Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Traktions-Erhöhung bei einem Zugfahrzeug mit Sattelanhänger gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for increasing traction in a tractor with semi-trailer according to the preamble of patent claim 1.
Derartige Zugfahrzeuge mit Sattelanhänger und mit einer oder mehrerer Liftachsen sind bekannt und werden im Allgemeinen als Nutzfahrzeuge verwendet. Die Liftachsen, welche am Hinterachsaggregat des Sattelanhängers sitzen, werden vor allem bei teilbeladenem Fahrzeug zur Reifenschonung entlastet oder angehoben. Hierdurch wird der Abrieb der angehobenen Reifen verringert.Such semitrailer tractors and one or more lift axles are known and commonly used as commercial vehicles. The lift axles, which are located on the rear axle assembly of the semitrailer, are relieved or lifted, especially when the vehicle is partially laden, to protect tires. As a result, the abrasion of the raised tires is reduced.
Eine besonders wirksame Verringerung des Abtriebs ergibt sich bei Kurvenfahrten, da die Reifen bei nicht angehobenen Liftachsen bei Kurvenfahrten seitlich über die Straße bewegt werden bzw. rutschen. Hierdurch ist der Reifenabtrieb besonders stark. Dies gilt vor allem bei Hinterachsaggregaten mit weitem Radstand. Ausserdem werden dadurch die Aggregate selbst stark belastet.A particularly effective reduction of the output is obtained when cornering, since the tires are moved laterally over the road when cornering when not lifting the lift axles or slip. As a result, the tire output is particularly strong. This is especially true for Hinterachsaggregaten with a long wheelbase. In addition, the units themselves are heavily loaded.
Zur Abhilfe ist ein Verfahren und Vorrichtung zur Reifenschonung bei LKW-Sattelaufliegern bekannt (
Die vorliegende Erfindung erlaubt ebenfalls eine Reifenschonung, zielt aber hauptsächlich in eine andere Richtung. Es ist festgestellt worden, dass Zugfahrzeuge mit Sattelanhänger besonders in Kurven auf glatter Straße Traktionsprobleme bekommen können. Dies bedeutet, dass die Antriebsräder des Zugfahrzeugs durchdrehen bzw. einen erhöhten Schlupf haben, und dadurch das Zugfahrzeug den Sattelauflieger nicht mehr ausreichend bewegen kann.The present invention also allows for tire preservation but is primarily aimed in a different direction. It has been found that semitrailer tractors can experience traction problems, especially on smooth road curves. This means that the drive wheels of the towing vehicle spin or have an increased slip, and thus the towing vehicle can no longer move the semi-trailer sufficiently.
Hier greift die Erfindung ein.This is where the invention intervenes.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren für ein Nutzfahrzeug anzugeben, das aus einem Zugfahrzeug und einem Sattelanhänger besteht, durch welches bei Kurvenfahrten eine erhöhte Traktion erzielt werden kann.The invention has for its object to provide a method for a commercial vehicle, which consists of a towing vehicle and a semi-trailer, through which when cornering increased traction can be achieved.
Diese Aufgabe wird durch die im Patentanspruch 1 enthaltende Erfindung gelöst. Die Unteransprüche enthalten zweckmäßige Weiterbildungen des Erfindungsgedankens.This object is solved by the invention contained in claim 1. The dependent claims contain expedient developments of the inventive concept.
Durch die Erfindung kann der Fahrer insbesondere bei glatten Straßenverhältnissen, durch eine einmalige Aktivierung eines Fahrerschalters auf eine Fahrweise mit erhöhter Traktion in Kurven umschalten. Hierdurch wird automatisch nur bei Kurvenfahrten die Last auf den Antriebsrädern des Zugfahrzeugs erhöht, und die Traktion des Gesamtzuges dadurch in Kurven erhöht.With the invention, the driver can switch to a driving style with increased traction in curves, especially in smooth road conditions, by a one-time activation of a driver's switch. As a result, the load on the drive wheels of the towing vehicle is automatically increased only when cornering, thereby increasing the traction of the overall train in curves.
Die Erfindung wird im Folgenden anhand einer Zeichnung näher erläutert.The invention will be explained in more detail below with reference to a drawing.

Diese gewünschte Erhöhung der Last des Hinterachsaggregates
Zweckmäßig wird das erfindungsgemäße Verfahren zur Traktionserhöhung nur in einem Geschwindigkeitsbereich zwischen 0 km/h und 30 km/h angewendet. Dabei ist die Grenze von 30 km/h als ungefähre Geschwindigkeitsangabe zu betrachten. Solche Kurven, die mit Geschwindigkeiten größer als 30 km/h durchfahren werden können, haben im Allgemeinen einen geringeren Kurvenradius, sodass die erwünschte Traktionserhöhung hier nicht so wesentlich ist. Weiter soll eine zu häufige Überlastung der Achsaggregate auf 130% vermieden werden.The method according to the invention for increasing the traction is expediently used only in a speed range between 0 km / h and 30 km / h. The limit of 30 km / h is to be regarded as an approximate speed indication. Such curves, which can be traversed at speeds greater than 30 km / h, generally have a smaller turning radius so that the desired increase in traction is not so important here. Furthermore, too frequent overloading of the bogies should be avoided to 130%.
Im Geschwindigkeitsbereich über 30 km/h wird zweckmäßig durch das erfindungsgemäße Verfahren zur Traktions-Erhöhung die Liftachse
Das erfindungsgemäße Verfahren wird zweckmäßig beendet, sobald der Fahrer den Fahrerschalter
Zweckmäßig ist weiter, dass das Verfahren dann beendet wird, wenn die Kurvenerkennung für eine parametrierbare Zeitdauer ein Kurvensignal abgibt. In diesem Fall wird angenommen, dass danach die Kurve zu Ende ist, oder die Kurvenerkennung ev. defekt ist. Die Überlastung der Hinterachse
Wie bereits oben erwähnt, wird zur Kurvenerkennung die Drehzahl linker und rechter Räder einer Achse verglichen. Es können jedoch auch andere Methoden zur Kurvenerkennung verwendet werden, beispielsweise kann durch einen am Königszapfen des Zugfahrzeugs
Durch das vorgestellte erfindungsgemäße Verfahren ist es möglich, Traktion und Fahrstabilität eines aus Zugfahrzeug und Sattelanhänger bestehenden Nutzfahrzeugs während Kurvenfahrten ohne eine zusätzliche Belastung bzw. ein Tätigwerden des Fahrers wirksam zu erhöhen. Durch das häufige be- und entlüften der Luftfederbälge in allen engeren Kurven wird zwar der Luftverbrauch des Lastzuges erhöht, dieser Nachteil wird jedoch durch Schonung von Reifen und Fahrgestell ausgeglichen.The proposed method according to the invention makes it possible to effectively increase the traction and driving stability of a commercial vehicle consisting of towing vehicle and semitrailer during cornering without an additional load or intervention of the driver. Due to the frequent ventilation of the air bellows in all narrower curves, although the air consumption of the truck is increased, this disadvantage is offset by the protection of tires and chassis.
