Description

loser Haamann, Freudenberger Winden-und Hebezeugtabrik, Freudenberg/Main, Kirschfurt Sicherung für die Stützvorrichtun eines Sattelautliers Stützvorriohtungen für Sattelauflieger, die ähnlich einer Zahn- stangenwinde aufgebaut sind, haben Sicherungen, die das nablau- fen" der hochgefahrenen Stütze bei aufgesattelten Fahrzeug verhindern sollen. Das Herabfallen wird durch die Fahrterschütterung verursacht. Wenn die Stützvorrichtung ungewollt in der Ausfahrstellung gelangt, kann es bei leichten Bodenwellen zu Bodenberührung und zu Zerstörungen der Vorrichtung kommen. Loser Haamann, Freudenberger winch and hoist factory, Freudenberg / Main, Kirschfurt Securing device for the support device of a saddle trailer Support devices for semi-trailers, which are similar to a tooth rod winches are built, have fuses that should prevent the raised support when the vehicle is saddled up. Falling down is caused by the vibration of the vehicle. If the support device inadvertently reaches the extended position, slight bumps in the ground can result in ground contact and destruction of the device.

Die bekannten Sicherungen für Sattelauflieger-Stützvorrichtungen müssen von Hand eingelegt werden. Es kommt daher nicht selten vor, daß nach dem Autsatteln das Einlegen der Sicherung vergessen wird, zumal die Sicherung meist an Stellen angebracht sind, die nicht gut sichtbar und häufig auch schwer zugänglich sind. The well-known fuses for semi-trailer support devices must be inserted by hand. It is therefore not uncommon for people to forget to insert the fuse after the car has been saddled, especially since the fuse is usually attached to places that are not easily visible and often difficult to access are.

Der Neuerung liegt der Gedanke zugrunden, eine Sicherung zu schaffen, die so angeordnet und ausgebildet ist, daß es zur Sicherung eines besonderen Handgriffes nicht bedarf. Die Sicherung arbeitet also selbsttätig. Außerdem soll die Sicherung möglicht vor Verschmutzung geschützt sein.The innovation is based on the idea of creating a backup, which is arranged and designed so that it is used to secure a special handle not required. The fuse works automatically. In addition, the backup should be protected from contamination as much as possible.

Gemäß der Neuerung ist in Verbindung mit einer Getriebewelle im Antrieb für die Stützvorrichtung ein Teil vorgesehen, der den Umlauf dieser Welle abbremst. Um nun diese Bremskraft klein hal- ten zu können, damit diese bei der Betätigung der Stützvorrichtung nicht störte wird die bremsende bzw. haltend wirkende Einrichtung in dem Untersetzungsgetriebe an einer Stelle angeordnete die dem Bandantrieb näher als dem auf die Zahnstange wirkenden Ritzel liegt.According to the innovation, a part is provided in connection with a gear shaft in the drive for the support device, which brakes the rotation of this shaft. In order to keep this braking force small ten to be able to do so when actuating the support device The braking or holding device is not disturbed arranged in the reduction gear at a point which is closer to the belt drive than the pinion acting on the rack.

E ist vorteilhaft als Sicherungseinrichtung einen federbelasteten Stift oder bolzen vorzusehen, der mit seiner Stirnfläche auf eine in querschnitt vieleckien Abschnitt einer der Getriebewell in der Stützvorrichtung drückt. Vorzugsweise sind die Bolzen und die Feder in einem nur zur Welle offenen Gehäuse angebrachte In der Zeichnung Ist ein ausführungsbeispiel des Neuerungsgegenstandes dargestellt.E is advantageous as a safety device a spring-loaded Provide pin or bolt with its face on a cross-section polygonal section of one of the gear shaft presses in the support device. Preferably the bolts and the spring are attached in a housing that is only open to the shaft In the drawing, an exemplary embodiment of the subject of the innovation is shown.

Es zeigt : Fig 1 im Ausschnitt aus der Stützvorrichtung den Antrieb in schaubildlicher Darstellung, wobei das Gehäuse teilweise weggeschnitten ist und Fig. 2 Einzelheiten der Sicherungseinrichtung. Die Welle 1 ist mit dem Lagerzapfen 1b und le im Getriebegehäuse gelagert. Auf den Vierkant 1a kann eine Handkurbel aufgesteckt werden. Die Drehbewegung wird vom Zahnrad c über die Getriebe- zahnräder (ohne Bezugszeichen) auf die (nicht sichtbare) Zahnstange übertragen.It shows: FIG. 1, in a detail from the support device, the drive in a diagrammatic representation, the housing being partially cut away, and FIG Fig. 2 details of the safety device. The shaft 1 is with the bearing journals 1b and le in the gear housing stored. A hand crank can be attached to the square 1a will. The rotary movement is controlled by the gear wheel c via the gear Transfer gears (without reference numbers) to the (not visible) rack.

Die Ablaufsicherung besteht aus dem Bolzen 2b (vgl. auch Fig. 2) welcher in dem Gehäuse 2a ter den Druck der Feder 2e steht.The safety device consists of the bolt 2b (see. Also Fig. 2) which in the housing 2a ter is the pressure of the spring 2e.

Die Stirnfläche des Bolzens 2b drückt auf eine der Fläche des Seehskante 1d. Wenn also von der Zahnstange her eine Kraft wirkt, welche die Räder und Wellen des Getriebes zu drehen bestrebt ist# muß der Widerstand überwunden werden, welcher durch die Hubarbeit des Bolzens 2b gegen seine Feder 2c gegeben ist, wenn der Sechskannt 1d umläuft. Da nun aber im Zuge der Zahnradübertragung die Sicherung sich an einer Stelle befindet, welche mit großem Untersetzungsverhältnis gedreht wird, wenn die Bewegung von der Zahnstange her eingeleitet wird, genügt eine verhältnismäßig geringe Kraft der Feder 2c zur Sicherung. Andererseits behindert die Sicherung beim Antrieb der Welle 1 mittels der Handkurbel dieDrehbewegung nicht, The end face of the bolt 2b presses on one of the surface of the sea edge 1d. So if a force acts from the rack, which tends to turn the wheels and shafts of the gearbox, the resistance must be overcome, which is given by the lifting work of the bolt 2b against its spring 2c when the hexagon 1d rotates. Since, however, in the course of the gear transmission, the fuse is located at a point which is rotated with a large reduction ratio when the movement is initiated from the rack, one is relatively sufficient low force of the spring 2c for securing. On the other hand, handicapped the fuse when driving the shaft 1 by means of the hand crank the turning movement does not,
