Description

Die Erfindung betrifft eine Vorrichtung zum Öffnen und Schließen des Lukendeckels einer Schiebeluke an einem Kampffahrzeug, insbesondere einem Kampfpanzer mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for opening and closing the hatch cover a sliding hatch on a combat vehicle, especially one Main battle tank with the features from the preamble of patent claim 1.

Schiebeluken an Kampffahrzeugen mit einer derartigen Vorrichtung zum Öffnen und Schließen des Lukendeckels sind bekannt und beispielsweise in DE 42 40 140 A1 und DE 195 04 922 A1 beschrieben.Sliding hatches on combat vehicles with such a device for opening and closing the hatch cover are known and for example in DE 42 40 140 A1 and DE 195 04 922 A1 are described.

Die Anordnung einer automatischen Brems- und Arretiervorrichtung in einer derartigen Vorrichtung ist aus Sicherheitsgründen außerordentlich wichtig, da, um das Bedienungspersonal nicht zu gefährden, der schwere Lukendeckel einer Schiebeluke in jeder beliebigen Position auch bei einer äußeren Krafteinwirkung, die beispielsweise durch eine Schrägstellung des Kampffahrzeugs verursacht sein kann, keine unerwünschten Eigenbewegungen ausführen darf und insbesondere niemals unter seinem Eigengewicht von selbst zufallen darf. Andererseits soll der Lukendeckel mittels einer manuellen Betätigungsvorrichtung auch bei größeren Schräglagen des Kampffahrzeugs mit zumutbarem Kraftaufwand geöffnet und geschlossen werden können und zwar sowohl aus dem Innenraum des Fahrzeugs als auch von außen.The arrangement of an automatic braking and locking device in one such a device is extremely important for safety reasons because in order not to endanger the operating personnel, the heavy hatch cover one Sliding hatch in any position, even with external force, caused, for example, by tilting the combat vehicle can be, must not carry out any undesired own movements and in particular, never fall under its own weight. On the other hand the hatch cover is to be operated manually even with larger inclinations of the combat vehicle with reasonable effort can be opened and closed, both from the Interior of the vehicle as well as from the outside.

Bisher wurde bei derartigen Vorrichtungen als automatische Brems- und Arretiervorrichtung ein innerhalb des Untersetzungsgetriebes auf der Abtriebsseite angeordneter selbsthemmender Schneckentrieb eingesetzt. Dieser hat jedoch den Nachteil, daß die Konstruktion relativ teuer wird und einen großen Einbauraum erfordert, daß beim Schneckentrieb keine parallelen Wellen vorhanden sind und Axialkräfte aufgenommen werden müssen. Weiterhin hat, bedingt durch den kleinen Steigungswinkel, der selbsthemmende Schneckentrieb einen äußerst geringen Wirkungsgrad im Vortrieb und bedingt somit erhöhte Antriebsleistungen. Ein maximaler Wirkungsgrad wird nur erreicht, wenn größere Abmessungen verwendet werden, eine aufwendige Einlaufprozedur vorgenommen wird und relativ hohe Antriebsdrehzahlen realisiert sind. Zudem muß konstruktiv die hohe und oftmals unerwünschte Übersetzung ins Langsame berücksichtigt werden.So far, such devices have been used as an automatic braking and locking device one inside the reduction gear on the driven side arranged self-locking worm gear used. However, this has the disadvantage that the construction is relatively expensive and a large installation space requires that there are no parallel shafts in the worm gear are and axial forces must be absorbed. Furthermore, has conditionally due to the small pitch angle, the self-locking worm gear extremely low efficiency in propulsion and therefore requires increased drive power. Maximum efficiency is only achieved when larger Dimensions are used, an elaborate running-in procedure made is and relatively high drive speeds are realized. In addition, must constructively the high and often undesirable slow translation be taken into account.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung mit den Merkmalen aus dem Oberbegriff des Patentanspruchs 1 so auszubilden, daß sie bei verringertem Einbauraum weniger kostspielig ist, bei der alle Wellen, einschließlich der Antriebs- und Abtriebswelle parallel verlaufen und die bei hoher Sicherheit einen guten Wirkungsgrad garantiert. The invention has for its object a device with the features form from the preamble of claim 1 so that they at reduced installation space is less expensive, including all shafts the input and output shafts run parallel and those at high Security guarantees good efficiency.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen aus dem kennzeichnenden Teil des Patentanspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen beschrieben.This object is achieved according to the invention with the features the characterizing part of claim 1. Advantageous further developments the invention are described in the dependent claims.

Der Grundgedanke der Erfindung besteht darin, anstelle eines selbsthemmenden Schneckentriebs als automatische Brems- und Arretiervorrichtung eine Klemmrollen-Lastmomentsperre zu verwenden, die bisher bei derartigen Vorrichtungen nicht eingesetzt wurde, weil man der Auffassung war, daß sie die notwendige Sicherheit und Funktionstüchtigkeit, insbesondere bei voreilenden Lasten nicht aufweise. Es hat sich aber überraschenderweise herausgestellt, daß eine Klemmrollen-Lastmoment-sperre einsetzbar ist, wenn dafür Sorge getragen wird, daß der Klemmwinkel innerhalb eines vorgegebenen Bereiches oberhalb des üblichen Klemmwinkelbereiches liegt und die Klemmrollen durch Druckfedern mit einer genügend hohen Gesamtkraft belastet werden.The basic idea of the invention is instead of a self-locking Worm drives as an automatic braking and locking device To use pinch roller load torque lock, which was previously used in such devices was not used because it was believed that it was the Necessary safety and functionality, especially with leading ones Do not show loads. Surprisingly, it has been found that a pinch roller load moment lock can be used if taken care of is that the clamping angle is above a predetermined range of the usual clamping angle range and through the pinch rollers Compression springs are loaded with a sufficiently high total force.

Die Klemmrollen-Lastmomentsperre hat dann den Vorteil, daß sie im Vortrieb aufgrund der formschlüssigen Bewegungsübertragung einen hohen Wirkungsgrad aufweist und nur das Abtriebselement im Bedarfsfall reibschlüssig sicher arretiert bzw. gebremst wird. Weiterhin hat sie den Vorteil, daß ihre Funktion übersetzungsunabhängig ist und sie auf der Antriebsseite des Getriebes angeordnet werden kann, was wiederum dazu führt, daß sie klein dimensioniert werden kann. Schließlich brauchen bei ihr keine Axialkräfte aufgenommen zu werden. Durch die stärkere Anfederung der Klemmrollen wird, selbst bei erschwerten Bedingungen, wie Vibrationen, Stößen, tiefen Temperaturen und voreilenden Lasten ein sicherer Reibschluß gewährleistet.The pinch roller load torque lock then has the advantage that it is in advance high efficiency due to the positive movement transmission has and only the output element frictionally secure if necessary is locked or braked. It also has the advantage that its function Is translation independent and arranged on the drive side of the transmission can be, which in turn means that they are small can be. After all, no axial forces need to be absorbed become. Due to the stronger springing of the pinch rollers, even with difficult Conditions such as vibrations, shocks, low temperatures and leading loads ensure a secure frictional connection.

Durch die Parallelführung von Antriebswelle und Abtriebswelle ist es in einer besonders vorteilhaften Ausführungsform möglich, die Antriebswelle durch das Gehäuse hindurchzuführen, so daß an beiden Enden eine Betätigungsvorrichtung anschließbar und somit eine Betätigung aus dem Fahrzeuginneren und von außen möglich ist. Die Abtriebswelle wird als Hohlwelle ausgebildet, durch welche die Antriebswelle hindurchgeführt ist.Due to the parallel guidance of the input shaft and output shaft, it is in one particularly advantageous embodiment possible through the drive shaft pass the housing so that an actuator at both ends connectable and thus an actuation from the vehicle interior and is possible from the outside. The output shaft is designed as a hollow shaft, through which the drive shaft is passed.

Weiterhin hat es sich als vorteilhaft erwiesen, wenn zwischen Innenring und Außenring der Klemmrollen-Lastmomentsperre zwei Klemmrollenpaare derart angeordnet sind, daß sie in bezug auf die Drehachse des Innenrings einander diametral gegenüberliegen. Hiermit wird eine einseitige Biegebeanspruchung der Antriebswelle vermieden.Furthermore, it has proven to be advantageous if between the inner ring and Outer ring of the pinch roller load torque lock two pairs of pinch rollers in such a way are arranged so that they are each other with respect to the axis of rotation of the inner ring diametrically opposite. This creates a one-sided bending stress the drive shaft avoided.

    Die in den Fig. 1 bis 5 dargestellte Vorrichtung besteht im wesentlichen aus einem Stirnradgetriebe mit einer vorgeschalteten Klemmrollen-Lastmomentsperre.The device shown in FIGS. 1 to 5 consists essentially of a spur gear with an upstream pinch roller load torque lock.

    Durch das Getriebegehäuse 1 ist eine Antriebswelle 9 so hindurchgeführt, daß ihre beiden Enden 9.1 und 9.2 zu beiden Seiten des Getriebes angeordnet sind.Through the gear housing 1, a drive shaft 9 is passed so that their two ends 9.1 and 9.2 are arranged on both sides of the transmission.

    Auf diese Enden 9.1 und 9.2 ist eine nicht dargestellte Betätigungsvorrichtung, beispielsweise eine Handkurbel oder ein Handrad aufsteckbar.On these ends 9.1 and 9.2 there is an actuating device, not shown, for example, a hand crank or a handwheel attachable.

    Die Antriebswelle 9 ist unmittelbar mit einer Klemmrollen-Lastmomentsperre verbunden, die im folgenden näher erläutert wird.The drive shaft 9 is directly with a pinch roller load torque lock connected, which is explained in more detail below.

    Hierzu besitzt die Antriebswelle 9 einen innerhalb des Gehäuses angeordneten Innenflansch 9.3, dem ein mit dem Gehäuse 1 fest verbundener Außenring 2 sowie ein innerhalb des Außenrings 2 angeordneter Innenring 3 gegenüberliegt. Der Innenring 3 ist gegenüber dem Außenring 2 verdrehbar gelagert. Der Innenring 3 ist formschlüssig mit einer Abtriebswelle verbunden, die als Hohlwelle 4 ausgebildet ist, durch welche die Antriebswelle 9 hindurchgeführt ist. Zur Erzielung eines guten Wirkungsgrades ist die Hohlwelle 4 auf der Antriebswelle 9 über Nadellager 13 und 13.1 und im Gehäuse 1 über Kugellager 12.1 gelagert und die Antriebswelle 9 ist über Kugellager 12 im Gehäuse 1 gelagert. For this purpose, the drive shaft 9 has one arranged inside the housing Inner flange 9.3, which has an outer ring 2 firmly connected to the housing 1 as well as an inner ring 3 arranged inside the outer ring 2. The inner ring 3 is rotatably supported relative to the outer ring 2. The inner ring 3 is positively connected to an output shaft, which is a hollow shaft 4 is formed, through which the drive shaft 9 is passed. To achieve good efficiency, the hollow shaft 4 is on the drive shaft 9 via needle bearings 13 and 13.1 and in the housing 1 via ball bearings 12.1 is mounted and the drive shaft 9 is in the housing 1 via ball bearings 12 stored.

    Wie insbesondere Fig. 5 zu entnehmen, sind im Klemmspalt 5 zwischen Innenring 3 und Außenring 2 zwei Klemmrollenpaare 6.1, 6.2 und 7.1, 7.2 angeordnet und zwar so, daß sie in bezug auf die Drehachse D des Innenrings 3 einander diametral gegenüberliegen. Jede der Klemmrollen 6.1, 6.2, 7.1 und 7.2 steht unter der Wirkung von zwei nebeneinander angeordneten Druckfedern, von denen in Fig. 5 die Druckfedern 8.1 bis 8.4 sichtbar sind, durch welche sie in eine Klemmstellung gedrückt wird, in welcher der Innenring 3 und damit die das Abtriebselement darstellende Hohlwelle 4 durch die Klemmwirkung gegen Verdrehung verriegelt sind. Der Innenflansch 9.3 der Antriebswelle 9 ist einerseits über am Innenring 3 angeordnete Mitnehmerstifte 10.1 und 10.2, die mit Spiel in Bohrungen 10.3 und 10.4 des Innenflansches 9.3 eingreifen, mit diesem gekoppelt und andererseits weist er Betätigungsstifte 11.1 und 11.2 auf, welche in den Klemmspalt 5 hineinragen und jeweils eine Klemmrolle 6.1 und 7.1 bzw. 6.2 und 7.2 jedes Klemmrollenpaares gegen die Kraft der Druckfedern in eine Freigabestellung drücken. Damit ist bei Einwirkung eines antreibenden Drehmoments die Drehung des Innenrings 3 und damit der Hohlwelle 4 freigegeben. Die geometrischen Bedingungen zwischen Außenring 2, Innenring 3 und den Klemmrollen 6.1, 6.2, 7.1, 7.2 sind derart gewählt, daß der Klemmwinkel im Bereich zwischen 4,5° und 7° liegt. Als besonders vorteilhaft hat sich ein Klemmwinkel von 5,75° erwiesen.5, there are 5 in the clamping gap between the inner ring 3 and outer ring 2 two pairs of pinch rollers 6.1, 6.2 and 7.1, 7.2 arranged in such a way that they are mutually related with respect to the axis of rotation D of the inner ring 3 diametrically opposite. Each of the pinch rollers 6.1, 6.2, 7.1 and 7.2 is under the effect of two compression springs arranged side by side, 5 of which the compression springs 8.1 to 8.4 are visible, through which they is pressed into a clamping position in which the inner ring 3 and thus the the hollow shaft 4 representing the output element due to the clamping action Twist are locked. The inner flange 9.3 of the drive shaft 9 is on the one hand Via driver pins 10.1 and 10.2 arranged on the inner ring 3, which with Intervene in the holes 10.3 and 10.4 of the inner flange 9.3, with this coupled and on the other hand it has actuating pins 11.1 and 11.2, which protrude into the nip 5 and each have a pinch roller 6.1 and 7.1 or 6.2 and 7.2 of each pair of pinch rollers against the force of the compression springs press into a release position. This is a driving force Torque the rotation of the inner ring 3 and thus the hollow shaft 4th Approved.
