Abstract
Druckluft-Bremsanlage (10) für Fahrzeuge, insbesondere Nutzfahrzeuge, mit beiderseits wenigstens einer Fahrzeugachse angeordneten Radbremszylindern (19,20), denen je ein von einem Bremswertgeber (11) ansteuerbarer Druckgeber (15,16) zugeordnet ist, sowie mit einer Druckgleichheit zwischen den Radbremszylindern auf den beiden Seiten der Fahrzeugachse sicherstellenden Leitung (26), in der ein die Leitung zeitweise sperrendes Ventil (27) angeordnet ist, dadurch gekennzeichnet, daß die Leitung (26) die Druckgeber (15,16) ausgangsseitig verbindet und das Ventil (27) ein vom ausgesteuerten Druck der Druckgeber betätigbares Schließglied (45) hat, welches bei Überschreiten eines Differenzdruck-Schwellenwertes das Ventil in die Sperrstellung überführt.Compressed air brake system (10) for Vehicles, especially commercial vehicles, with at least on both sides a wheel axle arranged wheel brake cylinders (19, 20), the One pressure transmitter (15, 16), each controllable by a brake value transmitter (11) is assigned, as well as with a pressure equality between the wheel brake cylinders on the two sides of the vehicle axle securing line (26), in which a valve (27) temporarily blocking the line is arranged is characterized in that the Line (26) connects the pressure transmitter (15, 16) on the output side and the valve (27) can be actuated by the modulated pressure of the pressure transmitter Locking link (45) has which if exceeded a differential pressure threshold value transfers the valve into the blocking position.

Ausgehend

Diese Aufgabe wird gelöst durch eine Druckluftbremsanlage mit den Merkmalen des Patentanspruchs 1.This Task is solved by a compressed air brake system with the features of the claim 1.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße Druckluft-Bremsanlage mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, daß der Druckausgleich auf der Arbeitsseite der Druckgeber vorgenommen und daher ein höherer Grad an Übereinstimmung des ausgesteuerten Drucks erzielt wird. Dabei ist der Druckausgleich bis zu einem Differenzdruck-Schwellenwert wirksam, der durch die von den üblicherweise vorhandenen Toleranzen der Druckgeber verursachten, voneinander abweichend ausgesteuerten Drücken der Druckgeber nicht überschritten wird. Treten jedoch den Schwellenwert überschreitende Differenzdrücke auf, wie sie beispielsweise durch das Wirksamwerden einer Schlupfregelung der Bremsanlage bei Brems- oder Antriebsschlupf verursacht werden, so verhindert das Ventil den Druckausgleich. Eine radindividuelle Bremsdrucksteuerung ist in diesem Schaltzustand des Ventils möglich.The Air brake system according to the invention with the characterizing features of claim 1 has the Advantage that the pressure equalization made on the working side of the pressure sensor and therefore a higher degree of agreement of the modulated pressure is achieved. There is pressure equalization up to a differential pressure threshold effective by the of the usual existing tolerances of the pressure sensors caused by each other differently controlled pressures the pressure transmitter is not exceeded becomes. However, if differential pressures exceed the threshold, such as the effect of a slip control the brake system is caused by brake or drive slip, the valve prevents pressure equalization. A bike individual Brake pressure control is possible in this switching state of the valve.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Patentanspruch 1 angegebenen Druckluft-Bremsanlage möglich.By those in the subclaims listed activities are advantageous developments and improvements in the claim 1 specified compressed air brake system possible.
Besonders vorteilhaft ist die im Anspruch 2 gekennzeichnete Ausgestaltung der Erfindung, weil das Ventil selbsttätig von der an der Drosselstelle herrschenden Druckdifferenz umschaltbar ist. Eines besonderen Betätigungsmittels für das Ventil bedarf es nicht. Ebenso ist bei Verwendung des Ventils eine Anpassung der Steuerelektronik nicht erforderlich.Especially The embodiment characterized in claim 2 is advantageous of the invention, because the valve automatically from the prevailing at the throttle point Pressure difference is switchable. A special actuator for the Valve is not required. There is also an adjustment when using the valve the control electronics is not required.
In den Unteransprüchen 3 und 4 sind konstruktiv einfache Ausführungsformen für das Ventil angegeben.In the subclaims 3 and 4 are given structurally simple embodiments for the valve.
Mit der im Anspruch 5 gekennzeichneten Maßnahme ist es mit nur einem Drucksensor möglich, den ausgeglichenen, in beiden Radbremszylindern herrschenden Druck zu messen. Befindet sich dagegen das Ventil in der Sperrstellung, so mißt der Drucksensor den höheren der beiden Drücke.With the measure characterized in claim 5, it is with only one Pressure sensor possible, the balanced pressure prevailing in both wheel brake cylinders to eat. However, if the valve is in the blocking position, so measure the pressure sensor the higher of the two pressures.
