Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum Verriegeln der Lenkung eines Kraftfahrzeugs mittels eines Elektromotors, der über ein Untersetzungsgetriebe und ein Kurvengetriebe einen in einem stationären Gehäuse verschiebbar gelagerten Riegel zum Eingriff in ein Riegelelement einer drehbar gelagerten Lenksäule betätigt.The The invention relates to a device for locking the steering a motor vehicle by means of an electric motor, via a Reduction gear and a cam gear slidable in a stationary housing mounted latch for engagement in a locking element of a rotatable mounted steering column actuated.
Ein
derartige Einrichtung ist z.B. durch die
Der Erfindung liegt die Aufgabe zugrunde, die Anforderungen an die Verriegelung durch eine besonders leichte und kostengünstige Konstruktion zu erfüllen.Of the Invention is based on the object, the requirements for the lock to meet by a particularly lightweight and inexpensive construction.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 angegebenen Merkmale gelöst. Derartige flach bauende reibungsarme Hypozykloidgetriebe sind üblicherweise mit einem deformierbaren Zahnriemen versehen der mittels einer Excenterscheibe mit einem äußeren Gehäusezahnkranz von geringfügig höherem Durchmesser in Eingriff gelangt. Das Hypozykloidgetriebe ermöglicht eine besonders große Übersetzung, so dass ein drehmomentschwächerer Antriebsmotors verwendet werden kann. Diese selbsthemmende Getriebebauart erschwert die gewaltsame Entriegelung erheblich selbst bei unvollständiger Verriegelung. Außerdem wird die unbeabsichtigte Verriegelung während der Fahrt z.B. durch Vibrationen sowie eine Beschädigung bei gehemmter Riegelbewegung vermieden. Der gleichmäßige Bewegungsablauf ergibt gleichmäßig schwache Antriebsgeräusche und dämpft die störenden Rastgeräusche.These The object is specified by that in the characterizing part of claim 1 Characteristics solved. Such low-profile hypocycloid low-friction gears are common provided with a deformable toothed belt by means of an eccentric disc with an outer housing sprocket of slight higher Diameter engaged. The Hypozykloidgetriebe allows a very large translation, so that a torque weaker Drive motor can be used. This self-locking gearbox design complicates the violent unlocking considerably even with incomplete locking. In addition, will unintentional locking while driving e.g. by Vibrations as well as damage avoided with inhibited locking movement. The smooth movement results equally weak drive noise and dampens the disturbing ones Rest noise.
Montagetechnisch besonders vorteilhaft ist die koaxiale bzw. achsparallele Anordnung der der Antriebs- und Getriebeeinheiten in einer kompakten Bauweise, die den Einbau in unterschiedliche Lenksysteme begünstigt.Technically assembly Particularly advantageous is the coaxial or axially parallel arrangement that of the drive and gear units in a compact design, which favors the installation in different steering systems.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den in den Ansprüchen 2 bis 8 gekennzeichneten Merkmalen.advantageous Further developments of the invention will become apparent from the in claims 2 to 8 marked features.
Durch den großen Verweilwinkel nach Anspruch 2 kann auf eine präzise Winkelpositionierung der Kurvenscheibe verzichtet werden, so dass hierfür nur einfache Tastelemente, z.B. in Form von Kontaktfedern.By the big one Dwell angle according to claim 2 can be on a precise angular positioning of Be omitted cam, so this only simple feeler elements, e.g. in the form of contact springs.
Die im wesentlichen dreieckige Kurvenscheibe in der Art eines Exzenternockens nach den Ansprüchen 4 und 5 mit einer Ecke in der Drehachse bewirkt während einer Volldrehung im wesentlichen vier Bewegungszyklen des Schiebers mit dem Riegel:
- 1. das Schieben in die verriegelte Stellung,
- 2. das Halten in der verriegelter Stellung,
- 3. das Schieben in die entriegelte Stellung und
- 4. das Halten in der entriegelten Stellung.
- 1. pushing into the locked position,
- 2. holding in the locked position,
- 3. sliding into the unlocked position and
- 4. holding in the unlocked position.
Durch die Haltestellungen 2. und 4. ist es möglich, den Antriebsmotor mit einfachen Mitteln zu bremsen, ohne das hohe Anforderungen and die Genauigkeit der Winkelposition gestellt werden müssen.By the stops 2. and 4. it is possible to use the drive motor simple means to brake, without the high requirements and the Accuracy of the angular position must be made.
Durch die Ausformung der Rastkurven nach Anspruch 6 wird eine hohe Entriegelungskraft zu Beginn des Entriegelungszyklus ausgeübt. Falls diese Kraft nicht ausreicht, um den Riegel zu entriegeln, fällt die Kraft durch die Federrastung ab. Dadurch wird die Motorlast wieder verringert, was den Motor schont und die akustisch unerwünschte Drehzahlvariation des Motors minimiert.By the shape of the locking curves according to claim 6 becomes a high unlocking force exercised at the beginning of the unlocking cycle. If this force is not sufficient to unlock the latch, the force falls through the spring catch from. As a result, the engine load is reduced again, which protects the engine and the acoustically undesirable Speed variation of the motor minimized.
Durch die Feder nach Anspruch 7 wird die stabile Entriegelungsstellung gesichert.By The spring according to claim 7, the stable unlocking position secured.
Durch die zweiteilige Ausgestaltung des Riegels nach Anspruch 8 ist es mit geringem Aufwand möglich, die Einrichtung unter schiedlichen Riegelelementen der Lenksäule mit unterschiedlichen verschleißfesten Rastspitzen anzupassen bei gleichbleibendem Grundkörper gewichtsparend anzupassen.By the two-part embodiment of the bolt according to claim 8 is possible with little effort, the device under different locking elements of the steering column with different wear-resistant Ratchet tips adapt to weight while maintaining the same body weight adapt.
