Abstract
Description
Die Erfindung betrifft einen Getriebemotorantrieb, insbesondere für eine kombinierte Kraftfahrzeugbremse mit elektromotorisch betätigbarer Parkbremsvorrichtung nach den Merkmalen vom Oberbegriff vom Patentanspruch 1.The invention relates to a gear motor drive, in particular for a combined motor vehicle brake with an electric motor-operated parking brake device according to the features of the preamble of claim 1.
Prinzipiell sind Getriebemotorantriebe universell bei einem Kraftfahrzeug einsetzbar. Eine bevorzugte und vergleichsweise neuartige Applikation erfolgt unmittelbar direkt an einer Kraftfahrzeugbremsvorrichtung.In principle, gear motor drives are universally applicable to a motor vehicle. A preferred and relatively novel application takes place directly directly on a motor vehicle brake device.
Eine elektromechanisch betätigbare Radbremse vom sogenannten Schwimmsatteltyp umfasst prinzipiell ein Bremsgehäuse und einen Halter zur fahrzeugfesten Anordnung von Bremsgehäuse und Reibbelägen am Fahrzeug. Eine erfindungsgemäße Kraftfahrzeugbremse kann prinzipiell ausschließlich elektromechanisch betätigbar sein, oder die elektromechanische Betätigung erstreckt sich ausschließlich auf eine Feststellbremsfunktion. Jeder Getriebemotorantrieb umfasst zu diesem Zweck einen Elektromotor der ein mehrstufiges Getriebe, insbesondere ein zweistufiges Schneckengetriebe, antreibt. Das Schneckengetriebe ist als Untersetzungsgetriebe ins Langsame ausgelegt. Dadurch wird der Vorteil erzielt, dass ein vergleichsweise kleiner, kostengünstiger Antriebsmotor mit vergleichsweise hoher Nenndrehzahl und verhältnismäßig niedrigem Drehmoment bei geringem Strombedarf ausgewählt werden kann, und wobei das Schneckengetriebe eine Drehmomentwandlung ermöglicht. Dadurch werden sowohl Kosten als auch Strombedarf und Dimension (Baugröße) des Elektromotors abgesenkt. Das Schneckengetriebe ermöglicht auch eine selbsthemmende Ausbildung, so dass prinzipiell eine stromlose (Park)Bremsfunktion realisierbar ist. Die Getrieberäder und insbesondere ein Abtriebsrad auf einer Ausgangsseite des Untersetzungsgetriebes stellt ein wesentliches Getriebebauteil dar, welches vergleichsweise hohe Drehmomente (zum Zuspannen der Bremse) in Richtung Abtrieb überträgt. Wegen gesetzlich definierter Zuspannkräfte einer Parkbremsfunktion in Höhe von etwa 17 Kilonewton besteht eine entsprechend hohe Beanspruchung durch Biegemomente, Axialkräfte und ähnliches, so dass dieser Lagerung besondere Bedeutung zukommt.An electromechanically actuated wheel brake of the so-called floating caliper type basically comprises a brake housing and a holder for the vehicle-fixed arrangement of brake housing and friction linings on the vehicle. A motor vehicle brake according to the invention can, in principle, be actuated exclusively electromechanically, or the electromechanical actuation extends exclusively to a parking brake function. Each geared motor drive comprises for this purpose an electric motor which drives a multistage gear, in particular a two-stage worm gear. The worm gear is designed as a reduction gear in the slow. Thereby, the advantage is achieved that a comparatively small, inexpensive drive motor with comparatively high rated speed and relatively low torque can be selected with low power consumption, and wherein the worm gear allows torque conversion. As a result, both costs and power consumption and dimension (size) of the electric motor are lowered. The worm gear also allows a self-locking training, so that in principle an electroless (parking) braking function can be realized. The gear wheels and in particular a driven gear on an output side of the reduction gear is an essential transmission component which transmits relatively high torques (for applying the brake) in the direction of the output. Due to legally defined application forces of a parking brake function in the amount of about 17 kilonewtons, there is a correspondingly high stress by bending moments, axial forces and the like, so that this storage is of particular importance.
Gattungsgemäße Getriebemotorantriebe für Kraftfahrzeugbremsen umfassen des Weiteren einen nachgeschalteten Wandler zur zusätzlichen Wandlung der rotatorischen Drehbewegung in eine translatorische (Brems-)Betätigungsbewegung.Generic gear motor drives for motor vehicle brakes further include a downstream converter for additional conversion of rotary rotational movement in a translational (brake) actuating movement.
Aus der
Es ist eine Aufgabe der vorliegenden Erfindung, einen verbesserten Getriebemotorantrieb mit einer verbesserten, beanspruchungsgerecht sowie spielfrei ausgebildeten Lagerung von Getrieberädern von einem Untersetzungsgetriebe bei kostengünstiger Herstellung, einfacher Montage sowie reibungsarmer Funktion von den Komponenten bereitzustellen.It is an object of the present invention to provide an improved geared motor drive with an improved, stress-free and backlash-free storage of gear wheels of a reduction gear with cost-effective production, easy installation and low-friction function of the components.
Die Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale von dem unabhängigen Patentanspruch gelöst. Weitere Einzelheiten der Erfindung gehen aus Unteransprüchen zusammen mit der Beschreibung anhand der Zeichnung hervor.The object is achieved by the characterizing features of the independent claim. Further details of the invention will become apparent from dependent claims together with the description with reference to the drawings.
Die Einzelheiten und Merkmale von dem verbesserten Getriebemotorantrieb mit verbessertem Untersetzungsgetriebe, einschließlich dessen verbesserter Lagerung, wird nachstehend im Einzelnen anhand der Zeichnung exemplarisch in Applikation bei einer kombinierten Scheibenbremse beschrieben. In der Zeichnung zeigt:The details and features of the improved geared motor drive with improved reduction gear, including its improved storage, will be described below in detail with reference to the drawing by way of example in application of a combined disc brake. In the drawing shows:

Die Erfindung wurde vorstehend primär zur Applikation bei einer Radbremse mit elektromotorischer Betätigung zur Umsetzung automatisierter Parkbremseingriffe geschildert. Die Erfindung ist jedoch nicht auf derartige Applikationen in einem Kraftfahrzeug beschränkt. Vielmehr ist auch eine Anwendung bei anderen Getriebemotorantrieben, wie beispielsweise Getriebemotorantriebe für Verschlußelemente wie beispielsweise Türen, Dächer, Verdecke, Fenster oder Lenkungen prinzipiell denkbar. Denn elektromechanisch betriebene Systeme und Aktuatoren ermöglichen grundsätzlich interessante Fahrzeug-Zusatzfunktionalitäten, welche elektronisch gesteuert oder geregelt sowie fremdbetätigt, also fahrerunabhängig, umgesetzt werden können.The invention has been described above primarily for application to a wheel brake with electromotive actuation for implementing automated parking brake interventions. However, the invention is not limited to such applications in a motor vehicle. Rather, an application in other gear motor drives, such as gearmotor drives for closure elements such as doors, roofs, roofs, windows or steering systems in principle is conceivable. This is because electromechanically operated systems and actuators fundamentally make possible interesting additional vehicle functionalities, which can be electronically controlled or regulated and operated by third parties, ie independently of drivers.
