Abstract
Description
Die Erfindung betrifft einen Lenkmomentsensor für ein Kraftfahrzeug, mit einem Gehäusemodul, welches zwei gegeneinander verdrehbare Sensorkomponenten aufweist, die die Torsion eines Torsionsstabs erfassen, welcher zwei Wellen der Lenksäule des Kraftfahrzeugs koaxial miteinander verbindet.The invention relates to a steering torque sensor for a motor vehicle, comprising a housing module which has two mutually rotatable sensor components which detect the torsion of a torsion bar which coaxially connects two shafts of the steering column of the motor vehicle.
Für den Aufbau von Steer-By-Wire-Fahrzeugen oder anders elektrifizierten Lenksystemen ist es notwendig, dass der Fahrer seinen Fahrtrichtungswunsch in die Querführungssysteme (Lenkung, Spurlageregelung) des Fahrzeugs einprägen kann. Wichtig ist hierfür neben der Messung der Winkelstellung des Lenkrades auch die Erfassung des vom Fahrer ausgeübten Lenkmomentes.For the construction of steer-by-wire vehicles or other electrified steering systems, it is necessary that the driver can memorize his desire to travel in the transverse guidance systems (steering, lane control) of the vehicle. Important in addition to the measurement of the angular position of the steering wheel and the detection of the force exerted by the driver steering torque.

Die deutsche Offenlegungsschrift
Es stellte sich die Aufgabe einen gattungsgemäßen Lenkmomentsensor für ein Kraftfahrzeug so auszugestalten, dass er besonders einfach und kostengünstig herstellbar und montierbar ist, und sich durch einen geringen Platzbedarf auszeichnet.It set itself the task of designing a generic steering torque sensor for a motor vehicle so that it is particularly easy and inexpensive to manufacture and assemble, and is characterized by a small footprint.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass eine erste Welle als Aufnahmewelle ausgebildet ist, die mit dem Lenkrad des Kraftfahrzeugs verbindbar ist und eine zweite Welle als Lenkspindel ausbildet ist, dass das Gehäusemodul an das die Lenkspindel aufnehmende Mantelrohr anfügbar ist, und dass bereits vor dem Anfügen des Gehäusemoduls an das Mantelrohr beide Wellen an dem Gehäusemodul gelagert sind.This object is achieved in that a first shaft is formed as a take-up shaft, which is connectable to the steering wheel of the motor vehicle and a second shaft is formed as a steering shaft, that the housing module is attachable to the steering shaft receiving tubular casing, and that even before the Attach the housing module to the jacket tube both shafts are mounted on the housing module.
Erfindungsgemäß sind sämtliche Bestandteile des Lenkmomentsensors, inklusive des Torsionsstabs und der mit dem Torsionsstab verbundenen beiden Wellen, noch vor der Endmontage in einem Kraftfahrzeug vollständig in bzw. am Gehäusemodul vormontiert. Der Montageaufwand zum Einbau des vormontierten Lenkmomentsensors in das Kraftfahrzeug kann dadurch sehr gering gehalten werden. Außerdem ist der Lenkmomentsensor noch vor dem Einbau vollständig auf Funktionsfähigkeit prüfbar.According to the invention, all components of the steering torque sensor, including the torsion bar and the two shafts connected to the torsion bar, are completely pre-assembled in or on the housing module before the final assembly in a motor vehicle. The assembly effort for installation of the preassembled steering torque sensor in the motor vehicle can be kept very low. In addition, the steering torque sensor is completely tested for functionality before installation.
Bereits bei der Vormontage des Lenkwinkelsensors können mechanische und elektronische Sensorkomponenten fest miteinander verbunden und dabei mit hoher Genauigkeit relativ zueinander einjustiert werden. Hierdurch wird eine besonders präzise messende Sensorik geschaffen, die auch kleine Verdrillwinkel des Torsionsstabs mit hoher Genauigkeit auflösen kann. Dies ermöglicht wiederum, einen besonders kurzen und drehsteifen Torsionsstab vorzusehen, der zusätzlich zu einem kompakten Aufbau des Lenkmomentsensors beiträgt und zudem eine besonders spielarme Betätigungshaptik ermöglicht.Already during the pre-assembly of the steering angle sensor mechanical and electronic sensor components can be firmly connected to each other and thereby adjusted with high accuracy relative to each other. As a result, a particularly precise measuring sensor is created, which can resolve even small twist angle of the torsion bar with high accuracy. This in turn allows to provide a particularly short and torsionally rigid torsion bar, in addition to a compact design contributes to the steering torque sensor and also allows a particularly low-backlash feel.
Besonders vorteilhaft ist es, im bzw. am Gehäusemodul weitere elektronische und elektromechanische Funktionskomponenten vorzusehen, die nicht unmittelbar zum Lenkmomentsensor gehören, wie zum Beispiel einen Lenkwinkelsensor und/oder diverse Lenkstockschaltermodule. Durch eine hohe Integrationsdichte kann so eine besonders kleinbauender und kostengünstiger Aufbau erreicht werden und der Aufwand beim Einbau in das Kraftfahrzeug weiter minimiert werden.It is particularly advantageous to provide further electronic and electromechanical functional components in or on the housing module which do not belong directly to the steering torque sensor, such as, for example, a steering angle sensor and / or various steering column switch modules. By a high integration density so a particularly kleinbauender and cost-effective design can be achieved and the cost of installation in the motor vehicle can be further minimized.
Vorteilhaft ist es zudem, wenn die Aufnahmewelle zur Anbindung eines Lenkrads die an einer Lenkwelle üblichen Verbindungsmittel, wie etwa eine Vielzahn- oder Sechskanthülse oder einen Vielzahn- oder Sechskantstift ausbildet oder aufweist. Hierdurch ist das Lenkrad an die Aufnahmewelle anfügbar, ohne dass konstruktive Änderungen am Lenkradskelett erforderlich werden.Moreover, it is advantageous if the receiving shaft for connecting a steering wheel forms or has the connecting means customary on a steering shaft, such as a multi-toothed or hexagonal sleeve or a multi-toothed or hexagonal pin. As a result, the steering wheel is attachable to the take-up shaft, without any structural changes to the steering wheel skeleton are required.
Weitere vorteilhafte Ausgestaltungen und Weiterbildungen des erfindungsgemäßen Lenkmomentsensors gehen aus den abhängigen Ansprüchen und der nachfolgenden Beschreibung eines Ausführungsbeispiels der Erfindung hervor.
