Abstract
Description
Die vorliegende Erfindung betrifft eine Bremsanlage für einen Anhänger ziehenden Kraftwagen, ähnlich der im eigenen Gebrauchmuster 201 11 795.9 vorbeschriebenen Bremsanlage. Dieser Kraftwagen kann eine Zugmaschine, ein Traktor, ein Lastwagen, ein Kleinlastwagen, insbesondere aber einen Personenkraftwagen sein. Der Anhänger kann ein üblicher zwei- oder mehrachsiger Anhänger mit einer lenkbaren Vorderradachse, ein landwirtschaftliches Gerät, insbesondere aber ein einachsiger oder mit einer Tandemachse versehener Anhänger, wie ein Anhänger für Kleintransporte, ein Wohnwagen oder ein Bootsanhänger sein.The present invention relates to a braking system for a trailer pulling motor vehicles, similar the braking system described in the own sample 201 11 795.9. This motor vehicle can be a tractor, a tractor, a truck, a small truck, but especially a passenger car. The trailer can be a common one biaxial or multi-axle trailer with a steerable front wheel axle, an agricultural implement, in particular but a uniaxial or tandem axle trailer, like a follower for small transports, a caravan or a boat trailer his.
Bei zwei- oder mehrachsiger Anhänger greift die vorliegende Erfindung in die üblicherweise vorhandenen Einkreis- oder Zweikreis Einleitungsdruckluftbremsen ein. Alle Anhängerbremsen werden so ausgebildet, dass beim abgekoppelten Anhänger oder ungewolltem Abreißen des Anhängers vom ziehenden Fahrzeug der Anhänger gebremst ist oder wird. Die oben genannten leichten Anhänger werden mittels einer Auflaufbremse abgebremst. Hierbei wird die Auflaufkraft des Anhängers auf das Zugfahrzeug zum Bremsen benutzt. Als Ansprechschwelle dienen Federn oder hydraulische Stoßdämpfer. Die Federn oder andere Druckspeicher werden im gezogenen Zustand gespannt oder aufgeladen und der entsprechende Druck wird beim Bremsen als Bremskraftverstärker freigegeben.In the case of biaxial or multi-axle trailers, the grips present invention in the usual existing single-circuit or dual-circuit air brakes on. All trailer brakes are designed so that when the trailer is disconnected or unwanted tearing off of the trailer from the trailer pulling vehicle is or will be braked. The above light trailers are made using an overrun brake braked. Here the overrun force of the trailer used on the towing vehicle for braking. Springs serve as the response threshold or hydraulic shock absorbers. The Springs or other pressure accumulators are tensioned when pulled or charged and the corresponding pressure is applied when braking Brake booster Approved.
Im eigenen Gebrauchmuster 201 11 795.9 sind die Nachteile dieser Bremsen insbesondere bei Talfahrten beschrieben. Diese sollen dadurch überwunden werden, dass die Bremse des Anhängers vom Zugfahrzeug aus insbesondere von Hand, jedenfalls unhängig vom sonstigen Bremssystem steuerbar ist. Damit soll erreicht werden, dass der Anhänger allein und unabhängig vorn Zugfahrzeug gebremst werden kann, beispielsweise bei Talfahrten. Bekannt ist, dass zur Bestimmung der Bremswirkung von Anhängern, also zu Test- oder Prüfzwecken, nur der Anhänger bremst, während das ziehenden Fahrzeug gegen diese Bremse des Anhängers solange weiterfährt, bis der Zug zum Stillstand kommt. An sich sind weiterhin Systeme bekannt, die eine Voreilung der Anhängerbremsung automatisch bewirken. Diese Systeme setzen jedoch voraus, dass eine Abbremsung des Zugfahrzeuges eingeleitet wird, die dann verzögert einsetzt. Der Nachteil ist, dass die Verzögerung des ganzen Zuges etwas später einsetzt. Damit wird zwar der Schleudergefahr des Anhängers entgegen gewirkt, aber der Bremsweg verlängert.In own utility model 201 11 795.9 are the disadvantages of these brakes, especially when driving downhill described. These should be overcome by the fact that Brake of the trailer from Traction vehicle, especially by hand, regardless of the other braking system is controllable. This is to achieve that the trailer alone and independently can be braked in front of the towing vehicle, for example when driving downhill. Known is that to determine the braking effect of trailers, so for test or inspection purposes, only the trailer brakes while the pulling vehicle continues to drive against this brake of the trailer until the train comes to a standstill. Systems are known per se, which lead the trailer braking automatically effect. However, these systems require that a Braking of the towing vehicle is initiated, which then begins with a delay. The disadvantage is that the delay of the whole train a little later starts. This counteracts the trailer's risk of skidding knitted, but the braking distance extended.
Um diesem Umstand entgegen zu wirken, wird erfindungsgemäß zunächst allgemein vorgeschlagen, ein Abbremsen des Hängers bereits dann angemessen einzuleiten, wenn der Fahren des Zugfahrzeuges den Fuß vom Gaspedal nimmt. Im dem Augenblick setzt für das Zugfahrzeug eine Verzögerung durch den in der Drehzahl abfallenden Motors ein und es besteht die Gefahr, insbesondere wenn eine starke Feder gegen das Auflaufen wirkt, dass der dann noch im wesentlichen noch ungebremste Anhänger beginnt, aus zu brechen. Das Merkmal, das Abbremsen angemessen einzuleiten bedeutet, einen Ausgleich zwischen dem Fahr- und Rollverhalten von Zugfahrzeug und Anhänger in dieser Fahrsituation zu schaffen. Anders ausgedrückt, die dann bereits einsetzende Bremswirkung unterstützt die Motorbremse, besonders wenn heruntergeschaltet wird. Dies ist insbesondere für Fahrer nützlich, die nur selten mit einem Hänger, einem Wohnwagen, einem Boots- oder Pferdeanhänger fahren und für diesen Fahrzustand ungeübt sind. Folgt auf diese beliebig lange Fahrsituation eine erneutes Beschleunigen, durch Betätigung des Gaspedals, löst sich auch wieder die Vorbremsung des Anhängers. Folgt dagegen eine Betätigung des Trittplatten – Bremsventils über das Bremspedal im ziehenden Fahrzeug, dann schließt die normale Abbremsung des Anhängers übergangslos an die Vorbremsung an.To counteract this, According to the invention, generally first suggested braking the trailer appropriately initiate when driving the towing vehicle's foot off the accelerator takes. At the moment sets for the towing vehicle a delay by the engine dropping in speed and there is the danger, especially if a strong spring prevents it from running up has the effect that the trailer, which is still essentially unbraked, begins Break out. The characteristic of initiating braking appropriately means a balance between the driving and rolling behavior of Towing vehicle and trailer to create in this driving situation. In other words, the the braking effect that already starts supports the engine brake, especially when downshifting. This is especially for drivers useful, rarely with a trailer, drive a caravan, boat or horse trailer and for this Driving condition inexperienced are. This is followed by another driving situation of any length Accelerate through actuation of the accelerator pedal the braking of the trailer again. Conversely, an operation of the Footplate - brake valve over the Brake pedal in the pulling vehicle, then the normal braking of the Trailer seamlessly to the pre-braking.
In Verwirklichung des allgemeinen Erfindungsgedankens, kann das Gaspedal mit einem Drucksensor versehen werden, der genau registriert, ob das Gaspedal betätigt oder losgelassen wird. Es ist aber auch möglich, an dem Regelgestänge vom Gaspedal zum Regelorgan oder am Regelorgan, sei dies ein Vergaser oder eine Einspritzeinrichtung, den Gaspedalzustand abzugreifen.Realizing the general According to the concept of the invention, the accelerator pedal can be provided with a pressure sensor be registered, exactly whether the accelerator pedal is pressed or is released. But it is also possible to use the control linkage from the accelerator pedal to the regulator or to the regulator, be it a carburetor or a Injector to tap the accelerator pedal condition.
Der Anhänger kann erfindungsgemäß in Kombination mit der neuen Einrichtung in der Zugmaschine mit einem Bremssteuergerät, einem Servo-Stellmotor, einer pneumatischen oder hydraulischen Scheibenbremsanlage mit Handbremseinrichtung, Beladungssensor und Bremskraftverstärker mit Servopumpe ausgestattet sein.According to the invention, the trailer can be used in combination with the new device in the tractor with a brake control unit, one Servo-control motor, a pneumatic or hydraulic disc brake system with handbrake device, Load sensor and brake booster equipped with a servo pump his.
Mit der Erfindung wird ein rechtzeitiges und dosiertes Einbremsen des Anhängers automatisch und auf einfache Weise gewährleistet.With the invention, a timely and controlled braking of the trailer guaranteed automatically and easily.
Die Bremskräfte können entweder über die vorgespannten Federn einer Auflaufbremse gewonnen werden, wobei ein Elektromagnet einen dosierten Federweg freigibt und ein Servomotor eine Rückstellung vornimmt. Die Stromversorgung erfolgt über das Kabel zum Zugfahrzeug, welches auch die am Gashebel gewonnenen Steuerimpulse liefert. Bei pneumatischen oder hydraulischen Bremsen am Hänger werden die Bremskräfte von einem Druckvorrat abgerufen, der über eine von den Radnaben angetriebene Pumpe nachgefüllt werden kann, wenn keine Schlauchverbindung zum ziehenden Fahrzeug möglich oder erwünscht ist.The braking forces can either be over the preloaded Springs of an overrun brake are obtained using an electromagnet releases a metered spring travel and a servomotor a reset performs. Power is supplied via the cable to the towing vehicle, which also delivers the control impulses gained on the throttle. With pneumatic or hydraulic brakes on the trailer become the braking forces from a pressure supply, which is driven by a wheel hub Pump refilled can be, if no hose connection to the pulling vehicle is possible or he wishes is.
Bei einer durch Freigeben des Gaspedals verzögerten Fahrt erfolgt kein frühzeitiges Auflaufen des Anhängers und der Bremsweg wird verkürzt.When driving decelerated by releasing the accelerator pedal there is no early Accumulation of the trailer and the braking distance is shortened.
