Abstract

In order, in trailer combinations for reversing packers which are lifted out on supporting wheels during the reversing operation, to make it possible to lift them out reliably, even under difficult conditions, an automatic braking device which brakes the supporting wheels during the lifting-out operation is used.

Description

Die Erfindung betrifft eine Nachläuferkombination für Wendepacker, die beim Wendevorgang auf Stützräder aus­ gehoben wird.The invention relates to a trailer combination for Reversible packer that turns on support wheels during the turning process is lifted.

Nachläuferkombinationen für Wendepacker haben die Auf­ gabe, die Saatbettvorbereitung zu verbessern oder ganz auszuführen.Trailer combinations for reversible packers have the Auf gift to improve the seedbed preparation or whole to execute.

Es gibt zur Zeit die Möglichkeit, verschiedene Walzen und Gerätekombinationen an Wendepackern zu verwenden. Dazu gehören auch solche, die beim Wendevorgang auf Stützräder ausgehoben werden. (Patentanmeldung P 35 39 070.0, Gebrauchsmusteranmeldung G 85 33 165.1)There is currently the possibility of different rollers and device combinations on reversible packers. This also includes those that occur during the turning process Jockey wheels are raised. (Patent application P 35 39 070.0, utility model application G 85 33 165.1)

Bei der Möglichkeit, Nachläuferkombinationen auf Stütz­ räder auszuheben, kann es unter ungünstigen Verhältnis­ sen, wie abschüssiges Gelände, ungeeignete Bodenverhält­ nisse, sehr schwere Geräte, vorkommen, daß die Stütz­ räder kein ausreichendes Widerlager für einen einwand­ freien Aushebevorgang bilden.With the possibility of back-up combinations on support Lifting wheels can be under unfavorable proportions like sloping terrain, unsuitable ground conditions nisse, very heavy equipment, that support wheels not sufficient abutment for a perfect form free lifting process.

Aufgabe der Erfindung ist es, einen einwandfreien Aus­ hebevorgang von Nachläuferkombinationen auch unter schwie­ rigen Bedingungen zu ermöglichen.The object of the invention is to provide a flawless Lifting of trailer combinations even under difficult conditions conditions.

Diese Aufgabe wird erfindungsmäßig dadurch gelöst, daß die Stützräder während des Aushebevorganges gebremst wer­ den und bei ausgehobener Nachläuferkombination frei lau­ fen können.This object is achieved according to the invention in that the jockey wheels braked during the lifting process and when the trailer combination is lifted free can.

Die Nachläuferkombination kann so ausgeführt werden, daß der Bremsvorgang selbsttätig mechanisch geschieht.The trailer combination can be designed so that the braking process takes place mechanically.

Die Nachläuferkombination kann auch so ausgeführt werden, daß der Bremsvorgang und das Lösen der Bremse selbsttätig hydraulisch betätigt wird.The trailer combination can also be designed that the braking process and the release of the brake automatically is operated hydraulically.

Die mit der Erfindung erzielten Vorteile bestehen insbe­ sondere darin, daß Nachläuferkombinationen, die beim Wen­ devorgang auf Stützräder ausgehoben werden, auch unter schwierigen Verhältnissen verwendet werden können.The advantages achieved with the invention are in particular special in that follow-up combinations that the Wen devorgang on training wheels, also under difficult conditions can be used.

Ausführungsbeispiel 1Embodiment 1

Über den Stützrädern der Nachläuferkombination sind be­ weglich aufgehängte und federbelastete Bremsklötze ange­ bracht, die von außen auf die Lauffläche der Stützräder wirken. Die Länge der Bremsklötze ist so bemessen, daß die Stützräder am Ende des Aushebevorganges aus dem Be­ reich der Bremsklötze herausschwenken und damit frei be­ weglich werden.Be above the support wheels of the trailer combination movable and spring-loaded brake pads attached brings that from the outside to the tread of the support wheels Act. The length of the brake pads is such that the support wheels at the end of the lifting process from the loading swivel out the brake pads and be free become mobile.

Ausführungsbeispiel 2Embodiment 2

Eine an den Stützrädern vorhandene Bremse wird durch hydraulische Arbeitszylinder über eine als Puffer wir­ kende Feder betätigt. Ein anderer hydraulischer Zylinder, der beim Aushebevorgang mitbewegt wird, dient dabei als Quelle für den betätigenden Ölstrom. Die Arbeitszylinder haben einen zusätzlichen Rücklauf über ein Drosselven­ til, wodurch erreicht wird, daß die Bremswirkung nur so lange anhält, wie die zuströmende Ölmenge größer ist, als der Rücklauf durch das Drosselventil. So wird er­ reicht, daß die Bremswirkung unmittelbar mit Beendigung des Aushebevorganges aufhört, und der Wendevorgang unbe­ hindert ablaufen kann.A brake on the support wheels is applied hydraulic working cylinders we use as a buffer actuated spring. Another hydraulic cylinder, which is also moved during the lifting process serves as Source for the actuating oil flow. The working cylinders have an additional return via a throttle valve til, which ensures that the braking effect only so lasts a long time, as the inflowing amount of oil is larger, than the return through the throttle valve. So he will is enough that the braking effect immediately upon termination the lifting process stops, and the turning process continues prevents running out.
