Definitions

  • Aligning device for aligning a measuring aid of a sketch
  • the invention relates to an alignment device for aligning a measuring aid of a testing device for testing and / or calibrating a test stand, in particular for motor vehicles. Furthermore, the invention relates to a test apparatus, a test stand and a method for aligning a measuring aid of a test apparatus for testing and / or calibrating a test stand.
  • a test apparatus e.g. Rolling test stands
  • forces are measured, which during acceleration and braking, i. at a negative acceleration, act on the wheel treads of the tires.
  • a motor vehicle wheel stands on a test roller, which is connected to a drive motor via a drive shaft.
  • the drive motor is mounted pendulum.
  • a counter support is designed as a force sensor. If the motor vehicle wheel is accelerated or decelerated, the resulting force is transmitted to the test roller via a force introduction area. This force is measured via the counterstay, ie the force sensor.
  • the measurement of the force takes place indirectly via a torque measurement.
  • a first lever extends from the center of the test roller to the area of force application on the roller surface.
  • a second lever extends from the center of the test roller to the counterstay. The force on the counter-support thus results in the ratio of the first to the second lever.
  • a reference force is initiated directly on the force sensor. This is done by attaching power levers on which a weight is applied, or by force lever, in whose power flow a reference force sensor is installed.
  • test levers with reference weights also have the disadvantage that all weights are subject to gravitational attraction. Therefore, the local gravitational value should actually be known and taken into account.
  • test levers loaded with reference weights are also subject to many other influences that arise when loading. Thus, any load causes the lever to deform, which in turn results in a change in the lever ratio and must be corrected again.
  • test stand must be opened for calibration and the power lever must be mounted.
  • test roller It is known to set up a test axis on the test roller.
  • the wheels of the test axle are braked and the counter-support torque is measured at the test axle in the form of a torque measurement.
  • the introduced force is then compared with the force displayed on the chassis dynamometer.
  • test bench does not have to be opened. However, this test method is also torque-based and therefore subject to the same errors. A change in the wheel diameter of the test axis also leads here to a change in the leverage ratios. In addition, many other factors exist that lead to a falsification of the measurements. In accordance with legal requirements, a test bench must be regularly calibrated with high accuracy. However, this high accuracy is not achieved, for example due to the wear of the test roller, which is not included in the measurement, with previous testers.
  • DE 20 2017 101 176 discloses a device for testing and / or calibrating a test stand with a measuring device, which is designed to measure a force acting on the outer circumference of a test roller of the test bench tangential force.
  • the tangential force is measured on the outer circumference of the test roller. Since the tangential force is measured directly, there is no need for indirect force measurement via inaccurate torque sensors or the like. Also wear of the test roller have no negative influence on the test or calibration due to the direct measurement.
  • a band and a fastening device can be provided.
  • the fastening device can be fastened or fastened to the test roller of the test stand.
  • the test roller must have a mounting option for the band, which does not exist in conventional test stands. Previously used test rollers must therefore be modified or replaced to retrofit the test benches accordingly. For new test rollers, however, a test roller can be provided with a corresponding mounting option equal.
  • One end of the tape is thus passed through the fastening device, e.g. a screw, attached to the test roller.
  • the other end of the band is connected or connectable to the measuring unit of the measuring device.
  • the tape preferably wraps around the test roll by at least 180 °, 200 °, 220 °, 250 °, 270 °, 300 °, 330 °, 350 ° or 360 °.
  • the angle at which the tape is connected to the measuring unit is not fixed, which may possibly lead to a falsification of the measurement result.
  • the measuring unit In order to achieve an optimum angle, the measuring unit must first be precisely positioned and adjusted. This is associated with a high expenditure of time and concomitantly also with high costs. It is therefore an object of the invention to provide an alignment device for aligning a measuring aid of a testing device, a testing device, a test stand and a method for aligning a measuring aid of a testing device, which in a simple and cost-effective manner a precise testing or calibration allows.
  • the alignment device for aligning a measuring aid of a test device for testing and / or calibrating a test bench comprises a holding device for holding the measuring aid.

  • the holding device In the held state of the measuring aid, the holding device can be moved to the test position. If a measuring aid is included in the holding device, the measuring aid can thus be aligned at a certain angle. If the measuring aid is aligned, an exact measurement is possible.

  • test and / or calibration is based on torque, as is the case with the actual torque-based measurement of the motor vehicles on the test bench.
  • Negative effects e.g. due to wear and tear of the test roller, are not recognized. It is therefore particularly in test benches, which operate by means of a torque-based measurement, advantageous to use in the test or when calibrating the test bench, an alternative measuring device, which is not based on a torque measurement.
