Description
Bremsvorrichtung mit durch Gestänge geführten Bremsschuhen für Kraftwagen Die Erfindung betrifft eine Bremsvorrichtung für Kraftwagen, besonders für schwere, zur Personenbeförderung dienende Kraftwagen, wie Omnibusse, schwere Lastwagen u. dgl. Die erfindungsgemäß ausgebildete Bremsvorrichtung soll als zusätzliche Bremsvorrichtung neben den normalen Bremsen, also als eine Art Notbremse, ausgebildet und angebracht sein, die nur im Falle der Gefahr, wenn die anderen Bremsen versagen oder nicht genügend wirken, eingeschaltet wird.Braking device with brake shoes guided by rods for motor vehicles The invention relates to a braking device for motor vehicles, especially for heavy, Vehicles used for passenger transport, such as buses, heavy trucks and the like. Like. The braking device designed according to the invention is intended as an additional braking device in addition to the normal brakes, i.e. as a kind of emergency brake, designed and installed be that only in case of danger when the other brakes fail or not act enough, is switched on.
Es sind bereits durch Gestänge geführte Bremsschuhe bekannt, die nach dem Auslösen einer Verriegelung vom Führersitz aus derart unter die Räder des Wagens fallen, daß die Räder auf die Bremsschuhe auflaufen.There are already guided by linkage brake shoes known that after the release of a lock from the driver's seat under the wheels of the car fall so that the wheels hit the brake shoes.
Beim Bremsen mit den bekannten Einrichtungen vergeht eine gewisse Zeit zwischen dem vom Wagenführer gefaßten Entschluß zur Notbremsung und dem Eingreifen der Bremsschuhe zwischen Rad und Fahrbahn. Diese Zeit ist abhängig von der Dauer des Auslösevorganges der Verriegelung und von der Fallzeit der Bremsschuhe. Ein schlechter Zustand der mechanisch wirkenden und betätigten Zwischenglieder kann diese Zeitdauer verlängern.When braking with the known devices, a certain amount of time passes Time between the driver's decision to apply the brakes and the intervention the brake shoes between the wheel and the road. This time depends on the duration the release process of the lock and the fall time of the brake shoes. A poor condition of the mechanically acting and actuated intermediate links extend this period.
Der Erfindung liegt die Aufgabe zugrunde, diese kritische Zeit, die zwischen dem Entschluß des Führers zur Notbremsung und dem Eingreifen der Bremsschuhe zwischen Rad und Fahrbahn vergeht, auf ein geringstes Maß herabzusetzen. Es ist zu berücksichtigen, daß in solchen Fällen, in denen die Notbremsung erforderlich ist, oft schon Bruchteile einer Sekunde für die Vermeidung von Unfällen oder für die Herabminderung der Unfallfolgen auf ein erträgliches Maß entscheidend sind.The invention is based on the task of this critical time, the between the driver's decision to apply the brakes and the intervention of the brake shoes between wheel and road passes to reduce to a minimum. It is to take into account that in those cases where emergency braking is required is often a fraction of a second to avoid accidents or for the reduction of the consequences of the accident to a tolerable level are decisive.
Dies wird dadurch erreicht, daß der Fall der Bremsschuhe mittels einer vom Führer des Wagens im Falle der Gefahr willkürlich ferngezündeten Patrone ausgelöst und beschleunigt wird. Die Fernzündung der Patrone kann z. B. auf elektrischem Wege, also unter geringstem Kraftaufwand, erfolgen. Es ist zweckmäßig, einen Drahtseilzug vorzusehen, der in bekannter Weise ebenfalls vom Führersitz aus betätigt wird und ein schnelles Wiederheraufziehen der heruntergefallenen Bremsschuhe ermöglicht. Um ein gleichzeitiges Fallen und Wiederanheben der Bremsschuhe zu gewährleisten, können dieselben in an sich bekannter Weise mit einem Querträger verbunden sein, der gegebenenfalls mit einem Fallgewicht beschwert ist.This is achieved in that the case of the brake shoes by means of a in the event of danger, arbitrarily remote-controlled cartridge triggered by the driver of the car and is accelerated. The remote ignition of the cartridge can e.g. B. by electrical means, that is, with the least amount of force. It is convenient to use a wire rope hoist to be provided, which is also operated in a known manner from the driver's seat and enables the fallen brake shoes to be pulled back quickly. To ensure that the brake shoes fall and lift again at the same time, they can be connected to a cross member in a manner known per se, which may be weighted down with a drop weight.
Man hat bereits eine elektrische Auslösung von Bodenbremsen mit Hilfe einer elektromagnetischen Einrichtung vorgesehen. Demgegenüber ist der Erfindungsgedanke, ein Herunterfallen der Bremsschuhe in kürzester Zeit mittels einer mit einem Treibsatz gefüllten, auf elektrischem Wege ferngezündeten Patrone zu bewirken, neu. Eine solche Auslösung und Beschleunigung der Fallbewegung der Bremsschuhe bietet den Vorteil, daß die Bremsschuhe unverzüglich am Boden in die Bremsstellung gelangen.One already has an electrical release of ground brakes with the help an electromagnetic device provided. In contrast, the idea of the invention is a falling of the brake shoes in a very short time by means of a propellant filled, electrically remote-ignited cartridge, new. Such Triggering and accelerating the falling movement of the brake shoes offers the advantage of that the brake shoes come into the braking position immediately on the ground.
Es ist auch an sich bekannt, Bremsschuhe mittels einer durch Explosionsstoffe erzeugten Hilfskraft auf die Fahrbahn zu pressen. Bei einer bekannten derartigen Einrichtung wird die Hilfskraft im Falle eines Achsbruches in einer Kolben-Zylinder-Einheit erzeugt, an der der Bremsschuh fest angeordnet ist.It is also known per se to brake shoes by means of an explosive to press generated auxiliary force on the road. In a known such The facility is the auxiliary in the event of an axle break in a piston-cylinder unit generated, on which the brake shoe is fixedly arranged.
