Description
Die Erfindung bezieht sich auf eine Verbindungseinrichtung zum abgefederten Verbinden einer Deichsel oder eines Führungsbügels an der Obermasse einer handgeführten Vibrationsplatte in solcher Weise, daß die Deichsel bzw. der Führungsbügel um eine im wesentlichen horizontale, zur Fortbewegungsrichtung der Vibrationsplatte senkrechte Schwenkachse bezüglich der Vibrationsplatte verschwenkbar ist.The invention relates to a connecting device for spring-mounted connection of a drawbar or a guide bracket on the upper mass of a hand-held vibration plate in such a way that the drawbar or the guide bracket around a substantially horizontal to the direction of travel the vibration plate vertical pivot axis with respect to Vibration plate is pivotable.
Zu dem vorgenannten Zweck sind etliche verschiedene, bekannte Verbindungseinrichtungen vorgeschlagen worden, die jedoch alle entweder relativ kompliziert aufgebaut und entsprechend störanfällig sind, oder hinsichtlich der von ihnen zu erfüllenden Funktion, zum einen eine gute, relativ weiche Abfederung im Geradeauslauf der vibrationsplatte zu bewirken und zum anderen aber auch eine präzise Lenkbarkeit zu gewährleisten, zu wünschen übrig lassen.There are several different known ones for the aforementioned purpose Lanyards have been proposed, but all either relatively complex and accordingly are susceptible to interference, or with regard to the ones they have to fulfill Function, on the one hand a good, relatively soft cushioning to effect in the straight line of the vibration plate and to to guarantee others precise steering, to be desired.
Aus der US-A-4,643,611 ist eine Vibrationsplatte bekannt, bei der ein Führungsbügel über ein zur Stoßdämpfung dienendes Gummipuffer-Element an der Obermasse befestigt ist. Ähnliche Anordnungen sind auch aus der GB-A-1 018 746 und der US-A-2,771,012 bekannt.A vibrating plate is known from US-A-4,643,611 a guide bracket over a rubber buffer element used for shock absorption is attached to the upper mass. Similar Arrangements are also from GB-A-1 018 746 and the US-A-2,771,012.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbindungseinrichtung anzugeben, die die vorgenannten Funktionseigenschaften bei einfacher konstruktiver, störunanfälliger Gestaltung hervorragend erfüllt.The invention has for its object a connecting device specify the functional characteristics mentioned above with simple constructive, less prone to failure Design excellently fulfilled.
Die vorgenannte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Verbindungseinrichtung zwei in Richtung der Schwenkachse in einem festen gegenseitigen Abstand angeordnete Paare jeweils aus einem ersten Verbindungselement in Form eines Gummipuffers und einem zweiten Verbindungselement in Form eines den Gummipuffer koaxial zur Schwenkachse gleitbar sowie im wesentlichen spielfrei umgebenden Ring aufweist, wobei das eine Verbindungselement eines jeden Paares an der Obermasse und das andere Verbindungselement an der Deichsel bzw. dem Führungsbügel befestigt ist.The aforementioned object is achieved according to the invention in that that the connecting device two in the direction of Pivot axis arranged at a fixed mutual distance Pairs each from a first connecting element in the form of a Rubber buffers and a second connecting element in the form one of the rubber buffers can be slid coaxially to the swivel axis as well essentially surrounds ring free of play, the a connecting element of each pair on the Upper mass and the other connecting element the drawbar or the guide bracket is attached.
Mit der erfindungsgemäßen Verbindungseinrichtung ist der Führungsbügel bzw. die Deichsel mühelos auf und ab verschwenkbar, wobei sich der Ring um den Gummipuffer dreht und im Geradeauslauf auftretende Schwingungen mit leichten Verformungen des elastischen Materials des Gummipuffers einhergehen, denen dieser keinen harten Widerstand entgegensetzt, so daß eine gute weiche Dämpfung gewährleistet ist. Wird jedoch der Führungsbügel bzw. die Deichsel zur Seite verschwenkt, üben die Ringe an den im Abstand befindlichen Befestigungsstellen der Paare in entgegengesetzten Richtungen wirkende beträchtliche Kräfte auf die Gummipuffer aus, denen diese einen relativ harten Widerstand entgegensetzen, so daß die Lenkkraft sehr wirksam auf die Obermasse und damit auf die Vibrationsplatte übertragen wird.With the connecting device according to the invention is the guide bracket or the drawbar effortlessly pivoted up and down, whereby the ring turns around the rubber buffer and occurs in a straight line Vibrations with slight deformations of the elastic Materials of the rubber buffer go hand in hand, which this no hard Opposed resistance, so that a good soft damping ensures is. However, the guide bracket or the drawbar becomes Swiveled to the side, practice the rings on the ones in the distance Fastening points of the pairs acting in opposite directions considerable forces on the rubber buffers from which these oppose a relatively hard resistance so that the steering force very effective on the upper mass and thus on the vibration plate is transmitted.

Die Erfindung wird nachstehend anhand der Zeichnung an einem Ausführungsbeispiel noch näher erläutert.The invention is described below with the aid of an exemplary embodiment explained in more detail.
In der Zeichnung zeigt:

- Fig. 2
- die Verbindungseinrichtung im Querschnitt entlang der Schnittlinie II-II in Fig. 1, und

- the connecting device in cross section along the section line II-II in Fig. 1, and
- Fig. 3
- the bracket used in the connecting device according to FIGS. 1 and 2 in a side view for the viewer of FIG. 3 seen from the right.
Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist die
in Fig. 1 in Seitenansicht wiedergegebene Vibrationsplatte 1 mit
einem U-förmigen Führungsbügel 3 führbar, der in der nachstehend
geschilderten Weise an der Obermasse la der Vibrationsplatte 1
angebracht ist.In the embodiment shown in the drawing, the
in Fig. 1 shown in side
Wie am besten aus Fig. 2 ersichtlich, ist an die Obermasse 1a an
der in Vorwärts-Fahrtrichtung hinten gelegenen Stirnseite eine
Tragplatte 7 starr angebracht, auf die eine U-förmige Halterung 6
mittels Schrauben 7a in einer solchen Stellung befestigt ist, daß
in den - jeweils in einer zur Fortbewegungsrichtung parallelen
sowie zur Ebene der Bodenkontaktplatte 1b senkrechten Ebene gelegenen
- freien Schenkeln der Halterung vorgesehene Schlitze 6a an
ihren einwärts gelegenen Enden eine zur normalen geradlinigen
Fortbewegungsrichtung senkrechte sowie zur Kontaktebene der Bodenkontaktplatte
1b parallele Schwenkachse 8 für den Führungsbügel 3
definieren. In die Schlitze 6a sind koaxial zur Schwenkachse 8
Gewindebolzen 10a eingefügt, mit denen eine starr daran angebrachte
metallische Befestigungsplatte 10 mittels einer Mutter 10b gegen
den jeweiligen freien Schenkel der Halterung 6 verspannbar
ist. Jede der beiden Befestigungsplatten 10 trägt einen - z.B.
aufvulkanisierten - zur Schwenkachse 8 rotationssymmetrischen Gummipuffer
5, der an seinem von der Halterung 6 abgelegenen freien
Ende einen Abschnitt 9 von gegenüber seiner restlichen Länge etwas
größeren Durchmesser aufweist. Zur Verdeutlichung ist das Durchmesserverhältnis
in Fig. 2 übertrieben dargestellt.As can best be seen from FIG. 2, the upper mass is 1a
of the front end located at the rear in the forward direction of
Jeder Gummipuffer 5 ist mit einer zu seiner Symmetrieachse im wesentlichen
koaxialen Ausnehmung 5a versehen, die sich von der
freien, dem Abschnitt 9 mit vergrößertem Durchmesser benachbarten
Stirnfläche über einen Teil der Länge des Gummipuffers 5 einwärts
erstreckt und deren Durchmesser von der freien Stirnfläche einwärts
abnimmt, Dadurch erhält der Gummipuffer im Bereich seines
Abschnits 9 von größerem Durchmesser eine besonders große Nachgiebigkeit
in radialer Richtung, die erheblich größer ist als die
Nachgiebigkeit des Gummipuffers unmittelbar im Anschluß an die
metallische Befestigungsplatte 10.Each
Die Gummipuffer 5 sind jeweils im wesentlichen spielfrei von einem
zur Schwenkachse 8 koaxialen Ring 4a umgeben, und an den Ringen 4a
sind das eine bzw. andere freie Ende des Bügels 3 umfangsseitig
befestigt, z.B. angeschweißt. Um den Ringen 4a eine erhöhte Formstabilität
zu verleihen, bestehen diese jeweils aus der Mantelfläche
eines topfförmigen Körpers 4. Der Abstand zwischen den
Stirnseiten der topfförmigen Körper 4 ist im wesentlichen durch
den festen Abstand 3 der freien Schenkel des Führungsbügels 3 vorgegeben
und die Länge der Gummipuffer 5 und die Tiefe der topfförmigen
Körper 4 sind so aufeinander abgestimmt, daß zumindest bei
Geradeausfahrt die einander zugewendeten Stirnkanten der topfförmigen
Körper 4 von den vertikalen Stegen der U-förmigen Halterung
6 etwas Abstand haben.The
Es ist ersichtlich, daß die Abschnitte 9 der Gummipuffer, die einen
größeren Außendurchmesser haben als der restliche Abschnitt
des betreffenden Gummipuffers, die Ringe 4a in der in Fig. 2 zu
sehenden Stellung des Führungsbügels 3, die dieser bei Geradeausfahrt
der Vibrationsplatte 1 einnimmt, in Richtung senkrecht zur
Schwenkachse 8 verhältnismäßig weich abfedern. Hingegen wird bei
Seitenbewegungen des Führungsbügels der eine Ring 4a auf der einen
Seite der Halterung 6 vom Bügel 3 her mit großer Kraft gegen den
Gummipuffer 5 gedrückt und der andere Ring 4a auf der anderen
Seite vom Bügel 3 mit großer Kraft gegen den Gummipuffer 5 gezogen,
so daß jeder Ring 4a nach einer relativ kurzen Strecke mit
seinem einwärtigen Ende an dem massiven, der Befestigungsplatte 10
benachbarten Teil des Gummipuffers 10 zur Anlage kommt und sodann
die Lenkkraft nur wenig gedämpft über die Gummipuffer 5 auf die
Halterung 6 übertragen wird. It can be seen that the sections 9 of the rubber buffers, the one
have a larger outer diameter than the rest of the section
of the rubber buffer in question, the rings 4a in Fig. 2 to
seeing position of the
In jeder Bewegungsphase der Vibrationsplatte 1, also sowohl bei
Geradeausfahrt als auch bei mittels des Führungsbügels 3 erzwungener
Bogenfahrt, ist der Führungsbügel 3 im Kontakt mit den Gummipuffern
5 um die Schwenkachse 8 auf und niederschwenkbar, wobei
der jeweilige Ring 4a in Umfangsrichtung an dem Gummipuffer 5 entlanggleitet.In each phase of movement of the
Die Schlitze 6a sind nötig, um die in die topfförmigen Körper 4
eingesetzten Gummipuffer5 an der Halterung 6 montieren zu können.
Sie sind, wie aus Fig. 3 ersichtlich, im wesentlichen horizontal
ausgerichtet, und zwar derart, daß sie sich in dem jeweiligen vertikalen
Schenkel der Halterung 6 vom Schlitzgrund in Richtung der
Vorwärtsfahrt auswärts erstrecken. Diese besondere Ausrichtung der
Schlitze 6a ist dadurch begründet, daß Vibrationsplatten der in
Fig. 1 dargesellten Art einen vom Schwingungserreger bewirkten
selbsttätigen Vorlauf haben, also nur in der Gegenrichtung mittels
des Führungsbügels 3 bewegt, und zwar gezogen, werden müssen, und
daß Vibrationsplatten häufig, z. B. zum Transport von einem Einsatzort
zum nächsten, am Führungsbügel 3 von Hand oder mittels
eines Hebezeugs auf ein Transportfahrzeug gehoben werden und sich
der Führungsbügel 3 dabei keinesfalls von der Vibrationsplatte 1
lösen darf, selbst wenn sich die eine oder andere Mutter auf dem
Gewindebolzen 10a etwas gelockert haben sollte.The
