Description

Hierzu 1 Blatt Zeichnungen1 sheet of drawings

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Auswuchten von Kraftfahrzeugrädern an einem hochgebockten Kraftfahrzeug mit den Merkmalen gemäß dem Oberbegriff des Anspruchs 1 bzw. des Anspruchs 2.The invention relates to a method and a device for balancing motor vehicle wheels a jacked up motor vehicle with the features according to the preamble of claim 1 or of Claim 2.

Die bis jetzt auf dem Markt befindlichen Auswuchtgeräte nehmen ihre Meßr"aten an den Achsen oder Traghebeln ab. Das Fahrzeug wir·"' auf Meßblöcke abgelassen, die dann beim Antreiben eines Rades in Schwingungen versetzt werden.The balancing devices currently on the market take their measuring devices on the axles or support levers. The vehicle is lowered onto measuring blocks, which are then made to vibrate when driving a wheel.

Die mit dieser Methode erzielten Meßergebnisse werden bei belastetem Fahrzeug festgestellt.The measurement results obtained with this method are determined when the vehicle is loaded.

Es ist auch bekannt, daß das Fahrzeug hochgebockt wird, so daß die Achse an der der Schwingungsaufnehmer angesetzt wird, frei an den Federn und Stoßdämpfern hängt (DE-GM 68 08 961).It is also known that the vehicle is jacked up so that the axle on that of the vibration sensor is set, hangs freely on the springs and shock absorbers (DE-GM 68 08 961).

Dies hat jedoch den Nachteil, daß durch den hierbei erforderlichen Druck auf den Meßgeber eine Meßungenauigkeit verbleibt und somit auch am Lenkrad verspürbare Vibrationen verbleiben.However, this has the disadvantage that a measurement inaccuracy is caused by the pressure required here on the measuring transducer remains and thus noticeable vibrations also remain on the steering wheel.

Der Erfindung liegt daher die Aufgabe zugrunde, die vorstehend angeführten Nachteile zu vermeiden.The invention is therefore based on the object of avoiding the disadvantages mentioned above.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Verfahrens gemäß dem Kennzeichen des Patentanspruchs 1 sowie der Vorrichtung gemäß dem Kennzeichen des Anspruchs 2 gelöstThis object is achieved according to the invention by the features of the method according to the characteristic of Claim 1 and the device according to the characterizing part of claim 2 solved

Hierbei wird bei entlasteten Rädern gemessen. Das Fahrzeug wird so aufgebockt, daß das auszuwuchtende Rad völlig frei ist.Measurements are taken with the wheels unloaded. The vehicle is jacked up so that the to be balanced Wheel is completely free.

Die nun beim Antreiben des Rades auftretenden Vibrationen werden an dem Punkt des Fahrzeugs gemessen, wo jeder Fahrer das lästige Vibrieren am stärksten empfindet, nämlich am Lenkrad oder an einem anderen mit der Lenksäule unmittelbar verbundenen Teil im Fahrgastraum des Fahrzeugs.The vibrations that now occur when driving the wheel are measured at the point on the vehicle where every driver feels the annoying vibrations the most, namely on the steering wheel or on another directly connected to the steering column part in the passenger compartment of the vehicle.

Entgegen der landläufigen Meinung, Auswuchten auf der stationären Wuchtmaschine sei das Optimale, das in dieser Hinsicht getan werden kann, wird hierdurch ein weiterer Beitrag hinsichtlich Fahrkomfort, Verschleißminderung und Fahrsicherheit geleistet.Contrary to popular belief that balancing on the stationary balancing machine is the best thing that can be done in can be done in this regard, this makes a further contribution in terms of driving comfort, wear and tear and driving safety provided.

Patentansprüche:Patent claims: 1. Verfahren zum Auswuchten von Kraftfahrzeugrädern am hochgebockten Kraftfahrzeug, bei dem das Rad auf eine bestimmte Drehzahl angetrieben wird und bei dem mittels eines am Kraftfahrzeug befestigbaren Schwingungsaufnehmers Signale an eine Meßeinrichtung gegeben werden über welche die Größe der Unwucht angezeigt wird und stroposkopische Lichtblitze erzeugt werden, dadurch gekennzeichnet, daß die Schwingungen am Lenkrad oder an einem anderen mit der Lenksäule unmittelbar verbundenem Teil im Fahrgastraum des Fahrzeugs aufgenommen werden.1. A method for balancing motor vehicle wheels on the jacked up motor vehicle, in which the wheel is driven to a certain speed and by means of a on the motor vehicle attachable vibration sensor signals are given to a measuring device via which the size of the imbalance is displayed and stroposcopic flashes of light are generated thereby characterized in that the vibrations on the steering wheel or on another with the steering column directly connected part are included in the passenger compartment of the vehicle. 2. Vorrichtung zum Auswuchten von Kraftfahrzeugrädern am hochgebockten Kraftfahrzeug mit einer Einrichtung zum Antreiben des Kraftfahrzeugrads, mit einem am Kraftfahrzeug befestigbaren Schwingungsaufnehmer, der mit einer stroposkopischen Anzeige und Meßvorrichtung zusammenwirkt, dadurch gekennzeichnet, daß der Schwingungsaufnehmer eine Einrichtung zur Befestigung am Lenkrad oder an der Lenksäule aufweist.2. Device for balancing motor vehicle wheels on jacked up motor vehicle with a device for driving the motor vehicle wheel, with one attachable to the motor vehicle Vibration sensor that interacts with a stroposcopic display and measuring device, characterized in that the vibration sensor has a device for fastening on the steering wheel or on the steering column. Unwuchten treten nicht nur an Rädern und Reifen, sondern auch an Radnaben, Bremstrommeln bzw. Scheiben und Teilen der Antriebswellen auf. Querlenker und Traghebelspiele werden bei dem erfindungsgemäßen Verfahren mit gemessen und durch den entlasteten Zustand bis in das Kleinste registriert.Imbalances occur not only on wheels and tires, but also on wheel hubs, brake drums or Washers and parts of the drive shafts. Wishbones and support lever games are in the invention Procedure with measured and registered through the relieved state down to the smallest detail. Die Vibrationen am Lenkrad bzw. der Lenksäule werden an ein Meßinstrument mittels Kabel gegeben und die Position der Unwucht wird stroposkopisch bestimmt The vibrations on the steering wheel or the steering column are given to a measuring instrument by means of a cable and the position of the unbalance is determined stroposcopically Wenn an der Lenkung keine Vibrationen registriert werden, ist das Fahrzeug optimal ausgewuchtetIf no vibrations are registered on the steering, the vehicle is optimally balanced Wenn ein Fahrzeug mit der heute üblichen Finish-Balancer-Methode ausgewuchtet wird, und der Fahrzeughalter benutzt seinen Kofferraum mit dem zulässigen Gesamtgewicht, so daß das Fahrzeug vorne leichter wird, wird wieder eine Vibration an dem Lenkrad auftreten. When a vehicle is balanced using today's finish balancer method, and so are the vehicle owner uses its trunk with the permissible total weight, so that the front of the vehicle is lighter vibration will occur again on the steering wheel. Da bei dem erfindungsgemäßen Verfahren bei entlastetem Zustand ausgewuchtet wird, gibt es, ob be- oder entladen keinerlei Probleme bei PkW, LkW oder Omnibussen. Since in the method according to the invention with relieved State is balanced, there are no problems with cars, trucks or buses, whether loading or unloading.
