Abstract

A servo tilt control for the roll over protection frame for a tractor cab has a hydraulic ram secured on the tractor with one end and has the other end linked to part of the frame using an adjustable clamp. When the ram is operated it tilts the frame about a pivot axis, with the tilt action aided by a universal coupling between the ram and the clamp. The servo can be fitted to most types of tilting frames and eliminates the large manual effort required to move the frames. The fittings are adjustable to suit the design of vehicle and frame and the ram is coupled to the available hydraulic circuit on the vehicle.

Description

BEZEICHNUNG: Bügelklappvorrichtung, insbesondere fürDESCRIPTION: Handlebar folding device, especially for

Traktoren Die Erfindung betrifft eine Bügelklappvorrichtung,insbesondere für Traktoren. Tractors The invention relates to a bracket folding device, in particular for tractors.

Aus Gründen der Betriebssicherheit für den Fahrer von Traktoren sind diese entweder mit überrolifesten Fahrerhäusern oder aber mit Überrollbügeln versehen. Für bestimmte Verwendungsbereiche, wie z.B.For reasons of operational safety for the driver of tractors these either with roll-over cabs or with roll bars. For certain areas of use, such as

beim Obstbau, ist es erforderlich, den Überrollbügel in die horizontale Ebene herunterklappen zu können. Üblicherweise sind in diesen Fällen die allgemein U-förmig ausgebildeten Überrollbügel am Traktorenrahmen um Drehachsen manuell schwenkbar angeordnet. Dieses hat den Nachteil, daß das Schwenken des Überrollbügels einen verhältnismäßig großen Kraftaufwand erfordert und deshalb insbesondere für Traktorfahrerinnen unangenehm ist.When growing fruit, it is necessary to put the roll bar in the horizontal position To be able to fold down the level. Usually in these cases the are general U-shaped roll bar on the tractor frame can be manually pivoted about axes of rotation arranged. This has the disadvantage that the pivoting of the roll bar one Requires a relatively large amount of effort and therefore especially for tractor drivers is uncomfortable.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zu schaffen, mittels derer der Überrollbügel von Traktoren motorisch verschwenkt werden kann.The object of the invention is to create a device by means of which the roll bar of tractors can be pivoted by motor.

Erfindungsgemäß erfolgt die Lösung der Aufgabe dadurch, daß der Überrollbügel mit dem Stellglied eines Hydraulikzylinders gelenkig verbunden ist, der an einer am Traktor angeordneten Halterung gelenkig befestigt ist. Der Hydraulikzylinder kann mittels eines am Fahrerstand befindlichen Steuergliedes betätigt und von der bordeigenen Hydraulikanlage mit Drucköl beaufschlagt werden.According to the invention, the object is achieved in that the roll bar is articulated to the actuator of a hydraulic cylinder, which is attached to a mounted on the tractor bracket is articulated. The hydraulic cylinder can be operated by means of a control member located at the driver's cab and from the on-board hydraulic system can be pressurized with pressure oil.

Weitere Merkmale der Erfindung sind in den Unteransprüchen beschrieben und werden im Folgenden anhand des in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert.Further features of the invention are described in the subclaims and are described below using the exemplary embodiment shown in the drawing closer explained.

Die Bügelklappvorrichtung 10 besteht im wesentlichen aus einem Hydraulikzylinder 6 mit einem axial verschieblichen Stellglied 5. An dem dem Stellglied 5 abgewandten Endabschnitt des Hydraulikzylinders 6 ist dieser mit einer am Traktorrahmen befestigten Halterung 7 verbunden. Die Verbindung erfolgt mittels eines Gelenkes 11, das durch einen vorzugsweise aus nicht rostendem Werkstoff bestehenden Bolzen 12 besteht, um den der Hydraulikzylinder 6 schwenkbar ist.The bracket folding device 10 consists essentially of a hydraulic cylinder 6 with an axially displaceable actuator 5 The end portion of the hydraulic cylinder 6 is attached to the tractor frame with a Bracket 7 connected. The connection is made by means of a joint 11, which through a bolt 12 preferably made of rustproof material, around which the hydraulic cylinder 6 can be pivoted.

Das Stellglied 5 ist mittels eines Bolzens 14 mit einer Klemmeinrichtung 8 verbunden. Der Bolzen 14, der ebenfalls vorzugsweise aus einem nicht rostenden Werkstoff besteht, bildet ein Gelenk 13, um das die Klemmeinrichtung 8 schwenkbar ist. Die Klemmeinrichtung 8 ist mittels eines Schraubbolzens 15 an dem Überrollbügel 1 befestigt. Der Überrollbügel 1 ist um eine Drehachse 4 schwenkbar, die an einem am Traktor befestigten Haltestück 3 ausuebildet ist. Durch axiale Verschiebung des Stellgliedes 5 kann der Überrollbügel 1 von einer horizontalen Stellung 16 in eine vertikale Stellung 17 geschwenkt werden. Das Zurückschwenken des Überrollbügels 1 erfolgt durch Umsteuerung der Druckbeaufschlagung des Arbeitskolbens in dem Hydraulikzylinder 6. Dieser weist hierzu zwei Anschlußstücke auf, an denen Anschlußleitungen 8,9 befestigt werden können. Vorzugsweise wird in wenigstens einer Anschlußleitung 8,9 ein Drosselventil angeordnet. durch das die Schwenkgeschwindigkeit des Überrollbügels 1 über den Schwenkbereich von 900 vermindert wird.The actuator 5 is by means of a bolt 14 with a clamping device 8 connected. The bolt 14, which is also preferably made of a rustproof Material consists, forms a joint 13 about which the clamping device 8 is pivotable is. The clamping device 8 is on the roll bar by means of a screw bolt 15 1 attached. The roll bar 1 is pivotable about an axis of rotation 4, which is on a Retaining piece 3 attached to the tractor is formed. Axial displacement of the Actuator 5, the roll bar 1 from a horizontal position 16 in a vertical position 17 can be pivoted. Swinging back the roll bar 1 takes place by reversing the pressurization of the working piston in the hydraulic cylinder 6. For this purpose, this has two connecting pieces to which connecting lines 8, 9 are attached can be. A throttle valve is preferably used in at least one connection line 8, 9 arranged. by the swivel speed of the roll bar 1 over the swivel range is reduced from 900.

Die Bügelklappvorrichtung 10 dient als Erweiterung bzw. Zusatz für an landwirtschaftlichen Traktoren vorhandene Sicherheitsumsturzbügel. Sie ermöglicht für den Traktorfahrer eine große Erleichterung im Betrieb, da der Überrollbügel 1 vom Sitz aus mittels eines nicht näher dargestellten Steuergliedes betätigt werden kann. Eine Beeinträchtigung der Festigkeit des Überrollbügels 1 erfolgt nicht, da das Steuerglied 5 mittels einer Klemmeinrichtung 8 mit dem Überrollbügel 1 verbunden wird. Eine Festigkeitsbeeinträchtigung des Überrollbügels 1 , wie sie bei einer Schweißverbindung erfolgen würde, tritt also nicht ein.The bracket folding device 10 serves as an extension or addition for Safety roll bars present on agricultural tractors. It enables a great relief for the tractor driver during operation, as the roll bar 1 can be operated from the seat by means of a control member not shown in detail can. The strength of the roll bar 1 is not impaired because the control member 5 is connected to the roll bar 1 by means of a clamping device 8 will. A strength impairment of the roll bar 1, as in a Welded connection would take place, so does not occur.

Das für den Hydraulikzylinder 6 erforderliche Druckmittel kann von der am Traktor befindlichen Hydraulikanlage abgezweigt werden.The pressure medium required for the hydraulic cylinder 6 can from the hydraulic system on the tractor.

Es ist möglich, die Anschlußleitungen von der bordeigenen Hydraulikanlaae mittels flexibler Schläuche mit den Anschlußstücken des Hydraulikzylinders 6 zu verbinden.It is possible to use the connection lines from the on-board hydraulic system by means of flexible hoses with the connecting pieces of the hydraulic cylinder 6 associate.
