Description

Verbindungseinrichtung für die Deichsel oder den Führungsbügel einer VibrationsplatteConnection device for the drawbar or the guide bracket of a vibration plate
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 wesentliche horizontale, zur Fortbewegungsrichtung der Vibrationsplatte senkrechte Schwenkachse bezüglich der Vibrationsplatte verschwenkbar ist .The invention relates to a connecting device for the sprung connection of a drawbar or a guide bracket to the upper mass of a hand-held vibrating plate in such a way that the drawbar or the guide bracket can be pivoted with respect to the vibrating plate about a substantially horizontal pivot axis perpendicular to the direction of movement of the vibrating plate.
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.For the aforementioned purpose, a number of different, known connecting devices have been proposed, but all of them are either of a relatively complicated construction and are correspondingly susceptible to faults or, on the one hand, to provide good, relatively soft cushioning in the straight running of the vibrating plate with regard to the function to be performed by them, and on the other hand also to ensure precise maneuverability, to be desired.
Der Erfindung liegt die Aufgabe zugrunde, eine Verbindugnseinrich- tung zu schaffen, die die vorgenannten Funktionseigenschaften bei einfacher konstruktiver, storunanfalliger Gestaltung hervorragend erfüllt.The invention is based on the object of providing a connecting device which excellently fulfills the aforementioned functional properties with a simple design which is not susceptible to faults.
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 the connecting device two pairs arranged in the direction of the pivot axis at a fixed mutual distance, each consisting of a first connecting element in the form of a rubber buffer and a second connecting element in the form of a rubber buffer which can be slid coaxially to the pivot axis and essentially has a ring which is free from play, the one connecting element of each pair being attached to the upper mass and the other connecting element the drawbar or the guide bracket is attached.
Mit der erfindungsgemäßen Verbindungseinrichtung ist der Führungs- bügel 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 Vibrations- platte übertragen wird.With the connecting device according to the invention, the guide bracket or the drawbar can be pivoted effortlessly up and down, the ring rotating around the rubber buffer and vibrations occurring in a straight line being accompanied by slight deformations of the elastic material of the rubber buffer, to which the rubber buffer does not offer any hard resistance that good soft cushioning is guaranteed. However, if the guide bracket or the drawbar is pivoted to the side, the rings exert considerable forces acting on the rubber buffers at the spaced-apart fastening points of the pairs in opposite directions, to which these resist a relatively hard resistance, so that the steering force is very effective on the Upper mass and thus transferred to the vibrating plate.
In diesem Zusammenhang sind auch die Merkmale der Unteransprüche 4 und 5 als bevorzugte Ausgestaltungen besonders vorteilhaft, da durch sie die gewünschte weiche Federung im Geradeauslauf der Vibrationsplatte und das Einsetzen eines harten Widerstandes gegen seitliche Lenkbewegungen schon bei kleiner Auslenkung ganz besonders begünstigt wird.In this context, the features of subclaims 4 and 5 are particularly advantageous as preferred configurations, since they particularly favor the desired soft suspension in the straight running of the vibration plate and the onset of hard resistance to lateral steering movements even with a small deflection.
Die weiteren Unteransprüche betreffen ebenfalls bevorzugte vorteilhafte Ausgestaltungen der Verbindungseinrichtung gemäß Patentanspruch 1.The further subclaims also relate to preferred advantageous embodiments of the connecting device according to patent claim 1.
Die Erfindung wird nachstehend anhand der Zeichnung an einem Aus- führungsbeispiel noch näher erläutert .The invention is explained in more detail below with reference to the drawing using an exemplary embodiment.
In der Zeichnung zeigt :The drawing shows:

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 vibrating plate 1 shown in side view in FIG. 1 can be guided with a U-shaped guide bracket 3 which is attached to the upper mass 1 a of the vibrating plate 1 in the manner described below.
Wie am besten aus Fig. 2 ersichtlich, ist an die Obermasse la 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 lb 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 lb 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, a support plate 7 is rigidly attached to the upper mass 1 a at the rear end lying in the forward direction of travel, onto which a U-shaped holder 6 is fastened by means of screws 7 a in such a position that in the - In each case in a plane parallel to the direction of movement and perpendicular to the plane of the ground contact plate lb - free legs of the holder, slots 6a provided at their inward ends define a perpendicular to the normal linear direction of movement and parallel to the contact plane of the ground contact plate lb pivot axis 8 for the guide bracket 3. In the slots 6a coaxial to the pivot axis 8 threaded bolts 10a are inserted, with which a rigidly attached metallic mounting plate 10 can be clamped by means of a nut 10b against the respective free leg of the holder 6. Each of the two mounting plates 10 carries one - e.g. vulcanized - to the pivot axis 8 rotationally symmetrical rubber buffer 5, which has at its free end remote from the bracket 6 a portion 9 of slightly larger diameter than its remaining length. For clarification, the diameter ratio is exaggerated in FIG. 2.
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 rubber buffer 5 is provided with a recess 5a which is essentially coaxial with its axis of symmetry and which extends inwards from the free end face adjacent to the section 9 with an enlarged diameter over part of the length of the rubber buffer 5 extends and whose diameter decreases inward from the free end face, as a result of which the rubber buffer in the area of its section 9 of larger diameter receives a particularly large degree of flexibility in the radial direction, which is considerably greater than the flexibility of the rubber buffer immediately following the metallic fastening plate 10.
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 rubber buffers 5 are each surrounded essentially free of play by a ring 4a coaxial with the pivot axis 8, and one or the other free end of the bracket 3 is attached to the rings 4a on the circumference, e.g. welded on. In order to give the rings 4a increased dimensional stability, they each consist of the outer surface of a cup-shaped body 4. The distance between the end faces of the cup-shaped body 4 is essentially determined by the fixed distance 3 of the free legs of the guide bracket 3 and the length of the rubber buffer 5 and the depth of the cup-shaped body 4 are coordinated so that at least when driving straight, the facing end edges of the cup-shaped body 4 have some distance from the vertical webs of the U-shaped bracket 6.
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. 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.It can be seen that the sections 9 of the rubber buffers, which have a larger outer diameter than the remaining section of the rubber buffers in question, the rings 4a in the position shown in FIG. 2 of the guide bracket 3, which the latter assumes when the vibration plate 1 is traveling straight ahead Cushion the direction perpendicular to the pivot axis 8 relatively softly. On the other hand, during lateral movements of the guide bracket, one ring 4a on one side of the holder 6 is pressed against the rubber buffer 5 with great force from the bracket 3 and the other ring 4a is pulled against the rubber buffer 5 with great force on the other side from the bracket 3, so that each ring 4a comes after a relatively short distance with its inward end on the massive, the mounting plate 10 adjacent part of the rubber buffer 10 to the system and then the steering force is only slightly damped via the rubber buffer 5 to the bracket 6. In each phase of movement of the vibrating plate 1, i.e. both when driving straight ahead and when the bow is forced by means of the guide bracket 3, the guide bracket 3 can be pivoted up and down about the pivot axis 8 in contact with the rubber buffers 5, the respective ring 4a being circumferentially on the rubber buffer 5 slides along.
Die Schlitze 6a sind nötig, um die in die topfförmigen Körper 4 eingesetzten Gummipuffers 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. l 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 slots 6a are necessary in order to be able to mount the rubber buffers inserted into the pot-shaped bodies 4 on the holder 6. 3, they are aligned essentially horizontally, in such a way that they extend outward in the respective vertical leg of the holder 6 from the slot base in the direction of forward travel. This particular alignment of the slots 6a is due to the fact that vibration plates of the type depicted in FIG. 1 have an automatic advance caused by the vibration exciter, that is to say they only have to be moved and pulled in the opposite direction by means of the guide bracket 3, and that vibration plates frequently, e.g. B. to be transported from one place of use to the next, on the guide bracket 3 by hand or by means of a hoist on a transport vehicle and the guide bracket 3 must not come loose from the vibrating plate 1, even if one or the other nut on the threaded bolt 10a should have loosened something.
