Abstract
Description
Die Erfindung betrifft einen Gehäusedeckel, insbesondere für eine Antriebseinheit einer Fahrzeug-Servolenkung, der Teil einer Begrenzung eines Aufnahmeraums ist, in dem elektronische Steuerbauteile vorgesehen sind.The The invention relates to a housing cover, in particular for one Drive unit of a vehicle power steering, the part of a boundary a receiving space is provided in the electronic control components are.
Des weiteren betrifft die Erfindung auch eine Antriebseinheit für eine Fahrzeug-Servolenkung mit einem solchen Gehäusedeckel.Of Furthermore, the invention also relates to a drive unit for a vehicle power steering with a such housing cover.
Die Antriebseinheit kann bei elektrischen Servolenkungen beispielsweise eine vorgefertigte Baugruppe aus einem Motor und einer elektronischen Steuerung sein. Für die in den heutigen Kraftfahrzeugen überwiegend eingesetzten hydraulischen Servolenkungen werden als Antriebseinheit in der Regel Motor-Pumpen-Aggregate verwendet, die allgemein aus dem Stand der Technik bekannt sind. Sie weisen gewöhnlich einen Antriebsmotor, eine Pumpe und einen Tank auf, wobei die Pumpe dazu dient, einer Servolenkung unter Druck stehendes Hydraulikfluid zuzuführen. Darüber hinaus sind im Stand der Technik bereits Motor-Pumpen-Aggregate offenbart, bei denen eine elektronische Steuereinheit integriert ist. Üblicherweise ist dabei für diese Steuereinheit ein Aufnahmeraum vorgesehen, der nach dem Einbau der elektronischen Steuerbauteile durch einen Deckel verschlossen wird, so daß die Steuerungselektronik geschützt im geschlossenen Aufnahmeraum liegt.The Drive unit can be used in electric power steering, for example a prefabricated assembly of a motor and an electronic Be control. For the predominantly hydraulic power steering systems used in today's motor vehicles are used as a drive unit usually motor-pump units, which are generally known from the prior art. They point usually a drive motor, a pump and a tank, wherein the pump Serves, a power steering pressurized hydraulic fluid supply. About that In addition, engine-pump units are already disclosed in the prior art, in where an electronic control unit is integrated. Usually is there for This control unit provided a receiving space, which after installation of the electronic control components is closed by a lid, So that the Control electronics protected in the closed reception room.
Bei elektrisch angetriebenen Motor-Pumpen-Aggregaten für Servolenksysteme in Kraftfahrzeugen können im Motor oder in der Pumpe Geräusche entstehen, die im Fahrzeug bzw. außerhalb des Fahrzeugs als unangenehm empfunden werden. Aus dem Stand der Technik sind bereits mehrere Maßnahmen zur Dämpfung dieser Geräusche bekannt. Die Maßnahmen sind dabei stets auf die schallemittierenden Bauteile selbst (Motor, Pumpe) oder deren Aufnahmeräume (z.B. Motorraum, Tankraum) beschränkt.at electrically driven motor-pump units for power steering systems in motor vehicles can Noises in the engine or in the pump arise in the vehicle or outside the vehicle as unpleasant be felt. Several already exist in the prior art activities for damping this Sounds known. The measures are always on the sound-emitting components themselves (engine, Pump) or their receiving spaces (e.g., engine compartment, tank space).
Aufgabe der Erfindung ist es, die entstehenden Geräusche noch besser zu dämpfen und den Schallpegel einer Antriebseinheit für Servolenkungen insgesamt weiter zu senken.task The invention is to dampen the resulting noise even better and the sound level of a drive unit for power steering systems in total continue to lower.
Diese Aufgabe wird durch einen Gehäusedeckel gelöst, der aus Sandwichblech hergestellt ist. Dies ist bemerkenswert, weil der Gehäusedeckel nicht den Motor- oder Pumpenraum mit ihren jeweiligen, schallemittierenden Bauteilen (Motor, Pumpe) begrenzt, sondern zur Begrenzung eines Aufnahmeraums beiträgt, in dem elektronische Steuerbauteile vorgesehen sind. Die elektronischen Steuerbauteile selbst verursachen jedoch gar keine oder zumindest keine nennenswerten Geräusche, die im Inneren oder außerhalb des Fahrzeugs wahrgenommen werden könnten. Dennoch kann durch den Einsatz eines gegenüber einem herkömmlichen, einlagigen Blechdeckel etwas aufwendiger zu fertigenden Gehäusedeckels aus Sandwichblech der Schallpegel der Antriebseinheit (z.B. des Motor-Pumpen-Aggregats) insgesamt abgesenkt werden.These Task is through a housing cover solved, which is made of sandwich sheet metal. This is remarkable because the housing cover not the engine or pump room with their respective, sound-emitting Components (motor, pump) limited, but to limit a Contributes to the recording room, in which electronic control components are provided. The electronic However, control components themselves do not cause any or at least none notable sounds, the inside or outside the vehicle could be perceived. Nevertheless, by the Use of one opposite a conventional, single-layered sheet metal lid a little more expensive to produce housing cover sandwich panel, the sound level of the drive unit (e.g. Engine-pump unit) in total be lowered.
In einer bevorzugten Ausführungsform ist in dem Aufnahmeraum ausschließlich eine elektronische Steuereinheit aufgenommen.In a preferred embodiment is in the recording room exclusively an electronic control unit added.
Das Sandwichblech umfaßt vorzugsweise zwei Blechlagen mit dazwischenliegender viskoelastischer Klebeschicht. Die Klebemasse zwischen den Blechlagen dient dazu, die Übertragung von Körperschall von einer Blechlage zur anderen zu dämpfen. In weiteren Ausführungsvarianten können die Sandwichbleche selbstverständlich auch mehr als zwei Blechlagen mit jeweils dazwischenliegender Klebeschicht aufweisen.The Sandwich sheet covered preferably two sheet metal layers with intermediate viscoelastic Adhesive layer. The adhesive between the sheet metal layers serves to the transfer of structure-borne noise from one sheet metal layer to another. In further embodiments can the sandwich panels of course Also more than two layers of sheet metal, each with intermediate adhesive layer exhibit.
Vorzugsweise ist die viskoelastische Klebeschicht maximal 0,1 mm, besonders bevorzugt etwa 0,05 mm dick. Klebeschichtdicken in diesem Bereich führen zu kaum relevanten Änderungen in den äußeren Bauteilabmessungen, reichen aber aus, um eine hinreichende Schwingungsentkopplung der Blechlagen zu erzielen.Preferably the viscoelastic adhesive layer is at most 0.1 mm, particularly preferred about 0.05 mm thick. Adhesive layer thicknesses in this area increase hardly relevant changes in the outer component dimensions, But sufficient to a sufficient decoupling of vibration of To achieve sheet metal layers.
Die Blechlagen können eine Dicke von maximal 1 mm, vorzugsweise etwa 0,6 mm aufweisen. Damit können die Blechlagen so dünn gefertigt werden, daß sie im Bereich der halben Blechdicke einlagiger Bleche aus dem Stand der Technik (1,5 bis 2 mm) liegen. Somit bleiben der Materialbedarf und die äußeren Bauteilabmessungen weitgehend konstant.The Sheet metal layers can have a thickness of at most 1 mm, preferably about 0.6 mm. In order to can the sheet metal layers so thin be made that they in the range of half the sheet thickness of single-layer sheets from the stand technology (1.5 to 2 mm). Thus, the material requirements remain and the outer component dimensions largely constant.
Vorzugsweise sind die Blechlagen aus einem Stahl der Sorte DX54D+ZA gefertigt. Dieser Stahl ist ein sogenannter weicher Stahl mit einem Zink-Aluminium-Überzug, der hervorragend für das bei derartigen Gehäusedeckeln übliche Kaltumformen geeignet ist.Preferably the sheet metal layers are made of DX54D + ZA steel. This steel is a so-called soft steel with a zinc-aluminum coating, which is excellent for such housing covers conventional cold forming suitable is.
Die Erfindung betrifft auch eine Antriebseinheit, insbesondere für eine Fahrzeug-Servolenkung, mit einem Gehäusebauteil und einem oben beschriebenen Gehäusedeckel, wobei das Gehäusebauteil und der Gehäusedeckel den Aufnahmeraum ausbilden.The The invention also relates to a drive unit, in particular for a vehicle power steering, with a housing component and a housing cover described above, the housing component and the housing cover train the recording room.
Insbesondere kann das Gehäusebauteil ein Gehäusefortsatz eines Motorgehäuses der Antriebseinheit sein.Especially can the housing component a housing extension a motor housing be the drive unit.
