Description

Die Erfindung betrifft eine Motorstaubremsvorrichtung mit Merkmalen wie im Oberbegriff des Anspruchs 1 angegeben.The invention relates to an engine dust brake device with features as in the preamble of claim 1 specified.

Eine solche Motorstaubremsvorrichtung ist aus der JP-A-09228854 bekannt. Hierbei ist zusätzlich zu der in der Abgasleitung angeordneten Motorbremsklappe eine diese umgehende Bypassleitung mit eingebautem Absteuerventil vorgesehen, um eine Optimierung der Motorbremskraft zu erzielen. Das Absteuerventil ist ebenso wie die Motorbremsklappe durch Befehle der Steuereinheit einstellbar. Die Bypassleitung und das zusätzliche Absteuerventil erhöhen ersichtlicherweise den Platzbedarf und die Kosten, aber auch den Regelungs- und Steuerungsaufwand für den externen Teil der Motorstaubremseinrichtung.Such an engine dust brake device is known from JP-A-09228854. in this connection is in addition to the engine brake flap arranged in the exhaust pipe immediate bypass line with built-in control valve provided to a To achieve optimization of the engine braking force. The control valve is just like that Engine brake flap adjustable by commands from the control unit. The bypass line and the additional control valve obviously increase the space requirement and the costs, but also the regulation and control effort for the external part the engine dust brake device.

Des weiteren ist aus der DE 3339053 C2 eine demgegenüber ältere und regelungstechnisch noch nicht so weit ausgebaute Motorstaubremseinrichtung bekannt. Dort ist eine in eine Abgasleitung eingebaute Motorbremsklappe mittels eines druckluftbetriebenen Stellmotors verstellbar.Furthermore, from DE 3339053 C2 is an older one and control technology Engine dust brake device not yet well developed. There is an engine brake flap built into an exhaust pipe by means of a compressed air operated one Adjustable actuator.

Ein Drucksensor, der den Abgasdruck in der Abgasleitung strömungsmäßig vor der Motorbremsklappe erfasst, ist mit einem Magnetventil verbunden, das bei Erreichen einer bestimmten Druckschwelle umschaltet und so ein druckluftgesteuertes Öffnen der Motorbremsklappe bewirkt. Eine Regelung im Sinne variabler Durchlassquerschnitte, angepasst an den jeweiligen Motorbremsleistungsbedarf, erlaubt diese bekannte Lösung jedoch nicht.A pressure sensor that measures the exhaust gas pressure in the exhaust line in front of the Engine brake flap is connected to a solenoid valve that when reached switches over a certain pressure threshold and thus a compressed air controlled opening the engine brake flap. A regulation in the sense of variable passage cross sections, adapted to the respective engine braking power requirement, this allows known Solution, however, not.

Es ist demgegenüber Aufgabe der Erfindung, eine Motorstaubremseinrichtung der gattungsgemäßen Art dahingehend zu verbessern, dass eine feinfühlige Regelung der Durchlassquerschnitte der Motorbremsklappe abhängig vom tatsächlichen Motorbremsleistungsbedarf möglich und außerdem die Motorstaubremsvorrichtung kostengünstig herstellbar und montierbar ist. It is an object of the invention, an engine dust brake device Generic type to improve that a sensitive regulation the passage cross sections of the engine brake flap depending on the actual engine brake power requirement possible and also the engine dust brake device is inexpensive to manufacture and assemble.

Dadurch, dass die Messsignale des Drucksensors und/oder Temperatursensors, gegebenenfalls auch Drehzahlsignale der Brennkraftmaschine, über die Steuereinheit der elektronischen Reglereinheit zugeführt werden, ist es möglich, anhand der eingespeicherten Kennfelder und Betriebsdaten die Ein- bzw. Verstellung der Motorbremsklappe mit einer sehr hohen Regelungsgüte zu bewerkstelligen. Zum anderen ergibt sich aufgrund der Zusammenfassung der Motorbremsklappe, deren Stellmotor und Leistungsteil sowie des Drucksensors und/oder Temperatursensors zu einem Bremsvorrichtungsmodul mit als Trägerbasis fungierendem Abgasleitungsrohrabschnitt eine bisher für solche Teile noch nie erreichte Kompaktheit mit der Möglichkeit einer günstigen, brennkraftmaschinennahen Anordnung.In the solution according to the invention, the control device is in contrast to that generic JP-A-09228854 not initially discussed, but is subordinate to an electronic controller unit. In this controller unit maps and operating data are stored. The fact that the measurement signals of the pressure sensor and / or temperature sensor, possibly also speed signals the internal combustion engine, via the control unit of the electronic regulator unit supplied, it is possible to use the stored maps and operating data the adjustment or adjustment of the engine brake flap with a very high To achieve regulation quality. Secondly, it results from the summary the engine brake flap, its servomotor and power section as well as the Pressure sensor and / or temperature sensor with a braking device module Exhaust pipe section functioning as a carrier base, one for such a hitherto Parts of compactness that have never been achieved with the possibility of an inexpensive, near-internal combustion engine Arrangement.
