Description

Die Erfindung bezieht sich auf einen Drosselklappenstutzen, insbesondere für einen Verbrennungsmotor eines Kraftfahrzeugs, mit einer durchgehenden Drosselöffnung für eine auf einer Drosselklappenwelle schwenkbar angeordnete Drosselklappe und mit einem Gehäuse, wobei das Gehäuse einen Gehäusedeckel und einen Gehäusekörper umfasst, wobei in dem Gehäuse zum Verschwenken der Drosselklappenwelle ein elektrischer Stellantrieb und eine erste Elektronik angeordnet sind. Die Erfindung bezieht sich weiterhin auf ein Elektronikmodul, das Elektronik für ein Kraftfahrzeug und ein von einem Deckelelement verschließbares Basiselement umfasst, wobei das Kraftfahrzeug eine Vielzahl von elektrischen Geräten und einen Drosselklappenstutzen aufweist, wobei der Drosselklappenstutzen ein Gehäuse mit einer durchgehenden Drosselöffnung für eine auf einer Drosselklappenwelle schwenkbar angeordnete Drosselklappe und einen in dem Gehäuse angeordneten elektrischen Stellantrieb zum Verschwenken der Drosselklappenwelle umfaßt.The invention relates to a throttle body, in particular for an internal combustion engine of a motor vehicle, with a continuous throttle opening for a throttle valve shaft pivotally mounted throttle and a housing, wherein the housing comprises a housing cover and a housing body, wherein in the housing for pivoting the throttle shaft an electric actuator and a first electronics are arranged. The invention further relates to an electronics module comprising electronics for a motor vehicle and a base element closable by a cover element, the motor vehicle having a plurality of electrical devices and a throttle body, the throttle body having a housing with a continuous throttle opening for one on a throttle shaft pivotally arranged throttle and arranged in the housing electric actuator for pivoting the throttle shaft comprises.

Zur Steuerung der dem Verbrennungsmotor eines Kraftfahrzeugs zuzuführenden Frischgasmenge werden üblicherweise Drosselklappenstutzen eingesetzt. Drosselklappenstutzen umfassen ein Gehäuse mit einer durchgehenden Drosselöffnung und ein in der Drosselöffnung angeordnetes Drosselorgan. Das Drosselorgan nimmt für den Durchlass einer bestimmten Frischgasmenge eine bestimmte Stellung in der Drosselöffnung ein. Hierzu ist das Drosselorgan mechanisch oder elektronisch ansteuerbar.For controlling the amount of fresh gas supplied to the internal combustion engine of a motor vehicle usually throttle body are used. Throttle body includes a housing with a continuous throttle opening and arranged in the throttle opening throttle body. The throttle body occupies a certain position in the throttle opening for the passage of a certain amount of fresh gas. For this purpose, the throttle body can be controlled mechanically or electronically.

Die Drosselklappe eines Drosselklappenstutzens kann in einem Teilbereich, zum Beispiel dem Leerlaufbereich, von einem Stellantrieb bewegbar und im restlichen Bereich mit Hilfe eines an das Gaspedal des Kraftfahrzeugs gekoppelten Drahtseiles bewegbar sein. Alternativ kann die Drosselklappe jedoch auch in ihrem gesamten Verstellbereich von einem Stellantrieb bewegbar sein. Bei diesen letztgenannten Systemen gibt es keine mechanische Verbindung zwischen der Sollwertvorgabe, insbesondere dem Gaspedal, und der Drosselklappe. Ausgelöst durch das Niederdrücken des Gaspedals wird bei diesen sogenannten E-Gas- oder drive-by-wire-Systemen die Leistungsanforderung in ein elektrisches Signal umgesetzt. Das elektrische Signal wird einer Steuereinheit zugeführt, die wiederum aus dem elektrischen Signal ein Ansteuersignal für den Stellantrieb erzeugt.The throttle valve of a throttle body may be movable in an area, for example the idling area, by an actuator and movable in the remaining area by means of a wire cable coupled to the gas pedal of the motor vehicle. Alternatively, however, the throttle valve may also be movable by an actuator in its entire adjustment range. In these latter systems, there is no mechanical connection between the set point specification, in particular the accelerator pedal, and the throttle valve. Triggered by the depression of the accelerator pedal in these so-called E-gas or drive-by-wire systems, the power requirement is converted into an electrical signal. The electrical signal is supplied to a control unit, which in turn generates from the electrical signal, a drive signal for the actuator.

Um Fehler bei E-Gas-Systemen bei der Übermittlung des Ansteuersignals von der Steuereinheit zum Antrieb der Drosselklappenwelle zu vermeiden gibt es Drosselklappenstutzen, bei denen die Steuereinheit für den Stellantrieb in das Gehäuse des Drosselklappenstutzens integriert ist. Die Steuereinheit kann dabei in eine in dem Gehäuse angeordnete Elektronik integriert sein. Die Elektronik ist dabei für weitere Funktionen des Drosselklappenstutzens vorgesehen, beispielsweise für die Ansteuerung einer Positionskontrolle der Drosselklappenwelle sowie die Erfassung und Speicherung von Daten des Drosselklappenstutzens. Eine Integration einer Elektronik in das Gehäuse des Drosselklappenstutzens ist häufig mit einem besonders großen Herstellungs- und Montageaufwand verbunden, da das Gehäuse zusätzlich eine Aufnahme für die Elektronik aufweisen muss. Außerdem ist zur Montage des Drosselklappenstutzens ein zusätzlicher Montageschritt erforderlich, bei dem die Elektronik in das Gehäuse des Drosselklappenstutzens integriert wird.To avoid errors in e-gas systems in the transmission of the drive signal from the control unit for driving the throttle shaft, there are throttle body, in which the control unit for the actuator is integrated in the housing of the throttle body. The control unit can be integrated in an electronics arranged in the housing. The electronics are provided for further functions of the throttle body, for example, for controlling a position control of the throttle shaft and the detection and storage of data of the throttle body. An integration of electronics in the housing of the throttle body is often associated with a particularly large manufacturing and assembly costs, since the housing must also have a receptacle for the electronics. In addition, an additional assembly step is required for mounting the throttle body, in which the electronics is integrated into the housing of the throttle body.

Selbst wenn durch die Integration der Elektronik für den Drosselklappenstutzen in das Gehäuse des Drosselklappenstutzens Übermittlungsfehler des Ansteuersignals des Stellantriebs für die Drosselklappe besonders zuverlässig vermieden sind kann es sich jedoch als problematisch erweisen, die Elektronik des Drosselklappenstutzens an die übrige Elektronik des Kraftfahrzeugs anzuschließen. Eine Verbindung der Elektronik des Drosselklappenstutzens mit der übrigen Elektronik des Kraftfahrzeugs ist erforderlich, um beispielsweise die Stellung der Drosselklappe mit dem Betrieb eines Zündungsgeräts und/oder eines Einspritzgerätes zu koordinieren. Diese Verbindung der Elektronik des Drosselklappenstutzens mit anderer Elektronik, insbesondere Steuerelektronik, des Kraftfahrzeugs bedingt einen besonders hohen Montageaufwand bei der Installation des Drosselklappenstutzens oder E-Gas-Systems in einem Kraftfahrzeug. Die von der anderen Elektronik des Kraftfahrzeugs angesteuerten weiteren elektrischen Geräte können dabei sowohl innerhalb als auch außerhalb des Verbrennungsmotors im Kraftfahrzeug angeordnet sein. Weiterhin können die zwischen der Elektronik des Drosselklappenstutzens und der anderen Elektronik auszutauschenden Signale aufgrund von Störimpulsen verfälscht werden, wobei es zu einer fehlerhaften und im Extremfall zu gar keiner Signalübertragung kommen kann. Weiterhin bedeutet jedes im Kraftfahrzeug zu verlegende Kabel einen zusätzlichen Montageaufwand.Even if the integration of the electronics for the throttle body in the housing of the throttle body transmission error of the drive signal of the actuator for the throttle are particularly reliable avoided, however, it may prove to be problematic to connect the electronics of the throttle body to the rest of the electronics of the motor vehicle. A connection of the electronics of the throttle body with the rest of the electronics of the motor vehicle is required to coordinate, for example, the position of the throttle with the operation of an ignition device and / or an injection device. This connection of the electronics of the throttle body with other electronics, in particular control electronics, of the motor vehicle requires a particularly high installation cost when installing the throttle body or e-gas system in a motor vehicle. The driven by the other electronics of the motor vehicle further electrical devices can be arranged both inside and outside the internal combustion engine in the motor vehicle. Furthermore, the signals to be exchanged between the electronics of the throttle body and the other electronics can be falsified due to glitches, which can lead to a faulty and in extreme cases to no signal transmission. Furthermore, each cable to be laid in the motor vehicle means an additional installation effort.

Aus der US 5 482 018 ist ein Motorsteuersystem für eine Brennkraftmaschine mit einem Drosselklappengehäuse bekannt, das ein Teilgehäuse aufweist, in dem eine elektronische Einheit zum Berechnen und Steuern der Drosselklappe angeordnet ist.From the US 5,482,018 For example, an engine control system for an internal combustion engine having a throttle body having a sub-housing in which an electronic unit for calculating and controlling the throttle is disposed is known.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Drosselklappenstutzen der oben genannten Art anzugeben, dessen Elektronik mit besonders geringem Herstellungs- und Montageaufwand in besonders einfacher Weise mit anderer Elektronik des Kraftfahrzeugs verbindbar ist. Bezüglich des Drosselklappenstutzens wird die Aufgabe erfindungsgemäß gelöst durch eine gemeinsame Anordnung der ersten Elektronik des Drosselklappenstutzens und einer zweiten Elektronik für eine Anzahl von außerhalb des Gehäuses angeordneten elektrischen Geräten in dem Gehäusedeckel des Drosselklappenstutzens, wobei sowohl die erste Elektronik des Drosselklappenstutzens als auch die zweite Elektronik der elektrischen Geräte über zumindest teilweise in dem Gehäusedeckel angeordnete elektrische Verbindungsmittel mit den außerhalb des Gehäuses angeordneten elektrischen Geräten kontaktierbar ist.The invention is therefore based on the object to provide a throttle body of the type mentioned above, whose electronics with particularly low manufacturing and assembly costs in a particularly simple manner with other electronics of the motor vehicle is connectable. With respect to the throttle body, the object is achieved by a common arrangement of the first electronics of the throttle body and a second electronics for a number of outside the housing arranged electrical devices in the housing cover of the throttle body, both the first electronics of the throttle body and the second electronics of the electrical equipment via at least partially disposed in the housing cover electrical connection means with the outside of the housing arranged electrical equipment is contacted.

Die Erfindung geht dabei von der Überlegung aus, daß ein mit besonders geringem Herstellungs- und Montageaufwand zu erstellender Drosselklappenstutzen dann besonders einfach mit anderer Elektronik des Kraftfahrzeugs verbindbar ist, wenn die elektrischen Verbindungsleitungen vom Drosselkläppenstutzen zu dieser anderen Elektronik besonders kurz ausgeführt sind. Da aber die Sensorik des Kraftfahrzeugs, insbesondere des Verbrennungsmotors, an bestimmten Orten im Kraftfahrzeug angeordnet sein muss, um beispielsweise spezifische Daten wie eine Öltemperatur und/oder einen Ölstand zu erfassen, kann die übrige Elektronik des Kraftfahrzeugs nicht zwingend in unmittelbarer Nähe des Drosselklappenstutzens angeordnet sein. Die Anordnung der übrigen Elektronik des Kraftfahrzeugs an anderen Orten als dem des Drosselklappenstutzens kann jedoch zu Fehlern bei der Signalübertragung führen. Eine Fehlübertragung der zu übertragenden Signale lässt sich besonders gut dadurch vermeiden, wenn eine zentrale Erfassungs-, Speicher, Auswerte-, Steuer- und/oder Regeleinheit vorgesehen ist. In dieser zentralen Einheit laufen dann alle erfassten Daten zusammen und werden so aufbereitet, daß die entsprechenden Steuersignale zuverlässig an die elektrischen Geräte übertragbar sind. Wird hierbei diese zentrale Einheit in eines der elektrischen Geräte oder in den Drosselklappenstutzen integriert, so lässt sich zumindest für die spezielle Einrichtung, in der die zentrale Einheit angeordnet ist, eine Fehlübertragung besonders gut vermeiden.The invention is based on the consideration that a particularly low production and assembly costs to create Drosselklappenstutzen is then particularly easily connected to other electronics of the motor vehicle, when the electrical connection lines from the throttle body to this other electronics are designed to be particularly short. However, since the sensor system of the motor vehicle, in particular of the internal combustion engine, must be arranged at certain locations in the motor vehicle in order to detect, for example, specific data such as an oil temperature and / or an oil level, the remaining electronics of the motor vehicle can not necessarily be arranged in the immediate vicinity of the throttle body , The arrangement of the rest of the electronics of the motor vehicle at locations other than that of the throttle body, however, can lead to errors in the signal transmission. A faulty transmission of the signals to be transmitted can be particularly well avoided if a central detection, memory, evaluation, control and / or regulating unit is provided. In this central unit then all collected data run together and are processed so that the corresponding control signals are reliably transferred to the electrical equipment. If in this case this central unit is integrated in one of the electrical devices or in the throttle body, Thus, at least for the special device in which the central unit is arranged, a faulty transmission can be avoided particularly well.

Da die für den Antrieb der Drosselklappe des Drosselklappenstutzens erforderliche Erfassungs-, Auswerte-, Regelund/oder Steuerelektronik bereits in den Drosselklappenstutzen integriert ist, könnte auch eine weitere zentrale Einheit, die mit weiteren elektrischen Geräten des Verbrennungsmotors kommuniziert, im Drosselklappenstutzen angeordnet werden. Dabei sollte jedoch aus Platzgründen der Drosselklappenstutzen nicht größere äußere Abmaße als bisher aufweisen. Zudem sollte der für den Drosselklappenstutzen erforderliche Herstellungs- und Montageaufwand ein besonders geringes Maß aufweisen. Hierzu ist sowohl die erste Elektronik für den elektrischen Antrieb als auch die zweite Elektronik für eine Anzahl von elektrischen Geräten des Kraftfahrzeugs unmittelbar in dem Gehäusedeckel des Gehäuses des. Drosselklappenstutzens angeordnet. Um hierbei gleichzeitig eine besonders einfache Kontaktierung der ersten und der zweiten Elektronik mit weiteren elektrischen Geräten des Kraftfahrzeugs sicherzustellen, sind sowohl die erste als auch die zweite Elektronik über in dem Gehäusedeckel angeordnete elektrische Verbindungsmittel mit außerhalb des Gehäuses des Drosselklappenstutzens angeordneten elektrischen Geräten kontaktierbar.Since the detection, evaluation, control and / or control electronics required for driving the throttle valve of the throttle body are already integrated in the throttle body, another central unit that communicates with other electrical equipment of the internal combustion engine could also be arranged in the throttle body. However, for reasons of space, the throttle body should not have larger outer dimensions than before. In addition, the required for the throttle body manufacturing and assembly costs should have a particularly low level. For this purpose, both the first electronics for the electric drive and the second electronics for a number of electrical devices of the motor vehicle are arranged directly in the housing cover of the housing of the throttle body. In order to ensure at the same time a particularly simple contacting of the first and the second electronics with other electrical devices of the motor vehicle, both the first and the second electronics can be contacted via arranged in the housing cover electrical connection means arranged outside the housing of the throttle body electrical equipment.

Vorteilhafterweise sind die elektrischen Geräte in einem Verbrennungsmotor eines Kraftfahrzeuges angeordnet. Ein Drosselklappenstutzen ist ein herkömmliches Bauteil für ein Kraftfahrzeug, das häufig außerhalb des Verbrennungsmotors angeordnet ist. Genau wie der Drosselklappenstutzen brauchen auch die weiteren elektrischen Geräte des Verbrennungsmotors des Kraftfahrzeugs eine zentrale Einheit, über die Daten von elektrischen Geräten des Verbrennungsmotors einlesbar sind und über die Steuersignale an die elektrischen Geräte des Verbrennungsmotors ausgebbar sind. Eine gemeinsame Anordnung sowohl der ersten Elektronik für Drosselklappenstutzen als auch der zweiten Elektronik für andere elektrischen Geräte zentral im Gehäusedeckel des Drosselklappenstutzens gewährleistet eine Kompaktbauweise der Elektronik des Kraftfahrzeugs, wodurch die Herstellungs- und Montagekosten für die Elektronik des betreffenden Kraftfahrzeugs besonders gering ausfallen.Advantageously, the electrical devices are arranged in an internal combustion engine of a motor vehicle. A throttle body is a conventional component for a motor vehicle that is often located outside of the engine. Just like the throttle body, the other electrical devices of the internal combustion engine of the motor vehicle need a central unit via which data from electrical devices of the internal combustion engine can be read and the control signals to the electrical Devices of the internal combustion engine can be output. A common arrangement of both the first electronics for throttle body as well as the second electronics for other electrical equipment centrally in the housing cover of the throttle body ensures a compact design of the electronics of the motor vehicle, whereby the manufacturing and assembly costs for the electronics of the relevant motor vehicle are particularly low.

Vorteilhafterweise umfasst die Elektronik für die außerhalb des Gehäuses des Drosselklappenstutzens angeordneten elektrischen Geräte eine Steuereinheit, ein Datenerfassungseinheit und eine Datenspeichereinheit. Diese drei Einheiten gewährleisten besonders zuverlässig in besonders einfacher Weise eine Erfassung und Speicherung von Daten der elektrischen Geräte, wobei mittels erfasster oder gespeicherter Daten eine Ansteuerung eines oder mehrerer elektrischer Geräte erfolgen kann.Advantageously, the electronics for the electrical equipment located outside the housing of the throttle body comprise a control unit, a data acquisition unit and a data storage unit. These three units are particularly reliable in a particularly simple manner, a detection and storage of data of the electrical equipment, which can be done by means of detected or stored data driving one or more electrical devices.

Die elektrischen Geräte sind vorteilhafterweise ein Zündungsgerät und/oder ein Einspritzgerät und/oder ein Ölstandsmessgerät und/oder ein Luftmassenreguliergerät. Zusätzlich oder alternativ können die elektrischen Geräte auch Motorsteuerungselektroniken und/oder ein elektromechanisch integrierter Drosselklappenstutzen sein. Diese elektrischen Geräte steuern unmittelbar die Verbrennung des Kraftstoffs im Verbrennungsmotor und stehen daher in einem unmittelbaren Wirkzusammenhang mit der Stellung der Drosselklappe in der Drosselöffnung des Drosselklappenstutzens. Daher sollte besonders bei den genannten elektrischen Geräten die Auslese-, Steuer- und/oder Regelelektronik im Drosselklappenstutzen gemeinsam mit der Elektronik für den Drosselklappenstutzen angeordnet sein.The electrical devices are advantageously an ignition device and / or an injection device and / or an oil level gauge and / or a Luftmassenreguliergerät. Additionally or alternatively, the electrical devices may also be engine control electronics and / or an electromechanically integrated throttle body. These electrical devices directly control the combustion of the fuel in the internal combustion engine and therefore are in direct operative connection with the position of the throttle in the throttle opening of the throttle body. Therefore, the reading, control and / or control electronics in the throttle body should be arranged together with the electronics for the throttle body, especially in the aforementioned electrical equipment.

Vorteilhafterweise besteht der Gehäusedeckel aus Kunststoff, wobei die elektrischen Verbindungsmittel zumindest teilweise in den Kunststoff eingebettet sind. Eine Integration der elektrischen Verbindungsmittel in den Kunststoff vermindert weiterhin den Montageaufwand des Drosselklappenstutzens, da die in den Gehäusedeckel integrierten elektrischen Verbindungsmittel nur noch mit der ersten und/oder zweiten Elektronik des Gehäusedeckels zu verbinden sind. Die elektrischen Verbindungsmittel können beispielsweise durch Einspritzen in den Kunststoff während der Herstellung des Gehäusedeckels im Spritzgussverfahren in den Gehäusedeckeln integriert werden. Alternativ kann der Gehäusedekkel jedoch auch aus einem metallhaltigen Kunststoff oder aber auch vollständig aus Metall gefertigt sein. Bei einer Fertigung des Gehäusedeckels aus Metall, beispielsweise Aluminium, müssen jedoch die elektrischen Verbindungsmittel in den Gehäusedeckel nachträglich eingelegt und zusätzlich isoliert werden, um einen elektrischen Kurzschluss zum Gehäusedeckel zu vermeiden. Hiermit ist ein zusätzlicher Montageaufwand verbunden, was sich als unwirtschaftlich bei der Produktion des Drosselklappenstutzens erweist.Advantageously, the housing cover made of plastic, wherein the electrical connection means at least partially embedded in the plastic. An integration of the electrical connection means in the plastic further reduces the assembly costs of the throttle body, since the integrated in the housing cover electrical connection means are only to be connected to the first and / or second electronics of the housing cover. The electrical connection means can be integrated, for example, by injection into the plastic during the manufacture of the housing cover by injection molding in the housing covers. Alternatively, the Gehäusedekkel can also be made of a metal-containing plastic or completely made of metal. In a production of the housing cover made of metal, such as aluminum, however, the electrical connection means must be subsequently inserted into the housing cover and additionally insulated in order to avoid an electrical short circuit to the housing cover. This is an additional installation effort associated, which proves to be uneconomical in the production of the throttle body.

Sowohl die erste Elektronik für den Drosselklappenstutzen als auch die zweite Elektronik für die außerhalb des Gehäuses angeordneten elektrischen Geräte ist vorteilhafterweise in einem Bereich des Gehäusedeckels angeordnet, der von einem Abdeckelement begrenzt ist. Dieses Abdeckelement kann dabei aus Metall, Kunststoff oder Keramik gefertigt sein. Das Abdeckelement trennt besonders zuverlässig die erste Elektronik und die zweite Elektronik von dem übrigen Innenbereich des Gehäuses des Drosselklappenstutzens. Diese Trennung verhindert besonders zuverlässig ein Eindringen von Fremdpartikeln aus dem übrigen Innenbereich des Gehäuses des Drosselklappenstutzens in die erste Elektronik und in die zweite Elektronik.Both the first electronics for the throttle body and the second electronics for the outside of the housing arranged electrical equipment is advantageously arranged in a region of the housing cover, which is bounded by a cover. This cover can be made of metal, plastic or ceramic. The cover separates particularly reliable the first electronics and the second electronics from the remaining interior of the housing of the throttle body. This separation prevents particularly reliable penetration of foreign particles from the remaining interior of the housing of the throttle body in the first electronics and in the second electronics.

Vorteilhafterweise sind die erste Elektronik für den Drosselklappenstutzen und die zweite Elektronik für die außerhalb des Gehäuses des Drosselklappenstutzens angeordneten elektrischen Geräte auf einer gemeinsamen Leiterplatte in dem Gehäusedeckel des Gehäuses des Drosselklappenstutzens angeordnet. Die gemeinsame Anordnung der ersten Elektronik und der zweiten Elektronik auf einer gemeinsamen Leiterplatte bedingt einen besonders geringen Herstellungsaufwand sowohl für die erste Elektronik als auch für die zweite Elektronik, da diese gemeinsam in einem Herstellungsverfahren auf eine Leiterplatte gebracht werden können. Zudem vereinfacht sich der Montageaufwand des Drosselklappenstutzens, da lediglich eine einzige Leiterplatine in den Gehäusedeckel des Gehäuses des Drosselklappenstutzens einzusetzen ist.Advantageously, the first electronics for the throttle body and the second electronics for the outside arranged the housing of the throttle body arranged electrical equipment on a common circuit board in the housing cover of the housing of the throttle body. The common arrangement of the first electronics and the second electronics on a common circuit board requires a particularly low production cost for both the first electronics and the second electronics, since these can be brought together in a manufacturing process on a circuit board. In addition, the assembly effort of the throttle body simplifies, since only a single circuit board is to be inserted into the housing cover of the housing of the throttle body.

Die Leiterplatte ist vorteilhafterweise auf einer wärmeleitenden Platte, insbesondere einer metallischen Platte, angeordnet. Die Anordnung der Leiterplatte auf einer wärmeleitenden Platte stellt besonders zuverlässig sicher, dass beim Betrieb des Drosselklappenstutzens entstehende Wärme der Elektronik über die besonders große Fläche der wärmeleitenden Platte zuverlässig aus dem Gehäuse des Drosselklappenstutzens abzuführen ist. Hierdurch ist bei geeigneter Auslegung der wärmeleitenden Platte ein übermäßiges Erhitzen der Elektronik zuverlässig verhindert. Ein übermäßiges Erhitzen der Elektronik sollte vermeidbar sein, um Schäden an der Elektronik oder im Extremfall einen vollständigen Ausfall der Elektronik zuverlässig zu verhindern. Da in der Regel aus Kostengründen der Gehäusedeckel des Gehäuses des Drosselklappenstutzens aus Kunststoff und nicht aus Metall gefertigt ist, kann dieser üblicherweise keine Wärme abführen. Durch die wärmeleitende Platte ist in einfacher Weise sichergestellt, dass die durch die Elektronik entstehende Wärme beim Betrieb des Drosselklappenstutzens aus dem Bereich der Elektronik abführbar ist.The printed circuit board is advantageously arranged on a heat-conducting plate, in particular a metallic plate. The arrangement of the printed circuit board on a thermally conductive plate ensures particularly reliable, that is reliably dissipate during operation of the throttle body heat of the electronics on the particularly large area of the heat-conducting plate reliably from the housing of the throttle body. As a result, with a suitable design of the heat-conducting plate, excessive heating of the electronics is reliably prevented. Excessive heating of the electronics should be avoidable in order to reliably prevent damage to the electronics or, in extreme cases, complete failure of the electronics. Since usually the housing cover of the housing of the throttle body is made of plastic and not made of metal for cost reasons, this can usually dissipate no heat. The heat-conducting plate ensures in a simple manner that the heat generated by the electronics during operation of the throttle body can be removed from the field of electronics.

Vorteilhafterweise ist die wärmeleitende Platte, insbesondere metallische Platte, mit Mitteln zum Befestigen sowohl an dem Gehäusedeckel als auch an dem Gehäusekörper befestigt. Eine Befestigung der wärmeleitenden Platte erfolgt dabei vorteilhafterweise mit Schrauben, die überwiegend aus Metall bestehen. Über die Schrauben ist dann die Wärme der wärmeleitenden Platte an den Gehäusekörper übertragbar, der damit eine Wärmesenke darstellt. Hierdurch ist besonders zuverlässig ein Überhitzen der in dem Gehäusedeckel des Drosselklappenstutzens angeordneten Elektronik vermieden.Advantageously, the heat-conducting plate, in particular metallic plate, is fastened with means for fastening both to the housing cover and to the housing body. An attachment of the heat-conducting plate is advantageously carried out with screws, which consist predominantly of metal. About the screws then the heat of the heat-conducting plate is transferable to the housing body, which thus represents a heat sink. As a result, overheating of the electronics arranged in the housing cover of the throttle body is particularly reliably avoided.

Vorteilhafterweise besteht der Gehäusekörper überwiegend aus Metall, insbesondere Aluminium. Ein aus Metall gefertigter Gehäusekörper leitet besonders gut die auf ihn mittels der Schrauben übertragene Wärme nach außen ab, wodurch eine Überhitzung der Elektronik zusätzlich besonders sicher vermieden ist. Aluminium bietet dabei den Vorteil, daß es besonders einfach im Spritzgussverfahren zu verarbeiten ist.Advantageously, the housing body consists predominantly of metal, in particular aluminum. A made of metal housing body derives particularly good on him transferred by means of the screws heat to the outside, whereby an overheating of the electronics is additionally particularly safe avoided. Aluminum offers the advantage that it is particularly easy to process by injection molding.

Vorteilhafterweise ist der elektrische Stellantrieb der Drosselklappenwelle über eine elektrische Steckverbindung mit der ersten Elektronik des Drosselklappenstutzens verbunden. Mittels einer elektrischen Steckverbindung ist der elektrische Stellantrieb besonders einfach mit der Elektronik kontaktierbar. Hierdurch weist Montageaufwand für die Verbindung der ersten Elektronik mit dem elektrischen Stellantrieb ein besonders geringes Maß auf.Advantageously, the electric actuator of the throttle valve shaft is connected via an electrical plug connection with the first electronics of the throttle body. By means of an electrical plug connection, the electric actuator is particularly easy to contact with the electronics. As a result, installation costs for the connection of the first electronics with the electric actuator on a particularly low level.

Vorteilhafterweise ist in dem Gehäuse eine Rückstellfedereinrichtung zum Zurückstellen der Drosselklappe in eine Ausgangsstellung angeordnet. Diese Rückstellfedereinrichtung stellt bei einem Ausfall des elektrischen Stellantriebs der Drosselklappenwelle sicher, dass die Drosselklappe auch ohne den elektrischen Stellantrieb in eine Ausgangsstellung zurückstellbar ist. Dabei ist diese AusgangsStellung häufig nicht die Schließstellung der Drosselklappe sondern eine Stellung mit einem geringen Öffnungswinkel der Drosselklappe um sicherzustellen, dass der Fahrer des Kraftfahrzeugs auch bei einem Ausfall des elektrischen Stellantriebs der Drosselklappenwelle eine Reparaturwerkstatt noch erreichen kann.Advantageously, a return spring means for returning the throttle valve is arranged in an initial position in the housing. This return spring device ensures in case of failure of the electric actuator of the throttle shaft, that the throttle is reset even without the electric actuator in an initial position. This is the starting position often not the closed position of the throttle but a position with a small opening angle of the throttle to ensure that the driver of the motor vehicle can still reach a repair shop even in case of failure of the electric actuator of the throttle shaft.

Vorteilhafterweise ist in dem Gehäuse eine Einrichtung zur Erfassung der Position der Drosselklappenwelle angeordnet. Diese Einrichtung zur Erfassung der Position der Drosselklappenwelle stellt sicher, dass bei entsprechender Ansteuerung des elektrischen Antriebs der Drosselklappenwelle diese auch in eine wohl definierte position gebracht wird. Ergibt ein Signal der Einrichtung zur Erfassung der Position der Drosselklappenwelle dass diese trotz ordnungsgemäßer elektrischer Ansteuerung nicht die gewünschte Position einnimmt, so wird ein Fehlersignal produziert, das dem Fahrer des Kraftfahrzeugs signalisiert, dass die Funktion des Fahrpedals nicht ordnungsgemäß erfolgt.Advantageously, a device for detecting the position of the throttle shaft is arranged in the housing. This means for detecting the position of the throttle shaft ensures that with appropriate control of the electric drive of the throttle shaft, this is also brought into a well-defined position. If a signal from the device for detecting the position of the throttle valve shaft that despite proper electrical control does not assume the desired position, so an error signal is produced, which signals the driver of the motor vehicle that the function of the accelerator pedal is not done properly.

Ein Elektronikmodul mit Elektronik für ein Kraftfahrzeug und mit einem von einem Deckelelement verschließbaren Basiselement kann vorhanden sein, wobei das Kraftfahrzeug eine Vielzahl von elektrischen Geräten und den Drosselklappenstutzen aufweist und der Drosselklappenstutzen ein Gehäuse mit einer durchgehenden Drosselöffnung für eine auf einer Drosselklappenwelle schwenkbar angeordnete Drosselklappe und einen in dem Gehäuse angeordneten elektrischen Stellantrieb umfass wobei in dem Deckelelement die erste Elektronik für den Drosselklappenstutzen und die zweite Elektronik für die elektrischen Geräte des Kraftfahrzeugs ein einziges Modul bildend angeordnet ist, wobei zwischen der ersten Elektronik und der zweiten Elektronik Kopplungssignale übertragbar sind, wobei die erste Elektronik des Drosselklappenstutzens und die zweite Elektronik der elektrischen Geräte über elektrische Verbindungsmittel mit dem Drosselklappenstutzen und den elektrischen Geräten des Verbrennungsmotors verbindbar sind, und wobei die elektrischen Verbindungsmittel zumindest teilweise in dem Deckelelement angeordnet sind.An electronics module with electronics for a motor vehicle and with a closable by a cover element base element may be present, wherein the motor vehicle has a plurality of electrical devices and the throttle body and the throttle body a housing with a continuous throttle opening for a throttle valve shaft pivotally mounted throttle and a arranged in the housing electric actuator comprehensive wherein in the cover element, the first electronics for the throttle body and the second electronics for the electrical equipment of the motor vehicle is a single module forming, wherein between the first electronics and the second electronics coupling signals are transferable, wherein the first Electronics of the throttle body and the second electronics of the electrical equipment via electrical connection means with the throttle body and the electrical devices of the internal combustion engine are connectable, and wherein the electrical connection means are at least partially disposed in the cover element.

Die Erfindung geht dabei von der Überlegung aus, dass die Elektronik für ein Kraftfahrzeug aufteilbar ist in die Elektronik des Drosselklappenstutzens und in eine zweite Elektronik für die sonstigen elektrischen Geräte des Kraftfahrzeugs. Um Übertragungsfehler von Kopplungssignalen zwischen der ersten Elektronik des Drosselklappenstutzens und der zweiten Elektronik der anderen elektrischen Geräte des Kraftfahrzeugs zuverlässig zu vermeiden, sollte die erste Elektronik für den Drosselklappenstutzen und die zweite Elektronik für die Vielzahl von elektrischen Geräten des Kraftfahrzeugs nah beieinander angeordnet werden. Die erste Elektronik und die zweite Elektronik lassen sich dann besonders nah beieinander anordnen, wenn sie in einem gemeinsamen Elektronikmodul vereinigt sind. Hierbei erweist sich die Montage des Elektronikmoduls als besonders einfach, da lediglich ein einziges Modul im Kraftfahrzeug zu montieren ist statt einer ersten Elektronik für den Drosselklappenstutzen und einer zweiten Elektronik für die Vielzahl von elektrischen Geräten des Kraftfahrzeugs. Zudem bietet ein Elektronikmodul, das die erste Elektronik für den Drosselklappenstutzen mit der zweiten Elektronik der anderen elektrischen Geräte des Kraftfahrzeugs vereinigt den Vorteil, dass dieses Elektronikmodul irgendwo im Kraftfahrzeug angeordnet werden kann, und somit das Elektronikmodul auch in sogenannten toten Winkeln montiert werden kann.The invention is based on the consideration that the electronics for a motor vehicle can be divided into the electronics of the throttle body and in a second electronics for the other electrical equipment of the motor vehicle. In order to reliably avoid transmission errors of coupling signals between the first electronics of the throttle body and the second electronics of the other electrical devices of the motor vehicle, the first electronics for the throttle body and the second electronics for the plurality of electrical devices of the motor vehicle should be arranged close to each other. The first electronics and the second electronics can then be arranged particularly close to each other if they are combined in a common electronic module. In this case, the assembly of the electronic module proves to be particularly simple, since only a single module is to be mounted in the motor vehicle instead of a first electronics for the throttle body and a second electronics for the plurality of electrical devices of the motor vehicle. In addition, an electronic module that combines the first electronics for the throttle body with the second electronics of the other electrical equipment of the motor vehicle has the advantage that this electronic module can be located anywhere in the vehicle, and thus the electronics module can be mounted in so-called blind spots.

Vorteilhafterweise sind die elektrischen Geräte ein Zündungsgerät und/oder ein Einspritzgerät und/oder ein Ölstandsmessgerät und/oder ein Luftmassenreguliergerät. Diese elektrischen Geräte stehen in einem Wirkzusammenhang mit der Stellung der Drosselklappe im Drosselklappenstutzen und sollten daher zur Vermeidung von Übertragungsfehlern eine Elektronik aufweisen, die in unmittelbarer Nähe der ersten Elektronik des Drosselklappenstutzens angeordnet ist.Advantageously, the electrical devices are an ignition device and / or an injection device and / or an oil level gauge and / or a Luftmassenreguliergerät. These electrical devices are in an operative relationship with the position of the throttle in the throttle body and should therefore have to avoid transmission errors electronics that is located in the immediate vicinity of the first electronics of the throttle body.

Vorteilhafterweise ist der Gehäusedeckel aus Kunststoff hergestellt, wobei die elektrischen Verbindungsmittel zumindest teilweise in den Kunststoff eingebettet sind. Wird beispielsweise der Gehäusedeckel im Spritzgussverfahren aus Kunststoff hergestellt, so lassen sich die elektrischen Verbindungsmittel schon beim Spritzgussvorgang in den Kunststoff einbetten. Dadurch weist der Deckelelement einen besonders geringen Herstellungsaufwand auf.Advantageously, the housing cover is made of plastic, wherein the electrical connection means are at least partially embedded in the plastic. For example, if the housing cover made by injection molding of plastic, so can the electrical Embed connecting means already in the injection molding process in the plastic. As a result, the cover element has a particularly low production cost.

Die erste Elektronik für den Drosselklappenstutzen und die zweite Elektronik für die elektrischen Geräte des Verbrennungsmotors sind vorteilhafterweise auf einer gemeinsamen Leiterplatte in dem Deckelelement angeordnet. Eine gemeinsame Leiterplatte für die erste Elektronik des Drosselklappenstutzens und die zweite Elektronik der elektrischen Geräte des Kraftfahrzeugs ermöglicht, dass die erste Elektronik und die zweite Elektronik in einem einzigen Herstellungsschritt auf die Leiterplatte aufbringbar sind, wodurch mit der Erstellung der Leiterplatte ein besonders geringer Aufwand verbunden ist.The first electronics for the throttle body and the second electronics for the electrical equipment of the internal combustion engine are advantageously arranged on a common printed circuit board in the cover element. A common circuit board for the first electronics of the throttle body and the second electronics of the electrical equipment of the motor vehicle allows the first electronics and the second electronics can be applied to the circuit board in a single manufacturing step, which is associated with the creation of the circuit board, a particularly low cost ,

Vorteilhafterweise ist die Leiterplatte auf einer wärmeleitenden Platte, insbesondere einer metallischen Platte angeordnet. Als Metall eignet sich aufgrund der leichten Bearbeitbarkeit Aluminium. Da aus Kostengründen der Gehäusedekkel in der Regel aus Kunststoff gefertigt sein wird, ist mittels der wärmeleitenden Platten sichergestellt, dass die beim Betrieb des Drosselklappenstutzens entstehende Wärme besonders gut über die wärmeleitende Platte von der Elektronik wegtransportiert wird.Advantageously, the printed circuit board is arranged on a heat-conducting plate, in particular a metallic plate. As a metal is suitable because of the ease of machining aluminum. Since cost reasons, the Gehäusedekkel will usually be made of plastic, it is ensured by means of the heat-conducting plates that the heat generated during operation of the throttle body is transported away particularly well on the heat-conducting plate of the electronics.

Vorteilhafterweise ist die wärmeleitende Platte, insbesondere metallische Platte, mit Mitteln zum Befestigen sowohl an dem Deckelelement als auch an dem Basiselement befestigt. Dabei sind vorteilhafterweise die Mittel zum Befestigen Schrauben, die überwiegend aus Metall bestehen. Über die Schrauben ist eine Wärmebrücke zum Basiselement herstellbar, über das Betrieb der Elektronik entstehende Wärme besonders einfach ableitbar ist.Advantageously, the heat-conducting plate, in particular metallic plate, is fastened with means for fastening both to the cover element and to the base element. In this case, advantageously, the means for fastening screws, which consist predominantly of metal. About the screws a thermal bridge to the base element can be produced, on the operation of the electronics resulting heat is particularly easy derivable.

Vorteilhafterweise besteht das Basiselement überwiegend aus Metall, insbesondere aus Aluminium. Das Basiselement leitet dann besonders zuverlässig die durch die Schrauben auf das Basiselement übertragene Wärme der ersten Elektronik und der zweiten Elektronik an die Umgebung ab, wodurch ein übermäßiges. Erhitzen der auf der Leiterplatte angeordneten ersten Elektronik und der zweiten Elektronik besonders zuverlässig vermieden ist.Advantageously, the base element consists predominantly of metal, in particular of aluminum. The base element passes then particularly reliable the transmitted by the screws on the base element heat of the first electronics and the second electronics to the environment, creating an excessive. Heating the arranged on the circuit board first electronics and the second electronics is particularly reliably avoided.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass durch die Integration der für das Kraftfahrzeug erforderlichen Elektronik und der Elektronik für den Drosselklappenstutzen in eine einzige gemeinsame Leiterplatine und die Anordnung wiederum dieser Leiterplatine in dem Gehäusedeckel des Drosselklappenstutzens oder in dem Elektronikmodul ein zentrales Element geschaffen wird, dass das Herzstück der Elektronik des Kraftfahrzeugs darstellt. Durch dieses zentrale Element, das entweder im Gehäuse des Drosselklappenstutzens oder aber als Elektronikmodul irgendwo im Kraftfahrzeug angeordnet werden kann, ist in besonders einfacher Weise die gesamte Elektronik des Kraftfahrzeugs mittels eines einzigen Montageschritts im Kraftfahrzeug anzuordnen. Besondere Flexibilität der Anordnung ergibt sich dabei insbesondere, wenn das Elektronikmodul Anwendung findet. Auch bei einem Defekt des zentralen Elements ist lediglich eine einzige Leiterplatte auf Defekte hin zu untersuchen und kann bei Bedarf auch durch Austausch wieder in einen funktionstüchtigen Zustand überführt werden.The advantages achieved by the invention are in particular that created by the integration of the electronics required for the motor vehicle and the electronics for the throttle body in a single common printed circuit board and the arrangement turn this printed circuit board in the housing cover of the throttle body or in the electronic module, a central element is that represents the heart of the electronics of the motor vehicle. By this central element, which can be located either in the housing of the throttle body or as an electronics module somewhere in the vehicle, the entire electronics of the motor vehicle by means of a single assembly step in the vehicle is to be arranged in a particularly simple manner. Particular flexibility of the arrangement results in particular when the electronic module is used. Even in the case of a defect of the central element, only a single printed circuit board is to be examined for defects and, if necessary, can also be replaced by replacement to a functional state.

Ein Ausführungsbeispiel der Erfindung wird anhand einer Zeichnung näher erläutert. Darin zeigen:

  • Fig. 2 den Gehäusedeckel und Elektronik sowie eine Steckverbindung,
  • Fig. 3 ein Elektronikmodul.
An embodiment of the invention will be explained in more detail with reference to a drawing. Show:
  • 1 a throttle body,
  • 2 shows the housing cover and electronics and a plug connection,

Der Drosselklappenstutzen 10 gemäß Figur 1 dient dazu, einem nicht dargestellten Verbraucher, beispielsweise einer Einspritzeinrichtung eines ebenfalls nicht dargestellten Kraftfahrzeugs, ein Luft- oder ein Kraftstoff-Luft-Gemisch zuzuführen wobei mittels des Drosselklappenstutzens 10 die dem Verbraucher zuzuführende Frischgasmenge steuerbar ist. Hierzu weist der Drosselklappenstutzen 10 ein Gehäuse 12 auf, das überwiegend aus Aluminium 14 gefertigt ist. Alternativ kann das Gehäuse jedoch auch aus Kunststoff gefertigt sein. Das Gehäuse 12 umfaßt einen Gehäusekörper 15, in dem eine durchgehende Drosselöffnung 16 angeordnet ist, über die dem nicht dargestellten Verbraucher Luft- bzw. ein Kraftstoff-Luft-Gemisch zuführbar ist. Zur Einstellung des zuzuführenden Volumens des Frischgases ist auf einer Drosselklappenwelle 18 mit Hilfe von Befestigungsmitteln 20 eine Drosselklappe 22 angeordnet. Die Drosselklappenwelle 18, die Befestigungsmittel 20 sowie die Drosselklappe 22 sind Figur 1 in explosiver Darstellung zu entnehmen.The throttle body 10 according to Figure 1 is used to supply a consumer, not shown, for example, an injection device of a motor vehicle, also not shown, an air or a fuel-air mixture by means of the throttle body 10, the consumer supplied fresh gas quantity is controllable. For this purpose, the throttle body 10 has a housing 12, which is made predominantly of aluminum 14. Alternatively, however, the housing may also be made of plastic. The housing 12 comprises a housing body 15, in which a continuous throttle opening 16 is arranged, via which the consumer, not shown, air or a fuel-air mixture can be fed. To set the volume of fresh gas to be supplied, a throttle valve 22 is arranged on a throttle valve shaft 18 by means of fastening means 20. The throttle valve shaft 18, the fastening means 20 and the throttle valve 22 are shown in Figure 1 in an explosive representation.

Eine Drehung der Drosselklappenwelle 18 bewirkt gleichzeitig eine Verschwenkung der auf der Drosselklappenwelle 18 angeordneten Drosselklappe 22. Ein Verschwenken der Drosselklappe 22 bewirkt eine Vergrößerung oder Verkleinerung der Öffnung der Drosselöffnung 16. Hierdurch ist die Menge des durch die Drosselöffnung 16 hindurchtretenden Strömungsmediums einstellbar. Mittels einer Bewegung der Drosselklappe 22 erfolgt somit eine Regulierung des Durchsatzes des Luft- bzw. Kraftstoff-Luft-Gemischs durch die Drosselöffnung 16 des Drosselklappenstutzens 10.A rotation of the throttle shaft 18 simultaneously causes a pivoting of the arranged on the throttle shaft 18 throttle valve 22. A pivoting of the throttle valve 22 causes an enlargement or reduction of the opening of the throttle opening 16. Thus, the amount of passing through the throttle opening 16 flow medium is adjustable. By means of a movement of the throttle valve 22 is thus a regulation of the flow rate of the air or fuel-air mixture through the throttle opening 16 of the throttle body 10th

Die Drosselklappenwelle 18 kann mit einer nicht näher dargestellten Seilscheibe verbunden sein, die wiederum über einen Bowdenzug mit einer Einstellvorrichtung für eine Leistungsanforderung verbunden ist. Die Einstellvorrichtung kann hierbei als Gaspedal eines Kraftfahrzeuges ausgebildet sein, so dass eine Betätigung dieser Einstellvorrichtung durch den Fahrer des Kraftfahrzeugs die Drosselklappe 22 von einer Stellung minimaler Öffnung, insbesondere einer Schließstellung, bis in eine Stellung maximaler Öffnung, insbesondere eine Offenstellung, gebracht werden kann, um hierdurch die Leistungsabgabe des Kraftfahrzeugs zu steuern.The throttle shaft 18 may be connected to a pulley, not shown, which in turn is connected via a Bowden cable with a setting device for a power request. The adjusting device can be designed as an accelerator pedal of a motor vehicle, so that an actuation of this adjustment can be brought by the driver of the motor vehicle, the throttle valve 22 from a position of minimum opening, in particular a closed position, to a position of maximum opening, in particular an open position, to thereby control the power output of the motor vehicle.

Die in Figur 1 gezeigte Drosselklappenwelle 18 des Drosselklappenstutzens 10 ist im Gegensatz dazu entweder in einem Teilbereich von einem Stellantrieb und ansonsten über das Gaspedal einstellbar oder aber die Drosselklappe 22 ist über den gesamten Verstellbereich von einem Stellantrieb einstellbar. Bei diesen sogenannten E-Gas oder drive-bywire-Systemen wird die mechanische Leistungssteuerung, beispielsweise Niederdrücken eines Gaspedals, in ein elektrisches Signal umgesetzt. Dieses Signal wird wiederum einer Steuereinheit zugeführt, die ein Ansteuersignal für den Stellantrieb erzeugt. Es gibt bei diesen Systemen im Normalbetrieb keine mechanische Kopplung zwischen dem Gaspedal und der Drosselklappe 22.The throttle shaft 18 of the throttle body 10 shown in Figure 1 is in contrast either in a portion of an actuator and otherwise adjustable via the accelerator pedal or the throttle valve 22 is adjustable over the entire adjustment of an actuator. In these so-called E-gas or drive-by-wire systems, the mechanical power control, such as depressing an accelerator pedal, converted into an electrical signal. This signal is in turn supplied to a control unit which generates a drive signal for the actuator. There is no mechanical coupling between the accelerator pedal and the throttle 22 in these systems in normal operation.

Zur Verstellung der Drosselklappenwelle 18 und damit der Drosselklappe 22 weist daher der Drosselklappenstutzen 10 ein Antriebsgehäuse 24 auf. Das Antriebsgehäuse 24 ist einstückig mit dem Gehäuse 12 des Drosselklappenstutzens 10 ausgeführt. Das Gehäuse 12 des Drosselklappenstutzens 10 und das Antriebsgehäuse 24 können alternativ auch zweistükkig ausgeführt sein. In dem Antriebsgehäuse 24 ist ein als Elektromotor ausgebildeter elektrischer Stellantrieb 26 angeordnet. Der als Elektromotor ausgebildete elektrische Stellantrieb 26 ist über ein Getriebe 28 mit der Drosselklappenwelle 18 verbunden. Die Drosselklappenwelle 18 ist also von dem als Elektromotor ausgebildeten Stellantrieb 26 verschwenkbar.For adjusting the throttle shaft 18 and thus the throttle valve 22, therefore, the throttle body 10 has a drive housing 24. The drive housing 24 is designed in one piece with the housing 12 of the throttle body 10. The housing 12 of the throttle body 10 and the drive housing 24 may alternatively be designed zweistükkig. In the drive housing 24 designed as an electric motor electric actuator 26 is arranged. The trained as an electric motor electric actuator 26 is connected via a gear 28 to the throttle valve shaft 18. The throttle valve shaft 18 is thus pivotable from the actuator 26 designed as an electric motor.

Der Bereich des Gehäuses 12, in dem der als Elektromotor ausgebildete Stellantrieb 26 und das Getriebe 28 angeordnet sind, ist von einem Gehäusedeckel 40 verschließbar. Der Gehäusedeckel 40 ist aus Kunststoff 42 gefertigt. Alternativ kann der Gehäusedeckel 40 jedoch auch aus Metall, insbesondere Aluminium, gefertigt sein. Der Gehäusedeckel 40 ist im Spritzgussverfahren aus Kunststoff 42 hergestellt. Dabei sind elektrische Verbindungsmittel 44 in die für den Gehäusedeckel 40 vorgesehene Spritzgußform eingelegt worden, die während des Spritzgussverfahrens zumindest teilweise in den Kunststoff 42 eingebettet worden sind. Über die elektrischen Verbindungsmittel 44 ist der Drosselklappenstutzen 10 mit elektrischen Geräten 46 verbindbar, die außerhalb des Drosselklappenstutzens 10 angeordnet sind. Die elektrischen Geräte, die schematisch in Figur 1 angedeutet sind, sind gemäß diesem Ausführungsbeispiel ein Zündungsgerät 48, ein Einspritzgerät 50, ein Ölstandsmessgerät 52 und ein Luftmassenreguliergerät 54. Die elektrischen Geräte 46 sind ebenso wie der Drosselklappenstutzen 10 in dem Verbrennungsmotor des Kraftfahrzeugs angeordnet, wobei in der Zeichnung weder der Verbrennungsmotor noch das Kraftfahrzeug näher dargestellt sind.The region of the housing 12, in which the actuator 26 designed as an electric motor and the transmission 28 are arranged, can be closed by a housing cover 40. The housing cover 40 is made of plastic 42. Alternatively, however, the housing cover 40 may also be made of metal, in particular aluminum. The housing cover 40 is made by injection molding of plastic 42. In this case, electrical connection means 44 have been inserted into the intended for the housing cover 40 injection mold, which have been at least partially embedded in the plastic 42 during the injection molding process. About the electrical connection means 44 of the throttle body 10 is connected to electrical equipment 46, which are arranged outside of the throttle body 10. The electrical devices, which are schematically indicated in Figure 1, according to this embodiment, an ignition device 48, an injection device 50, an oil level gauge 52 and a Luftmassenreguliergerät 54. The electrical equipment 46 are arranged as well as the throttle body 10 in the internal combustion engine of the motor vehicle in the drawing, neither the internal combustion engine nor the motor vehicle are shown in detail.

Die elektrischen Verbindungsmittel 44 des Gehäusedeckels 40 sind über eine Platine 56 und eine elektrische Steckverbindung 58 mit dem elektrischen Antrieb 26 verbunden. Hierbei ist zur Verbindung der elektrischen Verbindungsmittel 44 des Gehäusedeckels 40 mit der Platine 56 eine elektrische Kontaktplatte 60 vorgesehen, die zwischen dem Gehäusedeckel 40 und der Platine 56 angeordnet ist. Zwischen der elektrischen Kontaktplatte 60 und der Platine 56 befindet sich noch eine metallische Platte 62. Die Platine 56 ist über einen elektrischen Kontakt 62 mit der elektrischen Steckverbindung 58 verbunden. Die elektrische Steckverbindung 58 greift in entsprechende Kontakte 64 des elektrischen Antriebs 26. Zum Schutz der Platine 56 vor Verunreinigungen, die durch den elektrischen Antrieb 26, das Getriebe 28 sowie die Positionserfassung 32 verursacht werden können, ist die Platine 56, die metallische Platte 62 sowie die Kontaktplatte 60 und die metallische Platte 62 über ein Abdekkelement 68 von dem übrigen Gehäusebereich des Drosselklappenstutzens getrennt.The electrical connection means 44 of the housing cover 40 are connected via a circuit board 56 and an electrical connector 58 to the electric drive 26. In this case, an electrical contact plate 60 is provided for connecting the electrical connection means 44 of the housing cover 40 with the circuit board 56, which is arranged between the housing cover 40 and the circuit board 56. Between the electrical contact plate 60 and the circuit board 56 is still a metallic plate 62. The board 56 is connected via an electrical contact 62 with the electrical connector 58. The electrical connector 58 engages in corresponding contacts 64 of the electric drive 26. To protect the board 56 from contamination, which may be caused by the electric drive 26, the gear 28 and the position detection 32, the circuit board 56, the metallic plate 62 and the contact plate 60 and the metallic plate 62 via a Abdekkelement 68 separated from the remaining housing portion of the throttle body.

Das Abdeckelement 68, die Platine 56, die metallische Platte 62 weisen jeweils Bohrungen 70 auf, über die sie mittels als metallische Schrauben ausgebildeter Befestigungsmittel 72 an dem Gehäuse 12 des Drosselklappenstutzens 10 anzuordnen sind. Hierzu werden die als Schrauben ausgebildeten Befestigungsmittel 72 in dafür vorgesehene Öffnungen 74 des Gehäusedeckels gesteckt. Die als Schrauben ausgebildeten Befestigungsmittel 72 werden dann durch die metallische Platte 62, die Platine 56 und das Abdeckelement 68 hindurchgeführt und greifen dann in Gewinde 76 des Gehäuses 12, um die metallische Platte 62, die Platine 56 und das Abdeckelement 68 fest an dem Gehäuse 12 des Drosselklappenstutzens 10 anzuordnen. Die Befestigungsmittel 72 dienen hierbei nicht ausschließlich als Mittel zum Befestigen, sondern leiten auch beim Betrieb des Drosselklappenstutzens 10 in der Platine 56 entstehende Wärme über die metallische Platte 62 an das Gehäuse 12 des Drosselklappenstutzens 10 ab.The cover 68, the circuit board 56, the metallic plate 62 each have holes 70, via which they are to be arranged by means designed as metallic screws fastener 72 to the housing 12 of the throttle body 10. For this purpose, designed as a screw fastening means 72 are inserted into openings 74 provided for this purpose of the housing cover. The fasteners 72 formed as screws are then passed through the metallic plate 62, the circuit board 56 and the cover 68 and then engage in threads 76 of the housing 12 to the metallic plate 62, the board 56 and the cover 68 fixed to the housing 12th of the throttle body 10 to order. The fastening means 72 serve not only as means for fastening, but also dissipate in the operation of the throttle body 10 in the board 56 resulting heat through the metallic plate 62 to the housing 12 of the throttle body 10 from.

Auf der Platine 56 ist eine erste Elektronik 80 für den elektrischen Antrieb 26 und eine zweite Elektronik 82 für die außerhalb des Gehäuses 12 angeordneten elektrischen Geräte 46 angeordnet. Sowohl die erste Elektronik 80 als auch die zweite Elektronik 82 sind über die elektrische Kontaktplatte 60 und die in dem Gehäusedeckel 40 zumindest teilweise angeordneten elektrischen Verbindungsmittel 44 mit den außerhalb des Drosselklappenstutzens 10 angeordneten elektrischen Geräten 56 kontaktierbar. Die erste Elektronik 80 und die zweite Elektronik 82 sind in integrierter Bauweise auf die Platine 56 aufgebracht. Daher ist von außen nicht zu entscheiden, welcher Bereich der Platine 56 zu der ersten Elektronik 80 und welcher Bereich der Platine zu der zweiten Elektronik 82 gehört. Alternativ kann jedoch die Platine 46 auch deutlich von außen erkennbare Bereiche aufweisen, die für die erste Elektronik 80 und die zweite Elektronik 82 vorgesehen sind. Die zweite Elektronik 82 für die außerhalb des Gehäuses 12 des Drosselklappenstutzens 10 angeordneten Geräte 46 umfasst eine Steuereinheit 84A, eine Datenerfassungseinheit 84B und eine Datenspeichereinheit 84C, die gemeinsam in integrierter Weise in einem einzigen Baustein 84 angeordnet sind.On the circuit board 56, a first electronics 80 for the electric drive 26 and a second electronics 82 for the outside of the housing 12 arranged electrical devices 46 is arranged. Both the first electronics 80 and the second electronics 82 are contactable via the electrical contact plate 60 and in the housing cover 40 at least partially arranged electrical connection means 44 with the outside of the throttle body 10 arranged electrical devices 56. The first electronics 80 and the second electronics 82 are of integrated construction applied to the board 56. Therefore, it can not be decided from the outside which area of the board 56 belongs to the first electronics 80 and which area of the board belongs to the second electronics 82. Alternatively, however, the board 46 may also have clearly visible from the outside areas, which are provided for the first electronics 80 and the second electronics 82. The second electronics 82 for the devices 46 located outside the housing 12 of the throttle body 10 include a controller 84A, a data acquisition unit 84B, and a data storage unit 84C that are collectively disposed in a single package 84 in an integrated manner.

Das Deckelement 104 ist aus Kunststoff 108 gefertigt. Hierbei sind beim Fertigungsprozess des Deckelelements 104 elektrische Verbindungsmittel 110 in das Deckelelement 104 integriert worden, die zumindest teilweise vollständig von dem Kunststoff 108 umschlossen sind. Über die elektrischen Verbindungsmittel 110 ist das Deckelelement 104 des Elektronikmoduls 100 mit einem Drosselklappenstutzen 112, einem Zündungsgerät 114, einem Einspritzgerät 116, einem Ölstandsmessgerät 118 und einem Luftmassenreguliergerät 120 verbunden. Die elektrischen Geräte 122 sind im Kraftfahrzeug angeordnet, wobei das Zündungsgerät 114, das Einspritzgerät 116, das Ölstandsmessgerät 118 im Bereich des Verbrennungsmotors des Kraftfahrzeugs angeordnet sind. Weiterhin ist das Elektronikmodul 100 über das Deckelelement 104 mit einer Stromquelle verbunden, was in der Zeichnung nicht näher dargestellt ist.The electronic module 100 according to FIGS. 2 and 3 has electronics 102 for a motor vehicle. The electronic module 100 comprises a base element 106 which can be closed by a cover element 104. The cover element 104 is made of plastic 108.

Via the electrical connection means 110, the cover element 104 of the electronic module 100 is connected to a throttle body 112, an ignition device 114, an injection device 116, an oil level gauge 118 and a Luftmassenreguliergerät 120. The electrical devices 122 are arranged in the motor vehicle, wherein the ignition device 114, the injection device 116, the oil level gauge 118 are arranged in the region of the internal combustion engine of the motor vehicle. Furthermore, the electronic module 100 is connected via the lid member 104 to a power source, which is not shown in detail in the drawing.

Der Drosselklappenstutzen 112 umfaßt ein Gehäuse 112A mit einer durchgehenden Drosselöffnung 112B und eine in der Drosselöffnung 112B auf einer Drosselklappenwelle 112C schwenkbar angeordnete Drosselklappe 112D. Weiterhin ist in dem Gehäuse 112A des Drosselklappenstutzens 112 ein elektrischer Stellantrieb 112E zum Verschwenken der Drosselklappenwelle 112C angeordnet.The throttle body 112 includes a housing 112A having a continuous throttle opening 112B and a throttle shaft 112C in the throttle opening 112B pivotally arranged throttle 112D. Furthermore, in the housing 112A of the throttle body 112, an electric actuator 112E for pivoting the throttle shaft 112C is disposed.

In dem Deckelelement 104 des Elektronikmoduls 100 ist eine Platine 124 angeordnet. Auf der Platine 124 ist eine erste Elektronik 140 für den elektrischen Stellantrieb 112E der Drosselklappenwelle 112C des Drosselklappenstutzens 112 und eine zweite Elektronik 142 für die Vielzahl von elektrischen Geräten 122 angeordnet. Die erste Elektronik 140 des elektrischen Stellantriebs 112E der Drosselklappenwelle 112C und die zweite Elektronik für die Vielzahl von elektrischen Geräten 122 sind über die in dem Deckelelement 104 angeordneten elektrischen Verbindungsmittel 110 mit dem Drosselklappenstutzen 112 und den elektrischen Geräten 122 verbindbar. Die erste Elektronik 140 und die zweite Elektronik 142 sind in integrierter Weise auf die Platine 124 aufgebracht. Hierbei lassen sich aufgrund der integrierten Bauweise nicht räumliche Bereiche angeben, in denen die erste Elektronik 140 und die zweite Elektronik 142 auf der Platine 124 angeordnet sind. Alternativ kann die Platine 124 auch in äußerlich erkennbare Bereiche unterteilt sein, in denen die erste Elektronik 140 und die zweite Elektronik 142 angeordnet sind.In the cover element 104 of the electronic module 100, a circuit board 124 is arranged. On the board 124, a first electronics 140 for the electric actuator 112E of the throttle shaft 112C of the throttle body 112 and a second electronics 142 for the plurality of electrical devices 122 is arranged.

The first electronics 140 and the second electronics 142 are applied to the board 124 in an integrated manner. Due to the integrated design, it is not possible to specify spatial regions in which the first electronics 140 and the second electronics 142 are arranged on the printed circuit board 124. Alternatively, the board 124 may also be divided into externally visible areas in which the first electronics 140 and the second electronics 142 are arranged.

Zum Abführen der beim Betrieb der ersten Elektronik 140 und der zweiten Elektronik 142 entstehenden Wärme ist zusätzlich in dem Elektronikmodul 100 eine metallische Platte 144 angeordnet. Die metallische Platte 144 ist über Befestigungsmittel 146 an dem Basiselement 106 anzuordnen. Hierzu werden die als Schrauben ausgebildeten Befestigungsmittel 146 durch Öffnungen 148 des Deckelelementes 104 und Bohrungen der metallischen Platte 144 hindurchgeführt, um anschließend in Gewinde 150 des Basiselements 106 zu greifen, um in diese eingeschraubt zu werden. Die Platine 124 ist von der Seite des Basiselements 106 aus mit Schrauben an dem Basiselement 106 befestigt. Beim Betrieb der ersten Elektronik 140 und der zweiten Elektronik 142 entsteht Wärme auf der Platine 124. Diese Wäre wird von der metallischen Platte 144 aufgenommen und dann über die als Schrauben ausgebildeten Befestigungsmittel 146 an die aus Metall gefertigte Basiselement 106 weitergeleitet. Das Basiselement 106 ist dabei so in dem Kraftfahrzeug angeordnet, dass es von außen her ein Kühlung erfährt.For dissipating the heat generated during operation of the first electronics 140 and the second electronics 142, a metallic plate 144 is additionally arranged in the electronic module 100. The metallic plate 144 is to be attached to the base member 106 via fasteners 146. For this purpose, the fixing means 146 designed as screws are passed through openings 148 of the cover element 104 and bores of the metallic plate 144, in order then to engage in threads 150 of the base element 106 in order to be screwed into them. The board 124 is from the side of the base member 106 with screws attached to the base member 106. Heat is generated on the board 124 during operation of the first electronics 140 and second electronics 142. This heat is received by the metallic plate 144 and then relayed to the metal base element 106 via the fasteners 146 formed as screws. The base member 106 is arranged in the vehicle so that it undergoes cooling from the outside.

Alternativ zu dem in Figur 2 gezeigten Elektronikmodul 100 kann das Elektronikmodul 100 gemäß Figur 3 auch über elektrische Verbindungsmittel 110, die auf der Außenwand des Deckelements 104 angeordnet sind mit der Umgebung verbindbar sein, insbesondere mit den elektrischen Geräten 122. Die Bezugszeichen in Figur 3 entsprechen denen in Figur 2. Aufgrund dieser Übereinstimmung wird zur Funktion der einzelnen Bauteile auf die Figurenbeschreibung von Figur 2 verwiesen.As an alternative to the electronic module 100 shown in FIG. 2, the electronic module 100 according to FIG. 3 can also be connectable to the environment via electrical connection means 110 which are arranged on the outer wall of the cover element 104, in particular with the electrical devices 122.

Sowohl der Drosselklappenstutzen 10 als auch das Elektronikmodul 100 gemäß den Figuren 1 bzw. 2 bis 3 weisen durch ihre besonders kompakte Bauweise einen besonders geringen Platzbedarf auf. Zudem entfällt beim Drosselklappenstutzen 10 die Gefahr von fehlerhaften Signalübergängen von der ersten Elektronik 80 des elektrischen Antriebs 26 des Drosselklappenstutzens 10 zu der zweiten Elektronik 82 der elektrischen Geräte 46 des Kraftfahrzeugs. Das Elektronikmodul 100 ist universell anwendbar und an beliebiger Stelle im Kraftfahrzeug montierbar. Zu beachten ist hierbei lediglich, dass für eine besonders zuverlässige Signalübertragung die Verbindungen zu den elektrischen Geräten 122 nicht allzu groß sein dürfen.Both the throttle body 10 and the electronic module 100 according to the figures 1 and 2 to 3 have a particularly small footprint due to their particularly compact design. In addition eliminates the throttle valve neck 10, the risk of faulty signal transitions from the first electronics 80 of the electric drive 26 of the throttle body 10 to the second electronics 82 of the electrical equipment 46 of the motor vehicle. The electronics module 100 is universally applicable and can be mounted at any point in the motor vehicle. It should be noted here only that for a particularly reliable signal transmission, the connections to the electrical equipment 122 may not be too large.
