Abstract

The invention relates to a sun roof (2), which can be actuated by servo motor, for motor vehicles (1) which are driven by an internal combustion engine, in which motor vehicles (1) the sun roof cover (3) can be moved by means of a reversible lifting piston (15) which can be acted on by pressure. In order to dispense with a separate pressure pump, a vacuum accumulator (6) which is charged from the manifold (5) of the internal combustion engine (4) is used as pressure source. <IMAGE>

Description

Servomotorisch betätigbares Schiebedach für brennkraftgetriebeneServomotor-operated sunroof for combustion-powered ones

Kraftfahrzeuge Die Erfindung betrifft ein servomotorisch betätigbares Schiebedach für brennkraftgetriebene Kraftfahrzeuge nach dem Oberbegriff des Anspruchs, wie er beispielsweise aus Fahrzeugen der Anmelderin als bekannt hervorgeht.Motor vehicles The invention relates to a servomotor actuatable Sunroof for internal combustion vehicles according to the preamble of the claim, as it emerges as known, for example, from vehicles of the applicant.

Bei diesen Fahrzeugen handelt es sich um solche der Luxusklasse, mit einer sogenannten Komfort-Hydraulik, bei der der Schiebedeckel des Schiebedaches mittels eines reversierbaren Hydraulikzylinders in Verschieberichtung bewegbar ist.These vehicles are those of the luxury class, with a so-called comfort hydraulics, in which the sliding cover of the sliding roof can be moved in the displacement direction by means of a reversible hydraulic cylinder.

Aus der DE-OS 16 30 287 geht als bekannt hervor, den Schiebedeckel vertikal unter Zuhilfenahme von Vakuum aus dem Dachausschnitt abzusenken bzw. in ihn hinein zu heben. Die vertikalgerichteten Servokräfte können auch im Offnungszustand des Schiebedeckels dazu ausgenutzt werden, den Schiebedeckel in der jeweiligen Uffnungsstelung festzubremsen.DE-OS 16 30 287 is known to be the sliding cover vertically with the aid of a vacuum from the roof cutout or in to lift him in. The vertically directed servo forces can also be used in the open state of the sliding cover can be used, the sliding cover in the respective opening position to brake.

Die gattungsmäßig zugrundc gelegtc vorbekannte Schiebedachbetätigung mit hydraulischem Hubkolben hat den Nachteil, daß dafür eine gesonderte Hydraulikpumpe vorgesehen werden muß. Dieser Aufwand erscheint nicht vertretbar, wenn die Schiebedachbetätigung der einzige Druckverbraucher ist.The previously known sunroof actuation is based on the generic type with a hydraulic reciprocating piston has the disadvantage that it has a separate hydraulic pump must be provided. This effort does not appear to be justifiable if the sunroof is operated is the only print consumer.

Aufgabe der Erfindung ist es, eine Schiebedachbetätigung der zugrunde gelegten Art anzugeben, die ohne gesonderte Druckerhöhungspumpe auskommt.The object of the invention is to provide a sunroof actuation system specified type that does without a separate booster pump.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs gelöst. Der Hubkolben wird für pneumatische Beaufschlagung ausgelegt und mit gespeichertem Vakuum beaufschlagt, welches am Saugrohr der Brennkraftmaschine abgenommen werden kann.According to the invention, this object is achieved by the characterizing features of the claim solved. The reciprocating piston is designed for pneumatic loading and applied with stored vacuum, which is applied to the intake manifold of the internal combustion engine can be removed.

Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispieles nachfolgend noch kurz erläutert. Dabei zeigt die Figur die Ansicht auf ein bren£ikraftbetriebenes Fahrzeug mit pneumatisch betätigbarem Schiebedach.The invention is based on an embodiment shown in the drawing briefly explained below. The figure shows the view of a combustion engine Vehicle with pneumatically operated sliding roof.

Das in der Zeichnung gezeigte Kraftfahrzeug 1 weist ein Schiebedach 2 mit einem Schiebedeckel 3 auf, der innerhalb einer Führung längsverschiebbar ist (Verschieberichtung 8). Zur Erleichterung des Verschiebens des Schiebedeckels ist dieser in Verschieberichtung mit einem wechselweise druckbeaufschlagbarem Hubkolben 15 gekoppelt, der im wesentlichen aus einem beidseitig beaufschlagbarem Kolben 9, einer Kolbenstange 10 und einem Zylinder 11 mit zwei unterschiedlichen Druckanschlüssen besteht. Zur Einsparung einer gesonderten Arbeitspumpe hierfür wird das an dem Saugrohr 5 der Brennkraftmaschine 4 anstehende Vakuum ausgenützt, welches über ein Rückschlagventil 7 in dem Vakuumspeicher 6 gespeichert wird. Von dort führt eine Leitung zu einem im Griffbereich des Fahres liegenden Wechselventil 12, von dem eine Offnungsleitung 13 und eine Schließleitung 14 zu den jeweiligen Anschlüssen des Hubkolbens führen. Durch das Wechselventil 12 kann wahlweise eine der beiden Leitungen 13 bzw. 14 mit gespeichertem Vakuum beaufschlagt oder - in einer Neutralstellung - beide Leitungen belüftet werden.The motor vehicle 1 shown in the drawing has a sliding roof 2 with a sliding cover 3 which is longitudinally displaceable within a guide (Shift direction 8). To make it easier to move the sliding cover this in the direction of displacement with a reciprocating piston that can be alternately pressurized 15 coupled, which essentially consists of a piston 9, which can be acted upon on both sides, a piston rod 10 and a cylinder 11 with two different pressure connections consists. To save a separate working pump for this purpose, this is done on the suction pipe 5 of the internal combustion engine 4 used vacuum, which is via a check valve 7 is stored in the vacuum accumulator 6. From there a line leads to you In the grip area of the driver lying shuttle valve 12, of which an opening line 13 and a closing line 14 lead to the respective connections of the reciprocating piston. Through the shuttle valve 12, one of the two lines 13 or 14 can optionally be used stored vacuum is applied or - in a neutral position - both lines be ventilated.

Sollte der Einbauraum innerhalb des Daches für den Hubkolben 15 zu klein sein, so kann der Hubkolben auch unterhalb der Hutablage im Kofferraum des Kraftfahrzeuges eingebaut werden, wobei die Kolbenstange 10 über einen Bowden-Zug oder dergleichen mit dem Schiebedeckel zu verbinden wäre. Es können sich sowohl aufgrund des Durchmessers als auch aufgrund seiner Länge Platzprobleme ergeben.Should the installation space within the roof for the reciprocating piston 15 too be small, the reciprocating piston can also be located underneath the parcel shelf in the trunk of the Motor vehicle are installed, the piston rod 10 via a Bowden cable or the like would be connected to the sliding cover. It can be both due to the diameter as well as its length give rise to space problems.

Zwar könnte anstelle eines gesonderten Vakuumspeichers der Unterdruck auch in einem pneumatischen unterdruckgespeisten Bremskraftverstärker gespeichert werden. Ein gesonderter Vakuumspeicher hat jedoch dem gegenüber den Vorteil, daß das innerhalb des Bremskraftverstärkers gespeicherte Vakuum ausschließlich für Bremszwecke zur Verfügung steht und nicht etwa für eine Schiebedachbetätigung verbraucht werden kann. Wegen der höheren Priorität des Bremskraftverstärkers gegenüber einer Schiebedachbetätigung wird zweckmäßigerweise eine Rangfolgesteuerung zwischen beiden Vakuumspeichern vorgesehen, die sicherstellt, daß auf jeden Fall vor einer .4ufladung des Vakuumspeichers 6 der Speicher des Bremskraftverstärkers aufgeladen ist.It is true that the negative pressure could be used instead of a separate vacuum accumulator also stored in a pneumatic vacuum-fed brake booster will. However, a separate vacuum accumulator has the advantage that the vacuum stored inside the brake booster for braking purposes only is available and not used to operate the sunroof can. Because of the higher priority of the brake booster over sunroof operation a priority control between the two vacuum accumulators is expediently provided, which ensures that in any case before the vacuum accumulator is charged 6 the brake booster memory is charged.
