Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Erhöhung einer Radlast eines Fahrzeugs bei einem Bremsvorgang nach den Merkmalen des Oberbegriffs des Anspruchs 1 und ein Verfahren zur Erhöhung einer Radlast eines Fahrzeugs bei einem Bremsvorgang nach den Merkmalen des Oberbegriffs des Anspruchs 7.The The invention relates to a device for increasing a Wheel load of a vehicle during a braking process according to the characteristics of the preamble of claim 1 and a method for increasing a wheel load of a vehicle during a braking process according to the characteristics of the preamble of claim 7.
Die maximal erreichbare Bremsverzögerung von Kraftfahrzeugen wird im Wesentlichen durch den Reibungskoeffizienten zwischen Rad und Untergrund begrenzt. Für ein heute übliches Kraftfahrzeug beträgt dabei der unter optimalen Bedingungen erreichbare Bremsweg für beispielsweise eine Verzögerung aus einer Geschwindigkeit von 100 km/h auf 0 km/h etwa 36 m. Auch wenn das Bremssystem höhere Kräfte erzeugen könnte, ist dieser Wert aufgrund der Reibungslimitierung mit konventionellen Bremsen nicht zu unterschreiten. Die Bremskraft zwischen Fahrzeug und Untergrund hängt allerdings nicht nur vom Reibungskoeffizienten ab. Ein weiterer Faktor hierbei ist die Radlast, also die Kraft, die in Richtung der Fahrzeughochachse auf das bremsende Rad einwirkt. Diese Kraft ist dabei in der Regel durch das Fahrzeuggewicht und die Achspositionen gegeben und daher nicht veränderlich. Es ist jedoch möglich, insbesondere bei Notbremsungen, mittels pyrotechnischer Vorrichtungen Rückstoßkräfte zu erzeugen, welche die Radlast und damit auch die maximal mögliche Bremskraft erhöhen.The maximum achievable braking deceleration of motor vehicles is essentially determined by the coefficient of friction between wheel and subsurface limited. For a common one today Motor vehicle is under optimal conditions achievable braking distance for example, a delay from a speed of 100 km / h to 0 km / h about 36 m. Also if the braking system could generate higher forces, this value is due to the friction limitation with conventional brakes not to fall below. The braking force between the vehicle and the ground However, not only depends on the coefficient of friction. Another factor here is the wheel load, ie the force that acting on the braking wheel in the direction of the vehicle vertical axis. This force is usually due to the vehicle weight and given the axial positions and therefore not changeable. However, it is possible, especially in emergency braking, recoil forces by means of pyrotechnic devices to generate what the wheel load and thus the maximum possible Increase braking force.
