  • WHEEL GEOMETRY DATA AXLE GEOMETRY DATA
  • BODY MOVEMENT DATA WITH ALREADY MANUFACTURED WHEEL BRANDS
  • the invention relates to a device for determining wheel, axle geometry and / or movement data of the body of a motor vehicle relative to the wheel having the rim and tire, with a camera arrangement with which distinguishable wheel marks that are present at least on the wheel can be detected, and with an evaluation device downstream of the camera arrangement.
  • a device of this type is shown in DE 197 57 760 A1.
  • a camera arrangement is provided on the test station, with which, from at least two different perspectives, a marking device from a reference feature arrangement fixed to the test station, at least one Body feature and at least one wheel feature for determining the wheel and / or axle geometry of motor vehicles is detected while driving past the camera arrangement.
  • the wheel turning plane can be precisely determined and a rim runout can be determined.
  • the driving axis the single track for each wheel, the total track for each wheel pair, the camber for each wheel, a wheel offset front / rear, side offset right / left, track width difference and track width and axle offset can be calculated.
  • the body features the state of deflection or load of each wheel and / or the inclination of the body in the longitudinal and transverse directions can also be recorded.
  • DE 1 97 57 763 A1 specifies a similar device for determining the wheel and / or axle geometry of motor vehicles, but the determination of the vehicle-specific data takes place when the motor vehicle is at a standstill.
  • the wheel brands are designed by a manufacturer during manufacture on the rim, a wheel cap or the tire and that to differentiate the wheel brands, all wheel brands are designed differently, one wheel brand as the reference wheel brand is designed differently from the others, the differentiation of the other wheel marks by means of the evaluation device based on their position with respect to the reference wheel mark, or all wheel marks are of identical design, the wheel marks being differentiated by means of the evaluation device based on their position with respect to a wheel feature present on the wheel.
  • the wheel brands are already provided during manufacture and thus permanently on the wheel, in particular the rim or the wheel cap, they do not need to be attached before a measurement.
  • This offers the possibility that the measurement can be carried out in the manner of a service, for example at the entrance to a workshop or petrol station, using a suitably installed camera arrangement and the driver can be informed by the workshop personnel, for example, of a faulty lane or an unfavorable fall.
  • body features for example characteristic contours and type data stored in the evaluation device, further statements can be made, for example on a deflection or vibration behavior and thus suspension components.
  • the access route can be designed with defined bumps, for example.
  • the wheel brands and the reference wheel brand on the rims or the wheel covers can also be used as a design element.
  • a valve breakthrough or a company symbol can be used as a wheel feature to identify the different wheel brands according to their position.
  • the camera arrangement is arranged on a test station, the body or at least one wheel so that it can be pivoted or fixed by means of a holder.
  • the different positions of the camera result in different reference systems which are used by the evaluation device to determine the measurement data.
  • a favorable design of the device for the simple determination of measurement data on the wheel and / or axle geometry or of movement data of the wheel, the body and also the body relative to the wheel or different wheels consists in that the axis of rotation of a measured wheel by simultaneous detection of the wheel marks and at least one body mark is determined that the direction of the driving axis of the motor vehicle in the evaluation device on the basis of the detection of a movement path of the at least one body mark is determined when driving past the camera arrangement positioned at the test station and that the position of the axis of rotation of the wheel is determined with respect to the determined verticals and the direction of the driving axis.
  • Fig. 1 is a schematic representation of a test station with a camera arrangement for detecting a wheel and part of the body in front view or rear view and
  • Fig. 2 shows a possible formation of wheel features on a rim.
  • FIG. 1 On a test station by means of a camera arrangement 2, which can have several cameras for observation from different perspectives, several wheel marks 1 .2, 1 .3, 1 .4 arranged on a wheel 1 0 and an assigned reference wheel mark 1 .1 and / or a wheel feature 1 .4 (cf. FIG. 2) together with body marks present on a body of a motor vehicle.
  • the body marks can be characteristic features of the body 3 or specially attached body marks, for which purpose conventional fastening means (such as gluing, suction, adhesive means, magnetic adhesives, Velcro connections, rubber holders or tacking elements) are suitable. However, it is favorable to characteristic features of the body to be used if the measurement should be carried out quickly.
  • wheel marks 1 .2, 1 .3, 1 .4 receptacles are provided in a rim 1 for wheel nuts, one of which is used as a reference wheel mark 1 .1 to distinguish the other wheel marks 1 .2, 1 .3, which are of identical design. 1 .4 is formed.
  • a clear distinction between the individual wheel brands can then be made in the evaluation device in accordance with the sequences or positioning of the individual wheel brands.
  • the individual wheel brands 1 .2, 1 .3, 1 .4 can be differentiated by means of the evaluation device.
  • the wheel marks 1 .2, 1.3, 1 .4 or also the reference wheel mark 1.1 and the wheel feature 1 .5 are made on the rim 1 by the manufacturer or alternatively on a wheel cap and are thus arranged rigidly to one another.
  • axle geometry and / or movement data of the body 3, for example relative to the wheel 10 no further manipulations need to be carried out on the vehicle, so that the measurement, for example, while the vehicle is being driven into a workshop or petrol station by means of suitably positioned cameras can be made.
  • the parameters specified in detail in the publications DE 197 57 960 A1 and DE 197 57 763 A1 mentioned at the beginning can be recorded as measured variables.
  • a reference feature arrangement that is fixed to the test station can also be provided, which is arranged, for example, in an oscillating manner at the test station.
  • the camera arrangement 2 can also be attached to the wheel 10 or the body 3 by means of a suitable holder, which results in different reference systems which are taken into account by means of the evaluation device.
  • the device can easily determine a driving axis of the vehicle due to the path of movement of one or more body marks and with additional determination of the vertical direction on the basis of a reference feature arrangement or from in the evaluation device stored data determine an axis of rotation of the wheel 10.
  • the rotary planes of the different wheel brands 1 .1, 1 .2, 1 .3, 1 .4 the rotary plane of the wheel 10 can be exactly determined while compensating for a rim runout. With these measures, the corresponding measurement data can then be obtained, as explained in more detail in the cited documents (it being pointed out that a subsequent application for the German patent application 199 34 864 is filed, claiming the priority of this application, which contains all of its features ).

Abstract

Un dispositif de caméra (2), qui peut être disposé sur la carrosserie (3), permet de saisir des marques de roues existant sur au moins une roue (10) et distinctes les unes des autres. Ces marques de roues sont réalisées par le constructeur dès la fabrication sur les jantes (1), les enjoliveurs ou les roues, toutes étant différentes pour une meilleure différentiation, ce qui simplifie un procédé de mesure déjà simple. Une marque de roue constitue une référence. La carrosserie (3) est également dotée de marques. On peut ainsi être renseigné sur l'état de la suspension (4).
