Description

Die Erfindung betrifft ein hydraulisches Steuergerät mit einem Gehäuse aus Leichtmetall und Anschlußeinrichtungen zur Verbindung mit Hydraulikleitungen.The invention relates to a hydraulic control unit with a housing made of light metal and Connection devices for connection to hydraulic lines.

Hydraulische Steuergeräte bestehen aus einem Gehäuse, an dem weitere hydraulische Einrichtungen, wie Ventile, Filter etc. gehalten sind. Das Gehäuse hat die Aufgabe, die Ströme der Hydraulikflüssigkeit zu führen; hierzu sind im Gehäuse Leitungen in Form von Nuten vorgesehen. Zur Verbindung mit der zu steuernden Einrichtung, beispielsweise einem Fahrzeuggetriebe, ist es meist vorgesehen, daß das Steuergerät unmittelbar auf die zu steuernde Einrichtung aufgesetzt ist und die hydraulische Verbindung durch korrespondierende Öffnungen in einer Flanschfläche hergestellt wird. Meist sind über diese internen Anschlüsse hinaus externe Anschlüsse vorgesehen, wie z.B. zur Versorgung mit hydraulischer Druckflüssigkeit und Abgängen zu externen hydraulischen Geräten, die ebenfalls von dem Steuergerät beaufschlagt werden sollen.Hydraulic control units consist of a housing on which further hydraulic devices, such as valves, filters etc. are held. The housing's job is to control the flows of hydraulic fluid respectively; for this purpose, lines in the form of grooves are provided in the housing. To connect with the to controlling device, for example a vehicle transmission, it is usually provided that the Control unit is placed directly on the device to be controlled and the hydraulic Connection is made through corresponding openings in a flange surface. Most are over these internal connections also provide external connections such as to supply with hydraulic hydraulic fluid and outlets to external hydraulic equipment, also from the Control unit to be acted upon.

Aus Gewichtsgründen und wegen der leichteren Herstellbarkeit und Bearbeitbarkeit sind die Gehäuse für derartige Steuergeräte meist aus Leichtmetall gefertigt. Im Bereich der externen Anschlußeinrichtungen stellt sich nun das Problem, daß bei der Montage der externen Verbindungen vergleichsweise große Kräfte, wie z.B. Anzugsmomente bei Schraubverbindungen, aufgebracht werden müssen, um die Verbindung gegenüber dem hydraulischen Druck sicher abzudichten. Gerade in Leichtmetallgehäusen liegen jedoch die Kräfte, bei denen das Gehäuse, beispielsweise durch Ausreißen eines Gewindes, beschädigt wird, nur wenig über den zur Abdichtung notwendigen Kräften; insbesondere können die zu Beschädigungen führenden Kräfte ohne weiteres von Hand aufgebracht werden. Durch eine solche Beschädigung ist dann auch das sehr teure Gehäuse des Steuergerätes beschädigt und muß aufwendig repariert bzw. ersetzt werden.For reasons of weight and because they are easier to manufacture and process, the housings are for such control units mostly made of light metal. In the area of external Connection devices now pose the problem that when installing the external connections comparatively large forces, e.g. Tightening torques for screw connections in order to securely seal the connection against the hydraulic pressure. Currently at However, light metal housings are the forces at which the housing, for example, by Pulling out a thread, is damaged, only slightly above the forces required for sealing; in particular, the forces leading to damage can easily be applied by hand become. Such damage will then also result in the very expensive housing of the control unit damaged and must be laboriously repaired or replaced.

Gegenüber diesem Stand der Technik ist es Aufgabe der Erfindung, die Gefahr einer Beschädigung des Gehäuses im Bereich der Anschlußeinrichtungen zu vermindern.Compared to this prior art, it is an object of the invention to reduce the risk of damage to reduce the housing in the area of the connection devices.

Erfindungsgemäß erfolgt die Lösung dieser Aufgabe mit den Merkmalen des Patentanspruches 1. Es wird vorgeschlagen, zur Aufnahme der Anschlußeinrichtungen eine Platte aus Stahl vorzusehen, die an einer Flanschfläche des Gehäuses gehalten ist. Gegenüber dem aus Leichtmetall gefertigten Gehäuse ist die Stahlplatte wesentlich unempfindlicher gegenüber Beschädigungen, da die Kräfte, die zu einer Beschädigung führen, wesentlich höher sind. Sollte es dennoch zu einer Beschädigung bei der Montage der Anschlußeinrichtungen kommen, so ist nur die Stahlplatte auszutauschen, während das Steuergerät selbst nicht einmal demontiert werden muß, so daß dieser Austausch besonders rasch und kostengünstig erfolgen kann. According to the invention, this object is achieved with the features of claim 1 It is proposed to provide a plate made of steel to accommodate the connection devices a flange surface of the housing is held. Compared to the housing made of light metal The steel plate is much less sensitive to damage, since the forces that lead to it Cause damage, are significantly higher. Should there still be damage to the Assembly of the connection devices come, so only the steel plate must be replaced, while the Control unit itself does not even have to be dismantled, so that this exchange is particularly quick and can be done inexpensively.

Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.Advantageous developments of the invention are described in the subclaims.

So wird vorgeschlagen, daß in der Platte zur Aufnahme der Anschlußeinrichtungen Bohrungen mit Gewinde vorgesehen sind, die mit in der Flanschfläche angeordneten Leitungsbohrungen des Gehäuses korrespondieren. In dieser Anwendung sind die Vorteile der Erfindung in besonderem Maße spürbar, da gerade bei einer Schraubverbindung im Bereich der Anschlußeinrichtungen die Gefahr einer Beschädigung durch ein zu hohes Anzugsmoment besonders groß ist.So it is proposed that holes in the plate for receiving the connection devices Threads are provided, which are arranged in the flange surface with line bores Housing correspond. In this application, the advantages of the invention are particularly great noticeable, since there is a danger in the case of a screw connection in the area of the connection devices damage caused by excessive tightening torque is particularly large.

Es wird ferner vorgeschlagen, zwischen der Stahlplatte und der Flanschfläche eine Dichtung vorzusehen, um so ein Austreten von Hydraulikflüssigkeit im Bereich der Flanschfläche zu vermeiden. Eine derartige Dichtung kann beispielsweise als in die Stahlplatte eingelegte Formdichtung, als auf die Platte aufgelegte Flachdichtung, oder in Form von eingelegten O-Ringen im Bereich der Leitungsbohrungen ausgeführt sein.It is also proposed to have a seal between the steel plate and the flange surface To prevent hydraulic fluid from escaping in the area of the flange surface. Such a seal can, for example, as a molded seal inserted into the steel plate, as on the Flat gasket on top, or in the form of inserted O-rings in the area of the Line holes must be made.

Soweit die Leitungsbohrungen in der Flanschfläche (Einsatz-) Ventile aufnehmen sollen, ist es ferner vorgesehen, daß die Platte gleichzeitig das Widerlager für diese Ventile bildet. Ein solches Widerlager ist beispielsweise dann erforderlich, wenn der Ventileinsatz als vorgespanntes Rückschlagventil ausgeführt ist und daher eine am Rückschlagventil angeordnete Feder zum Aufbringen der Vorspannkraft abzustützen ist.To the extent that the line bores in the flange surface are to accommodate (insert) valves, it is also provided that the plate also forms the abutment for these valves. Such an abutment is required, for example, if the valve insert is a pre-stressed check valve is executed and therefore a spring arranged on the check valve for applying the Preload must be supported.

Schließlich wird vorgeschlagen, seitlich an der Platte Vorsprünge vorzusehen, die an seitlichen Flächen der Flanschfläche anliegen. Durch diese Ausformung der Platte können die bei der Montage der Anschlußeinrichtungen in die Platte eingeleiteten Drehmomente formschlüssig abgestützt werden, so daß diese Belastung nicht von den Befestigungseinrichtungen der Platte aufgenommen werden muß. Ein bevorzugtes Anbindungsgebiet der Erfindung sind hydraulisch betätigte Fahrzeuggetriebe.Finally, it is proposed to provide projections on the side of the plate, on the lateral surfaces of the flange surface. This shape of the plate can be used during assembly of the Connection devices in the plate introduced torques are positively supported, so that this load does not have to be absorbed by the fastening devices of the plate. A preferred connection area of the invention are hydraulically operated vehicle transmissions.
