  • 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 results in the ratio of the first to the second lever.
  • a reference force is initiated directly at 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, each 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. 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. The 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.
  • many other factors exist which lead to a falsification of the measurements.
  • a test bench 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 testing devices.
  • the device for testing and / or calibrating a test bench comprises a measuring device which is designed to measure a tangential force acting on the outer circumference of a test roller of the test bench.
  • the test bench may be, for example, a test stand for motor vehicles. In principle, however, any test stands are conceivable, in particular for rolling bearings, for example in the paper and / or textile industry.
  • 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.

  • test device thus enables a simple and cost-effective manner a precise testing or calibration of a test stand.
  • the measuring device is designed to check and / or to calibrate a torque-based measurement of the test bench.
  • the measurement is based on torque. Due to the effects already described, however, such a measurement is faulty over time. It is therefore all the more important to check or calibrate precisely these torque-based measurements.
  • the test and / or calibration is also torque-based, whereby the negative effects 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.
  • a measurement of the tangent Alkraft which acts on the outer circumference of the test roller, it is advantageous because the negative effects are detected.
  • the measuring device is designed to test and / or calibrate the entire measuring chain of the test bench. While the calibration in conventional test devices only takes place from the force sensor to the measurement display, according to the invention the entire measuring chain is calibrated. The legal requirements are met in this way. In particular, mechanical wear of the test roller and / or a change of force introduction levers are taken into account. A calibration is thus always after prolonged operation when the test roll is already worn out, always exactly. Deviations in the torque-based measurement due to these effects are consequently noticed and taken into account accordingly.

  • a traction gauge can be used in particular when the test roller is driven.
  • a pressure force sensor can be used, for example, if the test roller acts as a brake. Whether the measuring unit is designed as a tensile force meter or as a pressure force sensor is ultimately due to the positioning of the measuring unit.
