Description

Es sind bereits Bodenbremsen für Kraftfahrzeuge bekannt, die in vertikaler Richtung in Schlitzführungen beweglich sind und in Betriebsstellung zwischen Räder und Fahrbahn eingreifen.There are already ground brakes for motor vehicles known in the vertical Direction in slot guides are movable and in the operating position between wheels and intervene in the road.

Diese Vorrichtungen sind aber kompliziert. Im Falle der Gefahr kann nur die einfachste Konstruktion helfen, wie sie der Erfindungsgegenstand darstellt: Sie besteht darin" daß die Bodenbremse aus einem Vorschuh und einem Hauptschuh besteht, die durch Zugfedern miteinander verbunden sind .und deren Seitenkanten beiderseits erhöht sind.However, these devices are complicated. In case of danger can only the simplest construction, as represented by the subject of the invention, helps: It consists in "that the ground brake consists of a front shoe and a main shoe, which are connected to each other by tension springs and their side edges on both sides are increased.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.

Abb. i zeigt die Vorrichtung in Ruhestellung, Abb.2 in Arbeitsstellung, Abb. 3 einen Grundriß der Vorrichtung in Arbeitsstellung, Abb. q. eine Seitenansicht des Bremsschuhes, Abb. 5 eine Draufsicht auf den Bremsschuh. Der am Fahrzeugrahmen i mittels beweglicher Rutschschiene :2 und Schlitzlasche 3 geführte Bremsschuh 4 wird durch ein an ihm befestigtes Zugseil 5, welches über Gleitrollen 6 und 7 mit einem um seinen Drehpunkt 8 beweglichen Hebel 9 verbunden ist, in seiner Ruhestellung in angespannter Lage und in einem gewissen Abstand vom Reifen io abgezogen.Fig. I shows the device in the rest position, Fig. 2 in the working position, Fig. 3 is a plan view of the device in the working position, Fig. Q. a side view of the brake shoe, Fig. 5 is a plan view of the brake shoe. The one on the vehicle frame i brake shoe 4 guided by means of a movable slide rail: 2 and slotted tab 3 is attached to it by a traction rope 5, which on rollers 6 and 7 with a lever 9 movable about its pivot point 8 is connected, in its rest position in a tense position and at a certain distance from the tire io.

Wird nun bei auftretender Schleuder- undRutschgefahr des Fahrzeuges auf vereister oder schlüpfriger Straße durch den Wagenführer die Geschwindigkeit verlangsamt, so reicht bei stark abschüssigen Straßen oder S-Kurven infolge Eigengewichts des vollbeladenen Fahrzeuges der zur Verfügung stehende Bremsweg nicht aus, um den Wagen zum Stehen zu bringen. Wird in diesem Falle der Hebel 9 gelöst, so entspannt sich das Zugseil 5, und der Bremsschuh fällt augenblicklich durch seine Schwere' nach unten und legt sich gemäß seiner Doppelanordnung rechts und links vor die Reifen io, dabei geführt an einem festen Bolzen 22 mittels der Schlitzlasche 3 der Rutschschlene 2. Die an der Unterseite des Bremsschuhes angebrachten Stahlzähne drücken sich fest in den Boden der Straße oder in die vereiste Straßendecke, hervorgerufen durch das Auflaufen der Reifen auf die Bremsschuhe 4 mit dem Eigengewicht des Fahrzeuges. Der Wagen steht augenblicklich.Is now when there is a risk of skidding and slipping of the vehicle on icy or slippery road by the driver the speed slowed down, it is enough on steeply sloping roads or S-curves due to its own weight of the fully loaded vehicle, the available braking distance is not sufficient to reduce the Bring the car to a standstill. If the lever 9 is released in this case, so relaxed the pulling rope 5, and the brake shoe falls instantly due to its weight ' down and, according to its double arrangement, lies on the right and left in front of the tires io, guided on a fixed bolt 22 by means of the slotted tab 3 of the slide slot 2. The steel teeth attached to the underside of the brake shoe press firmly into place in the ground or in the icy pavement caused by the Running of the tires on the brake shoes 4 with the weight of the vehicle. The car stops immediately.

Ist .die Schleudergefahr beseitigt, so fährt der Wagen etwas rückwärts, und die Reifen io rollen von den: Bremsschuhen 4 wieder ab. Der Hebel 9 wird wieder angezogen; und die Bremsschuhe 4 fahren über die Rutschschiene 2, durch ,die Schlitzlasche 3 geführt, wieder in .die Auflhänge- und Ruhestealun@g neben die Reifen io zurück, und zwar so weit nach oben, daß die Höhe ,der Aufhängung gleichzeitig eine kontinuierliche Abnahme ihres Eigengewichts und damit eine Entlastung des Zugseiles bedingt. Das Fahrzeug kann jetzt seine Fahrt fortsetzen.Once the risk of skidding has been eliminated, the car moves backwards a little, and the tires io roll off the brake shoes 4 again. The lever 9 is again dressed; and the brake shoes 4 drive over the slide rail 2, through the slotted tab 3, back to the suspension and resting area next to the tires, and so far upwards that the height of the suspension is continuous at the same time Reduction of their own weight and thus a relief of the pull rope. That The vehicle can now continue its journey.

Die Bremsvorrichtung ist als Zwillingsanordnung und mit einer gemeinsamem Schwenkachse 17 ausgeführt. An derselben wird bei .den Punkten 18 das gemeinsame Zugseils befestigt.The braking device is as a twin arrangement and with a common Pivot axis 17 executed. At the same point 18 the common Pull rope attached.

Der Bremsschuh besteht aus einem Hauptschuh 4 und einem Vorschuh 12. Beide haben an der Unterseite eine Verzahnungsfläche aus gehärteten Stählzähnen i i und besitzen auf ihrer Oberfläche einen aus -genopptem Gummi bestehenden Belag 13, der auf den Stahlkörper beider Schuhe aufvulkanisiert ist. Die Seitenkanten 2o sind an beiden Seiten erhöht ausgeführt, um ein seitliches Abgleiten der auflaufenden Reifen io zu verhindern. Die Achse 15 verbindet den Hauptschuh 4 mit dem Vorschuh 12, und die Zugfeder 14 bewirkt das Anziehen: des Vorsdhuhes an .den Hauptschuh in Ruhestellung bei der Aufhängung. Die Achsenführung i9 bildet eine beiderseitige Verlängerung der Schwenkachse 17 und dient als Gelenkverbindung des Hauptschuhes mit der :beweglichen Rutschschiene 2, deren Fuß in dem SegmentaussChnitt 21 beweglich geführt ist.The brake shoe consists of a main shoe 4 and a front shoe 12. Both have a toothed surface made of hardened steel teeth on the underside i i and have a nubbed rubber covering on their surface 13, which is vulcanized onto the steel body of both shoes. The side edges 2o are raised on both sides to prevent the accruing from sliding sideways Prevent tires ok. The axis 15 connects the main shoe 4 to the front shoe 12, and the tension spring 14 causes the tightening of the Vorsdhuhes to .the main shoe in rest position when hanging. The axis guide i9 forms a bilateral Extension of the pivot axis 17 and serves as an articulated connection of the main shoe with the: movable slide rail 2, the foot of which is movable in the segment recess 21 is led.

Der Bremsschuh 4 ist als Höhlkörper aus Stahl gefertigt. Die Stahlzähne sind gehärtet, und der zur Schonung der Reifen dienende Gummibelag wird auf- die Oberseite des Bremsschuhes aufvulkanisiert; um eine Haltbarkeit zu gewährleisten.The brake shoe 4 is made of steel as a hollow body. The steel teeth are hardened and the rubber covering, which is used to protect the tires, is applied Top of the brake shoe vulcanized on; to ensure durability.

Die Bremsvorrichtung kann auch durch Fernsteuerung betätigt werden.The braking device can also be operated by remote control.
