Abstract
Description
Die Erfindung betrifft einen Radarsensor gemäß dem Oberbegriff des Anspruchs 1.The The invention relates to a radar sensor according to the Preamble of claim 1.
Solche Radarsensoren werden in Kraftfahrzeugen als Signalgeber für Fahrerassistenzsysteme eingesetzt, um z. B. Abstandswarnungen auszugeben oder automatisch eine Geschwindigkeit zu regeln. Die Radarsensoren sind in der Regel an dem Kraftfahrzeug verdeckt z. B. eingebaut und weisen in eine bestimmte Richtung, meist in Fahrtrichtung. Der verdeckte Einbau erfolgt z. B. zwischen einer Karosserie und einem vorderen Stoßfänger des Kraftfahrzeugs.Such Radar sensors are used in motor vehicles as a signal generator for Driver assistance systems used to z. B. output distance warnings or to automatically regulate a speed. The radar sensors are usually hidden on the motor vehicle z. B. installed and point in a certain direction, mostly in the direction of travel. The covert Installation takes place z. B. between a body and a front Bumper of the motor vehicle.
Damit die Radarsensoren ausreichend genaue Signale ausgeben, ist ihre exakte Ausrichtung entsprechend mindestens einer bestimmten Hauptstrahlrichtung erforderlich.In order to the radar sensors output sufficiently accurate signals is theirs exact alignment according to at least one particular main beam direction required.

Aufgabe der Erfindung ist es, einen Radarsensor so weiter zu entwickeln, dass eine Justage auch im verdeckt eingebauten Zustand problemlos möglich ist.task the invention is to develop a radar sensor so on that an adjustment even in the concealed installed state easily possible is.
Die Aufgabe ist durch die Merkmale des Anspruchs 1 gelöst. Jede der Einstellschrauben ist mittels eines Kegelradgetriebes antreibbar, wobei zwischen einem Abtriebsrad des Kegelradgetriebes und der Einstellschraube ein Vielkantstab angeordnet ist, der längs verschiebbar in der Einstellschraube gelagert ist. Hierdurch ist der Angriff für ein Werkzeug auf das Antriebsrad rechtwinklig zu einer Längsachse der Einstellschraube ausgerichtet; ein Radialwinkel des Antriebsrads ist bei der Herstellung der Halterung wählbar, so dass der günstigste Angriffspunkt – z. B. von oben oder von unten – abhängig von der Einbausituation festgelegt werden kann. Dadurch ist eine Justage jederzeit einfach und ohne Demontage anderer Teile des Kraftfahrzeugs möglich. Der in der Einstellschraube verschiebbar gelagerte Vielkantstab dient sowohl der Kraftübertragung als auch einem Ausgleich des sich ändernden Abstands zwischen dem Kegelradgetriebe und der Einstellschraube während der Justage.The The object is solved by the features of claim 1. Each of the adjusting screws is drivable by means of a bevel gear, wherein between a driven gear of the bevel gear and the adjusting screw a Vielkantstab is arranged, the longitudinally displaceable is mounted in the adjusting screw. This is the attack for a tool on the drive wheel perpendicular to a Aligned longitudinal axis of the adjusting screw; a radial angle of the Drive wheel is selectable in the manufacture of the bracket, so that the cheapest point of attack - z. B. from above or below - depending on the installation situation can be determined. This makes an adjustment at any time easy and without dismantling other parts of the motor vehicle possible. The displaceably mounted in the adjusting Vielkantstab serves both the power transmission and a compensation the changing distance between the bevel gear and the adjusting screw during the adjustment.
Die Unteransprüche betreffen die vorteilhafte Ausgestaltung der Erfindung.The Subclaims relate to the advantageous embodiment the invention.
Das Halten und Führen des Abtriebsrads mittels eines Deckels ist einfach und sicher, wobei das Verrasten die Montage des Radarsensors erleichtert.The Holding and guiding the output gear by means of a cover is simple and safe, with locking the mounting of the radar sensor facilitated.
Das Verrasten des Antriebsrads des Kegelradgetriebes mit der Halterung erleichtert weiterhin die Montage und gewährleistet zusätzlich eine Führung des Antriebsrads.The Locking the drive wheel of the bevel gear with the bracket facilitates the assembly and ensures additionally a guide of the drive wheel.
Ein O-Ring zwischen dem Antriebsrad und der Halterung sorgt einerseits für eine Dichtung und anderseits für eine zusätzliche Hemmung des Kegelradgetriebes, so dass ein selbsttätiges Verstellen verhindert wird.One O-ring between the drive wheel and the bracket provides one hand for a seal and on the other hand for an additional Inhibition of the bevel gear, so that an automatic Adjustment is prevented.
