Abstract
Description
Die Erfindung bezieht sich auf eine elektromechanische Lenkung mit einem koaxialen Motor, umfassend ein Lenkgetriebegehäuse, eine Lenkstange, die sich durch das Lenkgetriebegehäuse erstreckt, einen koaxial zu der Lenkstange angeordneten Elektromotor mit einem Rotor und einem Stator, und eine Kugelgewindemutter, die mit der Lenkstange in Eingriff steht und mit dem Rotor des Elektromotors derart gekoppelt ist, um ein Antriebsmoment des Elektromotors in eine Axialkraft an der Lenkstange zu übersetzen.The The invention relates to an electromechanical steering with a coaxial motor, comprising a steering gear housing, a Handlebar extending through the steering gear housing, a coaxial with the handlebar arranged electric motor with a Rotor and a stator, and a ball screw nut with the Handlebar engages and with the rotor of the electric motor is coupled to a drive torque of the electric motor in to translate an axial force on the handlebar.
Lenkungen
dieser Bauart sind beispielsweise aus der
Elektromechanische Lenkungen müssen vor ihrer Inbetriebnahme auf ihre Funktionsfähigkeit geprüft werden. Dabei wird angestrebt, schadhafte Systemkomponenten möglichst frühzeitig zu erkennen und auszusondern. Insbesondere können im Bereich des Kugelgewindetriebs und des Elektromotors Herstellungsfehler auftreten, die sich spätestens bei einer Prüfung der Funktionsfähigkeit bemerkbar machen. Die vorstehend genannten Lenkungen sind jedoch im Hinblick auf eine Prüfung dieser Systemkomponenten unvorteilhaft, da bei Feststellen eines Fehlers ein großer Handhabungsaufwand bzw. Ausschuss bei nicht demontierten Komponenten entsteht.electromechanical Steering systems must be functional before being put into service being checked. The aim is to damage defective system components to recognize and discard as early as possible. In particular, in the field of ball screw and the electric motor manufacturing errors occur at the latest noticeable in a test of functionality do. However, the above-mentioned steering are in view to an examination of these system components unfavorable, because when detecting a mistake, a large handling effort or Committee arises when not dismantled components.
Der Erfindung liegt daher die Aufgabe zugrunde, eine elektromechanische Lenkung der eingangs genannten Art zu schaffen, die ein frühzeitiges Erkennen von fehlerhaften Systemkomponenten ermöglicht.Of the Invention is therefore the object of an electromechanical To provide steering of the aforementioned type, the early detection of faulty system components.
Diese Aufgabe wird durch eine elektromechanische Lenkung gemäß Patentanspruch 1 gelöst. Die erfindungsgemäße Lenkung zeichnet sich insbesondere dadurch aus, dass der Rotor des Elektromotors an zwei axial voneinander beabstandeten Endabschnitten über jeweils ein Lager am Lenkgetriebegehäuse drehbar gelagert ist, und die Kugelgewindemutter lösbar an einen axialen Endabschnitt des Rotors angekoppelt ist.These Task is by an electromechanical steering system according to claim 1 solved. The steering system according to the invention is characterized in particular by the fact that the rotor of the electric motor at two axially spaced end sections via each bearing rotatably mounted on the steering gear housing is, and the ball screw nut releasably connected to an axial End portion of the rotor is coupled.
Hierdurch ist es möglich, für den Elektromotor und die Antriebseinheit, das heißt die Kugelgewindemutter und die Lenkstange, jeweils eine unabhängige Vorprüfung vorzunehmen, wobei der Elektromotor hierbei bereits im Lenkgetriebegehäuse montiert sein kann. Eine solche Vorprüfung ist bei den Lenkungen bekannter Bauart nicht möglich, da eine vollständige Lagerung des Elektromotors und der Antriebseinheit im Lenkgetriebegehäuse, welche bei den bekannten Lenkungen zur Vorprüfung erforderlich ist, erst durch das Zusammenfügen dieser Systemkomponenten erzielt wird. Wird bei den bekannten Lenkungen ein Fehler festgestellt, müssen die Komponenten zunächst insgesamt demontiert, die fehlerhafte Komponente ausgetauscht und die gesamte Einheit neu montiert werden. Oftmals werden der Elektromotor und die Antriebseinheit miteinander verpresst, wodurch eine Demontage zusätzlich erschwert wird. Diese im Stand der Technik bestehenden Probleme werden mit der erfindungsgemäßen Lösung behoben.hereby is it possible for the electric motor and the drive unit, that is, the ball screw nut and the handlebar, respectively to carry out an independent preliminary examination, in which the electric motor in this case already in the steering gear housing can be mounted. Such a preliminary examination is at the Steering known type not possible because a complete Bearing of the electric motor and the drive unit in the steering gear housing, which required in the known steering for pre-examination is only by assembling these system components is achieved. If an error is detected in the known steering systems, the components must first be dismantled the faulty component is replaced and the entire unit be re-assembled. Often the electric motor and the drive unit pressed together, causing a disassembly in addition is difficult. These problems exist in the prior art be with the inventive solution Fixed.
