Description

Die Erfindung bezieht sich auf. einen abgefederten Traktorensitz mit Lenkerführung unter Verwendung eines Winkelhebels, an dessen einem Ende der Sitz und an dessen anderem Ende eine Schraubenfeder angreift, deren Angriffspunkt gegenüber dem Winkelhebel veränderbar ist.The invention relates to. a sprung tractor seat with Handlebar guidance using an angle lever, at one end of which the seat and a helical spring engages at the other end, the point of attack opposite the angle lever is changeable.

Die Erfindung besteht darin, daß die Schraubenfeder in einem Abstand vom Winkelhebel an e.in;em. auf diesem parallel venschieblich festgeklemmten Ausleger angreift.The invention consists in that the coil spring at a distance from the angle lever to e.in; em. on this arm that is clamped so that it can be moved in parallel attacks.

In Verfolg des Erfindungsgedankens ist der abgefederte Traktorensitz so ausgeführt, daß die Schraubenfeder eine Druckfeder ist und die Federwiderlager aus dem Boden eines Zylinders und einem in ihm gleitenden Kolben bestehen, ,der über eine Zugstange gelenkig mit dem Anlenkpunkt am Ausleger in Verbindung steht. Der Zylinder ist mittels Drehzapfen am Lagerschild schwenkbar angeordnet. An der Zugstange, welche die Feder durchsetzt, ist in an sich bekannter Weise eine Einstellmutter zwecks Veränderung der Sitzhöheneinstellung vorgesehen.In pursuit of the idea of the invention is the spring-loaded tractor seat designed so that the coil spring is a compression spring and the spring abutment consist of the bottom of a cylinder and a piston sliding in it, the is in an articulated connection with the articulation point on the boom via a tie rod. The cylinder is pivotably arranged on the bearing plate by means of pivot pins. At the The pull rod, which passes through the spring, is an adjusting nut in a manner known per se intended for changing the seat height adjustment.

Vorteilhaft .ist, daß die Druckfeder ihre Schwenklage zum Winkelhebel verändern kann,, ohne zu ecken oder zu verklemmen. Infolge des Angriffspunktes der Schraubenfeder im . Abstand vom Winkelnebel wird ein 'besonders günstiger Wirkungsgrad der Federung erreicht; schon bei kurzem Winkel-,veg ändert sich die Hebelwirkung bedeutend. Die Druckfeder fängt Stöße weich aber begrenzt ab, und außerdem wird bei einem etwaigen Bruch der Feder der Sitz nach kurzem Wege abgefangen. Federbrüche sind, also ohne nachteilige Folgen, sind aber praktisch bei der erfindungsgemäßen Ausführung mit Anordnung einer Druckfeder in einem Zylinder ernstlich kaum zu befürchten.It is advantageous that the compression spring has its pivot position relative to the angle lever can change, without jamming or jamming. As a result of the point of attack Coil spring in. Distance from the angular nebula is a 'particularly favorable efficiency the suspension achieved; even at a short angle, the leverage changes significant. The compression spring absorbs shocks softly but to a limited extent, and moreover is if the spring breaks, the seat will be intercepted after a short distance. Spring breaks are, so without adverse consequences, but are practical in the invention Execution with the arrangement of a compression spring in a cylinder is hardly to be feared seriously.

In der Zeichnung ist die Erfindung beispielsweise dargestellit.In the drawing, the invention is shown for example.

Abb. I zeigt den angefederten Traktorensitz in Seitenansicht; Abib. 2 zeigt in größerem Maßstab, .und zwar im Grundruß zu Abb. I, die schwenkbar angeordnete Federung; ' Abb. 3 zeigt die Vers tellschraube und Abb. 4 den Winkelhebel.Fig. I shows the spring-loaded tractor seat in side view; Abib. 2 shows on a larger scale, in the plan view of Fig. I, the pivotable Suspension; 'Fig. 3 shows the adjusting screw and Fig. 4 the angle lever.

In den beiden Lagerschildern a sind Lenker b an Bolzen i schwenkbar angeordnet. Der obere Lenker b bildet mit dem Verstellhebel c den Winkelhebel; wobei auf c der Ausleger d verstellbar angeordnet ist und parallel verschieblich durch. die Schraube l .in den Einkerbungen s festgeklemmt werden kann; c wird in der entsprechenden Ausnehmung p des Auslegers d geführt. Im Abstand vom Winkelhebel greift die Schraubenfeder h, welche eine Druckfeder ist, am Anlenkpunkt o an, welcher von einem Lagerbolzen gebildet wird. Die Druckfeder da ist in einem Zylinder f angeordnet und stützt sich einerseits gegen den Boden q des Zylinders, andererseits gegen einen im Zylinder gleitenden Kolben r ab, der über eine Zugstange e gelenkig mit dem Anlenkpunkt o am Ausleger d in Verbindung steht. Es ist ein Zugstangenlagerauge t vorgesehen, welches den den Anlenkpunkt darstellenden Lagerbolzen o umfaßt. Eine Einstellmutter n erlaubt die Veränderung der Sitzhöheneinstellung. Der Zylinder f .ist mittels der Drehzapfen g an den Lagerschildern a schwenkbar angeordnet. j und k stellen Auffangsicherungen dar.In the two end plates a, handlebars b are pivotably arranged on bolts i. The upper link b forms the angle lever with the adjusting lever c; where on c the boom d is adjustable and can be moved parallel through. the screw l. can be clamped in the notches s; c is guided in the corresponding recess p of boom d. At a distance from the angle lever, the helical spring h, which is a compression spring, engages the pivot point o, which is formed by a bearing pin. The compression spring da is arranged in a cylinder f and is supported on the one hand against the bottom q of the cylinder and on the other hand against a piston r sliding in the cylinder, which is articulated via a tie rod e to the articulation point o on the boom d. A tie rod bearing eye t is provided which includes the bearing pin o representing the pivot point. An adjusting nut n allows the seat height setting to be changed. The cylinder f .is arranged pivotably on the end plates a by means of the pivot pin g. j and k represent fall arrest protection.
