supported at the ends of trailing arms (2). The axle clamps (7) on the leaf springs comprise rollers clamped above the springs and notched cams underneath, to engage grooves in the underside of the springs. If the braking reaction exceeds a set value then the twisting of the clamps disengages the grooves and allows the clamps to slide.

Description

Beschreibungdescription

zum Patentgesuch betreffend: "Doppel- und Mehrachsaggregat für Kraftfahrzeuge" Die Erfindung betrifft Doppel- und Mehrachsaggregate für Kraftfahrzeuge und Anhänger sowie Sattelanhänger mit statischem und dynamischem Achsausgleich, deren starre Achsen mit je einem Paar Schwingen über Lagerböcke gelenkig am Fahrzeugrahmen aufgehängt sind, und deren Abfederung durch auf den Achsen aufliegende Blattfederpaare erfolgt, deren einander zugekehrt liegende Federenden sich in Ausgleichswippen , die in den Lagerböcken am Fahrzeugrahmen gelagert sind, gleitend abstützen. Regarding the patent application: "Double and multi-axle unit for motor vehicles" The invention relates to double and multi-axle units for motor vehicles and trailers as well as semitrailers with static and dynamic axle compensation, their rigid Axles, each with a pair of swing arms, are hinged to the vehicle frame via bearing blocks and their cushioning takes place by pairs of leaf springs resting on the axles, whose facing spring ends are in balancing rockers, which in the Bearing blocks are mounted on the vehicle frame, support sliding.

Die Erfindung hat sich zur Aufgabe gestellt, bei derartigen Achsaggregaten zu verhindern, daß die Bremsreaktionskräfte auf die Blattfedern übertragen werden. Die Erfindung besteht im grundsätzlichen darin, daß die Blattfedern an den Achskörpehi beweglich gehaltert sind und sich auch die äußeren Federenden in Lagerböcken am Fahrzeugrahmen gleitend abstützen. The invention has set itself the task of such axle assemblies to prevent the braking reaction forces from being transmitted to the leaf springs. The invention basically consists in the fact that the leaf springs are attached to the axle bodies are movably supported and also the outer spring ends in bearing blocks on Support the vehicle frame in a sliding manner.

Dabei bestehen die Halterungen vorzugsweise aus die Blatt federn zusammenhaltenden Federbünden, die den Achsen zugekehrt liegende Nuten für den Eingriff von an den Achskörpern angebrachten Nasen aufweisen.The brackets are preferably composed of the leaf springs holding together Spring cuffs, the grooves facing the axes for the engagement of the Noses attached to the axle beams exhibit.

Durch diese vorskizzierten Halterungen wird das Verschieben der Tragfedern gegenüber den Achsen in Längsrichtung verhindert, jedoch bleibt die sonstige Beweglichkeit erhalten, d.h. Achse und Feder können sich frei gegeneinander verdrehen. These pre-sketched brackets allow the suspension springs to move prevented in relation to the axes in the longitudinal direction, but the rest of the mobility remains received, i.e. the axis and spring can rotate freely against each other.

Bei einem bevorzugten Ausführungsbeispiel der Erfindung ist über der Feder eine Rolle oder dergleichen aus elastischem Material angeordnet, die beim Springen des Fahrzeugs ein Herausgleiten der Nut aus der Nase unterbinden soll. In a preferred embodiment of the invention is over the spring a roller or the like arranged from elastic material, which when Jumping of the vehicle is intended to prevent the groove from sliding out of the nose.

Die Erfindung soll anhand der Zeichnungen näher erläutert werden. Es zeigen: Fig. 1 die Längsansicht eines Zweiachsaggregats mit statischem und dynamischem Achslastausgleich mit als Einblattfedern ausgebildetem Schwingarm, Fig. 2 und 3 vergrößerte Längs- und Querschnittdarstellungen einer Achsaufhängung gemäß Fig. 1. The invention will be explained in more detail with reference to the drawings. They show: FIG. 1 the longitudinal view of a two-axis unit with static and dynamic Axle load compensation with swing arm designed as single leaf springs, FIGS. 2 and 3 enlarged longitudinal and cross-sectional views of an axle suspension according to FIG. 1.

Am Fahrzeugrahmen 1 des Fahrzeugs sind mittels der Schwingen 2 die Achskörper 3 aufgehängt. Die Schwingen 2 sind an Lagerböcken 4, 5 des Fahrzeugrahmens 1 angelenkt. Die Federung erfolgt über Blattfedern 6, die mittig durch einen Federbund 7 zusammengehalten werden. Der Federbund weist an seiner Unterseite eine Quernut 8 auf, der am Achskörper 3 ein vorspringender Längssteg oder Nase 9 zugeordnet ist. Durch gegenseitigen Eingriff wird ein Verschieben der Blattfedern gegenüber der Achse in Längsrichtung unterbunden. On the vehicle frame 1 of the vehicle are by means of the rockers 2 Axle body 3 suspended. The rockers 2 are on bearing blocks 4, 5 of the vehicle frame 1 hinged. The suspension takes place via leaf springs 6, which are centered by a spring collar 7 are held together. The spring collar has a transverse groove on its underside 8, which is assigned a projecting longitudinal web or nose 9 on the axle body 3. Mutual engagement is a displacement of the leaf springs relative to the Axis prevented in the longitudinal direction.

Die einander zugekehrt liegenden gleitenden Federenden 6' der Blattfedern 6 stützen sich an Gleitstücken 10 von Ausgleichswippen 11 ab, die an den Lagerböcken 5 pendelnd aufgehängt sind. Die äußeren Federenden 6" stützen sich an Gleitstücken 12 an den am Tragrahmen 1 fest angebrachten Lagerböcken 4 und 14 ab. The facing sliding spring ends 6 'of the leaf springs 6 are supported on sliding pieces 10 of compensating rockers 11, which are on the bearing blocks 5 are suspended pendulum. The outer spring ends 6 ″ are supported on sliding pieces 12 on the bearing blocks 4 and 14 fixedly attached to the support frame 1.

Um vorzubeugen, daß die Eingriffsverbindung zwischen den Blattfedern und ihrer Achse beim Springen des Fahrzeugs nicht unterbrochen wird, zeigen die Fig. 2 und 3 ein elastisches Element, d.h. eine Rolle 15, die von Ständern 16 auf dem Achskörper 3 abgestützt wird und auf dem Federbund 7 federnd aufsitzt. Hierdurch sollen übermäßige Auseinanderbewegungen von Achse und Blattfedern, die zu Unterbrechungen der Eingriffsverbindung führen könnten, unterbunden werden. To prevent the meshing connection between the leaf springs and its axis is not interrupted when the vehicle jumps, the show Figs. 2 and 3 show an elastic element, i.e. a roller 15, which is supported by uprights 16 the axle body 3 is supported and is resiliently seated on the spring collar 7. Through this are intended to cause excessive movement apart of the axle and leaf springs, which lead to interruptions the engagement connection could lead to be prevented.

Es versteht sich, daß die bewegliche Befestigung zwischen Blattfedern und Achse auch durch andere Mittel bewerkstelligt werden kann. It is understood that the movable attachment between leaf springs and axis can also be accomplished by other means.
