Bei Sattelzügen nimmt die auf die Hinterachse der Zugmaschine und auf die Aufliegerachse wirkende Last mit der Höhe der aufgebrachten Nutzlast sehr stark zu. Die Last auf der Vorderachse der Zugmaschine ist dagegen von der Beladung nahezu unabhängig. Um eine gute Blockiersicherheit beim Bremsen zu erreichen, sollen daher auch die an der Hinterachse und der Aufliegerachse wirkenden Bremskräfte im Verhältnis zu der Bremskraft der Vorderachse beim leeren Sattelzug wesentlich kleiner sein als diejenigen beim beladenen Sattelzug.In the case of articulated lorries, the one acting on the rear axle of the tractor and the trailer axle Load increases with the height of the applied payload. The load on the front axle of the tractor on the other hand is almost independent of the load. In order to have a good security against blocking Braking should therefore also be achieved by those acting on the rear axle and the trailer axle Braking forces are significantly smaller in relation to the braking force of the front axle when the tractor-trailer is empty than those with a loaded tractor-trailer.
In der Praxis wird dies dadurch erreicht, daß jeweils vor dem Bremskreis der Hinterachse und der Aufliegerachse ein Regelventil eingebaut ist, welches abhängig von dem auf die jeweilige Achse wirkenden Gewicht den vom Trittplattenbremsventil kommenden Druck mindert.In practice, this is achieved in that in front of the brake circuit of the rear axle and the A control valve is installed in the trailer axle, which depends on the one acting on the respective axle Weight reduces the pressure coming from the footplate brake valve.
Diese Lösung ist insofern materialaufwendig und teuer, als sie zur üblichen Bremsanlage zusätzlich zwei Regelventile erfordert.This solution is material-intensive and expensive in that it is in addition to the conventional brake system requires two control valves.
Aufgabe der Erfindung ist es, durch einfache Mittel eine einwandfreie und billige Anordnung zur Bremskraftregelung der Sattelzüge zu erreichen. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zwischen dem Bremsventil und den Bremszylindern der Zugmaschinenhinterachse sowie denen der Aufliegerachse ein einziges von der Zugmaschinenhinterachse beeinflußtes, lastabhängiges Regelventil angeordnet ist, während die Bremszylinder der Zugmaschinenvorderachse vom Bremsventil über die Leitungen direkt beaufschlagt sind.The object of the invention is to provide a flawless and inexpensive arrangement for by simple means To achieve braking force control of the articulated lorries. According to the invention, this object is achieved by that between the brake valve and the brake cylinders of the tractor rear axle and those the trailer axle has a single load-dependent control valve influenced by the rear axle of the tractor is arranged, while the brake cylinder of the tractor front axle from the brake valve via the Lines are acted upon directly.
Ein Vorteil der Erfindung besteht darin, daß das Regelventil in der Zugmaschine angeordnet und somit eine Änderung der Bremsanlagen älterer Auflieger nicht erforderlich ist, wenn diese mit der gemäß der Erfindung ausgerüsteten Sattelzugmaschine betrieben werden. Dieser Vorteil ist sehr wesentlich, da häufig mehrere Auflieger wechselweise mit einer Zugmaschine gekuppelt werden.An advantage of the invention is that the control valve is arranged in the tractor and thus it is not necessary to change the braking systems of older trailers if they are compatible with the be operated according to the invention equipped tractor. This advantage is great essential, as several trailers are often alternately coupled to a tractor.
In der Zeichnung ist ein Ausführungsbeispiel der Anordnung einer lastabhängigen Bremseinrichtung gemäß der Erfindung näher erläutert.The drawing shows an embodiment of the arrangement of a load-dependent braking device explained in more detail according to the invention.
Die Zeichnung zeigt die Anordnung eines Regelventils 2 in einem druckluftgebremsten Sattelzug.
Hinter dem Trittplattenbremsventil 1 ist in die zum Bremskreis der Hinterachse 9 führende Bremsleitung
2 α das Regelventil eingebaut. An dem Bremskreis der Hinterachse 9 ist gleichfalls das
Anordnung einer lastabhängigen
Bremseinrichtung für SattelzügeThe drawing shows the arrangement of a control valve 2 in a tractor unit braked with compressed air. Behind the step plate brake valve 1, the control valve is installed in the brake line 2 α leading to the brake circuit of the rear axle 9. There is also a load-dependent arrangement on the brake circuit of the rear axle 9

Anhängerbremsventil 3 angeschlossen. Im Auflieger entfällt das sonst übliche Regelventil hinter dem Anhängersteuerventil 5. An Stelle dessen wird lediglich ein einfaches Löseventil 4 angeordnet.Trailer emergency valve 3 connected. The otherwise usual control valve behind the is not required in the trailer Trailer control valve 5. Instead, only a simple release valve 4 is arranged.
Wird über das Trittplattenbremsventil 1 Druckluft zum Bremsen eingesteuert, so wird diese beim leeren Zug durch das Regelventil 2 sowohl für die Hinterachse 9 als auch für die Aufliegerachse 10 im Druck im gewünschten Maß herabgemindert, da das für den Anhänger wirksame Anhängerbremsventil 3 von dem bereits geminderten Druck der Hinterachse 9 gesteuert wird.If compressed air is fed in via the footplate brake valve 1 for braking, it is released when the Train through the control valve 2 both for the rear axle 9 and for the trailer axle 10 in pressure reduced to the desired extent, since the trailer brake valve 3 effective for the trailer of the already reduced pressure of the rear axle 9 is controlled.
Mit 8 a, 8 b sind die Bremszylinder der Vorderachse 8 bezeichnet, welche in dem Bremskreis 6 angeordnet sind.The brake cylinders of the front axle 8, which are arranged in the brake circuit 6, are denoted by 8 a, 8 b.
