Abstract
Description
Die Erfindung betrifft ein Fahrzeug mit einer Bremsvorrichtung nach den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a vehicle with a braking device according to the features of the preamble of
Aus dem Stand der Technik ist, wie in der
Der Erfindung liegt die Aufgabe zugrunde, ein Fahrzeug mit einer verbesserten Bremsvorrichtung anzugeben.The invention has for its object to provide a vehicle with an improved braking device.
Die Aufgabe wird erfindungsgemäß durch ein Fahrzeug mit einer Bremsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.The object is achieved by a vehicle with a braking device with the features of
Bevorzugte Ausgestaltungen und Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments and further developments of the invention are specified in the dependent claims.
Beim Fahrzeug mit einer Bremsvorrichtung, welche zumindest ein an einer Unterseite des Fahrzeugs angeordnetes aufblasbares Element aufweist, das aus einem Ruhezustand heraus ausdehnbar ist und in einem ausgedehnten Aktivzustand eine Bremswirkung erzielt, wirkt das aufblasbare Element im ausgedehnten Aktivzustand erfindungsgemäß auf eine Bremsplatte ein und bewegt und/oder presst diese in Richtung einer Fahrbahnoberfläche, wobei an einer fahrbahnseitigen Oberfläche der Bremsplatte eine Mehrzahl von Ausformungen angeordnet sind, welche bei aktivierter Bremsvorrichtung form- und/oder kraftschlüssig in die Fahrbahnaberfläche eindringen oder eingreifen. Auf diese Weise ist eine mittels der Bremsvorrichtung erzeugbare Bremskraft signifikant erhöht, da vorteilhafterweise Verzahnungseffekte, mittels derer große Kräfte übertragbar sind, zwischen Fahrbahnoberfläche und Ausformungen der Bremsplatte effektiv genutzt werden.In the vehicle having a braking device which has at least one inflatable element disposed on a lower side of the vehicle, which is expandable from a rest state and achieves a braking effect in an extended active state, the inflatable element in the extended active state acts on a brake plate according to the invention and moves and / or presses them in the direction of a road surface, wherein on a roadway-side surface of the brake plate, a plurality of formations are arranged, which form-locking and / or non-positively penetrate or engage in the Fahrbahnaberfläche with activated braking device. In this way, a braking force which can be generated by means of the braking device is significantly increased, since gear effects, by means of which large forces can be transmitted, are effectively utilized between the road surface and the formations of the brake disk.
Das form- und/oder kraftschlüssige Eindringen der Ausformungen in die Fahrbahnoberfläche ermöglicht insbesondere auf Fahrbahnoberflächen mit verringertem Gleitreibungskoeffizienten, beispielweise nasse, mit Schnee oder Eis bedeckte und/oder unbefestigte Fahrbahnoberfläche, eine signifikant erhöhte Bremskraft.The positive and / or non-positive penetration of the formations into the road surface makes it possible, in particular on road surfaces with a reduced coefficient of sliding friction, for example wet, snow or ice covered and / or unpaved road surface, to have a significantly increased braking force.
Somit erhöhen sich für eine bestimmte Zeitdauer in gewünschter Weise die Reibungs- und Bremskräfte zwischen Kraftfahrzeug und Fahrbahnoberfläche. Der Bremsweg bis zum Stillstand des Fahrzeugs wird entsprechend kürzer.Thus, for a certain period of time increases in the desired manner, the friction and braking forces between the vehicle and the road surface. The braking distance until the vehicle stops is correspondingly shorter.
Die Bremsvorrichtung unterstützt außerdem eine Verminderung der Unfallschwere, wenn ein Unfall nicht zu vermeiden ist, da die Bremsvorrichtung Energie vor dem Unfall abbaut und während des Unfalls Energie absorbiert. Außerdem kann die Bremsvorrichtung vor allem bei einem Heckaufprall einen Bremsnickausgleich bewirken. Weiterhin kann die Bremsvorrichtung dazu beitragen, dass niedrigere Fahrzeuge bei einem Unfall nicht überfahren werden.The braking device also helps to reduce the severity of an accident when an accident is unavoidable, as the braking device dissipates energy before the accident and absorbs energy during the accident. In addition, the brake device can cause a Bremsnickausgleich especially in a rear impact. Furthermore, the braking device can help lower vehicles are not run over in an accident.
Auf diese Weise ist die Fahrzeugverzögerung signifikant verbessert oder erhöht.In this way, the vehicle deceleration is significantly improved or increased.

Des Weiteren ist durch die Einleitung der Normalkraft in die Fahrzeugstruktur ein Verringern einer Fahrzeughöhe im Frontbereich während der Fahrzeugbremsung verhindert oder zumindest vermindert, d. h. ein als sogenanntes Nicken bezeichnetes Eintauchen eines Frontbereichs des Fahrzeugs. Auf diese Weise ist beispielsweise bei einer Kollision des Fahrzeugs mit einem anderen Fahrzeug die Gefahr eines Unterfahrens des anderen Fahrzeugs reduziert, d. h. eine Kollision in einem nicht optimalen, zu tiefen Bereich am anderen Fahrzeug. Somit ist durch die Bremsvorrichtung
