Abstract

The device has an undercut establishing a form-fit connection in stepped boreholes (6) of a housing block (1). A cover (2) is connected with the housing block (1) in a main stress direction in a force-fit manner. The cover serves as a component part of a hydraulic system for controlling gas exchange valves at lifting cylinder combustion engines. The cover is fastened at the housing block by rivets. The rivets stay in connection with boreholes (3) in the housing block by a press fit. The rivets are formed as pin rivets (5) and blind rivets (7).

Description

Gebiet der ErfindungField of the invention

Einrichtung zum Befestigen eines Bauteils, insbesondere eines Deckels, an einem Gehäuseblock, wobei das Bauteil mit dem Gehäuseblock in Hauptbeanspruchungsrichtung zumindest kraftschlüssig verbunden ist und vorzugsweise Bestandteil eines hydraulischen Systems zur Steuerung von Gaswechselventilen an Hubkolbenbrennkraftmaschinen ist.Device for attaching a component, in particular a cover, to a housing block, wherein the component is connected to the housing block in the main direction of stress at least non-positively and is preferably part of a hydraulic system for controlling gas exchange valves on reciprocating internal combustion engines.

Hintergrund der ErfindungBackground of the invention

Es ist eine Hydraulikeinheit für einen Zylinderkopf einer Brennkraftmaschine mit hydraulisch variablem Gaswechselventiltrieb bekannt, DE- 10 2009 011 983 A1 , bei der Gehäuseoberteile mittels Schrauben an einem Gehäuseblock dichtend befestigt sind. Um den Anforderungen an die Dichtheit gerecht zu werden, ist eine verhältnismäßig hohe Anzahl von Schrauben mit den dazugehörigen Gewinden im Gehäuseblock erforderlich.It is a hydraulic unit for a cylinder head of an internal combustion engine with hydraulically variable gas exchange valve train known DE-10 2009 011 983 A1 , in which housing upper parts are fastened in a sealing manner by means of screws to a housing block. To meet the requirements for tightness, a relatively large number of screws with the associated threads in the housing block is required.

Da eine Demontierbarkeit des Deckels nicht erforderlich ist, ist der Aufwand für die Schrauben mit einer geeigneten Güteklasse sowie die Bohrungen mit Gewinden in dem Gehäuseblock sehr aufwendig. Darüber hinaus ist der Montageaufwand nicht unerheblich.Since a disassembly of the lid is not required, the cost of the screws with a suitable grade and the holes with threads in the housing block is very expensive. In addition, the installation effort is not insignificant.

Aufgabe der ErfindungObject of the invention

Aufgabe der Erfindung ist es daher, ein Befestigungskonzept zur Verfügung zu stellen, mit dem das Bauteil bzw. der Deckel an einem Gehäuseblock kostengünstig befestigt werden kann. Das Bauteil soll einfach und schnell montierbar und kostengünstig bezüglich Befestigungsmaterial und Montageaufwand sein.The object of the invention is therefore to provide a fastening concept with which the component or the lid can be attached to a housing block inexpensively. The component should be easy and quick to install and inexpensive in terms of mounting hardware and assembly costs.

Zusammenfassung der ErfindungSummary of the invention

Die Aufgabe der Erfindung wird dadurch gelöst, dass das Bauteil mittels Nieten an dem Gehäuseblock befestigt ist.The object of the invention is achieved in that the component is fastened by means of rivets to the housing block.

Der Gehäuseblock braucht hierbei lediglich mit Bohrungen statt mit Bohrungen und Innengewinden zu versehen werden. Der Deckel kann unverändert bleiben, während die Befestigung über Nieten erfolgt.The housing block only needs to be provided with holes instead of holes and internal threads. The lid can remain unchanged, while the attachment is made via rivets.

Die als Stiftnieten ausgebildeten Nieten können mittels Presssitz mit den Bohrungen im Gehäuseblock in Verbindung stehen, so dass eine gute Befestigung des Deckels am Gehäuseblock gegeben ist.The rivets designed as pin rivets can be in contact with the bores in the housing block by means of a press fit, so that a good fastening of the cover to the housing block is provided.

Die Nieten können aber auch als Blindnieten ausgebildet sein und mit einem Hinterschnitt in den Bohrungen des Gehäuseblocks nach Verspannung eine formschlüssige Verbindung eingehen.However, the rivets can also be designed as blind rivets and form an interlocking connection with an undercut in the bores of the housing block after bracing.

Eine Befestigung mittels Nieten ist in vielen technischen Bereichen bekannt. Zur Befestigung von Deckeln an einem Gehäuseblock zur Abdichtung im Bereich Automotive/Motorenentwicklung ist dieses Konzept nicht bekannt.An attachment by riveting is known in many technical fields. This concept is not known for attaching covers to a housing block for sealing in the field of automotive / engine development.

Detaillierte Beschreibung der ZeichnungDetailed description of the drawing

In 1 ist mit 1 ein Gehäuseblock bezeichnet, an dem ein Deckel 2 anliegt, der an dem Gehäuseblock 1 befestigt werden soll. In der einen, rechts dargestellten Version, weist der Gehäuseblock 1 Bohrungen 3 auf. In Verlängerung dieser Bohrungen 3 sind im Deckel 2 Öffnungen 4 vorgesehen.In 1 is with 1 a housing block referred to which a lid 2 rests against the housing block 1 should be attached. In one, the version shown on the right, the housing block 1 drilling 3 on. In extension of these holes 3 are in the lid 2 openings 4 intended.

Mit 5 sind Stiftnieten bezeichnet, die einen etwas größeren Schaftdurchmesser aufweisen als der Durchmesser der Bohrungen 3, so dass in Stiftnieten in die Bohrungen 3 eingepresst bzw. eingeschlagen werden und mit den Bohrungen 3 eine feste Verbindung eingehen.With 5 are called pin rivets, which have a slightly larger shaft diameter than the diameter of the holes 3 , so in stud rivets in the holes 3 be pressed or hammered and with the holes 3 make a firm connection.

In dem zweiten Ausführungsbeispiel, linke Darstellung in 1, sind im Gehäuseblock 1 Stufenbohrungen 6 eingearbeitet. In diesem Ausführungsbeispiel kommen Blindnieten 7 zur Anwendung, die nach Einschieben durch die Öffnungen 4 im Deckel 2 in die Stufenbohrungen 6 gelangen und durch Verspannen eine formschlüssige Verbindung in den Stufenbohrungen bilden.In the second embodiment, left illustration in 1 , are in the housing block 1 stepped holes 6 incorporated. Blind rivets are used in this embodiment 7 for use after insertion through the openings 4 in the lid 2 into the stepped holes 6 reach and form by clamping a positive connection in the stepped holes.
