Die Achsbaumaße können einheitlich sein, insbesondere bezüglich Anlage, Auflage und Radanschlüssen. Das Fahrgestell kann ferner eine Leichtbaukonstruktion mit optimiertem Materialeinsatz sein.This results in trailer series with a variable chassis for different body sizes and weight ranges. The stile position can remain the same, as can the axis system. The axle dimensions can be uniform, especially with regard to the system, support and wheel connections. The chassis can also be a lightweight construction with optimized use of materials.
In den Unteransprüchen sind weitere vorteilhafte Ausgestaltungen der Erfindung angegeben. Further advantageous embodiments of the invention are specified in the subclaims.
Die Erfindung ist den Zeichnungen beispielsweise und schematisch dargestellt. Im einzelnen zeigen:The invention is shown in the drawings, for example and schematically. In detail show:
Figur 1 bis 4: verschiedene Varinaten von Fahrgestellen in Seitenansicht und Draufsicht.Figure 1 to 4: different varieties of chassis in side view and top view.
Figur 1 und 2 zeigen ein Fahrgestell (1) für einen Einachs-Anhänger in einer Seitenansicht und einerFigures 1 and 2 show a chassis (1) for a single-axle trailer in a side view and
Draufsicht. Das Fahrgestell besitzt eine V-förmige starre Zugdeichsel (2) und zwei Längsträger (6). Diese Komponenten können jeweils aus ein oder mehreren Teilen bestehen, z.B. Deichselholmen (7) und Längsholmen (8). Die Zugdeichsel (2) kann auch von den Längsträgern (6) gebildet werden. Zwischen den Längsträgern (6) können zusätzlich noch ein oder mehrere Querträger (17) eingebaut sein.Top view. The chassis has a V-shaped rigid drawbar (2) and two side members (6). These components can each consist of one or more parts, e.g. Drawbar spars (7) and longitudinal spars (8). The drawbar (2) can also be formed by the side members (6). One or more cross members (17) can additionally be installed between the longitudinal members (6).
In diesem Ausführungsbeispiel besitzt das Fahrgestell (1) eine einzelne Achse mit einem zwischen den Längsträgern (6) eingespannten Achsträger (16) und einer Schräglenkeroder Längslenkerachse mit Radachsen (3) . Vorzugsweise handelt es sich um eine Schräglenkerachse mit Breitspur.In this exemplary embodiment, the chassis (1) has a single axle with an axle bracket (16) clamped between the side members (6) and a semi-trailing arm or trailing link axle with wheel axles (3). It is preferably a semi-trailing arm with a wide track.
Das Fahrgestell (1) verfügt ferner über eine Bremsanlage (15), die z.B. aus einer Auflaufbremsanlage besteht, die über eine Zugstange oder einen Seilzug mit den Radbremsen verbunden ist. Die Zugdeichsel (2) trägt am Kopf eine Anhängerkupplung (5) von beliebig geeigneter Bauart. Im bevorzugten Ausführungsbeispiel handelt es sich um eine Kugelkopf-Anhängerkupplung, die zudem auch mit einer Reibungsbremse zur Dämpfung der Schlingerbewegungen ausgerüstet sein kann. Die wirksame Deichsellange (L) bemißt sich von dem wirksamen Kupplungspunkt der Anhängerkupplung (5) bis zu einem Radachsenbezugspunkt (4) , der beim gezeigten Einachs-Anhänger auf der Linie der Radachse (3) liegt. Die wirksame Deichsellange (L) stellt die lichte Entfernung zwischen diesen Punkten dar, wie in Figur 2 dargestellt. Der Kupplungsbezugspunkt ist beispielsweise der Mittelpunkt der Aufnahmekalotte für die Kupplungskugel.The chassis (1) also has a brake system (15) which, for example, consists of an overrun brake system which is connected to the wheel brakes via a pull rod or a cable pull. The drawbar (2) carries a trailer hitch (5) of any suitable type on the head. In the preferred embodiment, it is a ball-head trailer coupling, which can also be equipped with a friction brake to dampen the rolling movements. The effective drawbar length (L) measures from the effective coupling point of the trailer coupling (5) to a wheel axle reference point (4), which lies on the line of the wheel axle (3) in the single-axle trailer shown. The effective drawbar length (L) represents the clear distance between these points, as shown in Figure 2. The coupling reference point is, for example, the center of the dome for the coupling ball.
Die wirksame Deichsell nge (L) ist vom zulässigenThe effective drawbar length (L) is from the permissible
Gesamtgewicht des Anhängers abhängig und variiert mit diesem. Sie ist gleich oder größer als der Ergebniswert der folgenden Formel:Total weight of the trailer depends on and varies with this. It is equal to or greater than the result value of the following formula:
2,3 * 1,0004 zul.Ges.Gew..2.3 * 1,0004 Permitted total weight
Das zulässige Gesamtgewicht geht als Exponent für den Faktor 1,0004 ein. Der gewonnene Exponentialwert wird mit dem zweiten Faktor 2,3 multipliziert. Hierbei wird der Wert für das zulässige Gesamtgewicht des Anhängers in Kilogramm eingegeben, woraus sich die wirksame Deichsellange (L) in Metern errechnet.The permissible total weight is used as an exponent for the factor 1,0004. The exponential value obtained is multiplied by the second factor 2.3. The value for the permissible total weight of the trailer is entered in kilograms, from which the effective drawbar length (L) is calculated in meters.
In einer besonders bevorzugten Ausführung ergibt sich die Formel mit folgenden verfeinerten Faktoren: 2,34212 * 1,00042 zul.Ges.Gew..In a particularly preferred embodiment, the formula results with the following refined factors: 2.34212 * 1,00042 perm.total weight.
Die Maßeinheiten sind die gleichen wie bei der ersten Ausführung. Für einen Anhänger mit einem zulässigen Gesamtgewicht von 1.300 kg errechnet sich hieraus eine bevorzugte Mindest-Deichsellänge (L) von rund 4,04 m.The units of measurement are the same as in the first version. For a trailer with a permissible total weight of 1,300 kg, this results in a preferred minimum drawbar length (L) of around 4.04 m.
Innerhalb einer Anhängerbaureihe oder eines Fahrgestelltyps ergeben sich dadurch unterschiedliche wirksame Deichsellängen (L) für unterschiedliche zulässige Gesamtgewichte des Anhängers. Die veränderlichenThis results in different effective drawbar lengths (L) for different permissible total weights of the trailer within a trailer series or a chassis type. The changeable
Deichsellängen (L) können durch variable Achsbefestigungen oder durch Längenanpassungen der Längsträger (6), insbesondere der Längsholme (8), erzielt werden.Drawbar lengths (L) can be adjusted by variable axle fastenings or by adjusting the length of the side members (6), in particular the longitudinal spars (8) can be achieved.
Figur 3 zeigt eine Varinate des Einachs-Anhängers von Figur 1 mit einem im wesentlichen V-förmigen Fahrgestell (1), bei dem die Längsholme (8) ebenfalls V-förmig gespreizt sind. Im Ausführungsbeispiel von Figur 1 und 2 verliefen die Längsträger (6) parallel.FIG. 3 shows a variant of the single-axle trailer from FIG. 1 with an essentially V-shaped chassis (1), in which the longitudinal bars (8) are also spread out in a V-shape. In the embodiment of Figures 1 and 2, the side members (6) were parallel.
Figur 4 zeigt eine Anhängervariante mit einer Tandemachse. Die beiden Radachsen (3) sind ein Stück in Anhänger- Längsrichtung voneinander distanziert. Der maßgebliche Radachsenbezugspunkt (4) für die gezeigte Tandemachse liegt auf der Mittellinie zwischen den beiden Radachsen (3) . Die wirksame Deichsellange (L) bemißt sich damit bis zu diesem Radachsenbezugspunkt (4) zwischen den Radachsen (3) .Figure 4 shows a trailer variant with a tandem axle. The two wheel axles (3) are spaced apart from each other in the longitudinal direction of the trailer. The relevant wheel axis reference point (4) for the tandem axis shown lies on the center line between the two wheel axes (3). The effective drawbar length (L) is thus measured up to this wheel axis reference point (4) between the wheel axes (3).
Wie Figur 1 in der Seitenansicht verdeutlicht, kann das Fahrgestell (1) ein oder mehrere Verstellraster (12,13,14) für den variablen Anbau unterschiedlicher Teile haben. Die Verstellraster (12,13,14) sind an beiden Längsträgern (6) vorhanden und liegen mittensymmetrisch zueinander. Die Verstellraster (12,13,14) können in beliebig geeigneter Weise ausgebildet sein und bestehen z.B. aus mehreren Bohrungen, die in einer Reihe oder in einer parallelen Doppelreihe in Trägerlängsrichtung fluchtend hintereinander liegen. Statt Bohrungen können auch Anschlagpunkte, Nippel oder dergleichen andere Befestigungsmöglichkeiten vorhanden sein.As shown in Figure 1 in the side view, the chassis (1) can have one or more adjustment grids (12, 13, 14) for the variable attachment of different parts. The adjustment grids (12, 13, 14) are present on both side members (6) and are center-symmetrical to each other. The adjustment grids (12, 13, 14) can be designed in any suitable manner and consist e.g. consisting of several holes that are aligned one behind the other in a row or in a parallel double row in the longitudinal direction of the beam. Instead of holes, attachment points, nipples or the like can also be used for other fastening options.
Der vordere Verstellraster (12) dient beispielsweise zur Befestigung von Beschlagteilen für einen Aufbau (9) des Anhängers. Die Beschlagteile können z.B. abgewinkelte und ein- oder beidseitig am Steg der Längsträger (6) befestigte Flanschplatten sein, die auf der Oberseite eine Befestigungs- und Auflagefläche für den Aufbau (9) bieten. Über den Verstellraster (12) kann der Aufbau (9) gegenüber der Radachse (3) vor und zurück verschoben werden, was z.B. einen Gewichtsausgleich ermöglicht. Der erste Verstellraster (12) befindet sich beispielsweise an den Deichselholmen (7) .The front adjustment grid (12) is used, for example, to fasten fittings for a body (9) of the trailer. The fitting parts can be, for example, angled flange plates which are fastened on one or both sides to the web of the longitudinal members (6) and which provide a fastening and support surface for the structure (9) on the upper side. The structure (9) can be compared via the adjustment grid (12) the wheel axle (3) can be moved back and forth, which enables, for example, weight compensation. The first adjustment grid (12) is located, for example, on the drawbar bars (7).
Der nächste Verstellraster (13) kann an den Längsholmen (8) angeordnet sein und dient z.B. der längenverstellbaren Befestigung von Anhängerstützen (10) . Im Heckbereich kann ebenfalls ein Verstellraster (14) angeordnet sein, der für die Montage einer Heckverlängerung (11) vorgesehen ist, mit der sich die Längsträger (6) bei Bedarf und zur Anpassung an variable Aufbaulängen ein Stück nach hinten hinaus verlängern lassen. An diesem oder einem weiteren Verstellraster (14) können auch alternativ oder zusätzlich weitere Anhängerstützen (10) verstellbar befestigt werden.The next adjustment grid (13) can be arranged on the longitudinal spars (8) and serves e.g. the length-adjustable fastening of trailer supports (10). In the rear area, an adjustment grid (14) can also be arranged, which is provided for the assembly of a rear extension (11), with which the side members (6) can be extended a little to the rear if necessary and to adapt to variable body lengths. Alternatively or in addition, further trailer supports (10) can also be adjustably attached to this or a further adjustment grid (14).
Variationen der gezeigten Ausführungsbeispiele sind in verschiedener Weise möglich. Zum einen können die Fahrgestelle (1) grundsätzlich eine beliebige Form besitzen und ein oder mehrteilig ausgebildet sein.Variations of the exemplary embodiments shown are possible in different ways. On the one hand, the chassis (1) can in principle have any shape and be made in one or more parts.
Desgleichen können auch die Radachsen beliebig ausgebildet sein. Bei den Achsträgern (16) kann es sich z.B. um Gummifederachsen oder um beliebig andere Systeme handeln. Auch die Bremsanlage, die Aufbauten und die anderen Fahrgestellteile sind variabel. Die Längsträger (6) können ein biegegünstiges Längen-und Querschnittsprofil sowie gewichtssparende Ausnehmungen aufweisen. Likewise, the wheel axles can be of any design. The axle supports (16) can be, for example, rubber spring axles or any other system. The brake system, the bodies and the other chassis parts are also variable.
