Abstract
Description
Die Erfindung betrifft einen verstellbaren Federträger gemäß dem Oberbegriff von Patentanspruch 1.The The invention relates to an adjustable spring carrier according to the preamble of claim 1.
Aus
der
Die Gewindespindel soll möglichst leichtgängig arbeiten, um das Antriebsmoment gering zu halten. Daraus kann das Problem erwachsen, dass ein geparktes Fahrzeug ohne Energieversorgung des Gewindespindelantriebs aufgrund des Eigengewichts des Fahrzeugaufbaus in seiner Niveaulage absinkt. Dieses Problem ist bereits bei hydropneumatischen Niveauregelsystemen bekannt und kann z. B. dazu führen, dass ein an einer Bordsteinkante abgestelltes Fahrzeug aufliegen kann oder dass sich die Fahrzeugtür nicht mehr vollständig öffnen lässt.The Threaded spindle should as possible smooth work to keep the drive torque low. That's what it can do Problem grown that a parked vehicle without power the threaded spindle drive due to the dead weight of the vehicle body sinks in its level. This problem is already in hydropneumatic Level control systems known and can, for. B. cause that a parked on a curbside vehicle can rest or that the vehicle door no longer open completely.
In
der gattungsbildenden
Aufgabe der vorliegenden Erfindung ist es für einen gattungsgemäßen verstellbaren Federträger eine Bremseinrichtung zu realisieren, die ein ungewolltes Absinken des Fahrzeugaufbaus verhindert.task The present invention is for a generic adjustable Spring carrier one To realize braking device, the unwanted drop in the Vehicle construction prevented.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Bremseinrichtung von einer Klemmmutter gebildet wird, die in die Gewindespindel eingreift.According to the invention Task solved by that the braking device is formed by a clamping nut, the engages in the threaded spindle.
Die Klemmmutter greift unmittelbar an dem Bauteil an, das für die Verstellbewegung vorgesehen ist. Dadurch wird eine kompakte Bauweise der Bremseinrichtung erreicht.The Clamping nut acts directly on the component, which is responsible for the adjustment movement is provided. This results in a compact design of the braking device reached.
In weiterer vorteilhafter Ausgestaltung ist die Klemmmutter in einem Gehäuseteil einer Gewindespindelmutter angeordnet. Diese Anordnung vereinfacht die Montage und die Verbindung mit einer Ansteuerung der Bremseinrichtung, da die Gewindespindelmutter, die mit der verstellbaren Feder verbunden ist, keine Rotationsbewegung ausführt.In Another advantageous embodiment is the clamping nut in one housing part arranged a threaded spindle nut. This arrangement is simplified the assembly and the connection with a control of the braking device, because the threaded spindle nut, which is connected to the adjustable spring is, does not rotate.
Gemäß einem vorteilhaften Unteranspruch wird die Klemmmutter von einer Federeinrichtung in die Bremsstellung vorgespannt. Die rein passive Krafteinleitung der Bremseinrichtung auf die Gewindespindel vereinfacht den Aufbau maßgeblich.According to one advantageous subclaim is the clamping nut of a spring device biased in the braking position. The purely passive application of force the brake device on the threaded spindle simplifies the structure prevail.
Die Klemmmutter führt bezogen auf die Längsachse der Gewindespindel eine Kippbetriebsbewegung aus. Schon mit einem sehr kleinen Betriebsweg bzw. Verstellwinkel der Klemmmutter kann eine deutliche Reibmomentsteigung in der Gewindespindel erreicht werden.The Clamping nut leads relative to the longitudinal axis the threaded spindle from a Kippbetriebsbewegung. Already with one very small operation path or adjustment angle of the clamping nut can be a significant Reibmomentsteigung be achieved in the threaded spindle.
Um eine möglichst einfache Ansteuerung der Bremseinrichtung zu erreichen, wird ein Bremsaktuator mit derselben Fremdenergieform versorgt, wie der Aktuator für die Gewindespindel. Sobald der Aktuator nicht mit Fremdenergie versorgt wird, kann man sehr leicht auch den Bremsaktuator von derselben Fremdenergiequelle trennen.Around one possible to achieve easy control of the braking device is a Brake actuator supplied with the same external energy form, as the actuator for the Threaded spindle. As soon as the actuator is not supplied with external energy It is very easy to use also the brake actuator of the same Disconnect external energy source.
Eine sehr vorteilhafte Bauform des Bremsaktuators wird von mehreren Piezoelementen gebildet. Piezoelemente können vergleichsweise große Kräfte erzeugen und sind sehr einfach an der Gewindespindel zu befestigen.A very advantageous design of the brake actuator is of several piezo elements educated. Piezo elements can comparatively large Generate forces and are very easy to attach to the threaded spindle.
Dazu ist vorgesehen, dass die Piezoelemente in dem Gehäuseteil für die Klemmmutter angeordnet sind.To it is provided that the piezo elements in the housing part for the Clamping nut are arranged.
