Definitions

  • an optical measuring device with at least two image recording devices, which from at least two different perspectives include a marking device including at least one wheel feature present or arranged on a wheel and at least one a body feature and a reference feature arrangement with at least three reference features offset at least in one plane, and with an evaluation device, the detection of the marking device taking place while the motor vehicle drives past and the axis of rotation of a measured
  • the marking device comprises, in addition to at least one defined wheel feature and at least one body feature, reference features in the IVless space that are known in an evaluation device of the measuring device. The detection of the marking device takes place while evaluating all these features while the motor vehicle drives past and is relatively simple in terms of operating effort compared to devices known up to then.
  • the positions of the image recording devices can be determined precisely and the wheel plane can be calculated relative to the vehicle movement coordinates, so that the wheel and axle geometries can be determined, the determination taking place under real driving conditions.
  • the vertical direction in the measuring area and the driving axis of the vehicle are determined to measure the wheel and axle geometry data, such as toe and camber.
  • the object of the present invention is to provide a device of the type specified at the outset, with which the measurement setup and the implementation of the measurement are further simplified.
  • the mutual relation of the at least two image recording devices with regard to their position and position is therefore either before the actual measurement of the wheel and axle geometry data based on a reference feature arrangement with features known or also unknown from the outset, or during the actual measurement based on a Reference feature arrangement with features unknown from the outset.
  • Orienting the image recording devices before the actual measurement facilitates the measures for the actual measurement, for example in a workshop.
  • Arbitrary features can be used as unknown referencing features in the measuring space, wherein at least five features should be present for the evaluation, as shown by photogrammetric methods. Such features are easy to specify in a measuring room or at a test station.
  • both alternatives advantageously ensure that there is no obscuring of the points on the vehicle by a reference feature arrangement while driving past, and optimal recording conditions are created (object detail, depth of field, image scale), with the second alternative, only rzeug the characteristics or measurement points Fah and optionally displayed on the roadway and the Messeinrichtu ng out ⁇ evaluates be.
  • the distance between at least two features is known.
  • Advantageous alternative possibilities in the case of numerical referencing are that the referencing is not carried out in a complex manner at the factory, but instead is carried out absolutely individually on site on the basis of previously known positions of several wheel features and / or body features or numerically on the basis of previously unknown positions of at least five wheel characteristics and / or body features are done relatively.

In this way, rim runout compensation can be calculated or the influence of similar disturbance variables can be compensated.
  • the exact level of rotation of the wheel is also known. Changes in the position of the vehicle, which occur, for example, during steering locks to measure and adjust the axle geometry on the steered wheels or to determine the position of the handlebar axis, become uncritical in that the direction of the driving axis and / or the vertical direction is related to a body-typical coordinate system, whereby for Parameter transformation multiple body features can be used.
  • a further advantageous embodiment consists in the fact that a test station for measuring a steered wheel is provided, on which the measurement is carried out on the basis of the coordinate system typical of the body.
  • the measurements of the wheel and axle geometry data can already be carried out individually for each wheel by means of a measuring unit 1, the driving axis of the motor vehicle being determined in an evaluation device on the basis of the detection of the Marking device is determined from a movement path of the at least one body feature 6.
  • the camber of the wheel axles can be determined by determining the vertical direction, while the individual track of the wheels is determined on the basis of the determined driving axis.
  • the wheel features 3 and the body features 6 are recorded together with the at least two image recording devices 2 from at least two different perspectives and at several points in time while the motor vehicle drives past.
  • the lane features 7 are recorded simultaneously with the at least two image recording devices 2 from at least two different perspectives, once in advance or while the motor vehicle drives past.
  • the position of the axis of rotation of the wheel 5 can be exactly determined while driving past with the measuring device and evaluation device, the cycloids of each wheel feature 3 being evaluated and the orbit of the wheel feature 3 being freed from the linear movement known from the detection of the body features 6, so that only the orbital movement of the wheel features 3 remains.
  • the exact plane of rotation of the wheel 5 or the exact position of the axis of rotation of the wheel 5 is obtained.

Abstract

L'invention concerne un dispositif permettant de déterminer la géométrie d'une roue et/ou d'un essieu d'automobiles dans un espace de mesure à l'aide d'un dispositif de mesure optique avec au moins deux dispositifs de prise de vues (2) qui détectent un dispositif de marquage depuis au moins deux différentes perspectives, ainsi qu'avec un dispositif d'évaluation. La détection du dispositif de marquage intervient pendant le passage de l'automobile. Une mesure simplifiée est obtenue par le fait que le sens des verticales dans l'espace de mesure est déterminé sur la base du référençage et que pour effectuer la mesure, la position opposée et la situation (référençage) des au moins deux dispositifs de prise de vues (2) sont déterminées avec le système de caractéristiques de référence. Le référençage est effectué avant le passage du véhicule et les caractéristiques de référence sont connues ou le référençage intervient avant le passage du véhicule et au moins cinq caractéristiques de référence inconnues sont utilisées ou le référençage intervient pendant le passage du véhicule et au moins cinq caractéristiques de référence inconnues sont utilisées.
