Description

Die Erfindung ist eine Sicherung zur Unfall-und Schadensverhütung bei luftbereiften Kraftfahrzeugen, die mittels Flüssigkeit oder Luftdruck gebremst werden.The invention is a safety device for accident and damage prevention in motor vehicles with pneumatic tires that are braked by means of liquid or air pressure will.

Die Erfindung hat den Vorteil, daß auch bei plötzlich auftretender Reifenpanne der Kraftfahrer seine Fußbremse betätigen darf, ohne daß sein Fahrzeug die Bahn verläßt.The invention has the advantage that even when suddenly occurring Flat tire the driver may apply his footbrake without his vehicle leaves the train.

Schon seit Jahren ist dauernd in dieser Beziehung gearbeitet worden. Nach dem heutigen Stand der Technik kann der Kraftfahrer durch Vorrichtungen bei Eintritt von Luftverlust der Reifen gewarnt werden, und zwar entweder durch Ertönen eines Signals oder Aufleuchten einer Signallampe. Der Kraftfahrer darf aber dann nicht durch Betätigung seiner Bremsen sein Fahrzeug vorzeitig zum Halten bringen, sondern muß seine ganze Aufmerksamkeit und Fahrkunst darauf beschränken, daß sein Fahrzeug nicht aus der Bahn getragen wird. Bei der Erfindung kann der Kraftfahrer durch Betätigung der Fußbremse sein Fahrzeug auf kürzeste Entfernung zum Halten bringen. Der Wächter mit eingebautem Zylinder, Fühlstab und elektrischer Warnlampe wird leicht in jedes Bremssystem eingebaut.This relationship has been worked on continuously for years. According to the current state of the art, the driver can through devices The occurrence of a loss of air in the tires are warned, either by sounding of a signal or illumination of a signal lamp. The driver may then do not bring the vehicle to a stop prematurely by applying the brakes, but must limit all his attention and driving skills to that Vehicle is not carried off the track. In the invention, the driver can by actuating the footbrake, his vehicle is brought to a stop at the shortest possible distance bring. The guard with built-in cylinder, feeler rod and electric warning lamp is easily built into any braking system.

Bei Absinken des Reifendrucks oder bei einer Reifenpanne stößt der Fühlstab A auf die Fahrbahn oder gegen den sich erbreiternden Reifen, wodurch die Nase des Fühlstabes A den drehbaren Hebel B betätigt, wodurch ein federbelasteter Schieberzylinder C die Ölleitung D zur Bremse des Rades absperrt und ein Zylinder E frei wird, der das Öl abläßt. Der federbelastete Schieberzylinder C schließt gleichzeitig beim Absperren der Ölleitung zur Bremse einen elektrischen Kontakt, wodurch ein am Armaturenbrett des Führersitzes angebrachtes gelbes Warnlicht aufleuchtet, das dem Fahrer anzeigt, an welchem Rad der Schaden auftritt bzw. aufgetreten ist. Das durch die Reifenpanne bereits als starke Bremse wirkende Rad wird aus dem Bremssystem ausgeschaltet, wodurch die Bremswirkung nur noch auf die übrigen unbeschädigten Räder wirken kann. Durch die Gegenwirkung beim Betätigen der Bremse wird der Kraftwagen in der gewollten Richtung gehalten und kann nicht mehr aus seiner Bahn getragen werden.If the tire pressure drops or if the tire punctures, it hits Feeler rod A on the road or against the expanding tire, whereby the The nose of the feeler rod A actuates the rotatable lever B, whereby a spring-loaded Slide cylinder C blocks the oil line D to the brake of the wheel and a cylinder E is released, which drains the oil. The spring-loaded slide cylinder C closes at the same time when the oil line to the brake is shut off, an electrical contact is made, which causes a yellow warning light on the dashboard of the driver's seat illuminates shows the driver on which wheel the damage is occurring or has occurred. That The wheel, which is already acting as a strong brake when the tire has a flat tire, is removed from the braking system switched off, whereby the braking effect only affects the remaining undamaged Wheels can act. Due to the counteraction when the brake is applied, the vehicle is held in the intended direction and can no longer be carried out of its path will.

Die Vorrichtung schaltet auch dann das beschädigte Rad aus dem Bremssystem aus, wenn es bereits unter Bremsdruck steht. Der Zylinder E dient besonders diesem Fall und hat die Bestimmung, das Bremsöl des beschädigten Rades aufzunehmen, wodurch die Bremswirkung aufgehoben wird.The device then also disengages the damaged wheel from the braking system off when it is already under braking pressure. The cylinder E is especially useful for this Case and has the purpose of including brake oil of the damaged wheel, whereby the braking effect is canceled.

Nach Beheben der Reifenpanne kann der Apparat von Hand durch Niederdrücken des Hebels B in seine Normallage gebracht werden, wodurch das Warnlicht am Armaturenbrett erlischt.After the puncture has been repaired, the device can be opened by pressing it down by hand lever B to its normal position, causing the warning light on the dashboard goes out.

Der Apparat ist für jedes Rad getrennt anzubringen und kann mittels Bremsschlauchs in jedes Bremssystem eingebaut werden. Der Fühlstab A ist elastisch und verstellbar, so daß er jedem Wagentyp angepaßt werten kann.The device must be attached separately for each wheel and can be operated using Brake hose must be installed in every brake system. The feeler rod A is elastic and adjustable so that it can be adapted to any type of car.
