Abstract

The simple emergency brake for a tractor working on a slope has a brake arm hinged (4) under the chassis. The brake arm has a hooked end (1) which is driven into the ground by a servo brake cylinder (2). The servo force can be derived from pneumatic or hydraulic supplies and the brake is operated by an emergency control in the cab. One or more brake hooks are fitted and are positioned in such a way that their deployment does not inhibit the steering of the vehicle. A controlled braking effect can be obtained by regulating the degree of deployment of the hooks by controlling the servo brake pressure.

Description

Gegenstand der Erfindung ist eine Vorrichtung, um in Notsituationen das unkontrollierte Abgleiten der o.g. Maschine im steilen Gelände zu verhindern.The invention relates to a device for the uncontrolled in emergency situations Sliding of the above Prevent machine in steep terrain.

Stand der TechnikState of the art

Die bisherige Bremsung von o.g. Maschinen erfolgt ausschließlich über die Fahrzeugräder.The previous braking of the above Machines are carried out exclusively via the vehicle wheels.

Die Bremswirkung hängt, auch bei blockierenden Rädern, ausschließlich vom Reibungsfaktor zwischen Rad und Untergrund ab.The braking effect, even with locked wheels, depends exclusively on the friction factor between the wheel and the surface.

Mangeldefect

Je nach Beschaffenheit der Geländeoberfläche, z. B. loses Geröll, nasser Boden, nasses Gras etc. sowie der Neigung des Geländes kann der Reibungsfaktor so gering werden, daß ein kontrolliertes Abfahren nicht mehr gewährleistet ist.Depending on the nature of the terrain surface, e.g. B. loose rubble, wet soil, wet grass etc. and the slope of the terrain, the friction factor can be so low that a controlled shutdown is no longer guaranteed.

Problemproblem

Der Erfindung liegt die Aufgabe zugrunde, durch eine zusätzliche Bremsvorrichtung die Bremswirkung zu vergrößern. Bei der beschriebenen zusätzlichen Bremshilfe handelt es sich um eine Notbremsvorrichtung, welche ausschließlich im Notfall benutzt werden soll, um dadurch Schaden an Leib und Leben des Fahrers, sowie weiteren Fahrzeuginsassen zu verhindern.The invention has for its object by an additional braking device Increase braking effect. The described additional braking aid is an emergency braking device, which should only be used in an emergency damage to the body and life of the driver and other vehicle occupants prevent.

Lösungsolution

Das Verfahren nach der Erfindung beruht darauf, daß eine unterhalb des Fahrzeugbodens angebrachte Bremsvorrichtung - im folgenden Bremshaken genannt - im Notfall durch Auslösen des Fahrers in die Geländeoberfläche gepreßt wird und dadurch das Fahrzeug zum Stillstand bringt.The method according to the invention is based on the fact that one below the vehicle floor attached brake device - called brake hook in the following - in an emergency Triggering the driver is pressed into the surface of the terrain and thereby the vehicle Brings to a standstill.

Eine zum Ausführen des Verfahrens verwendbare Bremsvorrichtung zeigt die Zeichnung. Zweckmäßigerweiße kann je nach Größe und Gewicht des Fahrzeugs, ein, - wie gezeichnet - zwei oder mehrere Bremshaken benutzt werden.The drawing shows a braking device that can be used to carry out the method. Depending on the size and weight of the vehicle, one can, as shown, two or more brake hooks can be used.

Die Befestigung der Bremshaken ist so gewählt, daß das Fahrzeug trotz Eindringen der Bremshaken in die Geländeoberfläche noch voll lenkbar bleibt.The attachment of the brake hook is chosen so that the vehicle despite the intrusion of Brake hook remains fully steerable in the terrain surface.

Bei einer Gefahrensituation wird durch den Fahrer über einen Nottaster der Bremsvorgang eingeleitet. Nach der Betätigung des Nottasters wird der Hubzylinder 2, der zwischen Bremshaken 1 und Fahrzeugboden 3 gelenkig 5, 6 angebracht ist, mit Druck beaufschlagt.In the event of a dangerous situation, the driver initiates the braking process using an emergency button. After actuation of the emergency button, the lifting cylinder 2 , which is articulated 5 , 6 between the brake hook 1 and the vehicle floor 3 , is pressurized.

Dieser Druck kann durch eine Hydraulikeinrichtung, Luftdruck oder Federvorspannung erzeugt werden.This pressure can be a hydraulic device, air pressure or spring preload be generated.

Der oder, je nach Größe und Gewicht des Fahrzeuges, die Bremshaken 1, welche drehbar 4 am Fahrzeugboden angebracht sind, werden dann durch Ausfahren der Kolbenstange in die Geländeoberfläche gedrückt.The or, depending on the size and weight of the vehicle, the brake hooks 1 , which are rotatably mounted 4 on the vehicle floor, are then pressed into the terrain surface by extending the piston rod.

Die Form der Haken ist so zu wählen, daß eine größt mögliche Reibung mit möglichst geringem Kraftaufwand erreicht wird.The shape of the hook should be chosen so that the greatest possible friction with little effort is achieved.

Durch den in das Gelände eingedrückten Teil des oder der Bremshaken wird der Widerstand so groß, daß das Fahrzeug zum Stillstand kommt. Die Notbremsung ist durchgeführt. Resistance is created by the part of the brake hook (s) pressed into the terrain so big that the vehicle comes to a standstill. The emergency braking has been carried out.  

Durch Verwendung eines doppeltwirkenden Hubzylinders kann durch dosiertes Herausziehen des oder der Bremshaken der Widerstand so verringert werden, daß ein gesichertes Abfahren im steilen Gelände möglich ist.By using a double-acting lifting cylinder, you can pull it out with care of the brake hook or the drag can be reduced so that a safe descent is possible in steep terrain.

Allerdings kann zu diesem Zweck nur ein Hydraulik oder luftdruckbeaufschlagte Zylinder verwendet werden. Die Steuerung erfolgt über Regelventile.However, only a hydraulic or air-pressure cylinder can be used for this purpose be used. The control takes place via control valves.
