Description
Die vorliegende Erfindung betrifft einen Aktuator, insbesondere als Fahrwerksaktuator eines Kraftfahrzeuges ausgebildete Aktuatoren. Derartige Aktuatoren können eingesetzt werden, um beispielsweise die Spur oder den Sturz der Räder aktiv zu verstellen. Zu diesem Zweck lenkt der Aktuator einen Lenker an, der beispielsweise als Spurstange ausgebildet sein kann. Ein Lenker im Sinn der Erfindung kann ein Bauteil sein, das starr oder gelenkig mit dem Aktuator verbunden ist.The present invention relates to an actuator, in particular as a Fahrwerksaktuator a motor vehicle trained actuators. Such actuators can be used to actively adjust, for example, the track or the fall of the wheels. For this purpose, the actuator directs a handlebar, which may be formed for example as a tie rod. A link in the sense of the invention may be a component which is rigidly or hingedly connected to the actuator.
Aus
Aufgabe der Erfindung war es, einen Aktuator nach den Merkmalen des Oberbegriffs des Anspruchs 1 anzugeben, bei dem ein einwandfreier Betrieb gewährleistet ist.The object of the invention was to provide an actuator according to the features of the preamble of claim 1, in which a perfect operation is guaranteed.
Erfindungsgemäß wurde diese Aufgabe durch den Aktuator gemäß Anspruch 1 gelöst. Dadurch, dass eine zwischen dem Elektromotor und dem Schlingfederfreilauf wirksam angeordnete Labyrinthdichtung vorgesehen ist, wird betriebsbedingter Abrieb des Schlingfederfreilaufs innerhalb des Schlingfederfreilaufs zurückgehalten; ein Zugang zu dem Elektromotor ist mit der Labyrinthdichtung verhindert. Die Labyrinthdichtung ist wirksam in dem Sinn, dass Abrieb oder andere Stoffe aus dem Schlingfederfreilauf nicht an der Labyrinthdichtung vorbei in den Bereich des Elektromotors gelangen.According to the invention, this object has been achieved by the actuator according to claim 1. Characterized in that an effectively arranged between the electric motor and the wrap spring labyrinth seal is provided, operational abrasion of the wrap spring freewheel is retained within the Schlingfederfreilaufs; Access to the electric motor is prevented with the labyrinth seal. The labyrinth seal is effective in the sense that abrasion or other material from the wrap spring free run does not pass the labyrinth seal in the area of the electric motor.
Die Labyrinthdichtung hat an dieser Stelle besondere Vorteile gegenüber anderen Dichtungen. Eine einfache Spaltdichtung kann den Abrieb nicht einwandfrei zurückhalten. Eine schleifende Dichtung bringt ebenfalls nicht den erwünschten Erfolg, weil unter einer wirksamen Magnetkraft der Abrieb unter eine schleifende Dichtlippe gelangen und diese beschädigen kann. Demgegenüber ist erfindungsgemäß das Labyrinth entgegen einer wirkenden Magnetkraft angeordnet. Der Abrieb kann jedoch nicht entgegen einer von außerhalb der Labyrinthdichtung einwirkenden Magnetkraft durch das Labyrinth wandern, so dass eine einwandfreie Funktion des Fahrwerkaktuators sichergestellt ist. Das Labyrinth weist vorzugsweise eine mehrfache Umlenkung auf, so dass der Abrieb jedenfalls nicht entgegen der Magnetkraft durch den Abschnitt des Labyrinths wandern kann, dessen Verlauf der wirksamen Magnetkraft entgegengerichtet ist. Selbst wenn sich Abrieb an der Labyrinthdichtung sammelt, ist nach wie vor einwandfrei verhindert, dass dieser Abrieb in den Bereich des Elektromotors gelangt.The labyrinth seal has special advantages over other seals at this point. A simple gap seal can not hold back the abrasion properly. A sliding seal also does not bring the desired success, because under an effective magnetic force of the abrasion can get under a sliding sealing lip and damage it. In contrast, according to the invention, the labyrinth is arranged counter to an acting magnetic force. However, the abrasion can not migrate contrary to a force acting outside of the labyrinth seal magnetic force through the labyrinth, so that a proper function of the Fahrwerkaktuators is ensured. The labyrinth preferably has a multiple deflection, so that the abrasion can not in any case migrate contrary to the magnetic force through the portion of the labyrinth, the course of which is opposite to the effective magnetic force. Even if abrasion collects on the labyrinth seal, it is still perfectly prevented that this abrasion reaches the area of the electric motor.
Die Labyrinthdichtung ist vorzugesweise zwischen dem Rotor des Elektromotors und einer als Schlingfederhülse ausgebildeten Schlingfederaufnahme des Schlingfederfreilaufs angeordnet.The labyrinth seal is preferably arranged between the rotor of the electric motor and designed as a wrap spring wrap spring recording of Schlingfederfreilaufs.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben, wobei die Vorteile dieser Ausgestaltungen anhand eines in vier Figuren abgebildeten Ausführungsbeispieles erläutert werden. Es zeigen:Further advantageous embodiments of the invention are specified in the dependent claims, wherein the advantages of these embodiments are explained with reference to an embodiment shown in four figures.

Accordingly, two coaxial hollow cylindrical projections can be formed on the wrap spring, which engage in each case between two mutually coaxially arranged Borden.
