Abstract
Description
Die Erfindung betrifft eine Getriebestufe für einen Stellantrieb, insbesondere eines Fahrzeugsitzes, mit den Merkmalen des Oberbegriffs des Anspruches 1.The Invention relates to a gear stage for an actuator, in particular a vehicle seat, having the features of the preamble of claim 1.
Aus
der
Der Erfindung liegt die Aufgabe zu Grunde, eine Getriebestufe der eingangs genannten Art zu verbessern. Diese Aufgabe wird erfindungsgemäß durch eine Getriebestufe mit den Merkmalen des Anspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.Of the Invention is based on the object, a gear stage of the beginning to improve the type mentioned. This object is achieved by a gear stage with the features of claim 1 solved. Advantageous embodiments are the subject of the dependent claims.
Bei der Relativbewegung von Ritzel und Abtrieb führen die Lochbilder von ersten und zweiten Öffnungen eine Taumelbewegung relativ zueinander aus. Dadurch, dass wenigstens ein Zwischenelement vorgesehen ist, welches mit dem Ritzel mittels wenigstens einer ersten Öffnung und mit dem Antrieb mittels wenigstens einer zweiten Öffnung in Kontakt steht, kann bei der besagten Relativbewegung von Ritzel und Abtrieb die Gleitreibung zu Gunsten einer Rollreibung verringert werden. Im Idealfall tritt gar keine Gleitreibung (d. h. kein Schlupf) zwischen den Rändern der Öffnungen und den Zwischenelementen oder sonstigen Gegenelementen mehr auf. Die Drehmomentenübertragung auf den Abtrieb erfolgt dann mit geringeren Verlusten, was den Wirkungsgrad der Getriebestufe verbessert. Gegenüber dem Abgriff mit Wälzlagern und exzentrischen Ringen ergibt sich eine konstruktiv deutlich vereinfachte und dadurch kostengünstigere Lösung von geringerem Gewicht.at the relative movement of the pinion and the output guide the hole patterns of first and second openings a wobbling motion relative to each other. Characterized in that at least one intermediate element provided which is connected to the pinion by means of at least a first opening and with the drive by means of at least one second opening is in contact, can in the said relative movement of pinion and downforce reduces the sliding friction in favor of a rolling friction become. Ideally, there is no sliding friction at all (ie no slip) between the edges of the openings and the intermediate elements or other counter elements more on. The torque transmission on the output then takes place with lower losses, which the efficiency the gear stage improved. Opposite the tap with rolling bearings and eccentric rings results in a significantly simplified design and thereby cheaper solution of lesser Weight.
Die Zwischenelemente können als massive Rollen (Bolzen) oder als hohle Rollen (Hülsen) ausgebildet sein. Entsprechend sind sie dann in den verschiedenen Öffnungen axial hintereinander gelagert, wobei zur besseren axialen Abstützung eine sandwichartige Anordnung von Abtrieb, Ritzel und einer Scheibe bevorzugt ist, oder radial geschachtelt, d. h. innen und außen mit einer abrollenden Funktionsfläche versehen sind.The Intermediate elements can be considered solid rollers (bolts) or be designed as hollow rollers (sleeves). Corresponding they are then axially behind one another in the different openings stored, with a sandwich-like for better axial support Arrangement of output, pinion and a disc is preferred, or radially nested, d. H. inside and outside with a rolling Function surface are provided.
Um eine stärkere Untersetzung von der Motordrehzahl in die Drehzahl des Abtriebs zu erreichen, können zwei Getriebestufen in Serie geschaltet werden, wobei die zwei Getriebestufen axial und/oder radial geschachtelt sein können. Gleichachsige Drehungen des Antriebs und Abtriebs der Getriebestufen benötigen keine Ausgleichselemente und ermöglichen einfache Lagerverhältnisse.Around a stronger reduction of the engine speed in the To achieve the speed of the output, two gear stages be connected in series, the two gear stages axially and / or can be nested radially. Equiaxial turns the drive and output of the gear stages need No compensation elements and allow easy storage conditions.
Die erfindungsgemäße Getriebestufe kann mit einem bürsten- oder elektronisch kommutierten Motor, an den sie abtriebsseitig angeschlossen wird, zu einem motorischen Stellantrieb kombiniert werden. Ein vorzugsweise gemeinsames Gehäuse des motorischen Stellantriebs kann, gegebenenfalls unter Hinzunahme von Deckeln oder dergleichen, abdichtend aufgebaut werden, was eine problemlose Behandlung des motorischen Stellantriebs in einem Tauchbad erlaubt.The Gear stage according to the invention can with a brush or electronically commutated motor to which they connected on the output side, to a motorized actuator be combined. A preferably common housing of the motorized actuator can, if necessary, with addition of lids or the like, are sealingly constructed, which is a easy handling of the motorized actuator in a dipping bath allowed.
Ein solcher motorischer Stellantrieb kann beispielsweise in ein lastaufnehmendes Getriebe eines Einstellers eines Fahrzeugsitzes integriert werden. Aufgrund der ho hen Untersetzung kann, falls notwendig, ein Ablaufen des lastaufnehmenden Getriebes durch eine Schlingfederbremse oder dergleichen am Rotor des Motors verhindert werden. Eine Hohlwellenbauweise erlaubt einen einfachen Anschluss einer Übertragungsstange zwischen beiden Fahrzeugsitzseiten, vorzugsweise durch eine profilierte zentrale Aufnahme in dem Antriebsbauteil für das lastaufnehmende Getriebe, also vorliegend im Abtrieb der Getriebestufe.One such motorized actuator can, for example, in a lastaufnehmendes Gearbox of an adjuster of a vehicle seat can be integrated. Due to the high reduction can, if necessary, a drain of the load-bearing transmission by a wrap spring brake or the like can be prevented on the rotor of the motor. A hollow shaft design allows easy connection of a transmission rod between the two vehicle seat sides, preferably by a profiled Central receptacle in the drive member for the load-bearing Transmission, that is present in the output of the gear stage.
