Abstract
Die Erfindung betrifft einen Spindelantrieb (1), umfassend eine ein Spindelgewinde (2a) aufweisende Spindel (2), eine ein Muttergewinde (3a) aufweisende Spindelmutter (3), wobei das Spindelgewinde (2a) und das Muttergewinde (3a) als Bewegungsgewinde (2a, 3a) ausgebildet sind und die in Drehrichtung antreibbare Spindelmutter (3) mit der axial verschiebbaren Spindel (2) über das Bewegungsgewinde (2a, 3a) in Eingriff steht. Es wird vorgeschlagen, dass das Spindelgewinde (2a) und das Muttergewinde (3a) durch ein Spannelement (10) in Längsrichtung der Spindel (2) gegeneinander verspannt sind.The invention relates to a spindle drive (1), comprising a spindle (2) having a spindle thread (2a), a spindle nut (3) having a nut thread (3a), the spindle thread (2a) and the nut thread (3a) being used as a movement thread (2a , 3a) and the spindle nut (3) drivable in the direction of rotation is in engagement with the axially displaceable spindle (2) via the movement thread (2a, 3a). It is proposed that the spindle thread (2a) and the nut thread (3a) are braced against each other by a clamping element (10) in the longitudinal direction of the spindle (2).
Description
Die Erfindung betrifft einen Spindelantrieb nach dem Oberbegriff des Patentanspruches 1 sowie einen Aktuator nach dem Oberbegriff des Patentanspruches 8. Die Erfindung betrifft auch eine Verwendung des Aktuators. The invention relates to a spindle drive according to the preamble of claim 1 and an actuator according to the preamble of claim 8. The invention also relates to a use of the actuator.
Durch die
Das Bewegungsgewinde, z. B. als Trapezgewinde ausgebildet, weist, bedingt durch die Abmessungen von Spindel- und Muttergewinde, ein Axialspiel auf, d. h. die Flanken von Trapezgewinde und Muttergewinde liegen nicht in jedem Betriebszustand spielfrei aneinander. The motion thread, z. B. formed as a trapezoidal thread, has, due to the dimensions of spindle and nut thread, an axial play on, d. H. the flanks of trapezoidal thread and nut thread are not in each operating condition without play together.
Die Erfindung umfasst die Merkmale der unabhängigen Patentansprüche 1, 8 und 9. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen. The invention comprises the features of the independent claims 1, 8 and 9. Advantageous embodiments result from the subclaims.
Nach einem ersten Aspekt der Erfindung ist bei einem Spindelantrieb vorgesehen, dass das Spindelgewinde und das Muttergewinde durch ein Spannelement in Längsrichtung der Spindel gegeneinander verspannt sind. Damit wird der Vorteil erreicht, dass die Flanken von Spindel- und Muttergewinde ständig aneinander liegen und das Axialspiel beseitigt ist. Mit dem Axialspiel einhergehende Geräusche werden damit ebenfalls unterbunden. According to a first aspect of the invention, it is provided in a spindle drive that the spindle thread and the nut thread are braced against each other by a clamping element in the longitudinal direction of the spindle. Thus, the advantage is achieved that the flanks of spindle and nut threads are constantly together and the axial play is eliminated. Noises associated with the axial play are thereby likewise suppressed.
Nach einer bevorzugten Ausführungsform ist das Spannelement als lose Mutter mit einem Innengewinde, d. h. einem zweiten Muttergewinde ausgebildet, welches mit dem Spindelgewinde in Eingriff steht. Das Spannelement übt somit über sein Innengewinde eine Axialkraft auf die Spindel aus, welche sich an den Flanken des Muttergewindes der Spindelmutter abstützt. According to a preferred embodiment, the clamping element is a loose nut with an internal thread, d. H. formed a second female thread, which is in engagement with the spindle thread. The clamping element thus exerts on its internal thread an axial force on the spindle, which is supported on the flanks of the nut thread of the spindle nut.
Nach einer weiteren bevorzugten Ausführungsform ist das Spannelement respektive die lose Mutter über ein Federelement gegenüber der Spindelmutter abgestützt. Durch das Federelement wird eine auf die lose Mutter wirkende Spannkraft erzeugt. According to a further preferred embodiment, the clamping element or the loose nut is supported via a spring element relative to the spindle nut. By the spring element acting on the loose nut clamping force is generated.
Nach einer weiteren bevorzugten Ausführungsform ist das Federelement, welches bevorzugt als Tellerfeder ausgebildet ist, gegenüber einer Hülse abgestützt, welche die lose Mutter gleitend in sich aufnimmt und fest mit der Spindelmutter verbunden ist. Die Abstützkraft des Federelements wird somit über die Hülse auf die Spindelmutter übertragen. According to another preferred embodiment, the spring element, which is preferably designed as a plate spring, supported against a sleeve which receives the loose nut slidably in and is firmly connected to the spindle nut. The supporting force of the spring element is thus transmitted via the sleeve to the spindle nut.
Nach einer weiteren bevorzugten Ausführungsform ist das Spannelement respektive die lose Mutter drehfest mit der Spindelmutter verbunden. According to a further preferred embodiment, the clamping element or the loose nut is rotatably connected to the spindle nut.
Nach einer weiteren bevorzugten Ausführungsform sind die Spindelmutter und die lose Mutter über stirnseitig angeordnete Klauen drehfest, jedoch axial verschiebbar miteinander verbunden. Damit wird erreicht, dass die lose Mutter mit der Spindelmutter synchronisiert ist und ein Verkeilen der losen Mutter mit der Spindelmutter vermieden wird. According to a further preferred embodiment, the spindle nut and the loose nut on the frontally arranged claws are rotationally fixed, but axially slidably connected together. This ensures that the loose nut is synchronized with the spindle nut and wedging the loose nut is avoided with the spindle nut.
Nach einer weiteren bevorzugten Ausführungsform ist die lose Mutter innerhalb der Hülse axial gleitend angeordnet. Damit wird erreicht, dass die lose Mutter auf ihrem Außenumfang zentriert und axial verschiebbar ist. According to a further preferred embodiment, the loose nut is arranged axially slidable within the sleeve. This ensures that the loose nut is centered on its outer circumference and axially displaceable.
Nach einem weiteren Aspekt der Erfindung bildet der erfindungsgemäße Spindelantrieb den Antrieb für einen Aktuator, welcher als einseitig oder zweiseitig bzw. als einfach oder doppelt wirkender Aktuator ausgebildet sein kann. Beim Betrieb des Aktuators wird die Spindel linear bewegt und somit ein- und ausgefahren, d. h. sie wechselt ständig ihre Bewegungsrichtung, was ein Umkehrspiel zur Folge hat – dies wird durch die erfindungsgemäße Verspannung beseitigt. Darüber hinaus wird auch ein im Ruhezustand des Spindelantriebes auftretendes Axialspiel beseitigt. According to a further aspect of the invention, the spindle drive according to the invention forms the drive for an actuator, which can be designed as a one-sided or two-sided or as a single or double-acting actuator. During operation of the actuator, the spindle is moved linearly and thus retracted and extended, d. H. It constantly changes its direction of movement, which has a backlash result - this is eliminated by the invention tension. In addition, an axial play occurring in the idle state of the spindle drive is eliminated.
Nach einem weiteren Aspekt der Erfindung wird der Aktuator für die Hinterachslenkung eines Kraftfahrzeuges eingesetzt. Auch hierbei ist von Vorteil, wenn etwaiges Spiel der Spindel unterbunden werden kann. According to a further aspect of the invention, the actuator is used for the rear axle steering of a motor vehicle. Again, it is advantageous if any game of the spindle can be prevented.
