Abstract

Motion thread (1) comprises a hollow profile (2) arranged coaxial and/or on the same axis to the thread. The profile surrounds a part of the thread and is connected to a housing. Preferred Features: The hollow profile acts like a friction bearing. The outer profile of the hollow profile is in the shape of a triangle, square or polygon. The hollow profile is integrated into the housing.

Description

Die vorliegende Erfindung betrifft ein Bewegungsgewinde gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a movement thread according to the preamble of claim 1

Bewegungsgewinde werden in sämtlichen Bereichen des Maschinen- und Fahrzeugbaus eingesetzt, unter anderem bei Schaltaktuatoren bzw. Getriebesteller für automatisierte Getriebe.motion thread be in all areas of the machine and Used vehicle construction, including switching actuators or Gearbox for automated transmissions.

Nach dem Stand der Technik ist für die Aufnahme von Drehmomenten eine Abstützung der Gewindemutter notwendig, welche außerhalb der Spindelachse des Bewegungsgewindes angebracht ist. Beispielsweise ist bekannt, die Spindel mittels Lager zur Reduktion der Querkräfte abzustützen. Diese Maßnahmen resultieren in nachteiliger Weise in einem größeren Bauraumbedarf.To The prior art is for the absorption of torques requires a support of the threaded nut, which outside the spindle axis of the movement thread is attached. For example It is known to support the spindle by means of bearings to reduce the lateral forces. These measures result disadvantageously in a larger space requirement.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Bewegungsgewinde anzugeben, welches eine Drehmomentaufnahme bei geringen Bauraumanforderungen gewährleistet.Of the present invention is based on the object, a movement thread specify which torque absorption with small space requirements guaranteed.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments and advantages will become apparent from the dependent claims.

Demnach wird ein Bewegungsgewinde vorgeschlagen, bei dem die Momente mittels eines zum Bewegungsgewinde koaxial bzw. achsgleich angeordneten Hohlprofils aufgenommen werden, welches einen Teil des Bewegungsgewindes umgibt und mit dem Gehäuse verbunden ist. Hierbei kann das Hohlprofil wie ein Gleitlager wirken.Therefore a motion thread is proposed in which the moments by means of one to the movement thread coaxial or coaxially arranged Hollow profiles are added, which forms part of the movement thread surrounds and with the housing connected is. Here, the hollow profile can act as a sliding bearing.

Durch die erfindungsgemäße Konzeption wird in vorteilhafter Weise kein zusätzlicher Bauraum für die Abstützung zur Momentenaufnahme benötigt.By the concept of the invention is advantageously no additional Space for the support needed for moment recording.

Die Erfindung wird im folgenden anhand der beigefügten Figur, welche eine Schnittansicht einer bevorzugten Ausführungsform eines Bewegungsgewindes gemäß der vorliegenden Erfindung darstellt, beispielhaft näher erläutert.The Invention will be described below with reference to the accompanying figure, which is a sectional view a preferred embodiment a movement thread according to the present Invention represents exemplified in more detail.

Wie aus der Figur ersichtlich, erfolgt die Momentenabstützung bei dem erfindungsgemäßen Bewegungsgewinde 1 mittels eines koaxial zum Bewegungsgewinde angeordneten Hohlprofils 2. Der Schaltfinger des dargestellten Bewegungsgewindes ist mit 3 bezeichnet.As can be seen from the figure, the torque support takes place in the movement thread according to the invention 1 by means of a coaxial with the movement thread arranged hollow profile 2 , The shift finger of the illustrated movement thread is with 3 designated.

Gemäß der Erfindung kann die Ausführung des Außenprofils 4 des Hohlprofils 2 beliebige Formen annehmen mit Ausnahme der Kreisform. So kann das Außenprofil 4 des Hohlprofils 2 beispielsweise rechteckig, dreieckig, oder auch polygonförmig ausgebildet sein.According to the invention, the execution of the outer profile 4 of the hollow profile 2 take any shape except the circular shape. So can the outer profile 4 of the hollow profile 2 For example, be rectangular, triangular, or polygonal.

Vorzugsweise ist das Hohlprofil 2 zur Momentenaufnahme in das Gehäuse (nicht dargestellt) integriert. Hierbei kann das Hohlprofil mittels einer Presspassung, form- oder kraftschlüssig mit dem Gehäuse verbunden sein.Preferably, the hollow profile 2 for torque absorption in the housing (not shown) integrated. Here, the hollow profile by means of a press fit, be positively or non-positively connected to the housing.
