Abstract

The aim of the invention is to simplify a connection of a supporting plate (8), which is pivotally connected to the end of a supporting element of a jack via a joint, whereby a spring places the supporting plate (8) into a starting angular position relative to the supporting element and any starting angle can be predetermined. To this end, the spring is provided in the form of a spiral spring (17) with ends (18, 19) tangentially leading out from the spirals (16), whereby each of the ends (18, 19) is respectively connected to a fixing point of the supporting plate (8) or of the supporting element.

Description

Anbindung einer schwenkbaren TragplatteConnection of a swiveling support plate
Beschreibungdescription
Die Erfindung betrifft die Anbindung einer schwenkbaren Tragplatte an einen Wagenheber nach dem Oberbegriff des Anspruchs 1.The invention relates to the connection of a pivotable support plate to a jack according to the preamble of claim 1.
Tragplatten an Wagenhebern, die am Ansetzpunkt unter den Boden eines anzuhebenden Fahrzeuges angesetzt sind, sind häufig quer zur Fahrzeuglängsrichtung schwenkbar an den entsprechenden Tragelementen des Wagenhebers angebunden. Dadurch wird eine eindeutige Anlage der Tragplatte unter das Fahrzeug, unabhängig von der Stellung des Wagenhebers in Richtung auf die Fahrzeugmitte und unabhängig von der Höhe des angehobenen Fahrzeuges, gewährleistet.Carrier plates on jacks, which are attached at the attachment point under the floor of a vehicle to be lifted, are often pivotally connected to the corresponding support elements of the jack, transversely to the longitudinal direction of the vehicle. This ensures a clear contact of the support plate under the vehicle, regardless of the position of the jack towards the center of the vehicle and regardless of the height of the raised vehicle.
Nach dem DE-GM 74 14 229 ist es bekannt, über zwischen der Tragplatte und dem Tragelement angebundene Zug- oder Druckfedern eine bestimmte Ausgangswinkellage der Tragplatte zum Tragelement einzustellen.According to DE-GM 74 14 229 it is known to set a certain initial angular position of the support plate relative to the support element via tension or compression springs connected between the support plate and the support element.
Nachteilig bei dieser Ausbildung gestaltet sich die Anbindung der Feder äußerst aufwändig, insbesondere dann, wenn bei grundsätzlich gleichen Wagenhebertypen unterschiedliche Ansetzpunkte für die Tragplatte unter dem Fahrzeug vorgesehen werden sollen. Dieses trifft besonders dann zu, wenn bei gleichen Fahrzeugtypen, beispielsweise werksmäßig das Fahrzeug tiefer gelegt wird oder bei Off-Road-Fahrzeugen, eine größere Bodenfreiheit verlangt wird. Für die Abwandlung derartiger Wagenheber sind unterschiedliche Anlenkpunkte an der Tragplatte bzw. am Tragelement vorzusehen, was die Fertigung und Lagerhaltung für derartige Wagenheber verteuert. Der Erfindung liegt die Aufgabe zugrunde, die Anbindung einer schwenkbaren Tragplatte an das Tragelement eines Wagenhebers, bei dem der Ausgangswinkel der Tragplatte zum Tragelement beliebig vorbestimmt werden kann, zu vereinfachen.The disadvantage of this design is that the connection of the spring is extremely complex, in particular if, in the case of basically the same jack types, different attachment points are to be provided for the support plate under the vehicle. This is particularly true when greater ground clearance is required for the same vehicle types, for example the vehicle is lowered at the factory or for off-road vehicles. For the modification of such jacks, different articulation points are to be provided on the support plate or on the support element, which increases the cost of manufacture and storage for such jacks. The invention has for its object to simplify the connection of a pivotable support plate to the support element of a jack, in which the starting angle of the support plate to the support element can be predetermined as desired.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen sind in den Ansprüchen 2 bis 4 beschrieben.This object is achieved by the features of claim 1. Advantageous training and further developments are described in claims 2 to 4.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass der vorgesehene Ansetzwinkel der Tragplatte zum Tragelement nur durch den Winkel zwischen den Enden der Wendelfeder bestimmt wird. Die Anlenkpunkte sowohl an der Tragplatte als auch am Tragelement bleiben gleich. Des Weiteren ist eine wesentlich einfachere Montage der Feder möglich, da die tangential abstehenden Enden der Wendelfeder nur in die vorzugsweise als Löcher, Durchdringungen oder Blechlaschen ausgebildeten Befestigungspunkte an der Tragplatte bzw. am Tragelement eingeschoben werden müssen. Besonders bei der Ausbildung der Tragplatte aus Kunststoff können derartige Löcher oder Durchdringungen direkt mit in das Teil eingebracht werden. Bei der Ausbildung des Schwenkgelenks als Bolzen der Laschen der Tragplatte und des Tragelements durchdringt, kann weiterhin vorteilhaft die Wendelfeder mit ihren Wendeln den Bolzen umschlingend eingebaut werden. Bei dieser vorteilhaften Ausbildung wird auch eine exakte zentrale Fixierung der Wendelfeder erreicht.The advantages achieved with the invention consist in particular in that the intended angle of attachment of the support plate to the support element is determined only by the angle between the ends of the helical spring. The articulation points on both the support plate and the support element remain the same. Furthermore, a much simpler assembly of the spring is possible since the tangentially protruding ends of the helical spring only have to be inserted into the fastening points on the support plate or on the support element, which are preferably designed as holes, penetrations or sheet metal brackets. Such holes or penetrations can be made directly in the part, particularly when the support plate is made of plastic. When the swivel joint is designed as a bolt penetrating the tabs of the support plate and the support element, the helical spring with its spirals can advantageously also be installed so as to wrap the bolt. With this advantageous design, an exact central fixation of the helical spring is also achieved.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben. Es zeigenAn embodiment of the invention is shown in the drawing and is described in more detail below. Show it
Fig. 1 einen Schwenkarmwagenheber in zusammengeklappter Lage und in Ansetzposition, Fig. 2 einen Wagenheber gemäß Fig. 1 in der höchsten Hubposition, Fig. 3 die vergrößerte Darstellung des Hubendes eines Wagenhebers nach Fig. 1 und Fig. 4 die Frontansicht von Fig. 3. Der nachfolgend beschriebene Schwenkarmwagenheber ist nur eine Art von Wagenhebern. Die Erfindung ist jedoch bei allen Arten von Wagenhebern einsetzbar, insbesondere dann, wenn der Ansetzpunkt am Fahrzeug sich gegenüber dem Tragelement des Wagenhebers vom Anlagewinkel her beim Anheben bewegt.1 shows a swivel arm jack in the folded position and in the attachment position, FIG. 2 shows a jack according to FIG. 1 in the highest lifting position, FIG. 3 shows the enlarged view of the lifting end of a jack according to FIG. 1 and FIG. 4 shows the front view of FIG. 3 , The swivel arm jack described below is only one type of jack. However, the invention can be used with all types of jacks, particularly when the attachment point on the vehicle moves relative to the support element of the jack from the contact angle when lifting.
Fig. 1 und 2 zeigen einen Schwenkarmheber mit einem Standbein 1 und über ein Gelenk 2 drehbeweglich an diesem angebundenen Tragarm 3 als Tragelement. Über eine Gewindespindel 4 wird der Tragarm 3 gegenüber dem Standbein 1 angehoben. Das Standbein 1 steht mit einem Standfuß 5 auf dem Boden 6 auf. Am freien Ende des Tragarms 3 ist schwenkbeweglich über eine in Fahrzeuglängsrichtung verlaufende Schwenkachse 7 eine Tragplatte 8 angeordnet, die in eine unter dem Fahrzeugboden angeordnete Aufnahme 9 angesetzt wird und das Fahrzeug anhebt.1 and 2 show a swivel arm lifter with a support leg 1 and rotatably connected to this support arm 3 as a support element via a joint 2. The support arm 3 is raised relative to the supporting leg 1 via a threaded spindle 4. The leg 1 stands on the floor 6 with a base 5. At the free end of the support arm 3, a support plate 8 is arranged so as to be pivotable about a pivot axis 7 extending in the longitudinal direction of the vehicle, which is placed in a receptacle 9 arranged under the vehicle floor and lifts the vehicle.
In Fig. 1 ist der Tragarm in zwei Stellungen dargestellt. Die unterste Stellung zeigt den Wagenheber in der zusammengefahrenen Stellung, wie er im Fahrzeug verstaut wird. Die obere Stellung zeigt den Wagenheber in der Ansetzposition, und zwar in der Position mit unbeladenem Fahrzeug und heilem Reifen. In dieser Position muss der Wagenheber am häufigsten angesetzt werden, beispielsweise beim Reifenwechsel von Sommerreifen auf Winterreifen. Dieses ist auch die Position, in der, wie nachfolgend beschrieben, die Null-Stellung des Winkels zwischen Tragplatte 8 und Tragarm 3 definiert ist.In Fig. 1, the support arm is shown in two positions. The lowest position shows the jack in the closed position as it is stowed in the vehicle. The upper position shows the jack in the attachment position, namely in the position with the vehicle unladen and the tire healthy. In this position, the jack must be positioned most frequently, for example when changing from summer to winter tires. This is also the position in which, as described below, the zero position of the angle between the support plate 8 and support arm 3 is defined.
In Fig. 2 wird der Wagenheber in seiner höchsten Hubposition gezeigt.In Fig. 2 the jack is shown in its highest lifting position.
Wie insbesondere aus den Fig. 3 und 4 ersichtlich, läuft der Tragarm 3 an seinem freien Ende in zwei Laschen 10, 11 aus, die von einem Bolzen 12, die Schwenkachse 7 bildend, durchdrungen werden. Der Bolzen 12 durchdringt auch an der Tragplatte 8 angeordnete Laschen 13, 14. Die Tragplatte ist als Spritzgussteil aus einem harten und hochfesten Kunststoff hergestellt. Sie weist einen ebenen, seitlich abgerundeten Kopf 15 auf. Dieser Kopf 15 läuft nach unten in die vorerwähnten zwei Laschen 13, 14 aus, die von dem ebenfalls vorerwähnten Bolzen 12 durchdrungen werden, sodass die Tragplatte 8 schwenkbeweglich am Tragarm 3 befestigt ist. Zwischen den Laschen 13, 14 entsteht ein Freiraum. Dieser Freiraum dient zur Aufnahme der Wendel 16 der Wendelfeder 17. Die Wendel 16 umschlingen den Bolzen 12 mit einem gewissen Abstand, damit sie nicht auf dem Bolzen 12 klemmen, wenn die Wendelfeder zusammengedreht wird. Die Wendelfeder 17 läuft in zwei Enden 18, 19 aus, die sich tangential aus den Wendeln 16 der Wendelfeder 17 erstrecken. Eines dieser Enden 18 wird in eine in die Tragplatte 8 eingebrachte Bohrung 20 gesteckt. Von daher ist die Wendelfeder 17 kraftschlüssig mit der Tragplatte 8 verbunden. Das andere Ende 19 der Wendelfeder 17 wird durch eine aus der Stirnwand 21 des Tragarms 3 ausgeprägte Lasche 22 gesteckt. Somit ist die Wendelfeder ebenfalls kraftschlüssig mit dem Tragarm 3 verbunden.As can be seen in particular from FIGS. 3 and 4, the support arm 3 ends at its free end in two tabs 10, 11, which are penetrated by a bolt 12, which forms the pivot axis 7. The bolt 12 also penetrates tabs 13, 14 arranged on the support plate 8. The support plate is made as an injection molded part from a hard and high-strength plastic. It has a flat, laterally rounded head 15. This head 15 runs down into the aforementioned two tabs 13, 14, which are penetrated by the aforementioned bolt 12, so that the Support plate 8 is pivotally attached to the support arm 3. A free space is created between the tabs 13, 14. This free space serves to accommodate the helix 16 of the helical spring 17. The helix 16 loops around the bolt 12 at a certain distance so that they do not jam on the bolt 12 when the helical spring is turned together. The helical spring 17 ends in two ends 18, 19 which extend tangentially from the helices 16 of the helical spring 17. One of these ends 18 is inserted into a bore 20 made in the support plate 8. Therefore, the helical spring 17 is non-positively connected to the support plate 8. The other end 19 of the helical spring 17 is inserted through a tab 22 formed from the end wall 21 of the support arm 3. Thus, the coil spring is also non-positively connected to the support arm 3.
Der Winkel der Enden 18, 19 zueinander, der im Ausführungsbeispiel geringfügig von 180° abweicht, bestimmt die Winkelstellung der Tragplatte 8 zum Tragarm 3 bei unbelastetem Wagenheber. Dieses ist vorzugsweise die Ansetzstellung des Wagenhebers unter das Fahrzeug, wie sie weiter vorne beschrieben ist.The angle of the ends 18, 19 to one another, which deviates slightly from 180 ° in the exemplary embodiment, determines the angular position of the support plate 8 with respect to the support arm 3 when the jack is not loaded. This is preferably the position of the jack under the vehicle, as described above.
Sobald die Tragplatte 8 vom Fahrzeuggewicht belastet wird, legt sie sich in jeder Schwenk- und Hubpositon des Fahrzeuges bzw. des Tragarmes oder des Wagenhebers plan unter die Gegenfläche in der Aufnahme 9 unter dem Fahrzeugboden. Dieses erfolgt auch, wenn die Ansetzposition des Wagenhebers tiefer liegt wie die vorher definierte, also auch bei defektem Reifen und/oder beladenem Fahrzeug. Die Federkraft ist so ausgelegt, dass die Wendelfeder stets vom Fahrzeuggewicht auf- oder zugedreht wird, ohne eine wesentliche Federkraft zu erzeugen. Sobald der Wagenheber jedoch wieder entlastet ist, schwenkt die Feder die Tragplatte 8 stets in die ursprünglich vorgesehene Ansetzstellung zurück.As soon as the support plate 8 is loaded by the vehicle weight, it lies flat in any swiveling and lifting position of the vehicle or the support arm or the jack, under the counter surface in the receptacle 9 under the vehicle floor. This also takes place if the jack position is lower than the one previously defined, i.e. also if the tire and / or loaded vehicle are defective. The spring force is designed so that the coil spring is always turned on or off by the vehicle weight without generating any significant spring force. However, as soon as the jack is relieved, the spring always pivots the support plate 8 back into the originally intended attachment position.
Die vorbeschriebene Lösung weist den Vorteil auf, dass die unbelastete Winkellage der Tragplatte 8, bezogen auf den Tragarm 3, beliebig, nur von der Form der Wendelfeder 17 bestimmt, eingestellt werden kann. Die Winkellage kann sich in beiden Richtungen durch Öffnen oder Schließen der Wendel 16 der Wendelfeder 17 den Erfordernissen anpassen. Die Montage der Tragplatte 8 an den Tragarm 3 gestaltet sich äußerst einfach. Nach Einstecken des einen Endes 19 der Wendelfeder 17 in die Lasche 22 der Stirnwand 21 des Tragarms 3 wird die Tragplatte 8 mit ihrer Bohrung 20 auf das andere Ende 18 der Wendelfeder 17 gesteckt. Dabei schieben sich die Laschen 13, 14 der Tragplatte 8 zwischen die Laschen 10, 11 des Tragarms 3. Danach wird der Bolzen 12 durch die Bohrungen in den Laschen 10, 11, 13, 14 und die Wendel 16 der Wendelfeder 17 gesteckt und an dem nicht mit einem Kopf 23 versehenen Ende 24 verstemmt oder vernietet.The solution described above has the advantage that the unloaded angular position of the support plate 8, based on the support arm 3, can be set as desired, only determined by the shape of the helical spring 17. The angular position can adapt to the requirements in both directions by opening or closing the helix 16 of the helical spring 17. The mounting of the support plate 8 on the support arm 3 is extremely simple. After inserting one end 19 of the helical spring 17 into the tab 22 of the end wall 21 of the support arm 3, the support plate 8 is inserted with its bore 20 onto the other end 18 of the helical spring 17. The tabs 13, 14 of the support plate 8 slide between the tabs 10, 11 of the support arm 3. Then the bolt 12 is inserted through the holes in the tabs 10, 11, 13, 14 and the coil 16 of the coil spring 17 and on the not with a head 23 provided end 24 caulked or riveted.
Im Ausführungsbeispiel ist die vom Bolzen 12 durchdrungene Bohrung 25 durch die Laschen 13, 14 der Tragplatte 8 als Langloch ausgebildet. Dadurch wird vorteilhaft erreicht, dass die Tragplatte 8 gegenüber dem Tragarm 3 in Fahrzeuglängsrichtung in Grenzen kippen kann. Das bewirkt, dass durch Neigung des Fahrzeuges nach vorne oder nach hinten oder durch Längsbewegung des Fahrzeuges keine seitlichen Knickkräfte auf den Wagenheber erzeugt werden. In the exemplary embodiment, the bore 25 penetrated by the bolt 12 through the tabs 13, 14 of the support plate 8 is designed as an elongated hole. It is thereby advantageously achieved that the support plate 8 can tilt relative to the support arm 3 in the vehicle longitudinal direction within limits. This has the effect that no lateral buckling forces are generated on the jack by tilting the vehicle forward or backward or by longitudinal movement of the vehicle.
